Functional requirements
Only check the tire pressure when the tires
are cold, i.e.:
– Vehicle has not exceeded a distance
traveled of max. 1.25 miles/2 km.
– If the vehicle has not moved again for at
least two hours after a trip.
Checking via tire pressure
specifications in tire pressure table
To check the tire pressure using the tire
pressure specifications in the tire pressure
table, proceed as follows:
1. Determine the nominal tire pressure for
your tires using the information on the
door pillar in the driver’s door.
2. Check the tire inflation pressure in all
four tires, using a pressure gage, for ex-
ample.
3. Correct the tire inflation pressure if the
actual tire inflation pressure deviates
from the intended tire inflation pres-
sure.
4. Make sure that all valve caps are
screwed onto the tire valves.
The tire pressures specified in the tire pres-
sure table only correspond to cold tires or
tires at ambient temperature.
If vehicle is equipped with an emergency
wheel: Check the tire pressure of the emer-
gency wheel in the cargo area regularly and
correct as necessary.
Checking tire pressure specifications
on Interaction Unit
To check the tire pressure using the tire
pressure information on the Interaction
Unit, proceed as follows:
1. Go through the menu as follows: Apps
menu / "Vehicle" / "Vehicle status" /
"Tire Pressure Monitor".
2. Check whether the current tire infla-
tion pressure levels deviate from the in-
tended tire pressure value.
3. Correct the tire inflation pressure if the
actual tire inflation pressure deviates
from the intended tire inflation pres-
sure.
The Interaction Unit may not be able to dis-
play current tire pressures when the vehicle
is stationary. The tire pressure will update
after a short drive.
After correcting the tire pressure
If your vehicle is equipped with a Tire Pres-
sure Monitor, the corrected tire pressures
are applied automatically. Make sure that
the tire settings are correct. When using
tires not listed in the tire inflation pressure
specifications on the Interaction Unit, reset
the Tire Pressure Monitor.
If your vehicle is equipped with the Flat
Tire Monitor, reinitialize it.
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, follow the tire
inflation pressure specifications in the tire
pressure table and adjust as necessary.
