General

All markets have a common cruise control system. The cruise control system, when activated, regulates vehicle speed. The system consists of an electrical sub-system and a mechanical sub-system.

The electrical sub-system consists of the following components: l Cruise control master switch (on/off switch). l SET+ switch. l RES switch. l Cruise control ECU. l Vacuum pump assembly. l Brake pedal switch. l Clutch pedal switch (manual gearbox only). l SLABS ECU (speed signal). l BCU (brake pedal switch and automatic gearbox gear selector lever position signal).

The mechanical sub-system consists of the following components: l Pneumatic actuator. l Vacuum pump.

The cruise control ECU controls the cruise control system. It is located on the right hand A post.

The system has diagnostic capabilities through TestBook.

WARNING: To avoid the risk of losing control of the vehicle, do not use cruise control on winding, snow covered or slippery roads, or in traffic conditions where a constant speed cannot be safely maintained. In these conditions and at any time the system is not being used, ensure the cruise control switch is OFF.

Cruise control master switch

The cruise control master switch switches the system on and off. When the cruise control master switch is on, an LED within the switch illuminates. If the cruise control master switch is off, cruise control will not operate. The switch provides a 12 Volt feed to the cruise control ECU.

The cruise control master switch is located on the instrument panel near the steering column.
