Tire Pressure Warning Light
IF YOUR LIGHT COMES ON
First things first, check all four tires for nails, tears or any damage that might cause it to lose pressure.
Next, use a tire pressure gauge on the tire (or tires) that your system indicated had low pressure.
Compare the tire’s psi with the manufacturer’s recommended psi, which can be found in your owner’s manual or on the sticker inside of your driver’s side door jam. (To find this sticker, click here.)
If pressure is low, add air until it reaches the proper pressure.
If your light continues to stay on, take your vehicle to an authorized tire dealer immediately.

FAQ
A yellow or amber symbol shaped like a horseshoe or a cross-section of a tire, with an exclamation mark in the centre, on your instrument cluster. Some vehicles also show per-tire pressure readouts in the driver information display, which tells you exactly which tire is low.
Air contracts as temperature drops, so a tire inflated correctly in warm weather reads lower on a cold morning. This is the single most common reason the light appears in Canada, usually with the first hard cold snap of the season. It is a real pressure drop, not a false alarm, and it needs correcting to the placard figure.
Check all four tires with a gauge as soon as you can safely do so. Add air to any tire below the placard pressure. Then drive a short distance to let the system re-read. If the light stays on after correcting pressure, or if a tire shows visible damage, get to a dealer immediately or call roadside assistance.
Only far enough to reach a safe place to check or add air. The light means at least one tire is significantly below specification, which affects handling and braking and risks heat-related failure at speed. Drive at reduced speed, avoid highway travel, and address it as soon as possible.
Not necessarily. It can be natural pressure loss, a cold weather drop, a leaking valve stem, or a slow puncture. If the tire keeps losing pressure after you refill it, that is an actual leak needing professional inspection. If it holds after refilling, it was likely natural loss or temperature-related.
No. TPMS typically only triggers when pressure has dropped well below specification, often around 25 percent low. A tire can be meaningfully underinflated, hurting fuel economy, handling, and tread life, without ever lighting the warning. Monthly manual checks catch what the system does not.
