in the multifunction display:
Robserve the instructions in the displaym es-
sages (Ypage 211).
Rcheck the tire for damage
Rif driving on, observe the following notes
The driving distance possible in run-flat mode is
approximately 50 miles (80 km) when the vehi-
cle is partiallyl aden. When the vehicle is fully
laden it is approximately 19 miles (30 km).
In addition to the vehicle load, the driving dis-
tance possible depends upon:
Rvehicle speed
Rroad condition
Routside temperature
The driving distance possible in run-flat mode
may be reduced by extreme driving conditions
or maneuvers, or it can be increased through a
moderate style of driving.
The driving distance possible in run-flat mode is
counted from the moment the tire pressure loss
warning appears in the multifunction display.
You must not exceed amaximum speed of
50 mph (80 km/h).
When replacing one or all tires, please observe
the following specifications for your vehicle's
tires:
Rsize
Rtype and
Rthe "MOExtended" marking
If at ire has gone flat and cannot be replaced
with aMOExtended tire, astandard tire may be
used as atemporary measure. Make sure that
you use the proper size and type (summer or
winter tire).
Vehicles equipped with MOExtended tires are
not equipped with aTIREFIT kit at the factory. It
is therefore recommended that you additionally
equip your vehicle with aTIREFIT kit if you mount
tires that do not feature run-flat properties, e.g.
winter tires. ATIREFIT kit may be obtained from
aq ualified specialist workshop.
Important safety notes
GWARNING
When driving in emergency mode, the driving
characteristics deteriorate, e.g. when corner-
ing, accelerating quickly and when braking.
There is arisk of an accident.

'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

shown in theServ.menu of the multifunction
display, see illustration (example).
For information on the message display, refer to
the "Checking the tire pressure electronically"
section (
Ypage 296).
Important safety notes
GWARNING
Each tire, including the spare (if provided),
should be checked 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-pillar or the tire pres-
sure label on the inside of the fuel filler flap. If
your vehicle has tires of adifferent size than
the size indicated on the Tire and Loading
Information placard or, if available, the tire
pressure label,y ou should determine the
proper tire pressure for those tires.
As an added safety feature, your vehicle has
been equipped with atire pressure monitoring
system (TPMS) that illuminates alow tire pres-
sure telltale when one or more of your tires
are significantly underinflated. Accordingly,
when the low tire pressure telltale lights up,
you should stop and check your tires as soon
as possible,a nd inflate them to the proper
pressure. Driving on asignificantly underin-
flated tire causes the tire to overheat and can
lead to tire 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 illumination of the 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
will flash for approximately aminute and then
remain continuously illuminated. This
sequence will be repeated 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 able to detect
or signal low tire pressure as intended.
TPMS malfunctions may occur for avariety of
reasons, including the installation of incom-
patible replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioningp roperly. Always check the
TPMS malfunction telltale after replacing one
or more tires or wheels on your vehicle to
ensure that the replacement or alternate Tires
and wheels allow 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 290). Note that the correct tire pressure
for the current operating situation must first be
taught-in to the tire pressure monitor. If asub-
stantial loss of pressure occurs, the warning
threshold for the warning message is aligned to
the taught-in reference values. Restart the tire
pressure monitor after adjusting the pressure of
the cold tires (
Ypage 297). The current pres-
sures are saved as new reference values. As a
result, awarning message will appearift he 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 290).
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

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.
