engine overheat VOLVO XC90 2007 Owners Manual

2007 Volvo XC90
- Select the desired gear. The gear engages after a very slight delay wh\
ich is especially noticeable when selecting R.
NOTE: Your vehicle 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. W\
hen starting in cold weather, the
transmission may shift up at slightly higher engine speeds than normal u\
ntil the automatic transmission fluid reaches
normal operating temperature.
NOTE: Do not race a cold engine immediately after starting. Oil flow may not \
reach some lubrication points fast enough
to prevent engine damage.
WARNING!
An extra mat on the driver's floor can cause the accelerator pedal to ca\
tch. Check that the movement of the accelerator
pedal is not impeded. No more than one protective floor covering may be \
used at one time.
1. 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 sta\
rting. If this should occur, remove one of the keys from the key
ring before trying to start the vehicle again.
2. On vehicles equipped with the autostart feature, release the key imme\
diately. See also
page 121.

Starting the vehicle
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 befor\
e starting the engine inside a garage to ensure
adequate ventilation. The exhaust gases contain carbon monoxide, which i\
s invisible and odorless but very poisonous.
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 ti\
me will help prevent overheating of the automatic
transmission fluid.

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 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 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.
NOTE:
l When parking the vehicle with a trailer on a hill, apply the parking bra\
ke before putting the gear selector in (P)ark.
When starting on a hill, put the gear selector in (D)rive before relea\
sing the parking brake. Always follow the trailer
manufacturer's recommendations for wheel chocking.
l If you use the manual (Geartronic) shift positions while towing a trai\
ler, make sure the gear you select does not put too
much strain on the engine (using too high a gear).
WARNING!
l Bumper-attached trailer hitches must not be used on Volvos, nor should s\
afety chains be attached to the bumper.
l Trailer hitches attaching to the vehicle rear axle must not be used.
l Never connect a trailer's hydraulic brake system directly to the vehicle\
brake system, nor a trailer's lighting system
directly to the vehicle lighting system. Consult your nearest authorized\
Volvo retailer for correct installation.
l When towing a trailer, the trailer's safety wire must be correctly faste\
ned to the hole or hook provided in the trailer
hitch on the vehicle. The safety wire should never be fastened to or wou\
nd around the drawbar ball.

Towing a trailer
Smoother starts with a trailer
Models equipped with the V8-engine and the 6-speed automatic transmissio\
n have a built-in function that reduces
acceleration slightly in first gear when the vehicle is towing a trailer\
. This is done to help avoid wheel spin and to make
starting off smoother.
l This function is activated when the trailer's electrical connector is pl\
ugged into the electrical socket mounted near the
trailer hitch.
l The function is automatically deactivated when the trailer's wiring is d\
isconnected from the socket. The vehicle will
then accelerate normally.
NOTE: Since this function is activated when a connector is plugged into the e\
lectrical socket near the trailer hitch, it will
be activated by any electrical equipment (e.g. bicycle racks with light\
ing, etc) that is plugged in, and will remain active
until the equipment is unplugged from the socket.
Leveling
If your vehicle is equipped with automatic leveling, the rear suspension\
always retains the correct ride height regardless of
the load.
l The system adjusts the rear suspension to the correct level after the ve\
hicle has been driven a short distance.

Three-way catalytic converter
Points to keep in mind
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 convert\
ers.
