Ambient Temperature

The ambient temperature (outside temperature) is displayed
in the top RH corner of the Infotainment centre display.
If the vehicle has been travelling a while and then is stopped
in a shaded / enclosed area the ambient temperature may
rise, this is due to the heat from the engine bay. The ambient
temperature display will reflect the true ambient temperature
once the vehicle is moving again or the engine bay cools
down.
If required the display units can be changed from °C to °F or
°F to °C (Refer to 'Display Units', page 7.8)

Tire Pressure Monitoring

Warning
Tire pressure sensing is not intended to replace driver
awareness of tire performance or the need for
recommended weekly checks on tire condition and
pressure.
Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label (if your vehicle
has tires of a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those tires).
