Land Rover Defender: Auto stop/start

AUTO STOP/START

Always disable the auto stop/start system before wading. Failure to do so could cause damage to the vehicle.

The auto stop/start system is designed to improve fuel efficiency. The system automatically activates when the vehicle's ignition is switched on. Unless it is required to support other vehicle systems, the engine switches off when the vehicle is stationary, e.g., at traffic lights. When the engine stops, it is referred to as an auto stop.

When On demand hold is not active and the brake pedal is released, or a drive gear is selected, the engine automatically restarts. When the engine restarts, it is referred to as an auto start.

Operation of the auto stop/start system is indicated by a status icon in the instrument panel.

Note: When activated, the auto stop/start system does not always stop the engine when the vehicle is stationary. The system may also restart the engine before setting off.

Under certain conditions, the auto stop/ start system also switches off the engine while the vehicle is moving.

TRIGGERING AN AUTO STOP

To trigger an auto stop, drive forward with Drive (D) or Sport (S) selected, and stop the vehicle. Fully press the brake pedal to make sure the vehicle is stationary.

The following conditions inhibit an auto stop:

• The external temperature is less than approximately 25ºF (-4ºC).
• The external temperature is more than approximately 104ºF (40ºC).
• The engine or other vehicle systems have not reached their optimum operating temperatures.
• The driver's seat belt is unbuckled.
• Demand from the climate control system requires the engine to be running, e.g., when in defrost mode.
• The vehicle's battery charge is low.
• The auto stop/start system is deactivated.
• After reversing, the vehicle's speed has not exceeded 10 mph (16 km/h).

The instrument panel displays an information lamp when the vehicle is stationary and the auto stop/start system is active, but operation is inhibited.

TRIGGERING AN AUTO START

To trigger an auto start, release the brake pedal with Drive (D) or Sport (S) selected.

The engine also restarts if one of the following occurs:

• The auto stop/start system is deactivated.
• Reverse (R) is selected.
• Demand from the climate control system increases.
• The vehicle begins to move.
• The vehicle's battery charge becomes low.
• The accelerator pedal is pressed.

DEACTIVATING AUTO STOP/ START

Press the auto stop/start button to deactivate the auto stop/start system.

Note: The auto stop/start system is automatically deactivated if low range, All Terrain Progress Control (ATPC), or Hill Descent Control (HDC) is selected. The system is also deactivated if certain terrain response special programs are selected by the driver, or selected by the AUTO driving program.

When the auto stop/start system is deactivated, a status icon is displayed.

The instrument panel displays the message Auto Stop/Start not available if the icon is selected while the system is unable to operate.

Note: The auto stop/start system automatically reactivates the next time the vehicle's ignition is switched on

AUTO STOP ON THE MOVE

Vehicles with a 48v system are equipped with an auto stop on the move feature.

The auto stop on the move feature switches off the engine while the vehicle is moving if:

• The vehicle is traveling at less than approximately 1 mph (2 km/h), and:
• The brake pedal is pressed.

When the brake pedal is released, the engine automatically restarts.

Operation of the auto stop on the move feature is indicated by a status icon in the instrument panel.

The auto stop on the move feature is deactivated if auto stop/start is deactivated.

DRIVER EXIT

During an auto stop, the driver exit feature prevents the vehicle from being inadvertently left in a driveable condition.

If the feature detects that the driver is not present, it automatically switches off the vehicle's ignition system. Once the vehicle's ignition is switched off, the vehicle can be locked, if required.

If the vehicle is left in a driveable condition with the engine running, the driver exit feature does not prevent the vehicle from moving. Failure to make sure the vehicle is left in a safe condition could lead to serious injury or death.

48v system vehicles only

If Park (P) is selected, the driver exit feature switches the vehicle's ignition off when all the following conditions exist:

• The vehicle is in an auto stop.
• The driver's seat belt is unbuckled.
• All foot pedals are released.
• The driver's door is opened.

Other vehicles

If Park (P) is selected, the driver exit feature switches the vehicle's ignition off when all the following conditions exist:

• The vehicle is in an auto stop.
• The driver's seat belt is unbuckled.
