possible.
Starting the engine pg. 57
Starting and stopping a
car equipped with
automatic transmission
1 Fasten the seat belt.
WARNING! Before
starting, check that the seat
is adjusted properly. Make
sure the brake pedal can be
depressed completely. Move
the seat closer if necessary.
Refer to section "Front
seats".
2 Apply the parking brake, if
not already set. The gear
selector is locked in the (P)ark
position (SHIFTLOCK).
3Without touching the
accelerator pedal ,turn the
ignition key to the starting
position. Allow the starter to
operate for 5-10 seconds.
Release the key as soon as the
engine starts. If the engine fails
to start, repeat step 3.
5 Select desired gear. The gear
engages after a slight delay,
especially noticeable when
selecting R.
CAUTION: Engine should
be idling; never accelerate
until after you feel the gear
engage! Too rapid
acceleration immediately
after selecting a gear will
cause harsh engagement and
premature transmission
wear.
NOTE:Your car is equipped
with a KEYLOCK system.
When the engine is switched
off, the gear selector must be in
the (P)ark position before the
key can be removed from the
ignition switch.
Engine warm-up - initial
driving procedure
Engines in vehicles driven short
distances are subject to
abnormally rapid wear because
the engine never reaches normal
operating temperature. It is
therefore beneficial to reach
normal operating temperature as
soon as possible. This is best
achieved by driving with a light
foot on the accelerator pedal for
a few minutes after starting,
rather than prolonged idling.
B6304 S Engine
This engine features hydraulic
valve lifters which means that
valve clearance is adjusted
automatically. It is possible that
the valve lifters will produce a
ticking sound for the first few
seconds after the engine is
started, while the oil pressure is
increasing.
If the car has not been used for a
long period of time, this ticking
sound may last for up to 15
minutes. This is entirely normal.

driving modes E or S. There
is no upshift from third gear.
Position 3 can be used for
driving in hilly terrain, for
towing trailers or for
increased engine braking
power.
CAUTION: Never select P
or R while the car is in
motion. 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. The gear
selector should not be
downshifted to L at speeds
above 75 mph (125 km/h). -
Always observe posted
speed limits!

Kick-down
Automatic shift to a lower gear
(kick-down) is achieved by
depressing the accelerator pedal
fully and briskly.
An up-shift will be achieved
when approaching the top speed
for a particular gear or by
releasing the accelerator pedal
slightly. Kick-down can be used
for maximum acceleration or
when passing at highway
speeds.
The indicator lamp in the
instrument panel lights up when
mode W is selected. Press button
W in order to disengage this
mode.
When mode W is disengaged,
the gearbox automatically
reverts to the previously selected
S or E mode.
If the indicator lamp begins to
flash, this is an indication of a
fault in the automatic gearbox. If
the transmission does not shift
properly, place the gear selector
in position L. Please contact
your Volvo retailer if this
occurs.

The pedal stroke increases
slightly, the pedal feels softer
and extra pressure is required for
normal braking.
If the light comes on while
driving or braking, stop
immediately and check the brake
fluid level in the reservoir.
WARNING!
If the fluid level is below the
MIN mark in either section
of the reservoir: DO NOT
DRIVE. Tow the car to a
Volvo retailer and have the
brake system checked and
repaired.
Anti-lock Brake System

ABS system (the standard
braking system will however
The system performs a self-
diagnostic test when the vehicle
is started and at 4 mph (6 km/h).
The driver may detect one
pulsation of the brake pedal,
which is normal.
To obtain optimal effect from
the ABS system, constant
pressure should be kept on the
brake pedal while the system
is modulating the brakes. Do
not pump the brake pedal.
The switching of the ABS
modulator will be audible at this
time.
Please be aware that ABS does
not increase the absolute braking
potential of the vehicle.
While control will be enhanced,
ABS will not shorten stopping
distances on slippery surfaces.
Moisture on brake
discs and brake pads
affects braking.
Driving in rain and slush or
passing through an automatic car
wash can cause water to collect
on the brake discs and pads.
This will cause a delay in
braking effect when the pedal is
depressed. To avoid such a delay
when the brakes are needed,
depress the pedal occasionally
when driving through rain, slush
etc. This will remove the water
from the brakes. Check that
Severe strain on the
brake system
The brakes will be subject to
severe strain when driving in
mountains or hilly areas or
towing. The speed is usually low
which means that the cooling of
the brakes is less efficient than
when driving on level roads. To
reduce the strain on the brakes it
is advisable not to use the brakes
excessively. Instead, shift into a
lower gear, position 3 or in some
cases L ,and let the engine help
with the braking.
Do not forget that, if you are
towing a trailer, the brakes will
be subjected to greater load than
is normal.
If the brake power-
assist does not
function
The power assist to the brakes
functions only when the engine
is running. When the car is
moving without the engine
running the brake pedal pressure
required to stop the car is
increased by 3-4 times.
The brake pedal feels stiff and
hard.

function) and the vehicle should
be driven to a Volvo retailer for
inspection.
The Anti-lock Braking System
(ABS) helps to improve vehicle
control (stopping and steering)
during severe braking conditions
by limiting brake lock-up. When
the system "senses" impending
lock-up, braking pressure is
automatically modulated in
order to help prevent lockup,
which could lead to a skid. brake application feels normal.
This should also be done after
washing or starting in very damp
or cold weather.
Trailer towing pg. 68
When preparing for
trailer towing, observe
the following:
l Volvo recommends the use of
Volvo trailer hitches which are
specially designed for the car.
For trailer weights exceeding
2000 lbs. (908 kg), use only a
trailer hitch offered as a
Genuine Volvo accessory.
NOTE: Models with automatic
transmission are equipped with
a transmission oil cooler as
standard equipment. This cooler
helps prevent overheating of the
transmission during times of
increased load, as when towing
a trailer.
l Maximum trailer weight
recommended by Volvo is:
Trailers without brakes: 1100
lbs (500kg)
Trailers with brakes: 2" ball -
3300 lbs (1500 kg), 1 7/8" ball -
2000 lbs (908 kg).
WARNING! Never connect a
trailer's hydraulic brake
system directly to the vehicle
brake system, nor a trailer's
lighting system directly to the
vehicle lighting system.
Consult your nearest
authorized Volvo retailer for
correct installation.
All Volvo models are equipped
with energy-absorbing shock-
mounted bumpers. Trailer hitch
installation should not interfere
with the proper operation of this
bumper system. Trailer towing
does not normally present any
particular problems, but take
into consideration:
l Recommended hitch tongue
load is 110 lbs (50 kgs) for
trailer weights below 2,650 lbs
(1,200 kgs) and 165 lbs (75 kgs)
for trailer weights above 2,650
lbs (1,200 kgs).
l For trailer weights between
2,650-3,300 lbs (1,200-1,500
l Avoid overload and other
abusive operation.
l Hauling a trailer affects
handling, durability, and
economy.
l It is necessary to balance
trailer brakes with the towing
vehicle brakes to provide a safe
stop (check and observe State/
Local regulations).
l Do not connect the trailer's
brake system directly to the
vehicle's brake system.
l More frequent vehicle
maintenance is required.
l Remove the ball and drawbar
assembly when the hitch is not
being used.
l Volvo recommends the use of
synthetic engine oil when towing
a trailer over long distances or in
mountainous areas.
l The trailer hitch tongue load
(110/165 lbs - 50/75 kg) is part
of the vehicle's capacity weight.
It may be necessary to reduce the
trunk/cargo area load when

cold-weather oil for hard driving or in warm
weather. See section "Engine oil" for more
information.
l The load placed on the battery is greater during
the winter since the heater, windshield wipers,
lighting etc. are used more often. Moreover, the
capacity of the battery decreases as the
temperature drops. In very cold weather, a poorly
charged battery can freeze and be damaged. It is
therefore advisable to check the state of charge
more frequently and spray an anti-rust oil on the
battery posts.
l Volvo recommends the use of snow tires on all
four wheels for winter driving - see section
"Wheels and tires".
l To prevent the washer reservoir from freezing,
add washer solvents containing antifreeze. This is
important since dirt is often splashed on the
windshield during winter driving, thus requiring
frequent use of the washers and wipers.

Long distance trip pg. 70
Before a long distance trip
It is always worthwhile to have your car checked at a Volvo retailer
before driving long distances. Your retailer will also be able to supply\
you with bulbs, fuses, spark plugs and wiper blades for your use in the \
event that problems occur.
If you prefer to check the car yourself, please note the following:
l Check that the engine runs smoothly and that fuel consumption is
normal.
l Check engine oil, coolant levels, and for possible fuel leakage.
l Check transmission oil level and rear axle for leakage.
l Check condition of drive belts.
l Check state of charge of battery.
l Examine tires carefully (the spare tire as well), and replace those
that are worn. Check tire pressures.
l The brakes, front wheel alignment, and steering gear should be
checked by your Volvo retailer only.
l Check all lights, including high beams.

When replacing tires, be sure that the new tires
are the same size designation, type (radial) and
preferably from the same manufacturer, on all
four wheels. Otherwise there is a risk of altering
the car's road-holding and handling
characteristics.
NOTE:When storing wheel/tire assemblies (e.g.
winter tires and wheels), either stand the
assemblies upright or suspend them off the
ground. Laying wheel/tire assemblies on their
sides for prolonged periods can cause wheel and/
or tire damage.
Wear indicator
The tires have a so-called "wear indicator" in the
form of a number of narrow strips running across
or parallel to the tread. When approx. 1/16" (1.6
mm) is left on the tread, these strips show up and
indicate that the tire should be replaced.
Tires with less than 1/16" (1.6 mm) tread have a
very poor grip in rain or snow.
All tires become warm during use. After cooling,
when the vehicle is parked, the tires have a
tendency to distort slightly, forming flat spots.
These flat spots can cause vibrations similar to the
vibrations caused by imbalanced wheels.
They do, however, disappear when the tire warms
up. The degree to which the flat spots form
depends on the type of cord used in the tire.
Remember that, in cold weather, it takes longer
for the tire to warm up and consequently longer
for the flat spot to disappear.
Wheels and tires (cont.) pg. 73
Snow chains
Snow tire chains can be used on your Volvo with
the following restrictions:
l Snow chains should be installed on rear wheels
only. Use only Volvo approved snow chains.
l Snow chains can only be used on tires which
are not wider than 195 mm.
l Sufficient clearances between chains and
brakes, suspension and body components must be
maintained.
l Some strap-on type chains will interfere with
brake components and therefore CANNOT be
used.
Consult your Volvo retailer for additional snow
Snow tires, studded tires*
Tires for winter use:
Owners who live in or regularly commute
through areas with sustained periods of snow
or icy driving conditions are strongly advised
to fit suitable winter tires to help retain the
highest degree of traction.
It is important to install winter tires on all four
wheels to help retain traction during cornering,
braking and accelerating. Failure to do so could
reduce traction to an unsafe level or adversely
affect handling. Do not mix tires of different
design as this could also negatively affect overall
tire road grip.
