Adaptive Cruise Control (ACC) – Queue Assist

Queue Assist is an added ACC feature that is linked to your vehicle's automatic transmission.

Introduction

Queue Assist is an added ACC feature that is linked to your vehicle's automatic transmission.

Queue Assist consists of the following functions:

  • Enhanced speed interval (including when the vehicle is at a complete stop or is moving at speed below 18 mph (30 km/h))
  • Automatic standby mode when ACC changes target vehicles
  • No automatic braking when at a standstill
  • The parking brake is applied automatically

Please note that the lowest speed that can be set is 18 mph (30 km/h), although ACC can maintain a set speed/distance to a vehicle ahead down to a standstill. Queue Assist consists of the following features:

Enhanced speed interval

 Note

The driver's door must be closed and the driver's seat belt must be fastened before ACC can be put in active mode. If the driver's seat belt is taken off or if the driver's door is opened, ACC will return to standby mode.

Your vehicle can maintain the set time interval to the vehicle ahead at any permissible speed, including a complete stop.

In order to activate ACC at speeds below 18 mph (30 km/h):

  • The vehicle ahead must be within a reasonable distance (not farther away than approx. 100 ft/30 meters)
  • The lowest speed that can be selected is 18 mph (30 km/h), although ACC will also help maintain the set time interval to the vehicle ahead at lower speeds, including a complete stop.

During short stops (less than approximately 3 seconds) in slow-moving traffic, your vehicle will begin moving again automatically as soon as the vehicle ahead begins to move.

If it takes more than 3 seconds for the vehicle ahead to begin moving, ACC will be automatically go into standby mode.

The driver will then have to reactivate ACC in one of the following ways:

  • By pressing Ikon farthållare 5
  • By accelerating up to at least 3 mph (4 km/h). ACC will then resume following the vehicle ahead.

Your vehicle will then resume following the vehicle ahead at the set time interval.

 Note

ACC can remain active and keep your vehicle at a standstill for up to 4 minutes. After 4 minutes have elapsed, the parking brake will be engaged and ACC will go into standby mode.

To reactivate ACC, the driver must release the parking brake (see Parking brake – general information).

Automatic standby mode when ACC changes target vehicles

If the vehicle ahead turns suddenly, there may be a stationary vehicle ahead

The following only applies at speeds below approximately 18 mph (30 km/h):

If ACC changes target vehicles (the vehicle that the radar sensor has detected) from a moving vehicle to a stationary one, the system will apply the brakes in your vehicle.

 Warning

At speeds above 18 mph (30 km/h), ACC will not react to a stationary vehicle and apply the brakes but will instead accelerate to the previously set speed. The driver must actively apply the brakes to stop the vehicle.

ACC disengages and goes into standby mode if:

  • Your vehicle's speed goes below 10 mph (15 km/h) and ACC cannot determine if the target object is a stationary vehicle or some other type of object such as e.g., a speed bump.
  • Your vehicle's speed goes below 10 mph (15 km/h) and the vehicle ahead turns so that ACC no longer has a target vehicle to follow.

No automatic braking when at a standstill

In certain situations, ACC will no longer apply the brakes and go into standby mode while the vehicle is not moving. This means that the driver will have to apply the brakes.

This happens if:

  • The driver presses the brake pedal
  • The parking brake is activated
  • The gear selected is moved to P, N or R
  • The driver presses the Ikon farthållare 4 button to put ACC in standby mode

The parking brake is applied automatically

In certain situations, ACC will apply the parking brake in order to continue keeping the vehicle at a standstill.

This happens if:

  • The driver opens the door or takes off his/her seat belt
  • The stability system is put in Sport mode (see Stability system – operation)
  • ACC has kept the vehicle at a standstill for more than 2 minutes
  • The engine has been switched off
  • The brakes have overheated
