■Trail Mode
●Trail Mode controls the vehicle so
that it can use the maximum
amount of drive force when driving
on rough 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, depend-
ing on the driving conditions, the
load on related parts increases
and the system may not function
correctly.
In this case, “Traction Control
Turned OFF” will be shown on the
multi-information display but the
Trail Mode
Trail Mode is designed to
control the spinning of the
drive wheels by integratedly
controlling AWD, brake and
drive force control sys-
tems. Use the Trail Mode
when driving bumpy roads,
etc.

Make sure to observe the follow-
ing precautions. Failure to
observe these precautions may
result in an unexpected accident.
●Trail mode is intended for use
when driving on rough roads.
●Check that the Trail Mode indi-
cator is illumina ted before driv-
ing.
●Trail Mode is not intended to
expand the limits of the vehicle.

Toyota dealer immediately.
■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
NOTICE
■In order to ensure that Trail
Mode operates properly
Do not continuously use the Trail
Mode for a long period of time.
Depending on the driving condi-
tions, the load on related parts
increases and the system may not
operate properly.
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.
Summary of the driving
assist systems

3765-5. Using the driving support systems
■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 maintai n 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
(ACA)
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
starting on an uphill
■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 controls the drive
system such as to front-wheel
drive or AWD (all wheel drive)
according to various running
conditions including normal driv-
ing, during cornering, on a
uphill, when starting off, during
acceleration, on a slippery roads
due to snow or rain, thus con-
tributing to stable operability and
driving stability.
■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/Trail
Mode/Trailer Sway Control sys-
tems are operating
The slip indicator light will flash
while the TRAC/VSC/ABS/Trail
Mode/Trailer Sway Control systems
are operating.
