section. Loads should be distributed so that capacity weight or 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).
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 257
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

consult your Volvo retailer.

charge more frequently and spray an antirust oil on the battery posts.
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 page 211 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.
135 06 Starting and driving
General information
Before a long distance trip
It is always worthwhile to have your vehicle checked by a trained and qualified Volvo service technician before
driving long distances. Your retailer or service technician 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 a trained and qualified Volvo service
ProCarManuals.com

technician 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.
1To prevent injury from contact with hot surfaces, do not inspect your vehicle's transmission fluid yourself. Have your vehicle's transmission fluid
level inspected by a qualified Volvo service technician.

Fuel requirements
Octane rating
MINIMUM
Volvo recommends premium for best performance, but using 87 octane or above will not affect engine reliability.
Volvo engines are designed to achieve rated horsepower, torque, and fuel economy performance using premium 91
octane fuel.
In demanding driving conditions, such as operating the vehicle in hot weather, towing a trailer, or driving for extended
periods at higher altitudes than normal, it may be advisable to switch to higher octane fuelRECOMMENDED
ProCarManuals.com

(91 or higher) or to change gasoline brands to fully utilize your engine's capacity, and for the smoothest possible
operation.
NOTE
When switching to higher octane fuel or changing gasoline brands, it may be necessary to fill the tank more than
once before a difference in engine operation is noticeable.
Deposit control gasoline (detergent additives)
Volvo recommends the use of detergent gasoline 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 drivability and fuel
economy. If you are not sure whether the gasoline contains deposit control additives, check with the service station
operator.
NOTE
Volvo does not recommend the use of store -bought fuel injector cleaning additives.
Unleaded fuel
Each Volvo has a three-way catalytic converter and must use only unleaded gasoline. U.S. and Canadian regulations
require that pumps delivering unleaded gasoline be labelled "UNLEADED". Only these pumps have nozzles which fit
your vehicle's filler inlet. It is unlawful to dispense leaded fuel into a vehicle labelled "unleaded 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
137 06 Starting and driving
Fuel requirements
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 affected, and the
Check Engine Light (malfunction indicator lamp) located on your instrument panel may light. If this occurs, please
return your vehicle to a trained and qualified Volvo service technician for maintenance.
Gasoline containing alcohol and ethers
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 indicating 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 seasonal air quality standards, some areas require the use of "oxygenated"
fuel. Volvo allows the use of the following "oxygenated" fuels; however, the octane ratings listed on this page must
still be met. Alcohol - Ethanol : Fuels 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.
