Important warnings
9 Driver distraction
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.
Driver distraction results from driver activities
that are not directly related to controlling the
vehicle in the driving environment. Your new
Volvo is, or can be, equipped with many fea-
ture-rich entertainment and communication
systems. These include hands-free cellular tel-
ephones, navigation systems, and multipur-
pose audio systems. You may also own other
portable electronic devices for your own con-
venience. 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 provide the
following warning that reflects the strong Volvo
concern for your safety.Never use these devi-
ces 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
following 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.
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 car's
systems.
•
Any of your car's performance and safety
systems could be adversely affected if you
install accessories that Volvo has not tes-
ted, or if you allow accessories to be instal-
led by someone unfamiliar with your vehi-
cle.
•
Damage caused by unapproved or
improperly installed accessories may not
be covered by your new vehicle warranty.
See your Warranty and Service Records
Information booklet for more warranty
information. Volvo assumes no responsi-
bility for death, injury, or expenses that
may result from the installation of non-gen-
uine accessories.

Malfunction Indicator Light
As you drive, a computer called On-Board
Diagnostics II (OBDII) monitors your vehicle's
engine, transmission, electrical and emission
systems.
The malfunction indicator (CHECK ENGINE)
light will illuminate if the computer senses a
condition that potentially may need correcting.
When this happens, please have your vehicle
checked by a trained and qualified Volvo serv-
ice technician as soon as possible.
A malfunction indicator (CHECK ENGINE) light
may have many causes. Sometimes, you may
not notice a change in your car's behavior.
Even so, an uncorrected condition could hurtfuel economy, emission controls, and drivabil-
ity. Extended driving without correcting the
cause could even damage other components
in your vehicle.
This light may illuminate if the fuel filler cap is
not closed tightly or if the engine was running
while the vehicle was refueled.

All Wheel Drive – AWD
4
Your Volvo can be equipped with permanent
All Wheel Drive, which means that power is
distributed automatically between the front
and rear wheels. Under normal driving condi-
tions, most of the engine's power is directed to
the front wheels. However, if there is any ten-
dency for the front wheels to spin, an electron-
ically controlled coupling distributes power to
the wheels that have the best traction.
NOTE
The message
AWD disabled Service
required
will be appear in the information
display if an electrical fault should occur in
the AWD system. A warning light will also
illuminate in the instrument panel. If this
occurs, have the system checked by a
trained and qualified Volvo service techni-
cian.

Stability system
04``155 Introduction
The Dynamic Stability and Traction Control
system (DSTC) consists of a number of func-
tions designed help reduce wheel spin, coun-
teract skidding, and to generally help improve
directional stability.
CAUTION
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 DSTC's permanent functions and
cannot be switched off.Active Yaw Control (AYC)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.
This is one of DSTC's permanent functions and
cannot be switched off.
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.
WARNING
The car's handling and stability characteris-
tics will be altered if the spin control function
has been disabled.Operation

Adaptive Cruise Control–ACC (option)
04``169
WARNING
•
Only use a time interval that is suitable
in current traffic conditions.
•
A short time interval gives the driver lim-
ited reaction time if an unexpected sit-
uation occurs in traffic.
The number of bars indicating the selected
time interval are shown while the setting is
being made and for several seconds afterward.
A smaller version of the symbol is then shown
to the right in the display. The same symbol is
also displayed when Distance Alert is acti-
vated, see page 173 .Deactivating and resuming settingsCruise control is deactivated, either with a
short press on
, or by action taken by the
driver, such as braking, etc. The set speed, for
example 55 mph, is then shown in parenthe-
ses. Speed and time interval are resumed by
pressing
.
WARNING
There may be a significant increase in speed
after the
button has been pressed.
A short press on
in standby mode or a long
press in active mode deactivates cruise con-trol. The set speed is then cleared and cannot
be resumed.
When ACC is activated, the vehicle’s speed
increases by approximately 1 mph (1 km/h)
each additional time
is pressed.
Deactivation due to action by the driverACC is deactivated:•
when the brakes are applied
•
if the gear selector is moved to N
•
if the accelerator pedal is depressed for an
extended period.NOTE
If the accelerator pedal is only depressed for
a short time, such as when passing another
vehicle, ACC is deactivated temporarily and
is reactivated when the pedal is released.Automatic deactivationAdaptive cruise control is linked to other sys-
tems such as ABS, the stability and traction
control system (DSTC), and the Distance Alert
System. If any of these systems are not func-
tioning properly, adaptive cruise control is
automatically deactivated.
In the event of automatic deactivation a signal
will sound and the message
Cruise Control
Canceled
is shown in the display. The drivermust then intervene and adapt the vehicle's
speed to the surrounding traffic.
Automatic deactivation may be caused if:
•
the vehicle's speed falls below 20 mph
(30 km/h)
•
the wheels lose traction or if the anti-lock
brake system (ABS) is activated
•
brake temperature is high
•
engine speed (rpm) is too low
•
the radar sensor is obstructed by, for
example, wet snow or rain.
The radar sensor and its limitationsThe radar sensor is used by both Adaptive
Cruise Control and the Collision Warning Sys-
tem with Auto-brake. It is designed to detect
cars or larger vehicles driving in the same
direction as your vehicle.
WARNING
Accessories or other objects, such as extra
headlights, must not be installed in front of
the grille.
Modification of the radar sensor could make
its use illegal.The radar sensor's capacity to detect vehicles
ahead is impeded:

4. The resulting figure equals the available
amount of cargo and luggage load
capacity. For example, if the "XXX" amount
equals 1400 lbs. and there will be five
150 lb. passengers in your vehicle, the
amount of available cargo and luggage
load capacity is 650 lbs. (1400 – 750
(5 × 150) = 650 lbs.)
5. Determine the combined weight of luggage
and cargo being loaded on the vehicle.
That weight may not safely exceed the
available cargo and luggage load capacity
calculated in Step 4.
6. If your vehicle will be towing a trailer, load
from your trailer will be transferred to your
vehicle. Consult this manual
1 to determine
how this reduces the available cargo and
luggage load capacity of your vehicle.
WARNING
•
Exceeding the permissible axle weight,
gross vehicle weight, or any other
weight rating limits can cause tire over-
heating resulting in permanent defor-
mation or catastrophic failure.
•
Do not use replacement tires with lower
load carrying capacities than the tires
that were original equipment on the
vehicle because this will lower the vehi-
cle's GVW rating. Replacement tires
with a higher limit than the originals do
not increase the vehicle's GVW rating
limitations.
Uniform Tire Quality GradingALL 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.
