僅 Hill-Start Assist Control (Hac); 僅 Multi-Collision Brake (Mcb) - Kia Sorento 2023 Manual

Driving your vehicle
Hill-start Assist Control (HAC)
A vehicle has the tendency to roll back
on a steep hill when it starts to go after
stopping. The Hill-start Assist Control
(HAC) prevents the vehicle from rolling
back by applying the brakes automati-
cally for about 2 seconds.
The brakes are released when the accel-
erator pedal is engaged or after about 2
seconds.
The HAC is activated only for about 2
seconds, so when the vehicle is starting
off always engaged the accelerator
pedal.
WARNING
Maintaining Brake Pressure on Incline
HAC does not replace the need to apply
brakes whilst stopped on an incline.
Whilst stopped, make sure you maintain
brake pressure sufficient to prevent your
vehicle from rolling backward and caus-
ing an accident. Don't release the brake
pedal until you are ready to accelerate
forward.
Multi-Collision Brake (MCB) (if
equipped)
Multi-Collision Brake controls the brake
automatically in the event of an accident
where the air bag deploys to reduce the
risk of additional accidents that may
occur.
System operation
僅 From the time the air bag deploys,
Multi-Collision Brake monitors the
depression intensity of the brake
pedal and accelerator pedal for a
short period. The system operates
when the following conditions are
met:
- Vehicle speed is under 180 km/h
(112mph) at the time of collision.
- The brake pedal and accelerator
pedal is hardly depressed.
僅 When the driver steps on the brake
pedal over a certain level whilst Multi-
Collision Brake System is active, the
braking power takes priority over
automatic braking by Multi-Collision
Brake system. However, if the driver
takes his/her foot off the brake pedal,
Multi-Collision Brake system will
maintain automatic braking.
System off
Multi-Collision Brake is cancelled in the
following situations:
僅 The accelerator pedal is depressed
over a certain level.
僅 The vehicle stops.
僅 There is malfunction of ESC (Elec-
tronic Stability Control) or electronic
devices.
僅 Ten seconds have passed since the
brake has been controlled automati-
cally by Multi-Collision Brake system.
WARNING
僅 Multi-Collision Brake decreases vehi-
cle speed after a collision and reduces
the risk of a second collision, but it
does not prevent a second collision.
You may drive away from the collision
spot to avoid other dangerous situa-
tions by depressing the accelerator
pedal.
僅 After the vehicle is stopped by Multi
Collision Brake, the system stops con-
trolling the brakes. Depending on the
situation, the driver should depress
the brake or the accelerator pedal to
prevent a further accident.
