(b) Using engine braking
31X009f
To use the braking power of the engine, downshift the
transmission in the way described below:
1 Shift into the “4” position. The transmission will downshift
to fourth gear and engine braking will be enabled.
When the cruise control is being used, even if you
downshift from “D” to “4”, engine braking will not be
enabled because the cruise control is not cancelled. If
you need to decrease the vehicle speed, see page 278.
2 Shift into the “3” position. The transmission will downshift
to third gear when the vehicle speed is or becomes lower
than the speed listed below and stronger engine braking
will be enabled.
Transfer “H” 129 km/h (80 mph)
“L” 51 km/h (32 mph)
3Shift into the “2” position. The transmission will downshift
to second gear when the vehicle speed is or becomes
lower than the speed listed below and more powerful
engine braking than that of “3” position will be enabled.
Transfer “H” 88 km/h (55 mph) “L” 35 km/h (22 mph)
4Shift into the “L” position. The transmission will downshift
to first gear when the vehicle speed is or becomes lower
than the speed listed below and maximum engine braking
will be enabled.
Transfer “H” 37 km/h (23 mph) “L” 14 km/h (9 mph)
CAUTION
Be careful when downshifting on a slippery surface.
The abrupt change in engine speed could cause the
vehicle to skid or spin.

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.

If this warning light comes on, the bulb of the
nearinfrared floodlight (night view projector) has blown
out. Have the bulb replaced at your Lexus dealer.
CRUISE CONTROL
The cruise control is designed to maintain a set cruising
speed without requiring the driver to operate the
accelerator. Cruising speed can be set to any speed
above 40 km/h (25 mph).
Within the limits of the engine’s capabilities, cruising speed can
be maintained up or down grades. However, changes in
vehicle speed may occur on steeper grades.
When the cruise control is on, the driving pattern of the
automatic transmission is fixed in the normal position,
regardless of the position of the driving pattern selector switch.
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
snowcovered) 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 and off
31X604
To turn the cruise control on, press the “ON–OFF” button. The
“CRUISE” indicator light in the instrument cluster will come on
to indicate that the cruise control is operational. Pressing the
“ON–OFF” button again turns the system off.
When the system is turned off, cruising speed must be reset
when the cruise control is turned on again.
When the ignition key is turned off, the “ON–OFF” switch is
also automatically turned off. To use the cruise control again,
push the “ON–OFF” switch again to turn it on.
CAUTION
To avoid accidentally engaging the cruise control, turn
the system off when it is not in use. Make sure the
“CRUISE” indicator light is off.
Setting operation
31X605
 Each function is described below.
1
Setting the cruise speed.
The transmission must be in “D” or “4” before you set the
cruising speed.
Bring the vehicle to the desired speed, press the control lever
downward in the “– SET” direction and release it. This sets the
vehicle at that speed. Now you may take your foot off the
accelerator pedal. If you need acceleration − for example,
when passing − depress the accelerator pedal enough for the
vehicle to exceed the set speed. When you release the
accelerator pe dal, the vehicle will return to the speed set prior
to the acceleration.

2Cancelling the cruise control
The cruise control may be temporarily cancelled by the driver
or by the system itself under certain circumstances.
Temporary cancellation allows the set cruising speed to remain
in memory.
The cruise control can be temporarily cancelled by doing the
following:
 Pulling the lever in the “CANCEL” direction and releasing it
 Depressing the brake pedal
Under certain circumstances, the cruise control is temporarily
cancelled:
 When vehicle speed falls below 40 km/h (25 mph)
 When vehicle stability control is activated
When vehicle speed drops 16 km/h (10 mph) below the set
speed, the cruise control is cancelled and the set speed is
erased from memory.
The “CRUISE” indicator light remains on to indicate that the
system is still in operation.
To turn the cruise control off, push the “ON− OFF” button. Make
sure the “CRUISE” indicator light is off.
If the cruise control automatically cancels out other than for the
above cases, have your vehicle checked by your Lexus dealer
at the earliest opportunity. 3 Resuming the cruise control
If the cruise control is temporarily cancelled, the cruising speed
can be resumed by pushing th e lever up in the “+ RES”
direction.
Vehicle speed must be above 40 km/h (25 mph).
4 Resetting to a faster speed
Press the control lever upward in the “+ RES” direction and
hold it. Release the lever when the desired speed is attained.
While the lever is held upward, the vehicle will gradually gain
speed.
When the difference between the actual vehicle speed and the
set speed is less than 5 km/h (3 mph), the set speed can be
increased 1.6 km/h (1 mph) each time by pressing the control
lever upward in the “+ RES” direction quickly within 0.6
seconds.
However, a quicker way to reset is to accelerate the vehicle
and then press the control lever downward in the “– SET”
direction.

5Resetting to a slower speed
Press the control lever downward in the “– SET” direction and
hold it. Release the lever when the desired speed is attained.
While the lever is held downward, the vehicle speed will
gradually decrease.
When the difference between the actual vehicle speed and the
set speed is less than 5 km/h (3 mph), the set speed can be
lowered 1.6 km/h (1 mph) each time by pressing the control
lever downward in the “– SET” direction quickly within 0.6
seconds.
However, a quicker way to reset is to depress the brake pedal
and then press the control lever downward in the “– SET”
direction.
Even if you turn off the overdrive switch with the cruise control
on, engine braking will not be applied because the cruise
control is not cancelled. To decrease the vehicle speed, reset
to a slower speed with the cruise control lever or depress the
brake pedal. If you use the brake pedal, cruise control is
cancelled.Cruise control failure warning
If the “CRUISE” indicator light flashes when using the cruise
control, press the “ON −OFF” button to turn the system off and
then press it again to turn it on.
If any of the following conditions then occurs, there is some
trouble in the cruise control system.
 The indicator light does not come on.
 The indicator light flashes again.
 The indicator light goes out after it comes on.
If this is the case, contact your Lexus dealer and have your
Lexus inspected.
