BSM (Blind Spot Moni-
tor)
The Blind Spot Monitor is a
system that uses rear side
radar sensors installed on
the inner side of the rear
bumper on the left and right
side to assist the driver in
confirming safety when
changing lanes.
WA R N I N G
■Cautions regarding the use of
the system
The driver is solely responsible for
safe driving. Always drive safely,
taking care to observe your sur-
roundings.
The Blind Spot Monitor is a sup-
plementary function which alerts
the driver that a vehicle is in a
blind spot of the outside rear view
mirrors or is approaching rapidly
from behind into a blind spot. Do
not overly rely on the Blind Spot
Monitor. As the function cannot
judge if it is safe to change lanes,
over reliance could lead to an
accident resulting in death or seri-
ous injury.
As the system may not function
correctly under certain condi-
tions, the driver’s own visual con-
firmation of safety is necessary.

■Trail Mode
●Trail Mode is intended for use
when driving on bumpy roads. Do
not turn the switch on in other situ-
ations.
●Trail Mode controls the vehicle so
that it can use the maximum
amount of drive force when driving
on bumpy roads. As a result, fuel
efficiency may diminish when
compared to driving with Trail
Mode off.
●If Trail Mode is continuously used
for a long period of time, the load
on related parts increases and the
system may be un able to operate
effectively.
■When Trail Mode is canceled
In the following situations, Trail
Mode is automatically canceled
even if it is turned on.
●When the driving mode is
changed (P.316)
●When the power switch is turned
off
■During Trail Mode operation
The following types of situations
may occur, but they are not malfunc-
tions.
●Vibrations may be felt throughout
the vehicle or steering wheel
●Operating noise may be heard
from the engine compartment
■When an inspection at your
Toyota dealer is necessary
In the following si tuations, the sys- tem may be malf
unctioning. Have
the vehicle inspected by your Toyota
dealer immediately.
●When the slip indicator illuminates
while Trail Mode is on
●When the Trail Mode indicator
does not illuminat e even though
the Trail Mode switch is pressed

Driving■ECB (Electronically Con-
trolled Brake System)
The electronically controlled
system generates braking force
corresponding to the brake
operation
■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.
■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

Helps to prevent the vehicle
from drifting to the outer side by
performing inner wheel brake
control when attempting to
accelerate while turning
■Hill-start assist control
Helps to reduce the backward
movement of the vehicle when
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.

■EPS (Electric Power Steer-
ing)
Employs an electric motor to
reduce the amount of effort
needed to turn the steering
wheel
■E-Four
Electronic On-Demand AWD
system. Automatically switches
from front-wheel drive to
all-wheel drive (AWD) according
to the driving conditions, helping
to ensure reliable handling and
stability. Examples of conditions
where the system will switch to
AWD are when cornering, going
uphill, starting off or accelerat-
ing, and when the road surface
is slippery due to snow, rain, etc.
■VDIM (Vehicle Dynamics
Integrated Management)
Provides integrated control of
the ABS, brake assist, TRAC,
VSC, hill-start assist control and
EPS systems
Helps to maintain vehicle stabil-
ity when swerving on slippery
road surfaces by controlling the
brakes, hybrid system output
and steering assist.
■The Secondary Collision
Brake
When the SRS airbag sensor
detects a collision and the sys-
tem operates, the brakes and
brake lights are automatically
controlled to reduce the vehicle speed and help reduce the pos-
sibility of further damage due to
a secondary collision.
■When the
TRAC/VSC/ABS/Trailer Sway
Control systems
are operating
The slip indicator light will flash
while the TRAC/VSC/ABS/Trailer
Sway Control systems are operat-
ing.
■Disabling the TRAC system
If the vehicle gets stuck in mud, dirt
or snow, the TRAC system may
reduce power from the hybrid sys-
tem to the wheels. Pressing the
switch to turn th e system off may
make it easier for you to rock the
vehicle in order to free it.

■Active Cornering Assist opera-
tion sounds and vibrations
When the Active Cornering Assist is
operated, operation sounds and
vibrations may b e generated from
the brake system, but this is not a
malfunction.
■EPS operation sound
When the steering wheel is oper-
ated, a motor sou nd (whirring
sound) may be heard. This does not
indicate a malfunction.
■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 hybrid
system off. The E PS system should
return to normal within 10 minutes.
■Automatic reactivation of
