2006 LEXUS RX330 Owners Manual

STARTING AND DRIVING
436To turn the system off, push the “ON
−OFF” button. Make sure
the “CRUISE” indicator light is off.
If the conventional cruise control mode automatically cancels
out other than for the above cases, have your vehicle checked
by your Lexus dealer at the earliest opportunity.
(d) Resuming the conventional cruise control mode
If the conventional cruise control mode 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).
(e) Resetting to a faster speed
Push the lever up in the “+ RES” direction and hold it. Release
the lever when the desired speed is attained. While the lever
is held up, 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 pushing the lever up
in the “+ RES” direction quickly within 0.6 seconds.
However, a faster way to reset is to accelerate the vehicle and
then push the lever down in the “ − SET” direction. (f) Resetting to a slower speed
Push the lever down in the “
− SET” direction and hold it.
Release the lever when the desired speed is attained. While
the lever is held down, 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 pushing the lever down
in the “− SET” direction quickly within 0.6 seconds.
However, a faster way to reset is to accelerate the vehicle and
then push the lever down in the “ − SET” direction.
With automatic transmission (standard type) —
Even if you downshift from “D” to “4” in the conventional cruise
control mode, engine braking will not be enabled because this
mode is not cancelled. To decrease the vehicle’s 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 from “D” or “5” (fifth range) to “4” (fourth
range) in the conventional cruise control mode, engine braking
will not be enabled because this mode is not cancelled. To
decrease the vehicle’s 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.

(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

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.
ELECTRONICALLY MODULATED AIR SUSPENSION

2Height control switch
3Height select switch

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.

 “HI” (high) mode
“HI” (high) mode: The vehicle’s height is about 30 mm (1.2
in.) higher than the normal height.
This mode is suitable for driving on bumpy roads.
When the vehicle speed exceeds approximately 50 km/h (31
mph) or driving at the speeds of 30 km/h (19 mph) or over for
ten seconds total in “HI” mode, “N” mode is automatically
selected. Even if the vehicle speed then reduces to under 50
km/h (31 mph), the vehicle’s height will not return to “HI” mode.
CAUTION
The “HI” mode should be used for severe offroad
driving conditions only. As the vehicle’s center of
gravity is higher in this setting, the vehicle may become
unstable when turning abruptly, resulting in an
unexpected accident.

When the engine is turned off and then restarted, the “N”
(normal) mode will automatically be selected.

 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
following table.

STARTING AND DRIVING
442In the following cases, the electronically modulated air
suspension will not operate.

The underbody of the vehicle has touched the surface of the
road.
 The area around the suspension is covered with ice.
The indicator lights change as follows when the
electronically modulated air suspension will not operate.
1. The current mode indicator light goes off and the currently
selected mode indicator light blinks.
2. The selected mode indicator light goes off. (The vehicle
height does not change.) The selected mode indicator light
comes on again.
The vehicle’s electronically modulated air suspension will not
be operable even if the vehicle is moved to a smooth road or
the ice is removed. To operate electronically modulated air
suspension, turn off the engine and then restart it. The
electronically modulated air suspension will operate again.

Even if the engine stops while the vehicle’s height is being
lowered, the operation continues for up to one minute.
CAUTION
 Before you lower the vehicle’s height with the height
select switch, check under the vehicle to make sure
nothing that could damage the vehicle or no one who
could be injured is there and that the underbody of
the vehicle does not touch the ground.
 Do not select the “HI” mode when you load cargo on
the roof luggage carrier. Otherwise it may result in a
loss of control or vehicle rollover due to failure to
operate this vehicle correctly.
NOTICE
If the vehicle height is changed frequently, the
compressor may overheat, causing the vehicle
height adjustment operation to stop.
 After unloading, vehicle height rises slightly. Take
sufficient care where overhead space is restricted.
 Do not select “LO” mode when on bumpy roads. If
the underbody of the vehicle touches the rugged
road surface, the vehicle may be damaged.
