with your foot off the accelerator pedal, maintaining an
appropriate vehicletovehicle distance between the
vehicle ahead.
CAUTION
Do not rely excessively on dynamic laser cruise control
in order to avoid serious injury or death, or to prevent
accidents or to control the vehicle’s speed in
emergency situations. Do not use cruise control except
in appropriate road and traffic conditions. Always drive
carefully and attentively. Before using dynamic laser

CAUTION
Braking control will not ensure that your vehicle will
reduce speed appropriately. You must depress the
brake pedal to slow down, in order to avoid a collision
or to maintain sufficient vehicletovehicle distance.
(j) Approach warning
While you are cruising in the vehicle−to−vehicle distance
control mode, if the vehicle ahead decelerates abruptly or if
another vehicle cuts in ahead of you, your vehicle may come
closer to the vehicle ahead. The display will flash and beep to
alert you.
CAUTION
 If the display flashes and beeps, this indicates that
you must depress the brake pedal in order to slow
down sufficiently to avoid a collision or maintain
appropriate vehicletovehicle distance.
 In the following conditions, the approach warning
may not turn on even if the vehicle drives closer to the
vehicle ahead, and an accident may occur:
Your vehicle and the vehicle ahead are cruising at
almost the same speed.
The vehicle ahead is cruising at a faster speed than
yours. (The distance between the vehicles will
become longer.)
The vehicle ahead is at a stop or driving very slowly.
Pay special attention to a very slow vehicle at the end
of the line in heavy traffic or at a tollgate.
The speed has just been set.
The accelerator pedal is depressed or has just been
released.

STARTING AND DRIVING
434(a) Turning the system on and off
To turn the conventional cruise control mode on, press the
“ON−OFF” button. The “CRUISE” and “READY” indicator
lights on the
instrument panel will come on. Push the lever in
the “MODE” direction for longer than 1 second to change to
conventional cruise control mode. The indicator on the
instrument panel is as shown. You can now set the cruising
speed. Pressing the “ON− OFF” button again turns the system
off.
When the system is turned off, cruising speed must be reset
when the conventional cruise control mode is turned on again.
However, once the vehicle −to−vehicle distance control mode
activates and is used, the system cannot be changed to the
conventional cruise control mode using the above operation.
To change the mode, you must turn this system off and then on
again. Next pu sh the lever in the “MODE” direction for longer
than about 1 second. To change to the vehicle
−to−vehicle distance control mode
from the conventional cruise control mode, push the lever in
the “MODE” direction for longer than about 1 second.
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.

STARTING AND DRIVING
436To turn the system off, push the “ON
−OFF” button. Make sure
the “CRUISE” indicator light is off.
If the conventional cruise control mode automatically cancels
out other than for the above cases, have your vehicle checked
by your Lexus dealer at the earliest opportunity.
(d) Resuming the conventional cruise control mode
If the conventional cruise control mode is temporarily
cancelled, the cruising speed can be resumed by pushing the
lever up in the “+ RES” direction.
Vehicle speed must be above 40 km/h (25 mph).
(e) Resetting to a faster speed
Push the lever up in the “+ RES” direction and hold it. Release
the lever when the desired speed is attained. While the lever
is held up, 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 pushing the lever up
in the “+ RES” direction quickly within 0.6 seconds.
However, a faster way to reset is to accelerate the vehicle and
then push the lever down in the “ − SET” direction. (f) Resetting to a slower speed
Push the lever down in the “
− SET” direction and hold it.
Release the lever when the desired speed is attained. While
the lever is held down, 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 pushing the lever down
in the “− SET” direction quickly within 0.6 seconds.
However, a faster way to reset is to accelerate the vehicle and
then push the lever down in the “ − SET” direction.
With automatic transmission (standard type) —
Even if you downshift from “D” to “4” in the conventional cruise
control mode, engine braking will not be enabled because this
mode is not cancelled. To decrease the vehicle’s 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.
With automatic transmission (multi −mode type) —
Even if you downshift from “D” or “5” (fifth range) to “4” (fourth
range) in the conventional cruise control mode, engine braking
will not be enabled because this mode is not cancelled. To
decrease the vehicle’s 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.

This mode is suitable for driving on bumpy roads.
When the vehicle speed exceeds approximately 50 km/h (31
mph) or driving at the speeds of 30 km/h (19 mph) or over for
ten seconds total in “HI” mode, “N” mode is automatically
selected. Even if the vehicle speed then reduces to under 50
km/h (31 mph), the vehicle’s height will not return to “HI” mode.
CAUTION
The “HI” mode should be used for severe offroad
driving conditions only. As the vehicle’s center of
gravity is higher in this setting, the vehicle may become
unstable when turning abruptly, resulting in an
unexpected accident.

(h) Parking and stopping tips
If you immediately stop the engine to park the vehicle after
off−road driving, the vehicle height is lowered slightly as the
vehicle becomes cool. When parking, make sure there is
nothing that will be in contact with the underbody of the vehicle.
If the “HI” (high) mode is selected when you start the engine,
the vehicle returns to the “HI” (high) height. If the “LO” (\
low) or
“N” (normal) mode is selected when you start the engine, the
vehicle height is change to “N” (normal) mode.
If you park the vehicle for a long time, the vehicle height may
be gradually lowered. When parking for a long time, make sure
there is nothing that will be in contact with the underbody of the
vehicle. If the “HI” (high) mode is selected when you start the
engine, the vehicle returns to the “HI” (high) height. If the “LO”\
(low) or “N” (normal) mode is selected when you start the
engine, the vehicle height is change to “N” (normal) mode.
If you stop the engine, the vehicle height may change in
accordance with the change in the temperature. When you
start the engine, the vehicle returns to the “HI” (high) height.\
If the “LO” (low) or “N” (normal) mode is selected when \
you
start the engine, the vehicle height is change to “N” (normal)
mode.
TRACTION CONTROL SYSTEM
(twowheel drive models)
The traction control system automatically helps prevent
the spinning of front wheels when the vehicle is started or
accelerated on slippery road surfaces.
When the ignition key is turned to “ON”, the system
automatically turns on.
CAUTION
Under certain slippery road conditions, full traction of
the vehicle and power against front wheels cannot be
maintained, even though the traction control system is
in operation. Do not drive the vehicle under any speed
or maneuvering conditions which may cause the
vehicle to lose traction control. In situations where the
road surface is covered with ice or snow, your vehicle
should be fitted with snow tires or tire chains. Always
drive at an appropriate and cautious speed for the
present road conditions.
