Make sure that there is sufficient clearance
around the pedals when floormats are
used, and that the floormats are properly
secured.
The floormats must be secured at all times
using retainers and studs.
Before you drive off, make sure that the
floormats are secure and rectify if neces-
sary. A floormat which is not properly secured can slip and thereby interfere with
the movement of the pedals.
Do not place floormats on top of one

Active Service System PLUS
ASSYST PLUS, the Active Service System,
tells you when the next service is due. When-
ever a service is due, this is shown in the
multi-function display:
Service A due in .. days
Service A due in .. km
Service A due now The letter indicates how much time the work-
shop will require to carry out the service work.
The letters displayed range from
Afor a short
service duration to Hfor a long service dura-
tion.
ASSYST PLUS does not record any periods of
time during which the battery is disconnec-
ted. In order to maintain the time-dependent
service schedule, you should call up the
service due date and make a note of it before
you disconnect the battery. The alternative is to subtract the battery-disconnection periods
from the service date shown on the display. Fading out the service message

324 required. Mercedes-Benz recommends
that you use a Mercedes-Benz Service
Centre for this purpose. In particular, work
relevant to safety or on safety-related sys-
tems must be carried out at a qualified
specialist workshop.
Preparing the vehicle X
Prepare the vehicle as described
(Y page 317).
X If a trailer is coupled, uncouple it.
X Place the wheels in the straight-ahead posi-
tion.

area beneath the boot/luggage compart-
ment floor:
R the "Minispare"/collapsible emergency
spare wheel* or the spare wheel*
R the vehicle tool kit
R the wheel chock
R the jack
X Secure the vehicle to prevent it from rolling
away.
On level ground: place chocks or similar
under the front and rear of the wheel that is diagonally opposite the wheel you wish
to change.
X On downhill gradients: place chocks or
similar under both wheels of the other axle.
Raising the vehicle 1
Wheel wrench
X Using wheel wrench 1, loosen the bolts on
the wheel you wish to change by about one
full turn. Do not unscrew the bolts com-
pletely. G
Risk of accident
If you fail to position the jack correctly, the
vehicle may: R
slip off the jack
R injure you or others
R be damaged
It is thus important to ensure that the jack
is positioned correctly in the respective
jacking points. Before positioning the jack,
remove any dirt that may have collected in
the jacking points.
The jacking points for the jack are located
behind the wheel housings of the front wheels
and in front of the wheel housings of the rear
wheels. 1

Jump-starting
333
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 332) 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 331). 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 331).
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 135).
R Reset the sliding/tilting sunroof*
(Y page 182).
R Reset the function for folding the exterior
mirrors in/out automatically* by folding
the mirrors out once (Y page 91). Jump-starting
Jump-starting your vehicle
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 may only be performed when
the engine and catalytic converter are cold.
R Do not start the engine if the battery is fro-
zen. Let the battery thaw first.
R Jump-starting may only be performed from
batteries with a nominal voltage of 12 V.
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

Towing and tow-starting
337Towing 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 boosting effect 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. 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 (Y page 333).
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 automatic transmission* selector lever
must be in the Nposition when towing the
vehicle away.
R If you are towing the vehicle over a consid-
erable distance, this must 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 Vehicles with 4MATIC* may not be towed
with the front or rear axle raised.
R Before towing the vehicle, make sure that
the battery is connected and charged. Oth-
