Check wheels and tyres for damage at least
once a month. Check wheels and tyres after
driving off-road or on rough roads. Damaged
wheels can cause a loss of tyre pressure.
Pay particular attention to damage such as:
R cuts in the tyres
R punctures
R tears in the tyres
R bulges on the tyres
R deformation or severe corrosion on the
wheels
Regularly check the tyre tread depth and the
condition of the tread across the whole width of
the tyre on all tyres (Y page 357). If necessary,
turn the front wheels to full lock to make it easier to inspect the inner side of the tyre surface.
All wheels must have a valve cap to protect the
valve against dirt and moisture. Do not fit any-
thing onto the valve other than the standard
valve cap or other valve caps specially approved for your vehicle by Mercedes-Benz. Do not fit
any other valve caps or systems, e.g. tyre pres-
sure monitors.
Check the pressure of all tyres regularly as well as prior to long trips. Adjust the tyre pressure as
necessary (Y page 359).
Observe the notes on the emergency spare
wheel (Y page 369).
The service life of a tyre depends on various fac-
tors, including the following:
R Driving style
R Tyre pressure
R Mileage Notes on the tyre tread
G
WARNING
Insufficient tyre tread will reduce tyre trac-
tion. The tyre is no longer able to dissipate
water. This means that on wet road surfaces, the risk of aquaplaning increases, in particularwhere speed is not adapted to suit the driving
conditions. There is a risk of accident.
If the tyre pressure is too high or too low, tyres may exhibit different levels of wear at differ-
ent locations on the tyre tread. Thus, you
should regularly check the tread depth and the condition of the tread across the entire
width of all tyres.
Minimum tyre tread depth for:
R summer tyres: 3 mm
R M+S tyres: 4 mm
For safety reasons, replace the tyres before
the legally prescribed limit for the minimum
tyre tread depth is reached. Selecting, fitting and replacing tyres
G
WARNING
Exceeding the stated tyre load-bearing capa-
city and the approved maximum speed could
lead to tyre damage or the tyre bursting. There is a risk of accident.
Therefore, only use tyre types and sizes
approved for your vehicle model. Observe the
tyre load rating and speed rating required for your vehicle.
Pay special attention to country-specific
requirements for tyre approval. These require-
ments may stipulate a specific tyre type for your
vehicle. Furthermore, the use of a specific tyre
type in certain regions and areas of operation
can be highly beneficial. You can find further
information regarding tyres at specialist tyre
retailers, at qualified specialist workshops or at
any Mercedes-Benz Service Centre.
R Use only tyres and wheels of the same type
and make.
Exception: it is permissible to fit a different
type or make in the event of a flat tyre.
Observe the "MOExtended tyres (tyres with
run-flat characteristics)" section
(Y page 341).
R Fit only tyres of the correct size onto the
wheels.
R Run in new tyres at moderate speeds for the
first 100 km. They reach their full perform-
ance only after this distance.
R Do not drive with tyres that have too little
tread depth. This significantly reduces trac-
tion on wet roads (aquaplaning).
R Replace the tyres after six years at the latest,
regardless of wear. Operation

Important safety notes
The tyre pressure warning system does not warn
you of an incorrectly set tyre pressure. Observe
the notes on the recommended tyre pressure
(Y page 359).
The tyre pressure loss warning system does not
replace the need to regularly check the tyre
pressure. An even loss of pressure on several
tyres at the same time cannot be detected by
the tyre pressure loss warning system.
The tyre pressure loss warning system is not
able to warn you of a sudden loss of air, e.g. if the
tyre is penetrated by a foreign object. In the
event of a sudden loss of air, bring the vehicle to
a halt by braking carefully. Avoid abrupt steering manoeuvres.
The function of the tyre pressure loss warning
system is limited or delayed if:
R snow chains are fitted on your vehicle
R road conditions are wintry
R you are driving on a loose surface (e.g. sand or
gravel)
R you adopt a very sporty driving style (corner-
ing at high speeds or driving with high rates of
acceleration)
R you are towing a very heavy or large trailer
R you are driving with a heavy load (in the vehi-
cle or on the roof)
Restarting the tyre pressure loss warn-
ing system Restart the tyre pressure loss warning system if
you have:
R changed the tyre pressure
R changed the wheels or tyres
R fitted new wheels or tyres
X Before restarting, make sure that the tyre
pressures are set properly on all four tyres for
the respective operating conditions. The rec-
ommended tyre pressures can be found in the
tyre pressure 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, this incorrect value will be
monitored.

General notes If a tyre pressure monitor system is fitted, the
vehicle's wheels have sensors fitted that moni-
tor the tyre pressures in all four tyres. The tyre
pressure monitor warns you if the pressure
drops in one or more of the tyres. The tyre pres- sure monitor functions only if the corresponding
sensors are fitted to all wheels.
Information on tyre pressures is shown on the
multifunction display. After a few minutes of
driving, the current tyre pressure of each tyre is
shown in the Service Servicemenu of the multifunction
display; see illustration (example). Tyre pressure

For further information on displaying this mes-
sage, refer to the "Checking the tyre pressure
electronically" section (Y page 362).
Important safety notes It is the driver's responsibility to set the tyre
pressure to the recommended cold tyre pres-
sure suitable for the operating situation
(Y page 359). Note that the correct tyre pres-
sure for the current operating situation must
first be taught-in to the tyre pressure monitor. If
a substantial loss of pressure occurs, the warn- ing threshold for the warning message is aligned
to the taught-in reference values. Restart the
tyre pressure monitor after adjusting to the cold tyre pressure (Y page 363). The current pres-
sures are saved as new reference values. This
ensures that a warning message appears only if
the tyre pressure drops significantly.
The tyre pressure monitor does not warn you of
an incorrectly set tyre pressure. Observe the
notes on the recommended tyre pressure
(Y page 359).
The tyre pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the tyre
is penetrated by a foreign object. In the event of
a sudden loss of air, bring the vehicle to a halt by braking carefully. Avoid abrupt steering
manoeuvres.
The tyre pressure monitor has a yellow warning
lamp on the instrument cluster for indicating a
pressure loss or malfunction. Depending on how
the warning lamp flashes or lights up, a tyre
pressure that is too low or a malfunction in the
tyre pressure monitor is indicated:
R If the warning lamp is lit continuously, the tyre
pressure on one or more tyres is significantly too low. The tyre pressure monitor is not mal-
functioning.
R If the warning lamp flashes for around a
minute and then remains lit constantly, the
tyre pressure monitor is malfunctioning.
In addition to the warning lamp, a message
appears on the multifunction display. Observe
the information on display messages
(Y page 273).
It may take up to ten minutes for a malfunction
of the tyre pressure monitor to be indicated. A
malfunction will be indicated by the tyre pres-
sure warning lamp flashing for approximately
one minute and then remaining lit. When the
fault has been rectified, the tyre pressure warn- ing lamp goes out after you have driven for a few
minutes.
The tyre pressure values indicated by the on-
board computer may differ from those meas-
ured at a filling station using a pressure gauge.
The tyre pressures shown by the on-board com- puter refer to those measured at sea level. At
high altitudes, the tyre pressure values indica-
ted by a pressure gauge are higher than those
shown by the on-board computer. In this case,
do not reduce the tyre pressures.
The operation of the tyre pressure monitor can
be affected by interference from radio transmit- ting equipment (e.g. cordless headphones, two-
way radios) that may be being operated in or
near the vehicle.

After an emergency spare wheel has been fitted,
the system may still display the tyre pressure of
the removed wheel for a few minutes. If this
occurs, note that the value displayed for the
position where the spare wheel is fitted is not
the same as the current tyre pressure of the
emergency spare wheel.
Warning messages of the tyre pressuremonitor If the tyre pressure monitor detects a pressure
loss in one or more tyres, a warning message is shown on the multifunction display. The yellow
tyre pressure warning lamp then lights up:
R If the Please correct tyre pressure
Please correct tyre pressure
message appears on the multifunction dis-
play, the tyre pressure in at least one tyre is
too low. The tyre pressure must be corrected
when the opportunity arises.
R If the Check tyre(s)
Check tyre(s) message appears on
the multifunction display, the tyre pressure in
at least one tyre has dropped significantly.
The tyres must be checked.
R If the Warning tyre defect
Warning tyre defect message
appears on the multifunction display, the tyre
pressure in at least one tyre has dropped sud- denly. The tyres must be checked.
Observe the instructions and safety notes in the display messages in the "Tyres" section
(Y page 273).
If the position of the wheels on the vehicle is
changed, the tyre pressures may be displayed in the wrong positions for a short time. After a few
minutes of driving, this is rectified and the tyre
pressures are displayed in the correct 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 cur-
rently set tyre pressures as the reference values for monitoring. In most cases, the tyre pressure
monitor will automatically detect the new refer- ence values after you have changed the tyre pressure. However, you can also set reference
values manually as described here. The tyre
pressure monitor then monitors the new tyre
pressure values.

The wear patterns on the front and rear tyres
differ depending on the operating conditions.
Interchange the wheels before a clear wear pat-
tern has formed on the tyres. Front tyres typi-
cally wear more on the shoulders, while rear
tyres wear more in the centre.
On vehicles that have front and rear wheels of
the same size, 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 warn-
ing system (Y page 361) or the tyre pressure
monitor (Y page 363). Direction of rotation
Tyres with a specified direction of rotation have additional benefits, e.g. if there is a risk of aqua- planing. These advantages can only be gained if
the tyres are fitted corresponding to the direc-
tion 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

i Apart from some country-specific variants,
vehicles are not equipped with tyre-changing
tools. Some tools for changing a tyre are spe- cific to the vehicle. For more information on
which tools are required to perform a wheel
change on your vehicle, consult a qualified
specialist workshop.
Necessary tyre-changing tools may include,
for example:
R Jack
R wheel chock
R Wheel wrench
R Centring pin
Securing the vehicle against rolling
away If your vehicle is equipped with a wheel chock, it
can be found in the tyre-change tool kit
(Y page 340).
The folding wheel chock is an additional secur-
ing measure to safeguard the vehicle from roll-
ing away, e.g. during a wheel change.

Raising the vehicle G
WARNING
If you do not position the jack correctly at the appropriate jacking point of the vehicle, the
jack could tip over with the vehicle raised.
There is a risk of injury.
Only position the jack at the appropriate jack-
ing point of the vehicle. The base of the jack
must be positioned vertically, directly under
the jacking point of the vehicle.
Observe the following when raising the vehi- cle:
R only use the vehicle-specific jack that has
been tested and approved by Mercedes-Benz
to raise the vehicle. If the jack is used incor-
rectly, it could tip over while the vehicle is
raised.
R the jack is designed only to raise the vehicle
for a short time while a wheel is being
changed. It is not permissible to use it to per- form maintenance work under the vehicle.
R avoid changing the wheel on uphill and down-
hill slopes.
R before raising the vehicle, secure it from roll-
ing 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. use a rubber mat on tiles. 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 do not place your hands or feet under the
raised vehicle.
R do not lie under the raised vehicle.
R do not start the engine when the vehicle is
raised.
R do not open or close a door or the tailgate
when the vehicle is raised.
R make sure that no persons are present in the
vehicle when raising the vehicle. X
Using wheel wrench :, loosen the bolts on
the wheel you wish to change by about one
full turn. Do not unscrew the bolts completely. The jacking points are located just behind the
front wheel arches and just in front of the rear
wheel arches (arrows).
