Operation of each component
When the engine switch is turned off,
the steering wheel returns to its stowed
position by moving up and away to
enable easier driver entry and exit.
Turning the engine switch to ACCES-
SORY or IGNITION ON mode will
return the steering wheel to the original
position.
To sound the horn, press on or close to
the mark.
■The steering wheel can be adjusted when (power type)
The engine switch is in ACCESSORY or IGNITION ON mode.
■Automatic adjustment of the steering position (if equipped)
A desired steering position ca n be entered to memory and recalled automatically by the
driving position memory system. (→ P. 169)
■Customization
The auto tilt away function can be changed. (Customizable features: →P. 673)

WARNING
■Caution while driving
Do not adjust the steeri ng wheel while driving.
Doing so may cause the driver to mishandle the vehicle and cause an accident, result-
ing in death or serious injury.
■After adjusting the steering wheel (manual type)
Make sure that the steering wheel is securely locked.
Otherwise, the steering wheel may move su ddenly, possibly causing an accident, and
resulting in death or serious injury. Also, th e horn may not sound if the steering wheel is
not securely locked.

Driving
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the engine running. This
prevents the vehicle from creeping.
■When driving the vehicle
●Do not drive if you are unfamiliar with the location of the brake and accelerator ped-
als to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake pedal will
result in sudden acceleration that may lead to an accident.
• When backing up, you may twist your body around, leading to a difficulty in oper-
ating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving po sture even when moving the vehicle only
slightly. This allows you to depress th e brake and accelerator pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake pedal using your left foot may delay re sponse in an emergency, resulting in an accident.
●Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. These hot parts may
cause a fire if there is any flammable material nearby.
●During normal driving, do not turn off the engine. Turning the engine off while driving
will not cause loss of steering or braking control, but the power assist to these systems
will be lost. This will make it more difficult to steer and brake, so you should pull over
and stop the vehicle as soon as it is safe to do so.
However, in the event of an emergency, such as if it becomes impossible to stop the
vehicle in the normal way: →P. 555
●Use engine braking (downshift) to maintain a safe speed when driving down a steep
hill.
Using the brakes continuously may cause th e brakes to overheat and lose effective-
ness. ( →P. 213)
●Do not adjust the positions of the steering wheel, the seat, or the inside or outside rear
view mirrors while driving.
Doing so may result in a loss of vehicle control.
●Always check that all passengers’ arms, heads or other parts of their body are not
outside the vehicle.
●Do not drive in excess of the speed limit. Even if the legal speed limit permits it, do not
drive over 85 mph (140 km/h) unless your vehicle has high-speed capability tires.
Driving over 85 mph (140 km/h ) may result in tire failure, loss of control and possible
injury. Be sure to consult a tire dealer to determine whether the tires on your vehicle
are high-speed capability tires or no t before driving at such speeds.

1964-1. Before driving
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When driving on slippery road surfaces
●Sudden braking, acceleration and steering may cause tire slippage and reduce your
ability to control the vehicle.
●Sudden acceleration, engine braking due to shifting, or changes in engine speed
could cause the vehicle to skid.
●After driving through a puddle , lightly depress the brake pedal to make sure that the
brakes are functioning properly. Wet brake pads may prevent the brakes from func-
tioning properly. If the brakes on only on e side are wet and not functioning properly,
steering control may be affected.
■When shifting the shift lever
●Do not let the vehicle roll backward while the shift lever is in a driving position, or roll
forward while the shift lever is in R.
Doing so may cause the engine to stall or lead to poor brake and steering perfor-
mance, resulting in an accide nt or damage to the vehicle.
●Do not shift the shift lever to P while the vehicle is moving.
Doing so can damage the transmission and may result in a loss of vehicle control.
●Do not shift the shift lever to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle control.
●Do not shift the shift lever to a driving position while the vehicle is moving backward.
Doing so can damage the transmission and may result in a loss of vehicle control.
●Moving the shift lever to N while the vehicle is moving will disengage the engine from
the transmission. Engine braking is not available when N is selected.
●Be careful not to shift the shift lever with the accelerator pedal depressed. Shifting the
shift lever to a gear other than P or N may lead to unexpected rapid acceleration of
the vehicle that may cause an accident and result in death or serious injury.
■If you hear a squealing or scraping noise (brake pad wear limit indicators) (RC350/
RC300/RC200t)
Have the brake pads checked and replaced by your Lexus dealer as soon as possible.
Rotor damage may result if the pads are not replaced when needed.
Front brakes on F SPORT models (RC350/R C200t only): Moderate levels of brake
pad and disc wear allow enhanced front braking power. As a result, the discs may wear
more quickly than conventional brake discs. Therefore, when replacing the brake pads,
Lexus recommends that you also have the thickness of th e discs measured.
It is dangerous to drive the vehicle when the wear limits of the brake pads and/or those
of the brake discs are exceeded.

2004-1. Before driving
NOTICE
■When driving the vehicle
●Do not depress the accelerator and brake pedals at the same time while driving, as
this may restrain the engine output.
●Do not use the accelerator pedal or depre ss the accelerator and brake pedals at the
same time to hold the vehicle on a hill.
■When parking the vehicle
Always set the parking brake, and shift the sh ift lever to P. Failure to do so may cause
the vehicle to move or the vehicle may accelerate suddenly if the accelerator pedal is
accidentally depressed.
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for an
extended period of time.
Doing so may damage the power steering motor.
●When driving over bumps in the road, drive as slowly as possible to avoid damaging
the wheels, underside of the vehicle, etc.
●RC200t: Make sure to idle the engine immediately after high-load driving. Stop the
engine only after the turb ocharger has cooled down.
Failure to do so may cause damage to the turbocharger.
■If you get a flat tire while driving
A flat or damaged tire may cause the following situations . Hold the steering wheel
firmly and gradually depress the brake pedal to slow down the vehicle.
●It may be difficult to control your vehicle.
●The vehicle will make abnormal sounds or vibrations.
●The vehicle will lean abnormally.
Information on what to do in case of a flat tire ( →P. 592, 606)
■When encountering flooded roads
Do not drive on a road that has flooded af ter heavy rain etc. Doing so may cause the
following serious damage to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be sure to have
your Lexus dealer check the following:
●Brake function
●Changes in quantity and quality of oil and fluid used for the engine, transmission,
transfer (AWD models), differential, etc.
●Lubricant condition for the propeller shaft, bearings and suspension joints (where
possible), and the function of all joints, bearings, etc.
