Risk of accident
The windscreen will not longer be properly
wiped if the wiper blades are worn. This
could prevent you from observing the traffic
conditions, thereby causing an accident.
Replace the wiper blades twice a year, ide-
ally in spring and autumn. G
Risk of accident
The wiper arms could start moving and
cause an injury if you leave the windscreen
wipers switched on.
Remove the key from the ignition lock
before replacing the wiper blades.

Flat tyre
318 Make sure that the jack is placed on a firm,
non-slip, level surface. Do not use wooden
blocks or similar as jacking supports. Oth-
erwise, the jack will not be able to achieve
its load-bearing capacity due to the restric-
ted height.
Do not start the engine at any time while
the 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 a door
or the boot lid/tailgate is opened or closed)
and you could sustain serious injuries. Using the TIREFIT kit
You can use the TIREFIT kit to seal small
punctures, particularly those in the tyre tread.
You can use TIREFIT in outdoor temperatures
down to -20 °C. G
Risk of accident
In the following situations, your safety is at
particular risk and TIREFIT is unable to pro-
vide breakdown assistance: R
if there are cuts or punctures in the tyre
greater than 4 mm
R if the wheel rim is damaged
R if you have driven at very low tyre pres-
sures or on a flat tyre
Do not drive any further. Consult a qualified
specialist workshop which has the neces-
sary 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 work-
shop.
X Do not remove any foreign objects which
have penetrated the tyre, e.g. screws or
nails.
X Remove TIREFIT, the accompanying "max.
80 km/h "sticker and the electric air pump
from the stowage well underneath the
boot/luggage compartment floor
(Y page 254). 1

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.
X Take out the following from the stowage
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

Open the pressure release screw on the
pressure gauge until the tyre pressure is
correct.
X Disconnect the electric air pump and stow
it away.

is standing firmly on the ground again.
X Place the jack to one side. 1
–5 Wheel bolts
X Tighten the wheel bolts evenly in a cross-
wise pattern in the sequence indica-
ted ( 1to5). 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 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/luggage compartment.
Vehicles with the "Minispare"/collapsible
emergency spare wheel*:
X Pack the faulty wheel in the protective film
provided with the "Minispare"/collapsible
emergency spare wheel* and transport the
wheel in the boot/luggage compartment.
or
X Depending on the size of the wheel, you
may also be able to secure the faulty wheel
in the spare wheel well. In this case, you
will have to remove the stowage well casing
from the spare wheel well and stow it
securely in the boot/luggage compart-
ment.

Battery
330 step out of the vehicle first and touch the
bodywork.
R Do not wipe the battery using a cloth. The
battery may explode as a result of elec-
trostatic charge or due to flying sparks.
! Switch the engine off and remove the key
before unscrewing or disconnecting the
terminal clamps from the battery. You may
otherwise destroy electronic components
such as the alternator.
i Mercedes-Benz recommends that you
have all work involving the battery, e.g.
removing, charging and replacing, carried
out at a qualified specialist workshop, e.g.
a Mercedes-Benz Service Centre.

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
charging process due to the gases which
escape from the battery. Do not lean over
the battery during the charging process.
! 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. Otherwise, the vehi-
cle's electronic system may be damaged.
! Only use battery chargers with a maxi-
mum charging voltage of 14.8 V. Practical advice
