Driving
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 move
the shift lever 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 unexpectedly,
possibly leading to an acci-
dent.
When the parking
brake is in auto-
matic mode, release the parking
brake after shifting the shift lever to
P. ( P.217)
 If the vehicle is parked without
setting the parking brake,
confirm 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.

WARNING
■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
Do not touch the rear view mirror
surfaces when the outside rear
view mirror defoggers are on.
■When the windshield wiper
de-icer is operating
Do not touch the glass at lower
part of the windshield or to the
side of the fron t pillars when the
windshield wiper de-icer is 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 conditioning
system, such as the evaporator, is
to be replaced, it must be
replaced with a new one.

■When the outside temperature
exceeds 75°F (24°C) and the air
conditioning system is on
In order to reduce the air condition-
ing power consumption, the air con-
ditioning system may switch to
recirculated air mode automatically.
This may also reduce fuel consump-
tion.
■Fogging up of the windows
●The windows will easily fog up
when the humidity in the vehicle is
high. Turning “A/C” on will dehu-
midify the air from the outlets and
defog the windshield effectively.
●If you turn “A/C” off, the windows
may fog up more easily.
■Eco air conditioning mode
When Eco drive mode is selected
using the driving mode select
switch, eco air conditioning mode
turns on.
When a drive mode other than Eco
drive mode is sele cted, eco air con-
ditioning mode may turn off.
■Operation of the air condition-
ing system in Eco drive mode
●In Eco drive mode, the air condi-
tioning system is controlled as fol-
lows to prioritize fuel efficiency:
• Engine speed and compressor operation controlled to restrict
heating/cooling capacity
• Fan speed restri cted when auto-
matic mode is selected
●To improve air conditioning perfor-
mance, perform the following
operations:
• Adjust the fan speed
• Turn off Eco drive mode ( P.308)
• Turn off Eco air conditioning mode
●When the driving mode is set to
Eco driving mode, the air condi-
tioning eco mode will be turned on
automatically. Even in this case,
the air conditioning eco mode can
be turned off by pressing the Eco
air conditioning mode switch.
■When the outside temperature
is low
The dehumidification function may
not operate even when “A/C” is
pressed.

This information has been pre-
pared in accordance with regu-
lations issued by the National
Highway Traffic Safety Adminis-
tration of the U.S. Department of
Transportation.
It provides the purchasers
and/or prospective purchasers
of Toyota vehicles with informa-
tion on uniform tire quality grad-
ing.
Your Toyota dealer will help answer
any questions you may have as you
read this information.
■DOT quality grades
All passenger vehicle tires must
conform to Federal Safety
Requirements in addition to
these grades. Quality grades
can be found where applicable
on the tire sidewall between
tread shoulder and maximum
section width.
For example: Treadwear 200 Trac-
tion AA Temperature A
■Treadwear
The treadwear grade is a com-
parative rating based on the
wear rate of the tire when tested
under controlled conditions on a
specified government test
course.
For example, a tire graded 150 would wear one and
a half (1 - 1/2)
times as well on the government
course as a tire graded 100.
The relative performance of tires
depends upon the ac tual conditions
of their use. Performance may differ
significantly from the norm due to
variations in driving habits, service
practices and diff erences in road
characteristic s and climate.
■Traction AA, A, B, C
The traction grades, from high-
est to lowest, are AA, A, B and
C, and they represent the tire’s
ability to stop on wet pavement
as measured under controlled
conditions on specified govern-
ment test surfaces of asphalt
and concrete.
A tire marked C may have poor
traction performance.
Warning: The traction grade
assigned to this tire is based on
braking (straight ahead) traction
tests and does not include corner-
ing (turning) traction.
■Temperature A, B, C
The temperature grades are A
(the highest), B, and C, repre-
senting the tire’s resistance to
the generation of heat and its
ability to dissipate heat when
tested under controlled condi-
tions on a specified indoor labo-
ratory test wheel.
Sustained high temperature can
cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure.
