Brake functions
The vehicle's standard braking features are aug- mented by a number of auxiliary help functions.
In addition to the wheel brakes and the parking brake, the vehicle is equipped with several auto-matic brake assist functions. These systems helpthe driver by e.g., keeping the vehicle stationarywhen the brake pedal is not depressed (at a traf-fic light or intersection), when starting up a hill orwhen driving down a hill. These systems include: • Auto-hold brakes
• Hill Start Assist
• Braking assist after a collision
• Hill Descent Control

Auto-hold brake function
With the Auto-hold brake function, the driver can release the brake pedal and the brakes willremain applied, for example, when the vehiclehas stopped at a traffic light or intersection.
When the vehicle is no longer moving forward, Auto-hold applies the brakes automatically, eitherusing the normal brakes or the parking brake.The brakes will be released when the acceleratorpedal is depressed. If the driver's door is opened or the engine is turned off, the parking brake will be applied auto-matically. Auto-hold is deactivated when the transmission is in neutral or if the driver's door is open and theseat belt is unbuckled.

Brake assist system The Brake Assist System (BAS) increases brak- ing force, thereby helping reduce braking dis-tance.
The system monitors the driver's braking habits and increases braking force when necessary.Brake force can be increased up to the point atwhich the ABS system is activated. The functionis deactivated when pressure on the brake pedaldecreases.

Braking effect after a collision
In certain types of collisions, the vehicle's brakes are applied to help prevent or mitigate a secon-dary collision.
Maintaining control of the vehicle after a collision may be difficult. To help avoid or mitigate theeffect of a secondary collision, the brakes areapplied automatically to help bring the vehicle toa stop. The brake lights and hazard warning flashers will be activated and the flashers will remain on afterthe vehicle has come to a standstill. The parkingbrake will then be applied automatically. In a situation where stopping the vehicle may not be desirable, the driver can override this systemby pressing the accelerator pedal. This feature can only function if the brake system is intact after the collision.

Hill Start Assist
Hill Start Assist (HSA) helps prevent the vehicle from rolling backwards when starting up a hill. Ifyou are backing up a hill, HSA helps prevent thevehicle from rolling forward.
HSA makes it easier to start or back up on a hill by retaining pressure on the brake pedal for sev-eral seconds after the pedal has been released inorder to keep the vehicle at a standstill. The brakes will be released after several seconds or when the driver presses the accelerator pedal. HSA is available even if the Auto-hold braking function is turned off.

NOTE
•A faint sound from the parking brake's electric motor can be heard when theparking brake is being applied. Thissound can also be heard during the auto-matic function check of the parkingbrake.
• The brake pedal will move slightly whenthe electric parking brake is applied orreleased.
If the vehicle is not moving when the parking brake is applied, only the rear wheels are affec-
