Do not perform circling calibration of the compass in a place
where the earth’s magnetic field is subject to interference by
artificial magnetic fields (underground parking, under a
steel tower, between buildings, roof parking, near a
crossing, near a large vehicle, etc.).
 During calibration, do not operate electric systems (moon
roof, power windows, etc.) as they may interfere with the
calibration.
CAUTION
When doing the circling calibration, be sure to secure
a wide space, and watch out for people and vehicles
in the neighborhood. Do not violate any local traffic
rules while performing circling calibration.
 Do not adjust the display while the vehicle is moving.
Be sure to adjust the display only when the vehicle is
stopped.

OCCUPANT RESTRAINT SYSTEMS
155
If your steering wheel is adjustable, tilt it downward.
This points the airbag toward your chest instead of
your head and neck.
The seat should be adjusted as recommended by
NHTSA above, while still maintaining control of the foot
pedals, steering wheel, and your view of the instrument
panel controls.
Front passenger seat
CAUTION
The SRS front passenger airbag also deploys with
considerable force, and can cause death or serious
injury especially if the front passenger is very close to
the airbag. The front passenger seat should be as far
from the airbag as possible with the seatback adjusted,
so the front passenger sits upright.
Front seats
CAUTION
The SRS side airbags are installed in the driver and front
passenger seats. Observe the following precautions.
 Do not lean against the front door when the vehicle
is in use, since the side airbag inflates with
considerable speed and force. Otherwise, you may
be killed or severely injured.
 Do not use seat accessories which cover the area
where the side airbags inflate. Such accessories may
prevent the side airbags from activating correctly,
causing death or serious injury.
 Do not modify or replace the seats or the upholstery
of the seats equipped with side airbags. Such
change may prevent the side airbag system from
activating correctly, disable the system, or cause the
side a irbags to inflate accidentally, resulting in death
or serious injury.

STARTING AND DRIVING
310“4” (fourth range):
The most suitable gear is automatically
selected between first and fourth gears according to vehicle
speed and driving conditions. In the “4” (fourth range)
position, the automatic transmission system will select the
most suitable gear to handle current running conditions
such as hill climbing, hard towing, etc.
“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 59 (36)
2 100 (62)
3 146 (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.

STARTING AND DRIVING

3“P” (Park) position
1. Bring the vehicle to a complete stop.
2. Depress the parking brake pedal fully to securely apply the
parking brake.
3. With the brake pedal held down with your foot, shift the
selector lever to the “P” position.
CAUTION
Never attempt to move the selector lever into “P” under
any circumstances while the vehicle is moving. Serious
mechanical damage and loss of vehicle control may
result.
(f) Good driving practice
 If the transmission repeatedly shifts up and down between
fourth and overdrive gears when climbing a gentle slope,
shift the selector lever to the “4” position. Be sure to shift the
selector lever to the “D” position after climbing the slope.
 When towing a trailer, in order to maintain efficient engine
braking and electrical charging performance, do not use
overdrive. The selector lever must be in the “4” position.
CAUTION
Always keep your foot on the brake pedal while stopped
with the engine running. This prevents the vehicle from
creeping.
NOTICE
Always use the brake pedal or the parking brake to hold
the vehicle on an upgrade. Do not attempt to hold the
vehicle using the accelerator pedal, as this can cause
the transmission to overheat.

STARTING AND DRIVING
322The Lexus park assist system may detect the following by
mistake:

Bumpy roads or gravelled roads or grass when driving on
such surfaces, or on grass

another vehicle, motorcycle engine, air braking sound from
heavy−duty vehicles, if such a device is operated around
your vehicle
 Rain or water splashing over the sensor
 The ground on which the vehicle is tilted
 Radio antenna or fender pole mounted on your vehicle
 Mud, ice or snowflakes on the sensor
 Tall curb stone
 Towing eyelet mounted on your vehicle
 Towing hitch mounted on your vehicle The Lexus park assist system may not detect the
following:

Thin objects such as wire or rope
 Objects with a surface area too small to reflect ultrasonic
waves such as wire gauze or fence
 Sound wave absorbing objects such as cotton or snow
 Objects with a sharp edge
 Shorter objects
 Tall objects with the upper part projected
For vehicles with a Navigation System, the park assist
graphics appear both on the navigation display and
multi− information display. For details, see the separate

STARTING AND DRIVING
341
After bringing 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. At this time, the
multi−information display indicates settings such as the preset
vehicle speed, whether a vehicle is present ahead and
selected vehicle −to−vehicle distance. If there is no vehicle
detected ahead, the dynamic radar/laser cruise control screen
does not display the vehicle ahead. At this time, you may 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 warning tone sounds and the multi− information
display indicates a warning me ssage such as “Cruise not
Available”, “Clean Radar Sensor” or “Check Cruise System”.
If any of the above messages appears on the display, see
“Vehicle −to−vehicle distance control mode failure warning” on
page 352.
If you turn off the “ON−OFF” button while the warning message
is displayed, the warning message turns off and the
multi−information display switches to another screen. If no
warning message appears on the display, when you turn the
“ON−OFF” button on again, the setting can be made.
You can change the dynamic radar/laser cruise control screen
to another screen even while the warning message is
displayed.
2 Cancelling the preset speed
You can cancel the preset speed by doing any of the following:
a. Pulling the control lever toward you, in the ”CANCEL”
direction.
b. Depressing the brake pedal.
c. Pushing the “ON −OFF” button at the end of the cruise
control lever.
If cancelled by a. or b., the multi−information display shows
“RADAR READY” and the dynamic radar/laser cruise control
enters the ready mode.
If cancelled by c., the “CRUISE” indicator light goes off in the
instrument panel and the multi −information display shows
“CRUISE OFF”. In this case, the preset speed data is cleared,
and you must set the speed from the beginning.
