1990 VOLVO 240 warning light

Volvo 1990 240 Model

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.

pg. 76 Replacing bulbs
Replacing bulbs

The replacement of bulbs in the various lighting units is shown on the f\
ollowing pages. Make sure when
installing bulbs, that the guide pin on the socket fits into its corresp\
onding recess.
When installing bulbs, do not touch the glass with your fingers. The rea\
son for this is that grease, oil or
any other impurities can be carbonized onto the bulb and damage the refl\
ector.
Use bulbs of correct type and voltage. Failure to do so could activate t\
he bulb failure warning light.



Replacing headlight bulbs

Working inside the engine compartment, separate the socket contact from \
the bulb holder (1). Unscrew
and remove the bulb holder retaining ring (2) Pull out the bulb holder\
assembly, and replace it as a unit
(3).
Installation is the reverse of removal.

Check headlight alignment.

dealer.

Condition: Starter fails to operate (or operates very slowly)
Possible cause Correction
Weak battery or dead cell. With the starting (ignition) switch in the "Driving"
or "On" position, check to see if the warning lights
on the dashboard come on and if they stay on when
the starter is engaged. If the lights do not come on or
if they go off when the starter is engaged, the battery
is discharged or see below.
Loose or corroded battery cable terminals. Check battery terminals and clamps. Clean or
replace if necessary. Check that the starter cable is
secure at its terminals.
The ground strap, which connects the battery
negative (-) terminal to the engine, should also be
checked for corrosion or looseness.
Open circuit between starting (ignition) switch
and starting (ignition) switch terminal on
starter. The circuit is closed if a clicking sound is heard
from the starter when it is engaged. If no clicking
sound is heard, check that the blue wire at the starter
is secure. If still no clicking sound is heard, the
starting (ignition) switch or the wire is defective.
Starter motor defective. If the above checks have been performed, and no
fault is evident, the starter may be defective. NOTE:
In this case the headlight intensity will not dim when
the starter is engaged.
