Introduction
Important warnings
13 Accessory Installation
•We strongly recommend that Volvo owners
install only genuine, Volvo-approved
accessories, and that accessory installa-
tions be performed only by a trained and
qualified Volvo service technician.
•Genuine Volvo accessories are tested to
ensure compatibility with the performance,
safety, and emission systems in your vehi-
cle. Additionally, a trained and qualified
Volvo service technician knows where
accessories may and may not be safely
installed in your Volvo. In all cases, please
consult a trained and qualified Volvo serv-
ice technician before installing any acces-
sory in or on your vehicle.
•Accessories that have not been approved
by Volvo may or may not be specifically
tested for compatibility with your vehicle.
Additionally, an inexperienced installer
may not be familiar with some of your vehi-
cle's systems.
•Any of your vehicle's performance and
safety systems could be adversely affec-
ted if you install accessories that Volvo has
not tested, or if you allow accessories to be
installed by someone unfamiliar with your
vehicle.
•Damage caused by unapproved or
improperly installed accessories may not
be covered by your new vehicle warranty.
See your Warranty and Service RecordsInformation booklet for more warranty
information. Volvo assumes no responsi-
bility for death, injury, or expenses that
may result from the installation of nonge-
nuine accessories.
Driver distraction
•Driver distraction results from driver activ-
ities that are not directly related to control-
ling the vehicle in the driving environment.
Your new Volvo is, or can be, equipped
with many feature-rich entertainment and
communication systems. These include
hands-free cellular telephones, navigation
systems, and multipurpose audio systems.
You may also own other portable elec-
tronic devices for your own convenience.
When used properly and safely, they enrich
the driving experience. Improperly used,
any of these could cause a distraction.
•For all of these systems, we want to pro-
vide the following warning that reflects the
strong Volvo concern for your safety:
•Never use these devices or any feature of
your vehicle in a way that distracts you
from the task of driving safely. Distraction
can lead to a serious accident. In addition
to this general warning, we offer the fol-
lowing guidance regarding specific newer
features that may be found in your vehicle:
•Never use a hand-held cellular telephone
while driving. Some jurisdictions prohibitcellular telephone use by a driver while the
vehicle is moving.
•If your vehicle is equipped with a naviga-
tion system, set and make changes to your
travel itinerary only with the vehicle parked.
•Never program your audio system while
the vehicle is moving. Program radio pre-
sets with the vehicle parked, and use your
programmed presets to make radio use
quicker and simpler.
•Never use portable computers or personal
digital assistants while the vehicle is mov-
ing.
A driver has a responsibility to do everything
possible to ensure his or her own safety and
the safety of passengers in the vehicle and oth-
ers sharing the roadway. Avoiding distractions
is part of that responsibility.

1. Malfunction indicator light
As you drive, a computer called
On-Board Diagnostics II (OBDII)
monitors your car's engine, trans-
mission, electrical and emission
systems.
The CHECK ENGINE light will light up if the
computer senses a condition that potentially
may need correcting. When this happens,
please have your car checked by a trained and
qualified Volvo service technician as soon as
possible.
A CHECK ENGINE light may have many cau-
ses. Sometimes, you may not notice a change
in your car's behavior. Even so, an uncorrected
condition could hurt fuel economy, emission
controls, and drivability. Extended driving with-
out correcting the cause could even damage
other components in your car.
NOTE
Canadian models are equipped with the
second symbol.
2. Anti-lock Brake system (ABS)If the warning light comes on, there
is a malfunction of the ABS system
(the standard braking system will
still function).
The vehicle should be driven to a
trained and qualified Volvo service
technician for inspection, see
page 150 for additional informa-
tion.
NOTE
Canadian models are equipped with the
second symbol.
3. Rear fog lightThis symbol indicates that the rear
fog light (located in the driver's

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.
G020349
Thumb wheel
RESET button
Spin control (SC)The spin control function is designed to help
prevent the drive wheels from spinning while
the vehicle is accelerating.
Under certain circumstances, such as when
driving with snow chains, or driving in deep
snow or loose sand, it may be advisable to
temporarily switch off this function for maxi-
mum tractive force.
Temporarily switching off Spin control1. Turn the thumbwheel (A) on the left-side
steering wheel lever until the DSTC menu
is displayed.
2.
Hold down the RESET button (B) to toggle
between
DSTC SPIN CONTROL ON orOFF.
NOTE
•The message DSTC SPIN CONTROL
OFF indicates that the stability sys-
tem's spin control function has tempo-
rarily 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.
•DSTC ON indicates that all system
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.

one of the following situations:
•The light illuminates for approximately
2 seconds to indicate that the system is
performing a self-diagnostic test when the
engine is started.
•If the light flashes while driving, this indi-
cates that the stability system is actively
functioning to help counteract wheel spin
and/or a skid.
•If this light stays on after the engine has
started or comes on while driving, there
may be a fault in the stability system. Con-
sult a trained and qualified Volvo service
technician.
•If Spin control has been intentionally
switched off, a message is displayed and

Uniform tire quality gradings
ALL PASSENGER VEHICLE TIRES MUST
CONFORM TO FEDERAL SAFETY
REQUIREMENTS IN ADDITION TO THESE
GRADES
Quality grades can be found, where appli-
cable, on the tire sidewall between the tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA
Temperature A
TREADWEARThe treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course. For example, a tire gra-
ded 150 would wear one and one half (1 1/2)
times as well on the government course as a
tire graded 100. The relative performance of
tires depends upon the actual conditions of
their use, however, and many depart signifi-
cantly from the norm due to variation in driving
habits, maintenance practices and differences
in road characteristics and climate.
TRACTIONThe traction grades, from highest to lowest, are
AA, A, B, and C, as measured under controlled
conditions on specified government test sur-faces of asphalt and concrete. A tire marked C
may have poor traction performance. The trac-
tion grade assigned to this tire is based on
braking (straight-ahead) traction tests and is
not a measure of cornering (turning) traction.
WARNING
The traction grade assigned to this tire is
based on braking (straight-ahead) traction
tests and is not a measure of cornering
(turning) traction.
TEMPERATUREThe temperature grades are AA (the highest),
A, B, and C, representing the tire's resistance
to the generation of heat and its ability to dis-
sipate heat when tested under controlled con-
ditions on a specified indoor laboratory test
wheel. Sustained high temperature can cause
the material of the tire to degenerate and
reduce tire life, and excessive temperature can
lead to sudden tire failure. The grade C corre-
sponds to a minimum level of performance that
all passenger vehicle tires must meet under the
Federal Motor Safety Standard No. 109.
Grades B and A represent higher levels of per-
formance on the laboratory test wheel than the
minimum required by law.
WARNING
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, under-
inflation, or excessive loading, either sepa-
rately or in combination, can cause heat
buildup and tire failure.
