wise pattern in the sequence indica-
ted ( 1 to 5). The tightening torque must
be 130 Nm. G
Risk of accident
Have the tightening torque checked imme-
diately after a wheel is changed. The wheels
could work loose if they are not tightened
to a tightening torque of 130 Nm.
X Turn the jack back to its initial position and
store it and the rest of the vehicle tool kit
in the boot.

Jump-starting
291
X
Charge the battery. Observe the notes in
the operating instructions for your battery
charger.
X Refit the charged battery.
To do this, follow the steps described in
"Removing the battery"
(Y page 290) in
reverse order.
! Do
not fit refillable batteries without elec-
trostatic protection. The electrostatic dis-
charge could otherwise cause the battery
to explode. The battery acid released could
cause damage to your vehicle.
Further information on electrostatic protec-
tion (Y page 289). G
Risk of injury
Battery acid is caustic. Avoid contact with
the skin, eyes or clothing. Reconnecting the battery
! Always reconnect the battery in the
sequence

described below. Never swap the
terminal clamps. You may otherwise dam-
age the vehicle electronics.
X Switch off all electrical consumers.
X Connect the positive terminal clamp and
secure the cover.
X Connect the negative terminal clamp.
X Connect the breather hose. Make sure that
a

cell cap is fitted between the battery and
the breather hose.
X Refit the electrostatic protection if neces-
sary ( Y page 289).
i If
the battery power supply has been inter-
rupted (e.g. if it has been reconnected), you
must carry out the following tasks:
R Set the time (Y page 125).
R Reset the sliding/tilting sunroof*
(Y page 171).
R Reset the function for folding the exterior
mirrors in/out automatically* by folding
the mirrors out once ( Y page 84). Jump-starting
If your vehicle's battery is discharged, the
engine can be jump-started from another
vehicle

or from an external battery using jump
leads.
Observe the following points:
R Jump-starting must only be performed
when the engine and catalytic converter
are cold.
R Do not start the engine if the battery has
frozen. Thaw the battery out first.
R Jump-starting may only be performed from
12V batteries.
R Only use jump leads which are protected
against polarity reversal and which have a
sufficient cross-section and insulated ter-
minal clamps.
i Jump leads which are protected against
polarity reversal and further information
about jump-starting can be obtained from
any Mercedes-Benz Service Centre.
! Avoid repeated and lengthy starting
attempts.
Never start the vehicle using a rapid battery
charger. Practical advice
* optional

Towing and tow-starting
293Towing 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
There
is no power assistance for the steer-
ing when the engine is not running. G
Risk of accident
The vehicle is braked when HOLD is activa-
ted.
Therefore, deactivate HOLD if the vehi-
cle is to be towed.
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.
! 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.
! Only secure the tow cable or towing bar
to the towing eyes. You may otherwise
damage the vehicle.
R Vehicles with an automatic transmission
must not be tow-started.
R If the engine does not start, try jump-start-
ing it (Y page 291).
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, only tow it with the propeller shaft
disconnected.
R The selector lever must be in position N on
vehicles with automatic transmission. R
If you are towing the vehicle over a consid-
erable distance, this may only be done with
the rear 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
- You have no support when braking
i Switch off the automatic locking feature
before the vehicle is towed (Y page 127).
You could otherwise be locked out when
pushing or towing the vehicle. Practical advice

X Insert the wheel wrench handle into the
towing eye and tighten. 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.
! The engine must be switched off (key in
ignition lock in position 0 or position 1) if
the vehicle is being towed with the rear axle
raised or if the parking brake is being tested
on a dynamometer. Intervention by ESP ®
could otherwise damage the brake system.
X Turn the key to position 2 in the ignition
