WARNING
●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 con-
trol.
●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 indica-
tors)
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.
It is dangerous to drive the vehicle when
the wear limits of the brake pads and/or
those of the brake discs are exceeded.
■When the vehicle is stopped
●Do not race the engine.
If the vehicle is in any gear other than P
or N, the vehicle may accelerate sud-
denly and unexpectedly, causing an
accident.
●In order to prevent accidents due to
the vehicle rolling away, always keep
depressing the brake pedal while the
engine is running, and apply the park-
ing brake as necessary.
●If the vehicle is sto pped on an incline,
in order to prevent accidents caused
by the vehicle rolling forward or back-
ward, always depress the brake pedal
and securely apply the parking brake
as needed.
●Avoid revving or racing the engine.
Running the engine at high speed
while the vehicle is stopped may cause
the exhaust system to overheat, which
could result in a fire if combustible
material is nearby.
■When the vehicle is parked
●Do not leave glasses, cigarette lighters,
spray cans, or soft drink cans in the
vehicle when it is in the sun.
Doing so may result in the following:
• Gas may leak from a cigarette lighter or spray can, and ma y lead to a fire.
• The temperature inside the vehicle may cause the plastic lenses and plas-
tic material of glasses to deform or
crack.
• Soft drink cans may fracture, causing the contents to spray over the interior
of the vehicle, and may also cause a
short circuit in the vehicle’s electrical
components.
●Do not leave cigarette lighters in the
vehicle. If a cigarette lighter is in a
place such as the glove box or on the
floor, it may be li t accidentally when
luggage is loaded or the seat is
adjusted, causing a fire.
●Do not attach adhesive discs to the
windshield or windows. Do not place
containers such as air fresheners on
the instrument panel or dashboard.
Adhesive discs or containers may act
as lenses, causing a fire in the vehicle.
●Do not leave a door or window open if
the curved glass is coated with a
metallized film such as a silver-colored
one. Reflected sunlight may cause the
glass to act as a lens, causing a fire.

1204-1. Before driving
RC350/RC300 Owner's Manual
WARNING
●Always apply the parking brake, shift
the shift lever to P, stop the engine and
lock the vehicle.
Do not leave the vehicle unattended
while the engine is running.
If the vehicle is parked with the shift
lever in P but the parking brake is not
set, the vehicle may start to move, pos-
sibly leading to an accident.
●Do not touch the exhaust pipes while
the engine is running or immediately
after turning the engine off.
Doing so may cause burns.
■When taking a nap in the vehicle
Always turn the engine off. Otherwise, if
you accidentally move the shift lever or
depress the accelerator pedal, this could
cause an accident or fire due to engine
overheating. Additionally, if the vehicle is
parked in a poorly ventilated area,
exhaust gases may collect and enter the
vehicle, leading to death or a serious
health hazard.
■When braking
●When the brakes are wet, drive more
cautiously.
Braking distance increases when the
brakes are wet, and this may cause one
side of the vehicle to brake differently
than the other side. Also, the parking
brake may not securely hold the vehi-
cle.
●If the brake booster device does not
operate, do not follow other vehicles
closely and avoid hills or sharp turns
that require braking.
In this case, braking is still possible, but
the brake pedal should be depressed
more firmly than usual. Also, the brak-
ing distance will increase. Have your
brakes fixed immediately.
●Do not pump the brake pedal if the
engine stalls.
Each push on the brake pedal uses up
the reserve for the power-assisted
brakes.
●The brake system consists of 2 individ-
ual hydraulic systems; if one of the sys-
tems fails, the other will still operate. In
this case, the brak e pedal should be
depressed more firmly than usual and
the braking distance will increase.
Have your brakes fixed immediately.
■If the vehicle becomes stuck
Do not spin the wheels excessively when
any of the tires is up in the air, or the vehi-
cle is stuck in sand, mud, etc. This may
damage the driveline components or
propel the vehicle forward or backward,
causing an accident.
NOTICE
■When driving the vehicle
●Do not depress the accelerator and
brake pedals at th e same time while
driving, as this may restrain the engine
output.
●Do not use the accelerator pedal or
depress 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 shift lever to P. Failure to do so may
cause the vehicle to move or the vehicle
may accelerate suddenly if the accelera-
tor 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.

WARNING
■When starting the engine
Always start the engi ne while sitting in
the driver’s seat. Do not depress the
accelerator pedal wh ile starting the
engine under any circumstances.
Doing so may cause an accident result-
ing in death or serious injury.
■Caution while driving
If engine failure occurs while the vehicle
is moving, do not lock or open the doors
until the vehicle reaches a safe and com-
plete stop. Activation of the steering lock
in this circumstance may lead to an acci-
dent, resulting in death or serious injury.
NOTICE
■When starting the engine
●Do not race a cold engine.
●If the engine becomes difficult to start
or stalls frequently, have your vehicle
checked by your Lexus dealer immedi-
ately.

■Locking the door from outside with the
engine running
1 With the driver’s door open, pull the
driver’s door handle and insert the
mechanical key.
2 Turn the mechanical key
counterclockwise.
3 Pull out the mechanical key and close
the door.
Modes can be changed by pressing
the engine switch with brake pedal
released. (The mode changes each

WARNING
■Stopping the engine in an emergency
If you want to stop the engine in an emer-
gency while driving the vehicle, press
and hold the engine switch for more than
2 seconds, or press it briefly 3 times or
more in succession. ( P.284)
However, do not touch the engine switch
while driving except in an emergency.
Turning the engine off while driving will
not cause loss of steering or braking con-
trol, 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.
■When parking
Exhaust gases include harmful carbon
monoxide (CO), which is colorless and
odorless. Observe the following precau-
tions.
Failure to do so may cause exhaust gases
to enter the vehicle and may lead to an
accident caused by light-headedness, or
may lead to death or a serious health
hazard.
●If the vehicle is in a poorly ventilated
area or a closed area, such as a
garage, stop the engine.
●Do not leave the vehicle with the
engine running for a long time. If such
a situation cannot be avoided, park the
vehicle in an open space and ensure
that exhaust fumes do not enter the
vehicle interior.
●Do not leave the engine running in an
area with snow build-up, or where it is
snowing. If snowbanks build up around
the vehicle while the engine is running,
exhaust gases may collect and enter
the vehicle.

driving conditions. When the “+” pad-
dle shift switch is operated, the shift
range will be one gear higher than the
gear in use during normal D position
