Tire pressure loss warning system(Canada only)
Important safety notes
While the vehicle is in motion, the tire pressure loss warning system monitors the set tire pressure using the rotational speed of the wheels. This enables the system to detect significant pressure loss in a tire. If the speed of rotation of a wheel changes as a result of a loss of pressure, a corresponding warning message will appear in the multifunction display.
WARNING
When the multifunction display shows the
message Tire Pressure Check Tires, one
or more of your tires are significantly
underinflated. 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 and Loading
Information placard or on the tire inflation
pressure label.
Driving on a significantly underinflated 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.
Each tire, including the spare, should be
checked at least once a month when cold.
Inflate the tires to the recommended tire
inflation pressure as specified on
• the Tire and Loading Information
placard on
the driver's door B-pillar
or
• the tire inflation pressure label
located on
the inside of the fuel filler flap
WARNING
The tire pressure loss warning system does
not provide a warning for wrongly selected tire
inflation pressures. Always adjust tire
inflation pressure according to the Tire and
Loading Information placard on the driver's
door B-pillar or on the tire inflation pressure
label located on the inside of the fuel filler flap.
The tire pressure loss warning system does
not replace regular checks of the tire inflation
pressures since a gradual pressure loss in
more than one tire cannot be detected by the
tire pressure loss warning system.
The tire pressure loss warning system 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
applying the brakes and avoiding abrupt
steering maneuvers.
The function of the tire pressure loss warning system is limited or delayed if:
• snow chains are mounted to your
vehicle's
tires.
• road conditions are wintry.
• you are driving on sand or gravel.
• you adopt a very sporty driving style
(cornering at high speeds or driving with
high rates of acceleration).
• you are towing a very heavy or large
trailer.
• you are driving with a heavy load (in the
vehicle or on the roof).
Restarting the tire pressure loss warning system
Restart the tire pressure loss warning system if you have:
• changed the tire pressure
• changed the wheels or tires
• mount new wheels or tires
► Before restarting, consult the Tire and Loading Information placard on the B-pillar on the driver's side or the tire pressure table on the inside of the fuel filler flap to ensure the tire pressure in all four tires is set correctly for the current operating conditions.
► Observe the notes in the section on tire pressures.
WARNING
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 values will be monitored.
A tire with insufficient pressure results in
vehicle instability when driving, thus
increasing the risk of an accident.
► Make sure that the SmartKey is in position 2 in the ignition lock.
► Press and hold the button on the multifunction steering wheel until the standard display appears in the multifunction display.
► Press the button until the Run Flat Indicator Active Menu: RButton message appears in the multifunction display.
► Press the reset button on the instrument cluster.
The Restart Run Flat Indicator? message appears in the multifunction display.
If you wish to confirm the restart:
► Press the button.
The Run Flat Indicator Restarted message appears in the multifunction display.
After a teach-in period, the tire pressure loss warning system will monitor the set tire pressures of all four tires.
If you wish to cancel the restart:
► Press the
button.
or
► Wait until the Restart Run Flat
Indicator? message goes out.
The tire pressure values stored at the last restart will continue to be monitored.
