Operation Tires and wheels Install the valve cap. Repeat this procedure for each tire. Run Flat Indicator* While the vehicle is being driven, the Run Flat Indicator monitors the set tire inflation pressures by evaluating each wheel's rotational speed. This allows the system to detect a significant loss of pressure in a tire. If a wheel's rotational speed changes due to falling tire inflation pressure, you will see a corresponding warning message in the multifunction display. The Run Flat Indicator may function in a restricted manner or with a delay if: snow chains are mounted to the vehicle winter road conditions prevail you are driving on a loose surface (e.g. sand or gravel) you are driving in a very sporty manner (involving rapid acceleration or high speeds in curves) Warning! G i The recommended tire inflation pressures for your vehicle can be found on the tire placard located on the driver's door B-pillar ( page 333). The tire inflation pressures are not listed in the owner's manual. When the multifunction display shows the message Low pres. mode Check tire Max. speed 50 mph, one or more of your tires is significantly under-inflated. You should stop and check your tires as soon as possible, and inflate them to the proper tire inflation pressure as indicated on the vehicle's tire information placard. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability. Each tire, including the spare, should be checked monthly when cold and set to the recommended tire inflation pressure as specified in the vehicle placard and owner's manual. 342
