4-1. Before driving
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 <the “READY” indicator is
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 whil e the vehicle is stopped may cause the
exhaust system to overheat, which could result in a fire if combustible material is
nearby.

4-1. Before driving
CAUTION
■When taking a nap in the vehicle
Always turn the engine <hybrid system> off. Otherwise, if you accidentally move
the shift lever or depress the accelerator pedal, this could cause an accident or fire
due to engine <hybrid system> 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 st ill 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 st ill 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.

Driving
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.

4-2. Driving procedures
■Auto power off function
If the vehicle is left in ACCESSORY mode for more than 20 minutes or IGNITION
ON mode (the engine is not running) for more than an hour with the shift lever in P,
the “START STOP ENGINE” switch will automatically turn off. However, this func-
tion cannot entirely prevent 12-volt batter y discharge. Do not leave the vehicle with
the “START STOP ENGINE” switch in ACCESSORY or IGNITION ON mode for
long periods of time when the engine is not running.

4-4. Refueling
CAUTION
■When refueling the vehicle
Observe the following precautions while refueling the vehicle. Failure to do so may
result in death or serious injury.
●After exiting the vehicle and before opening the fuel door, touch an unpainted
metal surface to discharge any static electricity. It is important to discharge static
electricity before refueling because sparks resulting from static electricity can
cause fuel vapors to ignite while refueling.
●Always hold the grips on the fuel tank cap and turn it slowly to remove it.
A whooshing sound may be heard when the fuel tank cap is loosened. Wait until
the sound cannot be heard before fully removing the cap. In hot weather, pressur-
ized fuel may spray out the filler neck and cause injury.
●Do not allow anyone that has not discharged static electricity from their body to
come close to an open fuel tank.
●Do not inhale vaporized fuel.
Fuel contains substances that are harmful if inhaled.
●Do not smoke while refueling the vehicle.
Doing so may cause the fuel to ignite and cause a fire.
●Do not return to the vehicle or touch any person or object that is statically
charged.
This may cause static electricity to build up, resulting in a possible ignition hazard.
■When refueling
Observe the following precautions to prevent fuel overflowing from the fuel tank:
●Securely insert the fuel nozzle into the fuel filler neck.
●Stop filling the tank after the fuel nozzle automatically clicks off.
●Do not top off the fuel tank.
NOTICE
■Refueling
Do not spill fuel during refueling.
Doing so may damage the vehicle, such as causing the emission control system to
operate abnormally or damaging fuel syst em components or the vehicle’s painted
surface.
