water Down to –18 °F (–28 °C): 1 part
washer solvent and 1 part water.
•Use Volvo Teflon Lock Spray in the locks.
NOTE
Avoid using de-icing sprays as they can
cause damage to the locks.
Conserving electrical current
Keep the following in mind to help minimize
battery drain:
•When the engine is not running, avoid turn-
ing the ignition key to position II. Many
electrical systems (the audio system, the
optional navigation system, power win-
dows, etc) will function with the ignition key
in position I. This position reduces 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 running
could result in the battery being completely
drained.
•The optional 12 volt socket in the trunk
(certain models only) provides electrical
current even with the ignition switched off,
which drains the battery.
NOTE
•If the ignition is switched on, a warning
message will be displayed in the text
window in the instrument panel when
the battery charge is low.
•An energy conserving function
designed into the vehicle's electrical
system will switch off certain functions
or reduce the load on the battery by,
e.g., reducing the audio system's vol-
ume.
Before a long distance trip
It is always worthwhile to have your vehicle
checked at a trained and qualified Volvo serv-
ice technician before driving long distances.
Your trained and qualified Volvo service tech-
nician will also be able to supply you with
bulbs, fuses, spark plugs 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:
•Check that engine runs smoothly and that
fuel consumption is normal.
•Check for fuel, oil, and fluid leakage
•Have the transmission oil level checked2.
•Check condition of drive belts.
•Check state of the battery's charge.
•Examine tires carefully (the spare tire as
well), and replace those that are worn.
Check tire pressures.
•The brakes, front wheel alignment, and
steering gear should be checked by your
Volvo retailer only.
•Check all lights, including high beams.
•Reflective warning triangles are legally
required in some states/provinces.
•Have a word with your Volvo retailer if you
intend to drive in countries where it may be
difficult to obtain the correct fuel.
•Consider your destination. If you will be
driving through an area where snow or ice
are likely to occur, consider snow tires.
2To 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 qualified Volvo service technician.

06 Starting and driving
Brake system

150
Brake circuit malfunction
The 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 Volvo
retailer and have the brake system inspec-
ted.
Power brakes function only when the
engine is running
The 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, consider-
ably higher pressure will be required on the
brake pedal to compensate for the lack of
power assistance. This can happen for exam-
ple when towing your vehicle or if the engine is
switched off when the vehicle is rolling. The
brake pedal feels harder than usual.
Water on brake discs and brake pads
affects braking
Driving 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 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 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 brakes (ABS)
The 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 self-diagnostic test
when the engine is started and when the
vehicle first reaches a speed of approxi-
mately 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.

06 Starting and driving
Stability system
06
152
Dynamic Stability Traction Control
(DSTC)
The stability system consists of a number of
functions designed help reduce wheel spin,
counteract skidding, and to generally help
improve directional stability.
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 the stability system'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.
Temporarily switching off Spin control1. Turn the thumbwheel (A) on the left-side
steering wheel lever until the DSTC menu
is displayed.
2.
Hold down the RESET button (B) to toggle
between
DSTC SPIN CONTROL ON orOFF.
NOTE
•The message DSTC SPIN CONTROL
OFF indicates that the stability sys-
tem's spin control function has tempo-
rarily been switched off.
•The stability control indicator light
will illuminate and remain on until spin
control has been reactivated.
•The spin control function is automati-
cally enabled each time the engine is
started.
•DSTC ON indicates that all system
functions are active.
Active yaw control – AYC (DSTC only)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.

•Sling-type equipment applied at the front
will damage radiator and air conditioning
lines.
•It is equally important not to use sling-type
equipment at the rear or apply lifting equip-
ment inside the rear wheels; serious dam-
age to the rear axle may result.
•If the vehicle is being towed on a flat bed
truck, the towing eyelets must not be used
to secure the vehicle on the flat bed. Con-
sult the tow truck operator.
WARNING
•Remember that the power brakes and
power steering will not function when
engine is not running. The braking and
steering systems will function but con-
siderably higher pressure will be
required on the brake pedal and greater
steering effort must be exerted.
•The towing eyelets must not be used for
pulling the vehicle out of a ditch or for
any similar purpose involving severe
strain. Do not use the towing eyelets to
pull the vehicle up onto a flat bed tow
truck.
