the shift lever to D (Drive). Release the

accelerator pedal.
The Hill-start Assist Control(HAC) will
hold the vehicle brakes for up to 2 sec-
onds on grades steeper than 8° uphill.
WARNING
If your vehicle becomes stuck in
snow, mud, sand, etc., then you
may attempt to rock the vehicle free
by moving it forward and backward.
Do not attempt this procedure if
people or objects are anywhere
near the vehicle. During the rocking
operation the vehicle may suddenly
move forward or backward as it
becomes unstuck, causing injury
or damage to nearby people or
objects.
WARNING
The HAC is activated only for about
2 seconds, so when the vehicle is
starting off always depress the
accelerator pedal.
