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 temperature 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 (D)rive position as often as possible and avoid using kickdown.
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.

switched off when the vehicle is rolling. The brake pedal feels harder than usual.
Water on brake discs and brake pads affects braking
Driving in rain and slush or passing through an automatic car wash can cause water to collect on the brake discs and
pads. This will cause a delay in braking effect when the pedal is depressed. To avoid such a delay when the brakes are
needed, depress the pedal occasionally when driving through rain, slush, etc. This will remove the water from the
brakes. Check that brake application feels normal. This should also be done after washing or starting in very damp or
cold weather.
Severe strain on the brake system
The brakes will be subject to severe strain when driving in mountains or hilly areas, or when towing a trailer. Vehicle
speed is usually slower, which means that the cooling of the brakes is less efficient than when driving on level roads.
To reduce the strain on the brakes, shift into a lower gear and let the engine help with the braking. Do not forget that if
you are towing a trailer, the brakes will be subjected to a greater than normal load.
Anti-lock brakes (ABS)
The Anti-lock Braking System (ABS) helps to improve vehicle control (stopping and steering) during severe braking
conditions by limiting brake lockup. When the system "senses" impending lockup, braking pressure is automatically
modulated in order to help prevent lockup that could lead to a skid.
The system performs a self -diagnostic test when the engine is started and when the vehicle first reaches a speed
of approximately 12 m.p.h. (20 km/h).
The brake pedal will pulsate several times and a sound may be audible from the ABS control module. This is normal.
pg. 112 Starting and driving
Brake system
Electronic Brake Force Distribution (EBD)
EBD is an integrated part of the ABS system. EBD regulates the hydraulic pressure to the rear brakes to help provide
optimal braking capacity.
NOTE: To obtain optimal effect from the ABS system:
Keep constant pressure on the brake pedal.
Do not pump the brake pedal.
The switching of the ABS modulator will be audible and the brake pedal will pulsate during braking. Please be aware
that ABS does not increase the absolute braking potential of the vehicle. While control will be enhanced, ABS will not
shorten stopping distances on slippery surfaces.
If the warning lamp lights up there is a malfunction of the ABS system (the standard braking system will still function)
and the vehicle should be driven cautiously to a trained and qualified Volvo service technician for inspection.
WARNING!
If the BRAKE and ABS warning symbols light at the same time, there may be a problem in the brake system. If the
brake fluid level is normal in these circumstances, drive carefully to the nearest Volvo workshop to have the brake
system checked.
Emergency Brake Assistance - EBA
EBA is designed to provide full brake effect immediately in the event of sudden, hard braking. The system is activated
by the speed with which the brake pedal is depressed.
When the EBA system is activated, the brake pedal will go down and pressure in the brake system immediately

General description
The rear park assist system is designed to assist you when backing into parking spaces, garages, etc. It utilizes
ultrasound sensors located in the rear bumper to gauge distance, and provides an audible signal when the vehicle is
being backed close to another vehicle, object, or a person.
When is park assist active?
Front: the system is active from the time the engine is started until the car exceeds a speed of approximately 10 mph
(15 km/h).
Rear : the system is activated when reverse gear is selected. The indicator light in the button will light up.
When the system is actively working:
The audio system's volume will be reduced.
An intermittent signal will be audible from the speakers to indicate that you are approaching a person, object,
parked vehicle, etc. The signals begin when the distance between the bumper and the object is:
Rear : approximately 5 feet (1.5 meters).
Front : approximately 2.5 ft (0.8 meters)
At a distance of approximately 1 foot (30 cm), the signal will become constant.
Deactivating park assist, front/rear
Press the Exit button on the center control panel (see the illustration on page 51). PARK ASSIST DEACTIVATED,
ENTER TO ACTIVATE will be displayed.
Press Enter to reactivate the system.
NOTE:
Rear park assist : towing a trailer, carrying bicycles in a rear-mounted carrier, etc, could trigger the rear park assist
system's sensors.
NOTE: Rear park assist is deactivated automatically when towing a trailer if Volvo original connector wiring is used.
Front park assist : it may not be possible to combine auxiliary headlights. and front park assist since these lights
could trigger the system's sensors.
WARNING!
These systems are designed to be a supplementary aid when parking the vehicle. They are not, however, intended to
replace the driver's attention and judgement.
CAUTION!
In certain circumstances, the park assist system may give unexpected warning signals that can be caused by external
sound sources that use the same ultrasound frequencies as the system. This may include such things as the horns of
other vehicles, wet tires on asphalt, pneumatic brakes, motorcycle exhaust pipes, etc. This does not indicate a fault in
the system.

Towing a trailer
General information
Volvo recommends the use of Volvo trailer hitches that are specially designed for the vehicle.
Maximum trailer weights recommended by Volvo are:
Trailers without brakes : 1,540 lbs (700 kg).
Trailers with brakes: 2,000 lbs (900 kg) Observe the legal requirements of the state/province in which the vehicles
are registered.
The maximum recommended hitch tongue load is 165 lbs (75 kg).
All Volvo models are equipped with energy-absorbing shock-mounted bumpers. 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 consideration:
Increase tire pressure to recommended full. See the chapter "Wheels and tires."
When your vehicle is new, avoid towing heavy trailers during the first 620 miles (1,000 km).
Maximum speed when towing a trailer: 50 m.p.h. (80 km/h).
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 conditioner if the
temperature gauge needle enters the red range.
If the automatic transmission begins to overheat, a message will be displayed in the information display.
Avoid overload and other abusive operation.
Hauling a trailer affects handling, durability, 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 and drawbar assembly when the hitch is not being used.
ProCarManuals.com
Page 111 of 182
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's 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 a trained and qualified Volvo service technician for correct
installation.
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.
NOTE:
When parking the vehicle with a trailer on a hill, apply the parking brake before putting the gear selector in (P)ark,
or in reverse on models with a manual trans -

mission. Always follow the trailer manufacturer's recommendations for wheel chocking.
When starting on a hill, put the gear selector in (D)rive before releasing the parking brake.
If you use the manual (Geartronic) shift positions while towing a trailer, or if the vehicle is equipped with a manual
transmission, make sure the gear you select does not put too much strain on the engine (using too high a gear).
The drawbar assembly/trailer hitch may be rated for trailers heavier than the vehicle is designed to tow. Please
adhere to Volvo's recommended trailer weights.
Avoid driving with a trailer on inclines exceeding 15%.

Tire information placard: A placard showing the OE (Original Equipment) tire sizes, recommended inflation
pressure, and the maximum weight the vehicle can carry.
Tire Identification Number (TIN) : A number on the sidewall of each tire providing information about the tire
brand and manufacturing plant, tire size and date of manufacturer.
Inflation pressure : A measure of the amount of air in a tire.
Standard load: A class of P-metric or Metric tires designed to carry a maximum load at 35 psi [37 psi (2.5 bar) for
Metric tires]. Increasing the inflation pressure beyond this pressure will not increase the tires load carrying capability.
Extra load : A class of P-metric or Metric tires designed to carry a heavier maximum load at 41 psi [43 psi (2.9 bar)
for Metric tires]. Increasing the inflation pressure beyond this pressure will not increase the tires load carrying
capability.
kPa : Kilopascal, a metric unit of air pressure.
PSI: Pounds per square inch, a standard unit of air pressure.
B-pillar : The structural member at the side of the vehicle behind the door.
Bead area of the tire : Area of the tire next to the rim.
Sidewall of the tire: Area between the bead area and the tread.
Tread area of the tire : Area of the perimeter of the tire that contacts the road when mounted on the vehicle.
Rim: The metal support (wheel) for a tire or a tire and tube assembly upon which the tire beads are seated.
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.
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.
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 inflation 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 inflation table in this chapter.
Cold tires : The tires are considered to be cold when they have the same temperature 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 design 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 equipment. When towing, trailer hitch tongue load
is also part of cargo weight.
NOTE: For trailer towing information, please refer to the section "Towing a trailer" on page 120
.
Permissible axle weight
The maximum allowable weight that can be carried by a single axle (front or rear). These numbers are shown on the
Federal/Canadian Motor Vehicle Safety Standards (FMVSS/ CMVSS) label. The total load on each axle must never
exceed its maximum permissible weight.
ProCarManuals.com
Page 120 of 182
Gross vehicle weight (GVW)
The vehicle's curb weight + cargo + passengers.
NOTE:
The location of the various labels in your vehicle can be found on page 188.
A table listing important weight limits for your vehicle can be found on page 189.
Steps for Determining Correct Load Limit
(1) Locate the statement ''the combined weight of occupants and cargo should 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 kilograms 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. passengers 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 the vehicle. That weight may not safely
exceed the available cargo and luggage load capacity calculated in Step 4.
(6) If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult this
manual
1 to determine how this reduces the available cargo and luggage load capacity of your vehicle.
WARNING!
Exceeding the permissible axle weight, gross vehicle weight, or any other weight rating limits can cause tire
overheating resulting in permanent deformation or catastrophic failure.
Do not use replacement tires with lower load carrying capacities than the tires that were original equipment on the
vehicle because this will lower the vehicle's GVW rating. 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 between 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 the 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 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,
maintenance practices and differences in road characteristics and climate.
TRACTION
The traction grades, from highest to lowest, are AA, A, B, and C, as measured under controlled conditions on specified
government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. The traction

Operation in temperate climates
Incorrect viscosity oil can shorten engine life. Under normal use when temperatures do not exceed 86° F (30° C), SAE
5W -30 will provide good fuel economy and engine protection. See the viscosity chart.
Extreme engine operation
Synthetic oils meeting SAE 10W -30 and complying with oil quality requirements are recommended for driving in
areas of sustained temperature extremes (hot or cold), when towing a trailer over long distances, and for prolonged
driving in mountainous areas.
American Petroleum Institute (API) symbol
The API Service Symbol "donut" is divided into three parts:
The upper section describes the oil's performance level.
The center identifies the oil's viscosity.
The lower section indicates whether the oil has demonstrated energy-conserving properties in a standard test in
comparison to a reference oil.
pg. 192 Specifications
Engine specifications
Charge air cooler (Intercooler)
Turbocharged engines employ a turbo-compressor to force air into the engine inlet manifold and a charge air cooler to
cool the compressed inlet air. The resulting increase in air flow raises pressure in the intake manifold and increases
engine power over that developed by the normally-aspirated engine. The charge air cooler (which resembles a radiator)
is located between the turbo-compressor and inlet manifold.
Fuel system
The engine is equipped with a multiport fuel injection system.
