3106-1. Maintenance and care
Remove dirt using a water-damp-
ened soft cloth or synthetic chamois.
 Wipe the surface with a dry soft
cloth to remove any remaining
moisture.
■Cleaning the areas with satin-finish
metal accents
The metal areas use a layer of real metal for
the surface. It is necessary to clean them
regularly. If dirty area s are left uncleaned for
long periods of time, they may be difficult to
clean.
 Remove dirt and dust using a vac-
uum cleaner.
 Wipe off any excess dirt and dust
with a soft cloth dampened with
diluted detergent.
Use a diluted water solution of approxi-
mately 5% neutral wool detergent.
Wring out any excess water from
the cloth and thoroughly wipe off all
remaining traces of detergent.
 Wipe the surface with a dry soft
cloth to remove any remaining
moisture. Allow the leather to dry in
a shaded and ventilated area.
■Caring for leather areas
Lexus recommends cleani ng the interior of
the vehicle at least twice a year to maintain
the quality of the vehicle’s interior.
NOTICE
■Preventing damage to leather sur-
faces
Observe the following precautions to
avoid damage to and deterioration of
leather surfaces:
●Remove any dust or dirt from leather
surfaces immediately.
●Do not expose the vehicle to direct
sunlight for extended periods of time.
Park the vehicle in the shade, espe-
cially during summer.
●Do not place items made of vinyl, plas-
tic, or containing wax on the uphol-
stery, as they may stick to the leather
surface if the vehicle interior heats up
significantly.
■Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio system
may be damaged if water comes into
contact with electrical components such
as the audio system above or under the
floor of the vehicle. Water may also
cause the body to rust.
■When cleaning the inside of the wind-
shield
Do not allow glass cleaner to contact the
lens. Also, do not touch the lens.
(  P.172)
■Cleaning the inside of the rear win-
dow
●Do not use glass cleaner to clean the
rear window, as this may cause dam-
age to the rear window defogger
heater wires or antenna. Use a cloth
dampened with lukewarm water to
gently wipe the window clean. Wipe
the window in strokes running parallel
to the heater wires or antenna.
●Be careful not to scratch or damage
the heater wires or antenna.

●Tire inflation pressure changes with tem-
perature. The displayed values may also
be different from the values measured
using a tire pressure gauge.
■Situations in which the tire pressure
warning system may not operate prop-
erly
●In the following cases, the tire pressure
warning system may not operate prop-
erly.
• If non-genuine Lexus wheels are used.
• A tire has been replaced with a tire that is
not an OE (Original Equipment) tire.
• A tire has been replaced with a tire that is
not of the specified size.
• Tire chains etc. are equipped.
• An auxiliary-supported run-flat tire is
equipped.
• If a window tint that affects the radio wave
signals is installed.
• If there is a lot of snow or ice on the vehi- cle, particularly around the wheels or
wheel housings.
• If the tire inflation pressure is extremely higher than the specified level.
• If wheel without tire pressure warning
valves and transmitters are used.
• If the ID code on the tire pressure warn- ing valves and transmitters is not regis-
tered in the tire pressure warning
computer.
●Performance may be af fected in the fol-
lowing situations.
• Near a TV tower, electric power plant, gas station, radio stat ion, large display,
airport or other fac ility that generates
strong radio waves or electrical noise
• When carrying a portable radio, cellular
phone, cordless phone or other wireless
communication device
If tire position information is not correctly
displayed due to the radio wave conditions,
the display may be corrected by driving and
changing the radio wave conditions.
●When the vehicle is parked, the time
taken for the warning to start or go off
could be extended.
●When tire inflation pr essure declines rap-
idly for example when a tire has burst, the
warning may not function.
■Warning 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 trouble arises
press it briefly 3 times or more in
succession.

Stop the vehicle in a safe place by
the road. 
Remove the seat belt first.
 If the door can be opened, open the
door and exit the vehicle.
 If the door can not be opened, open
the window using the power window
switch and exit the vehicle through
the window.
 If the window can not be opened
using the power window switch,
remain calm, wait until the water
level inside the vehicle rises to the
point that the water pressure inside
of the vehicle equals the water pres-
sure outside of the vehicle, and then
open the door and exit the vehicle.
WARNING
■If the hybrid system has to be turned
off while driving
Power assist for the steering wheel will
be lost, making the steering wheel
heavier to turn. Decelerate as much as
possible before turning off the hybrid sys-
tem.
If the vehicle is trapped in
r
ising water
In the event the vehicle is sub-
merged in water, remain calm and
perform the following.
WARNING
■Using an emergency hammer*1 for
emergency escape
The rear side windows and rear window
of this vehicle can be shattered by an
emergency hammer
*1 used for emer-
gency escape, however, since the wind-
shield and front side windows
*2 are
laminated glass they can not be shattered
by an emergency hammer
*1.
*1: Contact your Lexus dealer or after-
market accessory manufacturer for
further information about an emer-
gency hammer.
*2: Vehicles with laminated glass

3587-1. Essential information
■How to distinguish laminated glass
When looking from the cross-sectional
view point, laminated glass is two sheets of
glass pasted together.
Laminated glass
Tempered glass
WARNING
■Escaping the vehicle from the window
There are cases where escaping the
vehicle from the window is not possible
due to seating position, passenger body
type, etc.
When using an emergency hammer,
consider your seat location and the size
of the window opening to ensure that the
opening is accessible and large enough
to escape.

4138-1. Specifications

Vehicle specifications
■Traction AA, A, B, C
The traction grades, from highest to
lowest, are AA, A, B and C, and they
represent the tire’s ability to stop on
wet pavement as measured under con-
trolled 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
cornering (turning) traction.
■Temperature A, B, C
The temperature grades are A (the
highest), B, and C, representing 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 laboratory
test wheel.
Sustained high temperature can cause the
material of the tire to degenerate and
reduce tire life, and excessive temperature
can lead to sudd
en tire failure.
Grade C corresponds to a level of perfor-
mance which all passenger car tires must
meet under the Fede ral Motor Vehicle
Safety Standard No. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel
than the minimum required by law.
Warning: The temperature grades of a tire
assume that it is properly inflated and not
overloaded.
Excessive speed, unde rinflation, or exces-
sive loading, either separately or in combi-
nation, can cause heat buildup and
possible tire failure.
