The adaptive cruise control is supplemented by the Queue Assist function (also called "Queue Assist").
Queue Assistant has the following functions:
- Extended speed range - also below 30 km/h and when stationary
- Change of target
- Automatic braking ceases when stationary
- Automatic activation parking brake.
Note that the lowest programmable speed for the adaptive cruise control is 30 km/h - even though it is capable of following another vehicle down to a standstill, a lower speed cannot be selected.
Extended speed range
In order to activate the cruise control the driver's door must be closed and the driver must be wearing the seatbelt.
The adaptive cruise control can follow another vehicle within the range 0-200 km/h.
Activation of the cruise control below 30 km/h requires a vehicle in front within a reasonable distance.
For shorter stops in connection with inching in slow traffic or at traffic lights driving is automatically resumed if the stops do not exceed about 3 seconds - if it takes longer before the car in front starts moving again then the Adaptive cruise control is set in standby mode with automatic braking. The driver must then reactivate it in one of the following ways:
- Press the steering wheel button .
- Depress the accelerator pedal.
|>||The cruise control will then resume following the vehicle in front.|
Queue Assist can hold the car stationary for a maximum of 4 minutes - then the parking brake is applied and Cruise Control is disengaged.
- The driver has to release the parking brake before the cruise control can be reactivated.
Change of target
If the target vehicle in front suddenly turns then there may be stationary traffic in front.
When the adaptive cruise control is following another vehicle at speeds below30 km/h and changes target from a moving to a stationary vehicle, the cruise control will slow down for the stationary vehicle.
When the cruise control is following another vehicle at speeds in excess of30 km/h and the target is changed from a moving vehicle 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
The adaptive cruise control is disengaged and set in standby mode:
- when the speed is below 5 km/h and cruise control is not sure 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 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
In certain situations, Queue Assist stops automatic braking at a standstill. This means that the brakes are released and the car may start to roll - the driver must therefore intervene and brake the car himself/herself in order to maintain its position.
Queue Assist releases the foot brake and sets the adaptive cruise control in standby mode in the following situations:
- the driver puts his/her foot on the brake pedal
- the parking brake is applied
- the gear selector is moved to P, N or R position
- the driver sets the cruise control in standby mode.
Automatic activation parking brake
In certain situations Queue Assist applies the parking brake in order to keep the car remaining stationary.
This takes place if:
- the driver opens the door or takes off his/her seatbelt
- DSTC is changed from Normal to Sport mode
- Queue Assist has held the car stationary for more than 4 minutes
- the engine is switched off
- the brakes have overheated.
