Cold Start Neutral

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

NOTE: The Cold Start Neutral (CSN) function has been introduced on 8HP70 transmissions for all petrol engine variants from 18MY onwards.

Cold Start Neutral (CSN) is a software function. The software function operates when the engine is cold. When the driver selects drive or sport with their foot on the brake, the transmission delays the engagement of gear. This allows the engine speed to remain high. If the driver releases the brake the engine speed reduces to idle and the transmission engages the gear. The function is also exited and the transmission engages the gear if while the driver has their foot on the brake the engine reaches operating temperature.

Previous transmissions would engage the gear when the driver selected drive or sport. This resulted in a noticeable gear engagement. The introduction of CSN will delay gear engagement until either the driver releases the brake or the engine reaches operating temperature. The purpose of the function is to assist in maintaining engine management control during the warm up cycle. Some customers may indicate that there is a delay in gear selection or an elevated engine speed (circa 1600rpm) but this is normal with CSN.
