2006 LEXUS RX330 warning

OCCUPANT RESTRAINT SYSTEMS
197
If an adult sits in the front passenger seat, the
“AIRBAG ON” indicator light is illuminated. If the
“AIRBAG OFF” indicator is illuminated, ask the
passenger to sit up straight, well back in the seat, feet
on the floor, and with the seat belt worn correctly. If
the “AIRBAG OFF” indicator still remain illuminated,
either ask the passenger to move to the rear seat, or
if that is not possible, move the front passenger seat
fully rearward.
 When it is unavoidable to install the forwardfacing
child restraint system on the front passenger seat,
install the child restraint system on the front
passenger seat in the proper order. (As for the
installation order, see “Child restraint system” on
page 199.)
 Do not remove the seat.
 Do not kick the front passenger seat or subject it to
severe impact. Otherwise, the SRS warning light may
come on to indicate a malfunction of the detection
system. In this case, contact your Lexus dealer
immediately.
 Child restraint systems installed on the rear seat
should not contact the front seatbacks.In addition to the precautions outlined above, the “AIRBAG
ON” indicator light may be illuminated when a child sits in the
front passenger seat or a forward −facing child restraint system
is installed in the front passenger seat. If the “AIRBAG ON”
indicator light is illuminated in these circumstances, the front
passenger airbag and side airbag on the front passenger side
are in an activated condition — the airbags will deploy if an
impact meets the deployment criteria. Refer to all the cautions
in this Section and “Child restraint system” on page 199.

STARTING AND DRIVING
402“3” (third range): The most suitable gear is automatically
selected between first and third gears according to vehicle
speed and driving conditions. This range is best used when
stronger engine braking is necessary.
“2” (second range): First or second gear will automatically
be selected according to vehicle speed and driving
conditions. This range is to be used when engine braking
stronger than that of the “3” (third range) position is
necessary.
“1” (first range): This gear is fixed in first regardless of
vehicle
speed or driving conditions. This range is to be used
when maximum engine braking is necessary.
If you attempt to downshift the transmission when it is not
possible to downshift due to high vehicle speed, a warning tone
sounds twice. 
Maximum allowable speeds
To get on a highway or to pass slower traffic, maximum
acceleration may be necessary. Make sure you observe the
following maximum allowable speeds in each range:
range km/h (mph)1 51 (32)
2 92 (58)
3 144 (90)
NOTICE
Do not downshift if you are going faster than the
maximum allowable speed for the next lower range.
 “S” mode indicator light
“S” mode allows you to use the shift range positions.
The “S” mode indicator light comes on when the selector
lever is shifted into the “S” position. When the “S” mode
indicator light does not come on even with the selector lever
moved to the “S” position, there may be a problem
somewhere in the system. Have your vehicle
checked/repaired by your Lexus dealer as soon as possible.
In this case, you can drive in the same condition as in the “D”
position.

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.

DYNAMIC LASER CRUISECONTROL
Dynamic laser cruise control allows you to drive at a
constant cruising speeds over about 45 km/h (28 mph)
with your foot off the accelerator pedal, maintaining an
appropriate vehicletovehicle distance between the
vehicle ahead.
CAUTION
Do not rely excessively on dynamic laser cruise control
in order to avoid serious injury or death, or to prevent
accidents or to control the vehicle’s speed in
emergency situations. Do not use cruise control except
in appropriate road and traffic conditions. Always drive
carefully and attentively. Before using dynamic laser
cruise control, read and understand the following
instructions.1Cruise control switch

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
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.
