Hill-Start Assist Control (Hac); Vehicle Stability Management (Vsm) System - Kia Carnival 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 automatically for about
2 seconds.
The brakes are released when the
accelerator 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 suffi -
cient to prevent your vehicle from
rolling backward and causing an
accident. Don't release the brake
pedal until you are ready to acceler -
ate forward.
Vehicle Stability Management
(VSM) system
The Vehicle Stability Management
(VSM) provides further enhance -
ments to vehicle stability and steer -
ing responses under the following
condition:
when driving on a slippery road or
when a change in the coefficient
of friction between left and right
wheels is detected.
WARNING
Tyre/Wheel size
When replacing tyres and wheels,
make sure they are the same size
as the original tyres and wheels
installed. Driving with varying tyre
or wheel sizes may diminish any
supplemental safety benefits of the
VSM system.
VSM operation
When the VSM is operating properly,
you can feel a slight pulsation in the
vehicle and/or abnormal steering
responses (Electronic Power Steer -
ing (EPS)). This is only the effect of
brake and EPS control and indicates
nothing unusual.
