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
153.
Manual transmission: The clutch must be
fully depressed.
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. On models with an
automatic transmission, 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: Models equipped an auto-
matic transmission have a keylock sys-
tem. 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, the
transmission may shift up at slightly
higher engine speeds than normal until
the automatic transmission fluid rea-
ches normal operating temperature.
•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.

06 Starting and driving
Brake system
06

155 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.

157 Stability Traction Control (STC)/
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.

NOTE
•The message STC/DSTC SPIN
CONTROL OFF indicates that the sta-
bility system's spin control function has
temporarily 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.
•STC/DSTC ON indicates that all sys-
tem 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.
1Models equipped with All Wheel Drive (AWD) have an integrated traction control function that cannot be disabled. DSTC is optional on AWD models.

159 Emergency towing
G030710
The towing eyelet is located under the floor of
the trunk. This eyelet must be screwed into the
positions provided on the right sides of either
the front or rear bumper (see the illustration).
To attach the towing eyelet:1. Press the mark on the lower edge of the
cover (1) to open it.
2. Screw the towing eyelet (3) in place first by
hand and then using the tire iron until it is
securely in place.

After the vehicle has been towed, the eye-
let should be removed and returned to its
storage space.
Press the cover back into position.
WARNING
Do not use the towing eyelets to pull the
vehicle up onto a flat bed tow truck.
Towing a vehicle with all four wheels on
the ground
WARNING
Volvo does not recommend towing a disa-
bled vehicle behind another vehicle. Signif-
icant difficulty in steering and braking, com-
bined with unfavorable weather, traffic, and
road conditions may make it impossible to
maintain vehicle control.
1. Apply the parking brake.
WARNING
Towing a vehicle with a locked steering
wheel will make the vehicle impossible to
steer.
2. Insert the key into the ignition to unlock the
steering wheel. The steering wheel must be
unlocked. With the engine off and the vehi-cle at a standstill, great effort will be
required to turn the steering wheel.
3.
Turn the ignition key to position II.
4. Place the gear selector in neutral. For vehi-
cles with automatic transmissions, follow
instruction on page 153, "Shiftlock over-
ride" to allow the gear selector to be moved
from the Park position.
5. Keep firm pressure on the brake pedal
while releasing the parking brake.
6. When towing has been completed, return
the gear selector to Park (automatic) or
Reverse (manual) and apply the parking
brake.
The following points should also be
observed:
•Never exceed 50 mph (80 km/h). Never
exceed local towing speed limits and heed
all local towing restrictions.
•Never tow farther than 50 miles (80 km).
•Keep the tow rope taut at all times while the
vehicle is in motion.
•The disabled vehicle should be towed in
the forward direction only.

WARNING
•Never allow a vehicle to be towed with-
out a driver behind the wheel of the dis-
abled vehicle.
•Never remove the key from the ignition
while the vehicle is moving. The steering
wheel could lock, making it impossible
to steer the vehicle.
•When the engine is not running, steering
resistance and the effort needed to
apply the brakes will be great.
•Never attempt to tow a vehicle with a
dead battery at night.
CAUTION
•Check with state and local authorities
before attempting this type of towing,
as vehicles being towed are subject to
regulations regarding maximum towing
speed, length and type of towing
device, lighting, marker flags, etc.
•Never attempt to push- or tow-start a
vehicle with a dead battery. This would
inject unburned fuel into the three-way
catalytic converter(s), causing over-
heating, backfiring, and damage, see
page 161 for instructions on jump star-
ting the vehicle.
Towing vehicles with front wheel drive
Volvo recommends the use of flat bed equip-
ment for towing vehicles with front wheel drive.
If wheel lift equipment must be used, please
use extreme caution to help avoid damage to
the vehicle.
In this case, the vehicle should be towed with
the rear wheels on the ground if at all possible.
If it is absolutely necessary to tow the vehicle
with the front wheels on the ground, please
refer to the towing information on the previous
page.
•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.

Tire Sealing System
07
194* Option/accessory, for more information, see Introduction.
Introduction
Certain models are equipped with a tire sealing
system* that enables you to temporarily seal a
hole in the tread surface and re-inflate a flat tire,
or to adjust a tire’s inflation pressure.
The system consists of an air compressor, a
container for the sealing compound, wiring to
connect the system to the vehicle’s electrical
system via one of the 12-volt sockets, and a
hose used to connect the system to the tire’s
inflation valve.
The 12-volt sockets are located in the front
tunnel console and on the rear side of the tun-
nel console, in the rear seat.
Accessing the tire sealing systemThe tire sealing system is stowed under the
floor of the trunk. To access it:
1. Lift the floor hatch in the trunk.
2. Lift out the tire sealing system.
NOTE
•The tire sealing system is only intended
to seal holes on the tire’s tread area, not
the sidewall.
•Tires with large holes or tears cannot be
repaired with the tire sealing system.
•After use, stow the tire sealing system
properly to help prevent rattling.
WARNING
•After using the tire sealing system, the
vehicle should not be driven farther than
approximately 120 miles (200 km).
•Have the tire inspected by a trained and
qualified Volvo service technician as
soon as possible to determine if it can
be permanently repaired or must be
replaced.
•The vehicle should not be driven faster
than 50 mph (80 km/h) while using a tire
that has been temporarily repaired with
the tire sealing system.
•After using the tire sealing system, drive
carefully and avoid abrupt steering
maneuvers and sudden stops.

WARNING
Please keep the following points in mind
when using the tire sealing system:
•The sealing compound bottle (no. 8 in
the illustration) contains 1.2-Ethanol
and natural rubber-latex. These sub-
stances are harmful if swallowed.
•The contents of this bottle may cause
allergic skin reactions or otherwise be
potentially harmful to the skin, the cen-
tral nervous system, and the eyes.
Precautions:
•Keep out of reach of children.
•Do not ingest the contents.
•Avoid prolonged or repeated contact
with the skin.
•Hands should be washed thoroughly
after handling.
First aid:
•Skin: Wash affected areas of skin with
soap and water. Get medical attention
if symptoms occur.
•Eyes: Flush with plenty of water for least
15 minutes, occasionally lifting the
upper and lower eyelids. Get medical
attention if symptoms occur.
•Inhalation: Move the person to fresh air.
If irritation persists, get medical atten-
tion.
Tire sealing system–temporarily
repairing a flat tire
G019723
Temporarily repairing a flat tire is done in two
stages:
•Stage 1: The hole is sealed by pumping
sealing compound into the tire. The car is
then driven a short distance to distribute
the sealing compound in the tire.
NOTE
Do not remove any foreign objects (nails,
etc.) from the tire before using the sealing
system.
•Stage 2: The tire’s inflation pressure is
checked and adjusted if necessary.
WARNING
•Never leave the tire sealing system
unattended when it is operating.
•Keep the tire sealing system away from
children.
•Be sure the vehicle is parked safely off
the road and away from moving traffic.
•Apply the parking brake.
Stage 1: Sealing the hole1. Open the cover on the tire sealing kit.
2. Peel off the speed limit sticker and affix it
to the steering wheel hub where it will be
clearly visible to the driver.
3. Ensure that the on/off switch is in posi-
tion 0 (the 0 side of the switch should be
pressed down).

12. Switch off the compressor and disconnect
the electrical wire from the 12-volt socket.
13. Unscrew the hose from the tire’s inflation
valve and reinstall the valve cap.
14. Immediately drive the vehicle for approxi-
mately 2 miles (3 km) at a maximum speed
of 50 mph (80 km/h) to distribute the seal-
ing compound in the tire.
CAUTION
If your vehicle is equipped with the Tire
Pressure Monitoring System (TPMS), the
use of the sealing compound may lead to
incorrect tire pressure readings or in rare
cases, damage to the tire pressure sensor.
Use the tire sealing system to check and
adjust the damaged tire's inflation pressure.
NOTE
•Safely stow the tire sealing system in a
convenient place as it will soon be used
again to check the tire’s inflation pres-
sure.
•The empty bottle of sealing compound
cannot be removed from the bottle
holder. Consult a trained and qualified
Volvo service technician to have the
bottle removed and properly disposed
of.
WARNING
If heavy vibrations, unsteady steering
behavior, or noises should occur while driv-
ing, reduce speed and park the vehicle in a
safe place. Recheck the tire for bumps,
cracks, or other visible damage, and
recheck its inflation pressure. If the pressure
is below 19 psi (1.3 bar), do not continue
driving. Have the vehicle towed to a trained
and qualified Volvo service technician.
Stage 2: Checking inflation pressure1. Connect the tire sealing system as descri-
bed in stage 1.
2. Refer to the inflation pressure tables for the
correct inflation pressure. If the tire needs
to be inflated, start the tire sealing system’s
compressor. If necessary, release air from
the tire by turning the air release knob
counterclockwise.
CAUTION
The compressor should not be used for
more than 10 minutes at a time to avoid
overheating.
WARNING
If you interrupt your trip for more than 1
hour, check the inflation pressure in the
damaged tire again before continuing.
Replacing the sealing compound
container
The sealing compound container must be
replaced if:
•the tire sealing system has been used to
repair a tire
•the container’s expiration date has passed
(see the date on decal).
NOTE
•After use, the sealing compound bottle,
the hose, and certain other system
components must be replaced. Please
consult your Volvo retailer for replace-
ment parts.
•If the sealing compound bottle’s expi-
ration date has passed, please take it to
a Volvo retailer or a recycling station
that can properly dispose of harmful
substances.
