Before inspecting a component for wear or per
forming a dimensional check,
ensure that it is absolutely clean; a slight smear
of grease can conceal an incipient failure. When a component is to be checked dimensionally against figures quoted for it,
use the correct equipment (surface plates, micrometers, dial gauges etc.) in serviceable condition. The use of makeshift
equipment can be dangerous. Reject a component if its dimensio ns are outside the limits quoted, or if damage is apparent.
A part may be refitted if its critical di mension is exactly to the limit size and it is otherwise satisfactory. Use Plastigauge 12
Type PG-1 for checking bearing surface clearance, e.g. big end bearing shell to crank jour nal. Instructions for the use of
Plastigauge and a scale giving bearing clearances in steps of 0.0025 mm (0.0001 in) are supplied with the package.

DISCONNECT TH

ENS
URE THAT FUME EXTRACTION EQUIPMENT IS USED WHERE APPROPRIATE.
FUME EXTRACTION EQUIPMENT MUST BE IN OPERATION WHEN SOLVENTS ARE USED E.G. TRICHLOROETHANE,
WHITE SPIRIT, SBP3, METHYLENE CHLORIDE, PERCHLORETHY LENE. DO NOT SMOKE IN THE VICINITY OF VOLATILE
DEGREASING AGENTS.
General workshop practices:
Disc
onnect the grounded termin
al of the vehicle battery.
D
o not apply heat in an attempt to free seized nuts or fitt
ings; as well as causing damage to protective coatings,
there is a risk of damage from stray heat to electronic equipment and brake lines.
Keep oils and solven
ts away from naked flames and other sour
ces of ignition.
Adhere str
ictly to handling and safety inst
ructions given on containers and labels.
E
nsure that a suitab
le form of fire extinguisher is conveniently located.
Wh
en using electrical tools and equipment, inspect the power
lead for damage and check that it is properly earthed.
D
o not leave tools, equipment, spilt oil etc. around the work area.
Working beneath a vehicle:
Wh
enever possible, use a ramp or
pit in preference to jacking.
Posit
ion chocks at the wheels as we
ll as applying the parking brake.
N
ever rely on a jack alone to support a
vehicle; use axle stands, or blocks care fully placed at the jacking points, to
provide a rigid location.
Ch
eck that any lifting equipment used has adeq
uate capacity and is fully serviceable.
Working on air conditioning systems:
D
o not disconnect any pipes of the refrigeration system
unless you are trained and instructed to do so; a refrigerant
is used which can cause blindness if allowed to come into contact with the eyes.

Jacking and Lifting - Jacking
Description an
d Operation
The vehicle jack and wheel chock are stored in the trunk as part of the vehicle toolkit.
Use of the vehicle jack and workshop jacks is desc ribed in the general procedures in this section.
Jacking Points

The four vehicle jacking points:
Are situ
ated below the body side members.
Are l

ocated behind each front wheel
and in front of each rear wheel.
Consist
of a square-section socket, pr
otected by a rubber cover, to provide positive engagement with the vehicle
jack.
Provi
de the support points for the four
lifting pads of a wheel-free lift.

Jacking and Lifting - Safety Precautions
Description and Operation

The following safety precautions must be observed wh en raising the vehicle to perform service operations:
Ne
ver rely on a jack alone to suppo
rt a vehicle; use suitable vehicle stands to provide rigid support.
When working ben
eath a vehicle, whenev
er possible use a ramp or inspection pit instead of a jack and vehicle
stands.
En
sure that the vehicle is
standing on firm, level grou nd before using a jack.
Do not rely
on the parking brake alon
e; chock the wheels and put the transmission into Park if possible.
Check that
any lifting equipment used has adequate capacity
for the load being lifted and is in proper working order.

Jacking and Lifting - Vehicle Recovery
Description an
d Operation
• NOTE: Prior to recovery, ensure that the vehicle keys are available and the security system disarmed.
Vehicle recovery methods are:
By fl
at-bed transporter.
By rear suspended tow.


By emergency to

wing for
very short distances.
Gears
hift Interlock
The
gear selector lever can only be moved
from the Park position by turning the igni tion key to position II and depressing
the brake pedal.
To remove the key from the ignition switch, the gear select or lever must be moved to the Park position. With the key
removed, the gear selector is locked in the Park position.
The selector lever can be manually unlocked from the Park position in the event of electrical failure or when moving the
vehicle without power. Refer to the general procedure in this section.
Transporter or Trailer Recovery

When the vehicle is being recove red by transporter or trailer:
The parking brake must be
be applied and the wheels chocked.
The

gear selector lever must be in Ne
utral. Do not select Park as the park ing lock mechanism may be damaged by
the forward and backward rocking motion of the vehicle.
The ve
hicle must be securely tied down to the transporter or
trailer. There are four tie-down brackets on the vehicle
underbody. Do not use the vehicle towing points or crossbeam tie bar.

Wh en t
he vehicle is being reco
vered by rear suspended tow:
The ignition key must be remo ved from the ig
nition switch to lock the stee
ring with the front wheels facing straight
ahead.
The re ar
wheels must be
correctly positioned in the lifting cradle and securely tied down.
Em
ergency Towing
WARNING: IF THE

ENGINE IS NOT
RUNNING, THE STEERING WILL BECOME HEAVY AND THE FORCE NECESSARY TO
EFFECTIVELY APPLY THE BRAKES WILL BE GREATLY INCREASED.
• CAUTIONS:
A vehicle with a defective transmission must be towed by rear suspended tow.
The vehicle towing point is not suit able for use with a solid tow-bar.
Do not use the crossbeam tie bar as a towing location.
When the vehicle is being towed on its own wheels:
Loc a
l regulations for the towing of ve
hicles must be followed. In some co untries the registration number of the
towing vehicle and an 'On Tow' sign or warning triangle must be displayed at the rear of the towed vehicle.
The gear s
elector lever
must be in Neutral.
The
ignition switch must be in positi
on II to release the steering lock and make the direction indicators, horn and
stop lamps operate.
A di
stance of 0.8 km (0.5 mi
le) must not be exceeded.
A spe
ed of 48 km/h (30 mph) must not be exceeded.
The tow rope must be attached using th
e towi
ng location provided; refer to Front Towing Point in this section.
