between approximately 45-55 mph (70-90 km/
h).
Swaying may be caused by factors such as:
•The vehicle and trailer are hit by a sudden,
strong crosswind
•The vehicle and trailer are traveling on an
uneven road surface or drive over a bump
•Sudden movements of the steering wheel
Facts about TSA
•TSA intervenes at speeds above approxi-
mately 40 mph (60 km/h)
•The DSTC symbol () in the instru-
ment panel will flash when TSA is working
•If the driver switches off the DSTC sys-
tem's Spin Control function, TSA will also
be switched off (but will be on again the
next time the engine is started)
•TSA may not intervene when the vehicle
and trailer begin to sway if the driver tries
to compensate for the swaying motion by
moving the steering wheel rapidly
How TSA worksOnce swaying has begun, it can be very diffi-
cult to stop, which makes it difficult to control
the vehicle and trailer.
The TSA system continuously monitors the
vehicle's movements, particularly lateralmovement. If the system detects a tendency to
sway, the brakes are applied individually on the
front wheels, which has a stabilizing effect on
the vehicle and trailer. This is often enough to
enable the driver to regain control of the vehi-
cle.
If this is not adequate to stop the swaying
motion, the brakes are applied to all of the
wheels on the vehicle and on the trailer if it is
equipped with brakes, and engine power is
temporarily reduced. As the swaying motion
begins to decrease and the vehicle-trailer have
once again become stable, TSA will no stop
regulating the brakes/engine power and the
driver regains control of the vehicle.

Towing eyelet
G017464
Location of the towing eyelet
Attaching the towing eyelet
Attaching the towing eyeletThe towing eyelet is located under the floor
of the cargo area, with the spare tire. This
eyelet must be screwed into the positionsprovided 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.

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.

Having the vehicle towed by a tow
truck
Call for professional help from an authorized
towing company.Volvo recommends the use of
flat bed equipment.
CAUTION
•The vehicle should always be towed in
the forward direction.
•Vehicles with All Wheel Drive (AWD)*
that are being towed with the front
wheels off the ground should not be
towed at a speed above approx. 45 mph
(70 km/h) and should not be towed far-
ther than 30 miles (50 km).
•If the vehicle is being towed on a flat bed
truck, the towing eyelet 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.

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 rotationYour vehicle has no required tire rotation. Tire
wear is affected by a number of factors such
as tire inflation, ambient temperature, driving
style, etc.
NOTE
•If the tires are rotated, they should only
be moved from front to rear or vice
versa. They should never be rotated left
to right/right to left.
•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. Some
customers find that tire rotation may
help to get extra mileage from tire life.
•Tire rotation should only be performed
if front/rear tire wear is fairly even and
tread height is above 1/16" (1.6 mm).
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
