engine overheat VOLVO XC90 2003 Owners Manual

2003 VOLVO XC90
- For cold starts at altitudes above 6000 ft (1800 meters), depress th\
e accelerator pedal halfway and turn
the key to the starting position. Release the pedal slowly when the engi\
ne 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.
5. Select the desired gear. The gear engages after a very slight delay w\
hich is especially noticeable when
selecting R.
NOTE: Your vehicle is equipped with a Keylock system. When the engine is switc\
hed 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 t\
emperature.
Do not race a cold engine immediately after starting. Oil flow may not r\
each some lubrication points fast
enough to prevent engine damage.
* If two of the keys to your vehicle are close together, e.g., on the sa\
me key ring, when you try to start
the vehicle, this could cause interference in the immobilizer system and\
result in the vehicle not starting.
If this should occur, remove one of the keys from the key ring before tr\
ying to start the vehicle again. CAUTION
Automatic transmission
The engine should be idling when you move the gear selector. Never accel\
erate until after you feel
the transmission engage! Accelerating immediately after selecting a gear\
will cause harsh engagement
and premature transmission wear.
Selecting P or N when idling at a standstill for prolonged periods of time will help pre\
vent
overheating of the automatic transmission fluid.
WARNING!
Always place the gear selector in Park and apply the parking brake befor\
e leaving the vehicle. Never
leave the vehicle unattended with the engine running.
Always open garage doors fully before starting the engine inside a garag\
e to ensure adequate
ventilation. The exhaust gases contain carbon monoxide, which is invisib\
le and odorless but very
poisonous.

pg. 103 Starting and driving
Towing a trailer
Volvo recommends the use of Volvo trailer hitches that are specially des\
igned for the vehicle.
l Maximum trailer weights recommended by Volvo are:
All models - trailers without brakes: 1,650 lbs (750 kg)
Models with all wheel drive - trailers with brakes: 4,960 lbs (2250 kg)\

Models with front wheel drive - trailers with brakes: 3,970 lbs (1800 k\
g)
Observe the legal requirements of the state/province in which the vehicl\
es are registered.
l All Volvo models are equipped with energy-absorbing shock-mounted bumper\
s. Trailer hitch
installation should not interfere with the proper operation of this bump\
er system.
Trailer towing does not normally present any particular problems, but ta\
ke into consideration:
l Increase tire pressure to recommended full. See section "Wheels and tire\
s."
l When your vehicle is new, avoid towing heavy trailers during the first 6\
20 miles (1,000 km).
l Recommended hitch tongue load is: Trailer weights below 2,650 lbs (1,200 kg) - 110 lbs (50 kg)
Trailer weights above 2,650 lbs (1,200 kg) - 198 lbs (90 kg)
l Maximum speed when towing a trailer: 50 mph (80 km/h).
l Engine and transmission are subject to increased loads. Therefore, engin\
e coolant temperature should
be closely watched when driving in hot climates or hilly terrain. Use a \
lower gear and turn off the air
conditioner if the temperature gauge needle enters the red range.
l If the automatic transmission begins to overheat, a message will be disp\
layed in the text window.
l Avoid overload and other abusive operation.
l Hauling a trailer affects handling, durability, and economy.
l It is necessary to balance trailer brakes with the towing vehicle brakes\
to provide a safe stop (check
and observe state/local regulations).
l Do not connect the trailer's brake system directly to the vehicle's brak\
e system.
l More frequent vehicle maintenance is required.
l Remove the ball and drawbar assembly when the hitch is not being used.
l Volvo recommends the use of synthetic engine oil when towing a trailer o\
ver long distances or in
mountainous areas.

Three-way catalytic converter cautions
l Keep your engine properly tuned. Certain engine malfunctions, particular\
ly involving the electrical,
fuel or distributor ignition systems, may cause unusually high three-way\
catalytic converter
temperatures. Do not continue to operate your vehicle if you detect engi\
ne misfire, noticeable loss of
power or other unusual operating conditions, such as engine overheating \
or backfiring. A properly tuned
engine will help avoid malfunctions that could damage the three-way cata\
lytic converter.
l Do not park your vehicle over combustible materials, such as grass or le\
aves, which can come into
contact with the hot exhaust system and cause such materials to ignite u\
nder certain wind and weather
conditions.
l Excessive starter cranking (in excess of one minute), or an intermitte\
ntly firing or flooded engine can
cause three-way catalytic converter or exhaust system overheating.
l Remember that tampering or unauthorized modifications to the engine, the\
Electronic Control
Module, or the vehicle may be illegal and can cause three-way catalytic \
converter or exhaust system
overheating. This includes:
- Altering fuel injection setting or components.
- Altering emission system components or location or removing components\
.
- Repeated use of leaded fuel.
NOTE: Unleaded fuel is required for vehicles with three-way catalytic converte\
rs.
