• Neutral, Park or Reverse gear positions are selected
• The difference between the actual and set speed is too
great
• When the set speed is above 144 km/h (90 m.p.h.); cruise

Ambient Temperature

The ambient temperature (outside temperature) is displayed
in the top RH corner of the Infortainment 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 7.10).

Tyre Pressure Sensing

Japanese Market
Tyre pressure sensing is not available.
Warning
Tyre pressure sensing is not intended to replace driver
awareness of tyre performance or the need for
recommended weekly checks on tyre condition and
pressure.
Tyre pressure sensing monitors
the vehicle tyre pressures and
feeds-back this information to
the driver.
Each road wheel is installed
with a tyre pressure sensing
device which sends tyre
pressure information to a
control unit.
