Driving
■Active Cornering Assist opera-
tion sounds and vibrations
When the Active Cornering Assist is
operated, operation sounds and
vibrations may be generated from
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 syste
m should return
to normal within 10 minutes.
■Secondary Collision Brake
operating conditions
The system operates when the SRS
airbag sensor detects a collision
while the vehicle is in motion.
However, the system does not oper-
ate in any of the following situations.
●The vehicle speed is below 6 mph
(10 km/h)
●Components are damaged
■Secondary Collision Brake
automatic cancellation
The system is automatically can-
celed in any of the following situa-
tions.
●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

Driving
4-6.Driving tips
Use fluids that are appropriate
to the prevailing outside tem-
peratures.
• Engine oil
• Engine coolant
• Washer fluid
Have a service technician
inspect the condition of the
battery.
Have the vehicle fitted with
four snow tires or purchase a
set of tire chains for the front
tires.
Ensure that all tires are the same
size and brand, and that chains
match the size of the tires.
Winter driving tips
Carry out the necessary
preparations and inspec-
tions before driving the
vehicle in winter. Always
drive the vehicle in a man-
ner appropriate to the pre-
vailing weather conditions.
Pre-winter preparations
WARNING
■Driving with snow tires
Observe the following precautions
to reduce the risk of accidents.
Failure to do so may result in a
loss of vehicle control and cause
death or serious injury.
●Use tires of the size specified.
●Maintain the recommended
level of air pressure.
●Do not drive in excess of 75
mph (120 km/h), regardless of
the type of snow tires being
used.
●Use snow tires on all, not just
some wheels.
■Driving with tire chains
Observe the following precautions
to reduce the risk of accidents.
Failure to do so may result in the
vehicle being unable to be driven
safely, and may cause death or
serious injury.
●Do not drive in excess of the
speed limit specified for the tire
chains being used, or 30 mph
(50 km/h), whichever is lower.
●Avoid driving on bumpy road
surfaces or over potholes.
●Avoid sudden acceleration,
abrupt steering, sudden brak-
ing and shifting operations that
cause sudden engine braking.
●Slow down sufficiently before
entering a curve to ensure that
vehicle control is maintained.
●Do not use LTA (Lane Tracing
Assist) system. (if equipped)
●Do not use LDA (Lane Depar-
ture Alert with steering control)
system. (if equipped)
NOTICE
■Repairing or replacing snow
tires (vehicles with a tire pres-
sure warning system)
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.

3465-13. Phone operation (Hands-free system for cellular phones)
COROLLA_U
●This system is not guaranteed to
operate with all Bluetooth®
devices.
●If your cellular phone does not
support Bluetooth®, this system
cannot function.
●In the following conditions, the
system may not function:
• The cellular phone is turned off.
• The current position is outside the
communication area.
• The cellular phone is not con-
nected.
• The cellular phone has a low bat- tery.
●Depending on the type of Blue-
tooth® phone, some function is
not available.
●When using the hands-free sys-
tem or Bluetooth® audio and
Wi-Fi® Hotspot functions at the
same time, the following problems
may occur:
• The Bluetooth
® connection may
be cut.
• Noise may be heard on the Blue-
tooth
® audio playback.
• A noise may be heard during phone calls.
●Bluetooth® uses the 2.4 GHz fre-
quency band. If both a Wi-Fi® con-
nection and Bluetooth®
connection are being used simul-
taneously, each connection may
be affected.
●If a Bluetooth® device is attempt-
ing to connect to the vehicle while
another device is connected as a
Bluetooth
® audio device or con-
nected using the hands-free sys-
tem or Wi-Fi
® Hotspot function,
the communication speed may
decrease or malfunctions may
occur, such as image distortion or
audio skipping. If a Bluetooth
®
device is connected to the system,
the interference it may cause will
be reduced. When carrying a
device with its Bluetooth
® connec-
tion enabled, make sure to regis-
ter it to the system and connect it
or disable its Bluetooth
® function.
●When a device is connected via
Bluetooth®, the Bluetooth® icon
on the status bar will be displayed
in blue. ( P.264)
Some basics
The hands-free system
enables calls to be made
and received without having
to take your hands off the
steering wheel.
This system supports Blue-
tooth
®. Bluetooth® is a wire-
less data system that
enables cellular phones to
be used without being con-
nected by a cable or placed
in a cradle.
The operating procedure of
the phone is explained here.
When an Apple CarPlay
connection is established,
phone functions will be per-
formed by Apple CarPlay
instead of the hands-free
system.
WARNING
●While driving, do not operate a
cellular phone.
