support is activated. Brake support prepares
the brake system to react quickly, and the
brakes are applied slightly. This may be expe-
rienced as a light tug.
If the brakes are applied quickly, full braking
effect will be provided, even if pressure on the
brake pedal is light.
Auto-brakeIf a collision is imminent and the driver has not
applied the brakes, the auto-brake function is
activated without the driver pressing the brake
pedal. Limited brake force is applied to reduce
the vehicle’s speed when the collision occurs.
WARNING
The auto-brake function connot prevent a
collision but instead is intended to reduce
speed at the moment of impact. For full
braking effect, driver must apply the brakes.
NOTE
The auto-brake function is always on and
cannot be turned off.
Operation
Some settings are controlled from the center
console via a menu system. For information on
how the menu system is used, see page 122.
On and offTo switch Collision Warning on or off, go into
the menu Car settings Collision warning
settings and select On or Off. When the engine
is started, the setting that was selected when
it was switched off will be used.
Activating/deactivating warning signalsThe collision warning system’s audible and vis-
ual signals are activated automatically when
the engine is started if the collision warning
system is activated.
The audible warning signal can be activated/
deactivated by selecting the alternative On or
Off in Car settings Collision warning
settings Warning sound.
Setting a warning distanceThis setting determines the distance at which
the visual and audible warnings are triggered.
Select Long, Normal or Short under Car
settings Collision warning settings
Warning distance
The warning distance determines the level of
sensitivity used by the system. The warning
distance Long provides an earlier warning.
Begin by using Long and if the system gives
too many warnings, try changing to
Normal.
WARNING \b
The setting
Short should only be used
in situations where traffic is light and
moving at low speeds.
\b Collision Warning alerts the driver to the
risk of a collision but this function can-
not reduce the driver’s reaction time.
\b For Collision Warning to be as effective
as possible, it is recommended that Dis-
tance Alert be set to 4 or 5, see
page 179.
NOTE \b
When adaptive cruise control is used,
the warning light and signal will be used
by cruise control, even if they have been
deactivated by the driver.
\b In situations where traffic is moving at
considerably different speeds, or if the
vehicle ahead brakes suddenly, warn-
ings may be considered to be late, even
if the setting Long has been selected.
Checking settingsThe current Collision Warning settings can be
checked by going into the menu system at
Car
settings Collision warning settings. See
page 122 for more information on the menu
system.

202 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:
\b
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.
\b Whenever possible, avoid using the vehicle
for driving short distances. This does not
allow the engine to reach normal operating
temperature.
\b Drive carefully and avoid rapid acceleration
and hard braking.
\b Use the transmission\fs Drive (
D) position
as often as possible and avoid using kick-
down.
\b Do not exceed posted speed limits.
\b Avoid carrying unnecessary items (extra
load) in the vehicle.
\b Maintain correct tire pressure. Check tire
pressure regularly (when tires are cold). \b
Remove snow tires when threat of snow or
ice has ended.
\b Note that roof racks, ski racks, etc,
increase air resistance and also fuel con-
sumption.
\b 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.
\b Using the onboard trip computer\fs fuel
consumption modes can help you learn
how to drive more economically.
Other factors that decrease gas mileage
are:
\b Dirty air cleaner
\b Dirty engine oil and clogged oil filter
\b Dragging brakes
\b 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:
\b
Close the windows
\b 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-
tributed so that capacity weight or maximum
permissible axle loads are not exceeded.

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:
\b
Check that engine runs smoothly and that
fuel consumption is normal.
\b Check for fuel, oil, and fluid leakage
\b Have the transmission oil level checked.
\b Check condition of drive belts.
\b Check state of the battery\fs charge.
\b Examine tires carefully (the spare tire as
well), and replace those that are worn.
Check tire pressures.
\b The brakes, front wheel alignment, and
steering gear should be checked by a
trained and qualified Volvo service techni-
cian only.
\b Check all lights, including high beams.
\b Reflective warning triangles are legally
required in some states/provinces.
\b 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. \b
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:
\bMake 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.
\b Volvo recommends using only genuine
Volvo antifreeze in your vehicle\fs radiator.
\b 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.
\b 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. For winter use, 5W-30 oil, par-
ticularly the synthetic type, is recom-
mended. Be sure to use good quality oil but
do not use cold-weather oil for hard driving
or in warm weather, see page 283 for more
information on engine oil.
NOTE Synthetic oil is not used when the oil is
changed at the normal maintenance inter-
vals except at owner request and at addi-
tional charge.
\b
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.
\b Volvo recommends the use of snow tires
on all four wheels for winter driving, see
page 262.
\b 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

206 Fuel requirements
Deposit control gasoline (detergent
additives)
Volvo recommends the use of detergent gas-
oline to control engine deposits. Detergent
gasoline is effective in keeping injectors and
intake valves clean. Consistent use of deposit
control gasolines will help ensure good driva-
bility and fuel economy. If you are not sure
whether the gasoline contains deposit control
additives, check with the service station oper-
ator.
NOTE
Volvo does not recommend the use of
external fuel injector cleaning systems.
Unleaded fuelEach Volvo has a three-way catalytic converter
and must use only unleaded gasoline. U.S. and
Canadian regulations require that pumps deliv-
ering unleaded gasoline be labeled "UNLEA-
DED". Only these pumps have nozzles which
fit your vehicle\fs filler inlet. It is unlawful to dis-
pense leaded fuel into a vehicle labeled "unlea-
ded gasoline only". Leaded gasoline damages
the three-way catalytic converter and the
heated oxygen sensor system. Repeated use
of leaded gasoline will lessen the effectiveness of the emission control system and could result
in loss of emission warranty coverage. State
and local vehicle inspection programs will
make detection of misfueling easier, possibly
resulting in emission test failure for misfueled
vehicles.
NOTE
Some U.S. and Canadian gasolines contain
an octane enhancing additive called methyl-
cyclopentadienyl manganese tricarbonyl
(MMT). If such fuels are used, your Emission
Control System performance may be affec-
ted, and the Check Engine Light (malfunc-
tion indicator light) located on your instru-
ment panel may light. If this occurs, please
return your vehicle to a trained and qualified
Volvo service technician for service.
Gasoline containing alcohol and ethers,
"Oxygenated fuels"
Some fuel suppliers sell gasoline containing
"oxygenates" which are usually alcohols or
ethers. In some areas, state or local laws
require that the service pump be marked indi-
cating use of alcohols or ethers. However,
there are areas in which the pumps are
unmarked. If you are not sure whether there is
alcohol or ethers in the gasoline you buy, check
with the service station operator. To meet sea-sonal air quality standards, some areas require
the use of "oxygenated" fuel.
Volvo allows the use of the following "oxygen-
ated" fuels; however, the octane ratings listed
on page 207 must still be met.
Alcohol – EthanolFuels containing up to 10% ethanol by volume
may be used. Ethanol may also be referred to
as Ethyl alcohol, or "Gasohol".
Ethers – MTBE: Fuels containing up to
15% MTBE may be used.
MethanolDo not use gasolines containing methanol
(methyl alcohol, wood alcohol). This practice
can result in vehicle performance deterioration
and can damage critical parts in the fuel sys-
tem. Such damage may not be covered under
the New Vehicle Limited Warranty.

05 During your trip
Refueling05
209
CAUTION\b
Do not refuel with the engine running 2
.
Turn the ignition off or to position I. If the
ignition is on, an incorrect reading could
occur in the fuel gauge.
\b Avoid overfilling the fuel tank. Do not
press the handle on the filler nozzle
more than one extra time. Too much
fuel in the tank in hot weather conditions
can cause the fuel to overflow. Overfill-
ing could also cause damage to the
emission control systems. Emission controls
Three-way catalytic converter
\b
Keep your engine properly tuned. Certain
engine malfunctions, particularly 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 engine misfire, noticeable loss of
power or other unusual operating condi-
tions, such as engine overheating or back-
firing. A properly tuned engine will help avoid malfunctions that could damage the
three-way catalytic converter.
\b Do not park your vehicle over combustible
materials, such as grass or leaves, which
can come into contact with the hot exhaust
system and cause such materials to ignite
under certain wind and weather condi-
tions.
\b Excessive starter cranking (in excess of
one minute), or an intermittently firing or
flooded engine can cause three-way cata-
lytic converter or exhaust system over-
heating.
\b Remember that tampering or unauthorized
modifications to the engine, the Engine
Control Module, or the vehicle may be ille-
gal and can cause three-way catalytic con-
verter or exhaust system overheating. This
includes: altering fuel injection settings or
components, altering emission system
components or location or removing com-
ponents, and/or repeated use of leaded
fuel.
NOTE Unleaded fuel is required for vehicles with
three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxy-
gen content of the exhaust gases. Readings
are fed into a control module that continuously
monitors engine functions and controls fuel
injection. The ratio of fuel to air into the engine
is continuously adjusted for efficient combus-
tion to help reduce harmful emissions.
2
If the fuel filler cap is not closed tightly or if the engine is running\
when the vehicle is refueled, the Check Engine Light (malfunction indi\
cator lamp) may indicate a fault. However, your vehicle\fs
performance will not be affected. Use only Volvo original or approved fu\
el filler caps.

Introduction
Volvo recommends the use of Volvo trailer
hitches that are specially designed for the vehi-
cle.
NOTE
See page 282 for the maximum trailer and
tongue weights recommended by Volvo.
\b
Observe the legal requirements of the
state/province in which the vehicles are
\b 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:
\b Increase tire pressure to recommended
full. See the tire inflation tables beginning
on page 258.
\b When your vehicle is new, avoid towing
heavy trailers during the first 620 miles
(1,000 km).
\b Maximum speed when towing a trailer:
50 mph (80 km/h).
\b Engine and transmission are subject to
increased loads. Therefore, engine coolant
temperature should be closely watched when 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.
\b If the automatic transmission begins to
overheat, a message will be displayed in
the text window.
\b Avoid overload and other abusive opera-
tion.
\b Hauling a trailer affects handling, durabil-
ity, and economy.
\b It is necessary to balance trailer brakes
with the towing vehicle brakes to provide a
safe stop (check and observe state/local
regulations).
\b Do not connect the trailer\fs brake system
directly to the vehicle\fs brake system.
\b More frequent vehicle maintenance is
required.
\b Remove the ball and drawbar assembly
when the hitch is not being used.
\b Volvo recommends the use of synthetic
engine oil when towing a trailer over long
distances or in mountainous areas.
WARNING \b
Bumper-attached trailer hitches must
not be used on Volvos, nor should
safety chains be attached to the
bumper.
\b Trailer hitches attaching to the vehicle
rear axle must not be used.
\b Never connect a trailer\fs hydraulic
brake system directly to the vehicle
brake system, nor a trailer\fs lighting
system directly to the vehicle lighting
system. Consult your nearest author-
ized Volvo retailer for correct installa-
tion.
\b When towing a trailer, the trailer\fs 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.

NOTEDuring towing, ignition mode
II should be
used so that the lighting can be switched on.
CAUTION Vehicles with AWD (All Wheel Drive) with the
front wheels off the ground should not be
towed at speeds above 50 mph (70 km/h) or
for distances longer than 30 miles (50 km).
CAUTION
\b
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.
\b If the vehicle\fs battery is dead, do not
attempt to start the vehicle by pushing
or pulling it as this will damage the
three-way catalytic converter(s). The
engine must be jump started using an
auxiliary battery (see page 107).
\b If the vehicle is being towed on a flat bed
truck, the towing eyelets must not be
used to pull the vehicle up onto the flat
bed or to secure the vehicle on the flat
bed. Consult the tow truck operator.
Towing vehicles with front wheel drive/
All Wheel Drive
Volvo recommends the use of flat bed equip-
ment.
\b
If wheel lift equipment must be used,
please use extreme caution to help avoid
damage to the vehicle.
In this case, the
vehicle should be towed with the rear
wheels on the ground if at all possible.
\b If it is absolutely necessary to tow the vehi-
cle with the front wheels on the ground,
please refer to the towing information on
page 220.
CAUTION \b
Sling-type equipment applied at the
front will damage radiator and air con-
ditioning lines.
\b It is equally important not to use sling-
type equipment at the rear or apply lift-
ing equipment inside the rear wheels;
serious damage to the rear axle may
result.
\b If the vehicle is being towed on a flat bed
truck, the towing eyelets must not be
used to secure the vehicle on the flat
bed. Consult the tow truck operator.

06 Maintenance and specifications
Maintaining your car06
}}
225
Owner maintenance
Periodic maintenance requirements and inter-
vals are described in your vehicle\fs Warranty
and Service Records Information booklet.
The following points can be carried out
between the normally scheduled maintenance
services.
Each time the car is refueled:
\b
Check the engine oil level.
\b Clean the windshield, windshield wipers,
headlights, and tail lights.
Monthly:
\bCheck cold tire pressure in all tires. Inspect
the tires for wear.
\b Check that engine coolant and other fluid
levels are between the indicated "min" and
"max" markings.
\b Clean interior glass surfaces with a glass
cleaner and soft paper towels.
\b Wipe driver information displays with a soft
cloth.
\b Visually inspect battery terminals for cor-
rosion. Corrosion may indicate a loose ter-
minal connector, or a battery near the end
of its useful service life. Consult your Volvo
retailer for additional information.
As needed:Wash the car, including the undercarriage, to
reduce wear that can be caused by a buildup
of dirt, and corrosion that can be caused by salt
residues.
Clean leaves and twigs from air intake vents at
the base of the windshield, and from other pla-
ces where they may collect.
NOTE Complete service information for qualified
technicians is available online for purchase
or subscription at www.volvotechinfo.com.
Hoisting the vehicle
If a garage jack is used to lift the vehicle, the
two jack attachments points should be used.They are specially reinforced to bear the weight
of the vehicle. A garage jack can also be placed
under the front of the engine support frame.
Take care not to damage the splash guard
under the engine. Ensure that the jack is posi-
tioned so that the vehicle cannot slide off it.
Always use axle stands or similar structures.
If a two-post hoist is used to lift the vehicle, the
front and rear lift arm pads should be centered
under the reinforced lift plates on the inboard
edge of the sill rail (see illustration).
Emission inspection readiness
What is an Onboard Diagnostic System
(OBD II)?
OBD II is part of your vehicle\fs computerized
engine management system. It stores diagnos-
tic information about your vehicle\fs emission
controls. It can light the Check Engine light
(MIL) if it detects an emission control "fault." A
"fault" is a component or system that is not
performing within an expected range. A fault
may be permanent or temporary. OBD II will
store a message about any fault.
How do states use OBD II for emission
inspections?
Many states connect a computer directly to a
vehicle\fs OBD II system. The inspector can
then read "faults." In some states, this type of
