WARNING
■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 stability and power 
may be lost.
■Active Cornering Assist does 
not operate effectively when
●Do not overly rely on Active 
Cornering Assist. Active Corner-
ing Assist may  not operate 
effectively when accelerating 
down slopes or driving on slip-
pery road surfaces.
●When Active Cornering Assist 
frequently operates, Active Cor-
nering Assist may temporarily 
stop operating to ensure proper 
operation of the  brakes, TRAC 
and 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 operate 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 particular 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/Tra iler 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.
■Dynamic Torque Vectoring 
AWD system (if equipped)
The cornering performance of the 
newly developed AWD system 
has been improved. However, do 
not overly rely on the system and 
drive with caution.
■Replacing tires
Make sure that all tires are of the 
specified size, brand, tread pat-
tern and total load capacity. In 
addition, make sure that the tires 
are inflated to the recommended 
tire inflation p ressure level.
The ABS, TRAC, Trailer Sway 
Control and VSC systems will not 
function correctly if different tires 
are installed on the vehicle.
Contact your Toyota dealer for 
further information when replacing 
tires or wheels.
■Handling of tires and the sus-
pension
Using tires with any kind of prob-
lem or modifying the suspension 
will affect the driving assist sys-
tems, and may cause a system to 
malfunction.
