Operating conditions of hill-start assist
control
When the following four conditions are met,
the hill-start assist control will operate:
●
The shift lever is in a position other than P
or N (when starting off forward/back-
ward on an upward incline).
●
The vehicle is stopped.
●
The accelerator pedal is not depressed.
●
The parking brake is not engaged.
■ 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 moved to P or N.
● The accelerator pedal is depressed.
● The parking brake is engaged.
● Approximately 2 seconds elapse after
the brake pedal is released.
■
Sounds and vibrations caused by the
ABS, brake assist, VSC, TRAC and
hill-start assist control systems
●
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 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 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 malfunction.
■ Reactivation of the TRAC/VSC systems
Even after the TRAC/VSC systems have
been turned off, turning the engine off and
then on again will automatically reactivate
the TRAC/VSC systems.
■
Reactivation of the TRAC system linked
to vehicle speed
When only the TRAC system is turned off,
the TRAC system will turn on when vehicle
speed increases. However, when both
TRAC/VSC systems are turned off, the sys-
tems will not turn on even when vehicle
speed increases.
■ 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 engine off. The EPS system should
return to normal within 10 minutes.
WARNING
■ The ABS does not operate effectively
when
● The limits of tire gripping performance
have been exceeded (such as exces-
sively worn tires on a snow covered
road).
● The vehicle hydroplanes while driving
at high speed on wet or slick roads.
■ Stopping distance when the ABS is
operating may exceed that of normal
conditions
The ABS is not designed to shorten the
vehicle’s stopping distance. Always main-
tain a safe distance from the vehicle in
front of you, especially in the following
situations:
● When driving on dirt, gravel or
snow-covered roads
● When driving over bumps in the road
