Adaptive Cruise Control* - queue assistance
The adaptive cruise control (ACC – Adaptive Cruise Control) helps the driver to maintain an even speed combined with a pre-selected time interval to the vehicle ahead.
Queue assistance also provides the adaptive cruise control with enhanced functionality at speeds lower than 30 km/h (20 mph).
In cars with automatic gearbox the adaptive cruise control is supplemented with the queue assistance function (also referred to as "Queue Assist").
- Extended speed range - also at lower than 30 km/h (20 mph) and at stationary
- Change of target
- Automatic braking ceases when stationary
Note that the lowest programmable speed for the adaptive cruise control is 30 km/h (20 mph) - even though the cruise control is capable of following another vehicle down to 0 km/h, a lower speed cannot be selected.
Extended speed range
With an automatic gearbox, the adaptive cruise control can follow another vehicle within the range 0-200 km/h (0-125 mph).
- Press the steering wheel button .
- Depress the accelerator pedal.
|>||The cruise control will then resume following the vehicle in front.|
The Queue Assist function can keep the car stationary for a maximum of 4 minutes - then the brakes release.
See more information under the heading "Termination of automatic braking at a standstill".
Change of target
When the adaptive cruise control is following another vehicle at speeds lower than 30 km/h (20 mph) and the target is changed from a moving vehicle to a stationary vehicle, the cruise control will brake for the stationary vehicle.
When the adaptive cruise control is following a vehicle in front at speeds in excess of 30 km/h (20 mph) and the target is changed from a vehicle in front to a stationary vehicle, the cruise control will ignore the stationary vehicle and instead select the stored speed.
- The driver must intervene him/herself and brake.
Automatic standby mode with change of target
- when the speed is below 5 km/h (5 mph) and the cruise control is uncertain whether the target object is a stationary vehicle or some other object, e.g. a speed bump.
- when the speed is below 5 km/h (5 mph) and the vehicle in front turns off so the cruise control no longer has a vehicle to follow.
Termination of automatic braking at a standstill
- the driver opens the door
- the driver takes off his seatbelt.
This means that the brakes are released and the car will start to roll - the driver must therefore intervene and brake the car himself in order to maintain its position.
Queue Assist can keep the car stationary for a maximum of 4 minutes - then the brakes release.
The driver's attention is drawn to this over several stages, with increasing intensity:
- Acoustic alarm (pinging) and text message.
- A warning lamp in the windscreen also starts to flash.
- "Stabbing" braking occurs.
For more information on symbols, messages and their meaning, see the section Symbols and messages in the display.
- the driver puts his/her foot on the brake pedal
- the gear selector is moved to P, N or R position
- the driver sets the cruise control in standby mode
- the parking brake is applied.
