Both obstacles detected on the front and rear of the
vehicle are in areas where continuous beeping
should sound:
If the possibility of collision with the obstacles is very high as
shown, the system warns the driver by continuous beeping
(repeating 2 quick beeps and one longer beep as one cycle).
CAUTION
It might be difficult to hear beeps due to the volume of
audio or air flow noise of air conditioning. To avoid an
accident or injury, drive slowly using the brakes while
confirming a safe distance around your vehicle with
your eyes.

REAR VIEW MONITOR SYSTEM
The rear view monitor system assists the driver by
displaying an image of the rear of the vehicle while
backing up. The displayed image on the screen is a
horizontally reversed mirror image of the inside rear view
mirror.
To display the rear view image on the screen, place the
selector lever in the “R” position when the engine switch
is selected in “IG−ON” mode.
If you move the selector lever out of the “R” position, the screen
returns to the previous screen. Operating another function of
the navigation system will display another screen.
The rear view monitor system is a supplemental device
intended to assist back up. When backing up, be sure to check
behind and all around the vehicle visually.
Vehicles with intuitive parking assist—
When the intuitive parking assist is turned on and an obstacle
is detected in front or rear of your vehicle, a warning appears
on the right top of the rear view monitor. For details, see
“Intuitive parking assist” on page 365.

STARTING AND DRIVING

Setting operation
G31164

Each function is described below.
1
Setting at a desired speed.
The transmission must be in the “D” position, or the shift range
position must be “4” (fourth range), “5” (fifth range) or “6” (sixth
range) in the “S” mode before you set the cruise control 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 pedal, the vehicle will return to the speed set prior
to the acceleration.
2
Cancelling the preset speed
You can cancel the preset speed by doing any 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.

STARTING AND DRIVING
394However, 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 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.
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 range) 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.
5
Resuming 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.
