CAUTION
In the conventional (fixed speed) cruise control
mode, an approach warning does not activate even if
you are too close to the vehicle ahead, as neither the
presence of the vehicle ahead nor the
vehicle−to−vehicle distance is detected. Pay special
attention to the distance between your vehicle and
the vehicle ahead. Always confirm the setting in the
multi−information display.
The conventional (fixed speed) cruise control mode
of the dynamic radar cruise control should not be
used in the following conditions, which could result
in death or serious injury.
♦To help maintain maximum control of your vehicle,
do not use fixed speed control mode when using
dynamic radar cruise control while driving in
heavy or varying traffic, or on slippery (rainy, icy
or snow−covered) or winding roads.
♦Avoid vehicle speed increasing when driving
downhill. If the vehicle speed is too fast in relation
to the preset speed in the fixed speed control
mode, cancel the fixed control mode and then
downshift the transmission to use engine braking
to slow down.
(a) Turning the system on
g31001
To operate conventional cruise control mode, push the
“ON−OFF” button. This turns the system on. The “CRUISE”
indicator light in the instrument cluster comes on and “RADAR
READY” appears on the multi−information display. Push the
control lever in the “MODE” direction for longer than 1 second
to change to conventional cruise control mode. The indicator
on the multi−information display is as shown. You can now set
your desired cruising speed. Pushing the “ON−OFF” button
again will turn the system completely off and “CRUISE OFF”
will appear on the multi−information display.
However, once the vehicle−to−vehicle distance control mode
activates and is used, it cannot be changed to the conventional
(fixed speed) cruise control mode using the above operation.
To change the mode, push the “ON−OFF” button to turn the
system off and then push it again to turn it on. Next push the
lever in the “MODE” direction for longer than about 1 second.

STARTING AND DRIVING
414When the engine switch is turned off, the system is also
automatically turned off. To use the dynamic radar cruise
control again, push the “ON−OFF” button again to turn it on.
CAUTION
To avoid accidentally engaging cruise control , keep the
“ON−OFF” button off when not using dynamic radar
cruise control.
(b) Setting operation
g31002

Each function is described below.
1
Setting the desired speed
The transmission must be in “D”, “6” (sixth range), “5” (fifth
range) or “4” (fourth range) before you set the cruise control
speed in the conventional cruise control mode of the dynamic
radar cruise control.
After bringing 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 and the multi−information
display shows the preset speed. At this time, you may 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
speed set prior to acceleration.

STARTING AND DRIVING
415 You cannot set a desired speed if the master warning light
comes on, the warning tone sounds and the multi−information
display indicates a warning message such as “CHECK
CRUISE SYSTEM”. If this messages appears on the display,
see “Conventional cruise control mode failure warning” on
page 417.
If you turn off the “ON−OFF” button while the warning message
is displayed, the warning message turns off and the
multi−information display switches to another screen. When
you turn the “ON−OFF” button on again, the warning message
comes back on the display. If no warning message appears on
the display, the setting can be made.
You can change the dynamic radar cruise control screen to
another screen even while the warning message is displayed.

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 cancelled by a. or b., the multi−information displays shows
nothing and the conventional cruise control enters the ready
mode.
If cancelled by c., the “CRUISE” indicator light goes off in the
instrument cluster and the multi−information display shows
“CRUISE OFF”. In this case, the preset speed data is cleared,
and you must set the speed from the beginning.In the following cases, the preset speed automatically
cancels out:
a. The vehicle speed falls below about 40km/h (25 mph).
b. If the vehicle speed drops 16 km/h (10 mph) below the
preset speed, the preset speed will also automatically be
cancelled.
c. The control lever is pressed downward in the “– SET”
direction and held at less than about 45 km/h (28 mph). (45
km/h (28 mph) is designated as a lower preset speed limit .)
If the vehicle speed falls below about 40 km/h (25 mph), the
preset speed data is cleared and you must set the speed from
the beginning.
If cancelled by the above cases, the multi−information display
shows nothing and the conventional cruise control enters the
ready mode.
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.

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.
(c) Conventional cruise control mode failure warning
G13075
If the system malfunction is detected when the
conventional cruise control mode is in the ready mode or
operating, the master warning light comes on, a warning
tone sounds and the above message appears.
If this message appears, push the “ON−OFF” button to turn the
system off and then push it again to turn it on. If the setting still
cannot be made or the same message appears again, the
system might have malfunctioned. Although it is no problem
to continue driving, contact your Lexus dealer.
