Range Rover Sport. Manual — part 82
Left hand drive illustrated, right hand drive on opposite side of centre console.
9. Lift out the cup holder inserts from the centre console
10. Remove the access panel from the centre console.
11. Locate the electric parking brake release cable, insert a suitable tool through the cable eye and pull the cable upwards
to release the parking brake.
CAUTION: The electric parking brake will not function until electrical power is restored. It will, therefore, be
necessary to chock the wheels when vehicle is at a standstill.
WARNING: Do not release the parking brake until towing is about to commence. Whilst towing, do not
attempt to remove the ignition key and do not turn the key to any position other than 'II'. With the engine switched
off, the power assisted steering system and brake booster will be inoperative thereby resulting in an increase in
the effort required to turn the steering wheel and apply the brakes.
CAUTION: The vehicle tow connections should only be used in normal road conditions, 'snatch' recovery
must be avoided.
On completion of 4 wheel towing
1. Apply the parking brake or if electrical power is not available, securely chock the wheels.
2. Detach towing equipment from towing/lashing eyes.
3. Fit the towing eye access panel and secure the toggle fasteners.
Transporting by trailer
CAUTION: Use the towing/lashing eyes at the front and rear of the vehicle, DO NOT secure lashing hooks or
restraints to any other part of the vehicle.
Position the vehicle, apply the parking brake and select 'N' - Neutral on the automatic transmission selector lever
CAUTION: If electrical power is not available and the parking brake is released, it will not be possible to re-
apply the parking brake. It will, therefore be necessary to select 'P' Park and ensure that the vehicle wheels are
adequately chocked to prevent vehicle movement.
Ride and Handling Optimization
Overview
Ride and handling optimization incorporates the terrain response system which links a number of modules around the
vehicle to give the best combination of settings in the different systems.
For information on the description and operation of the system:

Inspection and Verification
1 . Verify the customer concern.
2 . Visually inspect for obvious mechanical or electrical faults.

3 . If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the
next step.
4 . Use the approved diagnostic system or a scan tool to retrieve any diagnostic trouble codes (DTCs) before moving onto
the symptom chart or DTC index.

Make sure that all DTCs are cleared following rectification.
Symptom chart
Because the overall function of the system is dependent on sub-systems, it is possible to misinterpret displays in the
message center as being terrain response faults when they are actually a result of a fault in one of the sub-systems.
Refer to the table below for help in deciding when to investigate terrain response faults and when the fault is likely to be in a
sub-system.
