Tire Pressure Monitoring System
Reset Procedure
Overview
You must carry out the system reset
procedure after each tire replacement or
adjustment of the tire pressures.
To maintain your vehicle load carrying
capability, your vehicle requires different
tire pressures in the front tires compared
to the rear tires. The system will illuminate
the warning lamp at different pressures for
the front and rear tires.
The tires need to be periodically rotated
to provide consistent performance and
maximum tire life, the system needs to
know when the tires have been rotated to
determine which set of tires are on the
front and rear axles. With this information,
the system can detect and correctly warn
of low tire pressures.
Carrying Out the System Reset
Procedure
1. Switch the ignition on.
2. Using the information display control,
navigate to Menu, Vehicle settings,
Driver assist, Tyre Monitor.
3. Press and hold the OK button until
confirmation appears.
Alternatively, if your vehicle has a tire
pressure monitoring system reset button,
press and hold the button until
confirmation appears.
