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 123
. 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.

Generator warning light
If the light comes on while the engine is running, have the charging system checked.
* Rear fog light, if used, and trailer turn signal, if towing a trailer, will go on while driving.

CHECK
ENGINE
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.
Canadian models are equipped with this warning light:
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.

Anti-lock Brake System ABS
If the warning light comes on, there is a malfunction of the ABS system (the standard braking system pwill however
function). The vehicle should be driven to a Volvo retailer for inspection. See page 17
for additional information.

Many fuels contain benzene as a solvent. Unburned benzene has been strongly linked to certain forms of cancer. If you
live in an area where you must fill your own gas tank, take precautions. These may include:
standing upwind away from the filler nozzle while refueling
refueling only at gas stations with vapor recovery systems that fully seal the mouth of the filler neck during refueling
wear neoprene gloves while handling a fuel filler nozzle.
Use of Additives
With the exception of gas line antifreeze during winter months, do not add solvents, thickeners, or other store -bought
additives to your car's fuel, cooling, or lubricating systems. Overuse may damage your engine, and some of these
additives contain organically volatile chemicals. Do not needlessly expose yourself to these chemicals.
pg. 72 Refueling
Refueling
The fuel tank is designed to hold approximately 21.1 US gal. (80 liters) with sufficient volume left over to
accommodate possible expansion of the fuel in hot weather. Be aware that the "usable" tank capacity will be somewhat
less than the specified maximum. When the fuel level is low, such factors as ambient temperature, the fuel's "Reid
vapor pressure" characteristics, and terrain can affect the fuel pumps' ability to supply the engine with an adequate
supply of fuel. Therefore, it is advisable to refuel as soon as possible when the needle nears the red zone, or when the
fuel warning light comes on.
Fuel filler door
Press the button on the light switch panel (see illustration on page 32
) when the car is at a standstill to unlock the fuel
filler door. Please note that the fuel filler door will remain unlocked until the car begins to move forward. An audible
click ill be heard when the fuel filler door relocks.
If you intend to leave your car while it is being refueled, this feature enables you to lock the doors/trunk while leaving
the fuel filler door unlocked.
You can also keep the car locked if you remain inside it during refueling. The central locking button does not lock the
fuel filler door. Be sure the fuel filler door is not obstructed and is completely closed after refueling.
Open the fuel filler cap slowly during hot weather conditions.
NOTE: During a transitional period, a small number of service stations may still have fuel nozzles that are not
compatible with the fuel filler neck on cars equipped with the evaporative control system. Please refer to page 117
for
additional information.
WARNING!
Never carry a cell phone that is switched on while refueling your vehicle. If the phone rings, this may cause a spark
that could ignite gasoline fumes, resulting in fire and injury.

CAUTION:
Do not refuel with the engine running *. Turn the ignition off or to position I. If the ignition is on, an incorrect
reading could occur in the fuel gauge.
After refueling, close the fuel filler cap by turning it clockwise until it clicks into place *.
Allow for fuel expansion by not overfilling the tank. Overfilling could also cause damage to the emission control
systems.
Avoid spilling gasoline during refueling. In addition to causing damage to the environment, gasolines containing
alcohol can cause damage to painted surfaces, which may not be covered under the New Vehicle Limited Warranty.
Do not use gasolines containing methanol (methyl alcohol, wood alcohol). This practice can result in vehicle
performance deterioration and can damage critical parts in the fuel system. Such damage may not be covered under the
New Vehicle Limited Warranty.
* If the fuel filler cap is not closed tightly or if the engine is running when the car is refueled, the Check Engine
Light (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.
pg. 73 Starting the engine
Starting the engine
1. Fasten the seat belt.
WARNING!
Before starting, check that the seat, steering wheel and mirrors are adjusted properly. Make sure the brake pedal can
be depressed completely. Adjust the seat if necessary. See page 52
.
2. Apply the parking brake, if not already set. The gear selector is locked in the (P)ark position (SHIFTLOCK).
3. Without touching the accelerator pedal, turn the ignition key* to the starting position. Allow the starter to operate
for up to 5 seconds (turbo: 10 seconds). Release the key as soon as the engine starts. If the engine fails to start, repeat
this step.
NOTE: On certain models, when the car is started, idle speed may be noticeably higher than normal for a short period,
depending on the temperature of the engine.
This has been done to help bring components in the emission control system to their normal operating temperature as
quickly as possible, which enables them to function normally.
For cold starts at altitudes above 6000 ft (1800 meters), depress the accelerator pedal halfway and turn the key to the
starting position. Release the pedal slowly when the engine starts.
4. To release the gear selector from the (P)ark position, the engine must be running (or the ignition key must be in
position II) and the brake pedal must be depressed. While keeping firm pressure on the brake pedal, release the parking
brake.
5. Select the desired gear. The gear engages after a very slight delay which is especially noticeable when selecting R.
NOTE:
Your car is equipped with a KEYLOCK system. When the engine is switched off, the gear selector must be in the
( P )ark position before the key can be removed from the ignition switch.

"kickdown" to help improve fuel economy.
Cooling system
The risk for engine overheating is greatest, especially in hot weather, when:
Towing a trailer up steep inclines for prolonged periods at wide open throttle and low engine rpm.
Stopping the engine suddenly after high speed driving (so-called "after-boiling" can occur).
To avoid overheating, the following rules should be followed:
Do not drive for prolonged periods at engine speeds above 4500 rpm if you are towing a trailer in hilly terrain.
Reduce speed when towing a trailer up long, steep inclines. The risk of overheating can be reduced by switching off
the air conditioning system for a short time.
Do not let the engine idle unnecessarily for prolonged periods.
Do not mount auxiliary lamps in front of the grill.
When the risk of overheating is imminent, or in the event of overheating (the temperature gauge goes repeatedly into,
or stays continually in, the red section), the following precautions should be taken:
Switch off the air conditioning system.
Pull off the road, away from traffic, stop the car and put the gear selector into Park. Do not stop the engine!
Switch the heater to full (maximum) position. Increase the engine speed to approx. 2000 rpm (twice idling speed)
until the temperature begins to drop.
If the warning light in the center of the instrument panel is red, and the message "Coolant level lo stop engine" is
displayed, switch off the engine as soon as possible.
WARNING!
Do not remove coolant expansion tank cap. The coolant will be extremely hot.
If necessary, see page 118
for information on checking and topping-up the coolant level.

the vehicle and others sharing the roadway. Avoiding distractions is part of that responsibility.
The following should be checked regularly: *
1 Washer fluid reservoir should be filled with water and solvent (wintertime: windshield washer anti-freeze). See
page 120.
2 Power steering - When cold, the level must not be above the COLD mark and when hot it must not be above the
HOT mark. Top up if the level drops to the ADD mark with ATF fluid. See page 124.
3 Coolant level should be between the expansion tank marks. Mixture: 50% anti-freeze and 50% water. See page 118.
4 Engine oil level should be between the dipstick marks. The distance between the marks represents approx.
1.6 US qts (1.5 liters). See page 123.
5 Brake fluid - check, without removing the cap, that the level is above the MIN mark. Use brake fluid DOT 4+. See
page 124.
* Engine oil should be checked each time the car is refuelled.
