Volvo 1990 240 Model

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.
VOLVO

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.

l Avoid using automatic transmission kick-down feature unless necessary.

Other factors which decrease gas mileage are:
l Worn or dirty spark plugs
l Incorrect spark plug gap
l Dirty air filter
l Incorrect valve clearance
l Incorrect idle speed
l Dirty engine oil and clogged oil filter
l Dragging brakes
l Incorrect front end alignment
l Low tire pressure

Shift indicator light

(manual transmission models only)

The Volvo shift indicator light (S.I.L.) is a device designed to help \
you get even better gas mileage from
your Volvo car. Studies have shown that the best fuel economy is obtaine\
d by shifting gears at low
engine rpm and high relative engine load. The Volvo S.I.L. is calibrated\
to show you when to shift for
improved mileage without sacrificing smooth acceleration .

Use of the S.I.L. is simple. Shift to next higher gear as soon as the li\
ght comes on. You may find after
using the S.I.L. for some time that your natural shifting rhythm will ad\
apt to the S.I.L.'s suggestion.
Some drivers may even shift before the light comes on.
Obviously, there will be times when you need to shift later than the lig\
ht would indicate (for example,
when climbing hills or trailer towing). Using the light regularly, howe\
ver, should result in a mileage
improvement of six percent or more, depending on how you normally drive.\


Programming instructions for shift indicator

If the current supply to the control unit is cut (battery disconnected)\
, the control unit will have to be re-
programmed as the control unit memory will be erased.
Drive the car in each gear (first gear not necessary) for approximatel\
y 8 seconds.
The gear change indicator light will flicker once (0.5 seconds), as ea\
ch gear is programmed.

Note: Remove foot completely from the clutch pedal after each gear chang\
e when programming the
control unit.
pg. 44 Starting the engine
To start the engine;

1 Enter the car and check that the seat is adjusted properly. Make sure \
that the brake (and clutch) pedal
can be depressed completely. Move the seat closer if necessary.
2 Fasten the seat belt.
3 Apply the parking brake if not already set. Depress the brake pedal wi\
th your right foot.
4 Place the gear selector lever in neutral (position N or P, automatic \
transmission).
5 Depress the clutch pedal (manual transmission).
6 Without touching the accelerator pedal turn the ignition key to starti\
ng position. Release the key as
soon as the engine starts.

Avoid repeated short attempts to start (fuel is injected every time the\
starter is engaged when engine is
cold).
Allow the starter to operate for a longer time (but not more than 15-20\
seconds).
Do not race a cold engine immediately starting.

Engine warm-up-initial driving procedure

Experience shows that engines in vehicles driven short distances are sub\
ject to abnormally rapid wear
because the engine never reaches normal operating temperature.
It is therefore beneficial to reach normal operating temperature as soon\
as possible by driving with a
light foot on the accelerator pedal.
Warning: Always open the garage doors fully before starting the engine i\
nside the garage to ensure
adequate ventilation. The exhaust gases contain carbon monoxide, which i\
s invisible and odorless but
very poisonous.

Shift positions

P park D drive
R reverse 2 intermediate
N neutral 1 low

The gear selector can be moved freely between D and 2. Selections of oth\
er positions are obtained by
depressing the selector knob prior to moving the selector.
Depressing the selector knob slightly allows selection of positions N an\
d 1 .
Depressing the selector knob fully allows selection of positions R and P\
. This is also necessary when
initially bringing the selector out of position P .
Depressing the selector knob fully thus permits shifting freely between \
all positions.

P Park
Use this position when parked with the engine running or stopped.
Never use P while car is in motion.
The transmission is mechanically locked in position P. Also use the park\
ing brake when parking on
grades for added safety.

R Reverse
Never use R while car Is moving forward.

N Neutral
Neutral position = no gear is engaged. Use parking brake.

D Drive
D is the normal driving position. Upshift and downshift of the forward g\
ears occurs automatically and is
governed by acceleration and vehicle speed.

2 Intermediate position
Upshift and downshift of first two gears (low and intermediate) occurs\
automatically.
No upshift to 3rd (top) gear occurs.
Position 2 may be used to obtain forced downshift to 2nd gear for increa\
sed engine braking effect.
Position 2 can also be used...
l for relatively slow highway driving.
l for city driving.
l when driving on mountain roads where precise speed control is desirable.\

l for passing.

1 Low position
If position 1 is selected when driving at high speeds, 2 is engaged firs\
t and 1 when the speed has
dropped to approx. 30 mph (50 km/h).
NOTE: No upshift once 1 is
engaged.

Use position 1 to select low gear with no upshift. Use for instance, whe\
n ascending and descending steep
grades.
CAUTION:
l Never select P or R while the car is in motion.
l When initially selecting D, 2, 1 or R, your right foot should press firm\
ly on the brake and the engine
must be idling.
l Never downshift to 2 or 1 at speeds above 75 mph (125 km/h)*.
*Always observe local speed limits!

symbol.
Disengaging 4th gear

The transmission will engage 4th gear automatically after upshifting thr\
ough first, second and third gears
unless the disengagement button on the side of the gear knob is pushed. \

When the button is pushed to disengage 4th gear, the transmission operat\
es as a 3-speed unit. If the
button is pushed while 4th gear is engaged, then a downshift to 3rd gear\
will occur. The transmission,
then, cannot upshift to 4th gear until the button is pushed again. As a \
reminder, when 4th gear is
disengaged, the indicator light (
) in the instrument panel is illuminated.
Be aware that, if 4th gear is disengaged (reminder light illuminated) \
when the engine is switched off, the
transmission will revert automatically to 4-speed operation (reminder l\
ight not illuminated) when the
engine is restarted.

Disengage 4th gear (reminder light illuminated) when:
* towing a trailer
* driving on hilly roads where precise speed control is desired.

Kick-down

Automatic down-shift to a lower gear is achieved by depressing the throt\
tle pedal fully and briskly.
An up-shift will be achieved when approaching the top speed for a partic\
ular gear or by releasing the
throttle pedal slightly.
Kick-down can be used for maximum acceleration or when passing at highwa\
y speeds.

1. Enter the car and check that the seat is adjusted properly. Make sure\
that the brake pedal can be
depressed completely. Move the seat closer if necessary.
2. Fasten the seat belt.
3. Apply the parking brake if not already set. Depress the brake pedal w\
ith your right foot.
4. Place the gear selector in Park (or neutral).
5. Without touching the accelerator pedal, turn the ignition key to the \
starting position. Release the key
as soon as the engine starts.
6. Select the desired gear. There is a slight delay before the gear enga\
ges which is most notable when
selecting Reverse. Do not accelerate until you have felt the gear engage\
!
Note: Too-rapid acceleration immediately after selecting a gear will cau\
se harsh engagement and
premature transmission wear.

7. Release parking brake, then foot brake, and accelerate. To stop the c\
ar release the accelerator and
apply the brakes with your right foot.

It is not necessary to move the gear selector as the transmission will d\
ownshift automatically.
When idling for extended periods of time, select position N to prevent u\
nnecessary heating of the
transmission.
WARNING! Always place gear selector in Park and apply parking brake befo\
re leaving vehicle. Never
leave car unattended with engine running.
