Steps to Reset Genesis GV70 Tire Pressure Light
Step 1: Check and Adjust Your GV70's Tire Pressure
The Genesis GV70 doesn’t come with a dedicated button to reset the tire pressure. To turn off the tire light, you’ll need to ensure that all four of your tires are filled to the proper pressure levels. To find the correct pressure, you can look at the sticker on the inside of the driver’s side door frame, refer to the chart below, or use the Mode button on your steering wheel to navigate to the tire pressure display. Make sure you fill each tire to the exact recommended pressure. It’s important to adjust your tire pressure only when the tires are cold, meaning they haven’t built up heat yet. This is usually before embarking on long drives or after your car has been parked for a couple of hours.
Step 2: Drive Your GV70
Once you’ve filled your tires to the suggested cold pressure, go ahead and take your GV70 for a spin. Drive for a few minutes at speeds over 20 mph. You might see a message saying “drive to display.” As you continue driving, the tire pressure light should turn off. If it doesn’t disappear immediately, just keep on driving a bit longer.
Step 3: Re-Check Your Tire Pressure
If the tire pressure light remains on after following steps 1 and 2, double-check your tire pressure to ensure they’re still at the precise level you set them to. If there not, there might be a leak in the tire or valve stem, or perhaps a puncture. In case the tire light turns off after inflating the tires but then comes back on, you most likely have a tire leak. If the tire pressure light blinks or flashes before staying on, it indicates that your tire pressure system is malfunctioning.

Genesis GV70 TPMS Malfunction Indicator
The tire pressure monitoring system (TPMS) in the Genesis GV70 has a built-in malfunction indicator. This indicator uses the same yellow exclamation point tire warning light as the low pressure warning. If the TPMS experiences an issue, the warning light (yellow exclamation point) will flash for around a minute before staying on. This flashing sequence will continue every time you start your car until the problem is fixed.
It’s crucial to understand that while the indicator is active, the TPMS may not work correctly, which means your tire pressure monitoring system won’t function as it should until the TPMS issue is resolved. In other words, if your tire pressure light is blinking, it signifies a problem with the TPMS itself, typically a faulty pressure sensor in one of your tires, rather than an actual air pressure concern.
To identify which tire sensor is causing the trouble, you’ll need a TPMS diagnostic tool, like the Autel TPMS tool. (I’ve been using Autel TPMS diagnostic tools for a few years, and I can’t recommend them enough.)
Reset your TPMS in These Cases:
After adjusting tire pressure to the recommended levels
During tire rotation or tire replacement (keep in mind that many Genesis GV70s have staggered wheels and tires, with different sizes for the front and rear; if your GV70 has staggered tires, avoid rotating them front to back)
When a TPMS sensor has been replaced or serviced
After putting on a new wheel or changing tire size
If the vehicle’s battery has been disconnected or swapped out
When the TPMS malfunction indicator is activated
Seasonal shifts that could impact tire pressure due to changes in temperature
How the Genesis GV70 TPMS Works
The Genesis GV70’s tire pressure monitoring system (TPMS) is designed to ensure optimal tire pressure, enhancing safety and fuel efficiency. Here’s a detailed breakdown of how it works:
Direct TPMS: The Genesis GV70 uses a direct TPMS, which means it has pressure sensors located inside each tire that continuously monitor tire pressure levels.
Wireless Transmission: These sensors wirelessly transmit tire pressure data to the vehicle’s onboard computer, allowing for real-time monitoring.
Tire Pressure Display: The TPMS data can be accessed through the vehicle’s display system, providing you with the current tire pressure of each tire.
Low Pressure Warning: If any tire’s pressure falls below the recommended level, the TPMS will trigger a warning light (a yellow exclamation point) on the dashboard to alert the driver.
Malfunction Indicator: The TPMS also has a built-in malfunction indicator that uses the same warning light. If the system encounters a problem, the light will flash for about a minute and then remain on. This pattern will repeat each time you start your car until the issue is resolved.
Sensor Battery Life: The TPMS sensors are battery-powered and typically last around 5-10 years. When the battery runs low or fails, it will trigger the malfunction indicator.
Seasonal Changes: The TPMS can help identify significant changes in tire pressure due to seasonal temperature fluctuations, ensuring that tires remain at optimal pressure levels throughout the year.
What Causes Your TPMS Light to Turn On?
The Genesis GV70 TPMS light can come on for various reasons, signaling potential issues that need to be addressed. Here’s a comprehensive list of causes:
Low Tire Pressure: The most common reason for the TPMS light to come on is when one or more tires have pressure below the recommended level. This can result from a slow leak, puncture, or natural pressure loss over time.
TPMS Malfunction: If the TPMS itself is experiencing a problem, the warning light will flash for about a minute and then stay lit. This could be due to a faulty sensor, a dead or dying sensor battery, or communication issues between the sensor and the vehicle’s computer.
Seasonal Changes: Fluctuations in temperature can cause changes in tire pressure. Cold weather often leads to a decrease in tire pressure, while warmer temperatures can result in increased pressure. The TPMS light will come on when significant pressure changes occur due to seasonal temperature shifts. (read more on this below)
Tire Rotation or Replacement: The TPMS light might come on after a tire rotation or replacement if the system needs to be reset or if the tires have not been inflated to the proper pressure.
New Wheel or Tire Size Installation: If you have installed new wheels or changed tire sizes, the TPMS light could come on if the system has not been recalibrated to account for the changes. This will also be a problem if you replace a wheel/rim and don’t swap sensors over from old wheel to new wheel.
Disconnected or Replaced Vehicle Battery: The TPMS light might be triggered if the vehicle’s battery has been disconnected or replaced, as this may require the system to be reset.
Sensor Damage: Physical damage to a TPMS sensor, such as from an impact, corrosion, or improper installation, can cause the TPMS light to come on. I have seen many times, the rubber gasket in between the valve and sensor goes bad, causing a leak. The rubber gasket is replaceable without having to replace the entire sensor.
How Air Temperature Affects Tire Pressure
The graph above shows us how air temperature affects tire pressure. What it shows is that when it gets colder outside, tire pressure tends to decrease, and when it gets warmer, tire pressure goes up. A good reference point to keep in mind is around 62°F (16.7°C), as that’s the temperature where tire pressure generally stays stable. So, for every 10-degree drop in air temperature, your tire pressure will go down by about 1 PSI.
Benefits of TPMS in the Genesis GV70
Safety: By constantly monitoring tire pressure, the TPMS helps maintain optimal tire performance and grip, reducing the risk of tire-related accidents caused by underinflation.
Fuel Efficiency: Properly inflated tires ensure better fuel efficiency, and the GV70’s TPMS helps you maintain the correct tire pressure, saving you money on gas in the long run.
Prolonged Tire Life: Tires with the right pressure levels experience more even tread wear and have a longer lifespan. The TPMS alerts you to pressure discrepancies, enabling you to address them before they lead to premature tire wear.
Real-Time Monitoring: The GV70’s TPMS provides real-time pressure data for each tire, making it easy for you to keep an eye on your tire health and make adjustments as needed.
Convenience: The TPMS eliminates the need for regular manual tire pressure checks, as it will alert you when there is a significant drop in pressure or a malfunction in the system.
Seasonal Adaptability: The TPMS helps you stay on top of tire pressure changes caused by temperature fluctuations during seasonal transitions, ensuring optimal tire performance throughout the year.
Overall, the Genesis GV70 TPMS contributes to a safer, more efficient, and convenient driving experience by maintaining proper tire pressure and alerting you to potential issues.
