2006 VOLVO XC90
WARNING!
Loads carried on the vehicle's roof should not exceed 220 lbs (100 kg)\
, including the weight of the
load carriers and any other load carrying equipment (ski boxes, bicycle\
racks, etc.). Excessive loads
on the roof can adversely affect the handling and roadholding characteri\
stics of the vehicle.
Load carrier cover
The vehicle's ignition key or the stud on the edge of the supplied torqu\
e wrench can be used to undo or
tighten the cover. Turn a quarter turn (90 degrees). See illustration.\

Cold weather precautions
If you wish to check your vehicle before the approach of cold weather, t\
he following advice is worth
noting:
l Make sure that the engine coolant contains 50 percent antifreeze. Any ot\
her mixture will reduce
freeze protection. This gives protection against freezing down to -31°\
F (-35°C). See section "Coolant".
The use of "recycled" antifreeze is not approved by Volvo. Different typ\
es of antifreeze must not
be mixed.
l Volvo recommends using only genuine Volvo antifreeze in your vehicle's r\
adiator. Your Volvo
retailer stocks plenty of Volvo engine coolant to help protect your vehi\
cle during cold weather.
l Try to keep the fuel tank well filled - this prevents the formation of condensation in the tank. \
In
addition, in extremely cold weather conditions it is worthwhile to add f\
uel line de-icer before refueling.
l The viscosity of the engine oil is important. Oil with low viscosity (thinner oil) improves cold-
weather starting as well as decreasing fuel consumption while the engine\
is warming up. For winter use,
5W-30 oil, particularly the synthetic type*, is recommended. Be sure to \
use good quality oil but do not
use cold-weather oil for hard driving or in warm weather. See section "E\
ngine oil" for more information.
l The load placed on the battery is greater during the winter since the windshield wipers, lighting, etc\
.

l PSI: Pounds per square inch, a standard unit of air pressure.
l B-pillar: The structural member at the side of the vehicle behind the front door\
.
l Bead area of the tire: Area of the tire next to the rim.
l Sidewall of the tire: Area between the bead area and the tread.
l Tread area of the tire: Area of the perimeter of the tire that contacts the road when mounted \
on the
vehicle.
l Rim: The metal support (wheel) for a tire or a tire and tube assembly upo\
n which the tire beads are
seated.
l Maximum load rating: a figure indicating the maximum load in pounds and kilograms that can \
be
carried by the tire. This rating is established by the tire manufacturer\
.
l Maximum permissible inflation pressure: the greatest amount of air pressure that should ever be
put in the tire. This limit is set by the tire manufacturer.
l Recommended tire inflation pressure: inflation pressure, established by Volvo, which is based on
the type of tires that are mounted on a vehicle at the factory. This inf\
lation pressure is affected by the
number of occupants in the car, the amount of cargo, and the speed at wh\
ich the vehicle will be driven
for a prolonged period. This information can be found on the tire inflat\
ion placard(s) located on the
driver's side B-pillar or on the inside of the fuel filler door on Canad\
ian models, and in the tire inflation
table in this chapter.
l Cold tires: The tires are considered to be cold when they have the same temperatur\
e as the
surrounding (ambient) air. This temperature is normally reached after \
the car has been parked for at least
3 hours.

Vehicle loading
Properly loading your vehicle will provide maximum return of vehicle des\
ign performance. Before
loading your vehicle, familiarize yourself with the following terms for \
determining your vehicle's weight
ratings, with or without a trailer, from the vehicle's Federal/Canadian \
Motor Vehicle Safety Standards
(FMVSS/CMVSS) label, and the vehicle's tire information placard:
Curb weight
The weight of the vehicle including a full tank of fuel and all standard\
equipment. It does not include
passengers, cargo, or optional equipment.
Capacity weight
All weight added to the curb weight, including cargo and optional equipm\
ent. When towing, trailer hitch
tongue load is also part of cargo weight.
NOTE: For trailer towing information, please refer to the section "Towin\
g a trailer" on
page 104.
Permissible axle weight

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.
