Common Reasons for the TPMS Light to Activate

Before resetting the TPMS light, it’s crucial to understand what might be causing it to turn on in the first place. Here are some common reasons:

Low tire pressure: The most obvious reason for the TPMS light to activate is under-inflation of one or more tires.
Seasonal temperature changes: As the weather cools or warms, tire pressure can fluctuate, causing the TPMS to trigger.
Faulty tire sensors: Sometimes, the sensors themselves malfunction and send a false signal to the dashboard.
Tire rotation or replacement: After rotating your tires or replacing one, the system might not immediately recalibrate itself.

FAQs about TPMS in Lexus RX

Why won’t my TPMS light turn off?

If your TPMS light stays on, it could be due to a malfunctioning sensor, or you may not have inflated your tires to the correct pressure. Double-check the pressure and consult a mechanic if needed.

How often should I check my tire pressure?

You should check your tire pressure monthly or before long trips. Tires can lose pressure gradually over time, and fluctuating temperatures can affect their pressure as well.

Can I drive with the TPMS light on?

While you can technically drive with the TPMS light on, it’s not recommended. The light could indicate a serious issue with your tires that could lead to unsafe driving conditions.

What if my Lexus RX doesn’t have a TPMS reset button?

Some Lexus models don’t have a reset button, meaning you’ll need to rely on adjusting tire pressure or seek help from a professional mechanic.

Can cold weather affect my TPMS light?

Yes, cold weather can cause tire pressure to drop, which might trigger the TPMS light. Be sure to adjust tire pressure when the seasons change.
