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, press 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.3Resuming the cruise control
If the cruise control 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).
4Resetting 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.
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.
However, a quicker way to reset is to depress the brake pedal
and then press the control lever downward in the “ − SET”
direction.
Vehicle with automatic transmission (standard type) —
Even if you downshift the transmission from the “D” position to
“4” with the cruise control on, engine braking will not be
enabled 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.
Vehicle with automatic transmission (multi −mode type) —
Even if you downshift the transmission from the “D” or “5” (fifth
range) to the “4” (fourth range) with the cruise control on,
engine braking will not be enabled 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.

DYNAMIC LASER CRUISECONTROL
Dynamic laser cruise control allows you to drive at a
constant cruising speeds over about 45 km/h (28 mph)
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
cruise control, read and understand the following
instructions.1Cruise control switch

Vehicletovehicle distance control mode
The system’s laser radar sensor detects the reflectors of
vehicles and measures the vehicletovehicle distance.
The detection range of the sensor is about 120 m (400 ft.)
ahead.
CAUTION
Dynamic laser cruise control is not a
collisionavoidance system and will not prevent
accidents. Dynamic laser cruise control is a vehicle
speed control device that is intended for use only on
freeways or roads where the traffic is light or moderate.
To avoid serious injury, you must use caution and be
attentive to road and traffic conditions while using
dynamic laser cruise control.
(a) Dynamic laser cruise control operations

STARTING AND DRIVING
421
CAUTION
Do not rely excessively on dynamic laser cruise control.
Observe the following precautions in order to avoid
serious injury or death:
 Under certain conditions when the vehicle in front
slows abruptly, or is stopped, the dynamic laser
cruise control may be unable to decelerate
automatically or to warn you. You must apply the
brakes manually in order to maintain a safe
vehicletovehicle distance or avoid collision.
Therefore, pay careful attention to following
distance, even when using the dynamic laser cruise
control.
 Do not use dynamic laser cruise control in the
following conditions:
In bad weather (such as rain, fog, snow, sandstorms
or direct sunlight, or when raindrops or snowflakes
get on the laser radar sensor glass), the
vehicletovehicle distance will not be measured
accurately.
When using the windshield wipers at high or low
speeds, the dynamic laser cruise control turns off.
On roads with heavy traffic or sharp bends, an
appropriate speed cannot be maintained and an
accident may occur.
On slippery road surfaces (icy or snowcovered road
surfaces), the tires will race and you will be unable to
control the vehicle.
When there is no vehicle detected ahead on steep
downhill slopes, the preset speed will be easily
exceeded because of inefficient engine braking. (In
this case, automatic braking will not work.) If there is
a vehicle detected ahead, the delay in deceleration
timing could cause serious injury or death.
When the alarm sounds frequently (because of
frequent changes of speed or insufficient
vehicletovehicle distance), this indicates that the
system cannot maintain an appropriate
vehicletovehicle distance and an accident may
occur.
On roads with steep and short inclines and declines,
failure to detect the vehicle ahead will shorten the
distance between your vehicle and the vehicle ahead
and an accident may occur.

STARTING AND DRIVING
423
If other vehicles are driving outside of the laser radar
detection range, a delay in the detection of the
vehicle cutting in at short range or failure to detect a
motorcycle running on the side of the same lane will
occur. In this case, the dynamic laser cruise control
system will not function properly.
 When a slower vehicle in front of you leaves the lane,
the dynamic laser cruise control will no longer detect
a vehicle ahead and will attempt to accelerate the
vehicle to the faster preset speed.
(b) Turning the system on and off
To turn the dynamic laser cruise control on, press the
“ON−OFF” button. The “CRUISE” and “READY” indicator
lights on the instrument cluster will come on to indicate that the
vehicle −to−vehicle distance control mode is operational.
Pressing the “ON −OFF” button again turns the system off.
When the system is turned off, cruising speed and
vehicle −to−vehicle distance must be reset when the
vehicle −to−vehicle distance control mode is turned on again.
When the ignition is turned off, the system is also automatically
turned off. To use dynamic laser cruise control again, press the
“ON−OFF” button again to turn it on.
When the ignition is turned off, all the preset data is cleared.
When you use the dynamic laser cruise control again, you
need to reset the data.

STARTING AND DRIVING
424
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.
(c) Setting the cruising speed
The transmission must be in the “D” position or the shift range
position must be “4” (fourth range) or “5” (fifth range) in “\
S”
mode (with multi−mode type) before you set the cruising
speed.

STARTING AND DRIVING
425
Bring your vehicle to the desired speed, push the lever down
in the “−
SET” direction and release it. This sets the vehicle at
that speed. At this time, the display indicates settings such as
the preset vehicle speed, whether a vehicle is present ahead
and the selected following distance. If no vehicle is detected
ahead, the display does not indicate the vehicle ahead. You
can now take your foot off the accelerator pedal.
If you need to accelerate — for example, when passing —
depress the accelerator pedal enough for the vehicle to exceed
the preset speed. When you release the accelerator pedal, the
vehicle will return to the control prior to acceleration.
You cannot set a desired speed if the master warning light
comes on, the alarm sounds and the display indicates one of
the warning codes “E1”, “E2” or “E3”. If any of the above codes
appears on the display, see “(l) Vehicle −to−vehicle distance
control mode failure warning” on page 431. (d) Cancelling the vehicletovehicle distance control
mode
The vehicle
−to−vehicle distance control mode may be
temporarily cancelled by the driver or by the system itself under
certain circumstances. Temporary cancellation allows the set
cruising speed and vehicle −to−vehicle distance to remain in
memory.
The vehicle −to−vehicle distance control mode 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 vehicle −to− vehicle distance
control mode is temporarily cancelled:
 When vehicle speed falls below 40 km/h (25 mph)
 When vehicle stability control is activated
The “READY” indicator light comes on to indicate that the
system is still in operation.
To turn the system off, press the “ON −OFF” button. Make sure
the “CRUISE” indicator light is off.
If one of the warning codes “E1”, “E2” or “E3” appears\
on the
display, the preset speed automatically cancels out. See “(l)
Vehicle −to−vehicle distance control mode failure warning” on
page 431.
If the vehicle− to−vehicle distance control mode automatically
cancels out other than for the above cases, have your vehicle
checked by your Lexus dealer at the earliest opportunity.

1Warning code2 “CRUISE” indicator light
3Master warning light
If a system malfunction is detected when the
vehicle −to−vehicle distance control mode is on, the master
warning light comes on, a warning tone sounds and a warning
code appears on the display. Dynamic laser cruise control is
automatically cancelled.
If “E3” appears on the display, the “CRUISE” indicator light in
the instrument cluster also flashes. If “E1” appears on the display,
the system cannot easily
measure the vehicle −to−vehicle distance because of a dirty
laser radar sensor glass.
If this code appears, clean the sensor glass with a soft cloth
and try setting the preset speed again. If the dirt is removed
without cleaning, the system will automatically enter the ready
mode.
If the system does not enter the ready mode even after
cleaning or the code remains on the display, the system might
be malfunctioning. Although the vehicle may still be operated,
please contact your Lexus dealer.
CAUTION
Always keep the sensor glass clear and never allow it to
be covered with icicle or any substance, so it can detect
the vehicle in front.

STARTING AND DRIVING
432If “E2” appears on the display,
the system may be having
trouble measuring the vehicle −to− vehicle distance because of
any of the following:
 The wipers are operating at high or low speeds
 Direct sunlight from the front
 It is difficult to make a measurement because of bad
weather (such as rainy, foggy, or snowy weather)
 Driving in “SNOW” mode
In the following cases, dynamic laser cruise control switches
to the ready mode:
 The wipers are stopped or are switched to variable
intermittent operation.
 No direct sunlight from the front
In the above conditions, push the lever up in the “+ RES”
direction and release it. Dynamic laser cruise control will be
restored. If the setting operation cannot be performed or if the
same code still appears even after the weather clears, the
system might have malfunctioned. Although there is no
problem to continue driving, please contact your Lexus dealer. If “E3” appears on the display,
a system malfunction has
been detected.
If this warning code appears, stop your vehicle in a safe place,
turn the ignition off, and then restart it to reset the system. If
the same code appears again or if the cruise control cannot be
set, the system may be malfunctioning. Although there is no
problem to continue driving, please contact your Lexus dealer.
