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 when towing a
trailer. Vehicle speed is usually slower, which means that the cooling o\
f the brakes is less efficient than
when driving on level roads. To reduce the strain on the brakes, shift i\
nto a lower gear and let the engine
help with the braking. Do not forget that if you are towing a trailer, t\
he brakes will be subjected to a
greater than normal load.

Brake system (contd)
Anti-lock brakes (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.
This system performs a self-diagnostic test when the engine is started a\
nd 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.
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 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
brake fluid level (see
page 126 for the location of the brake fluid reservoir).
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.
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.

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

improve 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 DSTC button on the center control panel for at leas\
t a half a second.
When the SC function has been switched off:
l The text window will briefly display "DSTC SPIN CONTROL OFF"
l The LED in the DSTC button will be off.
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 vehicle shows a tendency to skid or slide laterally\
. This is done by activating the
Anti-lock Braking System. A pulsating sound will be audible when the fun\
ction 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.
4. Roll Stability Control (RSC)
RSC utilizes a gyro-sensor to monitor the vehicle's angle of inclination\
, and the rate at which this angle
changes. If necessary, RSC activates the Anti-lock Brake System to brake\
one or more of the wheels to
help maintain stability. A pulsating sound will be audible when the func\
tion 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 one of the DSTC system's permanent functions and is not affected\
when the DSTC button on the
center control panel is pressed.
The DSTC button
The DSTC button in the center control panel is used to switch the Spin C\
ontrol (SC) function on or off.
The button must be pressed for at least a half second to prevent SC from\
being switched off
inadvertently.
When the system has been switched off, the green indicator lamp in the b\
utton will go out and "DSTC
SPIN CONTROL OFF" will be displayed in the text window.
All DSTC functions are (re)activated each time the engine is started.

l While the vehicle is being towed, try to keep the tow rope taut at all t\
imes.
l The vehicle should only be towed in forward direction.
CAUTION
- Please check with state and local authorities before attempting this t\
ype of towing, as vehicles being
towed are subject to regulations regarding maximum towing speed, length \
and type of towing device,
lighting, etc.
- If the vehicle's battery is dead, do not attempt to start the vehicle \
by pushing or pulling it as this will
damage the three-way catalytic converter(s). The engine must be jump s\
tarted using an auxiliary
battery (see

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.

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.

CAUTION
- During high pressure washing, the spray mouthpiece must never be close\
r to the vehicle than
13" (30 cm). Do not spray into the locks.
- When washing or steam cleaning the engine, avoid spraying water or ste\
am directly on the electrical
components or toward the rear side of the engine.
Special moonroof cautions:
- Always close the moonroof and visor before washing your vehicle.
- Never use abrasive cleaning agents on the moonroof.
- Never use wax on the rubber seals around the moonroof.
l After cleaning the engine, the spark plug wells should be inspected for \
water and blown dry if
necessary.
Suitable detergents: Special vehicle washing detergents should be used. A suitable mixture i\
s about 2.5
fl. oz. (8.5 cl) of detergent to 2.6 US gal. (10 liters) of warm wat\
er. After washing with a detergent the
vehicle should be well rinsed with clean water.
Bumpers: Wash the bumpers with the same cleaning agent used on the rest of the v\
ehicle. Never clean
the bumpers with gasoline or paint thinner. Difficult spots can be remov\
ed with denatured alcohol. To
avoid scratches, do not dry the bumpers with paper.
NOTE: When washing the vehicle, remember to remove dirt from the drain holes i\
n the doors and sills.
WARNING!
When the vehicle is driven immediately after being washed, apply the bra\
kes several times in order to
remove any moisture from the brake linings.
Engine cleaning agents should not be used when the engine is warm. This \
constitutes a fire risk.
pg. 119 Vehicle care
Automatic washing - simple and quick
l We do NOT recommend washing your vehicle in an automatic wash during the\
first six months
(because the paint will not have hardened sufficiently).
l An automatic wash is a simple and quick way to clean your vehicle, but i\
t is worth remembering that
it may not be as thorough as when you yourself go over the vehicle with \
sponge and water. Keeping the
underbody clean is most important, especially in the winter. Some automa\
tic washers do not have
facilities for washing the underbody.
l Before driving into an automatic car wash, make sure that side view mirr\
ors, auxiliary lamps, etc, are
secure, and that any antenna(s) are retracted or removed. Otherwise th\
ere is risk of the machine

CAUTION
The vehicle must not be driven with wheels of different dimensions or wi\
th a spare tire other than the
one that came with the vehicle. The use of different size wheels can ser\
iously damage your vehicle's
transmission.
pg. 109 Wheels and tires
Snow chains
Snow chains can be used on your Volvo with the following restrictions:
l Snow chains should be installed on front wheels only. Use only Volvo app\
roved snow chains.
l If accessory, aftermarket or "custom" tires and wheels are installed and\
are of a size different than the
original tires and wheels, chains in some cases CANNOT be used. Sufficie\
nt clearances between chains
and brakes, suspension and body components must be maintained.
l Some strap-on type chains will interfere with brake components and there\
fore CANNOT be used.
l All Wheel Drive models: Snow chains should only be installed on the front wheels. Only chains
adapted for AWD models should be used.
NOTE: Consult your Volvo retailer for additional snow chain information.
CAUTION
- Check local regulations regarding the use of snow chains before instal\
ling. Always follow the chain
manufacturer's installation instructions carefully. Install chains as ti\
ghtly as possible and retighten
periodically.
- Never exceed the chain manufacturer's specified maximum speed limit. (\
Under no circumstances
should you exceed 31 mph 50 km/h)
- Avoid bumps, holes or sharp turns when driving with snow chains.
- The handling of the vehicle can be adversely affected when driving wit\
h chains. Avoid fast or sharp
turns as well as locked wheel braking.
Snow tires, studded tires*
Tires for winter use:
Owners who live in or regularly commute through areas with sustained per\
iods of snow or icy driving
conditions are strongly advised to fit suitable winter tires to help ret\
ain the highest degree of traction.
It is important to install winter tires on all four wheels to help retai\
n traction during cornering, braking,
and accelerating. Failure to do so could reduce traction to an unsafe le\
vel or adversely affect handling.
Do not mix tires of different design as this could also negatively affec\
t overall tire road grip.
