Suspend Speed Control
2016 Jaguar XJR BaseSECTION Suspend Speed Control
Suspending speed control means speed control has been deactivated without loss of the memory speed. In all suspend events the memory speed is maintained.
Speed control is suspended when one of the following occurs:
- Vehicle speed falls below 20 mph (32 km/h).
- The brake pedal is pressed.
- The CANCEL switch is operated.
- 'N' (Neutral), 'R' (Reverse) or 'P' (Park) is selected on the TCS.
- If the accelerator pedal is used to accelerate beyond the set speed for too long (more than 5 minutes).
- Engine speed too high (cancel limit set just below red line).
- The ABS control module activates ETC (Electronic Traction Control) or DSC (Dynamic Stability Control).
- System error causes shut-off.
NOTE:
In the event that a memory speed has been lost during a driving cycle, confirm with the customer if the 'Cruise Not Available' message was observed. Loss of memory speed implies a fault has occurred. The massage 'Cruise Not Available' may only be displayed on demand for some errors, so speed control needs to be requested via the SET "+" switch to drive the message.
