6 Introduction
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 igniti\
on
key to position II (or start the engine), depress the brake pedal, pre\
ss 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 self-diagnostic test when the vehi\
cle first reaches the speed of approximately 12 mph (20 km/ h).
The brake pedal will pulsate several times and a sound may be audible fr\
om the ABS control module. This is normal.
Fuel filler door
Press the button on the light switch panel when the car is at a standsti\
ll 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 ("Chec\
k Engine" light) may indicate a fault.
Points to keep in mind
l Before you operate your vehicle for the first time, please familiarize y\
ourself with the new-engine oil consumption information on page
191. You should also be familiar with the information found in the chapters\
"Instruments and controls," and "Starting and driving."
l Information contained in the balance of the manual is extremely useful a\
nd should be read after operating the vehicle for the first time.
l The manual is structured so that it can be used for reference. For this \
reason, it should be kept in the vehicle for ready access.
l Do not export your Volvo to another country before investigating that co\
untry's applicable safety and emission control requirements. In
some cases it may be difficult or impossible to comply with these requir\
ements. Modifications to the emission control system(s) may
render your Volvo not certifiable for legal operation in the U.S., Canad\
a and other countries.
l All information, illustrations and specifications contained in this manu\
al are based on the latest product information available at the

eed will be erased from system memory) by
pressing RESET (C) for at least five seconds.
MILES TO EMPTY TANK
This function shows the approximate distance that can be driven on the f\
uel remaining in the tank. This calculation is
based on average fuel consumption during the last 20 miles (30 km) of \
driving and the amount of fuel remaining in
the tank when the reading was taken. When the driving distance on curren\
t fuel reserve is less than 12 miles (20 km),
"----" will be displayed in the information display.
AVERAGE
This value indicates fuel consumption since the last time the trip compu\
ter was reset (by pressing RESET, button C).
When the engine is switched off, information on fuel consumption is stor\
ed and remains in system memory until the
RESET (button C) is pressed again.

122 06 Starting and driving
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:
l 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.
l Whenever possible, avoid using the vehicle for driving short distances. \
This does not allow the engine
to reach normal operating temperature.
l Drive carefully and avoid rapid acceleration and hard braking.
l Use the transmission's Drive (D) position as often as possible and avo\
id using kickdown.
l Do not exceed posted speed limits.
l Avoid carrying unnecessary items (extra load) in the vehicle.
l Maintain correct tire pressure. Check tire pressure regularly (when tir\
es are cold).
l Remove snow tires when threat of snow or ice has ended.
l At highway driving speeds, fuel consumption will be lower with the air c\
onditioning on and the
windows closed than with the air conditioning off and the windows open. \
l Using the onboard trip computer's fuel consumption modes can help you le\
arn how to drive more
economically.
Other factors that decrease gas mileage are:
l Dirty air cleaner
l Dirty engine oil and clogged oil filter
l Dragging brakes
l Incorrect front end alignment
Some of the above mentioned items and others are checked at the standard\
maintenance intervals.
Avoid overheating the engine
Do not drive at engine speeds above 4,500 rpm if you tow a trailer in hi\
lly areas. This could cause the
engine oil to overheat.

CAUTION
l Engine damage will occur if water is drawn into the air cleaner.
l 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 sh\
orten the service life of these
components.
l Do not allow the vehicle to stand in water up to the door sills longer t\
han absolutely necessary. This
could result in electrical malfunctions.
l 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, t\
he following advice is worth
noting:
l Make sure that the engine coolant contains 50 percent antifreeze. Any ot\
her 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 an\
tifreeze must not be mixed.
l Volvo recommends using only genuine Volvo antifreeze in your vehicle's r\
adiator. Your Volvo retailer
stocks plenty of Volvo engine coolant to help protect your vehicle durin\
g cold weather.
l Try to keep the fuel tank well filled - this prevents the formation of c\
ondensation in the tank. In
addition, in extremely cold weather conditions it is worthwhile to add f\
uel line de-icer before refueling.
l The viscosity of the engine oil is important. Oil with low viscosity (t\
hinner oil) improves cold-weather
starting as well as decreasing fuel consumption while the engine is warm\
ing 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 239 for more information.
l The load placed on the battery is greater during the winter since the wi\
ndshield 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 there\
fore advisable to check the state
of
1Synthetic oil is not used when the oil is changed at the normal maintena\
nce intervals except at owner request and
at additional charge. Please consult your Volvo retailer.

charge more frequently and spray an antirust oil on the battery posts.
l Volvo recommends the use of snow tires on all four wheels for winter dri\
ving - see the chapter "Wheels
and tires."

l To prevent the washer fluid reservoir from freezing, add washer solvents\
containing antifreeze (see
page 193 for the location of the washer fluid reservoir). This is important sin\
ce 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 D\
own 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.
l 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:
l When the engine is not running, avoid turning the ignition key to positi\
on 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.
l 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 drain\
ed.
l The optional 12 volt socket in the cargo area provides electrical curren\
t even with the ignition switched
off, which drains the battery.
NOTE
l If the ignition is switched on, a warning message will be displayed in t\
he text window in the
instrument panel when the battery charge is low.
l An energy conserving function designed into the vehicle's electrical sys\
tem 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 p\
lugs 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\
:
l Check that engine runs smoothly and that fuel consumption is normal.
l Check for fuel, oil, and fluid leakage
l Have the transmission oil level checked1.
