7. Brake failure warning lightIf this light comes on while driving
or braking, stop the car as quickly
as possible in a safe place, open
the hood, and check the brake fluid
level in the reservoir, see
page 218 for the location of the
reservoir.
NOTE
Canadian models are equipped with the
second symbol.
WARNING
If the fluid level is below the MIN mark in the
reservoir or if a BRAKE FAILURE STOP
SAFELY message is displayed in the infor-
mation display: DO NOT DRIVE. Have the
car towed to a trained and qualified Volvo
service technician and have the brake sys-
tem inspected.
If the BRAKES and ABS warning lights come
on at the same time, this could indicate a fault
in the brake system.
In this case:
1. Stop the car in a suitable place and switch
off the engine.2. Restart the engine.
3. If both warning lights go off, no further
action is required and the car can be
driven.
4. If both lights remain on after the engine has
been restarted, switch off the engine again
and check the brake fluid level, see
page 218 for the location of the reservoir.
Door open warning
The driver will be alerted if one of the doors, the
hood or the trunk are open or ajar.
At low speedsIf the car is moving at a speed of
less than approximately 3 mph
(5 km/h), the Information symbol in
the instrument panel will light up
and a message will be shown in the
information display indicating which door(s),
etc is not completely closed.
At higher speedsIf the car is moving at a speed
above approximately 6 mph
(10 km/h), the Warning symbol in
the instrument panel will light up
and a message will be shown in the
information display indicating which door(s),
etc is not completely closed.

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 9 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
car is in water, do not attempt to restart
the engine. Have the car towed out of
the water.
Cold weather precautions
If you wish to check your vehicle before the
approach of cold weather, the following advice
is worth noting:
•Make sure that the engine coolant contains
50 percent antifreeze. Any other mixture
will reduce freeze protection. This gives
protection against freezing down to –31 °F
(–35 °C). See section "Coolant". The use of
"recycled" antifreeze is not approved by
Volvo. Different types of antifreeze must
not be mixed.
•Volvo recommends using only genuine
Volvo antifreeze in your vehicle's radiator.
Your Volvo retailer stocks plenty of Volvo
engine coolant to help protect your vehicle
during cold weather.
•Try to keep the fuel tank well filled – this
prevents the formation of condensation in
the tank. In addition, in extremely cold
weather conditions it is worthwhile to add
fuel line de-icer before refueling.
•The viscosity of the engine oil is important.
Oil with low viscosity (thinner oil) improves
cold-weather starting as well as decreas-
ing fuel consumption while the engine is
warming up. For winter use, 5W-30 oil, par-
ticularly the synthetic type
1, is recom-
mended. Be sure to use good quality oil but
do not use cold-weather oil for hard drivingor in warm weather, see page 274 for more
information.
•The load placed on the battery is greater
during the winter since the windshield wip-
ers, lighting, etc. are used more often.
Moreover, the capacity of the battery
decreases as the temperature drops. In
very cold weather, a poorly charged bat-
tery can freeze and be damaged. It is there-
fore advisable to check the state of charge
more frequently and spray an anti-rust oil
on the battery posts.
•Volvo recommends the use of snow tires
on all four wheels for winter driving – see
the chapter "Wheels and tires."
•To prevent the washer fluid reservoir from
freezing, add washer solvents containing
antifreeze (see page 218 for the location of
the washer fluid reservoir). This is impor-
tant since dirt is often splashed on the
windshield during winter driving, requiring
the frequent use of the washers and wip-
ers. Volvo Washer Solvent should be dilu-
ted 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 sol-
vent and 3 parts water Down to 0 °F
(–18 °C): 1 part washer solvent and 2 parts
1Synthetic oil is not used when the oil is changed at the normal maintenance intervals except at owner request and at additional charge. Please consult your Volvo retailer.

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. Driving or having the engine run-
ning for approximately 15 minutes will help
keep the battery charged.
•The optional 12 volt socket in the trunk
(certain models only) provides electricalcurrent 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.

147 To start the engine
WARNING
Before starting, check that the seat, steering
wheel and mirrors are adjusted properly.
Make sure the brake pedal can be
depressed completely. Adjust the seat if
necessary.
1. Fasten the seat belt.
2. Apply the parking brake if not already set.
The gear selector should be locked in the
Park (P) position (Shiftlock). See also page
152.
NOTE
After a cold start, idle speed may be notice-
ably higher than normal for a short period.
This is done to help bring components in the
emission control system to their normal
operating temperature as quickly as possi-
ble, which enables them to control emis-
sions and help reduce the vehicle's impact
on the environment.
3. The vehicle is equipped with an autostart
feature. Without touching the throttle
pedal, turn the key to position III and
release it. The starter motor will then oper-ate automatically (for up to ten seconds)
until the engine starts. If the engine fails to
start, repeat this step.
4. To release the gear selector from the Park
(P) position, the engine must be running (or
the ignition key must be in position II) and
the brake pedal must be depressed.
5. Select the desired gear. The gear engages
after a very slight delay, which is especially
noticeable when selecting R.
NOTE
•Immobilizer: If two of the keys to your
vehicle are close together, e.g., on the
same key ring when you try to start the
vehicle, this could cause interference in
the immobilizer system and result in the
vehicle not starting. If this should occur,
remove one of the keys from the key
ring before trying to start the vehicle
again.
•Keylock: The automatic transmission
has a keylock system. When the engine
is switched off, the gear selector must
be in the Park (P) position before the key
can be removed from the ignition
switch
1.
•When starting in cold weather, an auto-
matic transmission may shift up at
slightly higher engine speeds than nor-
mal until the automatic transmission
fluid reaches normal operating tem-
perature.
•Do not race a cold engine immediately
after starting. Oil flow may not reach
some lubrication points fast enough to
prevent engine damage.
1The optional keyless drive start control does not need to be removed from the ignition switch.

WARNING
•Volvo's floor mats are specially manu-
factured for your car. They must be
firmly secured in the clips on the floor so
that they cannot slide and become trap-
ped under the pedals on the driver's
side.
•Always place the gear selector in Park
(P) and apply the parking brake before
leaving the vehicle. Never leave the
vehicle unattended with the engine run-
ning.
•Always open garage doors fully before
starting the engine inside a garage to
ensure adequate ventilation. The
exhaust gases contain carbon monox-
ide, which is invisible and odorless but
very poisonous.
CAUTION
Automatic transmission: The engine
should be idling when you move the gear
selector. Never accelerate until after you
feel the transmission engage! Accelerating
immediately after selecting a gear will cause
harsh engagement and premature trans-
mission wear. Selecting P or N when idling
at a standstill for prolonged periods of time
will help prevent overheating of the auto-
matic transmission fluid.

Brake system

153 Brake lights
The brake lights come on automatically when
the brakes are applied.
Adaptive brake lightsThe adaptive brake lights activate in the event
of sudden braking or if the ABS system is acti-
vated. This function causes an additional tail-
light on each side of the vehicle to illuminate to
help alert vehicles traveling behind.
The adaptive brake lights activate if:
•The ABS system activates for more than
approximately a half second
•In the event of sudden braking while the
vehicle is moving at speeds above approx-
imately 6 mph (10 km/h)
When the vehicle has come to a stop, the brake
lights and additional taillights remain on for as
long as the brake pedal is depressed or until
braking force on the vehicle is reduced.
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.
For optimal ABS braking effect:1. Press down on the brake pedal with full
force. The pedal will pulsate.
2. Steer the vehicle in the direction of travel
and keep the brake pedal depressed.
Electronic Brake Force Distribution
(EBD)
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 switching of the ABS modulator will be
audible and the brake pedal will pulsate during
braking. Please be aware that ABS does not
increase the absolute braking potential of the
vehicle. While control will be enhanced, ABS
will not shorten stopping distances on slippery
surfaces.
If the warning lamp lights up there is a mal-
function of the ABS system (the standard brak-
ing system will still function) and the vehicle
should be driven cautiously to a trained and
qualified Volvo service technician for inspec-
tion.
WARNING
If the BRAKES and ABS warning symbols
light at the same time, there may be a prob-
lem in the brake system. If the brake fluid
level is normal in these circumstances, drive
carefully to a trained and qualified Volvo
service technician to have the brake system
checked.
Emergency Brake Assistance – EBAEBA is designed to provide full brake effect
immediately in the event of sudden, hard brak-
ing. The system is activated by the speed with
which the brake pedal is depressed.
When the EBA system is activated, the brake
pedal will go down and pressure in the brake
system immediately increases to the maximum
level. Maintain full pressure on the brake pedal
in order to utilize the system completely. EBA
is automatically deactivated when the brake
pedal is released.
