MAINTENANCE WIPERS AND WASHERS
1.Operate screen washer and switch on wipers.
Check washer jets are correctly aimed and
check for smooth smearless operation across
screen of wiper blades at all speeds, including
intermittent.
2.Repeat operation for rear screen
wipers/washers.
3.Check all wiper blades for condition and signs of
splits or damage.
4.Check security of wiper arms.HANDBRAKE
1.With the vehicle stationary, apply handbrake and
check for correct operation.See BRAKES,
Adjustment.
2.Release handbrake and check for correct
operation.
NOTE: Any adjustment required as a result
of the checking process will be subject to
additional labour and/or material cost and
should not be carried out without the
authorisation of the customer.
Adjust handbrake (First 12,000 miles/12 months
only
1.Adjust handbrake cable.See BRAKES,
Adjustment.
NOTE: Additional time is built into the first
12,000/12 months service time to allow for
handbrake cable adjustment.

CHASSIS AND BODY

DESCRIPTION AND OPERATION The tail door for 02MY is completely redesigned to address manufacturing complexity, corrosion and water ingress
probelms on previous tail doors.
The tail door is now a one piece outer skin pressing located on a reinforced steel, zinc plated frame. This gives
improved build quality, water integrity and minimal welding.
A new tail door glass is introduced with a one piece continuous rubber seal. The tail door glass has a revised
Heated Rear Window (HRW) element on the glass which removes the need to route wires up the sides of the
frame. The HRW element now has integral Lucar connections in the element which provide the earth connections
for the new centre high mounted stop lamp.
The inner trim panel is new and accommodates the CDL actuator and linkages.
The new tail door also contains a relay for rear wiper motor operation. Refer to the Wipers section for details.
Because the new tail door uses the current hinges and latch and retains the same geometry as the previous tail
door, the new tail door assembly is available as a service item for current vehicles.

WIPERS AND WASHERS

DESCRIPTION AND OPERATION Although windscreen wiper functionality remains the same, the mechanical architecture has undergone significant
changes. The body structure has undergone some minor changes to house the revised wiper linkage.
A modified wiper motor is introduced which is balanced to reduce operation noise. The brush plate is fitted with
capacitors to reduce radio interference and a thermal cut-out is introduced to prevent motor burnout. The motor
also contains a new park switch which also reduces operation noise. A common motor is now used on both LHD
and RHD variants.
The motor is repositioned on the bulkhead which allows a straighter drive cable run. The straighter run reduces
load on the cable allowing a stiffer cable to be used. The stiffer cable and the incorporation of a reduced friction
material reduces torsion wind-up of the cable and results in smoother wiper operation and a reduction of blade
over travel.
New, larger wheel boxes are fitted in an inverted position from the previous installation. The bulkhead mounting
holes are larger with flats for positive location of the wheel box spindle. The wheel boxes now feature a 40 tooth
gear ratio in lieu of a 32 tooth gear. This reduces backlash and load and further reduces blade over travel. The
wheel box casings are secured with locknuts.
The wheel box spindles now have a splined DIN taper fitting for the new wiper arms which are secured on the
spindle with an M8 nut. The taper improves arm retention.
A new grease is introduced which improves wiper operation at very low temperatures.
