KEYS AND DOORS CAUTION If the warning light comes on, observe the following instructions: D Decelerate as soon as possible to the most appropriate speed that conditions permit. D Avoid abrupt steering wheel maneuvering and braking. If the vehicle tires deteriorate, you could lose control of the steering wheel or the brakes, causing death or serious injury. If the warning light blinks and chimes sound every few minutes, the tire pressure is very low. Immediately stop your vehicle and check that the tire pressure is as specified on the tire pressure label. The air pressure gauge is located in the tool bag. Locate the deflated tire and change to the spare tire. For the procedure for changing the tire, see "If you have a flat tire (Vehicles with standard tires)" on page 241. The spare tire is not equipped with the tire pressure sensor. So, the warning light remains on even if the spare tire is mounted.
