Interior features
on the rear seats.
The following S-FLOW modes are
available:
Automatic S-FLOW mode
When a rear passenger is determined
to be in the vehicle ( P.259), S-
FLOW mode will be automatically dis-
abled.
The indicator will illuminate on the air con-
ditioning control screen when S-FLOW
mode is enabled.
To enable/disable S-FLOW mode and
enter manual S-FLOW mode, select the S-
FLOW mode switch.
Manual S-FLOW mode
When the S-FLOW mode switch is
selected, S-FLOW mode will be manu-
ally enabled/ disabled.
The indicator will illuminate on the air con-
ditioning control screen when S-FLOW
mode is enabled.
In this mode, the system does not
determine whether a passenger is in
the rear seats, so S-FLOW mode can-
not be automatically disabled.
To automatically disable S-FLOW
mode when opening and closing a rear
door, switch to automatic S-FLOW
mode. ( P.260)
■S-FLOW air conditioning control
Operation of S-FLOW mode changes
according to the following conditions.
However, depending on the set tem-
perature, the operation may not
change.
 Driver seat priority:
• When the system determines there is no passenger in the front passenger seat in
manual S-FLOW mode
• When the system determines there are no passengers in the front passenger
seat and rear seats in automatic S-
FLOW mode
The front passenger temperature display
turns off.
 Front seat priority:
When the system determines there are no
passengers in the rear seats
S-FLOW disabled:
When the system determines there is a
passenger in the rear seats
Refer to P.259 for details of how the sys-
tem determines whether there are passen-
gers.
■Passenger presence determination in S-
FLOW mode
The system determines that there is a pas-
senger in any of the following situations.
If a passenger is judged to be in the vehicle,
the system will retain the judgment for a
certain amount of time after the power
switch is turned off.
Front passenger seat
• When the front passenger’s door is opened and closed
• When a passenger is sitting on the front
passenger seat
• When the front passenger side seat belt is fastened
• When the front passenger seat set tem- perature is changed
After only the front pa ssenger side door is
opened and closed, when the vehicle is
driven at 12 mph (20 km/h) or more, the
system determines that there is no passen-
ger in the front passenger seat.
Rear seats
When a rear door is opened and closed

Maintenance and care
Remove dirt and dust using a vac-
uum cleaner. Wipe dirty surfaces
with a cloth dampened with luke-
warm water.
 If dirt cannot be removed, wipe it off
with a soft cloth dampened with
neutral detergent diluted to approx-
imately 1%.
Wring out any excess water from
the cloth and thoroughly wipe off
remaining traces of detergent and
water.
■Shampooing the carpets
There are several commercial foaming-type
cleaners available. Use a sponge or brush
to apply the foam. Rub in overlapping cir-
cles. Do not use water. Wipe dirty surfaces
and let them dry. Excellent results are
obtained by keeping the carpet as dry as
possible.
■Handling the seat belts
Clean with mild soap and lukewarm water
using a cloth or spon ge. Also check the
belts periodically for excessive wear, fraying
or cuts.
■When cleaning the carpeted portions of
the glove box, console box, etc.
If a strong adhesive tape is used, there is a
possibility that the surface of the carpet
could be damaged.

suddenly, become hot, or become elec-
trically energized. To avoid death or seri-
ous injury, observe the following
precautions.
■When working on the engine com-
partment
●Make sure that the “IGNITION ON”
on the multi-information display and
the “READY” indicator are both off.
●Keep hands, clothi ng and tools away
from the moving fan and engine drive
belt.
●Be careful not to touch the engine,
power control unit, radiator, exhaust
manifold, etc. right after driving as they
may be hot. Oil and other fluids may
also be hot.
●Do not leave anything that may burn
easily, such as paper and rags, in the
engine compartment.
●Do not smoke, cause sparks or expose
an open flame to fuel. Fuel fumes are
flammable.

Maintenance and care
■Tire types
●Summer 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-covered
roads or icy roads, the use of snow tires is
recommended. When installing snow
tires, be sure to replace all four tires.
●All 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, however, 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.
●Snow tires
For driving on snow-covered roads or icy
roads, we recommend using 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.242)
■If the tread on snow tires wears down
below 0.16 in. (4 mm)
The effectiveness of the tires as snow tires is
lost.
WARNING
■When 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 resulting in death or
serious injury.
●Do not mix tires of different makes,
models or tread patterns.
Also, do not mix tires of remarkably
different treadwear.
●Do not use tire sizes other than those
recommended by Lexus.
●Do not mix differently constructed
tires (radial, bias-belted or bias-ply
tires).
●Do not tow if your vehicle has a com-
pact spare tire installed.
●Do not mix summer, all season and
snow tires.
●Do 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
■Driving on rough roads
Take particular care 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.
■Low profile tires (18-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:
