To obtain an accurate display of your com-
pass bearing, the correct geographical zone
must be set. If necessary, the compass must
also be calibrated (Y page 167).
If the compass is not calibrated or is malfunc-
tioning due to external interference, you will
see the Compass – – – message in the dis-
play.
i Large buildings, bridges, power lines or
large transmitting masts as well as metallic objects in or on the vehicle may interfere
with the compass display.

Risk of accident
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 correctly secured at all
times using retainers and press-studs. Before you drive off, check the floormats and
secure if necessary. A floormat which is not
properly secured can slip and, thereby, inter-
fere with the movement of the pedals.
Do not place floormats on top of one another.

The infrared reflecting glass prevents the
vehicle interior from becoming too hot. It also
blocks radio waves up into the gigahertz
range. In order to operate radio-controlled equip-
ment (e.g. toll recording systems), areas :
on the windscreen are transparent to radio
waves. You can install radio-controlled sys-
tems here. These areas can best be seen from 168

Tyres and wheels
Points to remember
! For safety reasons, Mercedes-Benz rec-
ommends that you only use tyres, wheels
and accessories which have been approved
by Mercedes-Benz specifically for your
vehicle. These tyres have been specially
adapted for use with the control systems,
such as ABS or ESP ®
, and are marked as
follows:
R MO = Mercedes-Benz Original
R MOE = Mercedes-Benz Original Exten-
ded* (tyres with run-flat characteristics)
Only use Mercedes-Benz Original Extended
tyres* on wheels that have been specifi-
cally approved by Mercedes-Benz.
If you use other tyres, wheels and acces-
sories, Mercedes-Benz cannot accept any
responsibility for damage that may result
from this. Further information about tyres,
wheels and approved combinations can be
obtained from any Mercedes-Benz Service
Centre.
! If you fit tyres other than those tested and
recommended by Mercedes-Benz, charac-
teristics such as handling, noise levels and
fuel consumption, etc. may be adversely
affected. In addition, when driving with a
load, tyre dimensional variations could
cause the tyres to come into contact with
the bodywork and axle components. This
could result in damage to the tyres or the
vehicle.
! Retreaded tyres are neither tested nor
recommended by Mercedes-Benz, since
previous damage cannot always be detec-
ted on retreaded tyres. As a result,
Mercedes-Benz cannot guarantee vehicle
safety if retreaded tyres are fitted. Do not
fit used tyres if you have no information
about their previous usage. G
Risk of accident
Tyres, wheels or accessories which have not
been approved by Mercedes-Benz for your
vehicle or are not used as they should be, can
impair driving safety. As a result, you could
cause an accident. Before purchasing and
using them, enquire about their suitability,
legal stipulations and factory recommenda-
tions at a Mercedes-Benz Service Centre.
Modification work on the brake system and
wheels is not permitted, nor is the use of
spacer plates or brake dust shields. This inva-
lidates the General Operating Permit for the
vehicle.
Notes on selecting, fitting and replac-
ing tyres R
Only fit tyres and wheels of the same type
and make.
R Only fit tyres of the correct size onto the
wheels.
R After fitting new tyres, run them in at mod-
erate speeds for the first 100 km as they
only reach their full performance after this
distance.
R Fit new tyres on the front wheels first if
tyres of the same size are required on the
front and rear wheels.
R Replace the tyres after six years at the lat-
est, regardless of wear. This also applies to
the spare wheel*.
R Do not drive with tyres which have too little
tread depth, as this significantly reduces
the traction on wet roads (aquaplaning).
! Store tyres that are not being used in a
cool, dry and preferably dark place. Protect
the tyres against oil, grease, petrol and die-
sel.
Notes on regularly inspecting wheels
and tyres R
Regularly check the wheels and tyres of
your vehicle for damage (e.g. cuts, punctu- Tyres and

res, tears, bulges on tyres and deformation,
cracks or severe corrosion on wheels), at
least every 14 days, as well as after driving
off-road or on rough roads. Damaged
wheels can cause a loss of tyre pressure.
R Regularly check the tyre tread depth and
the condition of the tread across the whole
width of the tyre (Y page 180). If neces-
sary, turn the front wheels to full lock in
order to inspect the inner side of the tyre
surface.
R All wheels must have a valve cap to protect
the valve against dirt and moisture. Do not
fit anything onto the valve (such as tyre
pressure monitoring systems) other than
the standard valve cap or other valve caps
approved by Mercedes-Benz for your vehi-
cle.
R Regularly check the pressure of all the tyres
including the spare tyre*, particularly prior
to long trips, and correct the pressure as
necessary (Y page 180).
Notes on driving R
While driving, pay attention to vibrations,
noises and unusual handling characteris-
tics, e.g. pulling to one side. This may indi-
cate that the wheels or tyres are damaged.
If you suspect that a tyre is defective,
reduce your speed and stop the vehicle as
soon as possible to check the wheels and
tyres for damage. Hidden tyre damage
could also be causing the unusual handling
characteristics. If you find no signs of dam-
age, have the wheels and tyres examined
at a specialist workshop, for example at a
Mercedes-Benz Service Centre.
R When parking your vehicle, make sure that
the tyres do not get deformed by the kerb
or other obstacles. If it is necessary to drive
over kerbs, speed humps or similar eleva-
tions, try to do so slowly and at an obtuse
angle. Otherwise, the tyres, particularly the
sidewalls, can get damaged. Direction of rotation
Tyres with a specified direction of rotation
have additional benefits, e.g. if there is a risk
of aquaplaning. You will only gain these ben-
efits if the correct direction of rotation is
observed.
An arrow on the sidewall of the tyre indicates
its correct direction of rotation.
i You may fit a spare tyre* against the
direction of rotation. Tyre tread
G
Risk of accident
Bear in mind that:
R tyre grip decreases rapidly on wet roads
when the tread depth is less than 3 mm.
Thus, you should replace tyres that have
insufficient tread.
R winter tyres should be replaced when the
tread depth is 4 mm or less as they will no
longer provide adequate grip.
R the tread on a tyre may not wear evenly.
Thus, you should regularly check the tread
depth and the condition of the tread across
the entire width of all tyres. If necessary,
turn the front wheels to full lock in order to
inspect the tyre tread more easily.
Otherwise, you could lose control of the vehi-
cle and cause an accident due to the reduced
grip of the tyres on the road. Tyre pressures
i You will find a table of tyre pressures for
various operating conditions on the inside
of your vehicle's fuel filler flap.
The applicable value for the spare
wheel*/"Minispare" emergency spare
wheel* is stated on the spare wheel and in
the technical data section.
Unless otherwise specified, the tyre pres-
sures on the inside of the fuel filler flap are 180

valid for all factory-supplied tyres approved
for the vehicle.
If a tyre size precedes a tyre pressure, the tyre
pressure information following is only valid
for that tyre size.
Instead of the complete tyre size, the rim
diameter alone, for example
R 16or16" may
be listed. Rim diameter
:is part of the tyre size and
can be found on the tyre sidewall. G
Risk of accident
Tyre pressure that is either too high or too low
has a negative effect on the vehicle’s driving
safety, which could lead you to cause an acci-
dent. Therefore, you should regularly check
the pressure of all the tyres, particularly prior
to long trips, and correct the pressure as nec-
essary.
To test tyre pressure, use a suitable pressure
gauge. The outer appearance of a tyre does
not permit any reliable conclusion about the
tyre pressure. On vehicles fitted with the elec-
tronic tyre pressure monitor*, the tyre pres-
sure can be checked in the on-board com-
puter. G
Risk of accident
Do not fit anything else to the tyre valve other
than the standard valve cap. In particular, ret-
rofitted tyre pressure monitors which are
screwed onto the valve may overload it and
cause it to fail. Due to their design, the valve
is kept open continuously, which may lead to
air loss. G
Risk of accident
Should the tyre pressure drop repeatedly:
R check the tyre for foreign bodies.
R check whether the wheel is losing air or the
valve is leaking.
R make sure that only a valve cap approved
by Mercedes-Benz has been fitted on the
tyre valve.
Tyre pressures that are too low have a nega-
tive effect on vehicle safety, which could lead
you to cause an accident.
If possible, you should only correct tyre pres-
sures when the tyres are cold. Depending on
the ambient temperature, the speed you are
driving at and the load on the tyres, the tyre
temperature and thus the tyre pressure may
change by approximately 0.1 bar per 10 †.
Take this into account when checking the
pressure of warm tyres and only correct it if Tyres and wheels
