Operation

Tires and wheels

Run Flat Indicator (Canada only)

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
restricted manner or with a delay

ț

if snow chains are mounted to the
vehicle

ț

in winter road conditions prevail 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)

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 Tire and Load-

ing Information placard. Driving on a signifi-

cantly under-inflated tire causes the tire to

overheat and can lead to tire failure. Un-

der-inflation also reduces fuel efficiency and

tire tread life, and may affect the vehicle’s

handling and stopping ability. Each tire, in-

cluding the spare, should be checked

monthly when cold and set to the recom-

mended tire inflation pressure as specified

in the vehicle placard and owner’s manual.

i

The recommended tire inflation pressures

for your vehicle can be found on the tire placard
located on the driver’s door B-pillar
(

page 296). The tire inflation pressures are

not listed in the owner’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 tire 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.
