Brake systemThe brake system is a hydraulic system con-
sisting of two separate brake circuits. If a prob-
lem should occur in one of these circuits, it is
still possible to stop the vehicle with the other
brake circuit.
If the brake pedal must be depressed farther
than normal and requires greater 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 check 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 or if a brake system message is
shown in the information display:
DO NOT
DRIVE
. Have the vehicle towed to a trained
and qualified Volvo service technician and
have the brake system inspected.
Power brakes function only when the
engine is runningThe power brakes utilize vacuum pressure
which is only created when the engine is run-
ning. 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 approximately five
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 roll-
ing. The brake pedal feels harder than usual.Water on brake discs and brake pads
affects brakingDriving in rain and slush or passing through an
automatic car wash can cause 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 occa-
sionally 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 weather.Severe strain on the brake systemThe brakes will be subject to severe strain
when driving in mountains or hilly areas, or
when towing a trailer. Vehicle speed is usuallyslower, which means that the cooling of the
brakes is less 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 will be subjected to
a greater than normal load.
Anti-lock braking systemThe Anti-lock Braking System (ABS) helps to
improve vehicle control (stopping and steering)
during severe braking conditions by limiting
brake lockup. When the system "senses"
impending lockup, braking pressure is auto-
matically modulated in order to help prevent
lockup that could lead to a skid.
The system performs a brief self-diagnostic
test when the engine has been started and
driver releases the brake pedal. Another auto-
matic test may be performed when the vehicle
first reaches a speed of approximately 25 mph
(40 km/h). The brake pedal will pulsate several
times and a sound may be audible from the
ABS control module. This is normal.Cleaning the brake discsCoatings of dirt and water on the brake discs
may result in delayed brake function. This delay
is minimized by cleaning the brake linings.
Cleaning the brake pads is advisable in wet
weather, prior to long-term parking, and after
the vehicle has been washed. Do this by brak-

04154
IntroductionThe Dynamic Stability and Traction Control
system (DSTC) consists of a number of func-
tions designed help reduce wheel spin, coun-
teract skidding, and to generally help improve
directional stability.
CAUTION
A pulsating sound will be audible when the
system is actively operating and is normal.Traction control (TC)This function is designed to help reduce wheel
spin by transferring power from a drive wheel
that begins to lose traction to the wheel on the
opposite side of the vehicle (on the same axle).
TC is most active at low speeds.
This is one of DSTC's permanent functions and
cannot be switched off.Active Yaw Control (AYC)This function helps maintain directional stabil-
ity, for example when cornering, by braking
one or more of the wheels if the vehicle shows
a tendency to skid or slide laterally.
This is one of DSTC's permanent functions and
cannot be switched off.
Spin control (SC)The spin control function is designed to help
prevent the drive wheels from spinning while
the vehicle is accelerating.
Under certain circumstances, such as when
driving with snow chains, or driving in deep
snow or loose sand, it may be advisable to
temporarily switch off this function for maxi-
mum tractive force.
WARNING
The car's handling and stability characteris-
tics will be altered if the spin control function
has been disabled.Operation

General informationEconomical driving conserves natural
resourcesBetter driving economy may be obtained by
thinking ahead, avoiding rapid starts and stops
and adjusting the speed of your vehicle to
immediate traffic conditions.
Observe the following rules:•
Bring the engine to normal operating tem-
perature as soon as possible by driving
with a light foot on the accelerator pedal for
the first few minutes of operation. A cold
engine uses more fuel and is subject to
increased wear.
•
Whenever possible, avoid using the vehicle
for driving short distances. This does not
allow the engine to reach normal operating
temperature.
•
Drive carefully and avoid rapid acceleration
and hard braking.
•
Use the transmission's Drive (D) position
as often as possible and avoid using kick-
down.
•
Do not exceed posted speed limits.
•
Avoid carrying unnecessary items (extra
load) in the vehicle.
•
Maintain correct tire pressure. Check tire
pressure regularly (when tires are cold).
•
Remove snow tires when threat of snow or
ice has ended.
•
Note that roof racks, ski racks, etc,
increase air resistance and also fuel con-
sumption.
•
At highway driving speeds, fuel consump-
tion will be lower with the air conditioning
on and the windows closed than with the
air conditioning off and the windows open.
•
Using the onboard trip computer's fuel
consumption modes can help you learn
how to drive more economically.
Other factors that decrease gas mileage
are:
•
Dirty air cleaner
•
Dirty engine oil and clogged oil filter
•
Dragging brakes
•
Incorrect front end alignment
Some of the above mentioned items and others
are checked at the standard maintenance
intervals.
WARNING
Driving with the trunk open: Driving with
the trunk open could lead to poisonous
exhaust gases entering the passenger com-
partment. If the trunk must be kept open for
any reason, proceed as follows:•
Close the windows
•
Set the ventilation system control to air
flow to floor, windshield and side win-
dows and the blower control to its high-
est setting.
Weight distribution affects handlingAt the specified curb weight your vehicle has a
tendency to understeer, which means that the
steering wheel has to be turned more than
might seem appropriate for the curvature of a
bend. This ensures good stability and reduces
the risk of rear wheel skid. Remember that
these properties can alter with the vehicle load.
The heavier the load in the trunk, the less the
tendency to understeer.Handling, roadholdingVehicle load, tire design and inflation pressure
all affect vehicle handling. Therefore, check
that the tires are inflated to the recommended
pressure according to the vehicle load. See the
"Tire pressure" section. Loads should be dis-
tributed so that capacity weight or maximum
permissible axle loads are not exceeded.

Driving through water•
The vehicle can be driven through water up
to a depth of approximately 10 in. (25 cm),
at a maximum speed of 6 mph (10 km/h).
•
Take particular care when driving through
flowing water.
•
Clean the electrical connections for trailer
wiring after driving in mud or water.
•
When driving through water, maintain low
speed and do not stop in the water.WARNING
After driving through water, press lightly on
the brake pedal to ensure that the brakes
are functioning normally. Water or mud can
make the brake linings slippery, resulting in
delayed braking effect.
CAUTION
•
Engine damage will occur if water is
drawn into the air cleaner.
•
If the vehicle is driven through water
deeper than 10 in (25 cm), water may
enter the differential and the transmis-
sion. This reduces the oil's lubricating
capacity and may shorten the service
life of these components.
•
Do not allow the vehicle to stand in
water up to the door sills longer than
absolutely necessary. This could result
in electrical malfunctions.
•
If the engine has been stopped while the
vehicle is in water, do not attempt to
restart it. Have the vehicle towed out of
the water.
Engine and cooling systemUnder special conditions, for example when
driving in hilly terrain, extreme heat or with
heavy loads, there is a risk that the engine and
cooling system will overheat. Proceed as fol-
lows to avoid overheating the engine.•
Maintain a low speed when driving with a
trailer up long, steep hills.
•
Do not turn the engine off immediately
when stopping after a hard drive.
WARNING
The cooling fan may start or continue to
operate (for up to 6 minutes) after the engine
has been switched off.•
Remove any auxiliary lights from in front of
the grille when driving in hot weather con-
ditions.
•
Do not exceed engine speeds of 4500 rpm
if driving with a trailer in hilly terrain. The oil
temperature could become too high.
Conserving electrical currentKeep the following in mind to help minimize
battery drain:•
When the engine is not running, avoid
using ignition mode II. Many electrical sys-
tems (the audio system, the optional navi-
gation system, power windows, etc) will
function in ignition modes 0 and I. These
modes reduce drain on the battery.
•
Please keep in mind that using systems,
accessories, etc., that consume a great
deal of current when the engine is not run-
ning could result in the battery being com-
pletely drained.
•
The optional 12 volt socket in the trunk
provides electrical current even with the
ignition switched off, which drains the bat-
tery.

When low inflation pressure is detected, TPMS
will light up the tire pressure warning light
(
) (also referred to as a telltale) in the
instrument panel, and will display a message in
the text window. The wording of this message
is determined by the degree of inflation pres-
sure loss.NOTE
If a fault occurs in TPMS, the tire pressure
warning light will flash for approximately
1 minute and
TIRE PRESS SYST
SERVICE REQUIRED
will be displayed.
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation
pressure label, you should determine the
proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres-
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon aspossible, and inflate them to the proper pres-
sure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect the
vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv-
er's responsibility to maintain correct tire pres-
sure, even if under-inflation has not reached
the level to trigger illumination of the TPMS low
tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale. When the system
detects a malfunction, the telltale will flash for
approximately one minute and then remain
continuously illuminated. This sequence will
continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the mal-
function indicator is illuminated, the system
may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may
occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing oneor more tires or wheels on your vehicle to
ensure that the replacement or alternate tires
and wheels allow the TPMS to continue to
function properly.
NOTE
TPMS indicates low tire pressure but does
not replace normal tire maintenance. For
information on correct tire pressure, please
refer to the Tire inflation pressure tables or
consult your Volvo retailer.Erasing warning messagesWhen a low tire pressure warning message has
been displayed, and the tire 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 pressure placard or the
tables on pages 246 and 247.
3. In certain cases, it may be necessary to
drive the vehicle for several minutes at a
speed of 20 mph (30 km/h) or faster. This
will erase the warning text and the warning
light will go out.
