A- Tailgate window wiper/
washer (wagon)

The tailgate window wiper/
washer is operated by a switch
at the end of the wiper level.
1. The wiper operates
continuously.
2. Intermittent position: the
wiper strokes approximately
every 10 seconds.
3. Tailgate washer (note that the
wiper also operates when this
button is depressed): after the
button is released the wiper
strokes 2-3 additional times
before stopping.
The electrical circuit is
protected by fuse 19, located in
the central electrical unit. See
the section entitled "Fuses". B- Electrically operated
sun roof (certain models)

The sun roof can be operated in
two ways; as a conventional
sliding roof; or the rear edge can
be raised to provide increased
ventilation. On models equipped
with the power glass sun roof, a
manually operated sun shade is
also provided.
See page 49 for operating
instructions.

NOTE:In case of sun roof
malfunction, see page 49.
Cruise control pg. 24
NOTE:
When driving in hilly terrain,
the gearbox may tend to jump
between different gears. This
can be avoided by selecting
gear selector position 3
(intermediate position).
Normally, the (E)conomy
mode should be used when
the cruise control is engaged.

Acceleration
Momentary acceleration, such
as for passing, does not
interrupt cruise control
operation. The previously
selected speed will be
maintained without having to
set the switch to RESUME.
To disengage the cruise

control system:
set switch (B) to OFF,
depress the brake pedal or
move the gear selector to
position N. Switching off the
starting (ignition) switch will
automatically disengage the
cruise control system.
WARNING! The cruise
control should not be used
in heavy traffic or when
driving on wet or slippery
roads. Do not use or
resume cruise control in
reverse gear. When the
ignition is switched off,
any information stored in
the cruise control memory
will be erased.

Cruise control

The cruise control switches are
located on the turn signal switch
lever.
To engage and set desired
speed:
1. Set switch (B) to ON.
2. Accelerate to desired cruise
speed.

NOTE:The cruise control cannot
be engaged at speeds below 22
mph (35 km).

3. Press the + or - area of the SET
button (A) to set the desired
speed. Braking
This will automatically disengage
the cruise control. Previously
selected cruise control speed is
retained in the memory and by
momentarily setting the switch to
RESUME position, that speed will
be re-engaged.

If the cruise control is already
engaged, the cruising speed can be
increased or decreased by
depressing the SET button (A)
towards either + or -. One short
press on the button corresponds to
a speed change of approx. 1 mph
(1.6 km/h). When the button is
released, the vehicle will maintain
the current speed.

If actual speed falls below 70% of
set speed or if the wheels spin or

lock, the cruise control will
disengage automatically.
Heating, ventilation and air conditioning pg. 25


ECC - Electronic Climate Control

This is an automatic system that also permits
manual operation. The in-car temperature is
automatically monitored by two sensors located in
the passenger compartment.
One sensor is located on the top of the dashboard
where it can sense sunlight. The second sensor is
located on the courtesy light fixture where it can
sense the temperature in the center of the car. The
following pages describe how ECC works and
how it can be used most effectively.

Refrigerant

Volvo cares about the environment. The air
conditioning system in your car contains a CFC-
free refrigerant - R134a. This substance will not
deplete the ozone layer. The system contains 2 lbs
(0.9 kg) R134a and uses Sanden SP-20 (type
PAG) oil.

Air vents (dash)

A Open
B Closed
C Directing air flow horizontally
D Directing air flow vertically

NOTE:All maintenance on the climate control
systems should be carried out by an authorized
Volvo service technician only.

*When the function selector is in the
mode, the air conditioning
system is ON and recirculation is OFF, regardless
of button position. The light surrounding the "Snowflake" button will be\

OFF and the light surrounding the recirculation button will be OFF.

NOTE: If your windows begin to fog or mist, check that the
recirculation function is not engaged.
Heating, ventilation and air conditioning (cont.) pg. 27
Automatic setting

The ECC system will automatically
maintain a comfortable in-car
temperature regardless of the outdoor
temperature.


Select the desired temperature

The blower will run at its maximum
speed in either the max cooling or max
Operating Tips

Recirculation: When the
outside air is contaminated
with exhaust gases, smoke
etc. (as when driving
through a tunnel) or to cool
the car quickly, push the
recirculation button. In this
position, no air is drawn into
the passenger compartment
from outside. However, do
not leave the system in this
mode for more than 10-15
minutes, since the air inside
the car will become stale
and the windows may fog.
Recirculation (and the
indicator light) will also
come on when the interior of
the car is hot and a low
temperature is selected with
the temperature dial. This
helps speed cooling of the
passenger compartment. It
will switch off automatically
after several minutes.

Difficult weather
conditions

When driving in very humid ECC system fault
indication

If the light in the air
conditioning push button
begins to flash when the
ignition is switched on, a
simple fault is indicated.
The system will compensate
by substituting a standard
value stored in the memory.
System performance loss
will be slight.
If the light continues to flash
more than 20 seconds, a
more serious fault is
indicated. While the system
will again attempt to
substitute a standard value,
some reduction in system
performance will become
apparent. Contact your
authorized Volvo retailer for
service.

conditions, heavy rain, sleet,
etc., it may be better to use
the manual rather than the
automatic setting to defrost
the windows. Set the mode
selector to "Defrost" or
"Defrost/floor" and the fan
speed to 3 or higher. Also
shut the middle air vents. NOTE:
l Do not place any
objects over the
sensor in the
passenger side
speaker grille as
this will cause the
ECC system to
respond incorrectly
to ambient
conditions.
l To help maintain
stable passenger
compartment
temperature when
driving with the sun
roof or windows
open, place the
blower control in
position "0" and
adjust the desired
temperature
manually.
l The air
conditioning
compressor only
engages at
temperatures above
41°F (5°C).
l Always keep the air

base of the
windshield free of
snow.

Heated front seats
pg. 28


Heated front seats (certain models)

The heated front seats can be switched on and off
as required. When switched on, the system senses
the ambient temperature and regulates the level of
heat applied. When the optimum temperature is
reached, the heating is switched off automatically.
While driving, the passenger seat heating should
be switched off when the seat is not occupied.
Electrically operated windows pg. 29


Electrically-operated windows

The electrically operated windows are controlled
by switches from the driver's armrest as shown in



Cut-out switch for rear-door windows

If the car is equipped with rear door power
windows, this function can be disabled by a
switch located on the driver's armrest. This switch

ON The rear door windows can be raised or
lowered with the respective door switch as well as
the switch on the driver's door.
OFF The rear door windows cannot be raised or
lowered with the respective door switch but
instead only with the corresponding switch on the
driver's door.

NOTE: The power window motors have an
overload protecting circuit breaker which is
activated when an object blocks a window.
Should this occur, remove the object and wait 20
seconds for the circuit breaker to reset. The power
windows should then function.
