Important warnings
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 others 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 feature-rich entertainment and communication
systems. These include hands-free cellular telephones, navigation systems, and multipurpose audio systems. You may
also own other portable electronic devices for your own convenience. When used properly and safely, they enrich the

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 hurt fuel economy, emission controls, and drivability.
Extended driving without correcting the cause could even damage other components in your vehicle.

All Wheel Drive - AWD
2
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 conditions, most of the engine's power is directed to the front
wheels. However, if there is any tendency for the front wheels to spin, an electronically controlled coupling distributes
power to the wheels that have the best traction.
1If the battery is dead, the optional electric parking brake cannot be applied or released. Connect an auxiliary battery if the battery voltage is too
low, see page 104
.
2Standard on certain models.
107 03 Your driving environment
Brakes
Brake system
The brake system is a hydraulic system consisting of two separate brake circuits. If a problem should occur in one of
these circuits, it is still possible to stop the vehicle with the other brake circuit.
If the brake pedal must be depressed farther than normal and requires greater foot pressure, the stopping distance will
be longer.
A warning light in the instrument panel will light up to warn the driver that a fault has occurred.
If this light comes on while driving or braking, stop immediately and check the brake fluid level in the reservoir.
NOTE
Press the brake pedal hard and maintain pressure on the pedal - do not pump the brakes.
WARNING
If the fluid level is below the MIN mark in the reservoir or if a brake system message is shown in the information
display: DO NOT DRIVE. Have the vehicle towed to a trained and qualified Volvo service technician and have the
brake system inspected.
Power brakes function only when the engine is running
The power brakes utilize vacuum pressure which is only created when the engine is running. Never let the vehicle roll
to a stop with the engine switched off.
If the power brakes are not working, the brake pedal must be pressed approximately five times harder than usual to
make up for the lack of power assistance. This can happen for example when towing your vehicle or if the engine is
switched off when the vehicle is rolling. The brake pedal feels harder than usual.

139 04 Comfort and driving pleasure
Stability system
Introduction
The Dynamic Stability and Traction Control system (DSTC) consists of a number of functions designed help reduce
wheel spin, counteract 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 stability, 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 maximum tractive force.
WARNING
The car's handling and stability characteristics will be altered if the spin control function has been disabled.
Operation
Temporarily switching off Spin control
1. Turn the thumbwheel
until the DSTC menu is shown.

NOTE
The red warning light may be difficult to see in strong sunlight or when sunglasses are being worn.
WARNING
Cruise control only warns of vehicles detected by the radar sensor, see page 146
. In some cases there may be no
warning or the warning may be delayed. The driver should always apply the brakes when necessary.
Automatic deactivation
Adaptive cruise control is linked to other systems such as the stability and traction control system (DSTC). If any of
these systems are not functioning 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
146 04 Comfort and driving pleasure
Adaptive Cruise Control-ACC
driver must 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 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 limitations
The radar sensor is used both by the adaptive cruise control and the collision warning system. It is designed to detect
vehicles or larger vehicles driving in the same direction as your vehicle. The radar sensor does not detect pedestrians,
or oncoming, slow or stationary vehicles and objects. Warnings are not given and the brakes are not applied in such
cases.
WARNING
Accessories or other objects 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:
if the radar sensor is obstructed and cannot detect other vehicles, for example in heavy rain, or if snow or other
objects are obscuring the radar sensor.
NOTE
Keep the area in front of the radar sensor clean.

ALL PASSENGER VEHICLE TIRES MUST CONFORM TO FEDERAL SAFETY REQUIREMENTS IN
ADDITION TO THESE GRADES
Quality grades can be found, where applicable, on the tire sidewall between the tread shoulder and maximum
section width. For example:
Treadwear 200 Traction AA Temperature A TREADWEAR
The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions
on a specified government test course. For example, a tire graded 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 significantly from the norm due to variation in driving habits,
maintenance practices and differences in road characteristics and climate.
TRACTION
The traction grades, from highest to lowest, are AA, A, B, and C, as measured under controlled conditions on specified
government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. The traction
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.
TEMPERATURE
The temperature grades are AA (the highest), A, B, and C, representing the tire's resistance to the generation of heat
and its ability to dissipate heat when tested under controlled conditions 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 corresponds 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 performance on the laboratory test wheel than the minimum required by law.
WARNING
The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive
speed, under-inflation, or excessive loading, either separately or in combination, can cause heat buildup and tire
failure.
231 06 Maintenance and specifications
Wheels and tires
Snow chains, snow tires, studded tires
Snow chains
Snow chains can be used on your Volvo with the following restrictions:
Snow chains should be installed on front wheels only. Use only Volvo approved snow chains.
If accessory, aftermarket or "custom" tires and wheels are installed and are of a size different than the original tires
and wheels, chains in some cases CANNOT be used. Sufficient clearances between chains and brakes, suspension and
body components must be maintained.
