2006 LEXUS RX330 instrument cluster

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.

(l) Vehicletovehicle distance control mode failure
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.

(g) Conventional cruise control mode failure warning
If there is trouble in the conventional cruise control mode, the
“CRUISE” indicator light in the instrument cluster flashes, the
master warning light comes on and the alarm sounds, the
warning code “E3” will appear on the display.
If a system malfunction is detected when the conventional
cruise control mode is in the ready mode or operating, the
master warning light comes on, an alarm sounds and the
above code appears.
If this code appears, press 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 code appears again, the system
might have malfunctioned. Although there is no problem to
continue driving, please contact your Lexus dealer.

Quality gasoline
Automotive manufacturers in the U.S., Europe and Japan
have developed a specification for quality fuel named
WorldWide Fuel Charter (WWFC) that is expected to be
applied world wide. The WWFC consists of four
categories that depend on requi red emission levels. In the
U.S., category 4 has been adopted. The WWFC improves
air quality by providing for better emissions in vehicle
fleets, and customer satisfaction through better vehicle
performance.
Cleaner burning gasoline
Cleaner burning gasoline, including reformulated
gasoline that contains oxygenates such as ethanol or
MTBE is available in many areas.
Lexus recommends the use of cleaner burning gasoline and
appropriately blended reformulated gasoline. These types of
gasoline provide excellent vehicle performance, reduce
vehicle emissions, and improve air quality.
Oxygenates in gasoline
Lexus allows the use of oxygenate blended gasoline
where the oxygenate content is up to 10% ethanol or 15%
MTBE. If you use gasohol in your Lexus, be sure that it has
an octane rating no lower than 91.
Lexus does not recommend the use of gasoline containing
methanol.
Gasoline containing MMT
Some gasoline contain an octane enhancing additive
called MMT (Methylcyclopentadienyl Manganese
Tricarbonyl).
Lexus does not recommend the use of gasoline that contains
MMT. If fuel containing MMT is used, your emission control
system may be adversely affected. The Malfunction Indicator
Lamp on the instrument cluster may come on. If this happens,
contact your Lexus dealer for service.
