STARTING AND DRIVING
410
When towing a trailer, in order to maintain efficient engine
braking and electrical charging performance, do not use
overdrive.
CAUTION
Always keep your foot on the brake pedal while stopped
with the engine running. This prevents the vehicle from
creeping.
NOTICE
Always use the brake pedal or parking brake to hold the
vehicle on an upgrade. Do not attempt to hold the vehicle using the accelerator pedal, as this can causethe transmission to overheat.

(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.

STARTING AND DRIVING
412
NOTICE
As soon as the center differential lock switch is turnedon, the ªVSC 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.
ªHº (high speed position, center differential unlocked):
Lever at ªHº, center differential lock switch 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.
ªHº (high speed position, center differential locked): Lever
at ªHº, center differential lock switch pushed in
Use this for greater traction when you experience a loss of
power, such as wheel slipping, in the center differential unlock
mode.
ªNº (neutral position): Lever at ªNº
No power is delivered to the wheels. The vehicle must be
stopped. ªLº (low speed position, center differential unlocked):
Lever at ªLº, center differential lock switch 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 ªLº
(low position, center differential locked) mode.
ªLº (low speed position, center differential locked):
Lever
at ªLº, center differential lock switch pushed in
Use this for maximum power and traction. Use this for hard
pulling in sit uations the vehicle cannot negotiate even in the ªLº
(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 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 ªCruise controlº on page 419. 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.
See ª(b) Shifting procedureº for further instructions.
(b) Shifting procedure
To shift between unlock and lock modes in ªHº, push the
center differential lock switch.
To shift between unlock and lock modes in ªLº,
push the
center differential lock switch.
To shift between ªHº and ªLº, stop the vehicle, put the

REAR VIEW MONITOR SYSTEM
The rear view monitor system assists the driver by
displaying an image of the rear of the vehicle while
backing up. The displayed image on the screen is a
horizontally reversed mirror image of the inside rear view
mirror.
To display the rear view image on the screen, place the
selector lever in the ªRº position when the ignition switch
is in the ªONº position.
If you move the selector lever out of the ªRº position, the screen
returns to the previous screen. Operating another function of
the navigation system will display another screen.
The rear view monitor system is a supplemental device
intended to assist back up. When backing up, be sure to check
behind and all around the vehicle visually.
CAUTION
 Never depend on the rear view monitor system
entirely when backing up. Always make sure your
intended path is clear.
Use caution just as you would when backing up any
vehicle.
 Never back up while looking only at the screen. The
image on the screen is different from actual
conditions. Depicted distances between objects and
flat surfaces will differ from actual distances. If you
back up w hile looking only at the screen, you may hit
a vehicle, a person or an object. When backing up, be
sure to check behind and all around the vehicle
visually and with mirrors before proceeding.
 Do not use the system when the back door is not
completely closed.
 If the back of the vehicle is hit, the position and
mounting angle of the camera may change. Be sure
to have the camera's position and mounting angle
checked at your Lexus dealer.
 If the temperature changes rapidly, such as when hot
water is poured on the vehicle in cold weather, the
system may not operate normally.

If the camera lens becomes dirty, it cannot transmit
a clear image. If water droplets, snow, or mud adhere
to the lens, rinse with water and wipe with a soft cloth.
If the lens is extremely dirty, wash it with a mild
cleanser and rinse.
 The displayed image may become darker and moving
images may be slightly distorted when the system is
cold. When backing up, be sure to check behind and
all around the vehicle visually and with mirror before
proceeding.AREA DISPLAYED ON SCREEN

Corners of bumper
The area covered by the camera is limited. Objects
which are close to either corner of the bumper or under
the bumper cannot be seen on the screen.
 The area displayed on the screen may vary according
to vehicle orientation or road conditions.
If the above screen appears on the display, the back door is
open. W hen backing up the vehicle, make sure the back door
is securely closed.

STARTING AND DRIVING
418THE REAR VIEW MONITOR SYSTEM CAMERA
The rear view monitor system camera is located on the back
door as shown in the illustration. The camera uses a special
lens. The distance of the image that appears on the screen
differs from the actual distance.
In the following cases, it may become difficult to
see the images
on the screen, even when the system is functioning.
 In the dark (for example, at night)
 When the temperature near the lens is extremely high or low
 When water droplets are adhering to the camera, or when
humidity is high (for example, when it rains)
 When foreign matter (for example, snow or mud) adheres
to the camera lens
 When the sun or the beam of headlights is shining directly
into the camera lens
Check surroundings for safety.
If a bright light (for example, sunlight reflected off the vehicle
body) is picked up by the camera, the smear effect* peculiar to
the camera may occur.
*: Smear effect Ð A phenomenon that occurs when a bright
light (for example, sunlight reflected off the vehicle body) is
picked up by the camera; when transmitted by the camera, the
light source appears to have a vertical streak above and below
it.

CRUISE CONTROL
The cruise control allows you to cruise the vehicle at a
desired speed over about 40 km/h (25 mph) with your foot
off the accelerator pedal.
Your cruising speed can be maintained although a slight speed
change may occur when driving up or down a gradient, within
the limits of engine performance. On steeper hills, a greater
speed change will occur so it is better to drive without the cruise
control.
CAUTION
 To help maintain maximum control of your vehicle,
do not use the cruise control when driving in heavy
or varying traffic, or on slippery (rainy, icy or
snow±covered) or winding roads.
 Avoid vehicle speed increases when driving
downhill. If the vehicle speed is too fast in relation to
the cruise control set speed, cancel the cruise
control then downshift the transmission to use
engine braking to slow down.
Turning the system on
To operate the cruise control, push the ªON±OFFº button. This
turns the system on. The indicator light in the instrument
cluster shows that you can now set your desired cruising
speed. Another push on the switch will turn the system
completely off.
When the ignition key is turned off, the ªON±OFFº button is also
automatically turned off. To use the cruise control again, push
the ªON±OFFº button again to turn it on.
CAUTION
To avoid accidental cruise control engagement, keep
the ªON±OFFº button off when not using the cruise
control.
