Vehicle stability management
(VSM) (if equipped)
This system provides further enhance‐ments to vehicle stability and steering
responses when a vehicle is driving on a
slippery road or a vehicle detected changes in coefficient of friction be‐
tween right wheels and left wheels
when braking.
VSM operation
When the VSM is in operation, • ESC (Electronic Stability Control) ()
light will blink.
• The steering wheel may be control‐ led.
When the vehicle stability management is operating properly, you can feel a
slight pulsation in the vehicle. This is
only the effect of brake control and in‐ dicates nothing unusual.

(Continued)
•The VSM is designed to function
above approximately 10 km/h
(6 mph) when a vehicle is braking
on a split-mu road. The split-mu
road is made of surfaces which
have different friction forces.
WARNING
•The Vehicle Stability Managementsystem is not a substitute for safedriving practices but a supplemen‐tary function only. It is the respon‐sibility of the driver to alwayscheck the speed and the distanceto the vehicle ahead. Always holdthe steering wheel firmly whiledriving.
•Your vehicle is designed to activateaccording to the driver’s intention,even with the VSM installed. Al‐ways follow all the normal precau‐tions for driving at safe speed forthe conditions – including driving ininclement weather and on a slip‐pery road.

(Continued)
•Driving with varying tire or wheelsizes may cause the VSM systemto malfunction. When replacingtires, make sure they are thesame size as your original tires.
Hill-start assist control (HAC) (if
equipped)
A vehicle has the tendency to slip back
on a steep hill when it starts to go af‐ ter stopping. The Hill-start Assist Con‐
trol (HAC) prevents the vehicle from
slipping back by operating the brakes automatically for about 1~2 seconds.
The brakes are released when the ac‐
celerator pedal is depressed or after about 1~2 seconds.
WARNING
The HAC is activated only for about1~2 seconds, so when the vehicle isstarting off always depress the ac‐celerator pedal.
