Operation
Tires and wheels
Run Flat Indicator*
U.S. vehicles: Run Flat Indicator only avail-
able in conjunction with the MOExtended
system* (
୴ page 326).
While the vehicle is being driven, the Run
Flat Indicator monitors the set tire inflation
pressures by evaluating each wheel’s rota-
tional speed. This allows the system to de-
tect a significant loss of pressure in a tire.
If a wheel’s rotational speed changes due
to falling tire inflation pressure, you will
see a corresponding warning message in
the multifunction display.
The Run Flat Indicator may function in a re-
stricted manner or with a delay
ț if snow chains are mounted to the
vehicle
ț in presence of ice and snow
ț if you are driving on a loose surface
(e.g. sand or gravel)
ț if you are driving in a very sporty man-
ner (involving rapid acceleration or high
speeds in curves)
ț you are driving with the roof loaded or
very heavy cargo
Warning!
G
When the multifunction display shows the
message Tire pressure Check tires ,
one or more of your tires is significantly un-
der-inflated. You should stop and check
your tires as soon as possible, and inflate
them to the proper tire inflation pressure as
indicated on the vehicle’s tire information
placard. Driving on a significantly under-in-
flated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability. Each tire, including the
spare, should be checked monthly when
cold and set to the recommended tire infla-
tion pressure as specified in the vehicle
placard.
i The recommended tire inflation pressures
for your vehicle can be found on the tire placard
located on the driver’s door B-pillar
(
୴ page 316). The tire inflation pressures are
not listed in the operator’s manual.
Warning!
G
The Run Flat Indicator does not provide a
warning for wrongly selected tire inflation
pressures. Always adjust tire inflation pres-
sure according to the placard on the driver’s
door B-pillar or fuel filler flap.
The Run Flat Indicator does not replace reg-
ular checks of the tire inflation pressures
since a gradual pressure loss in more than
one tires cannot be detected by the Run Flat
Indicator.
The Run Flat Indicator is not able to issue a
warning due to a sudden dramatic loss of
tire inflation pressure (e.g. tire blowout
caused by a foreign object). In this case
bring the vehicle to a halt by carefully apply-
ing the brakes and avoiding abrupt steering
maneuvers.
