	Checking
1	Check tire pressure on all wheel-and-tire assemblies, correct if necessary	Obtain the required tire pressures from the tire pressures of the tire pressure chart on the fuel filler flap or in the operator's manual. The tire pressure changes as tire pressure temperature changes for every 10°C by approx. 0.1 bar. Take this into consideration when checking the tire pressure in workshops - especially in winter when tires on a vehicle that has been inside the workshop for a long time will have warmed to room temperature.
2	Remove spare tire cover and check tire pressure of spare wheel; correct if necessary	Correct the tire pressure of the spare wheel to the highest tire pressure specified for the vehicle.
3	Fit spare tire cover
