Driving your vehicle Brake system
ESC OFF usage
When driving
僅 ESC should be turned on for daily
driving whenever possible.
僅 To turn ESC off while driving, press
the ESC OFF button while driving on a
flat road surface.
WARNING
Operating ESC
Never press the ESC OFF button while
ESC is operating (ESC indicator light
blinks).
If ESC is turned off while ESC is operat
-
ing, the vehicle may slip out of control.
NOTICE
僅When operating the vehicle on a
dynamometer, ensure that the ESC is
turned off (ESC OFF light appeared). If
the ESC is left on, it may prevent the
vehicle speed from increasing, and
result in false diagnosis.
僅 Turning the ESC off does not affect
ABS or brake system operation.
Hill-start Assist Control (HAC)
A vehicle has the tendency to roll back
on a steep hill when it starts to go after
stopping. The Hill-start Assist Control
(HAC) prevents the vehicle from rolling
back by applying the brakes automati
-
cally for about 2 seconds.
The brakes are released when the accel -
erator pedal is engaged or after about 2
seconds.
The HAC is activated only for about 2
seconds, so when the vehicle is starting
off always engaged the accelerator
pedal.
WARNING
Maintaining brake pressure on incline
HAC does not replace the need to apply
brakes while stopped on an incline.
While stopped, make sure you maintain
brake pressure sufficient to prevent your
vehicle from rolling backward and caus
-
ing an accident. Don't release the brake
pedal until you are ready to accelerate
forward.
Vehicle Stability Management
(VSM) system
The Vehicle Stability Management (VSM)
provides further enhancements to vehi
-
cle stability and steering responses
under the following condition:
僅 when driving on a slippery road or
僅 when a change in the coefficient of
friction between left and right wheels
is detected.
WARNING
Tire/wheel size
When replacing tires and wheels, make
sure they are the same size as the origi -
nal tires and wheels installed. Driving
with varying tire or wheel sizes may
diminish any supplemental safety bene -
fits of the VSM system.
VSM operation
When the VSM is operating properly,
you can feel a slight pulsation in the
vehicle and/or abnormal steering
responses (Motor Driven Power Steering
(MDPS)). This is only the effect of brake
and MDPS control and indicates nothing
unusual.
