Preparing the vehicle
Your vehicle may be equipped with:
RMOExtended tires (tires with run-flat
properties) (Ypage 321)
Vehicle preparation is not necessary on
vehicles with MOExtended tires.
Ran emergency spare wheel(Ypage 367)
Information on changing/mountingawheel
(Ypage 357).
XStop the vehicle on solid, non-slippery and
level ground, as far away as possible from
traffic.
XSwitch on the hazard warning lamps.
XSecure the vehicle against rolling away
(Ypage 167).
XIf possible, bring the front wheels into the
straight-ahead position.
XVehicles with AIRMATIC: make sure that
"normal" level is selected (Ypage 189).
XSwitch off the engine.
XVehicles without KEYLESS-GO:remove
the SmartKey from the ignition lock.
XVehicles with KEYLESS-GO:open the
driver's door.
The on-board electronicsnow have status
0.This is the same as the SmartKey having
been removed.
XVehicles with KEYLESS-GO:remove the
Start/Stop button from the ignition lock
(Ypage 147).
XAll occupants must get out of the vehicle.
Make sure that they are not endangered as
they do so.
XMake sure that no one is near the danger
area whileawheel is being changed.
Anyone who is not directly assisting in the
wheel change should, for example, stand
behind the barrier.
XGet out of the vehicle. Pay attention to
traffic conditionswhen doing so.
XClose the driver's door.
MOExtended tires (tires with run-flat
properties)
General notes
With MOExtended tires (tires with run flat
characteristics), you can continue to drive
your vehicle even if there isatotal loss of
pressure in one or more tires. The affected
tire must not show any clearly visible damage.
You can recognizeMOExtended tires by the
MOExtended marking which appears on the
sidewall of the tire. You will find this marking
next to the tire size designation, the load-
bearing capacity and the speed index
(Ypage 351).
MOExtended tires may only be used in
conjunction with an active tire pressure loss
warning system or with an active tire pressure
monitor.
If the pressureloss warning message
appearsinthe multifunction display:
RObserve the instructions in the display
messages (Ypage 258).
RCheck the tire for damage.
RIf driving on, observe the following notes.
The maximum driving distance is
approximately 50 miles (80 km) when the
vehicle is partially laden and approximately
18 miles (30 km) when the vehicle is fully
laden.

workshop.
When parking your vehicle,makesure that
thetires do notget deformed by the curb or
other obstacles. If it is necessary to drive over
curbs, speed humps or similar elevations, try
to do so slowly and at an obtuse angle.
Otherwise, the tires, particularly the
sidewalls, may be damaged.
Regular checking of wheels and tires
GWARNING
Damaged tires can cause tire inflation
pressure loss. Asaresult, you could lose
control of your vehicle. There isarisk of
accident.
Check the tires regularly for signs of damage
and replace any damaged tires immediately.
Regularly checkthe wheels and tires of your
vehicle for damage at least onceamonth, as
well as after driving off-road or on rough
roads. Damaged wheels can causealoss of
tire pressure. Pay particular attention to
damage such as:
Rcuts in the tires
Rpunctures
Rtears in the tires
Rbulges on tires
Rdeformation or severe corrosion on wheels
Regularly check the tire tread depth and the
condition of the tread across the whole width
of the tire (Ypage 335). If necessary, turn
the front wheels to full lock in order to inspect
the inner side of the tire surface.
All wheels must haveavalve cap to protect
the valve against dirt and moisture. Do not
mount anything onto the valve other than the
standard valve cap or other valve caps
approved by Mercedes-Benzfor your vehicle.
Do not use any other valve caps or systems,
e.g. tire pressure monitoring systems.
Regularly check the pressure of all the tires
particularly prior to long trips. Adjust the tire
pressure as necessary (Ypage 338).
Observe the notes on the emergencyspare
wheel (Ypage 367).
The service life of tires depends, among other
things, on the following factors:
RDrivingstyle
RTire pressure
RDistance covered
Important safety notes on the tire
tread
GWARNING
Insufficient tire tread will reduce tire traction.
The tire is no longer able to dissipate water.
This means that on wet road surfaces, the risk
of hydroplaning increases, in particular where
speed is not adapted to suit the driving
conditions. There isarisk of accident.
If the tire pressure is too high or too low, tires
may exhibit different levels of wear at
different locations on the tire tread. Thus, you
should regularly check the tread depth and
the condition of the tread across the entire
width of all tires.
Minimum tire tread depth for:
RSummer tires:in (3 mm)
RM+S tires:in (4 mm)
For safety reasons, replace the tires before
the legally prescribed limit for the minimum
tire tread depth is reached.
Operation335
Wheels and tires
Z

The tire pressure monitor hasayellow
warning lamp in the instrument cluster for
indicatingapressure loss or malfunction.
Whether the warning lamp flashes or lights up
indicates whetheratire pressure is too low or
the tire pressure monitor is malfunctioning:
Rif the warning lamp is lit continuously, the
tire pressure on one or more tires is
significantly too low. The tire pressure
monitor is not malfunctioning.
Rif the warning lamp flashes for around a
minute and then remains lit constantly, the
tire pressure monitor is malfunctioning.
If the tire pressure monitor is malfunctioning,
it may take more than ten minutes for the tire
pressure warning lamp to inform you of the
malfunction by flashing for approximately one
minute and then remaining lit. When the
malfunction has been rectified, the tire
pressure warning lamp goes out afterafew
minutes of driving.
The tire pressure values indicated by the on-
board computer may differ from those
measured atagas station withapressure
gauge. The tire pressures shown by the on-
board computer refer to those measured at
sea level. At high altitudes, the tire pressure
values indicated byapressure gauge are
higher than those shown by the on-board
computer.Inthis case, do not reduce the tire
pressures.
The operation of the tire pressure monitor can
be affected by interference from radio
transmitting equipment (e.g. radio
headphones, two-way radios) that may be
being operated in or near the vehicle.

Afterateach-in process, the tire pressure
monitor automatically detects new wheels or
new sensors. As long asaclear allocation of
the tire pressure value to the individual
wheels is not possible, theTire Pressure
Monitor Activedisplaymessage is shown
instead of the tire pressure display. The tire
pressures are already being monitored.
iIf an emergency spare wheel is mounted,
the system may continue to show the tire
pressure of the wheel that has been
removed forafew minutes. If this occurs,
note that the value displayed for the
position where the spare wheel is mounted
is not the same as the current tire pressure
of the emergency spare wheel.
