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.

Stability Traction Control (STC) system (option), or Dynamic Stability and Traction Control (DSTC) system

long objects.
To fold down the backrest(s):
Pull the release control handle(s) in the trunk to release the backrest(s) (see illustration above). If the outboard rear
head restraints are folded down, they should be returned to the upright position before folding the backrest down. It
may be necessary to manually adjust the center head restraint.
Fold the backrest down.
WARNING!
All S80 cars feature 60/40 split fold-down rear seats. This function is performed by handles inside the trunk, and
also provides a means for children and adults to enter the passenger compartment in the event they become locked
inside the trunk.
Adults are advised to familiarize themselves with the operation and location of the release handles.
To fold down the rear seats from inside the trunk, pull the release control handles located on either side of the trunk.
WARNING!
Keep vehicle doors and the luggage compartment locked and keep keys out of a child's reach. Unsupervised
children could lock themselves in an open trunk and risk injury. Children should be taught not to play in vehicles.
On hot days, the temperature in the trunk or vehicle interior can rise very quickly. Exposure of people to these
high temperatures for even a short period of time can cause heat-related injury or death. Small children are
particularly at risk.
WARNING!
When the backrest is returned to the upright position, check that it is properly locked in place. Return the head
restraints to the upright position.
Long loads should always be securely anchored to help avoid injury in the event of a sudden stop.
Always turn the engine off and apply the parking brake when loading/unloading the vehicle.
Place the transmission in the P (PARK) position to help prevent inadvertent movement of the gear selector.

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.

When starting in cold weather, the transmission may shift up at slightly higher engine speeds than normal until the
automatic transmission fluid reaches normal operating temperature.
CAUTION:
The engine should be idling when you move the gear selector. Never accelerate until after you feel the transmission
engage! Accelerating immediately after selecting a gear will cause harsh gear engagement and premature transmission
wear.
Selecting P or N when idling at a standstill for prolonged periods of time will help prevent overheating of the
automatic transmission fluid.
Do not race a cold engine immediately after starting. Oil flow may not reach some lubrication points fast enough to
prevent engine damage.
WARNING!
Always place the gear selector in Park and apply the parking brake before leaving the vehicle. Never leave the car
unattended with the engine running.
Always open the garage doors fully before starting the engine inside a garage to ensure adequate ventilation. The
exhaust gases contain carbon monoxide, which is invisible and odorless but very poisonous.
* Your car is equipped with an electronic start inhibitor (immobilizer). The keys you received with your car are
specially coded. The code in the key is transmitted to an antenna in the ignition switch where it is compared to the
code stored in the start inhibitor module. The car can only be started if a properly coded key is used.
If two of the keys to your car are close together, e.g., on the same key ring, when you try to start the car, this could
cause interference in the immobilizer system and result in the car not starting. If this should occur, remove one of the
keys from the key ring before trying to start the car again.
pg. 74 Automatic transmission
P (Park)
Use this position when starting the engine or parking the car.
Never use P while the car is in motion.
The parking brake should also be set whenever the car is parked.
The gear selector is mechanically locked in the P position (SHIFTLOCK). To release the gear selector from this
position, the engine must be running (or the ignition key must be in position II) and the brake pedal must be
depressed.
WARNING!
Never leave the car unattended when the engine is running. If, by mistake, the gear selector is moved from P, the car
may start moving.

R (Reverse)
Never engage R while the car is moving forward.
N (Neutral)
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 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.

replace the driver's attention and judgement.
pg. 80 Driving economy
Economical driving conserves natural resources
Better driving economy may be obtained by thinking ahead, avoiding rapid starts and stops and adjusting the speed of
your vehicle to immediate traffic conditions. Observe the following rules:
Bring the engine to normal operating temperature as soon as possible by driving with a light foot on the accelerator
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 car for driving short distances. This does not allow the engine to reach normal
operating temperature.
Drive carefully and avoid rapid acceleration and hard braking.
Do not exceed posted speed limits.
Avoid carrying unnecessary items (extra load) in the car.
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.
Avoid using automatic transmission kickdown feature unless necessary.
Avoid using the air conditioning when it is not required. When engaged, the A/C compressor places an additional
load on the engine. However, at higher 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 Service intervals.
NOTE : Vehicles equipped with automatic transmissions should use (D)rive as often as possible and avoid using
