A self-diagnostic system incorporated in the sensor monitors the SRS. If\
a fault is detected, the "SRS"
warning light will illuminate. the light is included in the warning/indi\
cator light cluster in the instrument
panel. Normally, the SRS warning light will be illuminated along with th\
e other warning/indicator lights
when the ignition key is turned to the ON position (position II), and \
go out a short time after the engine
has been started. Check that this light is functioning properly every ti\
me the car is started.
The following items are monitored by the diagnostic system:
l Sensor unit electronics integrity.
l Reserve energy supply.
l Diagnostic output circuit.
l System voltage.
l Integrity of system connectors.
l Mercury switch closure.
l Gas generator ignitor
WARNING! 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 Dealer for in\
spection as soon as possible.
ATTENTION! SRS VEHICLE!
THIS CAR IS EQUIPPED WITH A SUPPLEMENTAL RESTRAINT SYSTEM. TO PROVIDE
CONTINUED RELIABILITY, CERTAIN ELEMENTS OF THE SUPPLEMENTAL RESTRAINT
SYSTEM SHALL BE SERVICED OR REPLACED BY 1999. SEE OWNERS MANUAL FOR
FURTHER INFORMATION.

There is no maintenance to perform on the SRS yourself. The only periodi\
c maintenance recommended
on the SRS is that the air bag module and the sensor unit should be repl\
aced every ten years and that the
other components in the system (wiring, connectors, etc.) should also \
be inspected at this time. This
service must be performed by an authorized Volvo dealer.

To obtain best parking brake performance, the brake linings should be br\
oken in.
Stop 5-7 times from 30 mph (50 km/h), transmission in neutral, applyin\
g the parking brake with the
release button pressed in during the stop. The force must not lock the r\
ear wheels. If this happens,
release the brake enough to let the wheels rotate. Drive a mile between \
each stop to cool the brakes.
Check for proper parking brake operation.
Note: The brake lights are not illuminated when applying the parking bra\
ke. To warn traffic from
behind it is therefore advisable to depress the brake pedal slightly to \
illuminate the brake lights.
600 - 1,200 mile maintenance service
To ensure proper operation the car should be taken to a Volvo dealer bet\
ween the first 600 - 1,200 miles
(1,000 - 2,000 km) for a maintenance service. The oil in the engine, m\
anual transmission and rear axle
will then be changed. This is very important since the oil rapidly colle\
cts impurities during the break-in
period.
pg. 43 Driving economy, Shift indicator light
Economical driving does not necessarily mean driving slowly
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. Obs\
erve 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 instead of allowing the engine to idle for a prolo\
nged period. A cold engine uses
more fuel and is subject to increased wear.
l When possible avoid using the car 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 Do not exceed speed limit.
l Avoid carrying unnecessary items (extra load) in the car.
l Check tire pressures regularly (cold tires).
l Remove snow tires when threat of snow or ice has ended.
l Note that roof racks, ski racks, etc., increase air resistance and there\
by fuel consumption.

The power assist to the brakes functions only when the engine is running\
. When the car is moving
without the engine running the brake pedal pressure required to stop the\
car is increased 3- 4 times.
The brake pedal feels stiff and hard.
Disc brake noise: A slight-to-moderate amount of disc brake "squeal" is \
considered normal.
Air dam (front spoiler)
A non-factory air dam can negatively influence the normal flow of coolin\
g air to the front wheel brakes.
(See section titled "Wheels and Tires").
If one of the brake circuits should malfunction the red warning light wi\
ll come on
(See section titled "Warning Lights".)
The pedal stroke increases slightly and the pedal feels softer but the p\
edal pressure required does not
increase noticeably.
If the light comes on while driving and the brake pedal can be depressed\
further than normal, it is an
indication that one of the brake circuits is not functioning. Stop immed\
iately, open engine hood and
check brake fluid level.
Reservoir empty: do NOT drive. Tow car to shop for check/repair of brake\
system. Reservoir not empty:
proceed immediately and with caution to a Volvo dealer for an inspection\
of the brake system.
Severe strain on the brake system
The brakes will be subject to severe strain when driving in mountains or\
hilly areas. The speed is usually
low which means that the cooling of the brake is less efficient than whe\
n driving on level roads.
To reduce the strain on the brakes it is advisable not to use the brakes\
excessively.
Instead, shift into a lower gear and let the engine help with the brakin\
g. A good rule is to use the same
gear downhill as would be used ascending the same grade. For vehicles wi\
th automatic transmission use
position 2, or in some cases, 1.
