1 Fuel gauge

The fuel tank holds approximately 19.3 US gals. (73 liters). When the \
warning light comes on, there is approximately 1.8 US
gals. (8 liters) of fuel remaining in the tank. See "Refueling" for fu\
rther information.

2 Boost pressure gauge

(Turbo models only)
The boost pressure gauge is divided into sections. Black sections: The e\
ngine acts as a normally aspirated engine. Best fuel
economy is achieved while driving in this range. White section: The turb\
ocharger provides boost pressure.

3 Temperature gauge

The pointer should be approximately midway on the gauge face when drivin\
g. If the pointer approaches the red range repeatedly,
check coolant level. Do not drive the car with the pointer in the red ra\
nge. See "Coolant" section.

Brake fluid warning light
If the light comes on while driving or braking, this indicates that the \
brake fluid level is too low.
Stop immediately, open the hood and check the brake fluid level in the r\
eservoir (see section "Engine compartment" for reservoir
position)!
Canadian models are equipped with this warning light:

WARNING! If the level is below the MIN mark in either section of the res\
ervoir: DO NOT DRIVE. Tow the car to a Volvo
retailer and have the brake system checked and any leakage repaired.
pg. 1:5 Warning lights

If the TRACS (TRaction Control System) is manually disengaged with the\
switch on the dashboard, the warning light will come
on. This will also come on to indicate a TRAC's malfunction, and when th\
e brakes overheat, although it goes out again at the
normal temperature level. If the lamp remains on, the system should be c\
hecked by an authorized Volvo retailer. This lamp
should not be confused with the ON/OFF indicator lamp above the switch. \
See page 1:9 for additional information.


Anti-lock Brake System (ABS)
If the warning lamp lights up there is a malfunction of the ABS system (\
the standard braking system will however function). The
vehicle should be driven to a Volvo retailer for inspection.
See page 4:16 for additional information.
Canadian models are equipped with this warning light:



Coolant level sensor
If the light comes on while driving, the coolant level is low. The coola\
nt level in the expansion tank should be checked
immediately and topped off if necessary. The cooling system should be in\
spected by an authorized Volvo retailer.


Mode "W" engaged
The lamp will light up when the Winter/Wet mode is engaged or if gears "\
3" or "L" are selected.
If the warning lamp begins to flash , this means that there is a fault i\
n the automatic gearbox.
Contact your Volvo retailer.


Supplemental Restraint System (SRS)
If the light comes on (or stays on after the vehicle has started), the\
SRS diagnostic system has detected a fault. Drive to an

pg. 1:11 Clock, Ambient temperature sensor (certain models)

Resetting the clock

The digital clock can be reset by pressing one of the two buttons (A an\
d B) with a pointed object such as
the tip of a pen.
h = hours
m = minutes
Maintain the pressure on the buttons for more than four seconds to chang\
e the time more quickly.

Ambient temperature sensor

This sensor indicates the temperature slightly above the road surface. A\
n amber warning lamp (C) lights
up when the temperature is in the range of 23 - 35° F (-5 - +2° C\
). Please note that this lamp does not
indicate a fault with your car.
At low speeds or when the car is not moving, the temperature readings ma\
y be slightly higher than the
actual ambient temperature due to the heat generated by the engine.

Display alternatives

If buttons A and B are pressed down simultaneously, it is possible to sh\
ift between four different display
alternatives, as follows:

Press 1st time: 12 hour clock and °F
Press 2nd time: 24 hour clock and °F
Press 3rd time: 12 hour clock and °C
Press 4th time: 24 hour clock and °C

NOTE: If your battery has been disconnected, the display will default to\
the 24 hour clock and degrees
centigrade.

Current fuel consumption mpg (Canada: L/100 km)

Continuous information on current fuel consumption, calculated once per \
second. When the car is not
moving, the display shows "---".


Average fuel consumption Ø mpg (Canada: L/100km)

Average fuel consumption since the function was last reset. When the ign\
ition is switched off, the
average fuel consumption figure is stored in memory until it is reset us\
ing the button on the trip
computer control. pg. 1:14 Trip computer (certain models)

Ambient temperature

Shows the ambient temperature just above the road surface while driving.\
When the temperature is in the
range 23-36° F(-5 - +2° C), the ambient temperature sensor activ\
ates and amber warning light. Please
note that this light does not indicate a fault with your car. At low spe\
eds or when the car is not moving,
the temperature readings may be slightly higher than the actual ambient \
temperature due to the heat
generated by the engine.

compartment from outside. Do not leave the system in this mode for more \
than 10-15 minutes, since the
air inside the car will become stale and condensation will form on the w\
indows.

NOTE: To help maintain stable passenger compartment temperature when dri\
ving with the sun roof or
windows open, place the blower control in position "0" and adjust the de\
sired temperature manually.

l If the panel vents are open, a certain amount of air will always flow th\
rough, regardless of the position
the function dial is in. To increase the flow of air to either the floor\
or the windows, close the panel
vents. The outer vents can be opened to avoid mist on the side windows. \
l The panel vents may emit some condensation when the air conditioning is \
initially switched on and is
quite normal. This may occur if the ambient temperature and humidity are\
high.
l The sunlight sensor (located at the top center of the dashboard) shoul\
d not be covered in any way as
this could cause incorrect information to be sent to the ECC system.
l The air conditioning is momentarily disengaged during full-throttle acce\
leration.

Difficult weather conditions

When driving in very humid conditions, heavy rain, sleet, etc., it may b\
e better to use the manual rather
than the automatic setting to defrost the windows. Set the mode selector\
to "Defrost"
or "Defrost/
floor" and the fan speed to 3 or higher. Also shut the middle air vents.\


Faults in the ECC system

The REC and AC OFF lights will flash for approximately 20 seconds if a f\
ault is detected in the ECC
system.
If this flashing recurs the next time the system is switched on, the cli\
mate control unit should be checked
by an authorized Volvo retailer.

The airbag system includes gas generators (1) surrounded by the airbag\
s (2) and front seat belt
tensioners for both of the front seats (4). To deploy the system, the \
sensor (3) activates the gas
generators causing the airbags to be inflated with nitrogen gas. As the \
movement of the seat's occupants
compresses the airbags, some of the gas is expelled at a controlled rate\
to provide better cushioning.
Both seat belt tensioners also deploy, minimizing any seat belt slack.

The entire process, including inflation and deflation of the airbags, ta\
kes approximately two-tenths of a
second.
WARNING! When installing any optional equipment make sure that the SRS s\
ystem is not damaged.
Do not attempt to service any component of the SRS yourself. Attempting \
to do so may result in
serious personal injury. If a problem arises, take your car to the neare\
st authorized Volvo Retailer for
inspection as soon as possible.

A self-diagnostic system incorporated in the sensor monitors the SRS. Th\
is system does not, however,
monitor the SIPS airbags. If a fault is detected, the "SRS" warning ligh\
t will illuminate. The light is
included in the warning/indicator light cluster in the instrument panel.\
Normally, the SRS warning lamp
should light up when the ignition is switched on and should go out after\
10 seconds or when the engine
is started. Check that this light is functioning properly every time the\
car is started.

The following items are monitored by all the self-diagnostic system:
l Sensor unit
l Cable harness
l Gas generator ignitors
WARNING!
Never drive an SRS equipped car with your hands on the steering wheel pa\
d/airbag housing.
No objects, accessory equipment or stickers may be placed on, attached t\
o or installed near the SRS
cover in the center of the steering wheel, the SRS cover above the glove\
compartment or the area
affected by the airbag deployment.
If the SRS warning light stays on after the engine has started or if it \
comes on while you are driving,
drive the car to the nearest authorized Volvo retailer for inspection as\
soon as possible.

NOTE: The information on this page does not pertain to the Side Impact p\
rotection System airbags.

When are the airbags deployed?

The SRS system is designed to deploy during certain frontal or front-ang\
ular collisions, impacts, or
decelerations, depending in the crash severity, angle, speed, and object\
impacted. The SRS sensor is
designed to react to both the impact of the collision and the inertial f\
orces generated by it and to
determine if the intensity of the collision is sufficient for the airbag\
s to be deployed.

NOTE: The SRS system activates only once in a collision.

If the airbags have been deployed, we recommend the following:
Have the car towed to an authorized Volvo retailer. Even if it can be dr\
iven after an accident we do not
recommend driving the car with deployed airbags.
Have an authorized Volvo retailer replace the SRS system components.
Use only new, Genuine Volvo Parts when replacing SRS components (airbag\
s, seat belts, tensioners,
etc.)

When are the airbags NOT deployed?

Not all frontal collisions activate the SRS system. If the collision inv\
olves a non-rigid object (e.g., a
snow drift or bush), or a rigid, fixed object at a low speed, the SRS s\
ystem will not necessarily deploy.
Airbags do not normally deploy in a side impact collision, in a collisio\
n from the rear or in a rollover
situation. The amount of damage to the bodywork does not reliably indica\
te if the airbags should have
deployed or not.

Can the airbags deploy accidentally?

The SRS system is designed to deploy during certain frontal or front-ang\
ular collisions, impacts, or
decelerations, depending on the crash severity, angle, speed and object \
impacted. The SRS system has
its own diagnostic unit which continuously monitors and inspects the sys\
tem. Make a habit of checking

SIPS airbag decal*

SIPS airbag (front seats only)

As an enhancement to the structural Side Impact Protection System built \
into your car, your car is also
equipped with Side Impact Protection System (SIPS) airbags. The SIPS a\
irbag system consists of airbag
modules built into the sides of both front seat backrests (1), cables \
(2) from these modules to the
mechanical sensor units (3) and gas generators (4).
The SIPS airbag system is designed to help increase occupant protection \
in the event of certain side
impact collisions. The SIPS airbags are designed to deploy only during c\
ertain side-impact collisions,
depending on the severity, angle, speed, and point of impact. The airbag\
s are not designed to deploy in
all side impact situations.

NOTE: SIPS airbag deployment (one airbag) occurs only on the side of t\
he vehicle affected by the
impact.

* A SIPS airbag warning decal is located at the end of the instrument pa\
nel on the driver's side of the
car.
