he hood and check the brake
fluid level in the reservoir. See
page 126 for reservoir position and page 130 for instructions.
Canadian models are equipped with this warning light.
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 vehicle 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

DSTC
The Dynamic Stability and Traction Control system (DSTC) is explained \
in greater detail on
pages 95
and 96. This system consists of several functions:
Risk for slippery conditions
If the warning light comes on and stays on, this indicates that traction\
with the road surface is reduced.
Drive with caution.
If this light flashes, it indicates that the DSTC system is working to restore traction to on\
e or more of the
wheels.
Reduced Stability Control
If the green indicator light in the DSTC button goes out, DSTC has reduc\
ed effect because the system
had been switched off with the button in the center console. The text DS\
TC SPIN CONTROL OFF will
be displayed in the text window.
Reduced anti-spin function
If the yellow indicator light comes on and remains on, DSTC's Stability \
Control function has been
switched off due to excessively high brake temperature. The text TRACTIO\
N CONTROL
TEMPORARILY OFF will be displayed in the text window.

starter to operate for up to 10 seconds. Release the key as soon as the \
engine starts. If the engine fails to
start, repeat this step.
NOTE:
- On certain models, when the vehicle is started, idle speed may be noti\
ceably higher than normal for a
short period, depending on the temperature of the engine.
This has been done to help bring components in the emission control syst\
em to their normal operating
temperature as quickly as possible, which enables them to function norma\
lly.
- For cold starts at altitudes above 6000 ft (1800 meters), depress th\
e accelerator pedal halfway and turn
the key to the starting position. Release the pedal slowly when the engi\
ne starts.
4. To release the gear selector from the (P)ark position, the engine must be running (or the ignition key
must be in position II) and the brake pedal must be depressed.
5. Select the desired gear. The gear engages after a very slight delay w\
hich is especially noticeable when
selecting R.
NOTE: Your vehicle is equipped with a Keylock system. When the engine is switc\
hed off, the gear
selector must be in the (P)ark position before the key can be removed \
from the ignition switch.
When starting in cold weather, the transmission may shift up at slightly\
higher engine speeds than
normal until the automatic transmission fluid reaches normal operating t\
emperature.
Do not race a cold engine immediately after starting. Oil flow may not r\
each some lubrication points fast
enough to prevent engine damage.
* If two of the keys to your vehicle are close together, e.g., on the sa\
me key ring, when you try to start
the vehicle, this could cause interference in the immobilizer system and\
result in the vehicle not starting.
If this should occur, remove one of the keys from the key ring before tr\
ying to start the vehicle again. CAUTION
Automatic transmission
The engine should be idling when you move the gear selector. Never accel\
erate until after you feel
the transmission engage! Accelerating immediately after selecting a gear\
will cause harsh engagement
and premature transmission wear.
Selecting P or N when idling at a standstill for prolonged periods of time will help pre\
vent
overheating of the automatic transmission fluid.

Brake system
BRAKE 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 vehicle 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 p\
ump the brakes.
WARNING!
If the fluid level is below the MIN mark in the reservoir or if a "Brake\
failure - Service urgent"
message is displayed in the text window: DO NOT DRIVE. Have the vehicle \
towed to a Volvo
retailer and have the brake system inspected.
NOTE: When the vehicle is at a standstill and the engine is idling, e.g. at a \
traffic light and the brake
pedal is depressed, the pedal may go down slightly. This is a normal fun\
ction of the power-assisted
brake system.
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

Dynamic Stability Traction Control (DSTC)
The DSTC system on the Volvo XC90 consists of a number of functions:
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 vehicle (on t\
he same 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 DSTC system's permanent functions and is not affected\
when the DSTC 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 vehicle is
accelerating. This is done by temporarily reducing engine torque to the \
drive wheels, which helps

WARNING!
- Do not connect the jumper cable to any part of the fuel system or to a\
ny moving parts. Avoid
touching hot manifolds.
Never expose the battery to open flame or electric spark.
- Do not smoke near the battery.
- Batteries generate hydrogen gas, which is flammable and explosive.
- Battery fluid contains sulphuric acid. Do not allow battery fluid to c\
ontact eyes, skin, fabrics or
painted surfaces. If contact occurs, flush the affected area immediately\
with water. Obtain medical
help immediately if eyes are affected.
- Failure to follow the instructions for jump starting can lead to perso\
nal injury.
pg. 101 Starting and driving
Towing a trailer
Volvo recommends the use of Volvo trailer hitches that are specially des\
igned for the vehicle.
l Maximum trailer weights recommended by Volvo are:
All models - trailers without brakes: 1,650 lbs (750 kg)
Models with all wheel drive - trailers with brakes: 4,960 lbs (2250 kg)\

Models with front wheel drive - trailers with brakes: 3,970 lbs (1800 k\
g)
Observe the legal requirements of the state/province in which the vehicl\
es are registered.
l All Volvo models are equipped with energy-absorbing shock-mounted bumper\
s. Trailer hitch
installation should not interfere with the proper operation of this bump\
er system.
Trailer towing does not normally present any particular problems, but ta\
ke into consideration:
l Increase tire pressure to recommended full. See section "Wheels and tire\
s."
l When your vehicle is new, avoid towing heavy trailers during the first 6\
20 miles (1,000 km).
l Recommended hitch tongue load is: Trailer weights below 2,650 lbs (1,200 kg) - 110 lbs (50 kg)
Trailer weights above 2,650 lbs (1,200 kg) - 198 lbs (90 kg)
l Maximum speed when towing a trailer: 50 mph (80 km/h).
l Engine and transmission are subject to increased loads. Therefore, engin\
e coolant temperature should
be closely watched when driving in hot climates or hilly terrain. Use a \
lower gear and turn off the air
conditioner if the temperature gauge needle enters the red range.
l If the automatic transmission begins to overheat, a message will be disp\
layed in the text window.
l Avoid overload and other abusive operation.

state of charge more frequently and spray an antirust 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 fluid reservoir from freezing, add washer solvents containing antifreeze (see
page 126 for the location of the washer fluid reservoir).
This is important since dirt is often splashed on the windshield during \
winter driving, requiring the
frequent use of the washers and wipers. Volvo Washer Solvent should be d\
iluted as follows:
Down to 14° F (-10° C): 1 part washer solvent and 4 parts water \
Down to 5° F (-15° C): 1 part washer solvent and 3 parts water
Down to 0° F (-18° C): 1 part washer solvent and 2 parts water
Down to -18° F (-28° C): 1 part washer solvent and 1 part water \
l Use Volvo Teflon Lock Spray in the locks.
NOTE: Avoid the use of de-icing sprays as they can cause damage to the locks.
W Winter/Wet driving mode-enhanced vehicle traction
l Mode W will only function if the gear selector is in the (D)rive position.
l Press the button at the base of the gear selector to engage/disengage th\
is driving mode.
l An LED in the button will light up to indicate that W is engaged and thi\
s will also be displayed in the
instrument panel (see
page 24).
l This mode may be selected for starting/moving off on slippery roads.
* Synthetic oil is not used when the oil is changed at the normal mainte\
nance intervals except at owner
request and at additional charge. Please consult your Volvo retailer.
pg. 106 Starting and driving
Before a long distance trip
It is always worthwhile to have your vehicle checked at a Volvo retailer\
before driving long distances.
Your retailer will also be able to supply you with bulbs, fuses, spark p\
lugs and wiper blades for your use
in the event that problems occur.
As a minimum, the following items should be checked before any long trip\
:
l Check that engine runs smoothly and that fuel consumption is normal.
l Check for fuel, oil, and fluid leakage
l Check transmission oil level*.
l Check condition of drive belts.
l Check state of the battery's charge.
l Examine tires carefully (the spare tire as well), and replace those th\
at are worn. Check tire pressures.
l The brakes, front wheel alignment, and steering gear should be checked b\
y your Volvo retailer only.

Normally, the coolant does not need to be changed. If the system must be\
drained, consult your Volvo
retailer.
NOTE: Do not top off with water only. This reduces the rust-protective and ant\
ifreeze qualities of the
coolant and has a lower boiling point. It can also cause damage to the c\
ooling system if it should freeze.
Top off with Volvo Genuine Coolant/Antifreeze only (a 50/50 mix of wate\
r and antifreeze). CAUTION
The cooling system must always be kept filled to the correct level. If i\
t is not kept filled, there can be
high local temperatures in the engine which could result in damage. Diff\
erent types of antifreeze/
coolant may not be mixed.
WARNING!
Never remove the radiator cap while the engine is warm. Wait until the v\
ehicle
cools.
