2Cancelling the preset speed
You can cancel the preset speed by either of the following:
a. Pulling the control lever in the “CANCEL” direction.
b. Depressing the brake pedal.
c. Pushing the “ON −OFF” button.
If the vehicle speed falls below about 40 km/h (25 mph), the
preset speed will be automatically cancelled.
If the vehicle speed drops 16 km/h (10 mph) below the preset
speed, the preset speed will also automatically be cancelled.
If the slip indicator light blinks and a warning tone sounds, the
preset speed will be automatically cancelled.
If the preset speed automatically cancels out for other than the
above reasons, do not operate the cruise control. Although it
is no problem to continue driving, have your vehicle checked
by your Lexus dealer at the earliest opportunity.
3 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.
4
Resetting to a slower speed
Press the co ntrol 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.
With the cruise control on, even if you downshift the
transmission from the “D” position or “6” (sixth range) to the “5”\
(fifth range), or from the “D” position or “5” (fifth ran\
ge) to the
“4” (fourth range), 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.

5Resuming the preset speed
If the preset speed is cancelled by pulling the control lever, by
depressing the brake pedal or vehicle stability control
activation, pushing the lever up in the “+ RES” direction will
restore the speed set prior to cancellation. However, once the
vehicle speed falls below about 40 km/h (25 mph), the preset
speed will not be resumed.
Cruise control failure warning
If the “CRUISE” indicator light in the instrument cluster flashes
when using the cruise control, push the “ON −OFF” button to
turn the system off and then push 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 RADAR/LASER CRUISE CONTROL
The vehicles with precollision safety system are
equipped with dynamic radar cruise control. For the
vehicles without precollision safety system, dynamic
laser cruise control can be equipped as optional.
Dynamic radar/laser cruise control allows you to drive at
a selected cruising speed over about 45 km/h (28 mph)
with your foot off the accelerator pedal, maintaining an
appropriate vehicletovehicle distance.

5 Cruise control lever
The dynamic radar/laser cruise control function has 2 cruise
control modes: vehicle−to−vehicle distance control mode for
maintaining an appropriate distance between vehicles, and a
conventional (fixed speed) cruise control mode for cruising at
preset speeds.

STARTING AND DRIVING
334If no vehicle is running ahead of you:
1
Cruising at a fixed speed: If there is no vehicle detected
ahead, your cruising speed is maintained at the preset
speed from about 45 km/h (28 mph) to about 135 km/h (85
mph). The preset speed is displayed in the
multi−information display. For the vehicle speed setting,
see “Setting operation ” on page 340.
If a vehicle is detected ahead of you:
2 Deceleration cruising function: If a slower moving
vehicle is detected ahead of you, your vehicle cruising
speed decreases within the range of about 40 km/h (25
mph) to about 135 km/h (85 mph). The multi− information
display shows the preset speed, the detected vehicle
ahead and selected vehicle− to−vehicle distance. If your
vehicle gets closer to the vehicle ahead because of
insufficient automatic deceleration, then the warning tone
warns you to also manually apply brakes.
3 Followup cruising function: After deceleration, your
vehicle cruising speed changes in proportion to the speed
of the vehicle ahead to maintain an appropriate distance
from your vehicle to the vehicle ahead. The
vehicle −to−vehicle distance can be changed. For details,
see “Changing vehicle −to−vehicle distance setting” on
page 346.
4 Acceleration cruising function: If the vehicle ahead
changes lanes, your vehicle cruising speed will be
gradually increased up to the preset speed, and your
vehicle resumes fixed −speed cruising.
CAUTION
Under certain conditions where the vehicle in front
slows drastically, or is stopped, the dynamic radar/laser
cruise control will neither warn you nor decelerate. The
driver must depress the brake pedal to slow down,
ensuring collision avoidance or that sufficient
vehicletovehicle distance is maintained.
When vehicle −to−vehicle distance control mode is activated,
you must still be attentive to road and traf fic conditions. Should
your vehicle speed decrease below about 40 km/h (25 mph),
the dynamic radar/laser cruise control will shut off, requiring
you to apply the brakes to slow. When a vehicle ahead slows
suddenly, stops or a vehicle cuts in front, the system may slow
your vehicle abruptly, but the automatic braking will cease if the
speed decreases below about 40 km/h (25 mph) requiring the
driver’s manual application of brakes.

STARTING AND DRIVING
336
Dynamic radar cruise control should not be used in the
following conditions, to avoid death or serious injury.
In bad weather (such as rain, fog, snow , sandstorms,
or when raindrops or snowflakes get in the millimeter
wave radar sensor or the grille cover), the
vehicletovehicle distance will not be measured
accurately.
If the wipers are operated at high speed (including the
high speed operation with the wiper lever in the
“AUTO” position), dynamic radar cruise control is
automatically cancelled. (In the case of the low speed
operation and intermittent wiper operation, it is not
cancelled.) Dynamic radar cruise control is
automatically cancelled when the measurement is
extremely unstable due to bad weather.
 On the roads in heavy traffic or at sharp bends:
As an appropriate speed cannot be maintained, death
or serious injury could result.
 On slippery road surfaces (icy or snowcovered road
surfaces):
The tires will race and you will be unable to control.On steep downhill slopes:
If there is no vehicle detected ahead, the preset speed
will be easily exceeded because of inefficient engine
braking, resulting in death or serious injury. (In this
case, automatic braking will not work.) If there is a
vehicle detected ahead, the delay in deceleration
timing could cause death or serious injury.
 When the warning tone sounds frequently (because
acceleration or deceleration was repeated or
sufficient vehicletovehicle distance was not
maintained), an appropriate vehicle speed cannot be
attained, resulting in death or serious injury.
 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,
resulting in death or serious injury.
