Driving
Q Sounds and vibrations caused by the
Multi Terrain ABS, brake assist, VSC,
Trailer Sway Control, Active TRC and
hill-start assist control systems
O 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.
O 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 vehi-
cle body and steering.
• A motor sound may be heard also after
the vehicle comes to a stop.
Q ECB operating sound
ECB operating sound may be heard in the
following cases, but it does not indicate that
a malfunction has occurred.
O Operating sound heard from the engine
compartment when the brake pedal is
operated.
O Motor sound of the brake system heard
from the front part of the vehicle when
the driver’s door is opened.
O Operating sound heard from the engine
compartment when one or two minutes
passed after the stop of the engine.
Q EPS operation sound
When the steering wheel is operated, a
motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
Q Automatic reactivation of Active TRC,
Trailer Sway Control and VSC systems
After turning the Active TRC, Trailer Sway
Control and VSC systems off, the systems
will be automatically re-enabled in the fol-
lowing situations:
O When the engine switch is turned off.
O If only the Active TRC system is turned
off, the Active TRC will turn on when
vehicle speed increases.
If both the Active TRC and VSC systems
are turned off, automatic re-enabling will
not occur when vehicle speed increases.
Q 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.
Q If the brake system overheats
The brake system may overheat. In this
case, a buzzer will sound, “Traction Control
Turned Off” is displayed on the multi-infor-
mation display, and Active TRC and hill-
start assist control will be temporarily inop-
erable. In this event, stop the vehicle imme-
diately in a safe place, and allow the brake
system to cool down sufficiently. (There is
no problem with continuing normal driving.)
After a short time, the display message on
the multi-information display turns off, and
you will be able to use Active TRC and hill-
start assist control.
Q Operating conditions of emergency
brake signal
When the following conditions are met, the
emergency brake signal will operate:
O The emergency flashers are off.
O Actual vehicle speed is over 55 km/h
(35 mph).
O The system judges from the vehicle
deceleration that it is a sudden braking
operation.
Q Automatic system cancelation of emer-
gency brake signal
The emergency brake signal will be can-
celed in any of the following situations:
O The emergency flashers are turned on.
O The system judges from the vehicle
deceleration that is not a sudden braking
operation.
