1. GENERAL INFORMATION

This Section of the Holden By Design Service Information Supplement, describes the m aintenance and service

procedures for the Hand Control System available with VT & WH Series vehicles.

Designed and only provided for driver s with special needs , the hand c ontrol s ystem allows brake and acc eler ator

control from a steering column mounted lever, which is operated with the right hand. A steering wheel ‘spinner’

knob and indicator stalk extension allow complete turning of the steering wheel and indicator operation with the

left hand.

The hand control system is available only with automatic transmission vehicles and meets AS 3954, motor

vehicle controls, adaptive systems for people with disabilities.

Most Austr alian States require the driver of a vehicle f itted with a hand control system hold a spec ially endorsed

licence.

NOTE: It is a mandatory requirem ent by licencing authorities f or the steer ing wheel knob to be f itted for dis abled

drivers.

The hand control assembly restricts access to the fuse panel. Section 3.1 provides a simple procedure for

accessing the fuses should servicing be required.

1.2 OPERATION

While operation of the hand control system is

relatively straightforward, familiarisation is required.

Brake application is achieved by pushing the lever

away from you, toward the dash (A). Pushing the

lever downward (B) toward your lap operates the

accelerator.

NOTE: It is recommended that non-authorised

persons do not drive a vehicle fitted with the hand

control system. However, circumstances may

necessitate service personnel drive such a vehicle.

Follow the procedures below and practice

maneuvering the vehicle in an isolated area before

driving the vehicle.

1. Start the engine.

2. W ith the engine at idle, depress the lever to apply

the brakes. Rev the engine slightly several times

to get the feel of the accelerator by pushing the

lever downwards.

3. Release the parking brake and place the

transmission selector in drive (or reverse if

required).

4. Release the brake lever while applying the

accelerator slightly.

5. Reapply the brake to get the feel of the braking

effort required.

6. Repeat as required until you feel confident of the

controls.
