G026330
SRS warning light
As an enhancement to the three-point seat
belts, your Volvo is equipped with a Supple-
mental Restraint System (SRS). Volvo's SRS
consists of seat belt pretensioners, front air-
bags, side impact airbags, the occupant
weight sensor, and inflatable curtains. All of
these systems are monitored by the SRS con-
trol module. An SRS warning light in the instru-
ment panel (see the illustration) illuminates
when the ignition key is turned to position I, II,
or III, and will normally go out after approxi-
mately 7 seconds if no faults are detected in
the system.Where applicable, a text message will also be
displayed when the SRS warning light illumi-
nates. If this warning symbol is not functioning
properly, the general warning symbol illumi-
nates and either
SRS AIRBAG SERVICE
URGENT or SRS AIRBAG SERVICE
REQUIRED will be displayed.
WARNING
•If the SRS warning light stays on after
the engine has started or if it illuminates
while you are driving, have the vehicle
inspected by a trained and qualified
Volvo service technician as soon as
possible.
•Never try to repair any component or
part of the SRS yourself. Any interfer-
ence in the system could cause mal-
function and serious injury. All work on
these systems should be performed by
a trained and qualified Volvo service
technician.
WARNING
If your vehicle has been subjected to flood
conditions (e.g. soaked carpeting/standing
water on the floor of the vehicle) or if your
vehicle has become flood-damaged in any
way, do not attempt to start the vehicle or
put the key in the ignition before discon-
necting the battery (see below). This may
cause airbag deployment which could result
in personal injury. Have the vehicle towed to
a trained and qualified Volvo service tech-
nician for repairs.
Automatic transmission
Before attempting to tow the vehicle, use
the following procedure to override the
shiftlock system to move the gear selector
to the neutral position:
1. Switch off the ignition for at least
10 minutes and disconnect the battery.
2. Wait at least one minute.
3. Insert the key in the ignition and turn it
to position II.
4. Press firmly on the brake pedal.
5.
Move the gear selector from Park (P) to
the Neutral (N) position, see page 153,
for information on manually overriding
the shiftlock system.

* 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 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

more frequently and spray an anti-rust 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 217 for the location of
the washer fluid reservoir). This is impor-
tant since dirt is often splashed on the
windshield during winter driving, requiring
the frequent use of the washers and wip-
ers. Volvo Washer Solvent should be dilu-
ted 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 sol-
vent 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 turn-
ing the ignition key to position II. Many
electrical systems (the audio system, the
optional navigation system, power win-
dows, 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 (certain models only) provides electri-
cal 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 vol-
ume.
Before a long distance trip
It is always worthwhile to have your vehicle
checked at a trained and qualified Volvo serv-
ice technician before driving long distances.
Your trained and qualified Volvo service tech-
nician 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 checked2.
•Check condition of drive belts.
2To 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.

Starting a vehicle with keyless drive
G019410
Keyless drive makes it possible to unlock, start
and lock the vehicle without using a remote
key.
A start control is fitted in the ignition switch on
vehicles equipped with the optional keyless
drive. This control is used in the same way as
the ignition key to start the engine. See also
page 146 for general information on starting
the engine.
NOTE
A keyless drive remote key must be inside
the vehicle in order to start the engine.
1. Press the brake pedal (the clutch pedal
must also be fully depressed on models
with a manual transmission).
2. Press in the keyless drive start control and
turn it to position III.
NOTE
The vehicle is equipped with an autostart
function that makes it possible to start the
engine without holding the start control in
position III. Turn the start control to posi-
tion III and release it. The starter motor will
then operate automatically (for up to ten
seconds) until the engine starts.
Starting the vehicle with the ignition key
(remote key)
A vehicle with keyless drive can also be started
with the ignition key (if, for example, the battery
in the keyless drive remote key is weak). To do
so:
