Wearing a seat belt ●
Ensure that all passengers wear a seat belt.●
Always wear a seat belt properly.●
Each seat belt should be used by one person only. Do not use a seat belt for more
than one person at on ce, including children.●
Lexus recommends that children be seated in the rear seat and always use a seat
belt and/or an appropriate child restraint system.●
To achieve a proper seating position, do not recline the seat more than necessary.
The seat belt is most effective when the occupants are sitting up straight and well
back in the seats.●
Do not wear the shoulder belt under your arm.●
Always wear your seat belt low and snug across your hips. If your seat belts cann ot be fastened securely
because they are not long enough, a person-

Before driving CAUTION■
Using a seat belt extender ●
Do not wear the seat belt extender if you can fasten the seat belt without the
extender.●
Do not use the seat belt extender when installing a child restraint system because
the belt will not securely hold the child restraint system, increasing the risk of
death or serious injury in the event of an accident.●
The personalized extender may not be safe on another vehicle, when used by
another person, or at a different seatin g position other than the one originally
intended.
NOTICE■

not on the seat belt.

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 re moving the cap. In hot weather, pressur-
ized fuel may spray out of 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 an y 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
■
When replacing the fuel cap
Do not use anything but a genuine Lexus fuel tank cap designed for your vehicle.
