you, especially in the following sit-  
uations:  
Reduced effectiveness of the  
EPS system  
The effectiveness of the EPS sys-  
tem is reduced to prevent the sys-  
tem from overheating when there is  
frequent steering input over an  
extended period of time. The steer-  
ing 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.

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 systems off  
unless necessary.  
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.  
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 pressure level.  
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.  
The ABS, TRAC and VSC sys-  
tems will not function correctly if  
different tires are installed on the  
vehicle.  
Contact your Toyota dealer for fur-  
ther information when replacing  
tires or wheels.  
When Active Cornering Assist  
frequently operates, Active Cor-  
nering Assist may temporarily  
stop operating to ensure proper  
operation of the brakes, TRAC  
and VSC.

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.  
Secondary Collision Brake  
Do not rely solely upon the Sec-  
ondary Collision Brake. This sys-  
tem is designed to help reduce  
the possibility of further damage  
due to a secondary collision, how-  
ever, that effect changes accord-  
ing to various conditions. Overly  
relying on the system may result  
in death or serious injury.  
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.

vated  
The slip indicator light flashes.  
Always drive carefully. Reckless  
driving may cause an accident.  
Exercise particular care when the  
indicator light flashes.
