system detects a panic stop sit-
uation
■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
■Hill-start assist control
Helps to reduce the backward
movement of the vehicle when
starting on an uphill
■AVS (Adaptive Variable
Suspension System) (if
equipped)
The damping force of the shock
absorbers are independently
controlled for the 4 wheels
according to factors including
the road surface conditions and
driving operation, contributing
toward enhancing smooth driv- ing comfort and superior stabil-
ity, and helping to maintain
vehicle posture.
In addition, the damping force
can be changed by selecting the
drive mode with the driving
mode select (
P.358), and driv-
ing comfort can be ensured
during off-road driving by setting
the front-wheel drive control
switch to “4L”.( P.361)
■EPS (Electric Power Steer-
ing)
Employs an electric motor to
reduce the amount of effort
needed to turn the steering
wheel
■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.

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

ditions where stability and power
may be lost.
■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.

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.

8 For confirmation, repeat
steps 6 and 7 until desired
“gain” setting is reached (just
below point of trailer wheel
lock-up).
■When setting the “gain”
Wheel lock-up occurs when the
trailer wheel squeals or tire smoke
occurs. Trailer wheels may not lock-
up while driving heavily loaded
trailer. During this case, adjust the
Trailer “gain” to the highest allow-
able setting for the towing condition.
■When disconnecting and recon-
necting 12-volt battery termi-
nals
The “gain” setting data will be reset.
■Trailer Sway Control Function
Helps suppress trailer sway at an
early stage by using the trailer brake
control system to operate the trailer
brakes.
■If the Trailer brake warning light
comes on
Indicates a malfunction in the Trailer
brake control system or Trailer con-
nector circuit.
Have the vehicle inspected by your
Toyota dealer immediately.
WARNING
■Trailer brake type setting
It is the responsibility of the driver
to make sure the trailer brakes
are functioning normally and
adjusted appropriately. Failure to
check and maintain trailer brakes
may result in loss of vehicle con-
trol, crash, or serious injury.
Trailer brake control system will
work with most electric and elec-
tric-overhydraulic trailer braking
systems up to 3 axles (24A output
to trailer brakes). Please be sure
to test compatibility with the sys-
tem at low speeds and in a safe
area. If a warning message
appears in the multi-information
display ( P.511), have the vehi-
cle inspected by your Toyota
dealer immediately. Some elec-
tric-over-hydraulic trailer brakes
will take some minimum output to
activate. Trailer brake control sys-
tem will not work with trailer
hydraulic surge brakes.

When using Eco drive mode, the
torque corresponding to the
accelerator pedal depression
amount can be generated more
smoothly than it is in normal
conditions. In addition, the oper-
ation of the air conditioning sys-
tem (heating/cooling) will be
minimized, improving the fuel
economy. ( P.358)
The Eco-friendly driving is pos-
sible by keeping the indicate of
Hybrid System Indicator within
Eco area. ( P.97)
Shift the shift lever to D when
stopped at a traffic light, or driv-
ing in heavy traffic etc. Shift the
shift lever to P when parking.
When using the N, there is no
positive effect on fuel consump-
tion. When using the air condi-
tioning system, etc., the hybrid
battery (traction battery) power
is consumed. 
Drive your vehicle smoothly.
Avoid abrupt acceleration and
deceleration. Gradual accel-
eration and deceleration will
make more effective use of
the electric motor (traction
motor) without having to use
gasoline engine power.
 Avoid repeated acceleration.
Repeated acceleration con-
sumes hybrid battery (trac-
tion battery) power, resulting
in poor fuel consumption. Bat-
tery power can be restored by
driving with the accelerator
pedal slightly released.
Make sure to operate the brakes
gently and in a timely manner. A
greater amount of electrical
energy can be regenerated
when slowing down.
Repeated acceleration and
deceleration, as well as long
waits at traffic lights, will lead to
bad fuel economy. Check traffic
reports before leaving and avoid
delays as much as possible.
When driving in a traffic jam,
gently release the brake pedal
to allow the vehicle to move for-
ward slightly while avoiding

Driving
Perform the following according
to the driving conditions:
 Do not try to forcibly open a
window or move a wiper that
is frozen. Pour warm water
over the frozen area to melt
the ice. Wipe away the water
immediately to prevent it from
freezing.
 To ensure proper operation of
the climate control system
fan, remove any snow that
has accumulated on the air
inlet vents in front of the wind-
shield.
 Check for and remove any
excess ice or snow that may
have accumulated on the
exterior lights, vehicle’s roof,
chassis, around the tires or on
the brakes.
 Remove any snow or mud
from the bottom of your shoes
before getting in the vehicle. Accelerate the vehicle slowly,
keep a safe distance between
you and the vehicle ahead, and
drive at a reduced speed suit-
able to road conditions.

Park the vehicle and move
the shift lever to P without set-
ting the parking brake. The
parking brake may freeze up,
preventing it from being
released. If the vehicle is
parked without setting the
parking brake, make sure to
block the wheels.
Failure to do so may be dan-
gerous because it may cause
the vehicle to move unexpect-
edly, possibly leading to an
accident.
When the parking brake is in auto-
matic mode, release the parking
brake after shifting the shift lever to
P. ( P.206)
 If the vehicle is parked without
setting the parking brake,
confirm that the shift lever
cannot be moved out of P
*.
*: The shift lever will be locked if it is
attempted to be shifted from P to
any other position without
depressing the brake pedal. If the
shift lever can be shifted from P,
there may be a problem with the
shift lock system. Have the vehi-
cle inspected by your Toyota
NOTICE
■Repairing or replacing snow
tires
Request repairs or replacement of
snow tires from Toyota dealers or
legitimate tire retailers.
This is because the removal and
attachment of snow tires affects
the operation of the tire pressure
warning valves and transmitters.
