232 OperationDriving instructionsDriving off
Apply the brakes to test them briefly after
driving off. Perform this procedure only
when the road is clear of other traffic.

place full load on the engine until the
operating temperature has been reached
(page 301).
When starting off on a slippery surface, do
not allow a drive wheel to spin for an
extended period with the ESP switched off.
Doing so may cause serious damage to the
drivetrain which is not covered by the
Mercedes-Benz Limited Warranty.
Parking
!Simultaneously depressing the
accelerator pedal and applying the
brake reduces engine performance and
causes premature brake and drivetrain
wear.
!Set the parking brake whenever park-
ing or leaving the vehicle. In addition,
move gear selector lever to positionP.
When parking on hills, always turn front
wheels towards the road curb.
Warning!
G

bustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.
To reduce the risk of personal injury as a re-
sult of vehicle movement, before turning off
the engine and leaving the vehicle always:

Warning!
G
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious
injury. Whenever you are around gasoline,
avoid inhaling fumes and skin contact,
extinguish all smoking materials. Never
allow sparks, flame or smoking materials
near gasoline!

with a minimum Posted Octane Rating
of 91 (average of 96 RON/86 MON).
Information on gasoline quality can
normally be found on the fuel pump.Warning!
G
Overfilling of the fuel tank may create
pressure in the system which could cause a
gas discharge. This could cause the gas to
spray back out when removing the fuel
pump nozzle, which could cause personal
injury.

246 OperationEngine compartmentClosing
Pull the hood upwards in the center,
against the resistance of the gas-filled
spring struts.

Hold the front center part of the hood
with both hands and push it back-
wards. After pushing the hood back-
wards about half-way, you will feel the
hood passing a crest and the resulting
force pulling the hood away from you.
At that point, let go of the hood and let
it fall onto the latches.
The hood should now be locked and en-
tirely closed.

Check that the hood is properly closed.
If the hood is not properly engaged, re-
peat the closing procedure.
Engine oil
The amount of oil your engine needs will
depend on a number of factors, including
driving style. Higher oil consumption can
occur when

the vehicle is new


the vehicle is driven frequently at
higher engine speeds
Engine oil consumption checks should only
be made after the vehicle break-in period.
Regularly check the engine oil level, at
least every 1 800 miles (3 000 km).
Warning!
G
Be careful that you do not close the hood on
anyone.
!Make sure the rollers at the rear of the
hood are engaged and the guide pins
line up with the guide holes. Otherwise
the hood may be damaged.
!Do not use any special lubricant addi-
tives, as these may damage the drive
assemblies. Using special additives not
approved by Mercedes-Benz may
cause damage not covered by the
Mercedes-Benz Limited Warranty.

Suggested solutions
-
The yellow ABS indicator
lamp comes on while driving.
The ABS has detected a malfunction and
has switched off. The BAS and the ESP are
also switched off (see messages in dis-
play).
The SBC brake system is still functioning
normally but without ABS available.
If the ABS control unit is malfunctioning
the automatic transmission may also be
malfunctioning.

Continue driving with added caution. Wheels
may lock during hard braking, reducing
steering capability.

Read and observe messages in the display
(page 304).

Have the system checked at an authorized
Mercedes-Benz Center immediately.
Failure to follow these instructions increases
the risk of an accident.
The charging voltage has fallen below
10 volts and the ABS was switched off.
When the voltage is above this value again, the
ABS is operational again.
If necessary, have the generator and battery
checked.
