STARTING AND DRIVING
Stopping the Engine
WARNING: The gearbox has no Park
position to lock the gears. The parking
brake is the only means of preventing
the vehicle moving.
NOTE: Do not depress the accelerator
pedal when stopping the engine.
Do not switch the engine off
immediately after high speed/high load
running. Allow it to run for 2 minutes so
the engine temperature returns to
normal.
NOTE: When parking on steep downhill
slopes, turn the front wheels towards the
kerb. When parking on steep uphill
slopes, turn the front wheels away from
the kerb.
NOTE: There is no special procedure for
stopping when the electric motor is in
use.
1. Pull the parking brake switch upwards to
apply.

NOTE: If the parking brake is not applied
manually, it will apply automatically
when the powertrain stops, and the
driver's door is open. Automatic
application can be overridden by holding
the parking brake switch in the down
position whilst opening the driver's door.
2. Select neutral.
3. Press the START/STOP button. The
engine stops, the vehicle enters the
Accessory state, see Vehicle Electrical
Status, page 2.2. The immobiliser is
activated.
NOTE: If the START/STOP button is
pressed for more than a second, the
vehicle will enter the Awake state for a
brief time before returning to Accessory
state if no further inputs are made, see
Vehicle Electrical Status, page 2.2.
