2006 LEXUS RX330 cruise control

STARTING AND DRIVING
3923. Release the parking brake and brake pedal. Depress
the accelerator pedal slowly for smooth starting.
In normal cruising, the vehicle will start in first gear and
automatically shift up to the most suitable gear. On inclines,
declines
or winding roads, etc., the vehicle shifts up and down
automatically according to the running conditions to obtain the
suitable driving power and engine braking.
When the lever is in the “4” position, the automatic
transmission system will select the most suitable gear for the
running conditions such as hill climbing, hard towing, etc.
If you need to accelerate rapidly while driving, depress the
accelerator pedal to the full throttle position. This provides
more acceleration by automatically downshifting the
transmission to the next lower gear or beyond, depending on
the vehicle speed.
If engine braking is needed, such as in descending a long hill,
see “(b) Using engine braking”.
(b) Using engine braking
To use the braking power of the engine, downshift the
transmission in the way described below:
1Shift into the “4” position. The transmission will downshift
to fourth gear and engine braking will be enabled.
Vehicle with the cruise control —
When the cruise control is being used, even if you
downshift from “D” to “4”, engine braking will not be
enabled because the cruise control is not cancelled. For
vehicle speed reduction, see page 415.

Vehicle with the dynamic laser cruise control —
When
the cruise control is being used in the conventional
(fixed speed) cruise control mode or in the
vehicle −to−vehicle distance control mode, even if you
downshift from “D” to “4”, engine braking will not be
enabled because the cruise control is not cancelled. For
vehicle speed reduction, see pages 427 and 436.
2Shift into the “3” position. The transmission will downshift
to third gear when the vehicle speed is or becomes lower
than 129 km/h (81 mph) and stronger engine braking will
be enabled.
3Shift into the “2” position. The transmission will downshift
to second gear when the vehicle speed is or becomes
lower than 83 km/h (52 mph) and more powerful engine
braking than that of “3” position will be enabled.
4Shift into the “L” position. The transmission will downshift
to first gear when the vehicle speed is or becomes lower
than 39 km/h (24 mph) and maximum engine braking will
be enabled.
CAUTION
Be careful when downshifting on a slippery surface.
The abrupt change in engine speed could cause the
vehicle to skid or spin.

(c) Using engine braking
“S” mode position
To use the braking power of the engine, downshift the range in
the “S” mode position as follows:
 Shift into the “4” (fourth range) position. The transmission
will downshift to fourth gear and engine braking will be
engaged.
If you drive in the “D” position: Shift the selector lever to
the “S” position and “4” (fourth range) will automatically\
be
selected.
If you drive in the “S” position: Shift the selector lever
down to the “ −” position by selecting the “4” (fourth range). Vehicles with the cruise control —
When
the cruise control is being used, even if you downshift
from “D” or “5” (fifth range) to “4” (fourth range)\
, engine
braking will not be enabled because the cruise control is not
cancelled. For vehicle speed reduction, see page 415.
Vehicles with the dynamic laser cruise control —
When the cruise control is being used in the conventional
(fixed speed) cruise control mode or in the
vehicle −to−vehicle distance control mode, even if you
downshift from “D” or “5” (fifth range) to “4” (fourth range),
engine braking will not be enabled because the cruise
control is not cancelled. For vehicle speed reduction, see
pages 427 and 436.
 Shift into the “3” (third range) position. The transmission will
downshift to third gear when the vehicle speed is or
becomes lower than 129 km/h (81 mph) and more powerful
engine braking will be enabled.
If you drive in the “D” position: Shift the selector lever to
the “S” position then shift the lever down to the “ −” position
once to select the “3” (third range).
If you drive in the “S” position: Shift the selector lever
down to the “ −” position to select “3” (third range).

Check surroundings for safety.
If a bright light (for example, sunlight reflected off the vehicle
body) is picked up by the camera, the smear effect* peculiar to
the camera may occur.
*: Smear effect — A phenomenon that occurs when a bright
light (for example, sunlight reflected off the vehicle body) is
picked up by the camera; when transmitted by the camera, the
light source appears to have a vertical streak above and below
it.
CRUISE CONTROL
The cruise control 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
40 km/h (25 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
 To help maintain maximum control of your vehicle,
do not use the cruise control when driving in heavy
or varying traffic, or on slippery (rainy, icy or
snowcovered) or winding roads.
 Avoid vehicle speed increases when driving
downhill. If the vehicle speed is too fast in relation to
the cruise control set speed, cancel the cruise
control then downshift the transmission to use
engine braking to slow down.

STARTING AND DRIVING
413
(a) Turning the system on and off
To turn the cruise control on, press the “ON−OFF” button. The
“CRUISE” indicator light in the instrument cluster will come on
to indicate that the cruise control is operational. Pressing the
“ON−OFF” button again turns the system off.
When the system is turned off, cruising speed must be reset
when the cruise control is turned on again.
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.
(b) Setting operation
 Each function is described below.
1Setting 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.
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.

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.

415
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.
