w: The 'Premium Unleaded Fuel Only' caution is added to the Federal Market vehicles, also 'PARK BRAKE and
'BRAKE' replace international symbols used in all other markets.
m: Six cylinder vehicle version shown; the tachometer red-line on 12 cylinder vehicles starts at 6000 RPM.
The front of the
PECUSprogrammable instrument panel features 6 analog gauges, 22 warning lamps /tell tales and
a Liquid Crystal Display (LCD), the rear of the panel accommodates two PCB mounted connectors, one 24-way
connector, one 48-way connector, one instrument panel identification label and 14 light bulbs arranged in groups of
seven on either side. Three power inputs and two ground inputs are provided for 'POWER UP' and 'POWER DOWN'
sequence, the three power inputs comprising battery, ignition and auxiliary. The instruments are protected by a
housing
/ lens assembly.
15.2.7 Gauges
The two major gauges are tachometer and speedometer, and the four minor gauges indicate battery condition, fuel
level, oil pressure and coolant temperature.
Each gauge is contained
in a sealed non-serviceable can and must be renewed as a complete unit in case of any
damage.
CAUTION: Extreme care should be exercised when renewing instrument pand components to avoid damago to the delicate indicator needles.

15.2.8 Odometer
With the ignition 'OFF' the odometer is permanently dis-
played but not illuminated. With the ignition 'ON' the odo- meter is displayed and also illuminated.
Trip information or driver information messages may be dis
-
played instead of the 'ODO'. By pressing the 'ODO' button
once or twice the trip and driver information messages can
be deleted and the
'ODO rdisplayed.
W. The odometer value is not stored within the LCD
module.
15.2.9 Trip Computev
This provides information on the vehicle's speed, fuel usage
and distance traveled
all of which are calculated by a micro
processor.
The controls, part of the fascia switch assembly, are located
on the right
-hand side pod positioned to the right-hand side
of the steering column.

15.2.10 Driver Information Messages
Two fault messages, FLUID - AIRBAG are displayed via the LCD in conjunction with relevant warning lamps.
If an
airbag fault exists or the brake fluid is low, a message will automatically be displayed on the LCD and the relevant
warning lights illuminated. Should both faults exist at the same time, each message is displayed alternatively for ap
- proximately 2 seconds.
Messages may becancelled
by pressing the 'ODO button which allowsthe LCD to return to its last displayed message.
The warning lamps will not be extinguished. If the fault is not repaired the message(s) and the warning lamp(s) will
be redisplayed when the ignition is switched on.
15.2.11 /llumination
Warning indicator lamp illumination is controlled by a microprocessor located inside the instrument panel.
The seven right
-hand warning indicators are primary warning lamps illuminating 'RED and the seven left-hand warn-
ing indicators are secondary warning lamps illuminating 'AMBER'
The eight lower lamps are
a mixture of status and warning lamps.
With the ignition
'OFF' the LCD is not illuminated.
With ignition
'ON' and side lights 'OFF' the LCD is illuminated at maximum brightness.
With the ignition on and side lights
'OFF' the LCD is dimmed as are the gauges.
The long
life type bulbs are enclosed by orange and brown coloured bulb holders which must never be interchanged.
Replacement bulbs must always be of the same colour.
CAUTIQN: Always dwonnect the battery ground lead before commencing with any instrument rsimwal procedure.
15.2.12 General Repair Notes
0 After lens removal do not rest instrument panel face down as this causes damage to the delicate gauge needles.
Avoid scratching the gauge faces and ensure cleanliness when handling the panel.
0 To minimize the risk of damage and contamination to the instrument panel, all repairs must be carried out in a non - static and dust -free environment. Avoid touching connector pins and pcb components to minimize
risk of static damage.
0 The instrument panel has two different types of bulb holders each of which must be located correctly when
changing the bulbs.

15.5.8 wific Gravity Test
The specific gravity of the electrolyte determines the level of the float in the liquid. With the float in a high position
the specific gravity is high and when the specific gravity is low the float sinks to the lower position.
Using
a hydrometer the specific gravity readings are taken when the liquid level crosses the scale on float. This should
give a accurate indication of the state charge of the battery.
The volume and the specific gravity of the electrolyte varies with the change in temperature.
15.5.9 Electrolyte Temperature Correctkm
For every 10- below 15% subtract 0.007 from the hydrometer reading, and for every 10°C above 15OC add 0.007 to
the hydrometer reading.
Note: Use only distilled water for topping up electrolyte. The electrolyte must not exceed 51.66OC during charging.
If after 30 minutes charging the battery current is not equal or greater than 3A, dispose of the battery.
15.5.10 Heahh and Sakty Precautions
As batteries contain sulphuric acid and explosive mixtures of hydrogen and oxygen gases, it is strongly recommended
that protective clothing is worn.
Avoid spilling acid to prevent damage to clothing and skin bums.
If accidentalty spilled or splashed on clothing or skin, rinse with cold water. As a neutralizer, a solution of baking soda
or ammonia and water may be used.
In the event of skin or eye contact rinse the affected areas with water and should this not
be sufficient seek medical
attention.
Any trace of acid spilled or splashed on the vehicle should be rinsed with clean water.
BEFORE AND WHILST WORKING WITH THE BATTERY BE AWARE OF THE FOLLOWING SAFETY PRECAUTIONS
o particularly during charging, highly explosive hydrogen is emitted.
0 do not smoke when working near the battery.
o avoid sparks, short circuits or other sources of ignition.
o switch off current before connecting or disconnecting any electrical terminals.
o always disconnect battery ground lead first and reconnect last.
o ensure battery is charged in a well ventilated area.
o switch off the charger before disconnecting.
WARNING: WHEN PREPARING ELECTROLYTE OF A DESIRED SPECIFIC GRAVITY, ALWAYS POUR THE
CONCENTRATED ACID SLOWLY INTO THE WATER AND NOT WATER INTO THE ACID.
HEAT IS GENERATED WHEN MIXING ACID WITH WATER, HENCE ADD SMALL AMOUNTS OF ACID AND
STIR SLOWLY INTO THE WATER. ALLOW TO COOL IF NOTICEABLE HEAT DEVELOPS. EXCEPT FOR LEAD
DO NOT STORE ACID
IN EXCESSIVELY WARM LOCATIONS OR DIRECT SUN LIGHT.FUEL VAPOUR IS EXTREMELY FLAMMABLE, HENCE GREAT CARE MUST BE TAKEN WHILST WORKING ON THE FUEL
SYSTEM. LINED
CONTAINERS, ALWAYS USE NON
- METALLIC CONTAINERS AND / OR FUNNELS.
