STARTING AND DRIVING

HILL-ST ART ASSIST CONTROL
SYSTEM
The hill-start assist control system assists you in starting
to move up a steep or slippery hill. When you start to move
up the hill slope, the system helps to prevent the vehicle
from rolling backward in the interval while you move your
foot from the brake pedal to the accelerator pedal.
CAUTION
Do not rely excessively on the hill-start assist control
system. The vehicle may not be able to start
smoothly on road surfaces or off-road surfaces such
as extremely steep slopes or icy roads, on which
sliding can occur very easily.
Do not use the hill-start assist control system to stop
the vehicle. This system is not designed as a function
for stopping the vehicle on a uphill slope.
The hill-start assist control system will operate for 5
seconds maximally when all of the following conditions
apply.
When the transmission is in any of positions “D”, “4”,
“3”, “2” or “L”
When the brake pedal is not depressed
The system is designed to operate when the vehicle is starting
on an uphill slope; therefore, if the transmission is in “P” or “N”
it will not operate. It will not operate either if the vehicle starts
to move in reverse on a slope with the transmission in the “R”.
Slip indicator light
When the hill-start assist control system is operating, the slip
indicator light flashes and an alarm sounds intermittently. At
the same time, the stop lamps and high mounted stoplight are
lit.
