Safety Compliance Sticker

Dear Porsche Owner

A lot has gone into the manufacture of your

Porsche, including advanced engineering

techniques, rigid quality control and de-

manding inspections. These engineering
and safety features will be enhanced by
you...

the safe driver...

who knows his car and all controls,

who maintains his vehicle properly,

who uses his driving skills wisely.

The Safety Compliance Sticker is your as­surance that your Porsche complies with all
Federal Motor Vehicle Safety Standards
which were in effect at the time the vehicle
was manufactured. It is located on the door­sill on the driver's side.

The sticker also shows the month and year
of production and the vehicle identification
number of your car (perforations) as well as
the Gross Vehicle Weight Rating and the

Gross Axle Weight Rating.

You will find helpful hints in this manual on
how to perform most of the checks listed on
the following page. If in doubt, have these
checks performed by your Porsche dealer.

7

Before going on a trip... In the drivers seat... On the highway...

1 - Be sure tires are inflated correctly.Look

for bruises and tire wear.

2 - See that wheel bolts or nuts are not

loose or missing.

3- Check engine oil level, add if neces-

sary. Make it a habit to have engine oil
checked with every second fuel filling.

4 - Check coolant level to assure sufficient

engine cooling.

5 - Be sure you have a well charged bat-

tery. Each cell should be filled to level
with distilled water.

6- Check brake fluid level. If too low, have

brake system checked.
7 - Replenish windshield washer fluid.
8 - Replace worn or cracked wiper blades.
9 - See that all windows are clear and un-

obstructed.

10 - Check whether headlight and tail light

lenses are clean.

11 - Check under car for leaks.
12 - Be sure all lights are working and head-

lights are aimed correctly.

1 - Depress plate in center of steering wheel

to check whether horn is working.
2 - Position seat for easy reach of controls.
3 - Adjust inside and outside rear view mir-

rors.
4 - Use safety belts.
5 - Check operation of foot and parking

brakes.
6-Check all warning and indicator lights

when starting the engine.
7- Do not leave car idling unattended.

8 - Lock doors from inside, especially with

children in the car.

Have the engine oil, the coolant level and the

oil level of the automatic transmission
checked regularly, even in-between the re­commended maintenance intervals.

1 - Always drive defensively. Expect the

unexpected.

2- Use signals to indicate turns and lane

changes.
3 - Turn on headlights at dusk.
4 - Always keep a safe distance from the

car in front of you, depending on traffic,

road and weather conditions.
5 - Reduce speed during night hours and

inclement weather.
6 - Observe speed limits and obey highway

signs.
7 - When tired, get off the highway, stop and

take a rest. Turn the engine off. Do not
sit in the car with engine idling. See
warning on Engine Exhaust.

8 - When stopped or parked, always set the

parking brake.

9 - When stalled or stopped for repairs,

move the car well off the road. Set the
emergency flasher and use road flares
or other warning devices to warn other
motorists.

Turn the engine off before you attempt
any checks or repairs on the car.

Do not invite car theft!

An unlocked car with the key in the ignition

switch invites car theft.
A steering wheel lock and a buzzer alarm

are standard equipment in your Porsche.
The buzzer will sound if you open the driver's
door while the key is still in the ignition lock.
This is your reminder to remove the key from
the ignition and lock the doors.

Do not remove the key from the steering

lock while you are driving or as the car is

rolling to a stop. The steering column is lock­ed when you remove the key, and you will
not be able to steer the car.

The new format of the master and auxiliary
keys makes unauthorized duplication of the
keys virtually impossible. This means, how­ever, that you yourself will not be able to get
replacement keys cut, unless ordered from
the manufacturer.

Should you need new keys, you must give
the key number. This number is noted on the
plastic tag on the keys. Keep this tag in a
safe place - not in the vehicle.

a Master key
b Auxiliary key

Keys

Your Porsche comes with two each of the

following keys:
a- master key for ignition lock, door locks,

luggage compartment lock and glove
compartment lock.

b - auxiliary key for ignition lock, door locks

and luggage compartment lock

Key light

The master key has a built-in flashlight in the
key head. The beam from a small bulb in the
key head illuminates the lower part of the key
stem.
The flashlight is on as long as the contact
button is depressed.
The flashlight is powered by a 1.5 Volt button
battery. When the beam begins to fade, re­place the battery, because an old battery

may leak and damage your clothes.

Anti-theft alarm

(optional equipment)

If your Porsche is equipped with an anti-theft
alarm system, you will be given the two keys
illustrated and described above.

The alarm system is activated when the
driver or front-seat passenger door is locked
with the black key. Opening the driver or
front-seat passenger door by any other
means when the alarm system is activated,
will produce an intermittent high noise for
about 30 seconds.

black key only - activate alarm by locking and deactiv­ate alarm by unlocking

red key only - lock and unlock without activating alarm
black key and red key
black key and red key- alarm must be deactivated
red key only
black key only

The same alarm is also triggered when an
attempt is made to open the luggage com­partment lid or the engine hood. The engine

cannot be started while the alarm system

is activated.

The alarm system can only be deactivat­ed by unlocking the driver or front-seat
passenger door with the black key.

The red key can be used to lock and unlock
the doors when activation of the alarm is not
necessary, or when the car is being serviced.

The fuel cap can only be unlocked with the
red key.

The glove compartment lock can only be un­locked with the black key.

Either key can be used for the luggage com­partment lock when the alarm is deactivat-
ed. Either key can be used in the ignition/
steering lock.

Keep the plastic tags with the key numbers
in a safe place - not in the car!

10

Central door locking system

The central door locking system enables
you to lock or unlock both doors simultane­ously by operating one door lock.

The central door locking system functions
only when both doors are fully closed. If one
door is „centrally" locked before the other
door is fully closed, the „centrally" locked
door will unlock automatically.

The car is safely locked when locking knob
„A" is fully down on both doors. If locking

knob „A" is not fully down on one door, open
that door again, close it firmly and repeat the
locking operation.

On a centrally locked vehicle, the passenger

door can also be unlocked and locked from

inside by turning locking knob „B". Locking

knob ,,B" is operational only with door fully
closed.

With the ignition key in Pos. „1" or „2" the
electric circuit of the door locking mechanism

is interrupted, so that each door can be un-

locked or locked from the inside only by

manually raising or depressing locking knob

„A". This safety feature prevents the doors
from being locked automatically through a
short circuit or during an accident.

With the ignition key in Pos. „0" the central

locking system and locking knob „B" are
operational.

Doors

To open doors from outside, pull the re­cessed door handle.

To open doors from inside, pull recessed
handle „C" above armrest.

The armrests have a built-in storage comp­artment. To open, press knob in hand cutout
and tilt armrest outward. To close, tilt comp­artment toward door panel.

Door windows

To open or close, depress the rocker swit­ches in the center console in front of the
shift lever.

Caution: Remove the ignition key to shut
off power to the window switches when
the vehicle is not attended by a respon­sible person.

The courtesy light in the lower door panel
„D" will come on when a door or the hatch­back is opened. The light can also be turned
on or off with the switch on the light housing.

AIways drive with locked doors to prevent
inadvertent opening of a door from the in­side, especially with small children in the
car.

11

Front seats

Correct seat positioning is important for safe
and comfortable driving. Therefore, the seat
and the backrest angles in your Porsche are
fully adjustable.

Seat adjustment

To move the seat forward or backward, pull
the locking lever at the front of the seat up.
Now slide the seat to the desired position.
Let the lever go, and move the seat slightly
back and forth to make sure it is securely
engaged.

Do not attempt to adjust the driver's seat
while driving! The seat may suddenly jerk
forward or backward causing loss of con-

trol.

Backrest release

The backrest can be folded forward for easy
access to the rear seats. To release, press
the locking button on the side of the back­rest (arrow) and, at the same time, tilt the
backrest forward. When the backrest is tilted
back, the lock will engage automatically.

12

Backrest adjustment

Turn handwheel on the outboard side of the
seat (arrows), with your body weight taken
off the seatback.

Front passengers should not ride in a
moving car with the seatback reclined.
Safety belts offer maximum protection
only with the seatback in an upright posi­tion.

For maximum legroom and unobstructed

view of the instruments, the steering wheel
and the instrument cluster unit can be un­locked (arrow), adjusted, and then re-locked.

Rear seats - luggage compart-

ment

The backrests of the rear seats can be tilted
forward to provide additional luggage space.

Unsnap the luggage compartment cover
from the upright rear seat backrests and the
rear cross wall.

To release backrest, pull the lever on side of
the backrest up and, at the same time, tilt
the backrest forward.

-

Interior lights

The dome lights have a built in rocker switch
which is operated by tilting the lamp lens as
follows:
a - light on with front doors or hatchback

open
b - light off
c - light on continuously.

Switch positions for the lower door panel
lights are as follows:
up - light is continuously
center- light off
down - light on with doors or hatchback

open.

a backward/forward
b height
c backrest angle

Electric seats
(optional equipment)

The rocker switches for a smooth three-way

seat adjustment are located at the outboard
side of the seat.

To permit easy access to the rear, the seat
will slide forward automatically when the
backrest is folded down (with ignition on or
off). The seat will remain in a position that
permits comfortable entry to the front, when
the backrest is tilted back to its upright po­sition and securely locked.

Note:

Before operating the switches, tilt the safety
belt buckle at inboard side of seat out of the

way to prevent the buckle from getting

squeezed inbetween seat cushion and back­rest, which could damage both buckle and
seat cover.

Manual operation

If the electric mechanism fails, the seat can
be moved forward or backward by pushing
the locking lever under the front of the seat
toward outboard side of seat. Slide the seat
to the desired position and let the lever go.

Move the seat slightly back and forth to make
sure it is securely engaged.

13

Ignition/Starter Switch with

Steering Lock

The steering is equipped with an antitheft
ignition lock.

For your safety, fasten safety belts.

Manual transmission:
 Move gearshift lever to Neutral.

Automatic transmission:
 Move gearshift lever to Neutral or Park.

Never start or let the engine run in an en­closed unventilated area. Exhaust fumes
from the engine contain carbon mono-

xide which is a colorless and odorless
gas. Carbon monoxide can be fatal if
inhaled.

There are 4 positions:

0 Steering locked. All electric circuits

wired through the ignition switch are
turned off. The ignition key can only be
withdrawn in the "0" position. The park-

ing lights can be operated in this position

by pushing the turn signal indicator lever

up and down (also see "Parking lights").

1  Steering unlocked. In this position all

electric circuits are operational except
for the following: turn signals, stop

lights, backup lights, outside mirror

remote control, rear window defogger/
defroster and fresh air ventilation. The

instrument cluster illumination will come

on and can only be turned off with key in

position "0".

2 Ignition on, steering unlocked. All

electric circuits are operational. With the
engine stationary, the central warning

light and all individual warning lights loc-

ated in both combination instruments
will light up for a bulb check.

3  The starter is operated by turning the

ignition key to the right. As soon as the
engine starts, release the key. It will
spring back to position "2". With the
engine running, the central and indivi-

dual warning lights should go out. The
STOP LAMΡ will go out after depressing
the brake pedal and the PARK BRAKE
light after fully releasing the parking
brake (see "Central warning light sys­tem"). To conserve battery power, the
electric circuits for headlights, rear win­dow defogger/defroster and wiper/
washer system are temporarily inter­rupted during the starting process.

The starter should not be operated for more
than 10 to 15 seconds at a time. If the engine
does not start the first time or stalls at any
time, the ignition will have to be switched off
and then on again. The nonrepeat lock in
the switch prevents the starter from being
operated when the engine is running and
thus from being damaged.
To remove the key and to lock the steering
turn the key back to position "0" and pull it
out. Turn the steering wheel until it locks.

If you leave the key in the ignition/steering
lock, the buzzer will sound when the driver's
door is opened. This is your reminder to re­move the key.

See also Starting Hints and Brakein Pe­riod.

The steering column will lock when you
remove the key. Therefore do not remove
the key while you are driving or as the car
is rolling to a stop.

14

Inertia Real Safety Belt

For your and your passenger's protec­tion, wear safety belts at all times while
the car is in motion.

Your Porsche is equipped with a safety belt
for each front and rear seat.

The inertia real safety belt provides safety
with freedom of movement. It adjusts auto­matically to your size and movements as
long as the pull on the belt is slow. A sudden
motion locks the belt.

Rapid deceleration during hard braking or a
collision locks the belt. The belt will also lock
when you drive up or down a steep hill or in a

sharp curve.
To release a locked belt, lean back to take

the body pressure off the belt.

A shoulder belt should not be worn by a

person less than 4' 7"/1.40 m in height,
or with an erect seating height of less
than 2' 5" /74 cm, because the belt would

not be in its most protective position and

may therefore increase the possibility of

injury in a collision.

For maximum safety and protection, we

recommend that small children travel in
the rear seats.

When driving in foreign countries, the wear-

ing of safety belts may be required by law.

Safety belt warning system

An audio-visual warning system is intercon-

nected with the driver's safety belt.

When the ignition is turned on, the warning

light in the center console and the buzzer
will come on for about 6 seconds. The buzzer
will go off as soon as the driver has buckled
up. The warning light will go off after 6 sec­onds.

Fastening the belt

Sit back in your seat so that your body is
supported by the backrest. Grasp the belt
tongue and pull the belt in a slow continuous
motion across your chest and lap. Insert the
belt tongue into the belt buckle on the inboard
side of the seat. Push down until securely
locked with an audible click.

Be sure the belts are not twisted.

15

Adjusting the belt

For best protection, belts should fit snugly
across lap and chest. If belt has too much
slack, pull shoulder section in direction of
arrow to make sure the belt is drawn snug
around your hips.

Make sure the shoulder belt does not press
against solid or fragile items, such as ball
point pens, pipe, lighter or glasses.

Do not wear the belts loosely.
Do not strap in more than one person with

each belt.

Releasing the belt
To unfasten belt, push the red release but-

ton marked PRESS. Belt tongue will spring

out of buckle.
To store lap/shoulder belt, allow belt to wind
up on retractor as you guide belt tongue to
its stowed position on door post. Mark sec­tion across your lap with moveable stop to
keep belt tongue from sliding down when
belt is wound up.
The belt of the unoccupied passenger seat
should always be fully wound up, with belt
tongue in stowed position. This reduces the
possibility of the belt tongue becoming a
striking object in case of a sudden stop.

Belt care

Belts that have been subjected to excessive
stretch forces in an accident should be re­placed.

If belts show damage to webbing, bindings,
buckles or retractors, they should be re­placed.

If belts do not work properly, see your
Porsche dealer to have them repaired or re-

placed.
Do not modify or disassemble the safety

belts in your car.
Keep belts clean. If they need cleaning, use

a mild soap solution, but do not remove belts
from car. Do not use other cleaning agents
as they will weaken the webbing.

Never bleach or dye safety belts.
Do not allow safety belts to retract until they

are completely dry. Dry belts in shade.

The seatbelt should not be used to hold a
child's seat as the diagonal belt will not
provide the needed protection.

Windshield wiper/washer and
headlight washer (where
applicable) lever

This lever has 6 switch positions. The elec-

tric wiper system is actuated by pulling the

lever up or down to the following 4 positions:
0 - wipers turned off

1 - wipers on slow speed
2 - wipers on medium speed
3 - wipers on fast speed
4 - wipers on intermittent speed

The intermittent wiper interval can be ad­justed by turning thumbwheel "A" on the

right side underneath the instrument cluster.

20

The electric washer system is actuated as
follows:
5 -pull lever toward steering wheel to ope-

rate windshield washer. Fluid can be
sprayed onto the windshield from any se­lected wiper speed position

6-push lever toward instrument cluster to

operate headlight washer

The headlight washer system operates only
with the headlights on and raised.

Before operating the wipers, the wind­shield must be sufficiently wet to prevent
the glass surface from being scratched.
Check wiper blades frequently and re­place at least once a year.

Intensive windshield washer

system (where applicable)

By depressing switch "B" on the right side
underneath the instrument cluster, a supply
of special intensive cleaning solution is
pumped to the windshield. Heavy road dirt,

silicone or insects can be removed quickly
without smearing. The spray duration is con­trolled by a time relay to avoid excessive

use of the special cleaner. The regular wind­shield wiper/washer system can then be
operated to finish the cleaning process.

Automatic Speed Control

The automatic speed control allows you to
maintain a constant cruising speed of 30 mph
(50 km/h) or higher, without actuating the
accelerator pedal. Any manual operation,
such as accelerating, gearshifting or braking
can be done independent of the automatic
speed control. The spring loaded control
lever operating the automatic speed control
is located just below the wiper/washer lever.

CAUTION: While driving with the automa­tic speed control set, do not bring shift
lever into the Neutral position which will
result in very high engine rpm and conse­quent damage.

To operate the automatic speed control

- Accelerate to the desired cruising speed,
push lever toward instrument cluster
(arrow 1) and release. This sets the cruis­ing speed and stores it in a memory.

- After a second or two automatic speed
control will take over, and you can remove
your foot from the accelerator pedal. The
set cruising speed will be maintained au-

tomatically.

- Passing: when you want to drive faster

for a brief moment, for example when
passing another vehicle, actuate the ac­celerator. When you take your foot off the
accelerator pedal, the preset speed will
automatically be resumed.

- Gearshifting: when shifting gears, the

automatic speed control is only disengag­ed as long as the clutch pedal is depress­ed. The preset speed will be resumed as
soon as you take your foot off the clutch
pedal.

- Braking and stopping: whenever you

apply the brake or come to a stop, the

. automatic speed control is disengaged.

Move the lever down (arrow 2), and the
preset speed will be resumed.

- Switching system off: to switch the au-

tomatic speed control off, move the lever
toward you (arrow 3). To resume the pre­set speed, move the lever down (arrow 2).

To change the preset cruising speed
Increase preset speed:

- Accelerate by depressing the accelerator
pedal. When the desired speed is reached
move the lever up (arrow 1) and take the
foot off the accelerator pedal. Now the
new cruising speed is set and stored in the
memory.

- As an alternative, you can hold the lever
in the up position (arrow 1), without de­pressing the accelerator pedal. The car
will accelerate on its own. When the de­sired speed is reached, release the lever.

Decrease preset speed:

- Apply the brake, which will disengage the
automatic speed control. When the ve­hicle has slowed down to the desired
speed, move the lever up (arrow 1) to set

the new cruising speed.

- As an alternative, disengage the automa­tic speed control by moving the lever to­ward you (arrow 3). When the vehicle has
slowed down to the desired speed, move
the lever up (arrow 1) to register the new
cruising speed in the memory.

Note: When driving up a hill, if the engine
power is insufficient in a particular gear, the
speed control will be disengaged automatic­ally. Shift to a lower gear to avoid lugging

the engine.

CAUTION: Do not use the automatic
speed control when driving on winding
or slippery roads, or in varying and dense

traffic.

21

Tachometer

The transistorized tachometer operates on
the pulse count principle and shows engine
speed in revolutions per minute (rpm).

The red mark at the end of the scale indi­cates the maximum permissible engine rpm.
Before reaching this area, the next higher
gear should be selected. Earlier shifting
saves fuel.

Shift to the next lower gear when the engine
rpm drops below 1500 rpm.

The speed limiting governor prevents the
engine from being overrevved under load.

Speedometer

The speedometer indicates driving speed
per hour.

In USA: Miles and Kilometers per hour
In Canada: Kilometers per hour

The upper odometer records total distance
driven and cannot be turned back.

The trip odometer in the lower part of the
instrument can be turned back to zero by
depressing the odometer reset switch on the
lower left side of the instrument cluster.

High beam indicator light

The blue light in the instrument cluster will
light up when the selector lever is pushed
forward. The blue light will go out as soon
as low beam is selected.

Turn signal indicator light

The green signal indicator light in the instru­ment cluster will flash with the selector lever
in either up or down position. If a turn signal
bulb becomes defective, the indicator light
flashes at about twice the normal frequency.

Central warning light

The central warning light in the instrument
cluster will light up or flash when a fault
occurs in one of the vehicle's systems. (Re­fer to "Central warning system").

Combination Instruments

Coolant temperature gauge

Needle in white field  engine is cold

As long as needle is in white field, avoid

high speeds and high engine rpm, until
engine has reached normal operating
temperature. Do not lug the engine.

Needle in center striped field  normal

Under normal driving conditions, needle
should remain in center field. The needle
may reach the red field, especially at high
engine loads, but should return to "normal"
when engine load is reduced.

Needle in red field  warning

If needle enters the red field, the engine is
overheating. The central warning light will
also come on. Reduce speed and engine
rpm. If the needle does not return to the
center field, and the central warning light
remains on, pull off the road, turn off the
engine and let it cool down.

Coolant temperature
warning light

If this light comes on, the electric fan or the
belt driven mechanical fan may not be
working to provide sufficient cooling. Pull off
the road and turn off the engine. If the elec-
tric fan is working, it may still be running for
awhile.

WARNING: Wait until engine has cooled
down. The radiator fan switches on auto­matically when the coolant reaches 92° C
(198° F) and continues running  even
with engine turned off  until the coolant

temperature has dropped to 87° C(189° F).

If the electric fan does not work, check for
a blown fuse or contact nearest workshop.

If the mechanical fan is not working, the fan
belt may be loose or broken. The belt should
be retensioned or replaced.

Fuel gauge

With the ignition on, the amount of fuel in
the tank is indicated by the fuel gauge
needle.

Fuel level warning light

This light comes on when the fuel reserve
level in the tank is down to about 2.11 U.S.
gals, or 8 liters. Time to refuel.

The central warning light and the warning
lights in the combination instrument light up
for a bulb check when the ignition is turned
on. They should go out as soon as the engine
is started. Also see "Central warning light

system".

TAIL LAMP warning light comes on when a

bulb is defective.

STOP LAMP warning light comes on and
goes out after depressing the brake pedal.

If the light stays on a bulb is defective.

WASHER FLUID warning light comes on
when level in the windshield / headlight
washer reservoir is down to 2 U.S. qts. or 2
liters.

PARKING LIGHT indicator comes on when
the parking lights are turned on. The light
will go out as soon as the headlights are
switched on.

COOLANT warning light comes on when
coolant level in the expansion tank falls
below the required minimum (see "Cooling
system" and "Filling capacities").

Oil pressure gauge
Oil pressure warning light

Engine oil pressure is shown in bar. At 5000
rpm, with the engine at normal operating
temperature, the oil pressure should be
about 5 bar. A slight drop in oil pressure at
higher temperatures is normal.

If the oil pressure should drop suddenly
while you are driving, this light and the cen­tral warning light will flash. Pull off the road
and stop the engine immediately. Check
the engine oil level. If it appears to be normal,
contact the nearest workshop.

Voltmeter
Alternator warning light

The voltmeter shows the overall condition of

the charging system. The needle should nor-

mally stay in the 12-14 volt range when the
engine is running. A temporary drop below
12 volts when starting the engine is normal.

The alternator warning light comes on when
the ignition is turned on and goes out as the

engine rpm increases. If the light does not
light up when turning the ignition on, or if it
does not go out after starting the engine,

there may be a malfunction in the electrical

system. If this is the case, contact your

Porsche dealer. If the light flickers or stays on
while you are driving, the V-belt may be loose
or broken. The belt should be retensioned or

replaced. The fault may also be in the regu-

lator or the alternator itself. In this case, keep
electrical consumption at a minimum and
drive to the nearest workshop.

The central warning light and the warning

lights in the combination instrument light up
for a bulb check when the ignition is turned
on. They should go out as soon as the engine

is started. Also see "Central warning light

system".

OXS (oxygen sensor) light

The OXS light functions as a "Service

Reminder". The light will come on (and stay
on) every 30,000 miles or 48,000 km to re­mind you to take your car to your Porsche
dealer for the scheduled emission control
maintenance service.

The OXS lamp lights up when the ignition is
turned on and should go out after the engine
has been started. If the light does not go
out after the engine has started, a malfunc­tion may have occurred in the monitoring
system. Have your dealer locate and correct
the cause promptly (see "Emission Control
System" for more details).

BRAKE FLUID warning light flashes when
the brake fluid level falls below the required
minimum.
BRAKE PAD warning light comes on when
a brake pad is worn.

BRAKE PRESS warning light flashes if one
of the circuits in the brake system should fail.

PARK BRAKE warning light comes on and
stays on until parking brake is fully releas-

ed.
ENGINE OIL warning light flashes if, with

the ignition on, the engine stationary, and
the vehicle in level position, the amount of
oil in the sump is less than 1.59 U.S. gal. or
6 liters. Do not attempt to start the engine!

Add oil at once.

Central warning light system

This electronic warning system monitors the
most important functions of your Porsche
for increased safety and reliability of per­formance. Should a problem arise, the cen­tral warning system will inform you imme­diately.

The central warning light is located in the
center of the instrument cluster. The indi­vidual warning lights are divided between
the two combination instruments.

When the ignition is turned on, the central
warning light and all individual warning lights

will light up for a bulb check. As soon as the
engine is started, the lights should go out.
The STOP LAMP light will go out after the

brake pedal has been depressed. The PARK
BRAKE light will go out as soon as the park-

ing brake lever is fully released.

Should a problem arise, the central warning
light will light up or flash, together with the
respective individual warning light.

Note: If the engine has been started by tow­ing or pushing, the warning lights will not go
out. The ignition must be turned off and the
engine restarted.

The control function of the central warning
light system is divided into two major
groups:

Group "A"- engine oil pressure

- engine oil level

- brake circuit (pressure) failure

- brake fluid level

Any malfunction reported by the system

must be corrected immediately.

Group "B"- brake wear (pads) indicator

- parking brake

- coolant level

- coolant temperature

- fuel reserve level

- windshield and headlight
washer (where applicable)
fluid level

- stop lamps

- tail lamps

Any malfunction reported by the system
should be corrected as soon as possible.

Reset button (white arrow)
By pressing this button, you can turn off the

central warning light for group "B" related
problems. The individual warning light in the
respective combination instrument will re­main on as a reminder to have the fault cor­rected.

The reset button does not apply to group
"A" related problems. Both central and in-

dividual warning lights will continue to flash
because an immediate remedy of the pro­blem is necessary.
