Ambient Temperature
The external ambient air temperature is measured by a sensor located on the right hand side of the bonnet locking
platform, behind the front grill. The sensor is connected to the HEVAC module. The HEVAC module outputs temperature
messages on the CAN bus which are used by the instrument cluster to display the current ambient temperature.
The message center displays the ambient temperature in the top right hand corner of the LCD display. The temperature is
displayed until the message center is required to display system information. When system information has been
displayed, the ambient temperature will reappear. The temperature is displayed in ºF or ºC depending the market
configuration of the vehicle. The driver can also change the temperature reading using the 'Customer Settings' function.
Cold Warning Indication
When the ambient temperature is being displayed, if the temperature falls to 4ºC (39.2ºF) or below, the cold warning
symbol will display. The cold warning symbol is in the form of a snow flake and will flash on and off, five times at a
frequency of 2Hz. An audible warning will also be emitted by the instrument cluster to alert the driver. After the fifth flash
of the symbol, the display will continue to display the snow flake symbol in place of 'EXT' until a temperature of 6°C (42.8°
F) or higher is measured.
The cold warning will only be displayed once during an ignition cycle. If the ambient temperature rises to 6ºC (42.8ºF) or
above and then subsequently falls to 4ºC (39.2ºF) or below during the same ignition cycle, the warning will be repeated.
If the display mode changes to a mode which does not display the ambient temperature during the warning period, the
