Sidelam
ps and Headlamps
Thes
e are controlled by rotating the end of the column switch as follows.
In the OFF position:
All
exterior lamps are switched OFF.
In the sidelamp position:
The front
sidelamps, tail, license plate and any other la
mps required by local legislation are switched ON.
The
sidelamps tell-tale lamp illuminates.
In the headlamp position, with the ignition switch in position II:
The h
eadlamps are switched ON in addition to the lamps switched on in the sidelamp position.
If the ignition is switched to the OFF position with the column switch in the headlamp position, the sidelamps, tail and
license plate lamps will stay ON, but the headlamps will switch OFF.
In the AUTO position (where fitted), with the ignition switch in position II:
Th
e sensor mounted on the back of the interior rear view
mirror monitors exterior light levels and automatically
switches the sidelamps and di pped headlamps ON and OFF.
The sensitivity level can be adjusted by turn ing the sensor control knob on the back of the interior mirror, left to decrease or
right to increase. The sensor must not be covered and the windscreen must be kept clean.

th the column switch in
the headlamp position:
Movin

m the steering wheel switches the headlamps to main beam.
Movin

The main beam tell-tale lamp illuminates when the headlamps are switched to main beam.

th the ignition switch and column switch in any position:
Pulling the

switch stalk agains

M
essage Center Functions
T
he message center functions:
Are se

lected by the button located at the end of the lighting switch stalk.
Are se

lected in turn, by repeatedly pressing the button,
from the odometer reading, through the trip computer data
in sequence, and back to th e odometer reading again.

5.
Repeat steps 2 to 4 three
more times until all sixteen
valves on the first cylinder head have been adjusted.
6. Repeat steps 1 to 5 for the other cylinder head.
7. Remove all equipment and reassemble the engine.
8. The following instructions describe the PROCEDURE FOR
ADJUSTING THE VALVE CLEARANCES.

9. F
it the base plate of the tappet
adjusting tool 303 - 540 to one
of the heads; use the bolts which are supplied with the tool.
It
should be fitted along the head, between the two
camshafts, and bolted to the tapped holes which normally
secure the cam cover.
10. Rotate the crankshaft so that there are four valves which are
'off the cam'(cam lobes uppermos t), so that their clearance
may be measured.

11
.
CAUTION: Do not rotate the crankshaft while the
attachment is fitted to the base plate.
Fit the attachment of 303 - 540 to the base plate. 1. Set the fingers of the attachment to the highest position (unscrew the knurled bolts).
2. Fit the attachment to the base plate, adjacent to the first two valves to be adjusted.
3. Tighten the screws to secure the attachment to the base plate.

12
.
Position the fingers on to the outer edges of the tappet. It is
essential that the recessed step on each finger, locates on the
edge of the tappet as indicated. The use of a mirror will help,
as viewing access is restricted.

13
.
Tighten the knurled bolts to compress the valve springs, until
a firm resistan ce is felt.

1. Using a screwdriver, release clip at rear end of strut,
withdraw end from trunk lid pivot and lower strut.

Disconnect the tank ground cable from the vehicle body.
20. Remove the tank from the vehicle.
21. Drain any remaining fuel from the tank.
1. Fit the fuel tank assembly.

2. Re

troduction
It is very i
m
portant to positive
ly identify the area of concern before starting a rectification procedure. A little time spent with
your customer to identify the conditions under which a pr oblem occurs will be beneficial. See below for example:
Sym
ptom Chart
Re
lev
ant criteria are: Weather conditions,
ambient temperature, intermittent or cont inuous fault, airflow fault, temperature
control fault, distribution fault and air inlet problem.
Functio n
al Check
This
s
imple 'first line check' will allo
w you to ascertain whether the system is operating within its design parameters, withou t
recourse to PDU.
1. 1. With the engine at normal running temperature.
2. 2. Presss AUTO to display selected temperature and illuminate AUTO and A/C state lamps.
3. 3. Rotate FAN to increase or decrease lowe r speed, verify bar graph representation.
4. 4. Select A/C to toggle on or off. (T he compressor may be inhibited by the ECM should either the engine
temperature NOT be normal or the ambient be < 2° C).
5. 5. Select RECIRC , state lamp should be lit and the recirculation flaps open.
6. 6. Select distribution butt ons in turn, verify correct air distribution and relevant state lamp.
7. 7. Select DEFROST , check max fans and air to the windshield.
8. 8. Cycle TEMPERATURE to ' HI ' and ' LO ' to verify demanded variations and display operation. Note that extremes
will provide max heat or cold independent of in-car temperature.
9. 9. Select EXT to toggle between am bient and control temperatures.
10. 10. Select F (where fitted) and R - noting exterior mirror; verify timer and operation (glass may be warm to the
touch)
11. 11. Initiate system 'Self Test' to display stored faul ts should any of the above not perform as stated.

External temperature < -10 °C Vehicle speed > 65 km / h The first two conditions exist > 2 minutes. Engine speed > 50 revs / min
14. 14. Heated Backlight (R)
Pressing the heated backlight button will simultaneously energize the heater elements for timed cycles of;
21 minutes backlight 11 minutes exterior mirrors
Pressing the button again within the 21 minute timer will cancel the request.
If the engine is stalled, or the ignition switched OFF, the backlight and door mirror timers will be cleared, resulting in both
functions being switched off.
• NOTE: Both the backlight and door mirrors may be activated with the climate control system OFF, but the engine must be
running.
15. 15. Temperature Decrease
Pressing this button (BLUE symbol) decreases the interior temperature setting in 1° increments. Should the button be
pressed when the setting temperature is below the lower automatic control temperature limit, the display will indicate 'LO'.
16. 16. Temperature Increase
Pressing this button (RED symbol) will raise the temperature setting in 1° increments Should the button be pressed when
the setting temperature is above the upper automatic control temperature limit, the display will indicate 'HI'.

Parts List
Air temperature from the centre (and EOD) vents is slightly cooler than the foot outlets; however this temperature cannot
be varied independently.
The EOD vents, not shown, feature similar controls.
Automatic Operation
Initial setting
Should a new A/CCM be fitted, it will 'power-up' in the OFF mode; switching ON will result in the following settings:
After initial start up the system operating conditions will be st ored in the A/CCM to the conditions which prevailed prior to
ignition OFF.
