2006 LEXUS RX330 reset

STARTING AND DRIVING
422
Deceleration cruising function and approach
warning do not operate when the vehicle ahead is at
a stop or driving very slowly.
 If the vehicle ahead of you decelerates abruptly or if
another vehicle cuts in ahead of you, your vehicle
may collide with the vehicle ahead unless you
manually depress the brake pedal to slow down your
vehicle.
 Depending on the road configuration (curved, left
and right continuous curved, the start or end of a
curve, or narrow driving lanes due to road
construction) or your vehicle condition (steering
wheel maneuvering, position in the lane, or unstable
driving because of an accident or breakdown),
vehicles in other lanes or surrounding objects may
be detected, resulting in a control failure or the
approach warning activation. This may also result in
a very close distance between vehicles due to a
failure to detect the vehicle ahead.
Dynamic laser cruise control should not be used in
circumstances which are inappropriate for any cruise control,
such as entering free way on− ramps or off−ramps.
CAUTION
Do not use dynamic laser cruise control when exiting
from or when entering or merging onto a freeway.
When you are following a slower moving vehicle and
exiting, the sensor does not detect the vehicle and
will accelerate to the preset speed.

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
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.

STARTING AND DRIVING
426(e) Resuming the vehicletovehicle distance control
mode
If the vehicle
−to− vehicle distance control mode is temporarily
cancelled, the cruising speed and vehicle −to− vehicle distance
can be resumed by pushing the lever up in the “+ RES”
direction.
Vehicle speed must be above 40 km/h (25 mph).
In vehicle −to−vehicle distance control mode, when vehicles
ahead leave your lane, your vehicle will gradually accelerate
up to the preset speed. Pushing the lever up in the “+RES”
direction returns your vehicle to the preset speed mode quickly. (f) Resetting to a faster speed
Push the lever up in the “+ RES” direction and hold it. The
displayed speed will increase in increments of 5 mph (for the
U.S.A.) or 5 km/h (for Canada). Release the lever when the
desired speed is attained. The vehicle speed will gradually
increase to the displayed speed.
However, a
faster way to reset is to accelerate the vehicle and
then push the lever down in the “ − SET” direction.
CAUTION
When the vehicletovehicle distance control is on,
your cruising speed is regulated to match the speed of
the vehicle ahead. Increasing the preset speed using
the control lever does not accelerate the vehicle.
However, if the vehicle ahead leaves your lane, your
cruising speed will increase to the speed set with the
control lever. Confirm the setting on the display.

STARTING AND DRIVING
427
(g) Resetting to a slower speed
Push the lever down in the “
− SET” direction and hold it. The
displayed speed will decrease in increments of 5 mph (for
U.S.A.) or 5 km/h (for Canada). Release the lever when the
desired speed is attained. The vehicle speed will gradually
decrease to the displayed speed.
However, a faster way to reset is to depress the brake pedal
and then push the lever down in the “ − SET” direction.
If the control lever is released when the vehicle speed exceeds
the upper limit of the preset speed traveling downhill while you
are pushing the lever down, the system will memorize the
upper limit of the preset speed as a preset speed.
With automatic transmission (standard type) —
Even if you downshift the transmission from “D” to “4” in th\
e
vehicle −to−vehicle distance control mode, engine braking will
not be enabled because this mode 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.
With automatic transmission (multi −mode type) —
Even if you downshift the transmission from “D” or “5” (fif\
th
range) to the “4” (fourth range) in the vehicle −to−vehicle
distance control mode, engine braking will not be enabled
because this mode 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. (h) Changing vehicletovehicle distance
1Long2Middle3Short
You can select one of the distances listed below.
1. Long
2. Middle
3. Short
Pulling the distance switch briefly towards you allows you to
toggle between long, middle and short vehicle −to−vehicle
distances. You can confirm the setting on the display.
Your vehicle speed changes to match the speed of the vehicle
ahead, maintaining the selected distance. However, if the
vehicle ahead slows, the actual vehicle −to−vehicle distance
will be shorter than the set distance.
When the vehicle−to−vehicle distance control mode is
activated or the “READY” indicator comes on, the
vehicle −to−vehicle distance setting can be changed.

warning
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.

STARTING AND DRIVING
433
Conventional (fixed speed) cruise control
mode
The conventional cruise control mode is designed to
maintain a set cruising speed without requiring the driver
to operate the accelerator. Cruising speed can be set to
any speed above 45 km/h (28 mph).
Within the limits of the engine’s capabilities, cruising speed can
be maintained up or down grades. However, changes in
vehicle speed may occur on steeper grades.
CAUTION
 In the conventional cruise control mode, the
approach warning does not activate and no alarm will
sound even if you are too close to the vehicle ahead,
as neither the presence of the vehicle ahead nor the
vehicletovehicle distance is detected. Pay special
attention to the distance between your vehicle and
the vehicle ahead. Always confirm the cruise control
mode on the display.
 Do not use the conventional mode in the following
conditions, or serious injury or death could result:
To help maintain maximum control of your vehicle,
do not use conventional cruise control mode when
using dynamic laser cruise control while driving in
heavy or varying traffic, or on slippery (rainy, icy or
snowcovered) 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 conventional cruise control
mode, cancel the conventional cruise control mode
and then downshift the transmission to use engine
braking to slow down.
