Start Initiators
WARNING: This page is about a different car, the 2018 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
When the engine stops within an auto stop/start cycle the following conditions will initiate an early restart within the same auto stop/start cycle.
Driver effected start initiators:
- Driver disables the auto stop/start system
- The accelerator pedal is pressed
- Reverse (R) gear is selected on the Transmission Control Switch (TCS)
- Vehicle speed above calibrated threshold 3 km/h (2 mph) (A restart will only occur if the transmission is in Neutral (N) and the driver is present. For example: the driver seatbelt remains fastened and the driver door remains latched).
- Brake booster vacuum below threshold (driver operates brake pedal)
- A higher climate control blower speed is selected
- Windshield demist is activated.
NOTE:
When the brake pedal is released during an auto restart the Anti-lock Brake System (ABS) control module briefly applies the brakes to hold the vehicle stationary until the engine has restarted.
Vehicle system effected start initiators:
- Primary battery cranking capability is near its lower threshold
- Primary battery state of charge is near its lower threshold
- Windshield demist activates
- The passenger compartment temperature decreases below or increases above the selected thresholds.
Environmental effected start initiators:
- Ambient air temperature rises above 40°C (104°F)
- Ambient air temperature falls below 0°C (32°F)
The maximum engine stop duration is 270 seconds, the vehicle will restart after this duration.
