2084-5. Using the driving support systems
COROLLA H/B_UWhen the turn signal lever is operated and your vehicle moves to an over-
taking lane while driving at 50 mph (
80 km/h) or more, the vehicle will accel-
erate to help to overtake a passing vehicle.
The system’s identification of what is an overtaking lane may be determined
solely based on the location of the steering wheel in the vehicle (left side
driver position versus right side driver position.) If the vehicle is driven to a
region where the overtaking lane is on a different side from where the vehi-
cle is normally driven, the vehicle may accelerate when the turn signal lever
is operated in the opposite direction to the overtaking lane (e.g., if the driver
normally operates the vehicle in a region where the overtaking lane is to the
right but then drives to a region where the overtaking lane is to the left, the
vehicle may accelerate when the ri ght turn signal is activated).
Example of acceleration
When there are no longer any preceding vehicles driving slower
than the set speed
The system accelerates until the set speed is reached. The system then
returns to constant speed cruising.
1 Press the cruise control main
switch to activate the cruise
control.
Dynamic radar cruise control indi-
cator will come on and a message
will be displayed on the multi-infor-
mation display. Press the switch
again to deactivate the cruise con-
trol.
If the cruise control main switch is
pressed and held for 1.5 seconds
or more, the system turns on in
constant speed control mode. (

2 Accelerate or decelerate,
with accelerator pedal opera-
tion, to the desired vehicle
speed (at or above approxi-
mately 20 mph [30 km/h])
and press the “-SET” switch
to set the speed.
Cruise control “SET” indicator will
come on.

COROLLA H/B_U
This mode employs a radar to detect the presence of vehicles up to
approximately 328 ft. (100 m) ahead, determines the current vehi-
cle-to-vehicle following distance, and operates to maintain a suitable
following distance from the vehicle ahead. The desired vehi-
cle-to-vehicle distance can also be set by operating the vehi-
cle-to-vehicle distance switch.
When driving on downhill slopes, the vehicle-to-vehicle distance may
become shorter.
Example of const ant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected running ahea d of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle speed is nec-
essary, the system applies the brakes (the stop lights will come on at this
time). The system will respond to ch anges 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 turn signal lever is operated and your vehicle moves to an over-
taking lane while driving at 50 mph ( 80 km/h) or more, the vehicle will accel-
erate to help to overtake a passing vehicle.
The system’s identification of what is an overtaking lane may be determined
solely based on the location of the steering wheel in the vehicle (left side

WARNING
■When using the rear view
monitor system
The rear view monitor system is a
supplemental device intended to
assist the driver when backing up.
When backing up, be sure to visu-
ally check all around the vehicle
both directly and using the mirrors
before proceeding. Observe the
following precautions to avoid an
accident that could result in death
or serious injuries.
●Never depend on the rear view
monitor system entirely when
backing up. The image and the
position of the guide lines dis-
played on the screen may differ
from the actual state. Use cau-
tion, just as you would when
backing up any vehicle.
●Be sure to back up slowly,
depressing the brake pedal to
control vehicle speed.
●The instructions given are only
guide lines. When and how
much to turn the steering wheel
will vary according to traffic con-
ditions, road surface condi-
tions, vehicle condition, etc.
when parking. It is necessary to
be fully aware of this before
using the rear view monitor sys-
tem.
●When parking, be sure to check
that the parking space will
accommodate your vehicle
before maneuvering into it.
●Do not use the rear view moni-
tor system in the following
cases:
• On icy or slick road surfaces, or in snow
• When using tire chains or emer- gency tires
• When the back door is not closed completely
• On roads that are not flat or straight, such as curves or
slopes
●In low temperatures, the screen
may darken or the image may
become faint. The image could
distort when the vehicle is mov-
ing, or you may become unable
to see the image on the screen.
Be sure to visually check all
around the vehicle both directly
and using the mirrors before
proceeding.
●If the tire sizes are changed, the
position of the fixed guide lines
displayed on the screen may
change.
●The camera uses a special lens.
The distances between objects
and pedestrians that appear in
the image displayed on the
screen will differ from the actual
distances. ( P.240)
NOTICE
■How to use the camera
●The rear view monitor system
may not operate properly in the
following cases.
• If the back of the vehicle is hit, the position and mounting angle
of the camera may change.
• As the camera has a water proof construction, do not
detach, disassemble or modify
it. This may cause incorrect
operation.

■Enhanced VSC (Enhanced
Vehicle Stability Control)
Provides cooperative control of
the ABS, TRAC, VSC and EPS.
Helps to maintain directional
stability when sw erving on slip-
pery road surfaces by con-
trolling steering performance.
■Secondary Collision Brake
When the airbag sensor detects
a collision, the brakes and stop
lights are automatically con-
trolled to reduce the vehicle
speed and that helps reduce the
possibility of further damage
due to a secondary collision.
■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.
■When the TRAC/VSC systems
are operating
The slip indicator light will flash
while the TRAC/VSC systems are
operating.
■Disabling the TRAC system
If the vehicle gets stuck in mud, dirt
or snow, the TRAC system may
reduce power from the engine to the
wheels. Pressing to turn the
system off may make it easier for
you to rock the vehicle in order to
free it.
To turn the TRAC system off, quickly
press and release .
The “Traction Control Turned OFF”
will be shown on the multi-informa-
tion display.

TRAC is temporary deactivated. If
the information continues to show,
contact your Toyota dealer.
■Operating conditions of
hill-start assist control
When the following four conditions
are met, the hill-star t assist control
will operate:
●Vehicles with a continuously vari-
able transmission: The shift lever
is in a position other than P or N
(when starting off forward/back-
ward on an upward incline).
●Vehicles with a manual transmis-
sion: The shift lever is in a position
other than R when starting off for-
ward on an upward incline, or the
shift lever is in R when starting off
backward on an upward incline.
●The vehicle is stopped
●The accelerator pedal is not
depressed
●The parking brake is not engaged
■Automatic system cancelation
of hill-start assist control
The hill-start assist control will turn
off in any of the following situations:
●Vehicles with a continuously vari-
able transmission: The shift lever
is shifted to P or N.
●Vehicles with a manual transmis-
sion: The shift leve r is shifted to R
when starting off forward on an
upward incline, or the shift lever is
shifted to other than R when start-
ing off backward on an upward
incline.
●The accelerator pedal is
depressed
●The parking brake is engaged
●2 seconds at maximum elapsed
after the brake pedal is released
■Sounds and vibrations caused
by the ABS, brake assist, VSC,
TRAC and hill-start assist con-
trol systems
●A sound may be heard from the
engine compartment when the
brake pedal is depressed repeat-
edly, when the engine is started or
just after the vehicle begins to
move. This sound does not indi-
cate that a malfunction has
occurred in any of these systems.
●Any of the following conditions
may occur when the above sys-
tems are operating. None of these
indicates that a malfunction has
occurred.
• Vibrations may be felt through the
vehicle body and steering.
• A motor sound may be heard also after the vehicle comes to a stop.
• The brake pedal may pulsate
slightly after th e ABS is activated.
• The brake pedal may move down slightly after th e ABS is activated.
■Active Cornering Assist opera-
tion sounds and vibrations
When the Active Cornering Assist is
operated, operation sounds and
vibrations may be generated from

Driving
the brake system, but this is not a
malfunction.
■EPS operation sound
When the steering wheel is oper-
ated, a motor sound (whirring
sound) may be heard. This does not
indicate a malfunction.
■Automatic reacti vation of TRAC
and VSC systems
After turning the TRAC and VSC
systems off, the systems will be
automatically re-enabled in the fol-
lowing situations:
●When the engine switch is turned
off
●If only the TRAC system is turned
off, the TRAC will turn on when
vehicle speed increases
If both the TRAC and VSC sys-
tems are turned off, automatic
re-enabling will not occur when
vehicle speed increases.
■Operating conditions of Active
Cornering Assist
The system operates when the fol-
lowing occurs.
●TRAC/VSC can operate
●The driver is at tempting to accel-
erate while turning
●The system detects that the vehi-
cle is drifting to the outer side
●The brake pedal is released
■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.
■Secondary Collision Brake
operating conditions
The vehicle speed is approximately
6 mph (10 km/h) or more and the
airbag sensor detects a collision.
(The Secondary Collision Brake will
not operate when the vehicle speed
is below approximately 6 mph [10
km/h].)
■Secondary Collision Brake
automatic cancellation
The Secondary Collision Brake is
automatically canceled in the follow-
ing situations:
●The vehicle speed drops below
approximately 6 mph (10 km/h)
●A certain amount of time elapses
during operation
●The accelerator pedal is
depressed a large amount
WARNING
■The ABS does not operate
effectively when
●The limits of tire gripping perfor-
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 dirt, gravel or
snow-covered roads
●When driving with tire chains
●When driving over bumps in the
road
