Calibrating the compass (circling calibration)
To rectify the compass, stop the vehicle and push and hold the
COMPº switch until Cº appears on the display.
There is also a case that Cº appears on the display in case of
the drastic change of the magnetic field.
Drive the vehicle slowly (at 8 km/h [5
mph] or lower) in a circle
until the direction is displayed. If there is not enough space to
drive in a circle, drive around the block until the direction is
displayed.
After driving in 1 to 3 circles in the above method, calibration
is complete with the direction shown on the display.

STEERING WHEEL AND MIRRORS
233
Perform
circling calibration just after you have purchased
your Lexus. And then always perform circling calibration
after the battery has been removed, replaced or
disconnected.
 Do not perform circling calibration of the compass in a place
where the earth's magnetic field is subject to interference by
artificial magnetic fields (underground parking, under a steel
tower, between buildings, roof parking, near a crossing,
near a large vehicle, etc.).
 During calibration, do not operate electric systems (moon
roof, power windows, etc.) as they may interfere with the
calibration.
CAUTION
When doing the circling calibration, be sure to secure
a wide space, and watch out for people and vehicles
in the neighborhood. Do not violate any local traffic
rules while performing circling calibration.
 Do not adjust the display while the vehicle is moving.
Be sure to adjust the display only when the vehicle is
stopped.
VANITY MIRRORS
To use the vanity mirrors, swing the sun visor down and
slide the cover.
The vanity light comes on when you slide the cover.

(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 If you cannot shift automatic transmission
selector leverº on page 513.
(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 2nd STRTº switch. In
the second start mode, the 2nd STRTº indicator light comes
on. To cancel the second start mode, push the 2nd STRTº
switch once again.
FOUR-WHEEL DRIVE SYSTEM
(a) Four-wheel drive control
Use the four-wheel drive control lever and center
differential lock button to select the following transfer and
center differential modes.
The Hº and Lº 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 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 VSC OFFº indicator lights come on
because the function that controls engine performance
interferes with the process of freeing your wheels.

STARTING AND DRIVING
402
NOTICE
As soon as the center differential lock switch is turnedon, the VSC OFFº indicator light comes on. After thewheels are out of the ditch or off the slippery or bumpysurface, turn the center differential lock switch off.Make sure the cen ter differential lock indicator light and
vehicle stability control system off indicator light turn off.
Hº (high speed position, center differential unlocked):
Lever at Hº, 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.
Hº (high speed position, center differential locked): Lever
at Hº, 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 differential unlock
mode.
Nº (neutral position): Lever at Nº
No power is delivered to the wheels. The vehicle must be
stopped. Lº (low speed position, center differential unlocked):
Lever at Lº, 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 Lº
(low position, center differential locked) mode.
Lº (low speed position, center differential locked):
Lever
at Lº, center differential lock button pushed in
Use this for maximum power and traction. Use this for hard
pulling in sit uations the vehicle cannot negotiate even in the Lº
(low speed position, center differential unlocked) mode. Also,
using this mode when driving down steep of f-road inclines will
help contribute to increased vehicle stability.

STARTING AND DRIVING
403
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 controlº on page 409. If 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 procedureº for further instructions.
Advice for driving on slippery roads in Lº (low speed
position) mode
If you shift the four-wheel drive control lever to Lº, the
automatic transmission lever to 2º 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 Lº 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 3000 rpm (normally
engine speed is under 3000 rpm when the wheels get unstuck).
 The four-wheel drive control lever in the Lº position and the
automatic transmission lever in the Lº position or the
automatic transmission lever in the Dº or 2º with the
transmission downshifting to the first gear.
 The four-wheel drive control lever in the Lº position and the
automatic transmission lever in the Rº position
(As for the automatic transmission lever positions, see
Automatic transmissionº on page 393.)
