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.

STARTING AND DRIVING
276
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.

STARTING AND DRIVING

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.

STARTING AND DRIVING
278
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.

ACTIVE HEIGHT CONTROLSUSPENSION (AHC)
This active height control suspension controls the vehicle
height depending on the vehicle driving condition. Select
your desired height among the “HI” (high), “N” (normal)
and “LO” (low) modes with the height select switch.
31X600
(a) Vehicle height modes
 “HI” (high) mode
The vehicle height is about 40 mm (1.6 in.) higher at front
and about 50 mm (2.0 in.) higher at rear than the normal
mode height.
This mode is suitable when driving on bumpy roads and
through water.
This mode is available when the vehicle speed is under about
30 km/h (19 mph).
CAUTION
The “HI” (high) or “Extra high” mode should be used for
severe offroad driving condition only. Because the
vehicle’s center of gravity is higher in this setting, the
vehicle may become unstable when turning abruptly,
resulting in an accident.
When the four −wheel drive control lever is put at “L”, this mode
may change to the extra high mode automatically in
accordance with the driving condition.
When the vehicle exceeds the specified vehicle speed, the
vehicle height changes to the following:
With the fourwheel drive control lever at “H” and at the
vehicle speed of 30 km/h (19 mph) or over, the normal mode
is automatically selected.
With the fourwheel drive control lever at “L” and at the
vehicle speed of 50 km/h (30 mph) or over, the vehicle
height becomes automatically about 25 mm (1.0 in.) higher
than the normal mode height. If the vehicle speed is lowered
about 20 km/h (12 mph) or le ss after that, the high mode
automatically resumes.
Extra high mode
This mode is automatically selected from the high mode
with the fourwheel drive control lever placed in “L”
position depending on the vehicle driving condition.
If the vehicle becomes stuck, the vehicle height rises
automatically to the extra high mode (slightly higher or at about
70 mm (2.8 in.) higher than normal mode height).

STARTING AND DRIVING
280In the following cases, the extra high mode changes to the high
mode automatically:

When your vehicle is no longer stuck.
 When the four −wheel drive control lever is put in a position
other than “L”.
When you push the height select switch on the “
” side
in the extra high mode, the normal mode is selected.
Since the extra high mode is automatically selected, you
cannot select this mode on purpose with the height select
switch.
 “N” (normal) mode
The vehicle height in this mode is standard.
This mode is suitable for ordinary driving.
 “LO” (low) mode
The vehicle height is about 50 mm (2.0 in.) lower at front
and about 40 mm (1.6 in.) lower at rear than the normal
mode height.
This mode allows you easy access to the vehicle (getting in
and out) and easy loading and unloading operation.
This mode is available when the vehicle is stopped. When you
start the vehicle, the normal mode is automatically selected.
NOTICE
The normal mode is automatically selected when the
vehicle begins to move in the low mode. So be careful
when you drive in any place where the overhead height
is limited.
(b) Automatic leveling function
Regardless of the number of occupants or the luggage
loading condition, the vehicle height is always
automatically adjusted to a fixed height in any mode.
However, the vehicle height cannot be raised if the vehicle load
exceeds the limits. (See page 281.)
(c) Vehicle height mode changing condition
To change the vehicle height, it is necessary to meet the
following 3 conditions.
 The engine should be running.
 All the side doors and back door should be closed.
 The height control “OFF” indicator light should go off.
When selecting a mode with the four −wheel drive control lever
at “H”, there is a vehicle speed limit. Refer to the following
table.

In the following cases the active height control
suspension does not operate even if the above conditions
are all met.
 The brake pedal has been depressed for longer than about
5 seconds with the vehicle stopped.
 The suspension fluid temperature is lower than −30 C
(−22 F). If the engine is warmed up, the suspension fluid
temperature will be raised as the inside of the engine
compartment becomes warmer. Then the active height
control suspension becomes operable.
 Driving on bumpy roads, which may cause the suspension
to fully elongate.
 The steering wheel is operated abruptly more than 3/4 turn
with center differential lock system activated.

To change the mode, push the height select switch on
either side of “ ” and “
”.
The height control indicator light indicates which mode is
selected. (See page 284.)
NOTICE
 If you change the vehicle height frequently, the pump
may overheat. To prevent this, the active height
control suspension should be stopped temporarily
for a minute between selections. Operate it again.

STARTING AND DRIVING
282
Before you lower the vehicle height with the height
select switch, check under the vehicle to make sure
that nothing to damage the vehicle or no one to be
injured is there and the underbody of the vehicle
does not touch the ground.
 After unloading, the height of a vehicl e equipped with
the active height control suspension becomes
slightly higher than the normal vehicle height. Take
sufficient care where the overhead height is
restricted.
The vehicle height cannot be raised if the vehicle load
exceeds the following limits:
 Up to 4 occupants* plus about 300 kg (661 lb.) in the normal
mode
 Up to 4 occupants* plus about 170 kg (375 lb.) in the high
mode
*About 68 kg (150 lb.) for a person
If the above load capacity is exceeded, the desired vehicle
height may not be obtained even if the height select switch is
pushed. (If the vehicle height cannot be raised in the normal
mode and the height control indicator indicates “LO”, this is
because the vehicle is loaded too heavily. Under these
conditions, drive your vehicle with due care.)
If the vehicle height cannot be raised even after unloading,
push the height select switch on the “
” side and then on the
“ ” side. If this does not work, turn off the ignition once and
then turn on. Operate the select switch again. If the vehicle height is adjusted on the slope, or with the
selector lever in a position other than “P” or “N” while the\
vehicle is stopped, you may h
ear a sound caused by the
expansion and contraction of the propeller shaft.
 Selecting the high mode:
Push the height select switch on the “ ” side when the vehicle
speed is under about 30 km/h (19 mph).
To change the normal mode to high, push the switch once.
To change the low mode to high, push the switch twice. It
takes about 30 seconds until the low mode changes to the high
mode.
 Selecting the normal mode:
To change the high mode to normal, push the height select
switch on the “
” side once.
To change the low mode to normal, push the height select
switch on the “ ” side once.
 Selecting the low mode:
Push the height select switch on the “
” side while the vehicle
is stopped.
To change the high mode to low, push the switch twice.
To change the normal mode to low, push the switch once.
