Driving■ABS (Anti-lock Brake Sys-
tem)
Helps to prevent wheel lock 
when the brakes are applied 
suddenly, or if the brakes are 
applied while driving on a slip-
pery road surface
■Brake assist
Generates an increased level of 
braking force after the brake 
pedal is depressed when the 
system detects a panic stop sit-
uation
■VSC (Vehicle Stability Con-
trol)
Helps the driver to control skid-
ding when swerving suddenly or 
turning on slippery road sur-
faces.
■Enhanced VSC (Enhanced 
Vehicle Stability Control)
Provides cooperative control of 
the ABS, TRAC, VSC and EPS.
Helps to maintain directional 
stability when swerving on slip-
pery road surfaces by con-
trolling steering performance.
■Trailer Sway Control
Helps the driver to control trailer 
sway by selectively applying 
brake pressure for individual 
wheels and reducing driving 
torque when trailer sway is 
detected.
■Secondary Collision Brake
When the airbag sensor detects 
a collision, the brakes and brake 
lights are automatically con-
trolled to reduce the vehicle 
speed and that helps reduce the 
possibility of further damage 
due to a secondary collision.
■TRAC (Traction Control)
Helps to maintain drive power 
and prevent the drive wheels 
from spinning when starting the 
vehicle or accelerating on slip-
pery roads
■Active Cornering Assist 
(ACA)
Helps to prevent the vehicle 
from drifting to the outer side by 
performing inner wheel brake 
control when attempting to 
accelerate during cornering
Driving assist systems
To keep driving safety and 
performance, the following 
systems operate automati-
cally in response to various 
driving situations. Be 
aware, however, that these 
systems are supplementary 
and should not be relied 
upon too heavily when oper-
ating the vehicle.

hill-start assist control systems
●A sound may be heard from the 
engine compartment when the 
brake pedal is depressed repeat-
edly, when the engine is started or 
just after the vehicle begins to 
move. This sound does not indi-
cate that a mal function has 
occurred in any of these systems.
●Any of the following conditions

■The ABS does not operate 
effectively when
●The limits of tire gripping perfor-
mance have been exceeded 
(such as excessively 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 dis-
tance. Always maintain a safe dis-
tance from the vehicle in front of 
you, especially in  the following sit-
uations:
●When driving on d irt, gravel or 
snow-covered roads
●When driving with tire chains
●When driving over bumps in the 
road
●When driving over roads with 
potholes or uneven surfaces
■TRAC/VSC may not operate 
effectively 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 con-
ditions where st ability and power 
may be lost.
■Active Cornering Assist does 
not operate effectively when
●Do not rely solely upon Active 
Cornering Assist. Active Corner-
ing Assist may not operate 
effectively when accelerating 
down slopes or driving on slip-
pery road surfaces.
●When Active Corn ering Assist 
frequently operates, Active Cor-
nering Assist may temporarily 
stop operating to ensure proper 
operation of the brakes, TRAC, 
VSC.
■Hill-start assist control does 
not operate effectively when
●Do not overly rely on hill-start 
assist control. Hill-start assist 
control may not o perate effec-
tively on steep inclines and 
roads covered with ice.
●Unlike the parking brake, hill-
start assist control is not 
intended to hold the vehicle sta-
tionary for an extended period 
of time. Do not attempt to use 
hill-start assist  control to hold 
the vehicle on an incline, as 
doing so may lead to an acci-
dent.
■When the TRAC/VSC/Trailer 
Sway Control is activated
The slip indicator  light flashes. 
Always drive carefully. Reckless 
driving may cause an accident. 
Exercise particula r care when the 
indicator light flashes.
■When the TRAC/VSC/Trailer 
Sway Control systems are 
turned off
Be especially careful and drive at 
a speed appropriate to the road 
conditions. As these are the sys-
tems to help ensure vehicle stabil-
ity and driving force, do not turn 
the TRAC/VSC/Trailer Sway Con-
trol systems off unless necessary.
Trailer Sway Control is part of the 
VSC system and will not operate 
if VSC is turned off or experiences 
a malfunction.
