1998 Volvo S90
This means that when you switch off the ignition,
the gear selector must be in the (P)ark position
before the starting (ignition) key can be removed
from the ignition switch.
Anti-Lock Brake System (ABS)
The ABS system in your car performs a self-
diagnostic test when the vehicle is started and at
4 mph (6km/h). The driver may detect one
pulsation of the brake pedal and a sound will be
audible from the ABS control module. This is
normal.
The pages in this section provide detailed
descriptions of the vehicle's instruments and
controls.
Note that vehicles may be equipped differently,
depending on special legal requirements. 16 Controls for electrically operated windows...

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.

Special Tips - automatic transmission
l For driving down steep hills and when driving
for prolonged periods at low speeds, position L
should be selected. Avoid, however, repeated
changes since this can cause overheating of the
transmission oil. For driving on long continuous
uphill gradients, select position 3.
l Do not hold the car stationary on an incline by
using the accelerator pedal. Instead, apply the
hand brake (parking brake). This prevents the
transmission oil from becoming overheated.
l When towing a trailer, select shift position 3.
l The (E)conomy mode should be selected when
the cruise control is engaged.
l Never select P or R while the car is in motion.
l When initially selecting positions D, 3, L or R,
your right foot should press firmly on the brake
pedal to ensure that the car is standing still with
the engine idling.
l The gear selector should not be downshifted to
L at speeds above 75 mph (125 km/h). Always
observe posted speed limits. Cooling system
The risk for overheating is greatest, especially in
hot weather, when:
l towing a trailer up steep inclines for prolonged
periods at wide open throttle and low engine rpm.
l stopping the engine suddenly after high speed
driving (so-called "after-boiling" can occur).
To avoid overheating, the following rules should
be followed:
l Reduce speed and downshift when towing a
trailer up long, steep inclines. The risk of
overheating can be reduced by switching off the
air conditioning system for a short time.
l Do not let the engine idle unnecessarily for
prolonged periods.
l Do not mount auxiliary lamps in front of the
grill.
When the risk of overheating is imminent, or in
the event of overheating, (the temperature gauge
goes repeatedly into, or stays continually in, the
red section) the following precautions should be
taken:
l Switch off the air conditioning system.
l Pull off the road, away from traffic, stop the car
and put the gear lever into neutral. Do not stop the
engine!
l Switch the heater to full (maximum) position.
Increase the engine speed to approx. 2000 rpm
(twice idling speed) until the temperature begins
to drop.
See "Coolant" to check and top-up the coolant
level if necessary.
WARNING! Do not remove coolant expansion
tank cap. The coolant will be extremely hot.
