pg. 18 Warning lights
The warning lights described on pages 18 and 19 should never stay on when driving
When the ignition key is turned on and before the engine starts, all of the warning lights should go on to test the
function of the bulbs. Should a light not go off after the engine has started, the system indicated should be inspected.
However, the parking brake reminder light will not go off until the parking brake has been fully released.
Malfunction indicator lamp
On-Board Diagnostic II (OBDII): As you drive, a computer called "OBDII" monitors your car's engine, transmission,
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 Volvo retailer as soon as
possible.
A 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 cleanliness, and driveability. Extended driving
without correcting the cause could even damage other components in your car.
NOTE : If the fuel filler cap is not closed tightly or if the engine is running when the car is refueled, the Malfunction
Indicator Lamp may indicate a fault. However, your vehicle's performance will not be affected. Use only Volvo
original or approved fuel filler caps.
Canadian models are equipped with this warning light:
Oil pressure warning light
If the light comes on while driving, stop the car and then stop the engine immediately and check the engine oil
level . See page 116.
If the light stays on after restart, have the car towed to the nearest authorized Volvo retailer. After
hard driving, the light may come on occasionally when the engine is idling. This is normal, provided it goes off when
the engine speed is increased.
Roll Over Protection System (ROPS)
If the warning lamp remains on after the engine has started or comes on while you are driving, the ROPS self -
diagnostic system has detected a fault. The car should be driven to an authorized Volvo retailer as soon as possible for
inspection.
Please refer to page 10
for more information on the ROPS system.
Brake failure warning light
If the light comes on while driving or braking, stop immediately, open the hood and check the brake fluid level

in the reservoir. See page 118 for reservoir position.
Canadian models are equipped with this warning light:
WARNING!
If the fluid level is below the MIN mark in either section of the reservoir: DO NOT DRIVE. Tow the car to a Volvo
retailer and have the brake system checked and any leakage repaired.
Parking brake reminder light
This light will be on when the parking brake (hand brake) is applied. The parking brake lever is situated between the
front seats.
Canadian models are equipped with this warning light:
pg. 19 Warning lights
STC disengaged
The indicator light (
) in the instrument panel will be ON when you have switched the Stability and Traction Control
system (STC) OFF using the button on the dashboard (see page 23
). The light will also come on if there is a fault in the
STC system or to indicate that the brakes have overheated. The light will go out when the brake temperature returns to
normal.
The
symbol will flash when STC is actively regulating power to the drive wheels. Normal power may be reduced at
this time. This is normal as power is momentarily reduced to help keep the drive wheels from losing traction and
spinning.
Anti-lock Brake system (ABS)
If the warning lamp lights up there is a malfunction of the ABS system (the standard braking system will however
function). The vehicle should be driven to a Volvo retailer for inspection.
See page 74
for additional information.
Canadian models are equipped with this warning light:
Coolant level sensor
If this light comes on while driving, the coolant level is low. The coolant level in the expansion tank should be
checked immediately and topped up if necessary. The cooling system should be inspected by an authorized Volvo
retailer.
Mode "W" engaged
The lamp will light up when the Winter/Wet starting mode is engaged or if gears "3" or "L" are selected.
If the warning lamp begins to flash , this means that there is a fault in the automatic gearbox. Contact Your Volvo
retailer.
Supplemental Restraint System (SRS)
If the light comes on (or stays on after the vehicle has started), the SRS diagnostic system has detected a fault. Drive to
an authorized Volvo retailer for an inspection of the system. See the SRS section for more information.
Generator warning light
If the light comes on while the engine is running, have the charging system checked.

Do not load your car beyond the load limits indicated.
*Please note that the tire information label indicates pressure for both comfort and fuel economy.

Uniform tire quality grading
ALL PASSENGER CAR TIRES MUST CONFORM TO FEDERAL SAFETY REQUIREMENTS IN
ADDITION TO THESE GRADES
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,
service 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.WARNING!
The traction grade assigned to this tire is based on braking (straight-ahead) traction tests and does not include
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

Accessory Installation - Important Warning
We strongly recommend that Volvo owners install only genuine, Volvo-approved accessories, and that accessory
installations be performed only by the factory-trained technicians at your authorized Volvo retailer.
Genuine Volvo accessories are tested to ensure compatibility with the performance, safety, and emission systems in
your car. Additionally, your authorized Volvo retailer knows where accessories may and may not be safely installed in
your Volvo. In all cases, please consult your authorized Volvo retailer before installing any accessory in or on your
car.
Accessories that have not been approved by Volvo may or may not be specifically tested for compatibility with your
car. 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 tested, or if you allow accessories to be installed by someone unfamiliar with your car.
Damage caused by unapproved or improperly installed accessories may not be covered by your new car warranty.
See your Warranty and Service Records Information booklet for more warranty information. Volvo assumes no
responsibility for death, injury, or expenses that may result from the installation of non-genuine accessories.
Driver Distraction
Driver distraction results from driver activities that are not directly related to controlling the car 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
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 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 following guidance regarding specific newer features that may be
found in your vehicles:
Never use a hand -held cellular telephone while driving. Some jurisdictions prohibit cellular telephone use by a
driver while the vehicle is moving.
If your car is equipped with a navigation 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 presets 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 moving.
