'OK'toRestartmessage in the multifunction
displayint heServ.menu. Information on the
message displayc an be found in the "Restarting
the tire pressure loss warning" section
(
Ypage 294).
Important safety notes
The tire pressure warning system does not warn
you of an incorrectly set tire pressure. Observe
the notes on the recommended tire pressure
(
Ypage 290).
The tire pressure loss warning does not replace
the need to regularly check the tire pressure. An
even loss of pressure on several tires at the
same time cannot be detected by the tire pres-
sure loss warning system.
The tire pressure monitor is not able to warn you
of as udden loss of pressure, e.g. if the tire is
penetrated by aforeign object. In the event of a
sudden loss of pressure, bring the vehicle to a
halt by braking carefully.A void abrupt steering
movements.
The function of the tire pressure loss warning
system is limited or delayed if:
Rsnow chains are mounted on your vehicle's
tires.
Rroad conditions are wintry.
Ryou are driving on sand or gravel.
Ryou adopt avery sporty driving style (corner-
ing at high speeds or driving with high rates of acceleration).
Ryou are driving with aheavy load (in the vehi-
cle or on the roof)
Restarting the tire pressure loss warn-
ing system
Restart the tire pressure loss warning system if you have:
Rchanged the tire pressure
Rchanged the wheels or tires
Rmounted new wheels or tires
XBefore restarting, make sure that the tire
pressures are set properly on all four tires for
the respective operating conditions.
The recommended tire pressure can be found
on the Tire and Loading Information placard
on the B-pillar. Additionally,at ire pressure
table is attached to the fuel filler flap. The tire
pressure loss warning system can only give
reliable warnings if you have set the correct tire pressure. If an incorrect tire pressure is
set, these incorrect valuesw
ill be monitored.
XAlso observe the notes in the section on tire
pressures (Ypage 290).
XMake sure that the SmartKey is in position 2
in the ignition lock (Ypage 122).

Tire pressure monitor (Canada only)
General notes
If at ire pressure monitor is installed, the vehi-
cle's wheels have sensors that monitor the tire
pressures in all four tires. The tire pressure mon-
itor warns you if the pressure drops in one or
more of the tires. The tire pressure monitor only
functions if the corresponding sensors are
installed in all wheels.
Information on tire pressures is displayed in the
multifunction display. After afew minutes of
driving, the current tire pressure of each tire is
294Tire pressure
Wheels and tires

The tire pressure monitor hasayellow warning
lamp in the instrument cluster for indicating
pressure loss or amalfunction. Whether the
warning lamp flashes or lights up indicates
whether atire 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 mal- functioning.
Rif the warning lamp flashes for around a
minute and then remains lit constantly, the
tire pressure monitor is malfunctioning.
In addition to the warning lamp, amessage
appears in the multifunction display.O bserve
the information on display messages
(
Ypage 211).
It may take up to ten minutes for amalfunction
of the tire pressure monitor to be indicated. A
malfunction will be indicated by the tire pres-
sure warning lamp flashing for approximately
one minute and then remaining lit. When the
malfunction has been rectified, the tire pressure
warning lamp goes out after afew minutes of
driving.
The tire pressure values indicated by the on-
board computer may differ from those meas-
ured at agas station with apressure 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 by a
pressure gauge are higher than those shown by the on-board computer. In this case, do not
reduce the tire pressures.
The operation of the tire pressure monitor can
be affected by interferenc efrom radio transmit-
ting equipment (e.g. radio headphones, two-way
radios) that may be being operated in or near the vehicle.

If an emergencys pare wheel is mounted, the
system may continue to show the tire pressure
of the wheel that has been removed for afew
minutes. If this occurs, notet hat the value dis-
played for the position where the spare wheel is
mounted is not the same as the current tire
pressure of the emergencys pare wheel.

sages
If the tire pressure monitor detect sapressure
loss in one or more tires, awarning message is
shown in the multifunction display.T he yellow

RIf the Please Correct Tire Pressuremessage appears in the multifunction display,
the tire pressure in at least one tire is too low.
The tire pressure must be corrected when the
opportunit yarises.
RIf the Check Tire Pressuremessage
appears in the multifunction display,t he tire
pressure in one or more tires has dropped
significantly. The tires must be checked.
RIf the TirePressureWarningTireFail‐uremessage appears, the tire pressure in one
or more tires has dropped suddenly. The tires
must be checked.
Observe the instructions and safety notes in the
display messages in the "Tires" section
(
Ypage 211).
If the wheel positions on the vehicle are rotated,
the tire pressures may be displayed for the
wrong positions for ashort time. This is rectified
after afew minutes of driving, and the tire pres-
sures are displayed for the correctp ositions.

Restarting the tire pressure monitor
Whenyourestart the tire pressure monitor, all
existing warning messages are deleted and the
warning lamps go out. The monitor uses the cur-
rentlys et tire pressures as the reference values
for monitoring. In most cases, the tire pressure
monitor will automaticall ydetect the new refer-
ence value safteryou have changed the tire
pressure. However, yo ucan also set reference
value smanually as described here. The tire
pressure monitor then monitors the new tire
pressure values.

Tire-mounting tools should not be used near
the valve. This could damage the electronic
components.
Only have tires changed ataqualified spe-
cialist workshop.
Observe the instructions and safety notes in the
"Changing awheel" section (
Ypage 307).
The wear pattern sonthe front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before aclear wear pattern
has formed on the tires. Frontt ires typically
wear more on the shoulders and the rear tires in
the center.
On vehicles that have the same size front and
rear wheels, you can rotat ethe wheels accord-
ing to the intervals in the tire manufacturer's
warranty book in your vehicle documents. If no
warranty book is available, the tires should be
rotated every 3,000 to 6,000 miles (5,000 to
10,000k m).D ependin gontire wear, this may
be required earlier. Do not change the direction
of wheel rotation.
Clean the contact surfaces of the wheel and the brake disc thoroughly every time awheel is rota-
ted. Check the tire pressure and, if necessary,
restart the tire pressure loss warning system
(Canada only) or the tire pressure monitor (USA
only).
Direction of rotation
Tires with aspecified direction of rotation have
additional benefits ,e.g. if there is arisk of hydro-
planing. These advantages can only be gained if
the tires are installed corresponding to the
direction of rotation.
An arrow on the sidewall of the tire indicates its
correctd irection of rotation.
Storing wheels

dry and preferably dark place. Protectt he tires
from oil, grease, gasoline and diesel.
