Tire Pressure Indicator
If an under-inflated tire is detected by the system, the TPMS
symbol is solidly illuminated.
The message centre will also display one of the below messages:
• Please Rectify Tire Pressures: At least one tire has too low a
pressure. Tire pressures should be checked and corrected
when possible.
• Check Tire(s): At least one tire has significantly low pressure.
The tire pressures must be checked and corrected as soon as
possible.
• Warning Tire Defect: At least one tire has lost pressure very
suddenly. The vehicle should be stopped as safely as possible
and the tires checked.
Once the message has been acknowledged an image of the
vehicle will be displayed in the message centre showing which
tire(s) have low or high air pressure and the current tire pressure.
When the tire pressure indicator comes ON, stop and check your
tires as soon as possible, and inflate or deflate them to the correct
pressure.
Warning: When a tire pressure warning is detected,
reduce the vehicle speed to a safe level. Stop in a safe and
convenient place and inspect the tire(s).
The tire pressures may be displayed in the wrong positions for
a short time if the wheels have been moved on the vehicle. After
a few minutes of driving, the TPMS will calibrate and the tire
pressures are displayed in the correct positions.

Driving
TPMS Reset
All warning messages are erased and warning lamps go out
when the TPMS is reset. The TPMS will use the new tire pressure
values as reference values.
To reset the TPMS tire pressure values:
1. Use the right scroll wheel on the steering wheel to navigate
to Service.
2. Navigate to Tire Pressure.
3. Select Use Current Pressures as New Reference Values.
4. The TPMS will now reset. After a short period of driving, the
system checks if the tire pressures are within the specified
range. The new tire pressures are then used as the new
reference values.
