Road Test
There are two purposes for conducting a road test.
Firstly, to ensure the work completed within the
dealership meets the standards required as laid
down by dealership processes. Secondly, for a
skilled technician to assess the general condition of
the vehicle and report any conditions that the
customer should be made aware of.
CAUTION: Two wheel dynamometer tests must
not be carried out. Four wheel dynamometer
tests must be restricted to 3 mph (5 kph).

positions.
Selector Cable – (Automatic only)
1.Check for correct setting of gear selector cable.
Engine Performance and Throttle Operation
1.Start engine and check that it starts easily.
2.Check that 'oil pressure' and 'no charge'
warning lamps extinguish.
3.Check that throttle pedal movement is free and
unrestricted.
4.Check that engine is responsive to throttle
movement.
Clutch and Gear Selection –
(Manual only, normal driving conditions)
1.Check that clutch engages smoothly without
judder, slipping or noise.
2.Check for abnormal transmission noise.

the opposite direction.
Steering
1.With vehicle stationary, turn steering from lock
to lock. Check for smooth operation and ensure
there is no undue noise from the power steering
pump or drive belt.
Suspension
1.Check for noise, irregularity in ride (e.g.
dampers) and wheel imbalance.
Foot brake
1.Check for pedal effort, travel, braking
efficiency, pulling and binding.
Handbrake
1.Apply handbrake firmly, check travel and
ratchet hold and release.
Instruments
1.Check for correct operation of all instruments
and warning devices where practical.
Body
1.Check for abnormal body noise.

vehicle systems for correct operation. Pay
particular attention to:
lEngine noise
lGearbox noise
lSuspension noise
lBody noise
lBraking system operation
lGear selection
lEngine performance
2.Where possible, check for correct operation of
Hill Descent Control (HDC) system. This should
not be carried out if excessive journey time is
required.
3.After road test, carry out a final inspection of the
vehicle on vehicle ramps.
4.Check all underbonnet fluid levels and top-up if
necessary.
