Understanding Your 2018 Chevy Suburban Remote Start

This section talks about what your remote start does and why it’s a great feature. We will look at the basics of how it works and what the typical run time is. This helps you know what to expect before we talk about extending it.

It’s all about making sure you get the most out of this handy car function.

Remote Start Basics

Your 2018 Chevy Suburban’s remote start system is a keyless entry feature. It lets you start your engine from outside the vehicle using your key fob. This is super helpful for pre-heating or pre-cooling your cabin.

It adds comfort and convenience, especially during extreme weather. You press a button, and your car’s engine turns on.

The system is designed with safety and efficiency in mind. It usually has a set run time to prevent the engine from idling for too long. This is good for the environment and saves fuel.

But what if that time isn’t quite enough for your needs? We’ll cover how to adjust that.

Default Run Time

Most factory remote start systems, including the one in your 2018 Chevy Suburban, have a default engine run time. This is typically set to around 10 to 15 minutes. It’s a safety feature.

It ensures the engine doesn’t stay on indefinitely if you forget to turn it off.

This standard time is often enough for many drivers. It allows the car to warm up slightly or cool down a bit. It gets the cabin to a more comfortable temperature before you get in.

However, some situations might call for a longer period.

Why Extend Remote Start

There are several reasons why you might want to extend the remote start time on your 2018 Chevy Suburban. If you live in an area with very cold winters, 10-15 minutes might not be enough to fully defrost your windshield or make the interior bearable. Similarly, during scorching hot summers, you might need more time to cool the cabin down effectively.

Another scenario is if you have a longer walk to your vehicle. You might start the car and then need to walk for 10 minutes before reaching it. By the time you get there, the remote start might have already shut off, negating the purpose.

Extending the time ensures your vehicle is ready when you are.

How to Extend Remote Start on 2018 Chevy Suburban

This is the core of our guide. Here we get into the practical steps for adjusting the remote start duration on your 2018 Chevy Suburban. We will focus on the most common and reliable methods.

You will learn exactly what to do to make your remote start last longer.

Using Your Vehicle’s Infotainment System

For many modern vehicles, including your 2018 Chevy Suburban, the settings for features like remote start are managed through the infotainment system. This is often the easiest and most accessible way to make changes. You don’t need special tools or software for this method.

You will typically find these settings within the vehicle’s main menu. Look for options related to “Vehicle Settings,” “Remote Start,” or “Comfort and Convenience.” It’s designed to be user-friendly. Most people can figure it out by just looking through the menus.

Navigating to Remote Start Settings

To access the remote start settings, you’ll first need to turn on your vehicle. Make sure the engine is running. Then, locate the main infotainment screen.

This is usually in the center of your dashboard. You might see a button labeled “Home” or a similar icon to bring up the main menu.

Once you are on the home screen, look for an icon or menu option that says “Settings” or “Setup.” Tap on it. Inside the settings menu, you should find categories like “Vehicle,” “Locks,” “Climate,” or “Remote Start.” Select the option that seems most relevant to remote start.

Adjusting the Run Time

Once you have found the remote start settings, you will likely see an option to adjust the engine run time. It might be presented as a slider, a dropdown menu, or a numerical input field. The available options will likely range from the default time up to a maximum allowed by the manufacturer.

For example, you might be able to choose between 10 minutes, 15 minutes, or 20 minutes. Select the desired duration. After making your selection, make sure to save or confirm the changes.

There’s usually a “Save,” “Apply,” or “OK” button to lock in your new setting.

Understanding the Maximum Run Time

It’s important to know that there’s usually a maximum limit to how long you can extend the remote start. Car manufacturers set these limits for a reason. They relate to engine wear, fuel efficiency, and emissions.

You won’t be able to set it to run for hours on end.

The maximum time is typically set by the vehicle’s programming. For the 2018 Chevy Suburban, this is often around 20 minutes. This extended time is still well within safe operating parameters for the engine and is designed to offer significant convenience without excessive waste.

Example: Setting Remote Start to 20 Minutes

Let’s walk through a typical scenario of extending the remote start on your 2018 Chevy Suburban to the maximum 20 minutes. First, start your Suburban and let the infotainment system boot up completely. Tap the “Home” button on your touchscreen.

Navigate to “Settings,” then select “Vehicle.” Within the vehicle settings, find and tap on “Remote Start.” You should see an option for “Engine Run Time.” Select this option. A list of choices like “10 Minutes,” “15 Minutes,” and “20 Minutes” will appear. Choose “20 Minutes.” Finally, press “Save” or “Apply” to confirm the new setting.

Your remote start will now run for the full 20 minutes.

Troubleshooting Common Issues

Sometimes, you might run into issues when trying to adjust the settings. If you can’t find the remote start option, ensure your vehicle is in Park and the parking brake is engaged. Some settings are only accessible when the vehicle is stationary.

If the option is grayed out or you receive an error message, it might be due to a system limitation or a temporary glitch. Try turning the vehicle off and on again. If the problem persists, consult your owner’s manual for specific troubleshooting steps or contact a Chevrolet dealership.

Alternative Methods If Available

While the infotainment system is the primary method for How to Extend Remote Start on 2018 Chevy Suburban, some vehicles might have alternative ways. In older models or certain trims, a dealer might need to make this adjustment using specialized diagnostic tools. However, for the 2018 model, the infotainment system is the standard approach.

It’s always a good idea to check your owner’s manual. It will confirm the exact steps for your specific vehicle configuration. The manual is the most accurate source of information.

Factors Affecting Remote Start Performance

Beyond just the settings, several things can impact how well your remote start works. We will explore these elements. Understanding them helps you get the best performance from your vehicle’s remote start system.

This ensures it’s ready when you need it.

Battery Health

The health of your vehicle’s battery is crucial for many electrical systems, including remote start. A weak battery might struggle to power the engine start sequence reliably. It can also affect the range of your key fob signal.

If you notice intermittent remote start issues or a reduced key fob range, your battery might be the culprit. Regular battery checks and maintenance are recommended, especially before extreme weather seasons. A strong battery ensures all your car’s functions operate smoothly.

Signs of a Weak Battery

A weak car battery can show several signs. You might notice the engine cranking slower than usual when you start it normally. The headlights might appear dim, especially at idle.

Warning lights on the dashboard, like the battery indicator, could also illuminate.

In cold weather, a weak battery is even more likely to fail. This is because cold temperatures reduce the battery’s capacity. If your remote start is behaving erratically, and you’re experiencing any of these symptoms, it’s wise to have your battery tested.

Testing and Replacement

You can easily test your car battery at most auto parts stores. They usually offer this service for free. They use a diagnostic tool to check the battery’s voltage and cranking amps.

If the battery is old or failing, they will recommend a replacement.

Replacing a car battery is a straightforward process. You can do it yourself with basic tools, or a mechanic can handle it quickly. Using a new, fully charged battery will ensure your remote start system functions at its best.

Key Fob Battery

The battery inside your key fob is also important. It powers the signal that communicates with your vehicle. If the key fob battery is low, you might experience a shorter range for your remote start commands.

Sometimes, the remote start might not work at all if the key fob battery is completely dead. Replacing this small battery is usually very simple and inexpensive. It’s a quick fix for remote start problems.

Replacing the Key Fob Battery

To replace the key fob battery, you’ll typically need to open the fob. This often involves a small screw or a clip. Consult your owner’s manual for specific instructions on how to open your key fob.

Once open, you’ll see the small coin-cell battery inside.

Note the battery type (e.g., CR2032) and purchase a new one. Carefully remove the old battery and insert the new one, ensuring it’s oriented correctly. Snap the fob back together.

Test the remote start again to see if the range has improved.

Environmental Conditions

Extreme temperatures can impact electronic systems. Very cold weather can affect battery performance and even the responsiveness of the key fob signal. Hot weather might also play a role, though typically less significantly.

If you live in a region with harsh winters, ensure your vehicle is properly maintained. Keeping your battery in good condition is especially important. Sometimes, just waiting a moment for electronics to adjust to the temperature can help.

Aftermarket Systems

If your 2018 Chevy Suburban has an aftermarket remote start system installed, the process for extending its run time might be different. Aftermarket systems often come with their own remotes and control modules. The method for adjustment will depend on the specific brand and model of the aftermarket system.

You would typically need to refer to the manual that came with the aftermarket kit. Sometimes, these systems have a sequence of button presses on the remote or a small programming button on the module itself that allows for setting the run time.

Consulting the Aftermarket Manual

For aftermarket systems, the installer’s manual or the manufacturer’s documentation is your best resource. These manuals will detail how to access various settings, including the engine run duration. If you don’t have the manual, you can often find a digital copy on the manufacturer’s website by searching for the product name or model number.

If you had the system professionally installed, consider contacting the installer. They can guide you through the process or make the adjustment for you. This ensures you don’t accidentally alter other settings.

Benefits of Extended Remote Start Use

Using the extended remote start feature offers several practical advantages. We will explore these benefits, showing you why it’s worth taking a few moments to adjust the settings. These perks make your driving experience more comfortable and convenient.

Enhanced Comfort and Convenience

The most obvious benefit is improved comfort. Starting your vehicle remotely and allowing it to run longer means your cabin will be at a more pleasant temperature when you get in. No more shivering in a cold car or sweating in a hot one.

This extended time is especially beneficial during long commutes or when you have multiple errands to run. You can start your car, run into a store for a longer period, and come back to a comfortable interior, without the engine having shut off prematurely.

Improved Visibility

In colder climates, extended idling time can help defrost windshields and windows more effectively. This significantly improves visibility, which is crucial for safe driving. Clear windows allow you to see the road and your surroundings better.

Allowing the engine to run for a longer duration also helps warm up the car’s systems, including the defroster. This ensures that ice and snow melt more quickly and completely. It’s a simple step that greatly enhances safety during winter months.

Protecting Your Vehicle

While modern engines are designed to handle cold starts, extended idling does allow engine components to warm up more thoroughly. This can reduce wear and tear on the engine, especially in extremely cold conditions. It ensures that all lubrication systems are working efficiently from the moment you begin driving.

Warming up the fluids also means that critical engine parts are less likely to be stressed. This gentle warming process can contribute to the longevity of your engine over time. It’s a small effort for potentially significant long-term benefits.

Examples of Extended Use Scenarios

Imagine you’re a parent preparing to take your children to school on a frosty morning. You start your 2018 Chevy Suburban with the remote start set to 20 minutes. This gives ample time for the heater to warm up the cabin, clear the windows, and make the ride comfortable for everyone.

Or consider a scenario where you’re heading out for a long road trip. You want your vehicle to be thoroughly cooled down before you pack the car and load the passengers. Setting the remote start for a longer duration ensures the air conditioning has worked its magic, making the initial departure much more pleasant.

Sample Scenario: Extended Winter Warm-Up

Let’s say it’s -10 degrees Fahrenheit outside. You’ve set your 2018 Chevy Suburban’s remote start to the maximum 20 minutes. You leave your house.

Within 10 minutes, the cabin starts to feel noticeably warmer. The windows begin to clear of frost.

You continue to get ready. By the time you walk out to your vehicle after the full 20 minutes, the ice has melted, the interior is warm, and the engine has been running long enough to circulate oil properly. You can immediately drive off safely without scraping ice or enduring extreme cold.

Sample Scenario: Extended Summer Cool-Down

During a hot summer day, you park your 2018 Chevy Suburban at the mall. The sun beats down, making the interior feel like an oven. You use the remote start, setting it for 20 minutes.

You then take your time shopping.

When you return, instead of stepping into a sweltering car, you open the door to a much cooler environment. The air conditioning has had time to circulate and lower the temperature significantly. This makes loading groceries and driving home far more enjoyable.
