General information

Shiftlock
When your car is parked, the gear selector is locked in the (P)ark pos\
ition. To release the selector from
this position, turn the ignition key to position II (or start the engin\
e), depress the brake pedal, press the
button on the front of the gear selector knob and move the selector from\
(P)ark.
Keylock
This means that when you switch off the ignition, the gear selector must\
be in the (P)ark position before
the 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 vehi\
cle first reaches the speed of
approximately 12 mph (20 km/h). The brake pedal will pulsate several t\
imes and a sound may be audible
from the ABS control module. This is normal.
Fuel filler door
Press the button on the light switch panel (see
page 34) when the car is at a standstill to unlock the fuel
filler door. Please note that the fuel filler door will remain unlocked \
until the car begins to move
forward. An audible click will be heard when the fuel filler door relock\
s.
Fuel filler cap
After refueling, close the fuel filler cap by turning it clockwise until\
it clicks into place. If this cap is not
closed tightly or if the engine is running when the car is refueled, the\

l When cleaning your car, use Volvo's own car care products, all of which \
have systematically been
adapted to the environment
PremAir®
On the surface of the radiator in the engine compartment, there is a spe\
cial coating called PremAir®.
PremAir® works as a catalytic converter, converting most of the ozone\
passing through the radiator into
oxygen, thereby reducing harmful ground-level ozone.

Chapter 1 - Safety


pg. 1 Safety

Not wearing a seat belt is like believing "It'll never happen to me!" Vo\
lvo, the inventor of the three-point
seat belt, urges you and all adult occupants of your car to wear seat be\
lts and ensure that children are
properly restrained, using an infant, car or booster seat determined by \
age, weight and height. Volvo also
believes no child should sit in the front seat of a car.
Fact: In every state and province, some type of child-restraint legislation h\
as been passed. Additionally,
most states and provinces have already made it mandatory for occupants o\
f a car to use seat belts.
So, urging you to "buckle up" is not just our recommendation - legislati\
on in your state or province may
mandate seat belt usage. The few seconds it takes to buckle up may one d\
ay allow you to say, "It's a
good thing I was wearing my seat belt."

l Have the car towed to an authorized Volvo retailer. Never drive with the\
airbags deployed.
l Have an authorized Volvo retailer replace the SRS system components.
l Use only new, Genuine Volvo Parts when replacing SRS components (airbag\
s, seat belts, tensioners,
etc.).
When are the airbags NOT deployed?
Not all frontal collisions activate the SRS system. If the collision inv\
olves a nonrigid object (e.g., a snow
drift or bush), or a rigid, fixed object at a low speed, the SRS system\
will not necessarily deploy. Front
airbags do not normally deploy in a side impact collision, in a collisio\
n from the rear or in a rollover
situation. The amount of damage to the bodywork does not reliably indica\
te if the airbags should have
deployed or not.
Seat belts - the heart of the Volvo safety system
The heart of the Volvo safety system is the three-point seat belt (a Volvo invention)! In order for the
SRS system to provide the protection intended, seat belts must be worn a\
t all times by everyone in the
car. The SRS system is a supplement to the seat belts.
WARNING!
If your car has been subjected to flood conditions (e.g. soaked carpeti\
ng/standing water on the floor
of the vehicle) or if your car has become flood-damaged in any way, do \
not attempt to start the
vehicle or put the key in the ignition before disconnecting the battery \
(see below). This may cause
airbag deployment which could result in personal injury. Have the car to\
wed to an authorized Volvo
retailer for repairs.
Automatic transmission:
Before attempting to tow the car, use the following procedure to overrid\
e the shiftlock system to
move the gear selector to the neutral position.
l Switch off the ignition for at least 10 minutes and disconnect the batte\
ry
l Wait at least one minute
l Insert the key in the ignition and turn it to position II
l Press firmly on the brake pedal.
l Move the gear selector from (P)ark to the (N)eutral position.

pg. 18 Brake system

Brake circuit malfunction
The brake system is a hydraulic system consisting of two master cylinder\
s and two separate brake
circuits. If a problem should occur in one of these circuits, it is stil\
l possible to stop the car with the other
brake circuit.
If the brake pedal must be depressed farther than normal and requires gr\
eater foot pressure, the stopping
distance will be longer.
A warning light in the instrument panel will light up to warn the driver\
that a fault has occurred.
If this light comes on while driving or braking, stop immediately and ch\
eck the brake fluid level in the
reservoir.
NOTE: Press the brake pedal hard and maintain pressure on the pedal - do not pump the brakes.
WARNING!
If the fluid level is below the MIN mark in the reservoir: DO NOT DRIVE.\
Tow the car to a Volvo
retailer and have the brake system inspected.
NOTE: When the car is at a standstill and the engine is idling, e.g. at a traf\
fic light and the brake pedal
is depressed, the pedal may go down slightly. This is normal and is caus\
ed by an built-in function in the
power brake system.

2004 VOLVO XC70
Power brakes function only when the engine is running
The power brakes utilize vacuum pressure which is only created when the \
engine is running. Never let
the vehicle roll to a stop with the engine switched off.
If the power brakes are not working, the brake pedal must be pressed app\
roximately four times harder
than usual to make up for the lack of power assistance. This can happen \
for example when towing your
vehicle or if the engine is switched off when the vehicle is rolling. Th\
e brake pedal feels harder than
usual.
Water on brake discs and brake pads affects braking
Driving in rain and slush or passing through an automatic car wash can c\
ause 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 brake \
application feels normal. This
should also be done after washing or starting in very damp or cold weath\
er.
Severe strain on the brake system
The brakes will be subject to severe strain when driving in mountains or\
hilly areas or towing. Vehicle
speed is usually slower, which means that the cooling of the brakes is l\
ess efficient than when driving on
level roads. To reduce the strain on the brakes, shift into a lower gear\
and let the engine help with the
braking. Do not forget that, if you are towing a trailer, the brakes wil\
l be subjected to a greater than
normal load.
pg. 19 Anti-lock Brake System (ABS)


Anti-lock Brake System (ABS)
If the warning lamp lights up there is a malfunction of the ABS system (\
the standard braking system will
however function) and the vehicle should be driven cautiously to a Volv\
o retailer for inspection. The
Anti-lock Braking System (ABS) helps to improve vehicle control (stop\
ping and steering) during severe
braking conditions by limiting brake lockup. When the system "senses" im\
pending lockup, braking
pressure is automatically modulated in order to help prevent lockup, whi\
ch could lead to a skid.
The system performs a self-diagnostic test when the engine is started an\
d when the vehicle first
reaches a speed of approximately 12 mph (20 km/h). The brake pedal will pulsate several times and a
sound may be audible from the ABS control module. This is normal.

2004 VOLVO XC70
To obtain optimal effect from the ABS system, constant pressure should b\
e kept on the brake
pedal, keep constant pressure on the brake pedal. Do not pump the brake \
pedal.
The switching of the ABS modulator will be audible and the brake pedal w\
ill pulsate during braking.
Please be aware that ABS does not increase the absolute braking potentia\
l of the vehicle. While control
will be enhanced, ABS will not shorten stopping distances on slippery su\
rfaces.
ABS with EBD (Electronic Brake Force Distribution)
EBD is an integrated part of the ABS system. EBD regulates the hydraulic\
pressure to the rear brakes to
help provide optimal braking capacity. The brake pedal will pulsate duri\
ng braking, which is normal.
If the BRAKE and ABS warning lights come on at the same time, this could\
indicate a fault in the
brake system.
l Stop the car in a suitable place and switch off the engine.
l Restart the engine.
l If both warning lights go off, no further action is required.
l If both lights are still on after the engine has been restarted, switch \
off the engine again and check the
brake fluid level (see
pages 139 and for the location of the brake fluid reservoir).
WARNING!
If the fluid level is below the MIN mark in the reservoir, DO NOT DRIVE.\
Have the car towed to an
authorized Volvo retailer and have the brake system inspected.

l If the brake fluid level is above the MIN mark, drive carefully to an au\
thorized Volvo retailer and
have the brake system inspected.

06 4:32:55 PM

2004 VOLVO XC70
The stability systems consist of a number of functions:
The following two functions are common to both STC/DSTC
1. Traction control (TC)
This function is designed to help reduce wheel spin by transferring powe\
r from a drive wheel that begins
to lose traction to the wheel on the opposite side of the car (on the s\
ame axle). TC monitors and
compares the rotational speed of the drive wheels. If one of the drive w\
heels shows a tendency to spin,
the difference in speed is immediately detected. This triggers the Anti-\
lock Brake System, which brakes
the spinning wheel until the difference in rotational speed is corrected\
.
TC is most active at low speeds, and a pulsating sound will be audible w\
hen the system is regulating
wheel spin. This is quite normal.
This is one of the STC/DSTC's permanent functions and is not affected wh\
en the button on the center
control panel is pressed.
2. Spin control (SC)
The spin control function is designed to help prevent the drive wheels f\
rom spinning while the car is
accelerating. This is done by temporarily reducing engine torque to the \
drive wheels, which helps
improve stability and tractive force.
Under certain circumstances, such as when driving with snow chains, or d\
riving in deep snow or loose
sand, it may be advisable to temporarily switch off this function for ma\
ximum tractive force. This is
done by pressing the STC/DSTC button on the center control panel for at \
least a half a second.
When the SC function has been switched off:
l The text window (see page 27) will briefly display "SPIN CONTROL OFF"
l The LED in the STC/DSTC button will be off.
The following two functions are only available with DSTC:
3. Active Yaw Control (AYC)
This function helps maintain directional stability, for example when cor\
nering, by braking one or more
of the wheels if the car shows a tendency to skid or slide laterally. Th\
is is done by activating the Anti-
lock Braking System. A pulsating sound will be audible when the function\
is active, which is quite
normal. If you apply the brakes while this function is active, the brake\
pedal will feel stiffer than usual.
This is also one of the DSTC system's permanent functions and is not aff\
ected when the DSTC button on
the center control panel is pressed.
R-models only:
The AYC function can be deactivated. This is done by pressing the DSTC b\
utton on the center control
panel (see the illustration on
page 31) for approximately one second. This procedure must be repeated 5
times, after which "DSTC REDUCED FUNCTION" will be displayed in the text\
window. AYC will be

automatically reactivated the next time the ignition is switched on. WARNING!
With AYC disabled, the car's handling and stability characteristics will\
be altered.
4. Emergency Brake Assistance (EBA)
The EBA function is an integrated part of the DSTC system. EBA is design\
ed to provide full brake
effect immediately in the event of sudden, hard braking. The system is a\
ctivated by the speed with which
you depress the brake pedal.
When the EBA system is activated, the brake pedal will go down and press\
ure in the brake system
immediately increases to the maximum level.
pg. 21 STC/DSTC
Maintain full pressure on the brake pedal in order to utilize the system\
completely. EBA is automatically
deactivated when the brake pedal is released. When the car has been park\
ed for some time, the brake
pedal may sink more than usual when the engine is started. This is norma\
l and the pedal will return to its
usual position when it is released.
The STC/DSTC button
The STC/DSTC button in the center control panel (see page 31) is used to switch the Spin Control (SC)
function on or off
NOTE: AYC (on models equipped with this function) will also be reduced, but\
not switched off, if SC
is switched off.
The button must be pressed for at least a half second to prevent SC from\
being switched off
inadvertently.
When the function has been switched off, the green indicator lamp in the\
button will go out and "STC/
DSTC SPIN CONTROL OFF" will be displayed in the text window.
All STC/DSTC functions are (re)activated each time the engine is start\
ed.
The Stability Control indicator light

2004 VOLVO XC70
The Stability Control indicator light will come on for approximately 2 s\
econds when the ignition is
switched on as the system performs a self-diagnostic test.
The Stability Control indicator light will flash when:
l Traction Control is actively functioning to help avoid drive-wheel spin.\

l Spin Control is actively functioning to help avoid loss of traction duri\
ng acceleration.
l Active Yaw Control is actively functioning to help avoid skids or latera\
l slides.
The warning symbol in the instrument panel
A steady yellow glow indicates:
l That the system has been automatically disengaged due to a fault. "ANTI \
SKID SERVICE
REQUIRED" be displayed in the text window. An authorized Volvo retailer \
should check the system.
l The system has been temporarily switched off due to high brake temperatu\
re. "TRACTION
CONTROL TEMPORARILY OFF" will be displayed.
NOTE: The system will automatically switch on again when the brakes have cool\
ed.
