Tire pressure loss warning system
(Canada only)
General notes
While the vehicle is in motion, the tire pressure
loss warning system monitors the set tire pres-
sure 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.
You can recognize the tire pressure loss warning
by the Run Flat Indicator Active
Press
'OK' to Restart message which appears in
the Service
menu of the multifunction display.
Information on the message display can be
found in the "Restarting the tire pressure loss
warning system" section (
Y page 394).
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
(
Y page 387).
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 a sudden loss of pressure, e.g. if the tire is
penetrated by a foreign object. In the event of a
sudden loss of pressure, bring the vehicle to a
halt by braking carefully. Avoid abrupt steering
movements.
The function of the tire pressure loss warning
system is limited or delayed if:
R
snow chains are mounted on your vehicle's
tires.
R
road conditions are wintry.
R
you are driving on sand or gravel.
R
you adopt a very sporty driving style (corner-
ing at high speeds or driving with high rates of
acceleration).
R
you are driving with a heavy load (in the vehi-
cle or on the roof).
