All Wheel Drive
All Wheel Drive (AWD) - general information
Your Volvo can be equipped with permanent All Wheel Drive (option), wh\
ich means that power is
distributed automatically between the front and rear wheels. Under norma\
l driving conditions, most of
the engine's power is directed to the front wheels. However, if there is\
any tendency for the front wheels
to spin, an electronically controlled coupling distributes power to the \
wheels that have the best traction.
Tire dimensions
Volvo recommends that you always drive on tires of the same brand, size,\
construction (radial), tread
pattern, load-, speed-, traction-, temperature-, and treadwear rating. N\
ever drive on mixed tires, except
for brief periods when the temporary spare tire is in use.
Always use properly inflated tires of correct dimensions. Tire size and \
inflation pressures are shown on
the tire inflation pressure placards, located on the driver's side B-pil\
lar (the structural member at the side
of the vehicle, at the rear of the driver's door opening), or on the in\
side of the fuel filler door on
Canadian models.
Temporary Spare
The temporary spare tire is for temporary, lowspeed, short-distance use \
only. Replace it with a full-sized
tire as soon as possible. Do not drive on the temporary spare at speeds \
above 50 m.p.h. (80km/h) or for
distances greater than 50 miles (80 km).
Never install snow chains on a temporary spare.

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 140 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.

Dynamic Stability Traction Control (DSTC) (contd)
The Stability Control indicator light
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.
l Roll Stability Control is actively functioning to help avoid a roll-over\
situation.
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" will be displayed in the text window. If this occurs, stop the\
vehicle in a suitable place,
switch off and restart the engine. If the light remains on, an authorize\
d Volvo retailer should check the
system.
l In the event of high brake temperature, "TRACTION CONTROL TEMPORARILY OF\
F" will be
displayed in the text window.
The system will automatically switch on again when the brakes have coole\
d.
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.
NOTE:
l 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. Maintain full pressure on th\
e brake pedal in order to utilize
the system completely. EBA is automatically deactivated when the brake p\
edal is released.
l When the vehicle has been parked for some time, the brake pedal may sink\
more than usual when the
engine is started. This is normal and the pedal will return to its usual\
position when it is released.

NOTE:
l Recommended hitch tongue load: not more than 10% of the trailer's weight\
.
The trailer load should be positioned so that it does not shift and the \
tongue load should be 10% of the
trailer's weight. However, the tongue load should not exceed the maximum\
permissible weights
indicated in the table above.
l When towing trailers without brakes, the maximum permissible trailer wei\
ght is 1,700 lbs (750 kg).
l If necessary, redistribute the weight of any cargo in the trailer to avo\
id excessive weight on the trailer
hitch.
l The maximum trailer weight listed in the table for All Wheel Drive model\
s, 5,000 lbs (2250 kg) is
only applicable when there are not more than two occupants in the vehicl\
e, in the front seats, with a

l The maximum weight listed for Front Wheel Drive models, 4,000 lbs (1800\
kg) is only applicable
when there are not more than four occupants in the vehicle, in the front\
seats and second row of seats,
with a combined weight of 600 lbs (270 kg), with no other cargo in the\
vehicle.
l Please be aware that the load on the trailer hitch is part of the vehicl\
e's total load carrying capacity.
The amount of cargo in the vehicle and the trailer must be limited so th\
at the gross vehicle weight and
maximum permissible rear axle weight
(see page 165) are not exceeded.
l Vehicles used for towing a trailer on a regular basis, or for long-dista\
nce highway towing should be
equipped with an automatic transmission oil cooler and Volvo's automatic\
self-leveling system for the
rear suspension. Consult your Volvo retailer.
l Volvo recommends the use of Volvo trailer hitches that are specially des\
igned for the vehicle.

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 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 140 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 26).
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. 110 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.
l Check all lights, including high beams.
l Reflective warning triangles are legally required in some states/provinc\
es.
l Have a word with your Volvo retailer if you intend to drive in countries\
where it may be difficult to
obtain the correct fuel.
l Consider your destination. If you will be driving through an area where \
snow or ice are likely to
occur, consider snow tires.
* To prevent injury from contact with hot surfaces, do not inspect your \
vehicle's transmission fluid
yourself. Have your vehicle's transmission fluid level inspected by a qu\
alified Volvo service technician.
