CAUTION
■When 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 electricity.
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, 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 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 ignition hazard.
■When replacing the fuel tank 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 seri-
ous injury.
NOTICE
■Refueling
Do not spill fuel during refueling. 
Failing to do so may damage the vehicle, such as causing the exhaust systems to
operate abnormally or damaging fuel system components or the vehicle’s painted
surface.

■Driving in the rain
●Drive carefully when it is raining, because visibility will be reduced, the windows
may become fogged-up, and the road will be slippery.
●Drive carefully when it starts to rain, because the road surface will be especially
slippery.
●Refrain from high speeds when driving on an expressway in the rain, because
there may be a layer of water between the tires and the road surface, preventing
the steering and brakes from operating properly.
■Breaking in your new Lexus
To extend the life of the vehicle, the following precautions are recommended to
observe:
●For the first 186 miles (300 km):
Avoid sudden stops.
●For the first 621 miles (1000 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in the low range in the “S” position.
• Do not drive at a constant speed for extended periods.
■Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type parking brake system.
This type of brake system needs bedding-down of the brake shoes periodically or
whenever the parking brake shoes and/or drums are replaced.
Have your Lexus dealer perform the bedding-down.
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability of the
correct fuel. (P. 5 8 9 )

AFS (Adaptive Front lighting System) (if equipped)
AFS improves visibility at intersections and on curves by automatically
adjusting the level of the headlights according to vehicle speed and the
degree of the tire angle that are controlled by steering input.
Operates at speeds of 6 mph (10 km/h) or higher.
■Deactivating AFS
Press the switch to turn it off.
The indicator turns on when
the AFS is deactivated.
■Daytime running light system
●To make your vehicle more visible to other drivers, the headlights turn on auto-
matically (at a reduced intensity) whenever the engine is started and the parking
brake is released. Daytime running lights are not designed for use at night.
●Compared to turning on the headlights, the daytime running light system offers
greater durability and consumes less electricity, so it can help improve fuel
economy.
