Driving
■ EPS operation sound
When the steering wheel is operated, a
motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
■
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 engine 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
■
Secondary Collision Brake operating
conditions
The system operates when the SRS airbag
sensor detects a collision while the vehicle
is in motion. However, the system does not
operate in any of the following situations.
●
The vehicle speed is below 6 mph (10
km/h)
●
Components are damaged
■ Secondary Collision Brake automatic
cancellation
The system is automatically canceled in any
of the following situations.
● The vehicle speed drops below approxi-
mately 6 mph (10 km/h)
● A certain amount of time elapses during
operation
● The accelerator pedal is depressed a
large amount
■ 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
maintain 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
● When driving over roads with pot-
holes or uneven surfaces
■ TRAC/VSC may not operate effec-
tively when
Directional control and power may not
be achievable while driving on slippery
road surfaces, even if the TRAC/VSC
system is operating.
Drive the vehicle carefully in conditions
where stability and power may be lost.
