General
information
The tire characteristics and tire inflation presj
sure influence the following:'yThe service life of the tires.'yRoad safety.'yDriving comfort.'yFuel consumption.
Safety
information
WARNING
A tire with too little or no tire inflation
pressure may heat up significantly and sustain
damage. This will have a negative impact on aspects of handling, such as steering andbraking response. There is a risk of an accij
dent. Regularly check the tire inflation presj
sure, and correct it as needed, for instance
twice a month and before a long trip.'

Only check the tire inflation pressure levels
when the tires are cold, i.e.:'yDriving range of max. 1.25 miles/2 km has not been exceeded.'yIf the vehicle has not moved again for at
least 2 hours after a trip.
Check the tire inflation pressure of the emerj
gency wheel in the cargo area regularly, and
correct it as needed.
1.Determine, refer to page 268, the intended
tire inflation pressure levels for the
mounted tires.2.Check the tire inflation pressure in all four tires, using a pressure gage, for example.3.Correct the tire inflation pressure if the curjrent tire inflation pressure value deviates
from the specified value.4.Check whether all valve caps are screwed onto the tire valves.

These pressure values can also be found on
the tire inflation pressure label on the driver's
