overheating 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.

Vehicle loading
WARNING!
l Exceeding the permissible axle weight, gross vehicle weight, or any othe\
r weight rating limits can
cause tire overheating resulting in permanent deformation or catastrophi\
c failure.
l Do not use replacement tires with lower load carrying capacities than th\
e tires that were original
equipment on the vehicle because this will lower the vehicle's GVW ratin\
g. Replacement tires with a
higher limit than the originals do not increase the vehicle's GVW rating\
limitations.

Uniform Tire Quality Grading
ALL PASSENGER VEHICLE TIRES MUST CONFORM TO FEDERAL SAFETY
REQUIREMENTS IN ADDITION TO THESE GRADES
Quality grades can be found, where applicable, on the tire sidewall betw\
een the tread shoulder
and maximum section width. For example:
Treadwear 200 Traction AA Temperature A
TREADWEAR
The treadwear grade is a comparative rating based on the wear rate of th\
e tire when tested under
controlled conditions on a specified government test course. For example\
, a tire graded 150 would wear
one and one half (1 1/2) times as well on the government course as a t\
ire graded 100. The relative
performance of tires depends upon the actual conditions of their use, ho\
wever, and many depart
significantly from the norm due to variation in driving habits, maintena\
nce practices and differences in
road characteristics and climate.
TRACTION
The traction grades, from highest to lowest, are AA, A, B, and C, as mea\
sured under controlled
conditions on specified government test surfaces of asphalt and concrete\
. A tire marked C may have
poor traction performance.

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.
