2003 VOLVO S80 towing

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:
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 121
. 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.
pg. 27 Indicator and warning lights
Rear fog light
This light indicates that the rear fog light is on.
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 will still
however function). The vehicle should be driven to a Volvo retailer for inspection. See page 17
for additional
information.

Stability Traction Control (STC) system (option), or Dynamic Stability and Traction Control (DSTC) system
(option)
This indicator light will flash with STC or DSTC is actively working to stabilize the car. See pages 18-19
for more
detailed information.
Turn signal indicator - trailer (certain models)
If you are towing a trailer, this light will flash simultaneously with the turn signals on the trailer. If the light does not
flash when signaling, neither the trailer's turn signals nor the car's turn signals are functioning.
Seat belt reminder This symbol lights up to indicate that the driver has not fastened his/her seat belt.

Octane rating
Volvo engines are designed for optimum performance on unleaded premium gasoline with an octane rating AKI of 91,
or above. AKI (ANTI KNOCK INDEX) is an average of the Research Octane Number, RON, and the Motor Octane
Number, MON. (RON + MON/2).
The minimum octane requirement is AKI 87 (RON 91).

Neutral - no gear engaged. Use the parking brake.
D (Drive)
D is the normal driving position and should be used as often as possible to help improve fuel economy. The car should
not be moving when shifting from R to the D position.
3 (Intermediate gear)
The transmission will shift automatically between gears 3, 2 or 1 from this position. The transmission cannot shift up
to (D)rive (D) from third gear.
2 (Intermediate gear)
The transmission will shift automatically between gears 2 and 1 from this position. The transmission cannot shift up
to third gear from second gear.
1 (Low gear)
If you select this gear at speeds above 30 mph (50 km/h), the transmission will first shift to second gear and then to
first gear at lower speeds.
NOTE: The intermediate and low gears can be used for:
Driving in a mountainous area
Towing a trailer
Increasing the braking effect of the engine.
The transmission has a built-in limiter designed to help prevent excessive engine speeds (high rpm) when gears 3, 2
or 1 are selected.
Kickdown
Automatic shift to a lower gear (kickdown) is achieved by depressing the accelerator pedal fully and briskly. An
upshift will occur when approaching the top speed for a particular gear or by releasing the accelerator pedal slightly.
Kickdown can be used for maximum acceleration or when passing at highway speeds.
Automatic transmission - adaptive system
The automatic transmission is controlled by an adaptive control system that constantly monitors the way in which the
transmission functions. It senses and adapts each gear shift for optimal performance. The system also monitors your
particular driving style and adapts gear shifting accordingly.
pg. 75 Automatic transmission
Automatic transmission - shift gate positions
The gear selector can be moved freely between N and D.
Depressing the selector knob enables you to move the gear selector to positions P, R, N, D, 3, 2 and 1.

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 Service intervals.
NOTE : Vehicles equipped with automatic transmissions should use (D)rive as often as possible and avoid using
"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 116
for information on checking and topping-up the coolant level.

To remove a defective bulb:
Switch off the ignition.
Open the hood.
Remove the plastic cover over the bulb (1) by turning it counterclockwise.
Remove the connector (2).
Loosen the retaining spring (3) by first moving it to the right and then moving it down, out of the way.
Pull out the defective bulb. Note the position of the guide lug on the base of the bulb (4).
Installing a new bulb
To install a new bulb:
Insert the new bulb, without touching the glass, with the guide lug upward (1). The bulb will only seat properly in
this position.
Move the retaining spring up and push it slightly to the left until it seats properly (2).
Press the connector into place on the bulb (3).
Reinstall the plastic cover and turn it clockwise until it is correctly in place (4). "TOP" must be upward.
NOTE: If the vertical aim of your headlights needs to be adjusted for any reason (e.g., towing a trailer for extended
periods), this should be done by an authorized Volvo retailer.

Engine specifications Designation: Volvo B 6294 T
Output 268 hp at 5200 rpm (200 KW/87 rps)
Max torque 280 ft. lbs. at 1800-5000 rpm (380 Nm at 30-83 rps)
Number of cylinders 6
Bore 3.27" (83 mm)
Stroke 3.54" (90 mm)
Displacement 2.92 liters (115 cu. in.)
Compression ratio 8.5:1
Number of valves 24
Charge air cooler (Intercooler)
Turbocharged engines employ a turbo-compressor to force air into the engine inlet manifold and a charge air cooler to
cool the compressed inlet air. The resulting increase in air flow raises pressure in the intake manifold and increases
engine power over that developed by the normally-aspirated engine. The charge air cooler (which resembles a radiator)
is located between the turbo-compressor and inlet manifold. Designation: Volvo B 6294 S
