STARTING AND DRIVING
* Option/accessory.405
Hill Start Assist
The function for assisting when starting the vehi-
cle on inclines (HSA4) helps prevent the vehiclefrom rolling backward when starting on an uphillgradient. When backing up a hill, HSA helpsprevent the vehicle from rolling forward.
The function retains pressure from the brakepedal in the brake system for several secondsafter the brake pedal has been released.
This temporary braking effect is released after afew seconds or when the driver begins driving.
Hill Start Assist is available even when the Auto-hold brake function is switched off.

Braking assist after a collision
In a collision in which the activation level isreached for the pyrotechnic seat belt tensionersor airbags, or if a collision with a large animal isdetected, the vehicle's brakes will be automati-cally activated. This function is intended to helpprevent or reduce the effects of any subsequentcollision.
After a serious collision, it may no longer be pos-sible to control and steer the vehicle. In order toavoid or mitigate a possible further collision witha vehicle or an object in the vehicle's path, thebrake assist system is activated automatically tohelp stop the vehicle safely.
The brake lights and hazard warning flashers areactivated during braking. When the vehicle hasstopped, the hazard warning flashers will con-tinue to flash and the parking brake will beapplied.
If braking is not appropriate, e.g. if there is a riskof being hit by passing traffic, the driver can over-ride the system by depressing the acceleratorpedal.
This function assumes that the brake system isintact after a collision.
Brake assist is part of the Rear Collision Warningand Blind Spot Information safety systems.
