TPMS tyre location indicator

Tyre valve with sensor
The tyre pressure monitoring system monitors the
tyre pressure of the four wheels while the vehicle is
in motion. Following a loss in pressure, the system
will warn the driver using a visual warning. Each
TPMS sensor
jA has a registered wheel location
and sends pressure and temperature data via radio
to a receiver inside the vehicle.
Each tyre, including the spare (where fitted), should
be checked monthly when cold and inflated to the
inflation pressure recommended by the vehicle
manufacturer on the vehicle placard or tyre inflation
pressure label. (If your vehicle has tyres of a differ-
ent size than the size indicated on the vehicle plac-
ard or tyre inflation pressure label, you should deter-
mine the proper tyre inflation pressure for those
tyres.)
The Tyre Pressure Monitoring System (TPMS) con-
trols the TPMS indicator light
ja , which will illumi-
nate when one or more tyres are significantly under-
inflated. A warning and tyre location indicator
jb
will also appear in the vehicle information display to
identify the tyre or tyres with low pressure.
If you now press the <ENTER> switch on the steer-
ing wheel, a further screen is displayed to tell you
the tyre pressure of all four tyres.
Accordingly, when the TPMS indicator light illumi-
nates, safely stop the vehicle to check the tyres as
soon as possible and inflate the tyres to the proper
pressure. Driving on a significantly under-inflated
tyre causes the tyre to overheat and can lead to tyre
failure. Under-inflation also reduces fuel efficiency
and tyre tread life which may affect the vehicle’s
handling and stopping ability.
NOTE
The TPMS is not a substitute for proper tyre main-
tenance. It is the driver’s responsibility to main-
tain correct tyre pressure, even if under-inflation
has not reached the level to trigger the illumina-
tion of the TPMS indicator light
ja.
The TPMS indicator light flashes for a short period
and then turns on continuously if the system is not
operating properly. This sequence will continue
upon subsequent vehicle start-ups as long as the
malfunction exists (missing or faulty TPMS sensor
or TPMS system malfunction). When the malfunc-
tion warning light is illuminated, the system may not
