System Functions: Gradient
WARNING: This page is about a different car, the 2003 Jaguar XJR, 2002 Jaguar XJR, and 2001 Jaguar XJR. However, it is still accessible from the selected car via links, so may be relevant.
The gradient function is intended to enhance vehicle driveability when climbing a gradient or towing. The TCM will implement the function when increased driving resistance is detected, and provides enhanced driveability, additional cooling and/or increased performance as appropriate.
