Tyre Pressure Monitoring System
*
(TPMS)
TPMS can not replace routine maintenance
and checks of the tyre condition and
pressure.
Note: TPMS only warns of low tyre pressures, it does
not re-inflate the tire.
System Operation
The system is controlled by the SCS system,
which constantly monitors the speed of each wheel. If,
during normal driving conditions with the brakes not
applied, the SCS detects that one wheel is rotating faster
than the others, it deduces that the pressure of that tyre
has fallen below the predefined limit of the system. As
a result, the warning light on the instrument pack will
illuminate (always yellow).
Check your tyres at the earliest opportunity and reinflate
to the correct pressures. Refer to 'Tyre Pressures (Cold)'.
STARTING & DRIVING
System Malfunction
This system is self-monitoring, if a malfunction is detected,
the TPMS warning lamp (yellow) on the instrument pack
will flash for 90 seconds first and then illuminate.
Note: When a puncture is detected, the system will
require some time to analise information prior to
illuminating the warning lamp.
Under certain conditions the warning light may illuminate
when a fault is not present. these conditions include:
• Driving on icy or wet surfaces.
• Front axle slip or excessive lateral acceleration.
• Snow chains fitted.
• A non recommended tyre fitted (including spare tyre).
• TPMS not reset after tyre replacement.
• TPMS not reset after tyre pressure adjustment.
• Rough terrain driving for excessive periods.
• Bending or mountain type terrain driving for excessive
periods.
• Excessive luggage weight change from when last reset
carried out.
• TPMS will not respond immediately if a tyre 'blows out'.
