This mode employs a radar to detect the presence of vehicles up to
approximately 328 ft. (100 m) ahead, determines the current veh icle-
to-vehicle following distance, and operates to maintain a suitable fol-
lowing distance from the vehicle ahead. The desired vehicle-to- vehi-
cle distance can also be set by operating the vehicle-to-vehicl e
distance switch.
When driving on downhill slopes, t he vehicle-to-vehicle distance may
become shorter.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration crui sing and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected runni ng ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle s peed is nec-
essary, the system applies the brakes (the stop lights will come on at this
time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you st ops, your vehicle will also stop (vehicle is
stopped by system control). Afte r the vehicle ahead starts off, pressing the
“+RES” switch or depressing the accelerator pedal (start-off operation) will
resume follow-up cruising. If the start-off operation is not pe rformed, system

■The system can be operated
when
●The power switch is in ON.
●Intuitive parking assist function is
on.
●The vehicle speed is less than
about 6 mph (10 km/h).
●A shift position other than P is
selected.
■If “Parking Assist Unavailable
Clean Parking Assist Sensor” is
displayed on the multi-informa-
tion display
A sensor may be covered with water
drops, ice, snow, dirt, etc. Remove
the water drops, ice, snow, dirt, etc.,
from the sensor to return the system
to normal.
Also, due to ice forming on a sensor
at low temperatures, a warning
message may be displayed or the
sensor may not be able to detect an
object. Once the ice melts, the sys-
tem will return to normal.
If a warning message is displayed
even if the sensor i s clean, there
may be a sensor malfunction. Have
the vehicle inspected by your Toyota
dealer.
■If “Parking Assist Unavailable”
is displayed on the multi-infor-
mation display
Water may be continuously flowing
WARNING
●Do not attach a sticker or install
an electronic component, such
as a backlit license plate (espe-
cially fluorescent type), fog
lights, fender pole or wireless
antenna near a radar sensor.
●Do not subject the surrounding
area of the sensor to a strong
impact. If subjected to an
impact, have the vehicle
inspected by your Toyota
dealer. If the fr ont or rear
bumper needs to be
removed/installed or replaced,
contact your Toyota dealer.
●Do not modify, disassemble or
paint the sensors.
●Do not attach a license plate
cover.
●Keep your tires properly
inflated.
■When to disable the function
In the following situations, disable
the function as it may operate
even though there is no possibility
of a collision.
●Failing to observe the warnings
above.
●A non-genuine Toyota suspen-
sion (lowered suspension, etc.)
is installed.
■Notes when washing the vehi-
cle
Do not apply intensive bursts of
water or steam to the sensor
area.
Doing so may result in the sensor
malfunctioning.
●When using a high pressure
washer to wash the vehicle, do
not spray the sensors directly,
as doing so may cause a sensor
to malfunction.
●When using steam to clean the
vehicle, do not direct steam too
close to the sensors as doing so
may cause a sensor to malfunc-
tion.

■When the Crawl Control sys-
tem is operated continuously
●If Crawl Control is used continu-
ously for a long time, the brake
system overheats . In this case, a
buzzer will sou nd, a message
stating a malfunction will be dis-
played on the multi-information
display, and the Crawl Control
indicator will flash and then go off.
In this event, as Crawl Control will
be temporarily inoperable, stop
the vehicle immediately in a safe
place, and allow the brake system
to cool down suffi ciently until the
message goes off. (In the mean-
time, normal driving is possible.)
●If Crawl Control is used continu-
ously for a long time, the auto-
matic transmission overheats. In
this case, a buzzer will sound, the
system will be temporarily can-
celed, and a message stating a
malfunction may be displayed on
the multi-informat ion display. In
this event, stop th e vehicle in a
safe place until the message goes
off.
■Sounds and vibrations caused
by the Crawl Control system
●A sound may be heard from the
hybrid system compartment when
the hybrid system is started or just
after the vehicle begins to move.
This sound does not indicate that
a malfunction has occurred in
Crawl Control system.
●Either of the following conditions
may occur when the Crawl Control
system is operating. None of
these are indicators that a mal-
function has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after
the vehicle comes to a stop.
■When there is a malfunction in
the system
Warning lights and/or warning mes-
sages will tu rn on. (P.501, 511)

Downhill assist con-
trol system*
The downhill assist control
system helps to prevent
excessive speed on steep
downhill slopes. The sys-
tem will operate when the
vehicle is traveling under 18
mph (30 km/h) and transfer
mode is in “4H”.
WARNING
■When using downhill assist
control system
Do not rely overmuch on the
downhill assist control system.
This function does not extend the

■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.
