Operation Tires and wheels 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 336). If necessary, add air to achieve the recommended tire inflation pressure. Run Flat Indicator (Canada only) 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 in winter road conditions prevail in presence of ice and snow if you are driving on a loose surface (e.g. sand or gravel) if you are driving in a very sporty manner (involving rapid acceleration or high speeds in curves) Warning! G Follow recommend tire inflation pressures. Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely affect handling and fuel economy, and are more likely to fail from being overheated. Do not overinflate tires. Overinflated tires can adversely affect handling and ride comfort, wear unevenly, increase stopping distance, and result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road debris, potholes etc. Do not overload the tires by exceeding the specified load limit or vehicle capacity weight as indicated on the placard on the driver's door B-pillar. Overloading the tires can overheat them, possibly causing a blowout. 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. Install the valve cap. Repeat this procedure for each tire. 343
