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 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 any person or object that is statically
charged.
This may cause static electricity to build up, resulting in a possible ignition hazard.

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

■When replacing the fuel cap
Do not use anything but a genuine Lexus fuel tank cap designed for your vehicle.
Doing so may cause a fire or other incident which may result in death or serious
injury.
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 system components or the vehicle's painted
surface.

Trailer towing (RX350)
The strain of towing a trailer will have a negative impact on the running per-
formance, handling, fuel consumption and endurance of your vehicle. Use
the vehicle features in the correct manner and operate the vehicle with
care for safer driving and optimal comfort. Damage and/or malfunctions
that occur as a result of towing performed for commercial purposes are
not covered by the Lexus warranty.
Ask your local authorized Lexus dealer or repairer, or another duly quali-
fied and equipped professional for further details before towing, as there
are additional legal requirements in some countries.
■Weight limits
Check the allowable towing capacity, GVM (Gross Vehicle Mass),
MPAC (Maximum Permissible Axle Capacity), and permissible
drawbar load before towing. (→P. 606)
■Towing hitch/bracket
Lexus recommends the use of the Lexus hitch/bracket for your
vehicle. Other products of a suitable nature and comparable quality
may also be used.
■To prevent an accident
The handling of the vehicle will feel different when towing a trailer.
Beware of the 3 most common causes of towing-related accidents:
driver error, excessive speed, and overloading.
