The “START STOP ENGINE” <“POWER”> switch is in ACCESSORY or IGNI-
TION ON mode
*.
*: If the driver’s seat belt is fastened, the steering wheel can be adjusted regardless of“START STOP ENGINE” <“POWER”> switch mode.
■Automatic adjustment of the steering position (power adjustment type)
A desired steering position can be entered to memory and recalled automatically by
the driving position memory system. ( →P. 1 5 3 )
■Power easy access system (power adjustment type)
The steering wheel and driver’s seat move in accordance with “START STOP
ENGINE” <“POWER”> switch mode and the driver’s seat belt condition. ( →P. 1 5 6 )

CAUTION
■If you hear a squealing or scraping noise (brake pad wear limit indicators)
Have the brake pads checked and replaced by your Lexus dealer as soon as possi-
ble.
Rotor damage may result if the pads are not replaced when needed.
It is dangerous to drive the vehicle when the wear limits of the brake pads and/or
those of the brake discs are exceeded.
■When the vehicle is stopped
●Gasoline vehicles: Do not race the engine.
If the vehicle is in any gear other than P or N, the vehicle may accelerate suddenly
and unexpectedly, causing an accident.
Hybrid vehicles: Do not depress the accelerator pedal unnecessarily.
If the vehicle is in any gear other than P or N, the vehicle may accelerate suddenly
and unexpectedly, causing an accident.
●In order to prevent accidents due to the vehicle rolling away, always keep
depressing the brake pedal while the engine is running on>, and apply the parking brake as necessary.
●If the vehicle is stopped on an incline, in order to prevent accidents caused by the
vehicle rolling forward or backward, always depress the brake pedal and securely
apply the parking brake as needed.
●Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped may cause the
exhaust system to overheat, which could result in a fire if combustible material is
nearby.

CAUTION
■When taking a nap in the vehicle
Always turn the engine off. Otherwise, if you accidentally move
the shift lever or depress the accelerator pedal, this could cause an accident or fire
due to engine overheating. Additionally, if the vehicle is parked in a
poorly ventilated area, exhaust gases may collect and enter the vehicle, leading to
death or a serious health hazard.
■When braking
●When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause one side
of the vehicle to brake differently than the other side. Also, the parking brake may
not securely hold the vehicle.
●If the brake booster (gasoline vehicles) or brake actuator (hybrid vehicles) does
not operate, do not follow other vehicles closely and avoid hills or sharp turns that
require braking.
In this case, braking is still possible, but the brake pedal should be depressed
more firmly than usual. Also, the braking distance will increase.
●Gasoline vehicles only: Do not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses up the reserve for the power-assisted brakes.
●Gasoline vehicles: The brake system consists of 2 individual hydraulic systems; if
one of the systems fails, the other will still operate. In this case, the brake pedal
should be depressed more firmly than usual and the braking distance will
increase. If this happens, do not drive the vehicle. Have your brakes fixed immedi-
ately.
Hybrid vehicles: The brake system consists of 3 individual hydraulic systems; if
one of the systems fails, the others will still operate. In this case, the brake pedal
should be depressed more firmly than usual and the braking distance will
increase. If this happens, do not continue to drive the vehicle. If the brake system
warning light (red indicator) comes on together with the buzzer sound while driv-
ing, immediately stop the vehicle in a safe place and contact your Lexus dealer.

CAUTION
■Things that must not be carried in the trunk
The following things may cause a fire if loaded in the trunk:
●Receptacles containing gasoline
●Aerosol cans
■Storage precautions
Observe the following precautions.
Failure to do so may prevent the pedals from being depressed properly, may block
the driver’s vision, or may result in items hitting the driver or passengers, possibly
causing an accident.
●Stow cargo and luggage in the trunk whenever possible.
●Do not place cargo or luggage in or on the following locations.
• At the feet of the driver
• On the front passenger or rear seats (when stacking items)
• On the package tray
• On the instrument panel
• On the dashboard
• In front of the navigation system screen, Lexus Display Audio system screen or the audio/air conditioning system display
●Secure all items in the occupant compartment.
■Capacity and distribution
●Do not exceed the maximum axle weight rating or the total vehicle weight rating.
●Even if the total load of occupant’s weight and the cargo load is less than the total
load capacity, do not apply the load unevenly. Improper loading may cause dete-
rioration of steering or braking control which may cause death or serious injury.
