⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is securely lifted and supported when working on tires.
•Use caution when inflating tires to avoid over-inflation.

Symptoms

•"Low tire pressure" warning light illuminated on the dashboard
•Tire pressure readings below recommended levels in the vehicle display
•Uneven tire wear or visible damage on tires
•Vehicle handling issues such as pulling to one side
•Decreased fuel efficiency or range

Diagnostic Steps

1
Check the tire pressure using a tire pressure gauge to confirm readings.
2
Inspect each tire visually for signs of damage, punctures, or foreign objects.
3
Verify that the tire pressure monitoring system (TPMS) is functioning correctly by checking if the warning resets after adjusting tire pressures.
4
Examine the valve stems for leaks or damage.
5
Consult the vehicle's manual for the recommended tire pressure specifications.

Solution

Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor, tire repair kit (if needed), and a jack.
Ensure the vehicle is parked on a flat surface and the tires are cold for accurate pressure readings.

2. Check and Adjust Tire Pressure

Sub-steps:
1. Use the tire pressure gauge to measure the pressure of each tire.
2. Refer to the vehicle's manual or the sticker located on the driver's door jamb for the recommended tire pressure.
3. If any tire is under-inflated, use an air compressor to inflate it to the correct pressure.
4. If the tire pressure is above the recommended level, release some air until it reaches the desired pressure.

3. Inspect for Damage

Sub-steps:
1. Visually inspect each tire for cuts, punctures, or bulges.
2. If any damage is found, consider repairing the tire with a patch or replacing it as necessary.
3. Check for any foreign objects lodged in the tread that could cause a slow leak.

4. Reset TPMS (if applicable)

Sub-steps:
1. After adjusting the tire pressures, navigate to the vehicle settings on the touchscreen.
2. Select the option for resetting the TPMS.
3. Follow the prompts to complete the reset process.
