6-1. Features of the safe driving support functions
■ Operating conditions of hill-start assist
control
When the following four conditions are met,
the hill-start assist control will operate:
● The shift position is in a position other
than P or N (when starting off for-
ward/backward on an upward incline)
● The vehicle is stopped
● The accelerator pedal is not depressed
● The parking brake is not engaged
● Power switch is turned to ON
■ Automatic system cancelation of
hill-start assist control
The hill-start assist control will turn off in any
of the following situations:
● The shift position is shifted to P or N
● The accelerator pedal is depressed
● The brake pedal is depressed and the
parking brake is engaged
● A maximum of 2 seconds have elapsed
after the brake pedal is released
● Power switch is turned to OFF
■ Sounds and vibrations caused by the
ABS, brake assist, VSC, TRAC and
hill-start assist control systems
● A sound may be heard from the motor
compartment when the brake pedal is
depressed repeatedly, when the EV sys-
tem is started or just after the vehicle
begins to move. This sound does not indi-
cate that a malfunction has occurred in
any of these systems.
● Any of the following conditions may
occur when the above systems are oper-
ating. None of these indicates that a mal-
function has occurred.
• Vibrations may be felt through the vehicle
body and steering.
• A motor sound may be heard also after
the vehicle comes to a stop.
• The brake pedal may pulsate slightly after
the ABS is activated.
• The brake pedal may move down slightly
after the ABS is activated.
■ ECB operating sound
ECB operating sound may be heard in the
following cases, but it does not indicate that
a malfunction has occurred.
● Operating sound heard from the motor
compartment when the brake pedal is
operated.
● Operating sound heard from the motor
compartment when one or two minutes
passed after the stop of the EV system.
■ Active Cornering Assist operation
sounds and vibrations
When the Active Cornering Assist is oper-
ated, operation sounds and vibrations may
be generated from the brake system, but
this is not a malfunction.
■ Reduced effectiveness of the EPS sys-
tem
The effectiveness of the EPS system is
reduced to prevent the system from over-
heating when there is frequent steering
input over an extended period of time. The
steering wheel may feel heavy as a result.
Should this occur, refrain from excessive
steering input or stop the vehicle and turn
the EV system off. The EPS system should
return to normal within 10 minutes.
■ Automatic reactivation of TRAC and
VSC systems
After turning the TRAC and VSC systems
off, the systems will be automatically
re-enabled in the following situations:
● When the power switch is turned off
● If only the TRAC system is turned off, the
TRAC will turn on when vehicle speed
increases
If both the TRAC and VSC systems are
turned off, automatic re-enabling will not
occur when vehicle speed increases.
■ Operating conditions of Active Corner-
ing Assist
The system operates when the following
occurs.
● TRAC/VSC can operate
● The driver is attempting to accelerate
while turning
● The system detects that the vehicle is
drifting to the outer side
● The brake pedal is released
