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: It may be necessary to deactivate one or both of the park assist system\
s in certain cases.
l Rear park assist: towing a trailer, carrying bicycles in a rear-mounted carrier, etc, co\
uld trigger the
rear park assist system's sensors.
l Front park assist: it may not be possible to combine auxiliary headlights and front park \
assist since
these lights could trigger the system's sensors.
Faults in the system
If a fault should occur in the system, the LED in the button will be swi\
tched off and a message will be
displayed in the text window.
Cleaning the sensors
For the system to function properly, the sensors in the front and/or rea\
r bumpers should be kept clean.
They can be cleaned with car washing detergent and a sponge.
WARNING!
This system is designed to be a supplementary aid when the vehicle is ba\
cking up. It is not, however,
intended to replace the driver's attention and judgement.

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.

Tire Pressure Monitoring System (TPMS) - option on certain U.S. models\
only
The tire pressure monitoring system uses sensors mounted in the tire val\
ves to check inflation pressure
levels. When the vehicle is moving at a speed of 20 mph (30 km/h) or f\
aster, these sensors transmit
inflation pressure data to a receiver located in the vehicle.
USA - FCC ID: MRXTG315AM04 This device complies with part 15 of the FCC \
rules. Operation is
subject to the following conditions: (1) This device may not cause har\
mful interference, and (2) this
device must accept any interference received, including interference tha\
t may cause undesired operation.
When low inflation pressure is detected, TPMS will light up the tire pre\
ssure warning light ( ) in the
instrument panel, and will display a message in the text window. The wor\
ding of this message is
determined by the degree of inflation pressure loss.
When the tire pressure monitoring system warning light is on, one or mor\
e of your tires is significantly
under-inflated. You should stop and check your tires as soon as possible\
, and inflate them to the proper
pressure as indicated on the vehicle's tire information placard.
Driving on a significantly under-inflated tire causes the tire to overhe\
at and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire tread life, and ma\
y affect the vehicle's handling and
stopping ability. Each tire, including the spare, should be checked mont\
hly when cold and set to the
recommended inflation pressure as specified in the vehicle placard and o\
wner's manual.
NOTE: TPMS indicates low tire pressure but does not replace normal tire maint\
enance. For information
on correct tire pressure, please refer to the table on
page 115, or consult your Volvo retailer.

Erasing warning messages
When a low tire pressure warning message has been displayed, and the tir\
e pressure warning light has
come on:
1. Use a tire pressure gauge to check the inflation pressure of all four\
tires.
2. Re-inflate the tire(s) to the correct pressure (consult the tire p\
ressure placard or the table on
page 115).
3. Drive the car for at least one minute at a speed of 20 mph (30 km/h)\
or faster. This will erase the
warning text and the warning light will go out.
WARNING!
Incorrect inflation pressure could lead to tire failure, resulting in a \
loss of control of the
vehicle.
Changing tires
Please note the following when changing or replacing the factory install\
ed TPMS wheels/tires on the
vehicle:
Only the factory-mounted wheels are equipped with TPMS sensors in the va\
lves.
If the vehicle is equipped with a temporary spare tire, this tire does n\
ot have a TPMS sensor.
If, for example, winter wheels/tires are used that are not equipped with\
TPMS sensors, the message
TIRE PRESSURE SYSTEM SERVICE REQUIRED will be displayed after the car ha\
s been driven for
several minutes at approximately 35 mph (50 km/h) or faster.
This message will remain on until wheels with TPMS sensors are mounted o\
n the vehicle and it has been
driven for at least one minute at a speed of 20 mph (30 km/h) or faste\
r.
pg. 117 Wheels and tires
TPMS valves can be fitted on winter wheels or full-size spare wheels/tir\
es. Consult your Volvo retailer.
CAUTION:
When inflating tires with TPMS valves, press the pump's mouthpiece strai\
ght onto the valve to help
avoid bending or otherwise damaging the valve.
