161 Operation
Driving instructions
After hard braking, it is advisable to drive
on for some time, rather than immediately
parking, so that the air stream will cool
down the brakes faster.Driving off
Apply the brakes to test them briefly after
driving off. Perform this procedure only
when the road is clear of other traffic.
Warm up the engine smoothly. Do not
place full load on the engine until the oper-
ating temperature has been reached.
When starting off on a slippery surface, do
not allow one drive wheel to spin for an ex-
tended 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
All checks and service work on the
brake system should be carried out by
an authorized Mercedes-Benz Center.
Install only brake pads and brake fluid
recommended by Mercedes-Benz.
Warning!
G
If other than recommended brake pads are
installed, or other than recommended brake
fluid is used, the braking properties of the
vehicle can be degraded to an extent that
safe braking is substantially impaired. This
could result in an accident.!When driving down long and steep
grades, relieve the load on the brakes
by shifting into a lower gear to use the
engine’s braking power. This helps pre-
vent overheating of the brakes and re-
duces brake pad wear.
!Simultaneously depressing the acceler-
ator pedal and applying the brake re-
duces engine performance and causes
premature brake and drivetrain wear.
Warning!
G
Do not park this vehicle in areas where com-
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:

Keep right foot on brake pedal.


Firmly depress parking brake pedal.


Move the selector lever to positionP
(manual transmission: first or reverse
gear).


Slowly release brake pedal.


When parked on an incline, turn front
wheels towards the road curb.


Turn the key to steering lock position0.


Take the key and lock vehicle when
leaving.

195 Practical hints
What to do if …?
Problem
Possible cause
Suggested solution
¿
The yellow BAS/ESP malfunction
indicator lamp comes on while
driving.
The ESP is deactivated because of an inter-
rupted power supply. The ABS may still be
operational.

With vehicle stationary and the engine
running, turn the steering wheel com-
pletely to the left and then to the right
to synchronize the ESP.
The BAS has detected a malfunction and
switched off. The brake system is still func-
tioning normally but without the BAS avail-
able.

Continue driving with added caution.

Have the system checked at an autho-
rized Mercedes-Benz Center as soon
as possible.
Failure to follow these instructions in-
creases the risk of accident.
The charging voltage has fallen below
10 volts and the BAS has switched off.

When the voltage is above this value
again, the BAS is operational again.

If necessary, have the alternator and
battery checked.

250 Practical hintsTowing the vehicleWarning!
G
Prior to towing the vehicle with all wheels on
the ground, make certain that the key is in
starter switch position2.
If the key is left in starter switch position 0
for an extended period of time, it can no
longer be turned in the switch. In this case,
the steering is locked. To unlock, remove
key from starter switch and reinsert.
If circumstances require towing the vehicle
with all wheels on the ground, always tow
with a tow bar if:

the engine will not run


there is a malfunction in the power sup-
ply or in the vehicle’s electrical system
as that will be necessary to adequately con-
trol the towed vehicle.
Warning!
G
With the engine not running, there is no
power assistance for the braking and steer-
ing systems. In this case, it is important to
keep in mind that a considerably higher de-
gree of effort is necessary to brake and
steer the vehicle. Adapt your driving accord-
ingly.iTo signal turns while being towed with
the hazard warning flasher in use, turn
key in starter switch to position2 and
activate the combination switch for the
left or right turn signal in the usual
manner – only the selected turn signal
will operate.
Upon canceling the turn signal, the haz-
ard warning flasher will operate again.
!When towing the vehicle with all wheels
on the ground, please note the follow-
ing:
With the automatic central locking acti-
vated and the key in starter switch
position2, the vehicle doors lock if the
left front wheel as well as the right rear
wheel are turning at vehicle speeds of
approx. 9 mph (15 km / h) or more.
Switch off the tow-away alarm
(page 72).
To prevent the vehicle door locks from
locking, deactivate the automatic cen-
tral locking (
page 78).
Towing of the vehicle should only be
done using the properly installed tow-
ing eye bolt. Never attach tow cable,
tow rope or tow rod to the vehicle chas-
sis, frame or suspension parts.
