■Operating conditions of hill-start
assist control
When the following four conditions are
met, the hill-start assist control will oper-
ate:
●The shift lever is in a position other
than R when starting off forward on an
upward incline, or the shift lever is in
R when starting off backward on an
upward incline.
●The vehicle is stopped
●The accelerator pedal is not
depressed
●The parking brake is not engaged
●Engine 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 lever is shifted to R when
starting off forward on an upward
incline, or the shift lever is shifted to
other than R when starting off back-
ward on an upward incline.
●The accelerator pedal is depressed
●The parking brake is engaged
●2 seconds at maximum elapsed after
the brake pedal is released
●Engine switch is turned to OFF
■Sounds and vibrations caused by
the ABS, brake assist, VSC, TRC
and hill-start assist control sys-
tems
●A sound may be heard from the
engine compartment when the brake
pedal is depressed repeatedly, when
the engine is started or just after the
vehicle begins to move. This sound
does not indicate that a malfunction
has occurred in any of these systems.
●Any of the following conditions may
occur when the above systems are
operating. None of these indicates
that a malfunction 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.
■EPS operation sound
When the steering wheel is operated, a
motor sound (whirring sound) may be
heard. This does not indicate a malfunc-
tion.
■Automatic reactivation of TRC and
VSC systems
After turning the TRC and VSC systems
off, the systems will be automatically re-
enabled in the following situations:
●When the engine switch is turned off
●If only the TRC system is turned off,
the TRC will turn on when vehicle
speed increases.
If both the TRC and VSC systems are
turned off, automatic re-enabling will
not occur when vehicle speed
increases.
■Reduced effectiveness of the EPS
system
The effectiveness of the EPS system is
reduced to prevent the system from
overheating 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 engine off.
The EPS system should return to nor-
mal within 10 minutes.
■Operating conditions of emergency
brake signal
When the following conditions are met,
the emergency brake signal will oper-
ates:
●The emergency flashers are off
●Actual vehicle speed is over 55 km/h
(35 mph)
●The system judges from the vehicle
deceleration that it is a sudden brak-
