Change of target
If the target vehicle in front suddenly turns then there may be stationary traffic in front.
When Pilot Assist is following another vehicle at speeds below30 km/h (20 mph) and changes target from a moving to a stationary vehicle, Pilot Assist will slow down for the stationary vehicle.
When Pilot Assist is following another vehicle at speeds in excess ofapprox. 30 km/h (20 mph) and the target is changed from a moving vehicle to a stationary vehicle, Pilot Assist will ignore the stationary vehicle and instead select the stored speed.
- The driver must then intervene him/herself and brake.
Automatic standby mode with change of target
Pilot Assist is disengaged and set in standby mode:
- when the speed is below 5 km/h (3 mph) and Pilot Assist 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 (3 mph) and the vehicle in front turns off so the Pilot Assist no longer has a vehicle to follow.
For shorter stops in connection with inching forward 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 Pilot Assist is set in standby mode with automatic braking.
Pilot Assist is reactivated in the following way:
- Press the steering wheel button .
- Depress the accelerator pedal.
Pilot Assist resumes following the vehicle ahead if it starts moving forward within 6 seconds.
Pilot Assist can hold the car stationary for a maximum of 5 minutes - then the parking brake is applied and the function is disengaged.
Before Pilot Assist can be reactivated, the parking brake must be released.
Cessation of automatic braking
In some situations, automatic braking ceases on coming to a standstill and Pilot Assist is set in standby mode. 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 to keep it stationary.
This may take place 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 Pilot Assist in the standby mode.
Automatic activation of parking brake
In certain situations the parking brake is applied to keep the car stationary.
This takes place if Pilot Assist is holding the car stationary with the foot brake and:
- the driver opens the door or takes off his/her seatbelt
- Pilot Assist has kept the car stationary for more than approx. 5 minutes
- the brakes have overheated
- the engine is switched off.
