Checking using tire inflation
pressure specifications in the tire
inflation pressure table
The tire inflation pressure specifications in the
tire inflation pressure table only relate to cold
tires or tires at the same temperature as the am‐
bient temperature.
Only check the tire inflation pressure levels when
the tires are cold, i.e.:
▷ Driving range of max. 1.25 miles/2 km has not
been exceeded.
▷ If the vehicle has not moved again for at least
2 hours after a trip.
Check the tire inflation pressure of the emer‐
gency wheel in the cargo area regularly, and cor‐
rect it as needed.
1. Determine, refer to page 252 , 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 cur‐
rent tire inflation pressure value deviates from
the specified value.
4. Check whether all valve caps are screwed
onto the tire valves.
Checking using the tire inflation
pressure specifications on the
Control Display
Via iDrive:
1. "CAR"
2. "Vehicle status"
3. "Tire Pressure Monitor"
4. Check whether the current tire inflation pres‐
sure levels deviate from the intended tire
pressure value.
5. Correct the tire inflation pressure if the cur‐
rent tire inflation pressure value deviates from
the intended value.
After correcting the tire inflation
pressure
With runflat tires:
Reinitialize the Flat Tire Monitor.
With Tire Pressure Monitor TPM:
The corrected tire inflation pressures are applied
automatically. Make sure that the correct tire set‐
tings have been made.
With tires that cannot be found in the tire pres‐
sure values on the Control Display, reset the Tire
Pressure Monitor TPM.
Tire inflation pressures up to
100 mph/160 km/h
For speeds of up to 100 mph/160 km/h and for
optimum driving comfort, note the pressure val‐
ues in the tire inflation pressure table, refer to
page
254 , and adjust as necessary.
These pressure values can also be found on the
tire inflation pressure label on the driver's door
pillar.
Do not exceed a speed of 100 mph/160 km/h.
