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 116-117.
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.

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 car for driving short distances. This does not allow the engine to reach normal
operating temperature.
Drive carefully and avoid rapid acceleration and hard braking.
Do not exceed speed limit.
Avoid carrying unnecessary items (extra load) in the car.
Maintain correct tire pressure. Check tire pressure regularly (check when tires are cold).
Remove snow tires when threat of snow or ice has ended.
Note that trunk-mounted luggage racks increase air resistance and thereby fuel consumption.
Avoid using automatic transmission kickdown feature unless necessary.
Avoid using the air conditioning when it is not required. When engaged, the air conditioner's compressor places an
additional load on the engine. However, please note that fuel consumption is lower with the air conditioning on than it
is when driving with the air conditioning switched off and the windows down.
If your car is equipped with the optional Trip Computer, utilizing the fuel consumption modes can help you "learn"
how to drive more economically.
Other factors which 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 Service intervals.
NOTE : (D)rive or 5th gear (manual transmissions) should be used as often as possible to help improve fuel economy.
pg. 64 Starting the Engine
Starting and stopping
1. Fasten the seat belt.
WARNING!
Before starting, check that the seat, steering wheel and mirrors are adjusted properly. Make sure the brake pedal can
be depressed completely. Move the seat closer if necessary. Refer to section "front seats".
2. Apply the parking brake, if not already set. The gear selector (automatic transmission) is locked in the (P)ark
position (SHIFT LOCK).
Manual transmission: the clutch must be fully depressed.
3. Without touching the accelerator pedal, turn the ignition key to the starting position*. Allow the starter to operate
for up to 10 seconds. Release the key as soon as the engine starts. If the engine fails to start, repeat step 3.
For cold starts at altitudes above 6000 ft (1800 meters), depress the accelerator pedal halfway and turn the key to the
starting position. Release the pedal slowly when the engine starts.
4. To release the gear selector from the (P)ark position (automatic transmission), the ignition key must be in position II

and the brake pedal must be depressed. See page 101 for instructions on manually releasing the SHIFTLOCK
system.
Do not race a cold engine immediately after starting. Oil flow may not reach some lubrication points fast enough to
prevent engine damage.
NOTE: (Automatic transmission only)
Your car is equipped with a KEYLOCK system. When the engine is switched off, the gear selector must be in the
( P )ark position before the starting key can be removed from the ignition switch.
5. Select the desired gear. The gear engages after a slight delay (automatic transmission) which is especially noticeable
when selecting R.
CAUTION : (Automatic transmission only)
The engine should be idling; never accelerate until after you feel the gear engage! Too rapid acceleration immediately
after selecting a gear will cause harsh engagement and premature transmission wear.
NOTE : Selecting P or N (automatic transmission) when idling at a standstill for prolonged periods of time will help
prevent overheating of transmission oil.
WARNING!
Always place the gear selector (automatic transmission) in Park and apply the parking brake before leaving the
vehicle. Never leave the car unattended with the engine running.
Always open the garage doors fully before starting the engine inside a garage to ensure adequate ventilation. The
exhaust gases contain carbon monoxide, which is invisible and odorless but very poisonous.
CAUTION:
Never race the engine immediately after starting. Oil flow may not reach some lubricating points fast enough to
prevent engine damage.
Do not race the engine just prior to switching off!
* If the key is left in the Drive position (position II) for more than 30 seconds, it must be turned to position 0 and then
turned to the Start position (position III) again in order to start the car. See page 21
for ignition key positions.
pg. 65 Manual transmission
Shift positions
ProCarManuals.com

Depress the clutch pedal completely when changing gears*.
Remove your foot from the clutch pedal while driving.
Overdrive (5th gear) should be used as often as possible to help improve fuel economy. This gear can be engaged at
speeds above approx. 50 mph (80 km/h).
CAUTION: Follow the shift pattern indicated on the gear shift knob when shifting up (e.g., do not shift directly from
2nd to 5th gear) to help avoid excessive wear on the transmission.
Engaging reverse gear
The gear lever must first be moved to neutral in order to engage reverse gear.
CAUTION: Be careful that you do not inadvertently engage reverse while moving forward.
* Clutch interlock (manual transmission only)
The clutch must be fully depressed before you can start your car. If the clutch is not depressed, it will not be possible
to start the engine.
pg. 66 Automatic transmission
P (Park)
ProCarManuals.com

Use this position when starting the engine or parking the car.
Never use P while the car is in motion.
The parking brake should be set whenever the car is parked.
The gear selector is mechanically locked in the P position (SHIFTLOCK). To release the gear selector from this
position, the engine must be running (or the ignition key must be in position II) and the brake pedal must be
depressed.WARNING! Never leave the car unattended when the engine is running. If, by mistake, the gear selector is moved
from P, the car may start moving.
R (Reverse)
Never engage R while the car is moving forward.
N (Neutral)
Neutral - no gear engaged. Use the parking brake.
D (Drive)
D is the normal driving position and should be used as often as possible to help improve fuel economy. The car should
not be moving when shifting from R to the D position.
4 (Intermediate gear)
The transmission will shift automatically between gears 4, 3, 2 or 1 from this position. The transmission cannot shift
up to (D) from fourth gear.
3 (Intermediate gear)
The transmission will shift automatically between gears 3, 2 and 1 from this position. The transmission cannot shift
up to fourth gear of (D)rive from third gear.
L (Low gear)
The transmission is locked in gears 1 and 2 when the selector is in this position.
NOTE:
Gears 4, 3, or L can be used if you are driving in a mountainous area, towing a trailer or to increase engine braking
effect.
The transmission has a built-in limiter designed to help prevent excessive engine speeds (high rpm) when gears 4, 3
or L are selected.
Automatic transmission - adaptive system
ProCarManuals.com

The automatic transmission is controlled by an adaptive control system that constantly monitors the way in which the
transmission functions. It senses and adapts each gear shift for optimal performance. The system also monitors your
particular driving style and adapts gear shifting accordingly.

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 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.
WARNING!
The jack's attachment must engage the bar in the jack attachment (see inset illustration above). The car's weight must
not rest on the jack 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.
NOTE: To avoid excessive wear and the necessity of rebalancing, mark and reinstall wheels in the same location and
position as before removal. To lessen the chance of imbalance, each wheel hub is equipped with a guide stud to ensure
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. 87 Wheel changing
WARNING!
The jack's attachment must engage the bar in the jack attachment (A). The car's weight must not rest on the jack
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 side 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.
Installing the wheel
ProCarManuals.com

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 bolts to 100 ft. lbs.
(130 Nm). Install the wheel cap (where applicable).
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.
Correct tightening order for wheel bolts
pg. 88 Spare tire
Temporary Spare (certain models)
The spare tire in your car is called a "Temporary Spare". It has the following designation: T125/90 R15.
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).
