Tyre monitoring systems
Introduction
The tyre monitor indicator monitors the tyre pressure of each wheel using the
ABS sensors. The ABS sensors monitor the tyre tread perimeter and vibra-
tions of each tire. The tyre monitor indicator warns the driver if it detects a
considerable drop in tyre pressure of one or several tyres while driving. Loss
of tyre pressure will be indicated by the indicator
~ as well as a sound and
sometimes a text message on the screen of the instrument panel. When you
open the driver's door, you will find a label indicating the tyre pressure recom-
mended by the manufacturer for the maximum vehicle load for each tyre
approved for the vehicle in question. By pressing the adjustment button on
the tyre monitoring indicator, you may change the reference pressure for the
tyres so that the tyre pressure to be monitored coincides with actual tyre pres-
sure Ÿpage 248.
Suitable use of the adjustment button Ÿpage 248.

WARNING
Unsuitable handling of the wheels and tyres may lead to sudden tyre pres-
sure losses, to tread separation or even to a blow-out.
xCheck tyre pressures regularly and ensure they are maintained at the
pressures indicated. If the tyre pressure is too low, the tyres could over-
heat, resulting in tread detachment or even burst tyres.
xTyre pressure should be that indicated on the label when the tyres are
cold at all times Ÿpage 328.
xRegularly check the cold inflation pressure of the tyres. If necessary,
change the tyre pressure of the vehicle tyres while they are cold.
xRegularly check your tyres for damage and wear.
xNever exceed the maximum permitted speed or loads specified for the
type of tyre fitted on your vehicle.
WARNING
Incorrect use of the tyre monitoring indicator button could result in the
indicator giving erroneous messages or prevented from indicating the
danger caused by a defective tyre Ÿpage 248.
Caution
xThe tyre valves may be damaged if the cap is not in place. Check that the
caps are identical to the standard caps and have been correctly tightened. Do
not use metal caps Ÿpage 248.
xDo not damage the valves when changing the tyres Ÿpage 248.
For the sake of the environment
Under-inflated tyres lead to increased fuel consumption and tyre wear.
Note
Do not only rely on the tyre monitoring system. Regularly check your tyres to
ensure that the tyre pressure is correct and that the tyres are not damaged
due to puncture, cuts, tears and impacts/dents. Remove objects from the
tyres only when the tyres have not been pierced by these.

Elements of the tyre monitoring indicatorControl lamp
Several warning and control lamps should light up for a few seconds when
the ignition is switched. This signals that the lamp is working properly. They
will switch off after a few seconds.
WARNING
When the tyres are inflated at different pressures or at a pressure that is
too low then a tyre may the damaged resulting in a loss of control of the
vehicle and a serious or mortal accident.
xIf the indicator ~ lights, stop immediately and check the tyres.
xIf the tyres are inflated at different pressures or if a tyre pressure is too
low, this will increase tyre wear, negatively affecting vehicle stability and
increasing braking distances.

Possible cause ŸSolution
~
The tyre pressure of a wheel
has dropped considerably in
relation to the pressure set by
the driver Ÿpage 248.
› Stop the vehicle! Reduce your
speed immediately! Stop the
vehicle safely as soon as possi-
ble. Avoid sudden manoeuvres
and braking!
Check all tyres and pressures.
Replace any damaged tyres.
~System malfunction.
Consult a specialist workshop if
the tyre pressure is correct and
the lamp remains lit after switch-
ing the ignition off and back on
again. Have the system checked
there.
