Maintenance and care ■
Initialization procedure●
Make sure to perform the initialization
procedure after adjusting the tire inflation
pressure.
Also, make sure the tires are cold before
performing the initialization procedure or
adjusting the tire inflation pressure.●
If the engine switch is turned off during
initialization, it is not necessary to restart
the initialization pr ocedure from the
beginning as it will begin automatically
when the engine switch is turned back to
IGNITION ON mode.●
If initialization has accidentally been
started when it is not necessary, adjust
the tire inflation pres sure to the specified
level when the tires are cold and then
perform the initia lization procedure
again.●
While the position of each tire is being
determined and the inflation pressures
are not being displayed on the
multi-information display, if the inflation
pressure of a tire drops, the tire pressure
warning light will come on.■
If the tire pressure warning system is not
initialized properly●
In the following situations, initialization
may take longer than usual to be com-
pleted or may not be possible. (Usually,
the vehicle will need to be driven for
approximately 10 to 30 minutes to com-
plete initialization.) If initialization is not
complete after drivin g approximately 30
minutes, continue driving for a while.
• If the vehicle is driven on an unpaved
road, it may take longer to complete ini-
tialization.
• If the vehicle is backed up while perform-
ing initialization, data collected during ini-
tialization will be cleared and it will take
longer than normal to complete.
• If the vehicle is driven in heavy traffic or
another situation where other vehicles
are driven close by, it may take time for
the system to recognize the tire pressure
warning valve and tran smitters of your
vehicle over those of other vehicles.
If initialization is no t complete after driving
for approximately 1 hour, park the vehicle in a safe place for approximately 20 minutes
and then drive the vehicle again. ●
In the following situations, initialization
will not be started or was not completed
properly and the system will not operate
properly. Perform the initialization proce-
dure 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 after performing ini-
tialization, the tire pressure warning light
blinks for approximately 1 minute and
then illuminates. ●
If initialization canno t be completed after
performing the above procedure, con-
tact 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 necessary
to register the ID codes.
The ID codes can be registered on
of the multi-information display.
1 Park the vehicle in a safe place, turn
the engine switch off, wait 20 min-
utes or more, and then start the
engine. WARNING■
When initializing the tire pressure
warning system
Do not initialize the tire pressure warning
system without first adjusting the tire
inflation pressure to the specified level.
Otherwise, 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 in flation pressure is
actually normal.

approximately 10 to 30 minutes.Registration is complete when the tire
pressure warning light turns off and the
inflation pressure of each tire is displayed
on the multi-information display.
Registration may take longer than normal
to complete if the vehicle speed cannot be
maintained at approximately 25 mph (40
km/h) or more. If registration cannot be
completed after driving for 1 hour or more, perform the registrati on procedure again
from the beginning. (  P.390)
After registering the ID codes, make sure

When trouble arises 7-2.Steps to take in an emergency
If your vehicle needs to be
towed If towing is ne cessary, we recom-
mend having your vehicle towed by
your Lexus dealer or commercial
towing service, using a wheel-lift
type truck or flatbed truck.
Use a safety chain system for all
towing, and abide by all state/pro-
vincial and local laws. WARNING
Observe the following precautions.
Failure to do so may result in death or
serious injury. ■
When towing the vehicle 
2WD models
Be sure to transport the vehicle with all
four wheels raised off the ground. If the
vehicle is towed with the tires contacting
the ground, the driv etrain and related
parts may be damaged or an accident
may occur due to a change in direction
of the vehicle. 
AWD models
Be sure to transport the vehicle with all
four wheels raised off the ground. If the
vehicle is towed with the tires contacting
the ground, the driv etrain or related
parts may be damaged, the vehicle may
fly off the truck.
■
While towing ●
When towing using cables or chains,
avoid sudden starts, etc. which place
excessive stress on the towing eyelets,
cables or chains. The towing eyelets,
cables or chains may become dam-
aged, broken debris may hit people,
and cause serious damage.
●
Make sure to disable all functions of
the vehicle height control of the elec-
tronically modulated air suspension.
Otherwise, the vehicle height may
change and part of your body may be
caught under the vehicle, possibly
causing injury. (  P.293)
●
Do not turn the engine switch off.
This may lead to an accident as the
rear wheels will be locked by the park-
ing lock.
Also, there is a possibility that the
steering wheel is locked and cannot be
operated.
