Important safety notes
GWARNING
Each tire, including the spare (if provided),
shoul dbec hecked at least once every two
weeks when cold and inflated to the pressure recommended by the vehicle manufacturer
on the Tire and Loading Information placard
on the driver's door B-pillaro rthe tire pres-
sure label on the inside of the fuel fillerf lap. If
you rvehicle has tires of adifferent size than
the size indicated on the Tire and Loading
Information placard or, if available, the tire
pressure label, you shoul ddetermine the
proper tire pressure for those tires.
As an adde dsafety feature, you rvehicle has
been equipped with atire pressure monitoring
system (TPMS) that illuminates alow tire pres-
sure telltal ewhen one or more of you rtires
are significantly underinflated. Accordingly,
when the low tire pressure telltal elights up,
you shoul dstop and check you rtires as soon
as possible, and inflate them to the proper
pressure. Driving on asignificantly underin-
flated tire cause sthe tire to overheata nd can
leadtot ire failure.
Underinflation also reduces fuel efficiency
and tire tread life, and may affect the vehicle's
handling and stopping ability. Please note that the TPMS is not asubstitute for proper tire
maintenance, and it is the driver's responsi-
bility to maintain correct tire pressure, even if
underinflation has not reached the level to
trigger illuminatio nofthe TPMS low tire pres-
sure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale. When the sys-
tem detects amalfunction, the warning lamp
wil lflash for approximately aminute and then
remain continuously illuminated .This
sequence wil lberepeated every time the vehi-
cle is started as long as the malfunction
exists. When the malfunction indicator is illu-
minated, the system may not be abl etodetect
or signal low tire pressure as intended.
TPMS malfunctions may occur for avariety of
reasons, including the installation of incom-
patibl ereplacement or alternate tires or
wheel sonthe vehicle that prevent the TPMS
from functioning properly. Alway scheck the
TPMS malfunction telltal eafter replacing one
or more tires or wheel sonyourv ehicle to
ensure that the replacement or alternate Tires
and wheelsa llow the TPMS to continue to
function properly.
It is the driver's responsibility to set the tire
pressure to that recommended for cold tires
which is suitable for the operating situation
(
Ypage 319). Note that the correct tire pressure
for the current operating situation must first be
taught-in to the tire pressure monitor. If there is
as ubstantial loss of pressure, the warning
threshold for the warning messag eisaligned to
the reference values taught-in. Restart the tire
pressure monitor after adjusting the pressure of
the cold tires (
Ypage 325). The current pres-
sures are saved as new reference values. As a
result, awarning messag ewillappear if the tire
pressure drops significantly.
The tire pressure monitor does not warn you of
an incorrectly set tire pressure. Observe the
notes on the recommended tire pressure
(
Ypage 319).
The tire pressure monitor is not abl etowarn you
of as udden loss of pressure, e.g. if the tire is
penetrated by aforeign object. In the event of a
su

dden loss of pressure, bring the vehicle to a
halt by braking carefully. Avoid abrupt steering
movements.
324Tire pressure
Wheelsa nd 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 241).
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.

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
tire pressure warning lamp then lights up.
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 Tiresmessage appears in the
multifunction display,t he tire pressure in one
or more tires has dropped significantly. The
tires must be checked.
RIf the WarningTireMalfunctionmessage
appears in the multifunction display,t he tire
pressure in one or more tires has dropped
suddenly. The tires must be checked.
Be sure to observe the instructions and safety
notes in the display messages in the "Tires" sec- tion (
Ypage 241).
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 pressuremonitor
When you restart the tire pressure monitor, all
existin gwarning messages are deleted and the
warning lamps go out. The monitor uses the cur-
rently set tire pressures as the reference values

PSI (pounds per squareinch)
Astandard unit of measure for tire pressure.
Aspect ratio
Relationship between tire height and tire width
in percent.
Tire pressure
This is pressure inside the tire applying an out-
ward force to each square inch of the tire's sur-
face. The tire pressure is specified in pounds per
square inch (psi), in kilopascal (kPa) or in bar.
The tire pressure should only be corrected when
the tires are cold.
Cold tire pressure
The tires are cold:
Rif the vehicle has been parked with the tires
out of direct sunlight for at least three hours
and
Rif the vehicle has not been driven further than
1m ile (1.6 km)
Tread
The part of the tire that comes into contact with
the road.
Bead
The tire bead ensures that the tire sits securely
on the wheel. There are several steel wires in the
bead to prevent the tire from coming loose from
the wheel rim.
Sidewall
The part of the tire between the tread and the
bead.
Weight of optional extras
The combined weight of those optional extras
that weigh more than the replaced standard
parts and more than 5lbs (2.3 kg). These
optional extras, such as high-performance
brakes, level control, aroof rack or ahigh-per-
formanceb attery, are not included in the curb
weight and the weight of the accessories.
TIN (Tire Identification Number)
This is aunique identifier which can be used by
at ire manufacturer to identify tires, for example
for aproduct recall, and thus identify the pur-
chasers. The TIN is made up of the manufactur-
er's identity code, tire size, tire type code and
the manufacturing date.
Load bearing index
The load bearing index (also load index) is acode
that contains the maximum load bearing capa-
city of atire.
Traction
Traction is the result of friction between the tires
and the road surface.
Treadwear indicators
Narrow bars (tread wear bars) that are distrib-
uted over the tire tread. If the tire tread is level
with the bars, the wear limit of áin (1.6 mm)
has been reached.
Occupant distribution
The distribution of occupants in avehicle at their
designated seating positions.
Total load limit
Nominal load and luggage load plus 68 kg
(15 0lbs)m ultiplied by the number of seats in
the vehicle.

The "Breakdown assistance" section
(Ypage 300) contains information and notes on
how to deal with aflat tire. Information on driv-
ing with MOExtended tires in the event of aflat
tire can be found under "MOExtended tires (tires
with run-flat characteristics" (
Ypage 301).
Rotating the wheels
GWARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
the wheels or tires have different dimensions. The wheel brakes or suspension components
may also be damaged. There is arisk of acci-
dent.
Rotate front and rear wheels only if the wheels and tires are of the same dimensions.
