WARNING
•When the vehicle is being towed, the
ignition should be in mode II (in mode I,
all of the vehicle's airbags are deacti-
vated). See page 83 for more informa-
tion about ignition modes.
•Never remove the remote key from the
ignition slot when the vehicle is being
towed. For vehicles with keyless drive,
the remote key must remain inside the
vehicle.
•The power brakes and power steering
will not function when the engine is not
running. Approximately 5 times more
pressure will be required on the brake
pedal and the steering wheel will be
considerably harder to turn.
•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.
Towing the vehicle
1. With the remote key fully pressed into the
ignition slot1, press START/STOP
ENGINE for approximately 2 seconds to
activate ignition mode II.
2. The remote key must remain in the ignition
slot
2 for the entire time that the vehicle is
being towed.
3. Keep the tow rope taut when the towing
vehicle slows down by applying light pres-
sure on the brake pedal. This will help pre-
vent jarring movements of the vehicle
being towed.
4. Be prepared to apply the brakes to stop the
vehicle being towed.
CAUTION
General towing precautions:
•Please check with state and local
authorities before attempting this type
of towing, as vehicles being towed are
subject to regulations regarding maxi-
mum towing speed, length and type of
towing device, lighting, etc.
•If the vehicle's battery is dead, attach
jumper cables (see page 116) to provide
current for releasing the electric parking
brake and to move the gear selector
from the P position to N. If this is not
possible, see page 120 for information
about manually overriding the shiftlock
system to move the gear selector from
P to N.
•Maximum speed: 50 mph (80 km/h). Do
not exceed the maximum allowable
towing speed.
•Maximum distance with front wheels on
ground: 50 miles (80 km).
•The vehicle should only be towed in the
forward direction.
1Not necessary in vehicles with the optional keyless drive.2For vehicles with the the optional keyless dirive, the remote key must be in the vehicle.

at 6-year intervals, even if it has never been
used.
A tire's age can be determined by the DOT
stamp on the sidewall (see the illustration).
A tire with e.g., visible cracks or discoloration
should be replaced immediately.
Tread wear indicator
G021829
The tires have wear indicator strips running
across or parallel to the tread. The letters TWI
are printed on the side of the tire. When
approximately 1/16" (1.6 mm) is left on the
tread, these strips become visible and indicate
that the tire should be replaced. Tires with less
than 1/16" (1.6 mm) tread offer very poor trac-
tion.
When replacing worn tires, it is recommended
that the tire be identical in type (radial) and sizeas the one being replaced. Using a tire of the
same make (manufacturer) will prevent altera-
tion of the driving characteristics of the vehicle.
Improving tire economy
•Maintain correct tire pressure. See the tire
inflation table on page 299.
•Drive smoothly: avoid fast starts, hard
braking and tire screeching.
•Tire wear increases with speed.
•Correct front wheel alignment is very
important.
•Unbalanced wheels impair tire economy
and driving comfort.
•Tires must maintain the same direction of
rotation throughout their lifetime.
•When replacing tires, the tires with the
most tread should be mounted on the rear
wheels to reduce the chance of oversteer
during hard braking.
•Hitting curbs or potholes can damage the
tires and/or wheels permanently.
Summer and winter tires
G021778
The arrows shows the direction of rotation of the
tire
•When switching between summer and
winter tires, mark the tires to indicate
where they were mounted on the car, e.g.,
LF = left front, RR = right rear
•Tires with tread designed to roll in only one
direction are marked with an arrow on the
sidewall.
•Incorrectly mounted tires impair the car's
braking properties and ability to force
aside rain, snow and slush.
•The tires with the most tread should always
be at the rear (to reduce the risk of skid-
ding).
•Contact a Volvo workshop if you are
unsure about the tread depth.

G010753
Federal law mandates that tire manufacturers
place standardized information on the sidewall
of all tires (see the illustration).
The following information is listed on the tire
sidewall:
The tire designation:
NOTE
Please be aware that the following tire des-
ignation is an example only and that this
particular tire may not be available on your
vehicle.
1.
215: the width of the tire (in millimeters)
from sidewall edge to sidewall edge. The
larger the number, the wider the tire.
2.
65: The ratio of the tire's height to its width
in percent.
3.
R: Radial tire (the designation RF and the
symbol indicate that the vehicle is
equipped with optional self-supporting run
flat tires
1. See page 319 for more informa-
tion about these tires).
4.
15: The diameter of the wheel rim (in
inches).
5.
95: The tire's load index. In this example, a
load index of 95 equals a maximum load of
1521 lbs (690 kg).
6.
H: The tire's speed rating, or the maximum
speed at which the tire is designed to be
driven for extended periods of time, carry-
ing a permissible load for the vehicle, and
with correct inflation pressure. For exam-
ple, H indicates a speed rating of 130 mph
(210 km/h).
NOTE
The tire's load index and speed rating may
not appear on the sidewall because they are
not required by law.
7.
M+S or M/S = Mud and Snow, AT = All
Terrain, AS = All Season
8.
U.S. DOT Tire Identification Number
(TIN): This begins with the letters "DOT"
and indicates that the tire meets all federal
standards. The next two numbers or letters
are the plant code where it was manufac-
tured, the next two are the tire size code
and the last four numbers represent the
week and year the tire was built. For exam-
ple, 1510 means that the tire was manu-
factured during week 15 of 2010. The num-
bers in between are marketing codes used
at the manufacturer's discretion. This infor-
mation helps a tire manufacturer identify a
tire for safety recall purposes.
9.
Tire Ply Composition and Material
Used: Indicates the number of plies indi-
cates or the number of layers of rubber-
coated fabric in the tire tread and sidewall.
Tire manufacturers also must indicate the
ply materials in the tire and the sidewall,
which include steel, nylon, polyester, and
others.

7. Connect the electrical wire to the nearest
12-volt socket in the vehicle.
NOTE
Be sure that none of the other 12-volt sock-
ets is being used while the compressor is in
operation.
8. Start the vehicle’s engine.
WARNING
The vehicle´s engine should be running
when the tire sealing system is used to avoid
battery drain. Therefore, be sure the vehicle
is parked in a well ventilated place, or out-
doors, before using the system.
9. Start the tire sealing system’s compressor
by pressing the on/off switch to position I.
WARNING
•Never stand next to the tire being inflated
when the compressor is in operation.
•If cracks, bubbles, etc. form on the tire,
switch off the compressor immediately.
•If there is visible damage to the sidewall
or the rim, the tire cannot be repaired.
The vehicle should not be driven if this
occurs. Contact a towing service or
Volvo On Call Roadside Assistance if
applicable.
NOTE
The air pressure gauge will temporarily
show an increase in pressure to approxi-
mately 88 psi (6 bar) while the sealing com-
pound is being pumped into the tire. The
pressure should return to a normal level
after approximately 30 seconds.
10. Within seven minutes, inflate the tire to
between 22—44 psi (1.8—3.0 bar). Switch
off the compressor briefly to get a clear
reading from the pressure gauge.
CAUTION
The compressor should not be used for
more than 10 minutes at a time to avoid
overheating.
WARNING
If the pressure remains below 22 psi
(1.8 bar) after approximately seven minutes,
turn off the compressor. In this case, the
hole is too large to be sealed and the vehicle
should not be driven.
11. Switch off the compressor and disconnect
the electrical wire from the 12-volt socket.
12. Unscrew the hose from the tire’s inflation
valve and reinstall the valve cap.
13. 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.

313 Inflating tires
The tire sealing system can be used to inflate
the tires. To do so:
1. Park the car in a safe place.
2. The compressor should be switched off.
Ensure that the on/off switch is in position
0 (the 0 side of the switch should be
pressed down).
3. Take out the electrical wire and hose.
4. Remove the valve cap from the tire’s infla-
tion valve and screw the hose connector
onto the valve as tightly as possible by
hand.
5. Connect the electrical wire to the nearest
12-volt socket in the vehicle.
6. Start the vehicle’s engine.WARNING
•The vehicle’s engine should be running
when the tire sealing system is used to
avoid battery drain. Therefore, be sure
the vehicle is parked in a well ventilated
place, or outdoors, before using the sys-
tem. The parking brake should be
securely applied and the gear selector
should be in the P (park) position.
•Children should never be left unattended
in the vehicle when the engine is running.
7. Check the tire’s inflation pressure on the
gauge. Switch off the compressor briefly to
get a clear reading from the pressure
gauge.
8. Refer to the tire inflation table in this chap-
ter for the correct inflation pressure. If the
tire needs to be inflated, start the tire seal-
ing system’s compressor (press the on/off
switch to position I). 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.
9. Turn off the compressor (press the on/off
switch to position 0) when the correct infla-
tion pressure has been reached.
10. Unscrew the hose from the tire’s inflation
valve and reinstall the valve cap.
11. Disconnect the electrical wire from the
12-volt socket.

Self-supporting run flat tires (SST)*
Self-supporting run flat tires are available as
optional equipment. The vehicle must be
equipped with the Tire Pressure Monitoring
System (TPMS) if tires of this type are installed.
Tires of this type have specially reinforced
sidewalls that make it possible to continue
driving to a limited extent even though the tire
has lost some or all of its inflation pressure.
These tires are mounted on special rims (nor-
mal tires can also be mounted on these rims).
If an SST tire loses inflation pressure, the yel-
low TPMS symbol illuminates in the instrument
panel and a text message is also displayed. If
this happens, reduce speed to not more than
50 mph (80 km/h). The tire should be replaced
as soon as possible.
Drive carefully; it may be difficult to determine
which tire is damaged. To find the damaged
tire, check the inflation pressure in all four tires.
WARNING
•SST tires should only be mounted by
service technicians who are familiar
with tires of this type.
•SST tires may only be mounted on vehi-
cles equipped with TPMS.
•Do not drive faster than 50 mph
(80 km/h) if TPMS indicates that a tire
has lost inflation pressure.
•Do not drive farther than 50 miles
(80 km) before replacing a damaged
SST tire.
•Drive carefully and avoid e.g., hard
braking or fast turns.
•SST tires must be replaced if they are
damaged. A tire of this type cannot be
repaired.
