RC F_U ■
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 peri odically or whenever the parking brake
shoes and/or drum are replaced. Have your Lexus dealer perform the bedding down
operation. ■
Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability of the cor-
rect fuel. (  P. 554)■
Brake pads and discs (RC F)
The brake pads and discs are designed for use under high load conditions. Therefore,
brake noise may be generated depending on the vehicle speed, braking force and vehi-
cle environment (temperature, humidity, etc.). ■
Idling time before engine stop (RC300)
To prevent damage to the turbocharger, allow the engine to idle immediately after high-
load driving.
Driving condition Idling time
Normal city driving or high-spe ed driving (at the highway speed
limit or recommended speed) Not necessary
Steep hill driving, co ntinuous driving (race track driving etc.) Approximately
1 minute

This function automatically operates during M mode. ●
By following the Shift-up indicator and sh ifting up accordingly, it is possible
to achieve improved fuel economy and reduced exhaust emissions. ●
The Gear Shift Indicator does not have a similar function for downshifting. ●
Depending on the driving conditions, the Gear Shift Indicator may not dis-
play the Shift-up indicator while driving in M mode.Gear Shift Indicator (RC F) 1

RC F_U With the headlights on, push the
lever away from you to turn on the
high beams. Pull the lever toward you to the center
position to turn the high beams off.
Pull the lever toward you and release
it to flash the high beams once. You can flash the high beams with the
headlights on or off. ■
Daytime running light system ●
The daytime running lights illuminate using th e same lights as the parking lights and illu-
minate brighter than the parking lights. ●
To make your vehicle more visible to other drivers during daytime driving, the daytime
running lights turn on automatically when a ll of the following conditions are met. (The
daytime running lights are not designed for use at night.)
• The engine is running
• The parking brake is released
• The headlight switch is in the (Canada only), or
* position
* : When the surroundings are bright
The daytime running lights remain on after they illuminate, even if the parking brake is set
again. ●
For the U.S.A.: Daytime running lights can be turned off by operating the switch.●
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.●
Vehicles with LED front turn signal lights: If a turn signal light is in use, the daytime run-
ning light, on the same side, is turned off. For emergency flashers, both are turned off. ■
Headlight control sensorTurning on the high beam headlights 1

The sensor may not function properly if an
object is placed on the sensor, or anything that
blocks the sensor is affixed to the windshield.
Doing so interferes with the sensor detecting
the level of ambient li ght and may cause the
automatic headlight system to malfunction.

Before refueling the vehicle
WARNING ■
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 discha rge static electricity
before refueling because sparks resulting fr om 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 fu el tank cap is loosened. Wait until the
sound cannot be heard before fully removing the cap. In hot weather, pressurized 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 th at 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 pe rson 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 nozz le into the fuel filler neck.●
Stop filling the tank after the fuel nozzle automatically clicks off.●
Do not top off the fuel tank.
