General Points
To ensure the satisfactory operation of
the climate control system, note the
following points:
" Ensure that the external grille at the
base of the windscreen, which
provides fresh air for the climate
control system, is kept clear of leaves,
snow or obstructions.
" Air ducts under the front seats supply
the rear passenger footwells (refer to
illustration on page 131). Objects or
material placed under the seats may
block or obstruct the open ducts.
" The external air intake to the air
conditioner/heater system is fitted
with a filter. Ensure that the filter is
changed at the specified service
intervals to maintain efficient
operation.
" If the air conditioning system is not
used frequently, it should be run
briefly at least once each week, with a
cold setting, to prevent the seals from
drying out with subsequent refrigerant
leaks.
" Moisture removed from the air by the
air conditioning unit is discharged
onto the road underneath the vehicle.
After stopping, puddles of water may
form underneath the vehicle: this is
normal.

Air Distribution
The illustration shows the location of the
air vents within the vehicle.
On vehicles fitted with automatic climate
control, the appropriate air distribution is
selected automatically when operating in
AUTO mode.
On all climate control systems,
the distribution of air between the screen,
fascia and floor level can be manually
selected using the panel controls.
The airflow from the fascia face level
vents is regulated using thumbwheel
controls and adjustable direction vanes.
