following functions: a Park-
ing Support Brake function
(static objects to the front
and rear) that detects static
objects such as walls, a
Parking Support Brake
function (rear-crossing
vehicles)
* that detects vehi-
cles approaching from the
rear while backing up, a
Parking Support Brake
function (rear pedestrians)

WARNING
■When the TRAC/ABS/VSC is
activated
The slip indicator light flashes.
Always drive care fully. 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
further 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 driv ing 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.

4305-6. Driving tips
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, outside rear
view mirrors, windows, vehi-
cle’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.

Turn automatic mode of the
parking brake off.
Otherwise, the parking brake
may freeze and not be able to
be released automatically.
Also, avoid using the following as
the parking brake may operate
automatically, even if automatic
mode is off.
• Brake hold system
Park the vehicle and shift the
shift position 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 dangerous
because it may cause the
vehicle to move unexpect-
edly, possibly leading to an
accident.
 When the parking brake is in
automatic mode, release the
parking brake after shifting
the shift position to P.
( P.264)
NOTICE
■Repairing or replacing snow
tires
Request repairs or replacement of
snow tires from your Toyota
dealer 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.

ting.
3 To stop the operation, press
the “OFF” switch.
If the fan speed setting or air
flow modes are operated, the
automatic mode indicator goes
off. However, automatic mode
for functions other than that
operated is maintained.
■Using automatic mode
Fan speed is adjusted automati-
cally according to the temperature
setting and the ambient conditions.
Therefore, the fan may stop for a
while until warm or cool air is ready
to flow immediately after the auto-
matic mode switch is pressed.
Cool air may blow around the upper
body even when the heater is on
due to sunlight.
■Windshield fog detection func-
tion
When automatic mode is set, the
humidity sensor detects fog on the
windshield and controls the air con-
ditioning system to prevent fog.
WARNING
■Cautions for using “My Room
Mode”
Do not leave children, people who
need assistance, or pets inside
the vehicle. The system may turn
off automatically and the interior
temperature may become high or
low, resulting in heat stroke, dehy-
dration or hypothermia. Failure to
do so may result in death or seri-
ous injury.
■To prevent the windshield
from fogging up
Do not use the windshield defog-
ger switch during cool air opera-
tion in extremely humid weather.
The difference between the tem-
perature of the outside air and
that of the windshield can cause
the outer surface of the wind-
shield to fog up, blocking your
vision.
■When the outside rear view
mirror defoggers are operat-
ing (if equipped)
Do not touch the rear view mirror
surfaces when the outside rear
view mirror defoggers are on.
NOTICE
■To prevent 12-volt battery dis-
charge
Do not leave the air conditioning
system on longer than necessary
when the hybrid system is off.
■When repairing/replacing
parts of the air conditioning
system
Have repair/replacement per-
formed by your Toyota dealer.
When a part of the air condition-
ing system, such as the evapora-
tor, is to be replaced, it must be
replaced with a new one.
