Changing a set speed
(1) or — (3) buttons briefly or by pressing and holding them:- Press briefly: changes speed in +/– 5 mph (+/– 5 km/h) increments. Each press changes the vehicle's speed by +/– 5 mph (+/– 5 km/h).
- Press and hold: changes the speed +/– 1 mph (+/– 1 km/h) at a time. Release the button when the set speed indicator (4) has moved to the desired speed.
If speed is increased by pressing the accelerator pedal before the button is pressed, the vehicle's speed when the button is pressed will become the set speed assuming that the accelerator pedal is still depressed when the button is pressed.
A temporary increase in speed, such as when passing another vehicle, does not affect the ACC set speed. The vehicle will return to the set speed when the accelerator pedal is released.
The lowest speed that can be set for ACC is 20 mph (30 km/h). However, ACC can monitor and react to the speed of the vehicle ahead down to a standstill.
ACC not installed at the factory
This function can be installed in the vehicle after delivery if it is equipped with the normal cruise control. If ACC was installed after the vehicle was purchased, it will differ from the factory-installed version as follows:
- If the speed of the vehicle ahead goes below 18 mph (30 km/h), ACC disengages (goes into standby mode) and will no longer modulate the brakes. The driver will then have to maintain a safe distance to the vehicle ahead
- The lowest speed at which ACC can be started is 20 mph (30 km/h)
