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.

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.
