is judged to be in a rear seat,
S-FLOW mode will be automati-
cally disabled.
When the S-FLOW mode is on, the
indicator illuminates on the
S-FLOW mode switch.
To enable/disable S-FLOW mode
and enter manual S-FLOW mode,
press the S-FLOW mode switch.
Manual S-FLOW mode
When the S-FLOW mode switch
is pressed, S-FLOW mode will
be manually enabled/ disabled.
When the S-FLOW mode is on, the
indicator illuminates on the
S-FLOW mode switch.
Operation in S-FLOW mode dif-
fers according to the following
conditions:
 Priority is given to the driver’s
seat only when:
Automatic S-FLOW mode
When no passengers are judged to
be in the front pa ssenger seat or
rear seats.
Manual S-FLOW mode
When no passenger is judged to be
in the front passenger seat.
 Priority is given to the front
seats when:
Manual S-FLOW mode is selected
or no passengers are judged to be
in the rear seats when in automatic
S-FLOW mode.
S-FLOW mode will be dis-
abled when:
A passenger is judged to be in a
rear seat when in automatic
S-FLOW mode.
Depending on the set tempera-
ture, operation in S-FLOW
mode may not change as
described above.
■How the system judges if a pas-
senger is in the vehicle when in
S-FLOW mode
In S-FLOW mode , the system
judges if a passenger is in the vehi-
cle as follows:
• Front passenger seat:
A passenger is judged to be in the
front passenger seat when the sys-
tem detects an object on the front
passenger seat, fastening of the
front passenger seat belt or the
opening and closing of the front pas-
senger door. (However, when only
opening and closing of the front pas-
senger door is detected, the system
will judge that a passenger is not in
the front passenger seat after the
vehicle speed reaches approxi-
mately 12 mph [2 0 km/h] or more.)
• Rear seats (automatic S-FLOW mode only):
A passenger is judged to be in a
rear seat when the system detects
the opening and cl osing of a rear
door.
If a passenger is judged to be in the
vehicle, the system will retain the
judgement for a ce rtain amount of
time after the power switch is turned
off.
■Operation of automatic S-FLOW
mode
When the system is operating in
automatic S-FLOW mode, if a rear
door is opened and then closed,
S-FLOW mode will be disabled. To
enable S-FLOW mode, press the
S-FLOW mode switch. (In this case,
the system will ope rate in manual

COROLLA HV_U
Remove dirt and dust using a
vacuum cleaner. Wipe dirty
surfaces with a cloth damp-
ened with lukewarm water.
 If dirt cannot be removed,
wipe it off with a soft cloth
dampened with neutral deter-
gent diluted to approximately
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 foam-
ing-type cleaners available. Use a
sponge or brush to apply the foam.
Rub in overlapping circles. 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 sponge. Also
check the belts periodically for
excessive wear, fraying or cuts.

Maintenance and care
■Checking the tire valves
When replacing the tires, check the
tire valves for deformation, cracks,
and other damage.
Rotate the tires in the order
shown.
Front
To equalize tire w ear and extend
tire life, Toyota recommends that
tire rotation is carried out at the
same interval as tire inspection.
Vehicles with a tire pressure warn-
ing system: Do not fa il to initialize
the tire pressure warning system
after tire rotation.
Your vehicle is equipped with a
tire pressure warning system
that uses tire pressure warning
valves and transmitters to detect

■When inspecting or replacing
tires
Observe the following precautions
to prevent accidents.
Failure to do so may cause dam-
age to parts of the drive train as
well as dangerous handling char-
acteristics, which may lead to an
accident resulting in death or seri-
ous injury.
●Do not mix tires of different
makes, models or tread pat-
terns.
Also, do not mix tires of remark-
ably different treadwear.
●Do not use tire si zes other than
those recommended by Toyota.
●Do not mix differently con-
structed tires (radial, bias-belted
or bias-ply tires).
●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 previ-
ously.
NOTICE
■If tire inflation pressure of
each tire becomes low while
driving
Do not continue driving, or your
tires and/or wheels may be
ruined.
■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 cush ioning ability of
the tires. In addition, driving on
rough roads may cause damage
to the tires themselves, as well as
the vehicle’s wheels and body.
