2006 LEXUS RX330 stop start

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
438This electronically modulated air suspension allows the
driver to
control the vehicle’s height in order to adjust for
driving conditions. Select your desired height among the
“HI” (high), “N” (normal) and “LO” (low) modes with the
height select switch.
You can turn on or off the easy access mode with the easy
access mode switch. If the engine is stopped when the easy
access mode is on, the vehicle height is lowered automatically.

“N” (normal) mode
“N” (normal) mode: The vehicle’s height in this mode is
standard.
This mode is suitable for ordinary driving.
When the vehicle speed exceeds approximately 100 km/h (62
mph), the vehicle’s height automatically lowers about 7 mm
(0.3 in.) from normal height to provide better stability. When the
vehicle speed reduces to under approximately 80 km/h (50
mph), the vehicle’s height automatically returns to the normal
height.

 Easy access mode
Easy access mode: The vehicle’s height is about 30 mm (1.2
in.) lower than the normal height.
This mode allows easy access to the vehicle (getting in and
out) and easy loading and unloading operations.
This mode is available when “N” or “LO” mode is selected.
When the engine is stopped, easy access mode is
automatically selected, and the height adjusted.

STARTING AND DRIVING
441
In the following cases, vehicle height is changed to “N”
(normal) mode height automatically.

Vehicle speed exceeds approximately 12 km/h (8 mph).
 The engine is restarted and the easy access mode is
canceled.
CAUTION
When the engine is stopped in easy access mode,
vehicle height is changed quickly. Be careful not to
get your head, hands or other parts of your body
caught by the lowering underbody of the vehicle.
 You must also make sure nobody places his or her
head, hands or other parts of their body between the
body of the vehicle and tires.
NOTICE
Be careful when you drive in any place where overhead
space is limited and you have selected the easy access
mode. When the vehicle begins to move after stopping,
“N” (normal) mode will automatically be selected,
raising the vehicle’s height, and potentially causing
damage to the vehicle.
(b) Automatic leveling function
Regardless of the number of occupants or the luggage
load, vehicle height in any mode is always adjusted
automatically to a fixed height.
(c) Selecting “LO”, “HI” or “N” mode
Selection conditions: To select the vehicle’s height, it is
necessary to meet the following conditions.
 The engine is running.
 The height control “OFF” indicator light is off.
 The vehicle is within the speed limitations. Refer to the

leveling function may cause the vehicle’s height to
change, resulting in an unexpected accident.
 If your vehicle must be towed, put the vehicle height
in the “N” mode and turn off the electronically
modulated air suspension. Otherwise, the automatic
leveling function may cause the vehicle’s height to
change, resulting in an unexpected accident.
