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
windshield.
 Check for and remove any excess
ice or snow that may have accumu-
lated 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.
QTo protect the windshield wipers
 P.172
Accelerate the vehicle slowly, keep a
safe distance between you and the
vehicle ahead, and drive at a reduced
speed suitable to road conditions.
 Park the vehicle and move the shift
lever to P without setting the park-
ing 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 lead-
ing to an accident.
When the parking brake is in automatic
mode, release the parking brake after shift-
ing the shift lever to P. (
P.159)
 If the vehicle is left parked with the
brakes damp in cold temperatures,
there is a possibility of the brakes
freezing.
 If the vehicle is parked without set-
ting 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 shifted 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 Lexus dealer
immediately.
Vehicles with 17-inch tires
Use the correct tire chain size when
mounting the tire chains.
Chain size is regulated for each tire
size.

WARNING
QWhen parking the vehicle
When parking the vehicle without apply-
ing the parking brake, make sure to
chock the wheels. If you do not chock the
wheels, the vehicle may move unexpect-
edly, possibly resulting in an accident.

lations before installing chains.
QTire chain installation
Observe the following precautions when
installing and re moving chains:
OInstall and remove tire chains in a safe
location.
OInstall tire chains on the front tires. Do not
install tire chains on the rear tires.
OInstall tire chains on front tires as tightly as possible. Retighten chains after driving
1/4 - 1/2 mile (0.5 - 1.0 km).
OInstall tire chains following the instruc-
tions provided with the tire chains.
To enable the windshield wipers to be
lifted when heavy snow or icy condi-
tions are expected, change the rest
position of the windshield wipers from

tors are showing on a tire.
QWhen to replace your vehicle’s tires
OTires should be replaced if:
• The treadwear indicators are showing on
a tire.
• You have tire damage such as cuts, splits, cracks deep enough to expose the fabric,
and bulges indicating internal damage
• A tire goes flat repeatedly or cannot be properly repaired due to the size or loca-
tion of a cut or other damage
If you are not sure, consult your Lexus
dealer.
OVehicles with 17-inch tires:
The wheel angle differs from vehicles
equipped with 18-inch/19-inch tires. There-
fore, 18-inch/19-inch tires cannot be
installed, as sufficient gaps with surrounding
parts cannot be ensured.
QTire life
Any tire over 6 years old must be checked
by a qualified technician even if it has sel-
dom or never been used or damage is not
obvious.
QLow profile tires (18-inch/19-inch tires)
Generally, low profile tires will wear more
rapidly and tire grip performance will be
reduced on snowy and/or icy roads when
compared to standard tires. Be sure to use
snow tires on snowy and/or icy roads and
drive carefully at a speed appropriate for
road and weather conditions.
QMaximum load of tire
Check that the maximum load of the
replacement tire is greater than 1/2 of the
Gross Axle Weight Ratings (GAWR) of
either the front axle or the rear axle, which-
ever is greater.
For the GAWR, see the Certification Label.
For the maximum load of the tire, see the
load limit at maximum cold tire inflation
pressure mentioned on the sidewall of the
tire. ( P.412)
QTire types
OSummer tires
Summer tires are high-speed perfor-
mance tires best suited to highway driv-
ing under dry conditions. Since summer
tires do not have the same traction per-
formance as snow tires, summer tires are
inadequate for driving on snow-covered
or icy roads. For driving on snow-cov-
ered roads or icy roads, the use of snow
tires is recommended. When installing
snow tires, be sure to replace all four
tires.
OAll season tires
All season tires are designed to provide
better traction in snow and to be ade-
quate for driving in most winter condi-
tions as well as for use year-round. All
season tires, howeve r, do not have ade-
quate traction performance compared
with snow tires in heavy or loose snow.
Also, all season tires fall short in accelera-
tion and handling performance com-
pared with summer tires in highway
driving.
OSnow tires
For driving on snow-covered roads or icy
roads, we recommend us ing snow tires. If
you need snow tires, select tires of the
same size, construction and load capacity
as the originally installed tires. Since your
vehicle has radial tires as original equip-
ment, make sure your snow tires also
have radial construction. Do not install
studded tires without first checking local
regulations for possible restrictions.
Snow tires should be installed on all
wheels. ( P.260)
QIf the tread on snow tires wears down
below 0.16 in. (4 mm)
The effectiveness of the tires as snow tires is
lost.

3326-3. Do-it-yourself maintenance
Rotate the tires in the order shown.
To equalize tire wear and extend tire life,
Lexus recommends that tire rotation is car-
ried out at the same interval as tire inspec-
tion.
Do not fail to initialize the tire pressure
warning system after tire rotation.
QWhen rotating the tires
Make sure that the power switch is off. If the
tires are rotated while the power switch is in
ON mode, the tire position information will
not be updated.
If this accidentally occurs, either turn the
power switch to off and then to ON mode,
or initialize the system after checking that
the tire pressure is properly adjusted.
WARNING
QWhen inspecting or replacing tires
Observe the following precautions to
prevent accidents.
Failure to do so may cause damage to
parts of the drivetrain as well as danger-
ous handling characteristics, which may
lead to an accident re sulting in death or
serious injury.
ODo not mix tires of different makes,
models or tread patterns.
Also, do not mix tires of remarkably
different treadwear.
ODo not use tire sizes other than those
recommended by Lexus.
ODo not mix differently constructed
tires (radial, bias-belted or bias-ply
tires).
ODo not tow if your vehicle has a com-
pact spare tire installed.
ODo not mix summer, all season and
snow tires.
ODo not use tires that have been used
on another vehicle.
Do not use tires if you do not know
how they were used previously.
NOTICE
QDriving on rough roads
Take particular car e when driving on
roads with loose surfaces or potholes.
These conditions may cause losses in tire
inflation pressure, reducing the cushion-
ing ability of the tires. In addition, driving
on rough roads may cause damage to
the tires themselves, as well as the vehi-
cle’s wheels and body.
QLow profile tires (18-inch/19-inch
tires)
Low profile tires may cause greater dam-
age than usual to the tire wheel when
sustaining impact from the road surface.
Therefore, pay attention to the following:
OBe sure to use proper tire inflation
pressure. If tires are under-inflated,
they may be damaged more severely.
OAvoid potholes, uneven pavement,
curbs and other road hazards. Failure
to do so may lead to severe tire and
wheel damage.
QIf tire inflation pressure of each tire
becomes low while driving
Do not continue driving, or your tires
and/or wheels may be ruined.

3346-3. Do-it-yourself maintenance
QWarning performance of the tire pres-
sure warning system
The warning of the tire pressure warning
system will change in accordance with driv-
ing conditions. For this reason, the system
may give a warning even if the tire pressure
does not reach a low enough level, or if the
pressure is higher than the pressure that
was adjusted to when the system was initial-
ized.
When replacing tires or wheels, tire
pressure warning valves and transmit-
ters must also be installed.
When new tire pressure warning
valves and transmitters are installed,
new ID codes must be registered in the
tire pressure warning computer and
the tire pressure warning system must
be initialized. ( P.336)
QWhen replacing the tires and wheels
If the ID code of the tire pressure warning
valve and transmitter is not registered, the
tire pressure warning system will not work
properly. After driving for about 20 min-
utes, the tire pressure warning light blinks
for 1 minute and stays on to indicate a sys-
tem malfunction.
QThe tire pressure warning system
must be initialized in the following
circumstances:
 When rotating the tires.
 When the tire inflation pressure is
changed when changing traveling
speed.
 When the tire inflation pressure is
changed such as when changing tire
size. (When there are multiple spec-
ified pressures)
 After registering the ID codes.
( P.336)
When the tire pressure warning sys-
tem is initialized, the current tire infla-
tion pressure is set as the benchmark
pressure.
Installing tire pressure warning
valves and transmitters
NOTICE
QRepairing or replacing tires, wheels,
tire pressure warning valves, trans-
mitters and tire valve caps
OWhen removing or fitting the wheels,
tires or the tire pressure warning
valves and transmitters, contact your
Lexus dealer as the tire pressure warn-
ing valves and transmitters may be
damaged if not handled correctly.
OMake sure to install the tire valve caps.
If the tire valve caps are not installed,
water could enter the tire pressure
warning valves and the tire pressure
warning valves could be bound.
OWhen replacing tire valve caps, do not
use tire valve caps other than those
specified. The cap may become stuck.
QTo avoid damage to the tire pressure
warning valves and transmitters
When a tire is repaired with liquid seal-
ants, the tire pressure warning valve and
transmitter may not operate properly. If a
liquid sealant is used, contact your Lexus
dealer or other qualified service shop as
soon as possible. Make sure to replace
the tire pressure warning valve and
transmitter when replacing the tire.

Maintenance and care
QHow to initialize the tire pressure
warning system
1 Park the vehicle in a safe place and
stop the hybrid system for 20 min-
utes or more.
Initialization cannot be performed while
the vehicle is moving.
2Adjust the tire inflation pressure to
the specified cold tire inflation
pressure level.
Make sure to adjust the tire pressure to the
specified cold tire inflation pressure level.
The tire pressure warning system will oper-
ate based on this pressure level.
3Start the hybrid system ( P.148)
4 Press or of the meter con-
trol switches and select .
5 Press or of the meter con-
trol switches and select “Vehicle
Settings”, then press “OK”.
6 Press or of the meter con-
trol switches and select “TPWS”,
then press “OK”.
7 Press or of the meter con-
trol switches and select “Set Pres-
sure”. Then press and hold “OK”
until the tire pressure warning light
starts blinking.
A message is displayed on the multi-infor-
mation display. Also, “--” is displayed for
inflation pressure of each tire on the multi-
information display while the tire pressure warning system determines the position.
8
Drive at approximately 25 mph
(40 km/h) or more for approxi-
mately 10 to 30 minutes.
When initialization is complete, the infla-
tion pressure of each tire will be displayed
on the multi-information display.
Even if the vehicle is not driven at approxi-
mately 25 mph (40 km/h) or more, initial-
ization can be completed by driving for a
long time. However, if initialization does
not complete after driving for 1 hour or
more, park the vehicle in a safe place for
approximately 20 minutes and then drive
the vehicle again.
QWhen initializing
OInitialization is perfor med while driving at
a vehicle speed of approximately 25 mph
(40 km/h) or more.
OMake sure to carry out initialization after
adjusting the tire inflation pressure.
Also, make sure the tires are cold before
carrying out initializatio n or tire inflation
pressure adjustment.
OThe tire pressure warning system can be
initialized by yourself, but depending on
the driving conditions and driving envi-
ronment, initialization may take some
time to complete.
QThe initialization operation
OIf you have accidentally turned the power
switch off during initialization, it is not
necessary to manually restart the initial-
ization again, as initialization will restart
automatically the next time the power
switch is turned to ON mode.

3366-3. Do-it-yourself maintenance
OIf you accidentally perform initialization
when initialization is not necessary, adjust
the tire inflation pressure to the specified
level when the tires are cold, and conduct
initialization again.
OWhile the position of each tire is being
determined and the inflation pressures
are not being displayed on the multi-
information display, if the inflation pres-
sure of a tire drops, the tire pressure
warning light will come on.
QIf the tire pressure warning system is not
initialized properly
OIn the following situations, initialization
may take longer than usual to be com-
pleted or may not be possible. Normally,
initialization completes within approxi-
mately 30 minutes.
• Vehicle is not driven at approximately 25
mph (40 km/h) or more
• Vehicle is driven on unpaved roads
• Vehicle is driven near other vehicles and system cannot recognize tire pressure
warning valve and transmitters of your
vehicle over those of other vehicles
If initialization does not complete after driv-
ing for 1 hour or more, park the vehicle in a
safe place for approximately 20 minutes
and then drive the vehicle again.
OIf the vehicle is reversed during initializa-
tion, the data up to that point is reset, so
perform the initia lization procedure
again from the beginning.
OIn the following situations, initialization
will not be started or was not completed
properly and the system will not operate
properly. Perform the initialization pro-
cedure again.
• If, when attempting to start initialization,
the tire pressure warning light does not
blink 3 times.
• If, when the vehicle has been driven for
about 20 minutes afte r performing initial-
ization, the tire pressure warning light
blinks for approximately 1 minute and
then illuminates.
If initialization cannot be completed after
performing the above procedure, contact
your Lexus dealer.
Every tire pressure warning valve and
transmitter has a unique ID code.
When replacing a tire pressure warn-
ing valve and transmitter, it is neces-
sary to register the ID code.
When registering the ID codes, per-
form the following procedure.
1 Park the vehicle in a safe place, wait
for approximately 20 minutes, and
then start the hybrid system.

WARNING
QWhen initializing the tire pressure
warning system
Do not initialize tire inflation pressure
without first adjusting the tire inflation
pressure to the specified level. Other-
wise, the tire pressure warning light may
not come on even if the tire inflation
pressure is low, or it may come on when
the tire inflation pressure is actually nor-
mal.
