1-3. Adjustable components
■Canceling the linked door unlock operation
Turn the engine switch OFF and close the driver's door.
While pushing the SET button, push the or button on the
wireless remote control until the signal beeps.
■Retained accessory power
Memorized positions (except for the steering wheel positions) can be activated up
to 30 seconds after the driver's door is opened, even after turning the engine
switch OFF.
■To cancel seat position recall
Perform any of the following operations.
●Push the SET button.
●Push button 1, 2, or 3.
●Adjust the seat using the switches (only cancels seat position recall).
■If the battery is disconnected
The memorized positions are erased when the battery is disconnected.
CAUTION
■Seat adjustment caution
Take care during seat adjustment that the seat does not strike the rear passenger or
squeeze your body against the steering wheel.

1-3. Adjustable components
Before driving
Steering wheel (power-adjustable type)
Auto tilt away
When the engine switch is turned
OFF, the steering wheel returns to
its stowed position by moving up
and away to enable easier driver
entry and exit.
Switching to ACC or IG-ON
mode will return the steering wheel
to the original position.
The steering wheel can be adjusted to a comfortable position while the
engine switch is in ACC or IG-ON mode.

Down
Away from the driver
Toward the driver
CAUTION
■Caution while driving
Do not adjust the steering wheel while driving.
Doing so may cause the driver to mishandle the vehicle and an accident, resulting in
death or serious injury.

1-7. Safety information
1
Before driving
In certain types of severe frontal or side impacts, the SRS airbag system
triggers the airbag inflators. A chemical reaction in the inflators quickly
fills the airbags with non-toxic gas to help restrain the motion of the occu-
pants.
■SRS warning light
This warning light system monitors the airbag sensor assembly, front airbag sensors,
side and curtain shield airbag sensor assemblies, curtain shield airbag sensor
assemblies, driver's seat position sensor, driver's seat belt buckle switch, seat belt
pretensioner assemblies, inflators, interconnecting wiring and power sources.
(P. 3 4 0 )
■If the SRS airbags deploy (inflate)
●Bruising and slight abrasions may result from contact with a deploying (inflating)
SRS airbag.
●A loud noise and white powder will be emitted.
●Parts of the airbag module (steering wheel hub, airbag cover and inflator) as
well as the front seats, and parts of the front pillar, rear pillar and roof side rail,
may be hot for several minutes. The airbag itself may also be hot.
●The front windshield may crack.
■Operating conditions (front airbags)
●The SRS front airbags will deploy if the severity of the frontal impact is above the
designed threshold level, comparable to an approximate 15 mph (25 km/h) col-
lision when the vehicle impacts straight into a fixed barrier that does not move
or deform.
However, this threshold velocity will be considerably higher if the vehicle strikes
an object, such as a parked vehicle or sign pole, which can move or deform on
impact, or if the vehicle is involved in an underride collision (e.g. a collision in
which the front of the vehicle "underrides", or goes under, the bed of a truck, etc.).
●It is possible that in some collisions where the forward deceleration of the vehi-
cle is very close to the designed threshold level, the SRS front airbags and the
seat belt pretensioners may not activate together.
●The SRS front passenger airbag will not activate if there is no passenger sitting
in the front passenger seat. However, the front passenger airbag may deploy if
luggage is put in the seat, or the seat belt is fastened, even if the seat is unoccu-
pied. (P. 7 2 )

2-1. Driving procedures
NOTICE
■When driving the vehicle
●With manual transmission vehicles, do not rest your foot on the clutch pedal while
driving.
Doing so may cause clutch trouble.
●With manual transmission vehicles, do not use any gears other than the first gear
when starting off and moving forward.
Doing so may damage the clutch.
●With automatic transmission vehicles, do not use the accelerator pedal or
depress accelerator and brake pedals together to hold the vehicle on a hill.
●With manual transmission vehicles, do not use the clutch to hold the vehicle when
stopping on an uphill grade.
■When parking the vehicle
With automatic transmission vehicles, always put the shift lever in P. Failure to do so
may cause the vehicle to move or the vehicle may accelerate suddenly if the accel-
erator pedal is accidentally depressed.
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for a long
time.
Doing so may damage the power steering motor.
●When driving over bumps in the road, drive as slowly as possible to avoid damag-
ing the wheels, underside of the vehicle, etc.

When driving
NOTICE
■If you hear a squealing or scraping noise (brake pad wear limit indicators)
Have your Lexus dealer check and replace the brake pads as soon as possible.
The rotor damage can result if the pads are not replaced when needed.
Front brake only: Moderate levels of the brake pad and disc wear allow enhanced
front braking power. As a result, the discs may wear more quickly than conventional
brake discs. Therefore, when replacing the brake pads, Lexus recommends that you
also have the thickness of the discs measured.
It is dangerous to drive the vehicle when the wear limits of the brake pads and/or
that of the brake discs are exceeded.
■If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering wheel
firmly and gradually press the brake pedal to slow down the vehicle.
●It may be difficult to control your vehicle.
●The vehicle will make abnormal sounds.
●The vehicle will behave abnormally.
Replace a flat tire with a new one. (P. 360)

2-4. Using other driving systems
Driving assist systems
To help enhance driving safety and performance, the following systems
operate automatically in response to various driving situations. Be aware,
however, that these systems are supplementary and should not be relied
upon too heavily when operating the vehicle.
■ABS (Anti-lock Brake System)
Restrains the vehicle from slipping when driving on slick road surfaces or
in the event of sudden braking.
■BA (Brake Assist)
Generates an increased level of braking force after the brake pedal is
depressed, when the system detects a panic stop situation.
■VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning on
slippery road surfaces.
■TRAC (Traction Control)
Maintains drive power and prevents the rear wheels (2WD models) or all
wheels (4WD models) from spinning when starting the vehicle or acceler-
ating on slippery roads.
■Hill-start assist control (vehicles with an automatic transmission)
Prevents the vehicle from rolling backwards when starting on an incline or
slippery slope.
■EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel.
