WARNING
During the charging process, a battery produ-
ces hydrogen gas. If a short circuit occurs or
sparks are created, the hydrogen gas can
ignite. There is a risk of an explosion.
R Make sure that the positive terminal of a
connected battery does not come into con-
tact with vehicle parts.
R Never place metal objects or tools on a bat-
tery.
R It is important that you observe the descri-
bed order of the battery terminals when
connecting and disconnecting a battery.
R When jump-starting, make sure that the
battery poles with identical polarity are
connected.
R It is particularly important to observe the
described order when connecting and dis-
connecting the jumper cables.
R Never connect or disconnect the battery
terminals while the engine is running.
Disconnecting the starter battery !
Switch off the engine and remove the key
from the ignition lock before you loosen or
disconnect the terminal clamps. You may
otherwise destroy electronic components

R
Only use jumper cables that have a suffi-
cient cross-section and insulated terminal
clamps.
R If the battery is fully discharged, attach the
battery of another vehicle for a few minutes
before attempting to start. This charges the
empty battery a little.
R Make sure that the two vehicles do not
touch.
Make sure that:
R the jumper cables are not damaged.
R bare parts of the terminal clamps do not
come into contact with other metal parts
while the jumper cables are connected to
the battery.
R the jumper cables cannot come into con-
tact with parts such as the V-belt pulley or
the fan. These parts move when the engine
is started and while it is running.
i Jumper cables and further information
regarding jump starting can be obtained at
any qualified specialist workshop. Before connecting the jumper cables
On vehicles with a battery main switch, check
whether the battery main switch is switched
on (Y page 136).
X Apply the parking brake.
X Move the selector lever of the automatic
transmission to position P.
X Switch off all electrical consumers, e.g.
audio equipment, blower.
X Turn the key to position 0in the ignition
lock and remove it (Y page 137).
X Open the hood (Y page 250). Tow-starting and towing away
Important safety notes
G
WARNING
Functions relevant to safety are restricted or
no longer available if:
R the engine is not running.
R the brake system or the power steering is
malfunctioning.
R there is a malfunction in the voltage supply
or the vehicle's electrical system.
If your vehicle is being towed, much more
force may be necessary to steer or brake.
There is a risk of an accident.
In such cases, use a tow bar. Before towing,
make sure that the steering moves freely. G
WARNING
You can no longer steer the vehicle if the
steering wheel lock has been engaged. There
is a risk of an accident.
Always switch off the ignition when towing the
vehicle with a tow cable or a tow bar. G
WARNING
If the weight of the vehicle to be towed or tow-
started is greater than the permissible gross
weight of your vehicle:
R the towing eye could detach itself
R the vehicle/trailer combination could roll-
over.
There is a risk of an accident.
When towing or tow-starting another vehicle,
its weight should not be greater than the per-
missible gross weight of your vehicle.
Information on your vehicle's gross vehicle
weight rating can be found on the vehicle
identification plate (Y page 319).
! Only secure the tow rope or tow bar at the
towing eyes. Otherwise, the vehicle could
be damaged. Tow-starting and towing away

!
Observe the following points when towing
with a tow rope:
R Secure the tow rope on the same side on
both vehicles.
R Ensure that the tow cable is not longer
than legally permitted. Mark the tow
cable in the middle, e.g. with a white
cloth (30 x 30 cm). This will make other
road users aware that the vehicle is being
towed.
R Only secure the tow cable to the towing
eye.
R Observe the brake lamps of the towing
vehicle while driving. Always maintain a
distance so that the tow rope does not
sag.
R Do not use steel cables or chains to tow
your vehicle. You could otherwise dam-
age the vehicle.
! Do not use the towing eye for recovery,
this could damage the vehicle. If in doubt,
recover the vehicle with a crane.
! When towing, pull away slowly and
smoothly. If the tractive power is too high,
the vehicles could be damaged.
Observe the legal requirements for the rele-
vant country when towing.
It is preferable to have the vehicle trans-
ported on a transporter or trailer instead of
towing it.
The automatic transmission selector lever
must be in the Nposition when towing the
vehicle.
The battery must be connected and charged.
Otherwise, you:
R cannot turn the key in the ignition lock to
position 2
R cannot move the selector lever to position
N on vehicles with automatic transmission.
i Switch off the automatic locking feature
before the vehicle is towed (Y page 71). You
could otherwise lock yourself out of the
vehicle when pushing or towing away the
vehicle. Installing/removing the towing eye
The fixture for the front towing eye is located in the
bumper.
Rear towing eye under the bumper, attached to the
chassis
Your vehicle may be equipped with rear tow-
ing eye 0044. If you tow or tow-start a vehicle,
attach the towing device to rear towing
eye 0044.
If your vehicle is equipped with a trailer tow
hitch, attach the towing device to the trailer
tow hitch (Y page 173).
Installing the front towing eye
X Take the towing eye and screwdriver from
the vehicle tool kit (Y page 276).
X Press cover 0043and remove cover 0043from
the opening.
You will see the fixture for the towing eye.
X Screw in the towing eye clockwise to the
stop.
X Insert screwdriver into the towing eye and
tighten it. 280

Removing the front towing eye
X
Remove the screwdriver from the vehicle
tool kit.
X Insert the screwdriver into the towing eye
and turn the screwdriver counter-clock-
wise.
X Unscrew the towing eye.
X Insert cover 0043with the lug at the bottom
and press it in at the top until it engages.
X Place the towing eye and screwdriver back

With transmission damage !
Always use new bolts when installing the
propeller shafts.
i Only have the propeller shafts fitted/
removed at a qualified specialist workshop.
If the vehicle has transmission damage, have
the propeller shaft removed before towing
away.
In the event of damage to the electrical
system If the battery is defective, the automatic
transmission will be locked in position P. In
order to be able to shift the automatic trans-
mission to position N, you must provide
power to the vehicle's 12 V electrical system
in the same way as when jump-starting
(Y page 278).
Have the vehicle transported on a transporter
or trailer. Towing with the front or rear axle
raised
General notes !
The ignition must be switched off if the
vehicle is being towed with the front or rear axle raised. Otherwise, ESP
®
may intervene
and damage the brake system.
! Always use new bolts when installing the
propeller shafts.
i Only have the propeller shafts fitted/
removed at a qualified specialist workshop.
Observe the following before towing a vehicle
with a raised front or rear axle:
R the information on towing in the event of
malfunctions (Y page 281) and
R the important safety notes (Y page 279).
If the front axle is damaged, raise the vehicle
at the front axle and if the rear axle is dam-
aged, raise the vehicle at the rear axle.
Towing If the front axle is raised, the vehicle may be
towed a maximum of 30 miles
(50 km). For a
towing distance of over 30 miles (50 km), you
must remove the propeller shafts to the
driven axles.
