Introduction
General information
Shiftlock
When your car is parked, the gear selector is locked in the (P)ark position. To release the selector from this position,
turn the ignition key to position II (or start the engine), depress the brake pedal, press the button on the front side of the
gear selector and move the selector from (P)ark.
Keylock
When the ignition is switched off, the gear selector must be in the (P)ark position before the key can be removed from
the ignition switch.
Anti-lock Brake System (ABS)
The ABS system in your car performs a self -diagnostic test when the vehicle first reaches the speed of approximately
12 mph (20 km/h). The brake pedal will pulsate several times and a sound may be audible from the ABS control
module. This is normal.
Fuel filler door
Press the button on the light switch panel when the car is at a standstill to unlock the fuel filler door.
Fuel filler cap
After refueling, close the fuel filler cap by turning it clockwise until it clicks into place. If this cap is not closed tightly
or if the engine is running when the car is refueled, the Malfunction Indicator Lamp ("Check Engine" light) may
indicate a fault.
Points to keep in mind

The seat belt reminder reacts if the driver and/or the front seat passenger have not fastened their seat belts.
The indicator light above the mirror and the symbol in the instrument panel will light up and stay lit until the seat
belt(s) have been fastened, or until the remaining 5 minutes of the 6-minute cycle have elapsed.
The chime will sound for 6 seconds, at 30-second intervals. The frequency of the chiming increases with the speed
of the car.
After 6 minutes, the chime will no longer sound and the indicator lights will go out.
Seat belt maintenance
Check periodically that the seat belts are in good condition. Use water and a mild detergent for cleaning. Check seat
belt mechanism function as follows: attach the seat belt and pull rapidly on the strap.
pg. 14 Supplemental Restraint System (SRS)
Supplemental Restraint System
As an enhancement to the three-point seat belts, your Volvo is equipped with a Supplemental Restraint System (SRS).
Volvo's SRS consists of seat belt tensioners, front airbags, side impact airbags, the occupant weight sensor, and
inflatable curtains. All of these systems are monitored by the SRS control module. An SRS warning light in the
instrument panel (see the illustration above) illuminates when the ignition key is turned to position I, II, or III, and will
normally go out after approximately 7 seconds if no faults are detected in the system.
Where applicable, a text message will also be displayed when the SRS warning light illuminates.
If this warning symbol is not functioning properly, the general warning symbol
illuminates and a text message
will be displayed.
WARNING!
If the SRS warning light stays on after the engine has started or if it illuminates while you are driving, have the
vehicle inspected by a trained and qualified Volvo service technician as soon as possible.
Never try to repair any component or part of the SRS yourself. Any interference in the system could cause
malfunction and serious injury. All work on these systems should be performed by a trained and qualified Volvo
service technician.
WARNING!
If your vehicle has been subjected to flood conditions (e.g. soaked carpeting/ standing water on the floor of the
vehicle) or if your vehicle has become flood damaged in any way, do not attempt to start the vehicle or put the key
in the ignition before disconnecting the battery (see below). This may cause airbag deployment which could result in
personal injury. Have the vehicle towed to a trained and qualified Volvo service technician for repairs.

14. Temperature gauge
The gauge indicates the temperature of the engine cooling system. If the temperature is abnormally high and the needle
enters the red zone, a message is shown in the display. Bear in mind that auxiliary lamps in front of the air intake
reduce the cooling capacity at high outside temperatures and high engine loads.
15. Indicator and warning symbols
1. Models with All Wheel Drive have a tank volume of 15 US gallons (57 liters).
Models with engine code 39 have a fuel tank capacity of 14 US gallons (53 liters). This code is the 6th and 7th digits
from the left in your vehicle's VIN number. See page 176
for the location of the VIN plate.
pg. 35 Indicator and warning symbols
Function check
The indicator and warning symbols light up when you turn the ignition key to the driving position (position II) before
starting. This shows that the symbols are functioning. When the engine starts, all symbols go out. If the engine is not
started within 5 seconds, all of the symbols except CHECK ENGINE and
will go out. Certain symbols may not
have their functions illustrated, depending on the car's equipment. The PARK BRAKE symbol will not go out until the
parking brake has been released.
Symbols in the center of the instrument panel
Warning symbol
The red warning symbol lights up to indicate a fault that could affect the car's driveability. A text explaining the nature
of the fault will also be shown in the information display. The symbol and accompanying text will remain on until the
fault has been corrected. This symbol may also light up in combination with other indicator or warning symbols.
If the red warning symbol lights up:
1. Stop the car as soon as possible in a suitable location.
2. Read the message in the information display.
3. Follow the instructions provided, or contact a trained and qualified Volvo service technician.

1. Malfunction indicator light
As you drive, a computer called On-Board Diagnostics II (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 trained and qualified Volvo
service technician 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 controls, and driveability. Extended driving
without correcting the cause could even damage other components in your car.
Canadian models are equipped with this 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
107 for additional information. Canadian models are equipped with this symbol .
3. Rear fog light
This symbol indicates that the rear fog light (located in the driver's side tail light cluster) is on.

the front seats.
Canadian models are equipped with this symbol
.
3. SRS warning light
If this light comes on while the car is being driven, or remains on for longer than approximately 10 seconds
after the car has been started, the SRS system's diagnostic functions have detected a fault in a seat belt lock or
tensioner, 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.
4. Oil pressure warning light
If the light comes on while driving, stop the car, stop the engine immediately, and check the engine oil level.
If the oil level is normal and the light stays on after restart, have the car towed to the nearest trained and qualified
Volvo service technician. 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.
5. Seat belt reminder This symbol (and the seat belt reminder light above the rear view mirror) will light up if either front seat

Volvo service technician.
7. Brake failure warning light
If this light comes on while driving or braking, stop the car as quickly as possible in a safe place, open the
hood, and check the brake fluid level in the reservoir. See page 145
for the location of the reservoir.
pg. 38 Symbols on the right side of the instrument panel
Canadian models are equipped with this symbol .
WARNING!
If the fluid level is below the MIN mark in the reservoir or if a "Brake failure - Service urgent" message is displayed
in the information display: DO NOT DRIVE. Have the car towed to a trained and qualified Volvo service technician
and have the brake system inspected.
If the BRAKE and ABS warning lights come on at the same time, this could indicate a fault in the brake system.
In this case:
1. Stop the car in a suitable place and switch off the engine.
2. Restart the engine.
3. If both warning lights go off, no further action is required and the car can be driven.
4. If both lights remain on after the engine has been restarted, switch off the engine again and check the brake fluid
level. See page 145
for the location of the reservoir.
Door open warning
The driver will be alerted if one of the doors, the hood, or the trunk lid are open or ajar.
At low speeds
If the car is moving at a speed of less than approximately 4 m.p.h. (7 km/h), the Information symbol in the
instrument panel will light up and a message will be shown in the information display indicating which door(s), etc is
not completely closed.
At higher speeds
If the car is moving at a speed above approximately 4 m.p.h. (7 km/h), the Warning symbol in the
instrument panel will light up and a message will be shown in the information display indicating which door(s), etc is
not completely closed.
Hood and trunk If the hood and/or trunk lid is not completely closed, the Information symbol in the instrument panel will

pedal for the first few minutes of operation. A cold engine uses more fuel and is subject to increased wear.
Whenever possible, avoid using the vehicle for driving short distances. This does not allow the engine to reach
normal operating temperature.
Drive carefully and avoid rapid acceleration and hard braking.
Use the transmission's (D)rive position as often as possible and avoid using kickdown.
Do not exceed posted speed limits.
Avoid carrying unnecessary items (extra load) in the vehicle.
Maintain correct tire pressure. Check tire pressure regularly (when tires are cold).
Remove snow tires when threat of snow or ice has ended.
Note that roof racks, ski racks, etc, increase air resistance and also fuel consumption.
At highway driving speeds, fuel consumption will be lower with the air conditioning on and the windows closed
than with the air conditioning off and the windows open.
Using the onboard trip computer's fuel consumption modes can help you learn how to drive more economically.
Other factors that decrease gas mileage are:
Dirty air cleaner
Dirty engine oil and clogged oil filter
Dragging brakes
Incorrect front end alignment
Some of the above mentioned items and others are checked at the standard maintenance intervals.
Weight distribution affects handling
At the specified curb weight your vehicle has a tendency to understeer, which means that the steering wheel has to be
turned more than might seem appropriate for the curvature of a bend. This ensures good stability and reduces the risk
of rear wheel skid. Remember that these properties can alter with the vehicle load. The heavier the load in the cargo
area, the less the tendency to understeer.
WARNING!
Driving with the trunk open: Driving with the trunk open could lead to poisonous exhaust gases entering the
passenger compartment. If the trunk must be kept open for any reason, proceed as follows:
Close the windows
Set the ventilation system control to air flow to floor, windshield and side windows and the blower control to its
highest setting.
CAUTION!
Drive slowly and carefully if going through standing water (i.e. flooded roadways, etc.). Damage to the engine could
result if excess water is drawn in through the air intake system. Never drive the vehicle in water deeper than 18
inches (48 cm).
pg. 93 General information
Handling, roadholding
Vehicle load, tire design and inflation pressure all affect vehicle handling. Therefore, check that the tires are inflated to
the recommended pressure according to the vehicle load. See the "Tire pressure" section. Loads should be distributed
so that capacity weight or maximum permissible axle loads are not exceeded.
Cold weather precautions
If you wish to check your vehicle before the approach of cold weather, the following advice is worth noting:
Make sure that the engine coolant contains 50 percent antifreeze. Any other mixture will reduce freeze protection.
This gives protection against freezing down to -31°F (-35°C). See section "Coolant". The use of "recycled" antifreeze
