The gauge indicates the temperature of the engine cooling system. If the\
temperature is abnormally high and the
needle enters the red zone, a message is shown in the display. Bear in m\
ind that auxiliary lamps in front of the air
intake reduce the cooling capacity at high outside temperatures and high\
engine loads.

WARNING
Driving with the trunk open: Driving with the trunk open could lead to poisonous exhaust gases
entering the passenger compartment. If the trunk must be kept open for a\
ny reason, proceed as follows:
l Close the windows
l Set the ventilation system control to air flow to floor, windshield and \
side windows and the blower
control to its highest setting.
Weight distribution affects handling
At the specified curb weight your vehicle has a tendency to understeer, \
which means that the steering
wheel has to be turned more than might seem appropriate for the curvatur\
e of a bend. This ensures good
stability and reduces the risk of rear wheel skid. Remember that these p\
roperties can alter with the vehicle
load. The heavier the load in the cargo area, the less the tendency to u\
ndersteer.
Handling, roadholding
Vehicle load, tire design and inflation pressure all affect vehicle hand\
ling. Therefore,
123 06 Starting and driving
General information
check that the tires are inflated to the recommended pressure according \
to the vehicle load. See the "Tire
pressure" section. Loads should be distributed so that capacity weight o\
r maximum permissible axle loads
are not exceeded.
Driving through water
The vehicle can be driven through water up to a depth of approximately 9\
in. (25 cm), at a maximum
speed of 6 mph (10 km/h).
l Take particular care when driving through flowing water.
l Clean the electrical connections for trailer wiring after driving in mud\
or water
l When driving through water, maintain low speed and do not stop in the wa\
ter.
WARNING
After driving through water, press lightly on the brake pedal to ensure \
that the brakes are functioning
normally. Water or mud can make the brake linings slippery, resulting in\
delayed braking effect.

CAUTION
l Engine damage will occur if water is drawn into the air cleaner.
l If the vehicle is driven through water deeper than 9 in (25 cm), water\
may enter the differential and
the transmission. This reduces the oil's lubricating capacity and may sh\
orten the service life of these
components.
l Do not allow the vehicle to stand in water up to the door sills longer t\
han absolutely necessary. This
could result in electrical malfunctions.
l If the engine has been stopped while the car is in water, do not attempt\
to restart the engine. Have the
car towed out of the water.
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 types of an\
tifreeze 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 vehicle durin\
g cold weather.
l Try to keep the fuel tank well filled - this prevents the formation of c\
ondensation 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 (t\
hinner oil) improves cold-weather
starting as well as decreasing fuel consumption while the engine is warm\
ing up. For winter use, 5W-30
oil, particularly the synthetic type
1, is recommended. Be sure to use good quality oil but do not use cold-
weather oil for hard driving or in warm weather. See
page 239 for more information.
l The load placed on the battery is greater during the winter since the wi\
ndshield wipers, lighting, etc. are
used more often. Moreover, the capacity of the battery decreases as the \
temperature drops. In very cold
weather, a poorly charged battery can freeze and be damaged. It is there\
fore advisable to check the state
of
1Synthetic oil is not used when the oil is changed at the normal maintena\
nce intervals except at owner request and
at additional charge. Please consult your Volvo retailer.
124 06 Starting and driving
General information
charge more frequently and spray an antirust oil on the battery posts.
l Volvo recommends the use of snow tires on all four wheels for winter dri\
ving - see the chapter "Wheels
and tires."

tire inflation pressure placard is also located on the driver's side Bpi\
llar (the structural member at the side
of the vehicle, at the rear of the driver's door opening). This placard\
indicates the designation of the
factory-mounted tires on your vehicle, as well as load limits and inflat\
ion pressure.
NOTE
The placards shown indicate inflation pressure for the tires installed o\
n the car at the factory
only.
l Use a tire gauge to check the tire inflation pressure, including the spa\
re, at least once a month and
before long trips. You are strongly urged to buy a reliable tire pressur\
e gauge, as automatic service station
gauges may be inaccurate.
l Use the recommended cold inflation pressure for optimum tire performance\
and wear.
l Under-inflation or over-inflation may cause uneven treadwear patterns.
WARNING
l Under-inflation is the most common cause of tire failure and may result \
in severe tire cracking, tread
separation, or "blowout," with unexpected loss of vehicle control and in\
creased risk of injury.
l Under-inflated tires reduce the load carrying capacity of your vehicle. \
When weather temperature changes occur, tire inflation pressures also ch\
ange. A 10- degree temperature
drop causes a corresponding drop of 1 psi (7 kPa) in inflation pressur\
e. Check your tire pressures
frequently and adjust them to the proper pressure, which can be found on\
the vehicle's tire information
placard or certification label.

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 inflati\
on pressure is affected by the number
of occupants in the car, the amount of cargo, and the speed at which the\
vehicle will be driven for a
prolonged period.
This information can be found on the tire inflation placard(s) located\
on the driver's side B-pillar or on the
inside of the fuel filler door on Canadian models, and in the tire infla\
tion 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
Vehicle loading
Properly loading your vehicle will provide maximum return of vehicle des\
ign performance.
Before loading your vehicle, familiarize yourself with the following ter\
ms for determining your vehicle's
weight ratings, with or without a trailer, from the vehicle's Federal/Ca\
nadian Motor Vehicle Safety
Standards (FMVSS/ CMVSS) label, and the vehicle's tire information pla\
card:
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 "Towing a tr\
ailer" on
page
146.

Permissible axle weight
The maximum allowable weight that can be carried by a single axle (fron\
t or rear). These numbers are
shown on the Federal/Canadian Motor Vehicle Safety Standards (FMVSS/CMV\
SS) label. The total load
on each axle must never exceed its maximum permissible weight.
Gross vehicle weight (GVW)
The vehicle's curb weight + cargo + passengers.
NOTE
l The location of the various labels in your vehicle can be found on page 235.
l A table listing important weight limits for your vehicle can be found on\
page
237.
Steps for Determining Correct Load Limit
1. Locate the statement ''the combined weight of occupants and cargo sho\
uld never exceed XXX pounds''
on your vehicle's placard.
2. Determine the combined weight of the driver and passengers that will \
be riding in your vehicle.
3. Subtract the combined weight of the driver and passengers from XXX ki\
lograms or XXX pounds.
4. The resulting figure equals the available amount of cargo and luggage\
load capacity. For example, if
the ''XXX'' amount equals 1400 lbs. and there will be five 150 lb. passe\
ngers in your vehicle, the amount
of available cargo and luggage load capacity is 650 lbs. (1400-750 (5 \
x 150) = 650 lbs.)
5. Determine the combined weight of luggage and cargo being loaded on th\
e vehicle. That weight may not
safely exceed the available cargo and luggage load capacity calculated i\
n Step 4.
6. If your vehicle will be towing a trailer, load from your trailer will\
be transferred to your vehicle.

cargo and luggage load capacity of your vehicle.
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 gradings
Uniform tire quality gradings
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) tim\
es as well on the government
course as a tire graded 100.
The relative performance of tires depends upon the actual conditions of \
their use, however, and many
depart significantly from the norm due to variation in driving habits, m\
aintenance 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 ma\
rked C may have poor traction
performance.
