pg. 56 Break-in period, Fuel requirements
A new car should be broken -in

Refrain from utilizing your car's full driving potential during the first 1,200 miles (2,000 km) including the "kick -
down" function (automatic transmission).
NOTE - ENGINE OIL:
Although some oil consumption occurs during normal engine operation, more oil is consumed when the engine is new
as the internal parts generate higher friction while wearing-in to each other. From the time the engine is new until
the first service is performed, the oil consumption could be higher than normal. For this reason, it is especially
important to check the oil every time you refuel your car during this period. See page 114
.
In general, the rate of oil consumption depends on such factors as: engine temperature, length of trip, driving
conditions, oil viscosity and quality, engine speed and acceleration/deceleration.
Checking your engine oil level each time the car is refueled is one of the most important items you can perform to
help keep your car in good running order.

4th gear 70 mph (110 km/h)80 mph (130 km/h)
5th gear/overdrive 80 mph (130 km/h)95 mph (150 km/h)
Posted speed limits should not be exceeded.
Deposit control gasoline (detergent additives)
Volvo recommends the use of gasoline containing deposit control additives. These additives have shown to be efficient
in keeping injectors and intake valves clean. Consistent use of deposit control gasolines will help ensure good
driveability and fuel economy. If you are not sure whether the gasoline contains deposit control additives, check with
the service station operator.
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 labeled "UNLEADED". Only these pumps have nozzles which fit
your car's filler inlet. It is unlawful to dispense leaded fuel into a vehicle labeled "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 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 Malfunction Indicator Lamp located on your instrument panel may light. If this occurs, please return your
vehicle to an authorized Volvo retailer for service.
pg. 57 Fuel requirements, Refueling
Octane Rating

Volvo engines are designed for optimum performance on unleaded premium gasoline with an octane rating. AKI of 91,
or above. AKI (ANTI KNOCK INDEX) is an average of the Research Octane Number, RON, and the Motor Octane
Number, MON, (RON + MON/ 2).
The minimum octane requirement is AKI 87 (RON 91).
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 indicating use of alcohol 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 restrictions, some states require the use of "oxygenated" fuel in certain areas.
Volvo allows the use of the following "oxygenated fuels; however, the octane ratings listed on this page must still be
met.
Alcohol — Ethanol

Maintain correct tire pressure.
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.
If the wheels are rotated, they should be kept on the same side of the car so that they revolve in the same direction
as prior to rotation.
Hitting curbs or potholes can damage the tires and/or wheels permanently.
Flat spots
All tires become warm during use. After cooling, when the vehicle is parked, the tires have a tendency to distort
slightly, forming flat spots. These flat spots can cause vibrations similar to the vibrations caused by unbalanced wheels.
They do, however, disappear when the tire warms up. The degree to which the flat spots form depends on the type of
cord used in the tire. Remember that, in cold weather, it takes longer for the tire to warm up and consequently longer
for the flat spot to disappear.
CAUTION: The car must not be driven with wheels of different dimensions. The use of different size wheels can
seriously damage your car's transmission.
pg. 77 Wheels and tires (cont.)
Snow chains

Snow tire chains can be used on your Volvo with the following restrictions:
Snow chains should be installed on front wheels only. Use only Volvo approved snow chains.
Snow chains may be mounted on tire dimension 195/65R15. Tire dimension 205/55R16 requires a special type of
snow chain. Consult your Volvo retailer. Snow chains may not be used on 205/55R16 tires.
If accessory, aftermarket or "custom" tires and wheels are installed and are of a size different than the original tires
and wheels, chains in some cases CANNOT be used. Snow chains cannot be used on those turbo-charged models fitted
with all-season tires 225/50R16 or 225/45R17 or 225/40R18. Sufficient clearances between chains and brakes,
suspension and body components must be maintained.
Some strap -on type chains will interfere with brake components and therefore CANNOT be used.
Consult your Volvo retailer for additional snow chain information.
CAUTION:
Check local regulations regarding the use of snow chains before installing.
Always follow the chains manufacturer's installation instructions carefully. Install chains as tightly as possible and
re-tighten periodically.
Never exceed the chain manufacture's specified maximum speed limit. (Under no circumstances should that limit
be higher than 30 mph (45 km/h).
Avoid bumps, holes or sharp turns when driving with snow chains.
The handling of the vehicle can be adversely affected when driving with chains. Avoid fast or sharp turns as well
as locked wheel braking.
Snow tires, studded tires *
Tires for winter use:
Owners who live in or regularly commute through areas with sustained periods of snow or icy driving
conditions are strongly advised to fit suitable winter tires to help retain the highest degree of traction.
It is important to install winter tires on all four wheels to help retain traction during cornering, braking and
accelerating. Failure to do so could reduce traction to an unsafe level or adversely affect handling. Do not mix tires of
ProCarManuals.com

that a removed wheel can be reinstalled in its original position (as when changing over to winter tires/wheels).
CAUTION:
The car must not be driven with wheels of different dimensions or with a spare tire other than the one that came
with the car. The use of different size wheels can seriously damage your car's transmission.
pg. 83 Wheel changing (cont.)

Jack attachment
There is a jack attachment located in the center on each side of the car. Position the jack on the bar in the attachment
as shown in illustration A above and crank while simultaneously guiding the base of the jack to the ground. The base
of the jack must be flat on a level, firm, non-slippery surface. Before raising the car check that the jack is still
correctly positioned in the attachment. Raise the vehicle until both wheels on the side of the car where the jack is
attached are lifted off the ground. Unscrew the wheel bolts completely and carefully remove the wheel so as not to
damage the thread on the studs.
Installing the wheel
Clean the contact surfaces on the wheel and hub. Lift the wheel and place it on the hub. Make sure that you align the
wheel with the guide stud on the wheel hub prior to installation. Install the wheel bolts crosswise (see illustration) and
tighten by turning lightly clockwise. Lower the vehicle to the ground and alternately tighten the nuts to 81 ft. lbs. (110
Nm). Install the wheel cap (where applicable).

Correct tightening order for wheel bolts
WARNING!
The jack's attachment must engage the bar in the jack attachment (A). The car's weight must not rest on the jack's
attachment (B).
Be sure the jack is on a firm, level, non-slippery surface.
Never allow any part of your body to be extended under a car supported by a jack.
Use the jack intended for the car when replacing a wheel. For any other job, use stands to support the end of the
car being worked on.
Apply the parking brake, select position P (automatic transmission) or Reverse gear (manual transmission).
Block the wheels standing on the ground, use rigid wooden blocks or large stones.
The jack should be kept well-greased.
ProCarManuals.com

CAUTION: Correct tightening torque on wheel bolts must be observed. The wheel bolts should never be greased or
lubricated. The extended, chromed wheel bolts must not be used with steel rims, as they make it impossible to fit the
hub caps.
pg. 84 Spare tire
Temporary Spare (certain models)
The spare tire of your car is what is called a "Temporary Spare". It has the following designation: T115/70 R15 or
T125/90R15.
Recommended tire pressure (see decal on fuel filler flap) should be maintained irrespective of which position on the
car the Temporary Spare tire is used on.
In the event of damage to this tire a new one can be purchased from your Volvo retailer.
CAUTION: The car must not be driven with wheels of different dimensions or with a spare tire other than the one
that came with the car. The use of different size wheels can seriously damage your car's transmission.
WARNING!
Current legislation prohibits the use of the "Temporary Spare" tire other than as a temporary replacement for a
punctured tire. In other words, it must be replaced as soon as possible by a standard tire. Roadholding, etc., may be
affected with the "Temporary Spare" in use. Do not, therefore, exceed 50 mph (80 km/h).

Oil quality

Meeting API specification SG, SG/CD, SH or Energy Conserving (EC) II
For best fuel economy and engine protection, consult with your authorized Volvo retailer for recommended oils. Oil
with a different quality rating may not provide adequate engine protection. Synthetic oils 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 or for prolonged driving in mountainous areas.
Extra oil additives must not be used unless advised by an authorized Volvo retailer.
NOTE: SAE 15 W -40 oil should only be used in extreme operating conditions such as trailer towing in sustained
ambient temperatures over 104° F (40° C). However, SAE 10W -30 synthetic oil would be a better alternative in such
conditions.
SAE 15W-30 should not be used under normal operating conditions.
