STARTING AND DRIVING
266
(g) Driving in “2nd STRT” (second start)mode
31X012c
In the “2nd STRT” (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 “2nd STRT” mode, push the “2nd” switch. In the “2nd
STRT” mode, the “2nd STRT” indicator light comes on. To
cancel the “2nd STRT” mode, push the “2nd” switch again.
The “PWR” mode is automatically cancelled when you push
the “2nd” switch.
(h) If you cannot shift the selector lever
If you cannot shift the selector lever from “P” position even
though the brake pedal is depressed, use the shift lock
override button. For instruct ions, see “If you cannot shift
automatic transmission selector lever” on page 357.
FOURWHEEL DRIVE SYSTEM
(a) Fourwheel drive control
31X013e
Use the fourwheel drive control lever and center
differential lock button to select the fo llowing transfer and
center differential modes.
The “H” and “L” position of the four−wheel drive control lever
provides either lock or unlock mode of the center differential
depending on the center differential lock button position.
Use the center dif ferential 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 “VSC OFF” indicator lights come on
because the function that controls engine performance
interferes with the process of freeing your wheels.

STARTING AND DRIVING
267
NOTICE
As soon as the center differential lock switch is turned
on, the “VSC OFF” indicator light comes on. After the
wheels are out of the ditch or off the slippery or bumpy
surface, turn the center differential lock switch off.
Make sure the center differential lock indicator light and
vehicle stability control system off indicator light turn
off.
“H” (high speed position, center differential unlocked):
Lever at “H”, center differential lock button left out
Use this for normal driving on all types of roads, from dry
hard−surfaced roads to wet, icy or snow −covered roads. This
position gives greater economy, quietest ride, least wear and
better vehicle control.
“H” (high speed position, center differential locked):
Lever at “H”, center differential lock button pushed in
Use this for greater traction when you experience a loss of
power, such as wheel slipping, in the center dif ferential unlock
mode.
“N” (neutral position): Lever at “N”
No power is delivered to the wheels. The vehicle must be
stopped. “L” (low speed position, center differential unlocked):
Lever at “L”, center differential lock button left out
Use this for maximum power and traction. Use this for climbing
or descending steep hills, off
−road driving, and hard pulling in
sand or mud.
In this mode, the braking feeling that occurs when the wheels
are negotiating a sharp corner is further reduced than in the “L”
(low position, center differential locked) mode.
“L” (low speed position, center differential locked): Lever
at “L”, center differential lock button pushed in
Use this for maximum power and traction. Use this for hard
pulling in situations the vehicle cannot negotiate even in the “L”
(low speed position, center differential unlocked) mode. Also,
using this mode when driving down steep off −road inclines will
help contribute to increased vehicle stability.
The indicator light tells when the differential lock is engaged.
Note that the differential is not still locked as long as the
indicator light remains off.
When the operation is not completed, the indicator blinks. If
the indicator light does not go off when you push out the center
differential lock switch, drive straight ahead while accelerating
or decelerating, or drive in reverse.
The center differential lock system operation is not completed
within 5 seconds while the cruise control system is set, cancel
the cruise control system. To cancel the cruise control system,
see “Cruise control” on page 275.

STARTING AND DRIVING
268If the indicator light does not go off when you push out the
center differential lock button, drive straight ahead while
accelerating or decelerating, or drive in reverse.
See “(b) Shifting procedure” for further instructions.
Advice for driving on slippery roads in “L” (low speed
position) mode
If you shift the four
−wheel drive control lever to “L”, the
automatic transmission lever to “2” when you drive in steep
off −road areas, the output of the brake can be controlled
effectively by the active traction control system, which assists
the driver to control the driving power of 4 wheels.
Use the “L” position of the automatic transmission lever for
maximum power and traction when your wheels get stuck or
when you drive down a steep incline. In the following cases,
the out put of the brake can be controlled by the active traction
control system if the engine speed is under 3,000 rpm
(normally engine speed is under 3,000 rpm when the wheels
get unstuck).
 The four− wheel drive control lever in the “L” position and the
automatic transmission lever in the “L” position or the
automatic transmission lever in the “D”, “4”, “3” or “2” \
with
the transmission downshifting to the first gear
 The four− wheel drive control lever in the “L” position and the
automatic transmission lever in the “R” position
(As for the automatic transmission lever positions, see
“Automatic transmission” on page 259.)
(b) Shifting procedure
To shift between unlock and lock modes in “H”, push the
center differential lock button.
To shift between unlock and lock modes in “L”, push the
center differential lock button.
To shift between “H” and “L”, stop the vehicle, put the
transmission into “N” and move the four −wheel drive control
lever.
CAUTION
Never move the fourwheel drive control lever if wheels
are slipping. Stop the slipping or spinning before
shifting.
NOTICE
For normal driving on dry and hard surface roads,
unlock the center dif ferential. To prevent damage to the
center differential lock system, do not push the center
differential lock button when the vehicle is cornering or
when its wheels are spinning freely of f the ground. If the
indicator light does not go off when unlocking the
center differential, drive straight ahead while
accelerating or decelerating, or drive in reverse.

The vehicle stability control system is activated when the
vehicle speed is about more than 15 km/h (9 mph).
You may hear a sound in the engine compartment for a few
seconds when the engine is started or just after the vehicle
begins to move. This means that the vehicle stability control
is in the self−
check mode and does not indicate a malfunction.
31X529
Pushing the center differential lock button automatically turns
the vehicle stability control system off. At this time, the “VSC
OFF” indicator comes on with the center differential lock
indicator light. (For details, see “Four −wheel drive system” on
page 266.)
31x505
 Vehicle stability control system failure warning
These lights warn when there is a problem somewhere in the
vehicle stability control system or active traction control
system.
If the “VSC/TRAC” warning light and “VSC OFF” indicator light
come on, have your vehicle checked by your Lexus dealer as
soon as possible. However, there is no problem even if the
“VSC/TRAC” warning light comes on when the brake actuator
temperature becomes high. (For details, see “Active traction
control system” on page 288.)
When the “ABS” warning light comes on, the vehicle stability
control system is not operating.
The lights will come on when the ignition key is turned to “ON”,
and will go off after a few seconds.
The lights may stay on for 60 seconds after the ignition key is
turned to the “ON” position. It is normal if they go off after a few
seconds.

STARTING AND DRIVING
292Depressing
the brake pedal repeatedly may turn on the lights.
It is normal if they go off after a few seconds.
When the “VSC/TRAC” warning light and “VSC OFF” indicator
light come on, the vehicle stability control system is not
operating, but there is no problem if you continue to drive.
In the following cases, contact your Lexus dealer:
 The “VSC/TRAC” warning light, “VSC OFF” indicator light
and slip indicator light do not come on after the ignition is
turned to on.
 The “VSC/TRAC” warning light and “VSC OFF” indicator
light remain on after the ignition is turned to on.
 The “VSC OFF” indicator light comes on while driving
without pushing the center differential lock switch.
CAUTION
Active traction control system, vehicle stability
control system and antilock brake system are
electronic systems designed to help the driver
maintain control under adverse conditions. They are
not a substitute for safe driving practices. Factors
including speed, road conditions and driver steering
input can all affect whether active traction control
system, vehicle stability control system and
