in our plants 50% since 1991.
Volvo was the first in the world to introduce into production a three-way catalytic converter with a Lambda sond, now
called the heated oxygen sensor, in 1976. The current version of this highly efficient system reduces emissions of
harmful substances (CO, HC, NOx) from the exhaust pipe by approximately 95-99% and the search to eliminate the
remaining emissions continues. Volvo is the only automobile manufacturer to offer CFC-free retrofit kits for the air
conditioning system of all models as far back as the 1975 model 240. Advanced electronic engine controls and cleaner
fuels are bringing us closer to our goal. After Volvo vehicles and parts have fulfilled their use, recycling is the next
critical step in completing the life cycle. The metal content is about 75% of the total weight of a vehicle, which makes
the vehicle among the most recycled industrial products. In order to have efficient and well-controlled recycling,
dismantling information is available for all Volvo models. For Volvo, all homogeneous plastic parts weighing more
than 3.4 oz. (100 grams) are marked with international symbols that indicate how the component is to be sorted for
recycling. In addition to continuous environmental refinement of conventional gasoline-powered internal combustion
engines, Volvo is actively looking at advanced technology alternative-fuel vehicles.
When you drive a Volvo, you become our partner in the work to lessen the car's impact on the environment. To reduce
your vehicle's environmental impact, you can:
Maintain proper air pressure in your tires. Tests have shown decreased fuel economy with improperly inflated tires.
Follow the recommended maintenance schedule in your Warranty and Service Records Information booklet.
Drive at a constant speed whenever possible.
See a trained and qualified Volvo service technician as soon as possible for inspection if the check engine (
malfunction indicator) light illuminates, or stays on after the vehicle has started.
Properly dispose of any vehicle-related waste such as used motor oil, used batteries, brake pads, etc.
When cleaning your vehicle, please use genuine Volvo car care products. All Volvo car care products are
formulated to be environmentally friendly.

symbol for faults in the vehicle's emissions system and the symbol for low oil pressure.
Certain symbols may not have their functions illustrated, depending on the vehicle's equipment.
Indicator and warning symbols
Trailer turn signal indicator
If you are towing a trailer, this light will flash simultaneously with the trailer's turn signals. If the light does not flash,
or if they flash faster than usual when signaling a turn, the turn signals on the trailer or on the vehicle are not
functioning properly.
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 service
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.
Canadian models are equipped with this symbol:

equipped with the electric parking brake, this symbol flashes while the brake is being applied and then glows steadily.
A flashing symbol means that a fault has been detected. See the message in the information display.
Canadian models are equipped with this symbol:
NOTE

This symbol also comes on when the mechanical parking brake is only slightly applied.
Airbags - SRS
If this light comes on while the vehicle is being driven, or remains on for longer than approximately 10 seconds after
the vehicle has been started, the SRS system's diagnostic functions have detected a fault in a seat belt lock or
pretensioner, a front airbag, side impact airbag, and/or an inflatable curtain. Have the system(s) inspected by a trained
and qualified Volvo service technician as soon as possible.
Seat belt reminder
This symbol comes on for approximately 6 seconds if the driver has not fastened his or her seat belt.
Generator not charging
This symbol comes on during driving if a fault has occurred in the electrical system. Contact an authorized Volvo
workshop.
Engine temperature
Engine overheating can result from low oil or coolant levels, towing or hard driving at high heat and altitude, or
mechanical malfunction. Engine overheating will be signaled with text and a red warning triangle in the middle of the
instrument display. The exact text will depend on the degree of overheating. It may range from " HIGH ENGINE
TEMP - SLOW DOWN " to "HIGH ENGINE TEMP - STOP ENGINE ." If appropriate, other messages, such as
" COOLANT LEVEL LOW " will also be displayed. If your engine does overheat so that you must stop the engine,
always allow the engine to cool before attempting to check oil and coolant levels.
Fault in brake system
If this symbol lights, the brake fluid level may be too low. Stop the vehicle in a safe place and check the level in the
brake fluid reservoir, see page 211
. If the level in the reservoir is below MIN , the vehicle should be transported to an
authorized Volvo workshop to have the brake system checked.
If the brake and ABS symbols come on at the same time, there may be a fault in the brake force distribution system.
1. Stop the vehicle in a safe place and turn off the engine.
2. Restart the engine.
If both symbols extinguish, continue driving.
If the symbols remain on, check the level in the brake fluid reservoir. See page 211. If the brake fluid level is
normal but the symbols are still lit, the vehicle can be driven, with great care, to an authorized Volvo workshop to
have the brake system checked.
If the level in the reservoir is below MIN , the vehicle should be transported to an authorized Volvo workshop to
have the brake system checked.
WARNING
If the fluid level is below the MIN mark in the reservoir or if a warning message is displayed in the text window:
DO NOT DRIVE. Have the vehicle towed to a trained and qualified Volvo service technician and have the brake
system inspected.
If the ABS and Brake system lights are on at the same time, there is a risk of reduced vehicle stability.

112 03 Your driving environment
Transmission
All Wheel Drive - AWD1
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.
1Standard on certain models.
113 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.
