CAUTION
Refueling the vehicle
Observe the following precautions while refueling the vehicle.
Failure to do so may result in death or serious injury.
Touch the vehicle or some other metal surface to discharge any static elec-
tricity.
Sparks resulting from discharging static electricity may cause the fuel
vapors to ignite.
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, pressurized fuel may spray out of the filler neck and cause
injury.
Do not allow anyone that has not discharged static electricity from their
bodies 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 igni-
tion hazard.
When replacing the fuel cap
Do not use anything but a genuine Lexus fuel tank cap designed for your
vehicle. Failure to do so may cause a fire or other incident which may result
in death or serious injury.

Be sure all items are secured in place.
Be careful to keep the vehicle level. Placing the weight as far
forward as possible helps maintain vehicle balance.
For better fuel economy, do not carry unnecessary weight.

mercial purposes are not covered by the Lexus warranty.
Ask your local authorized Lexus dealer or repairer, or another duly
qualified 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 draw bar load before towing. (P. 534)
Towing hitch/bracket
Lexus recommends the use of the Lexus hitch/bracket for
your vehicle. Other products of a suitable nature and compa-
rable quality may also be used.
