On The Road
Optimum braking efficiency is only achieved after bedding in brake disc/pads. It is important to avoid repeated hard use of the brakes during the PDI road test.
The road test is the only opportunity to assess the quality of ride, handling, general performance and noise levels under differing traffic and road conditions. Every care must be taken to make sure the vehicle performs to the standard of excellence expected by Jaguar customers.
Check the following:
- Parking brake operation. Refer to 'STANDARD CHECKS: FUNCTIONAL - PARKING BRAKE OPERATION '.
- That the steering will self-center from the right-hand and left-hand locks.
- The vehicle shows no tendency to wander or pull to one side.
- The steering wheel is properly aligned when the wheels are steered straight ahead.
- The direction indicators cancel when the steering wheel is turned onto the appropriate lock.
- The brakes do not pull to one side but operate smoothly without judder or noise.
- The transmission operates correctly.
All gear changes in automatic and manual modes are smooth:
When in automatic mode check that the message center displays 'P R N D S ', and that the current Jaguar Drive selection position is highlighted.
Check that the manual gear change operates correctly both in the 'D ' and 'S ' positions when the steering column shift paddles are used.
Also check that when the shift paddle is operated, the message center displays the manual gear ranges as '1 2 3 4 5 6 ' and the current Jaguar Drive selection is highlighted.
- Throttle pedal action.
- The 'kick down' feature operates correctly when changing down gear.
- All wash/wiper functions, horn, exterior lighting and headlamp levelling.

Refer to 'ROAD TEST - SPEED CONTROL SYSTEM ' or 'ROAD TEST - Adaptive Speed Control (ASC) System ' for details of operation.

- Without turning the ignition off, the MIL and warning lamps are not illuminated.
