Important!
A discharged battery can freeze at approx. +14
°F
(–10
°C). In that case, it must be thawed out before
jumper cables are used. Attempting to jump start a
frozen battery can result in it exploding, causing
personal injury.
Jumper cable specifications:
•Minimum cable cross-section of 25 mm
2 or approx.
2AWG
•Maximum length of 11.5 ft. (3.5 m).
If the battery is discharged, the engine should be started
with jumper cables and the (12 V) battery of another
vehicle.
Only use 12 V battery to jump start your vehicle. Jump
starting with more powerful battery could damage the
vehicle’s electrical systems, which will not be covered
by the Mercedes-Benz Limited Warranty.
The battery is located in the trunk under the trunk floor.Proceed as follows:
1. Position the vehicle with the charged battery so that
the jumper cables will reach, but never let the
vehicles touch. Make sure the jumper cables do not
have loose or missing insulation.
2. On both vehicles:
•Turn off engine and all lights and accessories,
except hazard warning flashers or work lights.
•Apply parking brake and shift selector lever to
position “P”.
Important!
3. Clamp one end of the first jumper cable to the
positive (+) terminal of the discharged battery and
the other end to the positive (+) terminal of the
charged battery. Make sure the cable clamps do not
touch any other metal parts.
4. Clamp one end of the second jumper cable to the
grounded negative (–) terminal of the charged
battery and the final connection to the negative (–)
terminal (2) of the discharged battery.

5. Start engine of the vehicle with the charged battery
and run at high idle. Make sure the cables are not
on or near pulleys, fans, or other parts that move
when the engine is started. Allow the discharged
battery to charge for a few minutes. Start engine of
the disabled vehicle in the usual manner.
6. After the engine has started, remove jumper cables
by exactly reversing the above installation
sequence, starting with the last connection made
first. When removing each clamp, make sure that it
does not touch any other metal while the other end
is still attached to a battery.
Notes:
If engine does not run after several unsuccessful
starting attempts, have it checked at the nearest
authorized Mercedes-Benz Center.
Excessive unburned fuel generated by repeated failed
starting attempts may damage the catalytic converter.Tow i n g t h e v e h i c l e
Mercedes-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.
Caution!
Use flatbed or wheel lift/ dolly equipment with key in
steering lock turned to position 0.
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 (see page 40) as well as
the ESP (see page 218).
When circumstances do not permit the recommended
towing methods, the vehicle may be towed with all
wheels on the ground or front wheels raised only so far
as necessary to have the vehicle moved to a safe location
where the recommended towing methods can be
employed.

Caution!
If the vehicle is towed with the front axle raised, the
engine must be shut off (electronic key in steering lock
in position 0 or 1). Otherwise, the EPS 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 position “N” and the key
must be in steering lock position 2.
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).
To be certain to avoid a possibility of damage to the
drivetrain, however, we recommend the drive shaft be
disconnected at the rear axle drive flange for any towing
beyond a short tow to a nearby garage.
Important!
When towing the vehicle with all wheels on the ground,
please note the following:
Wa r n i n 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 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 electronic key is in
steering lock position 2.If the key is left in the steering lock position 0 for
an extended period of time, it can no longer be
turned in the lock. In this case, the steering is
locked. To unlock, remove electronic key from
steering lock and reinsert.

electronic key in steering lock position 2, 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. To prevent the vehicle doors from
locking, deactivate the automatic central locking, see
page 34.
Note:
To signal turns while being towed with hazard warning
flasher in use, turn electronic key in steering lock to
position 2 and activate combination switch for left or
right turn signal in usual manner – only the selected
turn signal will operate.
Upon canceling the turn signal, the hazard warning
flasher will operate again.The rear towing eye is located at the right, below the
bumper. The front towing eye is located on the
passenger side behind a cover in the bumper panel.

Wa r n i n g !
With the engine not running, there is no power
assistance for the braking and steering 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.

For safety reasons, remove electronic key from steering
lock before replacing the wiper blade, otherwise the
motor can suddenly turn on and cause injury.

Engine cleaning
Prior to cleaning the engine compartment make sure to
protect electrical components and connectors from the
intrusion of water and cleaning agents.
Corrosion protection, such as MB Anticorrosion Wax
should be applied to the engine compartment after
every engine cleaning. Before applying, all control
linkage bushings and joints should be lubricated. The
poly-V-belt and all pulleys should be protected from any
wax.
Ta r sta in s
Quickly remove tar stains before they dry and become
more difficult to remove. A tar remover is
recommended.Ve h i c l e w a s h i n g
Do not use hot water or wash your vehicle in direct
sunlight. Use only a mild car wash detergent, such as
Mercedes-Benz approved Car Shampoo.
Thoroughly spray the vehicle with a diffused jet of
water. Direct only a very weak spray towards the
ventilation intake. Use plenty of water and rinse the
sponge and chamois frequently.
Rinse with clear water and thoroughly wipe dry with a
chamois. Do not allow cleaning agents to dry on the
finish.
In the winter, thoroughly remove all traces of road salt
as soon as possible.
When washing the underbody, do not forget to clean the
inner sides of the wheels.
Ornamental moldings
For regular cleaning and care of very dirty chrome-
plated parts, use a chrome cleaner.
