2.2 VEHICLE RECOVERY
8 2.2.1 General
m: Prior to vehicle recovery, always ensure the vehicle
keys are available and the vehicle security system is
'OFF'.
The safest and preferred method of vehicle recovery is by
flat bed transporter, although a rear suspended tow may
also be used.
The front and rear towing eyes are provided for use only in
an emergency to move the vehicle
if it is causing an
obstruction, on police instructions, or, when winching the
vehicle onto a recovery transporter.
m: A towing shackle cannot be fastened to the front
towing eye until the grille vane has been removed.
To do this, remove the (three) quarter
-turn fasteners
securing the grille vane (Fig. I), and place the vane
safely to one side. The towing shackle may now be
secured to the towing eye.
0 When thevehicle is being towed (see Towing Recovery), the
gear lever must be set to neutral, 'N' (see Gear-shift Inter- lock) and the ignition key turned to position 'II'to release the
steering lockand renderthe indicators, horn and brake lights
operational.
2.2.2 Gear-shift Interlock
The gear selector lever may only be moved from the park 'F" position by turning the ignition key to position '11' on the key
switch and applying pressure to the footbrake pedal.
To remove the ignition key from the key switch, the gear
selector lever must be moved to park
'P. With the key removed, the gear selector lever will be locked
in park
'P'.
2.2.3
In the event of electrical failure or when moving the vehicle
without power, the gear selector lever can be manually
unlocked from park
'P'. Below the left-hand side of the 'J' gate (Fig. Z), is the gear- shift interlock manual release catch. With a flat bladed
screwdriver, remove the plug, arrowed (Fig. 2). Insert
ignition key and press down catch whilst simultaneously
moving the gear
-shift lever from 'P' position.
Gear-shift Interlock - Manual Override
U: Gear-shift lever can only be moved approximately
25mm with the key still inserted.
Remove key and replace plug. Fig.

12.1 ANTI-LOCK BRAKING SYSTEM (ASS), GENERAL DESCRIPTION
The anti-lock braking system (ABS) components are combined with a hydraulic booster and tandem master cylinder (TMC) to provide a two-circuit braking system. The anti-lock braking system comprises the following components:
0 Four inductive wheel speed sensors, hub end mounted
0 ABS warning light
0 Hydraulic module.
The hydraulic module consists of an electric motor driven pump,
two low pressure accumulators, valve block and an
ABS electronic control module.
m: Electronic control modules for vehicles without traction control are designated ABS CM. Control modules for
vehicles with traction control are designated ABS /TC CM.
The valve block houses solenoid operated valves which are activated by voltage signals from the control module. The
signals are generated using wheel speed information received from the wheel speed sensors.
For vehicles without traction control the valves operate on three circuits, two front and one rear, as necessary to pre
- vent wheel locking during braking. Brake pressure is modulated individually at thefront wheels and collectively at the
rear. Rear wheel control operates on a 'select low' principle i.e. locking in either wheel is sensed, and controlled brake
pressure is applied to both wheels.
For vehicles with traction control the valves operate on four circuits. During ABS control the rear wheel are controlled
on a 'select low' principle (as above), but during traction control operation the rear wheels are controlled individually.

1yQfB: Functional and diagnostic information for the ABS CM and the ABS/TC CM is contained in the Electrical Diag-
nostic Manual (EDM), Section 12.
ABS Warning lamp / Traction Control Warning lamp /Fluid level Indicator
The ABS and traction control warning lamps, mounted in the instrument panel, indicate a fault in the ABS or traction
control. These systems are inhibited or disabled when the lamps are lit, although conventional braking is unaffected.
When the ignition is switched on, an ABS self test is initiated. During this test, the ABS and traction control warning
lamps are
lit for approximately 1.7 seconds and then extinguish. A fault is indicated if the warning lamps remain lit or
come on whilst the vehicle is being driven.
W: The ABS self test is masked by the 5 second lamp test initiated when the ignition is switched on.
The fluid level indicator lamp, mounted in the instrument panel, is
lit when the brake fluid falls below the minimum
mark on the brake fluid reservoir.
ABS / Traction Control - Inhibit / Disable
Faults conditions are detected by the ABS/TC CM which disables the ABS and traction control until the fault is rectified.
The ABS and traction control warning lights on the instrument pack remains lit whilst a fault exists. The system will
be disabled when the following conditions occur:
0
0 Valve failure
0 Sensor failure
0 Main driver failure (internal ABS /TC CM fault)
0 Redundancy error (internal ABS JTC CM fault)
0 Overvoltage J undervoltage
0 Pump motor failure.
0 Throttle valve actuator motor failure (traction control vehicles only).
0 Throttle valve actuator potentiometer failure (traction control warning light only).
X300 VSM 1 Issue 1 August 1994

The input frequency from each wheel speed sensor signal is translated by the ABS I TC CM, into a comparable wheel
speed. The ABS / TC CM continually monitors the system. False wheel speed information, such as sudden speed
changes in excess of 20 km / h or excessive speeds, are detected as a 'sensor malfunction'. The ABS / TC CM reacts
to fault conditions in the following ways:
Inhibit- ABS/traction control is inhibited until the sensed speed returns to within an acceptable limit, whereupon ABS
/traction control is restored. Conventional braking is unaffected. Depending on vehicle speed the ABS/traction control
warning lights may come on.
DisaMe - ABS /traction control is Disabled (switched off) and the ABS /traction control warning lights come on. The
system will not be restored until the engine is switched off and restarted orthe fault has been rectified. Afterthe system
has been disabled, the warning lamps remain on until the vehicle has reached a speed of 20 km/ h during thefirst igni- tion cycle after fault rectification.
Full diagnostic information for the ABS /TC
CM is given in the Electrical Diagnostic Manual (EDM), Section 12.

All vehicles are fitted with identical parking brake systems.
When the parking brake lever
is operated, the cable system applies equal force to both RH and LH brakeshoe expander
assemblies. The brake shoes expand and press against the hub assembly, locking the rear wheels.
The handbrake lever, ratchet assembly and warning
light switch (item 1) are mounted on the transmission tunnel by means of threeflanged screws a blanking plate and gasket. The front cable (item 2) is connected to the relay lever (item 3) which is mounted on the driveshaft securing bracket (item 4). The relay lever operates the intermediate cable (item 5) which incorporates an adjusting screw to allow cable tension to be adjusted. The intermediate cable operates the
equalizer which ensures that equal force is applied to RH and LH parking brakesvia rearcable RH (item 8) and rear cable
LH (item 9). The rear cables are adjustable to allow cable tension to be adjusted.
The park brake switch (item 10) latches when the lever
is operated and lights the parking brake warning light (item 11 mounted in the instrument panel.

13.4 TRUNK
13.4.1 Trunk, Description
The trunk houses the spare wheel, the battery, an electrical carrier containing electrical fuses, relays and modules and
a compact disc auto-changer attached to body bracketry. The trunk is fitted with push-fit, velour finish, liners (1 Fig. 1) to the sides and front inner panel; the trunk floor is covered with carpet attached to a removable floor board (2 Fig. 1) and a battery cover (3 Fig. I), one covering the spare wheel and wheel changing equipment, the other covering the
battery and electrical carrier.
The floor board rests on the spare wheel, the front and rear edges
of the floor board locating in blocks on the fuel tank
backboard and on the rear of the body. The blocks accommodate the two possible height settings caused by the differ- ence in thickness between the space saver and full sized spare wheels.
A tread plate (4 Fig. 1) is attached to the trunk sill and a liner is fitted to the rear of the trunk below the sill. Interior trim finisher panels are fitted to the rear lamp units accessed from the trunk opening.
The trunk lid
(5 Fig. 1) is fitted with a removable moulded liner and two trunk illumination lights; the lid is supported by two gas struts, attached through press-on fittings between the inner wheel arch and trunk hinge (6 Fig. 1). A warning
triangle is attached by a bracket to the trunk lid and retained in the open position by a rubber block (Europe inc UK only).
Trunk locking is based on a central latch and striker, operated electrically through the central locking system
by an ad- jacent actuator or by key in a barrel lock located behind the trunk lid badge.

Localized stains caused by accidental spillage may be one of three types:
0 Water based stainscaused byfoodstuffs,starches, sugars, soft drinks,fruit stains, washable inketc. These stains
adhere readily to the pile and do not respond to vacuum cleaning. They are best removed immediately using
the procedure detailed below.
0 Oil /grease based stains caused by spillage or other contamination by butter, grease, hand cream, ball point pen
ink, crayon, lipstick etc.
0 A combination of both these types.
Spot Cleaning - Localized Stains
To remove water based stains:
. Blot up liquids and /or scrape off semi-solids using a spatula.
. Sponge the affected area with clean luke-warm water. Use a clean, damp, undyed, cotton cloth to absorb as much

To remove oil /grease based stains:
. Using a suitable aerosol containing solvent loaded with absorbent powder, spray the affected areas of the carpet.
= Allow the solvent to evaporate and remove the powder containing the grease by using a vacuum cleaner or brush.
m:
CAUTION: Solvents must only be used in well-ventilated areas where naked lights and smoking are prohibited.
The solvent loosens the grease from the fibre and the powder then absorbs the grease-carrying solvent.
Neat solvent, eg dry cleaning
fluid, may be used, but should be used sparingly from a clean white cloth.
To remove stains which are a combination of oil and water based contamination (usually resulting from food or drink):
. Treat combination stains as for water based stains.
. Allow to dry out.
. Treat as for grease based stains.
