REPAIR GENERAL INFORMATION
WARNING: This is a multi- purpose vehicle
with wheels and tyres designed for both
on and off road usage. Only use wheels
and tyres specified for use on the vehicle.
The vehicle is equipped with tubeless 'S','T' or 'H'
rated radial ply tyres as standard equipment. The
tyres are of European metric size and must not be
confused with the "P" size metric tyres available in
North America.
Vehicle wheel sets, including spare wheel, must be
fitted with the same make and type of tyre to the
correct specification and tread pattern. Under no
circumstances must cross-ply or bias-belted tyres be
used.
For tyre specification and pressures.

SPECIFICATION DATA, Information, Wheels and
Tyres
Alloy Wheels
Tubeless tyres are mounted on 7.0 inch wide by 16
inch diameter cast aluminium alloy wheels.The
surface has a paint finish covered with a clear
polyurethane lacquer. Care must be taken when
handling the wheel to avoid scratching or chipping the
finish.
The alloy wheel rim is of the asymmetric hump
type incorporating a safety hump to improve
location of the tyre bead in its seat. If difficulty is
experienced in fitting tyres to this type of rim.
See
Tyre Fitting
WARNING: Do not fit an inner tube to an
alloy wheel.
Steel wheels
Tubeless tyres are mounted on 7.0 inch wide by 16
inch diameter steel wheels.TYRE INSPECTION
Inspect tyres at weekly intervals to obtain maximum
tyre life and performance and to ensure compliance
with legal requirements. Check for signs of incorrect
inflation and uneven wear, which may indicate a need
for balancing or front wheel alignment.
See Fault
diagnosis, Tyre Wear Chart
if the tyres have
abnormal or uneven wear patterns.
Check tyres at least weekly for cuts, abrasions, bulges
and for objects embedded in the tread. More frequent
inspections are recommended when the vehicle is
regularly used in off road conditions.
To assist tyre inspection, tread wear indicators are
moulded into the bottom of the tread grooves, as
shown in the illustration below.
When the tread has worn to a remaining depth of 1.6
mm the indicators appear at the surface as bars which
connect the tread pattern across the width of the tread
as shown in the illustration below.

CAUTION: Ensure indicator cancellation
pegs correctly engage into back of

original rotary coupler is being fitted remove
adhesive tape and then fit rotary coupler to
column switch assembly.
NOTE: If original rotary coupler is to be
fitted and there is evidence of tampering, it
is imperative that the coupler is
centralised.
See rotary coupler centralise.
14.If a new rotary coupler is being fitted and the
sealing tape at positionBis broken it MUST
NOT be used.
15.Refit steering wheel.
See steering wheel.
16.Turn steering wheel to both LH and RH lock 5
times. If adverse noises can be heard, check
alignment of indicator cancellation pegs.
