Warning messages of the tyre pressure
monitor If the tyre pressure monitor detects a pres-
sure loss in one or more tyres, a warning mes-
sage is shown in the multifunction display and the yellow tyre pressure monitor warning
lamp comes on.
R If the Please correct tyre pressure
Please correct tyre pressure
message appears in the multifunction dis-
play, the tyre pressure in at least one tyre is too low and must be corrected at the next
opportunity.
R If the Check tyre(s)
Check tyre(s) message appears in
the multifunction display, the tyre pressure
in one or more tyres has dropped signifi-
cantly and the tyres must be checked.
R If the Warning tyre defect
Warning tyre defect message
appears in the multifunction display, the
tyre pressure in one or more tyres has drop-
ped suddenly and the tyres must be
checked.
Observe the instructions and safety notes in
the display messages in the "Tyres" section
(Y page 295).
If the wheel positions on the vehicle are inter-
changed, the tyre pressures may be displayed for the wrong positions for a short time. After
a few minutes of driving, this is rectified and
the tyre pressures are displayed for the cor-
rect positions.
Restarting the tyre pressure monitor When you restart the tyre pressure monitor,
all existing warning messages are deleted and
the warning lamps go out. The monitor uses
the currently set tyre pressures as the refer-
ence values for monitoring. In most cases, the tyre pressure monitor will automatically
detect the new reference values after you
have changed the tyre pressure. However,
you can also define reference values man-
ually as described here. The tyre pressure
monitor then monitors the new tyre pressure values. X
Use the table on the inside of the fuel filler
flap to ensure that the tyre pressure is set
correctly in all four tyres for the current
operating conditions.
Also observe the notes in the section on
tyre pressures (Y page 380).

for the respective operating conditions.
The recommended tyre pressures can be
found in the table on the fuel filler flap.
The tyre pressure loss warning system can only give reliable warnings if you have set
the correct tyre pressure. If an incorrect
tyre pressure is set, these incorrect values
will be monitored.

Interchanging the wheels
G
WARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
the wheels or tyres have different dimensions. The wheel brakes or suspension components may also be damaged. There is a risk of acci-
dent.
Interchange front and rear wheels only if the
wheels and tyres are of the same dimensions.
! On vehicles fitted with a tyre pressure
monitor, electronic components are loca-
ted in the wheel.
Tyre-fitting tools should not be applied in
the area of the valve, as this could damage
the electronic components.
Only have tyres changed at a qualified spe- cialist workshop.
Interchanging the front and rear wheels of
differing dimensions can render the general
operating permit invalid.
Observe the instructions and safety notes in
the "Fitting a wheel" section (Y page 386).
The wear patterns on the front and rear tyres differ depending on the operating conditions.Interchange the wheels before a clear wear
pattern has formed on the tyres. Front tyres
typically wear more on the shoulders and the
rear tyres in the centre.
On vehicles that have the same size front and
rear wheels, you can interchange the wheels
every 5,000 to 10,000 km depending on the
degree of tyre wear. Ensure the direction of
rotation is maintained.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time a wheel is interchanged. Check the tyre pressure and,
if necessary, restart the tyre pressure loss
warning system (Y page 385) or the tyre pres-
sure monitor (Y page 383) . Direction of rotation
Tyres with a specified direction of rotation
have additional benefits, e.g. if there is a risk of aquaplaning. These advantages can only begained if the tyres are fitted corresponding to
the direction of rotation.
An arrow on the sidewall of the tyre indicates
its correct direction of rotation. Storing wheels
Store wheels in a cool, dry and preferably
dark place if they are not being used. Protect the tyres against oil, grease, petrol and diesel. Fitting a wheel
Preparing the vehicle X
Stop the vehicle on solid, non-slippery and
level ground.
X Apply the electric parking brake manually.
X Move the front wheels to the straight-
ahead position.
X Shift the transmission to position P.
X Make sure that "normal" level is selected
for AIRMATIC (Y page 210).
X Switch off the engine.
X Open the driver's door.
The on-board electronics now have status
0. This is the same as the key having been
removed.
X Remove the Start/Stop button from the
ignition lock (Y page 161).
or, if the key is inserted in the ignition lock: X Remove the key from the ignition lock.
X If included in the vehicle equipment,
remove the tyre-change tool kit from the
vehicle.
X Safeguard the vehicle against rolling away.

used incorrectly, it could tip over while the
vehicle is raised.
R the jack is designed only to raise and hold
the vehicle for a short time while a wheel
is being changed. It is not suitable for per-
forming maintenance work under the vehi-
cle.
R avoid changing the wheel on uphill and
downhill slopes.
R before raising the vehicle, safeguard it from
rolling away by applying the parking brake
and positioning wheel chocks. Do not
release the parking brake while the vehicle is raised.
R the jack must be placed on a firm, flat and
non-slip surface. On a loose surface, a
large, flat load-bearing underlay must be
used. On a slippery surface, a non-slip
underlay must be used, e.g. rubber mats.
R 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.
R make sure that the distance between the
underside of the tyres and the ground does not exceed 3 cm.
R never place your hands or feet under the
raised vehicle.
R do not lie under the vehicle.
R do not start the engine when the vehicle is
raised.
R do not open or close a door or the boot lid
when the vehicle is raised.
R make sure that no persons are present in
the vehicle when the vehicle is raised.
Vehicles with AMG wheels and hub caps:
the hub cap covers the wheel bolts. Before
you can unscrew the wheel bolts, you must
remove the hub cap. Two different variants
can be fitted. Vehicles with AMG wheels and plastic
hub caps:
X To remove: turn the centre cover of hub
cap :anti-clockwise and remove.
X To fit: before fitting, ensure that hub cap :
is in the open position. To do this, turn the
centre cover anti-clockwise.
X Position hub cap :and turn the centre
cover clockwise until hub cap :engages
physically and audibly.
X Make sure that hub cap :is fitted
securely. Vehicles with AMG wheels and aluminium
hub caps:
X To remove: take socket;and wheel
wrench =from the vehicle tool kit
(Y page 357).
X Position socket ;on hub cap :.

Do not use distilled or de-ionised water in
the washer fluid reservoir. Otherwise, the
level sensor may be damaged.
! Only the washer fluids SummerFit and
WinterFit can be mixed. Otherwise, the
spraying nozzles could become blocked.
At temperatures above freezing:
X Fill the washer fluid reservoir with a mixture
of water and washer fluid, e.g. MB Sum-

Mix 1 part MB SummerFit to 100 parts water.
At temperatures below freezing:
X Fill the washer fluid reservoir with a mixture
of water and washer fluid, e.g. MB Winter-

The correct mixing ratio can be taken from
the information on the antifreeze protec-
