General information
Shiftlock (automatic transmission)
When your car is parked, the gear selector is locked in the Park ( P) position. To release the selector from this position,
turn the ignition key to position II (or start the engine), depress the brake pedal, press the button on the front side of the
gear selector and move the selector from Park ( P).
Keylock (automatic transmission)
When the ignition is switched off, the gear selector must be in the Park ( P) position before the key can be removed
from the ignition switch.
Anti-lock Brake System (ABS)
The ABS system in your car performs a selfdiagnostic test when the vehicle first reaches the speed of approximately
12 mph (20 km/h). The brake pedal will pulsate several times and a sound may be audible from the ABS control
module. This is normal.
Fuel filler door
Press the button on the light switch panel when the car is at a standstill to open the fuel filler door.
Fuel filler cap
After refueling, close the fuel filler cap by turning it clockwise until it clicks into place. If this cap is not closed tightly
or if the engine is running when the car is refueled, the Malfunction Indicator Lamp ("Check Engine" light) may
indicate a fault.
Points to keep in mind
Before you operate your vehicle for the first time, please familiarize yourself with the new-engine oil consumption
information on page 189
. You should also be familiar with the information found in the chapters "Instruments and
controls," and "Starting and driving."
Information contained in the balance of the manual is extremely useful and should be read after operating the
vehicle for the first time.
The manual is structured so that it can be used for reference. For this reason, it should be kept in the vehicle for

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 Drive ( D) 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.
Note that roof racks, ski racks, etc, increase air resistance and also fuel consumption.
At highway driving speeds, fuel consumption 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.
Weight distribution affects handling
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 any reason, proceed as follows:
Close the windows
Set the ventilation system control to air flow to floor, windshield and side windows and the blower control to its
highest setting.
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 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, roadholding
Vehicle 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 distributed
so that capacity weight

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).
Take particular care when driving through flowing water.
Clean the electrical connections for trailer wiring after driving in mud or water
When driving through water, maintain low speed and do not stop in the water.
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
Engine damage will occur if water is drawn into the air cleaner.
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 shorten the service life of these components.
Do not allow the vehicle to stand in water up to the door sills longer than absolutely necessary. This could result
in electrical malfunctions.
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, 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). See section "Coolant". The use of "recycled" antifreeze
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. Your Volvo retailer stocks plenty
of Volvo engine coolant to help protect your vehicle during cold weather.
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 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 decreasing fuel consumption while the engine is warming 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 231
for more information.
The load placed on the battery is greater during the winter since the windshield 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 therefore advisable to check the state of
1 Synthetic oil is not used when the oil is changed at the normal maintenance intervals except at owner request and at additional charge. Please
consult your Volvo retailer.

General information
charge more frequently and spray an antirust oil on the battery posts.
ProCarManuals.com

Volvo recommends the use of snow tires on all four wheels for winter driving - see the chapter "Wheels and tires."
To prevent the washer fluid reservoir from freezing, add washer solvents containing antifreeze (see age 188 for the
location of the washer fluid reservoir). 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.
NOTE
Avoid using de -icing sprays as they can cause damage to the locks.
Conserving electrical current
Keep the following in mind to help minimize battery drain:
When the engine is not running, avoid turning the ignition key to position II. Many electrical systems (the audio
system, the optional navigation system, power windows, etc) will function with the ignition key in position I. This
position reduces drain on the battery.
Please keep in mind that using systems, accessories, etc that consume a great deal of current when the engine is not
running could result in the battery being completely drained.
The optional 12-volt socket in the cargo area provides electrical current even with the ignition switched off, which
drains the battery.
NOTE
If the ignition is switched on, a warning message will be displayed in the text window in the instrument panel
when the battery charge is low.
An energy conserving function designed into the vehicle's electrical system will switch off certain functions or
reduce the load on the battery by, e.g., reducing the audio system's volume.
Before a long distance trip
It is always worthwhile to have your vehicle checked at a Volvo retailer 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 checked1.
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 your Volvo retailer only.
Check all lights, including high beams.
Reflective warning triangles are legally required in some states/provinces.
Have a word with your Volvo retailer 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.

the amount of cargo
See the chapter "Wheels and tires" for more detailed information.
Before loading the car, turn off the engine, and apply the parking brake when loading or unloading long objects. The
gear selector can be inadvertently knocked out of position by long cargo, causing the car to move.
Keep the following in mind when loading the vehicle:
Load the cargo in the cargo area against the rear seat backrest.
Load heavy cargo as low as possible.
Center wide loads.
Secure all cargo with restraining straps anchored to the load securing eyelets.
Cover sharp edges on the load.
Seats can be folded down and head restraints removed to extend the cargo compartment. See page 101.
WARNING
Remember that an object weighing 44 lbs (20 kg) produces a force of 2,200 lbs (1,000 kg) in a head-on collision
at 30 m.p.h. (50 km/h)!
When the rear backrest(s) are folded down, the vehicle should not be loaded to a level higher than 2 in. (5 cm)
below the upper edge of the rear side windows. Objects placed higher than this level could impede the function of
the Volvo Inflatable Curtain.
Load carriers (accessory)
Load carriers are available as Volvo accessories. Follow the installation instructions supplied with the load carriers.
Observe the following points when using load carriers:
To avoid damaging your car and to achieve maximum safety when driving, we recommend using the load carriers
that Volvo has developed especially for your car.
Volvo-approved removable roof racks are designed to carry the maximum allowable roof load for this vehicle: 165
lbs (75 kg).
For Non-Volvo roof racks, check the manufacturer's weight limits for the rack.
Never exceed the rack manufacturer's weigh limits and never exceed the maximum rated roof load of 165 lbs (75
kg).
Avoid single-point loads. Distribute loads evenly.
Place heavier cargo at the bottom of the load.
Secure the cargo correctly with appropriate tie-down equipment.
Check periodically that the load carriers and load are properly secured.
Remember that the car's center of gravity and handling change when you carry a load on the roof.
The car's wind resistance and fuel consumption will increase with the size of the load.
Drive smoothly. Avoid rapid starts, fast cornering and hard braking.
