X Open the battery cover ( Ypage 264).
X Connect positive terminal 2on your vehi-
cle to positive terminal 1of the donor bat-
tery using the jump lead, beginning with
your own battery.
X Start the engine of the donor vehicle and
run it at idling speed.
X Connect negative terminal 3of the donor
battery to negative terminal 4of your
vehicle's battery using the jump lead, con-
necting the jump lead to the donor battery
first.
X Start the engine. X
Electrical consumers can be switched on
again. Do not, however, switch on the lights
as this places too heavy a load on the bat-
tery.
X Remove the jump lead from earth
point 4and negative terminal 3first,
then from positive terminals 1and 2,
each time disconnecting from the battery
on your own vehicle first.
X Have the battery checked at a qualified
specialist workshop, e.g. a Mercedes-Benz
Service Centre. Towing and tow-starting
Points to remember
G
Risk of accident
If you have the vehicle towed, you must use
a rigid towing bar if:
R the engine is not running.
R there is a brake system malfunction.
R there is a malfunction in the voltage sup-
ply or the vehicle's electrical system.
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 brake pedal travel will
be longer. If necessary, depress the brake
pedal with full 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. Practical advice

Towing and tow-starting
268
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 could 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.
For towing distances over 50 km, the entire
vehicle needs to be lifted up and transpor-
ted.
! Only secure the tow cable or towing bar
to the towing eyes. You may otherwise
damage the vehicle.
R Vehicles with AUTOTRONIC* must not be
tow-started.
R If the engine does not start, try jump-start-
ing it (Y page 266).
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
The selector lever must be in position N
when towing a vehicle with AUTO-
TRONIC*.
R If you are towing the vehicle over a consid-
erable distance, this must only be done
with the front axle raised.
R The ignition must be switched off if you are
towing the vehicle with the front/rear axle
raised. Intervention by ESP ®
could other-
wise damage the brake system.
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(on vehicles with AUTOTRONIC*)
- you have no support when braking
i Switch off the automatic locking feature
before the vehicle is towed (Y page 110).
You could otherwise be locked out when
pushing or towing the vehicle. Fitting the towing eye
Vehicles with a trailer tow hitch: if you
intend to use the vehicle for towing, fit the ball
coupling (Y page 186) and connect the tow-
bar to this.
Opening the front cover The mountings for the removable towing eyes
are in the bumpers. They are located at the
front and rear behind covers on the right-hand
side of the vehicle when viewed in the direc-
tion of travel.
