Range of the keyless drive remote key–5 ft
(1.5 meters)
This system makes it possible to unlock and
lock the vehicle without having to use the
remote key. It is only necessary to have a key-
less drive remote key in your possession to
operate the central locking system.
NOTE
The buttons on the keyless drive remote key
can also be used to lock and unlock the
vehicle, see page 122 for more information.
Both of the remote keys provided with the vehi-
cle have the keyless function, and additional
remotes can be ordered. The system can
accommodate up to six keyless drive remote
keys.

05 Locks and alarm
Alarm*
05

* Option/accessory, for more information, see Introduction.133 The alarm system
The alarm is automatically armed whenever the
car is locked with the remote key, or if a front
lock button is depressed.
When armed, the alarm continuously monitors
a number of points on the car. The following
conditions will trigger the alarm:
•The hood is forced open.
•The tailgate is forced open.
•A door is forced open.
•The ignition switch is tampered with
•An attempt is made to start the car with a
non-approved key (a key not coded to the
car's ignition).
•If there is movement in the passenger com-
partment (if the car is equipped with the
optional movement sensor).
•The car is lifted or towed (if the car is equip-
ped with the optional inclination sensor)
•The battery is disconnected (while the
alarm is armed).
•The siren is disconnected when the alarm
is disarmed.
The alarm indicator light
G020227
Alarm indicator light
The status of the alarm system is indicated by
the indicator light on at the top of the dash-
board (see the illustration):
•Indicator light off – the alarm is not armed
•The indicator light flashes every two sec-
onds – the alarm is armed
•The indicator light flashes rapidly before
the ignition is switched on – the alarm has
been triggered. The message
ALARM
TRIGGERED, CHECK CAR will also be
displayed.
•Fault in the alarm system: If a fault has
been detected in the alarm system, a mes-
sage will be shown in the information dis-
play. Contact your Volvo retailer to have
the alarm system inspected and repaired if
necessary.
Arming the alarm

Press the LOCK button on the remote key,
or press the central lock button on one of
the front doors with the door open. One
long flash of the turn signals will confirm
that the alarm is armed.
Disarming the alarm

Press the UNLOCK button on the remote
key or insert the key in the ignition1 to dis-
arm the alarm. Two short flashes from the
car's direction indicators confirm that the
alarm has been deactivated and that all
doors are unlocked.

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:
•Bring the engine to normal operating tem-
perature 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 kick-
down.
•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 con-
sumption.
•At highway driving speeds, fuel consump-
tion 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.
WARNING
Driving with the tailgate open: Driving with
the tailgate open could lead to poisonous
exhaust gases entering the passenger com-
partment. If the tailgate must be kept open
for any reason, proceed as follows:
1. Close the windows.
2. Set the ventilation system control to air
flow to floor, windshield and side win-
dows and the blower control to its high-
est setting.
Weight distribution affects handling
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.

143 Deposit control gasoline (detergent
additives)
Volvo recommends the use of detergent gas-
oline 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 driva-
bility and fuel economy. If you are not sure
whether the gasoline contains deposit control
additives, check with the service station oper-
ator.
NOTE
Volvo does not recommend the use of
store-bought fuel injector cleaning addi-
tives.
Unleaded fuel
Each Volvo has a three-way catalytic converter
and must use only unleaded gasoline. U.S. and
Canadian regulations require that pumps deliv-
ering unleaded gasoline be labelled "UNLEA-
DED". Only these pumps have nozzles which
fit your vehicle's filler inlet. It is unlawful to dis-
pense 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 effective-ness 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, pos-
sibly resulting in emission test failure for mis-
fueled 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 affec-
ted, and the Check Engine Light (malfunc-
tion indicator lamp) located on your instru-
ment 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 indi-
cating 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 sea-
sonal air quality standards, some areas require
the use of "oxygenated" fuel. Volvo allows theuse of the following "oxygenated" fuels; how-
ever, 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 "Gaso-
hol".
Ethers – MTBE: Fuels containing up to 15%
MTBE may be used.
MethanolDo not use gasolines containing methanol
(methyl alcohol, wood alcohol). This practice
can result in vehicle performance deterioration
and can damage critical parts in the fuel sys-
tem. Such damage may not be covered under
the New Vehicle Limited Warranty.
Fuel filler door
Press the button on the light switch panel (see
the illustration on page 63) with the ignition
switched off to unlock the fuel filler door.
Please note that the fuel filler door will remain
unlocked until the vehicle begins to move for-
ward. An audible click will be heard when the
fuel filler door relocks.
If you intend to leave your vehicle while it is
being refueled, this feature enables you to lock
the doors/tailgate while leaving the fuel filler
door unlocked.
