STARTING AND DRIVING
411
(g) If you cannot shift the selector lever
If you cannot shift the selector lever even though the brake
pedal is depressed, use the shift lock override button. For
instructions, see ªIf you cannot shift automatic transmission
selector leverº on page 524.
(h) Driving in second start mode
In the second start mode, the transmission system shifts up
from second gear. Use this mode when starting your vehicle
in sand, mud, ice or snow.
To set the second start mode, push the ª2nd STRTº switch. In
the second start mode, the ª2nd STRTº indicator light comes
on. To cancel the second start mode, push the ª2nd STRTº
switch once again.
FOUR±WHEEL DRIVE SYSTEM
(a) Four±wheel drive control
Use the four±wheel drive control lever and center
differential lock switch to select the following transfer and
center differential modes.
The ªHº and ªLº position of the four±wheel drive control leve\
r
provides either lock or unlock mode of the center differential
depending on the center differential lock switch position.
Use the center differential lock system if your wheels get stuck
in a ditch, or when you are driving on a slippery or bumpy
surface. When the center differential is locked, the vehicle
stability control system is automatically turned off and the
center dif ferential lock and ªVSC OFFº indicator lights come on
because the function that controls engine performance
interferes with the process of freeing your wheels.

Replacing tires and wheels
When replacing the wheels, be sure to install air pressure
sensors on the wheels.
There are 3 ways to set up the air pressure sensors:
(a) Remove the sensor from the old wheel and install it to the
new wheel.
(b) Keep the same wheel with air pressure sensor and replace
only the tire.
(c) Use a new wheel and sensor.
You have to register an ID code for a new sensor. Up to 2 sets
of codes can be registered. As one ID for the originally installed
sensor is registered at ªMAINº of the selector switch, use the
ª2ndº position to register an ID for the new sensor.
You do not need to re±register the ID code for any other
replacements. For the use of the originally installed tires, put
the selector switch at ªMAINº and for the use of tires set
purchased later, put the switch at ª2ndº. For the sensor
selector switch, see page 455.CAUTION
 Have the tires, wheels or sensors replaced and ID
codes registered by a Lexus dealer. If you need
sensors, purchase from a Lexus dealer.
 The use of non±genuine wheels will cause the air
pressure sensors to transmit the electronic code in
different manner, resulting in the failure of the
system.

Selector switch

1Main position22nd position
The selector switch is located in the lower part of the
driver's side instrument panel.
The ID code is given in the sensor. To activate the air
pressure warning system, it is necessary to register the ID
code of the sensor on the selector switch in the vehicle.2 sets of ID codes can be registered. The code of the tires
originally installed on the vehicle is registered on the switch at
ªMAINº. Have a new tires set with new air pressure sensors
registered at ª2ndº by Lexus dealer.
ID codes should be registered by Lexus dealer. Once
registered,
change the setting position each time you purchase
tires and wheels. Re±registration is not required.
When purchasing new tires, consult your Lexus dealer.
CAUTION
When the tires whose ID code is registered at ªMAINº
are used, the system does not work properly with the
selector switch set at ª2ndº. If the tires whose ID code
is registered at ª2ndº are stored nearby, the system will
detect their tire pressure (and vice versa).
