Operation Tires and wheels Checking tire inflation pressure Regularly check your tire inflation pressure at least once a month. Check and adjust the tire inflation pressure when the tires are cold. The tires can be considered cold if the vehicle has been parked for at least 3 hours or driven less than 1 mile (1.6 km). If you check the tire inflation pressure when the tires are warm (the vehicle has been driven for several miles or sitting less than 3 hours), the reading will be approximately 4 psi (0.3 bar) higher than the cold reading. This is normal. Do not let air out to match the specified cold tire inflation pressure. Otherwise, the tire will be underinflated. Checking tire inflation pressure manually Follow the steps below to achieve correct tire inflation pressure: Remove the cap from the valve on one tire. Firmly press a tire gauge onto the valve. Read tire inflation pressure on tire gauge and check against the recommended tire inflation pressure on the placard on the driver's door B-pillar ( page 327). If necessary, add air to achieve the recommended tire inflation pressure. 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) i If you have overfilled the tire, release tire inflation pressure by pushing the metal stem of the valve with e.g. a tip of a pen. Then recheck the tire inflation pressure with the tire gauge. 329
