The Tire Pressure Monitoring System is configured at the factory with the correct tire inflation pres-sure applicable for the vehicle model, engine and factory-installed tires. The tire inflation pressure is listed on the tire inflation pressure label on the driver door jamb. The tire inflation pressures for the road tires are listed on this label. The inflation pressure for the compact spare is as specified on the tire pressure label or on a separate label for the compact spare, if there is one. In the event of a discrepancy between the above figures and the tire pressures listed on the tire inflation pressure label, the pressures listed on the label are the ones you should use. The listed pressure applies to all road tires. The Tire Pressure Monitoring System must be recalibrated using the SET button whenev-er you change or adjust the cold tire inflation pressures or remove and remount or change any wheel or tire on the vehicle, even if the reinstalled or replacement wheels and tires are identical to those that were removed and even if the tire pressure does not change.

Tread depth and tread wear indicators

Fig. 102 Tread pattern: Wear indicator.

In most countries the legally permissible minimum tread depth is 1/16 in. (1.6 mm), as measured in tread grooves next to the wear indicators. Please be sure to obey country-specific legal requirements.
Winter tires are no longer suitable for winter operation once the tread pattern is worn down to a depth of 3/16 in. (4.8 mm).
The tread depth of new tires can differ between tire models and manufacturers because of the differ-ent design features and tread patterns.
Tread wear indicator (TWI) in the tire
The 1/16 in. (1.6 mm) high wear indicators are molded into the bottom of the tread grooves of the
original tires running across the treads ⇒ fig. 102. Several wear indicators are evenly spaced around the tire. Markings on the sides of the tires (for example “TWI” or symbols) show the position of the wear indicators.
Wear indicators show when the tires are worn down. The tires must be replaced no later than when the tread pattern is worn down to the wear indicators.
WARNING
Worn tires are dangerous and can cause loss of vehicle control including serious personal injuries.
x Never drive a vehicle when the tread on any tire is worn down to the wear indicators, re-place them sooner.
x Worn tires do not grip the road properly, especially on wet roads, increasing your risk of “hydroplaning” and loss of control.
x Worn tires reduce the ability of your vehicle to handle well in normal and difficult driving situations and increase braking distances and the risk of skidding.
Tire wear and damage

WARNING
Improper use of a compact spare wheel can cause loss of vehicle control, a crash or other accident, and serious personal injury.
x Never use a compact spare wheel if it is damaged or worn down to the wear indicators.
x In some vehicles, the compact spare wheel is smaller than the original tire. A smaller compact spare wheel is identified with a sticker and the words “50 mph” or “80 km/h”. This is the maximum permissible speed when driving with this tire.
x Never drive faster than 50 mph (80 km/h) with a compact spare wheel. Avoid full-throttle acceleration, heavy braking, and fast cornering!
x Never drive more than 125 miles (200 km) if a compact spare wheel is installed on the front axle (drive axle).
x Replace the compact spare with a normal wheel and tire as soon as possible. Compact spare tires are designed for brief use only.
x Regularly check the U.S. DOT Tire Identification Number (TIN) to determine the age of the
compact spare wheel ⇒  Tire labeling. Tires age even if they are not being used and can fail suddenly, especially at higher speeds.
x Tires that are more than 6 years old can only be used in an emergency and then with spe-cial care and at lower speeds.
x The compact spare wheel must always be secured with the wheel bolts provided by the factory.
x Never drive using more than one compact spare wheel.
x After installing the compact spare wheel, the tire pressure must be checked as soon as
possible ⇒  Tire inflation pressure.
x Snow chains cannot be used on the compact spare wheel. If you must use snow chains and have a compact spare wheel mounted, move the compact spare wheel to the rear axle if a front tire has to be replaced. The tire taken off the rear axle can then be used to replace the flat front tire. Be sure you do not change the tire's direction of rotation. Install the snow chains on the full-sized road tire.
NOTICE
When the compact spare is being used, the TPMS indicator light can come on after a couple of
minutes ⇒  Tire Pressure Monitoring System (TPMS).
If possible, attach the compact spare wheel or the wheel you took off the vehicle securely in the luggage compartment.

Section width
The linear distance between the exteriors of the sidewalls of an inflated tire, excluding elevations due to labeling decoration, or protective bands.
Sidewall
The portion of a tire between the bead and the tread.
Sidewall separation
The parting of the rubber compound from the cord material in the sidewall.
Speed rating (letter code)
A standardized letter code indicating the maximum speed at which a tire is designed to be driven for extended periods of time. The ratings range from 93 mph or 150 km/h (“P”) to 186 mph or (300 km/h) “Y”.
The speed rating letter code, where applicable, is molded on the tire sidewall. You may not find this information on all tires because it is not required by law.
Tire Pressure Monitoring System
A system that detects when at least one of a vehicle's tires is underinflated and illuminates a low tire-pressure warning light.
Tread
The portion of a tire that normally touches the road.
Tread rib
A tread section running circumferentially around a tire.
Tread separation
Tire failure caused by the tread pulling away from the tire carcass.
Tread wear indicators (TWI)
Raised areas within the main tread grooves that show, visually, when tires are worn and near the end of their useful life.
Uniform Tire Quality Grading (UTQG)
A tire information system developed by the U.S. National Highway Traffic Safety Administration (NHTSA) that is designed to help buyers compare tires. UTQG is not a safety rating, nor is it a guaran-tee that a tire will last for a certain number of miles or perform a certain way. It gives tire buyers more information to compare with factors such as price, brand loyalty and dealer recommendations. Under UTQG, tires are graded by the tire manufacturers in 3 areas: tread wear, traction and temperature resistance. UTQG information is molded into the tire sidewalls.
U.S. DOT Tire Identification Number (TIN)
A tire's serial number. It begins with the letters “DOT” (“Department of Transportation”) and indicates that the tire meets all federal standards. The next 2 numbers or letters indicate the plant where the tire was manufactured. The last 4 numbers represent the week and year of manufacture.
For example, the numbers 1709 mean that the tire was produced in the 17th week of 2009. Any other numbers are marketing codes used by the tire manufacturer. This information is used to help identify affected consumers if a tire defect requires a recall.
Vehicle capacity weight
The total rated cargo, luggage and passenger load. Passenger load is 150 lbs (68 kilograms) times the vehicle's total seating capacity (as listed on the label inside the driver door).

mirror A informs you about traffic to the left, and the indicator light in the passenger side outside mirror B informs you about traffic to the right of your vehicle.
Tinting on the side windows or aftermarket tinting films can interfere with the indicator lights in the outside mirrors or cause false readings.
Keep the glass in the outside mirrors clean and free of snow and ice, and do not cover the mirrors with stickers or other objects.
Radar sensors
The radar sensors are behind the rear bumper on the left and right ⇒ fig. 143. They are not visible from outside the vehicle. They monitor an area about 21 yards (20 meters) behind the vehicle as well as the blind spots on the left and right sides of the vehicle. The monitored area next to the vehicle is about one lane wide.
The width of the lane is not detected individually on each road, but is preprogrammed into the system. Because of this, the indicators may be incorrect when driving on narrow roads or driving in the center of two lanes. Likewise, vehicles that are two lanes away from you or stationary objects such as guard rails may also be detected and cause a false warning.
