Battery
324 Battery acid is caustic.
Avoid contact with the
skin, eyes or clothing.
Wear suitable protective
clothing, in particular
gloves, an apron and a
face mask.
Immediately rinse acid
splashes off with clean
water. Consult a doctor if
necessary.
Wear eye protection.
Keep children away.
Observe this Owner's
Manual.
H
Environmental note
Do not dispose of batteries with the house-
hold rubbish. Dispose of defective batteries
in an environmentally responsible manner.
Take them to a Mercedes-Benz Service Centre or to a special collection point for
old batteries.
G
Risk of injury
For safety reasons, Mercedes-Benz recom-
mends that you only use batteries which
have been tested and approved for your
vehicle by Mercedes-Benz. These batteries
provide increased impact protection to pre-
vent vehicle occupants from suffering acid
burns should the battery be damaged in the
event of an accident.
To prevent acid burns, observe the follow-
ing safety notes when handling batteries:
R Do not lean over batteries.
R Do not place any metal objects on a bat-
tery. You could otherwise cause a short
circuit and the battery's highly flammable
gas mixture could ignite.
R Make sure that you do not create an elec-
trostatic charge, e.g. by wearing syn-
thetic clothing or as a result of friction on
fabrics. Therefore, you should not pull or
slide the battery over carpets or other
synthetic materials.
R Never touch the battery first. To dis-
charge a possible electrostatic charge, step out of the vehicle first and touch the
bodywork.
R Do not wipe the battery using a cloth. The
battery may explode as a result of elec-
trostatic charge or due to flying sparks.
! Switch off the engine and remove the
key/KEYLESS GO * button before loosen-
ing or removing the battery terminal
clamps. You may otherwise destroy elec-
tronic components such as the alternator.
i Mercedes-Benz recommends that you
have all work involving the battery, e.g.
removing, charging and replacing, carried
out at a qualified specialist workshop, e.g.
a Mercedes-Benz Service Centre.
The battery is located under the front seat on
the right-hand side when viewed in the direc-
tion of travel. Practical advice

X
Electrical consumers can be switched on
again. Do not switch the lights on, however,
as this will overload the battery.
X Remove the jump lead from earth

specialist workshop, e.g. a Mercedes-Benz
Service Centre. Towing and tow-starting
Points to remember
G
Risk of accident
If you tow the vehicle, you must use a rigid
towing bar if:
R the engine is not running
R there is a brake system malfunction
R the voltage supply or the vehicle's elec-
trical system is damaged
The electric power steering and the brake
force booster do not work when the engine
is not running. Greater braking force will
then be required and the brake pedal travel
will be longer. If necessary, depress the
brake pedal with maximum force.
Do not tow the vehicle if the key cannot be
turned in the ignition lock. If this is the case,
the steering is locked and the vehicle can-
not be steered.
If you tow or tow-start another vehicle, its
weight must not exceed the maximum per-
missible gross vehicle weight of your vehi-
cle.
It is better to have the vehicle transported
than to have it towed. When towing, observe the legal requirements
in all countries concerned.
!
When towing, pull away slowly and with-
out jerking. If the tractive power is too high,
the vehicles could be damaged.
! Do not use the towing eye for recovery,
as this will damage the vehicle. If in doubt
recover the vehicle with a crane.
! You may tow the vehicle for a maximum
of 50 km. A towing speed of 50 km/h must
not be exceeded.
With towing distances over 50 km, the
entire vehicle needs to be lifted up and
transported.
! On vehicles with KEYLESS GO*: use the
key instead of the KEYLESS GO * button.
Turn the key to position 2in the ignition
lock and set the automatic transmission to
N. Then turn the key back to 0and leave it
in the ignition lock.
! Only secure the tow cable or towing bar
to the towing eyes. You may otherwise
damage the vehicle. Practical advice

Towing and tow-starting
331
R
Tow-starting the vehicle is not permitted.
R Vehicles with 4MATIC *must not be towed
with the front or rear axle raised.
R If the engine does not start, try jump-start-
ing it (Y page 329).
R If it is not possible to jump-start the vehicle,
have it towed to the nearest qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre.
R If the vehicle has suffered transmission
damage, have it carried away on a trans-
porter or trailer.
R If you are towing the vehicle, move the
automatic transmission selector lever to
N and turn the key to position 2
(Y page 76) in the ignition lock.
R Before towing the vehicle, make sure that
the battery is connected and charged. Oth-
erwise:
- you cannot switch on the ignition
- you cannot move the selector lever to N
- you have no support when braking
i Before towing the vehicle, deactivate tow-
away protection* (Y page 64)and the auto-
matic door locking feature (Y page 134).You could otherwise be locked out when
pushing or towing the vehicle. Fitting the towing eye
Opening the front cover The mountings for the removable towing eyes
are located in the bumpers. They are located
at the front and rear under the covers on the
right-hand side of the vehicle when viewed in
the direction of travel. 1

Towing and tow-starting
332 Towing the vehicle
! You may tow the vehicle for a maximum
of 50 km. A towing speed of 50 km/h must
not be exceeded.
With towing distances over 50 km, the
entire vehicle needs to be lifted up and
transported.
! Vehicles with 4MATIC* must not be
towed with the front or rear axle raised.
! If you have the vehicle towed with the
front or rear axle raised, the ignition must
be switched off (key in position 0or 1in the
ignition lock). Intervention by ESP ®
could
otherwise destroy the braking system on
the front or rear axle.
X Turn the key to position 2(Y page 76) in
the ignition lock.
i On vehicles with KEYLESS GO*: use the
key instead of the KEYLESS GO * button.
X Move the DIRECT SELECT lever to the N
position. Removing the towing eye
X Take the wheel wrench from the vehicle
tool kit ( Ypage 252).
X Insert the wheel wrench handle into the
towing eye and turn it anti-clockwise.
X Unscrew the towing eye.
X Replace the cover and press it until it
engages.
X Return the towing eye and the wheel
wrench to the vehicle tool kit. Transporting the vehicle
The towing eyes or trailer coupling *can be
used to pull the vehicle onto a trailer or trans-
porter if you wish to transport it.
! Only lash the vehicle down by the wheels
or wheel rims, not by parts of the vehicle
such as axle or steering components. The
vehicle could otherwise be damaged. Recovering a vehicle that has become
stuck
Take great care when recovering a vehicle
whose drive wheels have become embedded
in loose earth or mud, particularly if the vehi-
cle is laden.
When recovering the vehicle do not use jerky
movements and do not pull it at an angle. The
chassis could otherwise be damaged.
Never attempt to recover a vehicle with a
trailer attached.
Pull out the vehicle backwards, if possible
using the tracks it made when it became
stuck. Towing in the event of the following
malfunctions
In the event of damage to the transfer
case Have the propeller shafts between the axles
and the transfer case removed.
Have the vehicle towed with the front axle
raised.Practical advice
