1184-1. Before driving
RC350/RC300 Owner's Manual
WARNING
• Make sure to keep a correct driving posture even when moving the vehicle
only slightly. This allows you to depress
the brake and accelerator pedals
properly.
• Depress the brake pedal using your right foot. Depressing the brake pedal
using your left foot may delay
response 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 flamma-
ble 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 emer-
gency, such as if it becomes impossible
to stop the vehicle in the normal way:
P.284
●Use engine braking (downshift) to
maintain a safe speed when driving
down a steep hill.
Using the brakes continuously may
cause the brakes to overheat and lose
effectiveness. (
P.129)
●Do not adjust the positions of the
steering wheel, the seat, or the inside
or outside rear view mirrors while driv-
ing.
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 per-
mits 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 not before drivin g at such speeds.
■When driving on slippery road sur-
faces
●Sudden braking, acceleration and
steering may cause tire slippage and
reduce your ability to control the vehi-
cle.
●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 prop-
erly. Wet brake pads may prevent the
brakes from functioning properly. If the
brakes on only one side are wet and
not functioning properly, steering con-
trol may be affected.
■When shifting the shift lever
●Do not let the vehicle roll backward
while the shift lever is in a driving posi-
tion, 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
performance, resulting in an accident
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 con-
trol.
●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 con-
trol.

Driving
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.

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.
