1944-5. Using the driving support systems
COROLLA_U• When driving through steam or
smoke
• When the surrounding area is dim,
such as at dawn or dusk, or while
at night or in a tunnel, making a
detectable object appear to be
nearly the same color as its sur-
roundings
• When driving in a place where the
surrounding brightness changes
suddenly, such as at the entrance
or exit of a tunnel
• After the engine has started the vehicle has not been driven for a
certain amount of time
• While making a left/right turn and for a few seconds after making a
left/right turn
• While driving on a curve and for a few seconds after driving on a
curve
• If your vehicle is skidding
• If the front of the vehicle is raised or lowered
• If the wheels are misaligned
• If a wiper blade is blocking the front camera
• The vehicle is being driven at extremely high speeds
• When driving on a hill
• If the radar sensor or front camera is misaligned
●In some situations such as the fol-
lowing, sufficient braking force
may not be obtained, preventing
the system from performing prop-
erly:
• If the braking functions cannot operate to their full extent, such as
when the brake parts are
extremely cold, extremely hot, or
wet
• If the vehicle is not properly main- tained (brakes or tires are exces- sively worn, improper tire inflation
pressure, etc.)
• When the vehicle is being driven
on a gravel road or other slippery
surface
■If VSC is disabled
●If VSC is disabled ( P.252), the
pre-collision brake assist and
pre-collision braking functions are
also disabled.
●The PCS warning light will turn on
and “VSC Turned OFF Pre-Colli-
sion Brake System Unavailable”
will be displayed on the
multi-information display.

COROLLA_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 vehicle ahead of you stops, yo ur vehicle will also stop (vehicle is
stopped by system control). After the vehicle ahead starts off, pressing the
“+RES” switch or depressing the acce lerator pedal (start-off operation) will
resume follow-up cruising. If the start-of f operation is not performed, system
control continues to keep your vehicle stopped.

■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.
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

Driving
■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.
■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.
■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 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.
Press again to turn the system
back on.

WARNING
●When driving with tire chains
●When driving over bumps in the
road
●When driving over roads with
potholes or uneven surfaces
■TRAC/VSC may not operate
effectively when
Directional control and power may
not be achievable while driving on
slippery road surfaces, even if the
TRAC/VSC system is operating.
Drive the vehicle carefully in con-
ditions where stability and power
may be lost.
■Active Cornering Assist does
not operate effectively when
●Do not overly rely on Active
Cornering Assist. Active Corner-
ing Assist may not operate
effectively when accelerating
down slopes or driving on slip-
pery road surfaces.
●When Active Cornering Assist
frequently operates, Active Cor-
nering Assist may temporarily
stop operating to ensure proper
operation of the brakes, TRAC
and VSC.
■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.
■When the TRAC/VSC is acti-
vated
The slip indicato r light flashes.
Always drive carefully. Reckless
driving may cause an accident.
Exercise particular care when the
indicator light flashes.
■When the TRAC/VSC systems
are turned off
Be especially careful and drive at
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 systems off
unless necessary.
■Replacing tires
Make sure that all tires are of the
specified size, brand, tread pat-
tern and total load capacity. In
addition, make sure that the tires
are inflated to the recommended
tire inflation pressure level.
The ABS, TRAC and VSC sys-
tems will not function correctly if
different tires are installed on the
vehicle.
Contact your Toyota dealer for fur-
ther information when replacing
tires or wheels.
■Handling of tires and the sus-
pension
Using tires with any kind of prob-
lem or modifying the suspension
will affect the driving assist sys-
tems, and may cause a system to
malfunction.
■Secondary Collision Brake
Do not rely solely upon the Sec-
ondary Collision Brake. This sys-
tem is designed to help reduce
the possibility of further damage
due to a secondary collision, how-
ever, that effect changes accord-
ing to various conditions. Overly
relying on the system may result
in death or serious injury.

2564-6. Driving tips
COROLLA_U
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 shift the
shift lever to P (continuously variable transmission), or 1 or
R (manual transmission)
without setting 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.
 Vehicles with a continuously
variable transmission: If the
vehicle is parked without set-
ting the parking brake, con-
firm that the shift lever cannot
be moved out of P
*.
*: The shift lever will be locked if it is
attempted to be sh ifted 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
dealer immediately.
Use the correct tire chain size
when mounting the tire chains.
Chain size is regulated for each
tire size.
