Jump starting
The battery is located in the engine
compartment on the right hand side. The
terminals for jump starting are located in
front of the battery.
Make sure that the two vehicles do not
touch.
Turn off all electrical consumers.
Apply parking brake.
Shift selector lever to positionP (man-
ual transmission to Neutral).1Positive terminal of charged battery
2Positive under hood terminal in front of
discharged battery
3Negative terminal of charged battery
4Negative under hood terminal in front
of discharged battery
Connect positive terminal1 of the
charged battery with the under hood
terminal2 in front of the discharged
battery with the jumper cables. Clamp
cable to charged battery1 first.
Start engine of the vehicle with the
charged battery and run at idle speed.
Connect negative terminal3 of the
charged battery with the under hood
terminal4 of the discharged battery
with the jumper cables. Clamp cable to
charged battery3 first.
Start the engine of the disabled vehi-
cle.
Now you can again turn on the electrical
consumers. Do not turn on the lights under
any circumstances.
Remove the jumper cables first from
negative terminals3 and4 and then
from positive terminals1 and2.
Have the battery checked at the near-
est authorized Mercedes-Benz Center.
Warning!
G
Keep flames or sparks away from battery.
Do not smoke.
Observe all safety instructions and precau-
tions when handling automotive batteries
(page 240).
!Vehicles with automatic transmission
and/or 4MATIC*:
Do not tow-start the vehicle.

308 Practical hintsTowing the vehicle
Towing the vehicleMercedes-Benz recommends that the
vehicle be transported with all wheels off
the ground using flatbed or appropriate
wheel lift/dolly equipment. This method is
preferable to other types of towing.When circumstances do not permit the
recommended towing methods, the
vehicle may be towed with all wheels on
the ground or front wheels raised (except
vehicles with 4MATIC*) only so far as
necessary to have the vehicle moved to a
safe location where the recommended
towing methods can be employed.
!Use flatbed or wheel lift/dolly equip-
ment with key in starter switch turned
to position0.
Do not tow with sling-type equipment.
Towing with sling-type equipment over
bumpy roads will damage radiator and
supports.
To prevent damage during transport,
do not tie down vehicle by its chassis or
suspension parts.
Switch off the tow-away alarm
(page 80) and deactivate the auto-
matic central locking (
page 129).
!Vehicles with automatic transmission
and/or 4MATIC*:
Do not tow-start the vehicle.!Vehicles with 4MATIC*:
Do not tow with one axle raised. Doing
so could damage the transfer case,
which is not covered by the
Mercedes-Benz Limited Warranty.
All wheels must be on or off the ground.
Observe instructions for towing the
vehicle with all wheels on the ground.
!If the vehicle is towed with the front
axle raised (not permissible for vehicles
with 4MATIC*), the engine must be
shut off (key in starter switch
position0 or1). Otherwise the ESP will
immediately be engaged and will apply
the rear wheel brakes.
When towing the vehicle with all wheels
on the ground, the selector lever must
be in positionN (manual transmission:
gears disengaged) and the key must be
in starter switch position2.
When towing the vehicle with all wheels
on the ground or the front axle raised,
the vehicle may be towed only for
distances up to 30 miles (50 km) and
at a speed not to exceed 30 mph
(50 km/h).

309 Practical hints
Towing the vehicle
!To be certain to avoid a possibility of
damage to the drive train, however, we
recommend the drive shaft be discon-
nected at the rear axle drive flange
(vehicles with 4MATIC*: disconnected
at the front and rear axle drive flanges)
for any towing beyond a short tow to a
nearby garage.
Warning!
G
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
supply or in the vehicle’s electrical
system
as that will be necessary to adequately
control the towed vehicle.
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 position0
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.
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
hazard warning flasher will operate
again.

310 Practical hintsTowing the vehicleWarning!
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
degree of effort is necessary to brake and
steer the vehicle. Adapt your driving accord-
ingly.
!When towing the vehicle with all wheels
on the ground, please note the follow-
ing:
With the automatic central locking
activated 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 80).
To prevent the vehicle doors from
locking, deactivate the automatic
central locking (
page 129).
Towing of the vehicle should only be
done using the properly installed
towing eye bolt. Never attach tow
cable, tow rope or tow rod to vehicle
chassis, frame or suspension parts.
iIf the battery is disconnected or
discharged
the key will not turn in the starter
switch. See notes on the battery
(page 240) or on jump starting
(page 306).
the selector lever will remain
locked in positionP. See notes on
manual unlocking of gear selector
lever (
page 288).
