charging, charging may stop due to the protection function on the portable
device side. In this case, when the tem-
perature of the port able device drops
significantly, charge again. ■

■
Initializing the tire pressure warning sys-
tem
Initialize the system with the tire inflation
pressure adjusted to the specified level.
■
The initialization operation
●
Make sure to carry ou t initialization after
adjusting the tire inflation pressure.
Also, make sure the tires are cold before
carrying out initializat ion or tire inflation
pressure adjustment.
●
If you have accidenta lly turned the power
switch off during initialization, it is not necessary to press the reset switch again
as initialization will restart automatically
when the power switch has been turned
to ON mode for the next time. ●
If you accidentally press the reset switch
when initialization is not necessary, adjust
the tire inflation pressure to the specified
level when the tires are cold, and conduct
initialization again. ■
Warning performance of the tire pres-
sure warning system
The warning of the tire pressure warning
system will change in accordance with the
conditions under which it was initialized. 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 initialized. ■
When initialization of the tire pressure
warning system has failed
Initialization ca n be completed in a few min-
utes. However, in the following cases, the
settings have not been recorded and the
system will not operate properly. If repeated
attempts to record tire inflation pressure
settings are unsuccessf ul, have the vehicle
inspected by your Lexus dealer. ●
When operating the tire pressure warn-
ing reset switch, the tire pressure warning
light does not blink 3 times. ●
After carrying out the initialization proce-
dure, the tire pressure warning light
blinks for 1 minute then stays on after
driving for 20 minutes.
WARNING
■
When initializing the tire pressure
warning system
Do not initializing tire inflation pressure
without first adjusting the tire inflation
pressure to the spec ified level. Other-
wise, the tire pressu re warning light may
not come on even if the tire inflation pres-
sure is low, or it may come on when the
tire inflation pressure is actually normal.

The compact spare tire●
The compact spare tire is identified by the
label “TEMPORARY USE ONLY” on
the tire sidewall.
Use the compact spare tire temporarily,
and only in an emergency.
●
Make sure to check the tire inflation pres-
sure of the compact spare tire. ( → P.406)
■
After completing the tire change
The tire pressure warning system must be
reset. ( → P.341)
■
When using the compact spare tire
As the compact spare tire is not equipped
with a tire pressure warning valve and trans-
mitter, low inflation pressure of the spare
tire will not be indicated by the tire pressure warning system. Also, if you replace the
compact spare tire afte r the tire pressure
warning light comes on, the light remains
on. ■
When the compact spare tire is
equipped
The vehicle becomes lower when driving
with the compact spare tire compared to
when driving with standard tires. ■
If you have a flat front tire on a road cov-
ered with snow or ice
Install the compact spare tire on one of the
rear wheels of the vehicle. Perform the fol-
lowing steps and fit tire chains to the front
tires:
1 Replace a rear tire with the compact
spare tire.
2 Replace the flat front tire with the tire
removed from the rear of the vehicle.
3 Fit tire chains to the front tires.
WARNING■
When using the compact spare tire ●
Remember that the sp are tire provided
is specifically designed for use with
your vehicle. Do not use your spare
tire on another vehicle. ●
Do not use more than one spare tire
simultaneously.
●
Replace the spare tire with a standard
tire as soon as possible.
●
Avoid sudden acceleration, abrupt
steering, sudden br aking and shifting
operations that cause sudden engine
braking.

Starting the hybrid system when the 12-
volt battery is discharged
The hybrid system cannot be started by
push-starting. ■
To prevent 12-volt battery discharge●
Turn off the headlights and the audio sys-
tem while the hybrid system is off.●
Turn off any unnecessary electrical com-
ponents when the vehicle is running at a
low speed for an extended period, such
as in heavy traffic.■
Charging the 12-volt battery
The electricity stored in the 12-volt battery
will discharge gradua lly even when the
vehicle is not in use, due to natural dis-
charge and the draining effects of certain
electrical appliances. If the vehicle is left for
a long time, the 12-volt battery may dis-
charge, and the hybrid system may be
unable to start. (The 12-volt battery
recharges automatically while the hybrid
system is operating.) ■
When the 12-volt battery is removed or
discharged●
In some cases, it may not be possible to
unlock the doors using the smart access
system with push-button start when the
12-volt battery is discharged. Use the
wireless remote control or the mechani-
cal key to lock or unlock the doors.●
The hybrid system may not start on the
first attempt after the 12-volt battery has
recharged but will start normally after the
second attempt. This is not a malfunction.●
The power switch mode is memorized by
the vehicle. When the 12-volt battery is
reconnected, the system will return to the
mode it was in before the 12-volt battery
was discharged. Before disconnecting
the 12-volt battery, turn the power switch
off.
If you are unsure what mode the power
switch was in before the 12-volt battery
discharged, be especially careful when
reconnecting the 12-volt battery.
●
The power back door mu st be initialized.
( → P.110) ■
When replacing the 12-volt battery ●
Use a 12-volt battery that the case size is
same as the previous one (LN2), 20 hour
rate capacity (20HR) is equivalent
(60Ah) or greater, and performance rat-
ing (CCA) is equivalent (460A) or
greater.
• If the sizes differ, the 12-volt battery can-
not be properly secured.
• If the 20 hour rate capacity is low, even if
the time period where the vehicle is not
used is a short time, the 12-volt battery
may discharge and hybrid system may
not be able to start. ●
After exchanging, firmly attach the fol-
lowing items to the exhaust hole of the 12-
volt battery.
• Use the exhaust hose that was
attached to the 12-volt battery before
exchanging and confirm that it is firmly
connected to the hole section of the vehi-
cle.
• Use the exhaust hole plug included
with the 12-volt battery exchanged or the
one installed on the battery prior to the
exchange. (Depending on the 12-volt
battery to be exchanged, the exhaust
hole may be plugged.)
