General information
Economical driving conserves natural
resources
Better driving economy may be obtained by
thinking ahead, avoiding rapid starts and stops
and adjusting the speed of your vehicle to
immediate traffic conditions.
Observe the following rules:
•Bring the engine to normal operating tem-
perature as soon as possible by driving
with a light foot on the accelerator pedal for
the first few minutes of operation. A cold
engine uses more fuel and is subject to
increased wear.
•Whenever possible, avoid using the vehicle
for driving short distances. This does not
allow the engine to reach normal operating
temperature.
•Drive carefully and avoid rapid acceleration
and hard braking.
•Use the transmission's Drive (D) position
as often as possible and avoid using kick-
down.
•Using the transmission's Sport mode1 may
increase fuel consumption somewhat. Use
the transmission's Drive (D) position as
often as possible. See page 119 for addi-
tional information about Sport mode.
•Do not exceed posted speed limits.
•Avoid carrying unnecessary items (extra
load) in the vehicle.
•Maintain correct tire pressure. Check tire
pressure regularly (when tires are cold).
•Remove snow tires when threat of snow or
ice has ended.
•Note that roof racks, ski racks, etc,
increase air resistance and also fuel con-
sumption.
•At highway driving speeds, fuel consump-
tion will be lower with the air conditioning
on and the windows closed than with the
air conditioning off and the windows open.
•Using the onboard trip computer's fuel
consumption modes can help you learn
how to drive more economically.
Other factors that decrease gas mileage
are:
•Dirty air cleaner
•Dirty engine oil and clogged oil filter
•Dragging brakes
•Incorrect front end alignment
Some of the above mentioned items and others
are checked at the standard maintenance
intervals.
WARNING
Driving with the tailgate open: Driving with
the tailgate open could lead to poisonous
exhaust gases entering the passenger com-
partment. If the tailgate must be kept open
for any reason, proceed as follows:
•Close the windows
•Set the ventilation system control to air
flow to floor, windshield and side win-
dows and the blower control to its high-
est setting.
Weight distribution affects handlingAt 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 curvature of a
bend. This ensures good stability and reduces
the risk of rear wheel skid. Remember that
these properties can alter with the vehicle load.
The heavier the load in the cargo area, the less
the tendency to understeer.
Handling, roadholdingVehicle load, tire design and inflation pressure
all affect vehicle handling. Therefore, check
that the tires are inflated to the recommended
pressure according to the vehicle load. See the
"Tire pressure" section. Loads should be dis-

the ignition switched off, which drains the
battery.
Before a long distance tripIt is always worthwhile to have your vehicle
checked by a trained and qualified Volvo serv-
ice technician before driving long distances.
Your retailer will also be able to supply you with
bulbs, fuses, spark plugs and wiper blades for
your use in the event that problems occur.
As a minimum, the following items should be
checked before any long trip:
•Check that engine runs smoothly and that
fuel consumption is normal.
•Check for fuel, oil, and fluid leakage.
•Have the transmission oil level checked.
•Check condition of drive belts.
•Check state of the battery's charge.
•Examine tires carefully (the spare tire as
well), and replace those that are worn.
Check tire pressures.
•The brakes, front wheel alignment, and
steering gear should be checked by a
trained and qualified Volvo service techni-
cian only.
•Check all lights, including high beams.
•Reflective warning triangles are legally
required in some states/provinces.
•Have a word with a trained and qualified
Volvo service technician if you intend to
drive in countries where it may be difficult
to obtain the correct fuel.
•Consider your destination. If you will be
driving through an area where snow or ice
are likely to occur, consider snow tires.
Cold weather precautionsIf you wish to check your vehicle before the
approach of cold weather, the following advice
is worth noting:
•Make sure that the engine coolant contains
50 percent antifreeze. Any other mixture
will reduce freeze protection. This gives
protection against freezing down to
–31 °F (–35 °C). The use of "recycled" anti-
freeze is not approved by Volvo. Different
types of antifreeze must not be mixed.
•Volvo recommends using only genuine
Volvo antifreeze in your vehicle's radiator.
•Try to keep the fuel tank well filled – this
helps prevent the formation of condensa-
tion in the tank. In addition, in extremely
cold weather conditions it is worthwhile to
add fuel line de-icer before refueling.
•The viscosity of the engine oil is important.
Oil with low viscosity (thinner oil) improves
cold-weather starting as well as decreas-
ing fuel consumption while the engine is
warming up. 0W-30 oil is recommended fordriving in areas with sustained low temper-
atures.
•The load placed on the battery is greater
during the winter since the windshield wip-
ers, lighting, etc., are used more often.
Moreover, the capacity of the battery
decreases as the temperature drops. In
very cold weather, a poorly charged bat-
tery can freeze and be damaged. It is there-
fore advisable to check the state of charge
more frequently and spray an anti-rust oil
on the battery posts.
•Volvo recommends the use of snow tires
on all four wheels for winter driving, see
page 306.
•To prevent the washer fluid reservoir from
freezing, add washer solvents containing
antifreeze. This is important since dirt is
often splashed on the windshield during
winter driving, requiring the frequent use of
the washers and wipers. Volvo Washer
Solvent should be diluted as follows: Down
to 14 °F (–10 °C): 1 part washer solvent and
4 parts water Down to 5 °F (–15 °C): 1 part
washer solvent and 3 parts water Down to
0 °F (–18 °C): 1 part washer solvent and
2 parts water Down to –18 °F (–28 °C):
1 part washer solvent and 1 part water.
•Use Volvo Teflon Lock Spray in the locks.
•Avoid using de-icing sprays as they can
cause damage to the locks.

Towing a trailer
07
285 Introduction
Volvo recommends the use of Volvo trailer
hitches that are specially designed for the vehi-
cle.
NOTE
See page 361 for the maximum trailer and
tongue weights recommended by Volvo.
•Observe the legal requirements of the
state/province in which the vehicles are
•All Volvo models are equipped with
energy-absorbing shock-mounted bump-
ers. Trailer hitch installation should not
interfere with the proper operation of this
bumper system.
Trailer towing does not normally present any
particular problems, but take into considera-
tion:
•Increase tire pressure to recommended full
pressure. See the tire inflation table on
page 299.
•When your vehicle is new, avoid towing
heavy trailers during the first 620 miles
(1,000 km).
•Maximum speed when towing a trailer:
50 mph (80 km/h).
•Engine and transmission are subject to
increased loads. Therefore, engine coolant
temperature should be closely watchedwhen driving in hot climates or hilly terrain.
Use a lower gear and turn off the air con-
ditioner if the temperature gauge needle
enters the red range.
•If the automatic transmission begins to
overheat, a message will be displayed in
the text window.
•Avoid overload and other abusive opera-
tion.
•Hauling a trailer affects handling, durabil-
ity, and economy.
•It is necessary to balance trailer brakes
with the towing vehicle brakes to provide a
safe stop (check and observe state/local
regulations).
•Do not connect the trailer's brake system
directly to the vehicle's brake system.
•More frequent vehicle maintenance is
required.
•Remove the ball holder when the hitch is
not being used.
•Volvo recommends the use of synthetic
engine oil when towing a trailer over long
distances or in mountainous areas.
WARNING
•Bumper-attached trailer hitches must
not be used on Volvos, nor should
safety chains be attached to the
bumper.
•Trailer hitches attaching to the vehicle
rear axle must not be used.
•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 author-
ized Volvo retailer for correct installa-
tion.
•When towing a trailer, the trailer's safety
wire must be correctly fastened to the
hole or hook provided in the trailer hitch
on the vehicle. The safety wire should
never be fastened to or wound around
the drawbar ball.

289
WARNING
•When the vehicle is being towed, the
ignition should be in mode II (in mode I,
all of the vehicle's airbags are deacti-
vated). See page 83 for more informa-
tion about ignition modes.
•Never remove the remote key from the
ignition slot when the vehicle is being
towed. For vehicles with keyless drive,
the remote key must remain inside the
vehicle.
•The power brakes and power steering
will not function when the engine is not
running. Approximately 5 times more
pressure will be required on the brake
pedal and the steering wheel will be
considerably harder to turn.
•The towing eyelets must not be used for
pulling the vehicle out of a ditch or for
any similar purpose involving severe
strain. Do not use the towing eyelets to
pull the vehicle up onto a flat bed tow
truck.
Towing the vehicle
1. With the remote key fully pressed into the
ignition slot1, press START/STOP
ENGINE for approximately 2 seconds to
activate ignition mode II.
2. The remote key must remain in the ignition
slot
2 for the entire time that the vehicle is
being towed.
3. Keep the tow rope taut when the towing
vehicle slows down by applying light pres-
sure on the brake pedal. This will help pre-
vent jarring movements of the vehicle
being towed.
4. Be prepared to apply the brakes to stop the
vehicle being towed.
CAUTION
General towing precautions:
•Please check with state and local
authorities before attempting this type
of towing, as vehicles being towed are
subject to regulations regarding maxi-
mum towing speed, length and type of
towing device, lighting, etc.
•If the vehicle's battery is dead, attach
jumper cables (see page 116) to provide
current for releasing the electric parking
brake and to move the gear selector
from the P position to N. If this is not
possible, see page 120 for information
about manually overriding the shiftlock
system to move the gear selector from
P to N.
•Maximum speed: 50 mph (80 km/h). Do
not exceed the maximum allowable
towing speed.
•Maximum distance with front wheels on
ground: 50 miles (80 km).
•The vehicle should only be towed in the
forward direction.
1Not necessary in vehicles with the optional keyless drive.2For vehicles with the the optional keyless dirive, the remote key must be in the vehicle.

at 6-year intervals, even if it has never been
used.
A tire's age can be determined by the DOT
stamp on the sidewall (see the illustration).
A tire with e.g., visible cracks or discoloration
should be replaced immediately.
Tread wear indicator
G021829
The tires have wear indicator strips running
across or parallel to the tread. The letters TWI
are printed on the side of the tire. When
approximately 1/16" (1.6 mm) is left on the
tread, these strips become visible and indicate
that the tire should be replaced. Tires with less
than 1/16" (1.6 mm) tread offer very poor trac-
tion.
When replacing worn tires, it is recommended
that the tire be identical in type (radial) and sizeas the one being replaced. Using a tire of the
same make (manufacturer) will prevent altera-
tion of the driving characteristics of the vehicle.
Improving tire economy
•Maintain correct tire pressure. See the tire
inflation table on page 299.
•Drive smoothly: avoid fast starts, hard
braking and tire screeching.
•Tire wear increases with speed.
•Correct front wheel alignment is very
important.
•Unbalanced wheels impair tire economy
and driving comfort.
•Tires must maintain the same direction of
rotation throughout their lifetime.
•When replacing tires, the tires with the
most tread should be mounted on the rear
wheels to reduce the chance of oversteer
during hard braking.
•Hitting curbs or potholes can damage the
tires and/or wheels permanently.
Summer and winter tires
G021778
The arrows shows the direction of rotation of the
tire
•When switching between summer and
winter tires, mark the tires to indicate
where they were mounted on the car, e.g.,
LF = left front, RR = right rear
•Tires with tread designed to roll in only one
direction are marked with an arrow on the
sidewall.
•Incorrectly mounted tires impair the car's
braking properties and ability to force
aside rain, snow and slush.
•The tires with the most tread should always
be at the rear (to reduce the risk of skid-
ding).
•Contact a Volvo workshop if you are
unsure about the tread depth.

297 Inflation placard
G032521
Tire inflation placard
Tire inflationCheck tire inflation pressure regularly.
See the tire inflation table on page 299. A tire
inflation pressure placard is also located on the
driver's side B-pillar (the structural member at
the side of the vehicle, at the rear of the driver's
door opening). This placard indicates the des-
ignation of the factory-mounted tires on your
vehicle, as well as load limits and inflation pres-
sure.
NOTE
•The placards shown indicate inflation
pressure for the tires installed on the
vehicle at the factory only.
•A certain amount of air seepage from
the tires occurs naturally and tire pres-
sure fluctuates with seasonal changes
in temperature. Always check tire pres-
sure regularly.
•Use a tire gauge to check the tire inflation
pressure, including the spare, at least once
a month and before long trips. You are
strongly urged to buy a reliable tire pres-
sure gauge, as automatic service station
gauges may be inaccurate.
•Use the recommended cold inflation pres-
sure for optimum tire performance and
wear.
•Under-inflation or over-inflation may cause
uneven treadwear patterns.
WARNING
•Under-inflation is the most common
cause of tire failure and may result in
severe tire cracking, tread separation,
or "blow-out," with unexpected loss of
vehicle control and increased risk of
injury.
•Under-inflated tires reduce the load car-
rying capacity of your vehicle.
When weather temperature changes occur, tire
inflation pressures also change. A 10-degree
temperature drop causes a corresponding
drop of 1 psi (7 kPa) in inflation pressure. Check
your tire pressures frequently and adjust them
to the proper pressure, which can be found on
the vehicle's tire information placard or certifi-
cation label.
Checking tire pressure
Cold tires
Inflation pressure should be checked when the
tires are cold.
The tires are considered to be cold when
they have the same temperature as the sur-
rounding (ambient) air.
This temperature is normally reached after the
vehicle has been parked for at least 3 hours.

After driving a distance of approximately 1 mile
(1.6 km), the tires are considered to be hot. If
you have to drive farther than this distance to
pump your tire(s), check and record the tire
pressure first and add the appropriate air pres-
sure when you get to the pump.
If checking tire pressure when the tire is hot,
never "bleed" or reduce air pressure. The tires
are hot from driving and it is normal for pres-
sures to increase above recommended cold
pressures. A hot tire at or below recommended
cold inflation pressure could be significantly
under-inflated.
To check inflation pressure:1. Remove the cap from the valve on one tire,
then firmly press the tire gauge onto the
valve.
2. Add air to reach the recommended air
pressure.
3. Replace the valve cap.
4. Visually inspect the tires to make sure there
are no nails or other objects embedded
that could puncture the tire and cause an
air leak.
5. Check the sidewalls to make sure there are
no gouges, cuts, bulges or other irregular-
ities.6. Repeat this procedure for each tire, includ-
ing the spare.
NOTE
•If you overfill the tire, release air by
pushing on the metal stem in the center
of the valve. Then recheck the pressure
with your tire gauge.
•Some spare tires require higher inflation
pressure than the other tires. Consult
the tire inflation pressure table on page
299 or see the inflation pressure plac-
ard.
