RC350/RC300 Owner's Manual
4-1.Before driving
■Starting the engine
 P.125
■Driving
1 With the brake pedal depressed,
shift the shift lever to D. ( P.129)
2 If the parking brake is in manual
mode, release the parking brake.
( P.135)
3 Gradually release the brake pedal
and gently depress the accelerator
pedal to accelerate the vehicle.
■Stopping
1 With the shift lever in D, depress the
brake pedal.
2 If necessary, set the parking brake.
If the vehicle is to be stopped for an
extended period of time, shift the shift lever
to P or N. ( P.129)
■Parking the vehicle
1 With the shift lever in D, depress the
brake pedal.
2 Set the parking brake ( P.135),
and shift the shift lever to P
(  P.129).
3 Press the engine switch to stop the
engine.
4 Lock the door, making sure that you
have the electronic key on your
person.
If parking on a hill, block the wheels as
needed.
■Starting off on a steep uphill
1 With the brake pedal depressed,
shift the shift lever to D.
2 Pull the parking brake switch to set
the parking brake manually.
3 Release the brake pedal and gently
depress the accelerator pedal to
accelerate the vehicle.
4 Press the parking brake switch to
release the parking brake manually.
■When starting off on an uphill
The hill-start assist control will activate.
( P.199)
■Driving in the rain
●Drive carefully when it is raining, because
visibility will be re duced, the windows
may become fogged-u p, and the road
will be slippery.
●Drive carefully when it starts to rain,
because the road surface will be espe-
cially 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 prop-
erly.
■Engine speed while driving
In the following conditions, the engine
speed may become high while driving. This
is due to automatic up-shifting control or
down-shifting implementation to meet driv-
ing conditions. It does not indicate sudden
acceleration.
●The vehicle is judged to be driving uphill
or downhill
●When the accelerato r pedal is released
●When the brake pedal is depressed while
sport mode is selected
Driving the vehicle
The following procedures should be
observed to ensure safe driving:
Driving procedure

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.

Driving
■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
time the switch is pressed.)
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.

WARNING
■When using the intuitive parking
assist
Observe the following precautions.
Failing to do so may result in the vehicle
being unable to be driven safely and pos-
sibly cause an accident.
●Do not use the sensor at speeds in
excess of 6 mph (10 km/h).
●The sensors’ detection areas and reac-
tion times are limited. When moving
forward or reversing, check the areas
surrounding the vehicle (especially the
sides of the vehicle) for safety, and
drive slowly, using the brake to control
the vehicle’s speed.
●Do not install accessories within the
sensors’ detection areas.
●The area directly under the bumpers is
not detected.
Thin posts or objects lower than a sen-
sor may not be detected when
approached, even if they have been
detected once.
■When to disable the function
In the following situations, disable the
function as it may operate even though
there is no possibility of a collision.
●The vehicle is equipped with a fender
pole, wireless antenna or fog lights.
●The front or rear bumper or a sensor
receives a strong impact.
●A non-genuine Lexus suspension
(lowered suspension, etc.) is installed.
●Towing eyelets are installed.
●A backlit license plate is installed.
■When using intuitive parking assist
In the following situations, the system
may not function correctly due to a sen-
sor malfunction, etc. Have the vehicle
checked by your Lexus dealer.
●The intuitive parking assist operation
display flashes or shows continuously,
and a buzzer sounds when no objects
are detected.
●If the area around a sensor collides
with something, or is subjected to
strong impact.
●If the bumper or grille collides with
something.
●If the display flashes or is displayed
continuously and a buzzer does not
sound, except when the mute function
has been turned on.
●If a display error oc curs, first check the
sensor.
If the error occurs even when there is
no ice, snow or mud on the sensor, it is
likely that the sensor is malfunctioning.
■Notes when washing the vehicle
Do not apply intensive bursts of water or
steam to the sensor area.
Doing so may result in the sensor mal-
functioning.
●When using a high pressure washer to
wash the vehicle, do not spray the sen-
sors directly, as doing so may cause a
sensor to malfunction.
●When using steam to clean the vehicle,
do not direct steam too close to the
sensors as doing so may cause a sen-
sor to malfunction.

Driving
■The intuitive parking assist can be oper-
ated when
●Front center sensors:
• The engine switch is in IGNITION ON
mode.
• The shift lever is in a position other than P or R.
• The vehicle speed is less than about 6 mph (10 km/h).
●Front corner sensors:
• The engine switch is in IGNITION ON mode.
• The shift lever is in a position other than P.
• The vehicle speed is less than about 6 mph (10 km/h).
(At any speed when the shift lever is in R)
●Rear corner and rear center sensors:
• The engine switch is in IGNITION ON mode.
• The shift lever is in R.
■Muting the buzzer sound
●To mute the buzzer sound:
The buzzer can be temporarily muted by
pressing “OK” of the meter control
switches while an obstacle detection dis-
play is shown on the multi-information dis-
play.
●To cancel the mute:
Mute will be automatically canceled in the
following situations.
• When the shift position is changed (except shifting from D to N, or N to D).
• When the vehicle speed has reached or
exceeded 6 mph (10 km/h) with the shift
position in D.
• When the intuitive parking assist is turned
off once and turned on again.
• When the engine swit ch is turned off
once and turned to IGNITION ON
mode again.
■If “Clean Parking Assist Sensor” is dis-
played on the multi-information display
A sensor may be covered with ice, snow,
dirt, etc. Remove the ice, snow, dirt, etc.,
from the sensor to return the system to nor-
mal.
Also, due to ice forming on a sensor at low
temperatures, a warning message may be displayed or the sensor may not be able to
detect an object. Once the ice melts, the
system will return to normal.
■Sensor detection information
●The following situations may occur
during use.
• The sensors may be able to only detect objects near the fron t and rear bumpers.
• Depending on the sh ape of the object
and other factors, the detection distance
may shorten, or detection may be impos-
sible.
• There will be a short delay between object detection and di splay. Even at low
speeds, there is a possibility that the
object will come wi thin the sensor’s
detection areas befo re the display is
shown and the warning beep sounds.
• It might be difficult to hear the buzzer due to the volume of the audio system or air
flow noise of the air conditioning system.
• It may be difficult to hear the buzzer if buzzers for other systems are sounding.
■Conditions under which the function
may not function correctly
Certain vehicle conditions and the sur-
rounding environment may affect the ability
of a sensor to correctly detect objects. Par-
ticular instances where this may occur are
listed below.
●There is dirt, snow or ice on a sensor.
(Cleaning the sensors will resolve this
problem.)
●A sensor is frozen. (Thawing the area will
resolve this problem.)
In especially cold weat her, if a sensor is
frozen the sensor display may be dis-
played abnormally, or objects, such as a
wall, may not be detected.
●A sensor is covered in any way.
●When a sensor or the area around a sen-
sor is extremely hot or cold.
●On an extremely bumpy road, on an
incline, on gravel, or on grass.
●The vicinity of the vehicle is noisy due to
vehicle horns, motorcycle engines, air
brakes of large vehicles, or other loud
noises producing ultrasonic waves.
●There is another vehicle equipped with
