Block the wheels standing on the ground, use rigid wooden blocks or large stones. The jack should be kept well-greased and clean, and should not be damaged. No objects should be placed between the base of jack and the ground, or between the jack and the attachment bar on the vehicle. Installing the wheel 1. Clean the contact surfaces on the wheel and hub. 2. Lift the wheel and place it on the hub. 3. Install the wheel nuts and tighten hand-tight. Using the lug wrench, tighten crosswise until all nuts are snug. 4. Lower the vehicle to the ground and alternately tighten the bolts crosswise to 96 ft. lbs. (130 Nm). 5. Install the wheel cap (where applicable). 184 07 Wheels and tires Tire Pressure Monitoring System (TPMS) Introduction The tire pressure monitoring system uses sensors mounted in the tire valves to check inflation pressure levels. When the vehicle is moving at a speed of approximately 20 mph (30 km/h) or faster, these sensors transmit inflation pressure data to a receiver located in the vehicle. NOTE USA - FCC ID: KR5S122780002 This device complies with part 15 of the FCC rules. Operation is subject to the following conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. When low inflation pressure is detected, TPMS will light up the tire pressure warning light ( ) (also referred to as a telltale) in the instrument panel, and will display a message in the text window. The wording of this message is determined by the degree of inflation pressure loss. NOTE If a fault occurs in TPMS, the tire pressure warning light will flash for approximately 1 minute and TIRE PRESS SYST SERVICE REQUIRED will be displayed. Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly under-inflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to
