Heating and ventilation
Automatic system
Manual system
These are the primary functions of the heating
and ventilation syst em. Dependent upon
specification, the contro l panel may differ from
those shown.
Air conditioning
Air conditioning is an in tegral part of the
heating and ventilati on system, providing
cooled and dehumidifie d air for occupant
comfort. The dry airflow is effective in
preventing misting of windows and is also
beneficial at low external temperatures.
Air conditioning is automatically switched on
and controlled whenever the system is not
operating in ECON mode. Auto mode (Automatic systems)
Press AUTO to select automatic
operation of the system, both LEDs
in the switch will illuminate.
The system will adjust the heat
output, blower speed, air intake and airflow
distribution to maintain the selected
temperature(s) and re duce misting without
further adjustments.

External water deposits
The air conditioning system removes
moisture from the ai r and deposits excess
water beneath the vehicl e. Puddles may form,
but this is no cause for concern.

Tachometer
Indicates engine spee d in revolutions per
minute (RPM) x 1000.
Temperature gauge
If the pointer moves onto the red line and the
red warning indicator illu minates severe engine
damage can occur.
If the engine overheats, stop the vehicle as
soon as safety pe rmits. Switch the engine off
and allow it to cool down. If the problem
reoccurs, seek qualified assistance before
continuing.
Note: If engine temperatur e rises to the point
where overheating may occur, there may be a
noticeable reduction in engine power, and the
air conditioning may cease operation. This is a
normal operating strate gy to reduce load on
the engine and assist with cooling.
Fuel gauge
Once the fuel level has dropped to the point
where the range is approximately 80 km (50
miles) the low fuel warning indicator will
illuminate.
As a reminder for the location of the fuel filler,
there is an arrow next to the fuel pump symbol
which points to the releva nt side of the vehicle.
Speedometer
Indicates road speed. Odometer
Indicates the total distance which the vehicle
has travelled.
Trip recorder
Indicates the distance travelled since the last
reset, and can be used to measure the distance
of individual journeys.
Trip recorder reset button
Resets the distance shown on the trip recorder
to zero.
Note: Once the trip recorder has been reset to
zero, the previously recorded distance will be
lost.
Gear selector mode and positiondisplay
Displays the currently selected gear on
vehicle's fitted with automatic transmission.
Main message centre
Displays warning, and information messages.
See INFORMATION MESSAGES (page 99).
Warning indicator panel (fitted in place of
main message centre)
If a main message centre is not fitted, the
warning indicator pane l will provide system
status information.
Warning indicator panel
The warning indicator panel will provide
system status information.
CAUTION
Serious engine damage can occur if the
vehicle is driven whilst the engine is
overheating.
CAUTION
Never allow the vehicle to run out of
fuel. The resulting mis-fire may cause
serious damage to the catalytic
convertor.
