gency spare wheel* G
Risk of accident
The wheel dimensions and tyre size of the
emergency spare wheel* may differ from
those of the standard wheels.
The handling characteristics of your vehicle
will change if you fit an emergency spare
wheel*. Adapt your style of driving accord-
ingly.
You may only use the emergency spare
wheel* for a short while. Do not exceed the
maximum speed of 80 km/h and do not deac-
tivate ESP ®
.
Never drive the vehicle with more than one
emergency spare wheel* fitted. G
Risk of accident
Have the emergency spare wheel* replaced
as soon as possible at a qualified specialist
workshop which has the necessary specialist
knowledge and tools to carry out the work
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 systems must be
carried out at a qualified specialist workshop.
Preparing the vehicle X
Prepare the vehicle as described
(Y page 222).
X If a trailer is coupled, uncouple it.
X Place the wheels in the straight-ahead posi-
tion.

Raising the vehicle G
Risk of injury
The jack is designed only to raise and hold the
vehicle for a short time while a wheel is being
changed.
You must use axle stands if you are carrying
out work on the vehicle.
Make sure that the jack is placed on a firm,
non-slip, level surface. Do not use wooden
blocks or similar objects as a jack underlay.
Otherwise, the jack will not be able to achieve
its load-bearing capacity due to the restricted
height.
Do not start the engine at any time while a
wheel is being changed.
Do not lie under the vehicle when it is being
supported by the jack. If you do not raise the
vehicle as described, it could slip off the jack
(e.g. if the engine is started or if a door or the
tailgate is opened or closed) and you could be
seriously injured. 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
Thus, it is important to make sure that the jack
is positioned correctly in the respective jack-
ing points. Before positioning the jack,
remove any dirt that may have collected in the
jacking points. 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. 228 Flat tyrePractical advice

Charging and fitting the battery
G
Risk of injury
Only charge the battery in a well-ventilated
area. As the battery is being charged, gases
can escape and generate minor explosions.
This may injure you and other persons or
cause damage to the paintwork or acid cor-
rosion on the vehicle.
You can obtain information about battery
chargers which allow the battery to be
charged when still installed from a qualified
specialist workshop, e.g. a Mercedes-Benz
Service Centre. G
Risk of injury
There is a risk of acid burns during the charg-
ing process due to the gases which escape
from the battery. Do not lean over the battery
during the charging process. G
Risk of injury
Battery acid is caustic. Avoid contact with the
skin, eyes or clothing.
! Only charge the installed battery with a
battery charger which has been tested and
approved by Mercedes-Benz. These battery
chargers allow the battery to be charged
while it is still installed. However, the bat-
tery must always be disconnected first.
! Only use battery chargers with a maxi-
mum charging voltage of 14.8 V.
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 233) in
reverse order. 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 (e.g.
radio, blower, etc.).
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 on the side of the battery.
X Close the bonnet.
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 102).
R reset the panorama sliding sun-
roof* (Y page 127)
R reset the function for folding the exterior
mirrors in/out automatically* by folding
the mirrors out once (Y page 68). 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 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 have a sufficient
cross-section and insulated terminal
clamps. 234 Jump-startingPractical advice

When towing, observe the legal requirements
in all countries concerned.
!
When towing, pull away slowly and with-

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/hm ust
not be exceeded.

damage the vehicle.
R Tow-starting the vehicle is not permitted.
R The vehicle is equipped with 4MATIC and
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 234).
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 The automatic transmission selector lever
must be in the Nposition when towing the
vehicle away.
R If you are towing the vehicle, move the
automatic transmission selector lever to
N and turn the key to position

N.
- you have no support when braking.
i Switch off the automatic locking feature
before the vehicle is towed. Otherwise, you
could be locked out when pushing or tow-
ing the vehicle.
Deactivate tow-away protection* before
the vehicle is towed ( Ypage 55). 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 162)and connect the towbar

! Only secure the vehicle by the wheels or
wheel rims, not by parts of the vehicle such
as axle or steering components. Otherwise,
the vehicle could be damaged.
X Turn the key to position 2(Y page 61) in
the ignition lock.

Notes on changing fuses
The fuses in your vehicle serve to close down
faulty circuits. If a fuse blows, all the compo-
nents on the circuit and their functions will
fail.
Blown fuses must be replaced with fuses of
the same rating, which you can recognise by
the colour and value. The fuse ratings are lis-
ted in the fuse allocation chart. A Mercedes-
Benz Service Centre will be happy to advise
you. G
Risk of fire
Only use fuses that have been approved for
Mercedes-Benz vehicles and which have the 238 FusesPractical advice
