NOTE
•When parking the vehicle with a trailer
on a hill, apply the parking brake before
putting the gear selector in P. Always
follow the trailer manufacturer's recom-
mendations for wheel chocking.
•When starting on a hill, put the gear
selector in D before releasing the park-
ing brake. See also page 118 for more
detailed information about starting off
on a hill while towing a trailer.
•If you use the manual (Geartronic) shift
positions while towing a trailer, make
sure the gear you select does not put
too much strain on the engine (using too
high a gear).
•The drawbar assembly/trailer hitch may
be rated for trailers heavier than the
vehicle is designed to tow. Please
adhere to Volvo's recommended trailer
weights.
•Avoid driving with a trailer on inclines of
more than 15 %.
Trailer cableAn adapter is required if the vehicle's trailer
hitch has a 13-pin connector and the trailer has
7 pins. Use an adapter cable approved by
Volvo. Make sure the cable does not drag on
the ground.

Towing eyelet
G021500
Attaching the towing eyelet
Attaching the towing eyeletThe towing eyelet is located under the floor
of the trunk, with the spare tire. This eyelet
must be screwed into the positions provi-
ded on the right sides of either the front or
rear bumper (see illustration).
There are two different types of covers over
the openings for the towing eyelet and they
have to be opened differently.
•If the cover has a notch, insert a coin,
etc., into the notch and pry open the
edge of the cover. Open the cover com-
pletely and remove it.
•If the cover has a mark along one edge
or in a corner, press the mark while pry-
ing out the opposite side/corner using a
coin, etc. Open the cover and remove it.
Screw the towing eyelet in place, first by hand
and then using the tire iron until it is securely in
place.
After the vehicle has been towed, the eyelet
should be removed and returned to its storage
location.
Press the cover for the attachment point back
into position.
NOTE
On certain models equipped with a trailer
hitch, the towing eyelet cannot be screwed
into the hole in the rear bumper. The towing
rope should be attached to the trailer hitch
instead. For this reason, the detachable
section of the trailer hitch should be safely
stowed in the vehicle at all times.
CAUTION
If the vehicle is being towed on a flat bed
truck, the towing eyelets must not be used
to pull the vehicle up onto the flat bed.
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.
Precautions when the vehicle is in tow
•Attach jumper cables (see page 110) to
provide current for releasing the optional
electric parking brake and to move the gear
selector from the P position.
•The gear selector must be in position 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).
•While the vehicle is being towed, try to
keep the tow rope taut at all times.
•The vehicle should only be towed in the
forward direction.
WARNING
The ignition key should always be fully
inserted in the ignition slot when the vehicle
is being towed to help prevent the steering
wheel from locking.
On vehicles with the optional keyless drive,
the remote key must be in the passenger
compartment and the driver's door must be
closed.
NOTE
During towing, ignition mode II should be
used so that the lighting can be switched on.
CAUTION
Vehicles with AWD (All Wheel Drive) with the
front wheels off the ground should not be
towed at speeds above 50 mph (70 km/h) or
for distances longer than 30 miles (50 km).
CAUTION
•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, do not
attempt to start the vehicle by pushing
or pulling it as this will damage the
three-way catalytic converter(s). The
engine must be jump started using an
auxiliary battery (see page 110).
•If the vehicle is being towed on a flat bed
truck, the towing eyelets must not be
used to pull the vehicle up onto the flat
bed or to secure the vehicle on the flat
bed. Consult the tow truck operator.
Towing vehicles with front wheel drive/
All Wheel Drive
Volvo recommends the use of flat bed equip-
ment.
•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 vehi-
cle with the front wheels on the ground,please refer to the towing information on
page 218.
CAUTION
•Sling-type equipment applied at the
front will damage radiator and air con-
ditioning lines.
•It is equally important not to use sling-
type equipment at the rear or apply lift-
ing equipment inside the rear wheels;
serious damage 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. Consult the tow truck operator.

WHEELS AND TIRES

Introduction
Your vehicle is equipped with tires according
to the vehicle's tire information placard on the
B-pillar (the structural member at the side of
the vehicle, at the rear of the driver's door
opening).
CAUTION
Some Volvo models are equipped with an
Ultra High Performance tire and wheel com-
bination designed to provide maximum dry
pavement performance with consideration
for hydroplaning resistance. They may be
more susceptible to road hazard damage
and, depending on driving conditions, may
achieve a tread life of less than 20,000 miles
(30,000 km). Even if this vehicle is equipped
with Volvo’s advanced AWD or DSTC sys-
tem, these tires are not designed for winter
driving, and should be replaced with winter
tires when weather conditions dictate.
The tires have good road holding characteris-
tics and offer good handling on dry and wet
surfaces. It should be noted however that the
tires have been developed to give these fea-
tures on snow/ice-free surfaces.
Most models are equipped with "all-season"
tires, which provide a somewhat higher degree
of road holding on slippery surfaces than tireswithout the "all-season" rating. However, for
optimum road holding on icy or snow-covered
roads, we recommend suitable winter tires on
all four wheels.
When replacing tires, be sure that the new tires
are the same size designation, type (radial) and
preferably from the same manufacturer, on all
four wheels. Otherwise there is a risk of altering
the car's roadholding and handling characte-
ristics.
New Tires
Remember that tires are perishable goods. As
of 2000, the manufacturing week and year
(Department of Transportation (DOT) stamp)
will be indicated with 4 digits (e.g., 1510 means
that the tire illustrated was manufactured dur-
ing week 15 of 2010).
Tire ageTires degrade over time, even when they are
not being used. It is recommended that tires
generally be replaced after 6 years of normal
service. Heat caused by hot climates, frequent
high loading conditions or Ultra Violet (U.V.)
exposure can accelerate the aging process.
The temporary spare
1 should also be replaced
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.
Improving tire economy
•Maintain correct tire pressure. See the tire
inflation tables beginning on page 227.
•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.
Storing wheels and tiresWhen storing complete wheels (tires mounted
on rims), they should be suspended off the
floor or placed on their sides on the floor.
Tires not mounted on rims should be stored on
their sides or standing upright, but should not
be suspended.
CAUTION
Tires should preferably be stored in a cool,
dry, dark place, and should never be stored
in close proximity to solvents, gasoline, oils,
etc.
WARNING
•The wheel and tire sizes for your Volvo
are specified to meet stringent stability
and handling requirements. Unap-
proved wheel/tire size combinations
can negatively affect your vehicle's sta-
bility and handling.
•Any damage caused by installation of
unapproved wheel/tire size combina-
tions will not be covered by your new
vehicle warranty. Volvo assumes no
responsibility for death, injury, or
expenses that may result from such
installations.
Tire wear
Tire rotationTire wear is affected by a number of factors
such as tire inflation, ambient temperature,
driving style, etc. Your vehicle is driven mainly
by the front tires, which will wear faster.
If the tires are rotated, they should only be
moved from front to back or vice versa. They
should never be rotated left to right/right to left.
However, tire rotation, done at the recom-
mended intervals, is one way of helping to keep
tread wear as even as possible and will help
you get maximum mileage from your tires.

Ideally, tire rotation should be done the first
time after approximately 3,000 miles
(5, 000 km) and thereafter at 6,000 mile
(10,000 km) intervals.
Tire rotation should only be performed if front/
rear tire wear is fairly even and tread height is
above 1/16" (1.6 mm).
NOTE
Tire rotation is not included in regularly
scheduled maintenance and is performed
only at customer request, at additional
charge.
Your Volvo retailer can also provide guidance
based on your particular driving circumstan-
ces.
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 size
as the one being replaced. Using a tire of the
same make (manufacturer) will prevent altera-
tion of the driving characteristics of the vehicle.
