■Canceling the linked door unlock operation
Close the driver’s door with the “ENGINE START STOP” switch set to
the OFF.
Push the “SET” button and the button on the wireless remote control
at the same time for about 1 second until you hear 2 beeps.
■Retained accessory power
With front passenger’s seat memory
●Each memorized position (except for the tilt and telescopic steering column)
can be recalled within 3 minutes after the corresponding side door is opened,
even if the “ENGINE START STOP” switch is turned to OFF.
●Driver’s side: Each memorized position (except for the tilt and telescopic steer-
ing column) can be recalled within 60 seconds after the driver’s door is closed,
even if the “ENGINE START STOP” switch is turned to OFF.
Without front passenger’s seat memory
●Each memorized position (except for the tilt and telescopic steering column)
can be recalled within 3 minutes after the driver’s door is opened, even if the
“ENGINE START STOP” switch is turned to OFF.
●Each memorized position (except for the tilt and telescopic steering column)
can be recalled within 60 seconds after the driver’s door is closed, even if the
“ENGINE START STOP” switch is turned to OFF.
■If any position memory button is pushed while the adjustments are being made
The operation will stop. To reactivate the system, push the desired button (“1”, “2” or
“3”) again.
■If the 12 volt battery is disconnected
The memorized positions must be reset because the computer’s memory is erased
when the 12 volt battery is disconnected.

Your vehicle is equipped with “ADVANCED AIRBAGS” designed based
on US motor vehicle safety standards (FMVSS208). The airbag system
controls airbag deployment power for the driver and front passenger. The
driver airbag system consists of the driver’s seat position sensor etc. The
front passenger’s airbag system consists of the front passenger occupant
classification sensor etc.
The main SRS airbag system components are shown above. The SRS air-
bag system is controlled by the airbag sensor assembly. The airbag sen-
sor assembly consists of a safing sensor and an airbag sensor.
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.
■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 seats, and parts of the front pillar and roof side rail, may be hot for
several minutes. The airbag itself may also be hot.
●The windshield may crack.
●For vehicles with Safety Connect: For Safety Connect subscribers, if the SRS
airbags deploy or in the event of a severe collision, the system is designed to
send an emergency call to the response center, notifying them of the vehicle’s
location (without needing to push the “SOS” button) and an agent will attempt
to speak with the occupants to ascertain the level of emergency and assistance
required. If the occupants are unable to communicate, the agent automatically
treats the call as an emergency and helps to dispatch the necessary emergency
services. (P. 4 2 1 )

CAUTION
■When driving the vehicle
●Do not shift the shift lever to "D" while the vehicle is moving backward.
Doing so can damage the transmission and may result in a loss of vehicle control.
●Moving the shift lever to "N" while the vehicle is moving will disengage the engine
from the transmission. Engine braking is not available when "N" is selected.
●During normal driving, do not turn off the engine. Turning the engine off while
driving will not cause loss of steering or braking control, but the power assist to
these systems will be lost. This will make it more difficult to steer and brake, so you
should pull over and stop the vehicle as soon as it is safe to do so.
However, in the event of an emergency, such as if it becomes impossible to stop
the vehicle in the normal way: P. 5 3 4
●Use engine braking (downshift) to maintain a safe speed when driving down a
steep hill. 
Using the brakes continuously may cause the brakes to overheat and lose effec-
tiveness. (P. 141)
●When stopped on an inclined surface, use the brake pedal and parking brake to
prevent the vehicle from rolling backward or forward and causing an accident.
●Be careful when driving on slippery surfaces, as the vehicle may spin or skid when
downshifting, rapidly accelerating, braking or turning.
●Do not adjust the position of the steering wheel, the seat, or the inside or outside
rear view mirrors while driving.
Doing so may result in a loss of vehicle control that can cause accidents that may
result in death or serious injury.
●Always check that all passengers’ arms, heads or other parts of their bodies are
not outside the vehicle, as this may result in death or serious injury.
●Do not drive in excess of the speed limit. Even if the legal speed limit permits it, do
not drive over 85 mph (140 km/h) unless your vehicle has high-speed capability
tires. Driving over 85 mph (140 km/h) may result in tire failure, loss of control and
possible injury. Be sure to consult a tire dealer to determine whether the tires on
your vehicle are high-speed capability tires or not before driving at such speeds.

NOTICE
■While driving the vehicle
Do not use the accelerator pedal or depress accelerator and brake pedals together
to hold the vehicle on a hill.
■When parking the vehicle
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 accelerator 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.
■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 the engine does not start
The immobilizer system may not have been deactivated. (P. 8 5 )
■When the steering lock cannot be released
■When the “ENGINE START STOP” switch indicator flashes in amber
The system may be malfunctioning. Have the vehicle inspected by your Lexus
dealer immediately.
■Auto power OFF function
If the vehicle is left in ACCESSORY or IGNITION ON mode (the engine is not
running) for more than an hour with the shift lever in P, the “ENGINE START STOP”
switch will automatically turn off. However, this function cannot entirely prevent bat-
tery discharge. Do not leave the vehicle with the “ENGINE START STOP” switch in
ACCESSORY or IGNITION ON mode for long periods of time when the engine
is not running.
■Electronic key battery depletion
P. 3 5
■When the electronic key battery is discharged

■Conditions affecting operation
P. 3 3
The green indicator light on the “ENGINE
START STOP” switch will flash and a mes-
sage will be shown on the multi-information
display. Press the “ENGINE START STOP”
switch again while turning the steering wheel
left and right.
