Headlights and parking lights

All lights off *

Parking lights on **

Headlights and parking lights are on if
starting (ignition) switch is in position I or II. If
the headlight switch is in position
all lights
will go out when starting switch is switched off.
With the headlight switch in position
the
parking lights will stay on (headlights off) with
the daytime running light switch (A) in position
.
The high beams can only be switched on if the
headlight switch is in position
.
Switch from high to low beams, and vice versa,
by moving the turn signal switch lever on the left
side of the steering column towards the steering
wheel.
*Models equipped with daytime running lights:
The low beams, tail lights, parking lights and
license plate lights will come on automatically
when the ignition is switched on.
Automatic daytime running lights
NOTE: The daytime running light function may
only be disabled (turned off) in the U.S. -
Canadian law mandates the use of daytime
running lights.
Screw A in the illustration (available on U.S.
models only) is used to control the automatic
daytime running lights when the headlight switch
is in position 0. To adjust, press in the screw with
a small screwdriver and turn to one of the
following positions:

obtained by depressing the
selector knob prior to moving
the selector.
Slightly depressing the selector
knob allows selection of
positions N, D, 3 and L. Fully
depressing the selector knob
allows selection of positions R
and P. This is also necessary
when initially bringing the
selector out of position P. Fully
depressing the selector knob
thus permits shifting freely
between all positions.Mode selector

The push-buttons to the left of
the gear lever are for selection of
modes E, S and W. Any mode
can be selected while the car is
on the move.

Winter/Wet mode
Enhanced Vehicle Traction
This mode may be selected for
starting/moving off on slippery
roads or to lower downshift
speeds if the transmission is in
"L".
In this mode:
l In position D*, the gearbox
starts in third gear and changes
up to fourth gear.
l In position 3*, second gear is
locked and there is no change up
to third gear.
l In position L, first gear is
locked.
*These positions always offer
the kick-down feature.
CAUTION: Driveability and
fuel economy will be
adversely affected by
prolonged driving in mode W .
Volvo recommends using this
mode only when starting in
extremely slippery conditions.

Sport Mode
This mode is adapted to "sporty"
driving characteristics. The
transmission upshifts at higher
engine speeds and less
accelerator pedal pressure is
required to initiate a downshift.

Economy Mode
This mode is used normally. The
gearbox changes gears at a
lower engine speed to achieve
the best possible fuel
consumption.

"Lock-up"
The automatic gearbox has a
"lock-up" function. It reduces
engine speed and saves fuel. The
"lock-up" function can
sometimes be felt as an
additional gear change.

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.

Replacing wiper
blades


Lift the wiper arm off
the windshield and hold
blade at right angles to
arm. Pinch the end of
the plastic clip located
at the back of the arm.

Slide the wiper blade
along the arm to release
it from the hook.

Install new blade
(installation is the
reverse of removal) and
make sure that it is
properly attached to the
wiper arm.

For reasons of safety,
you should change the
windshield wiper blades
as soon as they start to
leave marks on the
windshield or fail to
wipe efficiently and
cleanly.

To obtain maximum
lifetime from a set of
wiper blades, clean
them with a stiff-bristle
brush and warm, soapy
water as part of a
normal car wash.


Replacing headlight
wiper blades (certain
models)


Pull the wiper blade in the
direction indicated by the arrow
in the illustration to remove it.
Press the new blade into place.
Check that the new blade is
properly attached to the wiper
arm.

Chapter 8 - (cont.)Engine oil
pg. 108
Checking the oil level

The oil level should be checked every
time the car is refuelled. This is
especially important during the engine
break-in period (up to the first service).

CAUTION: Not checking the oil level
regularly can result in serious engine
damage if the oil becomes too low.


Be sure the oil level is maintained between
the upper and lower marks on the dipstick.
Low oil level can cause internal damage to
the engine and over-filling can result in
high oil consumption. The distance
between the dipstick marks represents
approx. 1 US qt (1 liter) of oil. Before
checking the oil level after the car has been
driven, park the car on a level surface and
wait at least 5 minutes after the engine has
been switched off. The oil level should be
halfway between the MIN and MAX
marks.
If the oil is checked before the car is driven
(engine completely cold) the oil level
should be at the MAX mark.

NOTE: The engine must be stopped when
checking the oil.

Draining the oil

Drain the oil after driving while it is still
warm.

WARNING! The oil may be very
hot.
To add or change engine oil

Add oil of the same kind as already used.
Capacity (including filter): 5.9 US qts = 5.75 liters

Changing oil filter



Replace the oil filter at every oil change



WARNING! Oil spilled on a hot exhaust pipe
constitutes a fire risk.

SFI is all-electronic and microprocessor-
controlled. It can continually compensate for
variations in engine load, speed and temperature
to give the best economy and power. An
important feature of the system is a mass air flow
sensor that measures the mass of the inducted air
instead of the volume. In this way the system can
make instantaneous adjustments for changes in air
temperature or density, thus always assuring the
best economy with the lowest possible exhaust
emissions.

Heated oxygen sensor

This is an emission control system designed to
reduce emissions and improve fuel economy. The
heated oxygen sensors monitor the composition of
the exhaust gases leaving the engine. The exhaust
gas analysis is fed into an electronic module. This
adjusts the air-fuel ratio to provide optimum
conditions for combustion and efficient reduction
of the three major pollutants (hydrocarbons,
carbon monoxide and oxides of nitrogen) by a
three-way catalytic converter.
Air pump system

During cold starts, an electric pump is activated
which directs air to the exhaust channels. This
initiates a secondary combustion of exhaust gases
which helps minimize hydrocarbon and carbon
monoxide levels and reduces warm-up time for
the three-way catalytic converter. The pump
begins to function when the engine is started. It
remains in operation until the three-way catalytic
converter has reached normal operating
temperature. A sound may be audible from the air
pump during this warm-up period. This is normal.
When idling, the air pump performs a self-
diagnosis. A soft whining noise can be heard,
which is also normal.
Emissions systems pg. 113


Evaporative control system (EVAP)

The engine is equipped with a fuel evaporation
system which prevents the emission of fuel vapor
