Checkingthe vehicle height
G
WARNING
Whenyou drive with the chassislowered or
raised,the vehicle's braking and driving
characteristics can be significantly impaired.
Youcould also exceed the permissiblevehi-
cle height if the chassisisraised. There is a
riskofanaccident.
Adjust the vehiclelevel before pulling away.
X
Vehicles with level control: set the driving
level (Y page 142).

cluster goesout.
Pulling away
!
Do not pull away during the first engine
rotations. After starting the engine,allow it
to runinidlefor ashort time,untilsufficient
oilpressure hasbeenattained. Do not run
the coldengine at high engine speeds.
In thisway,you will avoidincreased wear
and possibleengine damage.
