Intelligent Speed Limiter

WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

The Intelligent Speed Limiter (ISL) indicator will illuminate when the ISL has been selected. The ISL restricts the vehicle's maximum speed to the current legal applicable road speed limit. The speed limit information is provided by the navigation system and Traffic Sign Recognition (TSR). If a valid speed limit is not available, ISL will be deactivated and the limiter will default to Automatic Speed Limiter (ASL).

The ISL system will only respond to speed settings from the lowest possible, 30 km/h (19 mph) and maximum speed limit 130 km/h (80 mph). Below this speed range a message, SET POINT OUT OF RANGE will be displayed in the message center. Any TSR above the maximum speed limit range, the ISL will set the speed limiter to unlimited.

Adjustment, to a maximum of 10 km/h (6 mph) above and below the legal speed limit, can be set operating the speed control SET '+' and '-' switches. If a legal speed limit is detected higher or lower than the current vehicle speed, the ISL will adjust the speed to a safe level. Operating the 'RESUME' switch will enable the vehicle to reach this limit at a faster rate.

If the vehicle speed exceeds the speed limit by more than 3.5 km/h (2 mph) a warning will be displayed in the message center. If the speed exceeds the speed limit by 7 km/h (5 mph) for more than 4 seconds a chime will sound.

Operating the 'CANCEL' switch will put the ISL into stand-by mode, the ISL is re-activated by operating the 'RESUME' switch.

If the driver operates the accelerator pedal to maximum, ISL will be overridden.

If the vehicle is equipped with ASL and ISL systems:

If the ASL system was in use when the ignition was switched off, the selected ASL mode is saved. The ASL activates again when the ignition is switched back to the on position (Power Mode 6). However the speed settings are not remembered and will have to be set again.
If the ISL system was in use when the ignition was turned off. When the ignition is turned back on (Power Mode 6), the ISL is deactivated and the speed limiter defaults to the ASL operating mode.
