engine overheat VOLVO S80 2003 Owners Manual

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)

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.
