Some Toyota vehicles include 
a hill-start assist function
as an integral part of their 
active safety systems 
along with ABS, 
Electronic Brake Distribution, 
Brake Assist, 
traction control and enhanced 
Vehicle Stability Control.
The hill-start assist function 
helps prevent the vehicle
from rolling backwards 
when starting off on an incline.
For example, when a driver
tries to drive forward 
from a stop on an incline 
without hill start assist 
control, 
the vehicle may start to 
roll backwards while the 
driver's foot 
moves from the brake pedal 
to the accelerator pedal.
This may result in a 
hurried pedal transition, 
making it challenging 
to drive away smoothly.
To prevent that occurrence,
hill-start assist temporarily 
applies the brakes to 
all four wheels,
preventing the vehicle 
from rolling backwards. 
The driver can then pull away 
in a smooth and relaxed manner.
In some models, operation 
of the system is automatic.
It requires no action 
by the driver and 
provides no indication,
either by an indicator lamp or 
a sound, that it is operating. 
It simply does the job.
In other models,
operation of hill-start assist 
control must be initiated 
by the driver. 
It can be activated,
after the vehicle has been 
stopped on an uphill slope, 
by depressing the brake pedal 
a little further. 
A buzzer then will sound
one time [one short beep]
to indicate that the system
is activated,
and the slip indicator 
in the instrument cluster 
will start flashing.
On those models, if the slip 
indicator does not flash
and the buzzer does not sound, 
slightly reduce the pressure
on the brake pedal 
(without allowing the vehicle 
to roll back)
and then firmly depress 
the pedal again to 
activate the system.
Hill-start assist may be 
activated when:
The vehicle is stopped 
on an incline.
The shift lever is in a 
position other than “P” or "N."
The parking brake 
is not applied.
The accelerator pedal 
is not depressed.
Once activated, the brakes 
automatically will remain 
applied for a few seconds
after the driver releases 
the brake pedal,
permitting time for the 
driver's foot to move to the 
accelerator pedal 
while the vehicle 
remains stopped. 
During this period the rear 
brake lights will remain on.
Hill-start assist will be 
deactivated
and the brakes released 
when the vehicle drives away.
Hill-start assist will be 
canceled automatically
and the buzzer 
may sound twice [two short beeps] if:
No attempt is made 
to drive the vehicle
within approximately 
two seconds of releasing 
the brake pedal.
The shift lever is 
moved to “P,”
The parking brake 
is applied, or
The brake pedal is 
depressed again
It should be noted that, 
unlike the parking brake, 
which is a separate 
braking system, 
hill start assist control 
is not intended to hold 
the vehicle stationary 
for an extended period of time
and should not be used 
for that purpose. 
It should be noted that 
hill-start assist control
is a supplementary 
driver assistance system. 
It is not a substitute for 
good driving practices.
