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.

2.2.4 Transporting
If thevehicle is being transported on a trailer or flatbed transporter (Fig. I), the handbrake must be applied, the wheels
chocked and if fitted with an automatic transmission, the gear selector lever moved to neutral, 'N' (see Gear-shift
Interlock).

CAUTION: Do not select 'P' because the parking lock mechanism may be damaged by the continuous slight forward
and backward movement of the vehicle on the transporter.
There are four tie-down brackets on the vehicle underbody. Do not attach the tie down hooks of the transporter to the
towing eyes of the vehicle.
2.2.5 Towing Recovery
Adhereto local regulationsforthetowing ofvehicles. In certain countriesthe registration number ofthetowing vehicle
and an 'ON TOW sign or warning triangle must be displayed in a prominent position at the rear of the vehicle which
is being towed.
WARNING: WHEN THE ENGINE
IS NOT RUNNING, THE STEERING AND BRAKES WILL NO LONGER BE

SRO 12.41.02/20
The engine/transmission unit on the AJ 16 normally aspirated and supercharged engined vehicles are fitted ontothree
engine mounting/bracket assemblies. The two front engine mountings for the 3.2/4.0 liter normally aspirated and the
4.0 liter supercharged engined vehicles are identical. They are fitted to the front crossmember on either side of the
engine bay. Rubber to metal
engine/transmission rear mounts used for both engine types, are secured to a support
bracket which traverses the two body underframe longitudinal members. For access to remove the engine carry out the following procedures:

striker and the-fuel cap stowage magnet.
The fuel bowl, retained around the filler neck by a clip, containing a drain tube filter located over the mating drain tube,
is rubber moulded onto a steel armature and fitted to the BIW decking panel by five M5 nuts.
The fuel lid latching assembly fitted to the metal armature of the fuel bowl by an M5 nut, includes the locking pin and
the operating actuator.
The actuator operates from the central locking system driven by the security and locking control module
(SLCM).
The fuel tank, mounted across thevehicle behind the passenger compartment rear bulkhead, is held in position by two
retaining straps, tightened by two M5 fixing arrangements.
The fuel tank of AJ16 engined vehicles contains one fuel pump, supplying fuel to the normally aspirated engine and
two fuel pumps, supplyingfuel to the supercharged engine. They are regenerative turbine pumps supplied by
Nippon- Denso. Nominal operating pressure is 3 bar (3.7 bar for supercharged engine) above the manifold depression and
pump delivery is 90 litredhour minimum at 13.2 volts, 3 bar outlet pressure. The pump(s) draw a nominal current of 7 amperes at 13 volts, 3 bar outlet pressure, ambient temperatures. Built in to the pump assembly is a over-pressure
relief valve which blows at 4.5 - 8.5 bar.
Fuel is drawn by the pumps from the fuel tank and is then supplied to the fuel rail via a
70 micron filter and the fuel
feed line connected in series by fuel filter.
The amount of fuel being injected into the engine
is controlled by the fuel injectors combined with the engine control module (ECM). - Any excessive fuel flowing through the system, is returned to the fuel tankvia the fuel regulator valve mounted on the
fuel rail, the fuel return line and the check valve also located inside the tank.
The two filters prevent contaminants from entering the fuel rail and possible damage to the fuel injectors, the engine,
the pump and the underfloor filter.
The fuel pumps are switched on and off by relays controlled by the engine control module
(ECM).
The second fuel pump for the supercharged engine operates only in the higher speed range, switching on at 4000rpm and off at 3200rpm.
The fuel lines are made up of an assembly, combining steel under floor pipes and flexible conductive anti-permeation
tubing. In orderto perform speedy remove and refit operations, the underfloor steel lines are linked through the engine
bay bulkhead to the flexible tubing, leading to the fuel rail and the fuel regulator by using positive sealing, quick-fit
type connectors. The same type connectors, are used to connect the fuel feed and return line to the fuel tank.
Connectors used inside the engine bay are of different sizes tocorrespond with the difference in pipe diameter, whereas
the connectors for the feed and return lines at the fuel tank are the same size.
Except for the return line connector at the fuel tank, two release tools, one for each size of connector are required to
release all remaining connectors.
