For safety and security
RC350/RCF_U (OM24636U)
■System maintenance
The vehicle has a maintenance-free type alarm system.
■Items to check before locking the vehicle
To prevent unexpected triggering of the alarm and vehicle theft, make sure of the follow-
ing:
●Nobody is in the vehicle.
●The windows and moon roof (if equipped) are closed before the alarm is set.
●No valuables or other personal items are left in the vehicle.
■Triggering of the alarm
The alarm may be triggered in the following situations:
(Stopping the alarm deactivates the alarm system.)
■Alarm-operated door lock
The door automatically locks when the following occurs:
●When a person remaining in the vehicle unlocks the door and the alarm is activated.
●While the alarm is activated, a person remaining in the vehicle unlocks the door.
●A person inside the vehicle opens a door, the
trunk or hood, or unlocks the vehicle using a
inside lock button.
●The battery is recharged or replaced when the

■Suspension of the settings display
In the following situations, operation of the settings display will be temporarily sus-
pended.
●When a warning message appears on the multi-information display
●When the vehicle begins to move
■Tire pressure
●It may take a few minutes to display the tire inflation pressure after the engine switch is
turned to IGNITION ON mode. It may also take a few minutes to display the tire infla-
tion pressure after inflation pressure has been adjusted.
●“---” may be displayed if the tire information cannot be determined due to unfavorable
radio wave conditions.
●Tire inflation pressure changes with temperat ure. The displayed values may also be dif-
ferent from the values measured using a tire pressure gauge.
■When disconnecting and reconnecting battery terminals
The drive information data will be reset.
■Liquid crystal display

■Caution for use while driving
●When operating the multi-information display while driving, pay extra attention to the
safety of the area around the vehicle.
●Do not look continuously at the multi-info rmation display while driving as you may fail
to see pedestrians, objects on the road, etc. ahead of the vehicle.
■The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal information
display. At extremely low temperatures, th e information display monitor may respond
slowly, and display changes may be delayed.
For example, there is a lag between the driver’s shifting and the new gear number
appearing on the display. This lag could cau se the driver to downshift again, causing
rapid and excessive engine braking and po ssibly an accident resulting in death or
injury.
■Cautions during setting up the display
As the engine needs to be running during sett ing up the display, ensure that the vehicle
is parked in a place with adequate ventila tion. In a closed area such as a garage,
exhaust gases including harmful carbon mo noxide (CO) may collect and enter the
vehicle. This may lead to death or a serious health hazard.
NOTICE
■While setting up the display
To prevent battery discharge, ensure that th e engine is running while setting up the dis-
play features.

■Start-up display
When the engine is started, the name of the vehicle is displayed on the multi-information
display.
While the start-up display is being displaye d, the meter display cannot be changed even
if the drive mode is changed. When the start-up display is finished, the meter display for
the currently selected mode will be displayed.
■Torque distribution display (if equipped)
Torque distribution may not be displayed correctly in some cases, such as when the vehi-
cle passes over road expansion joints.
■G-force display
●The G-force values may not be zero even when the vehicle is parked, such as when it is
parked on an incline.
●The steering amount, accelerator pedal input, and brake fluid pressure displays are dis-
abled until the engine has warmed up (the variable red zone of the tachometer has
retracted to 7300 rpm).
After the engine has warmed up, these displays will be enabled.
●Depending on the vehicle usage conditions, the brake fluid pressure display may not
reach its maximum reading even though the brake pedal is fully depressed.
●If a battery terminal is disconnected and reconnected, the steering amount display may
be disabled temporarily. After driving the vehi cle for a while, the display will be enabled.

●“---” may be displayed if the tire position information cannot be determined due to
unfavorable radio wave conditions.
●Tire inflation pressure changes with temperat ure. The displayed values may also be dif-
ferent from the values measured using a tire pressure gauge.
■When disconnecting and reconnecting battery terminals
The following information data will be reset:
●Drive information
●Lap timer: Measured lap times, history
●G-force: Record of the maximum G-forces
■Using the lap timer

Operation of each component
RC350/RCF_U (OM24636U)
To take out the mechanical key, push
the release button and take the key out.
The mechanical key can only be
inserted in one direction, as the key only
has grooves on one side. If the key can-
not be inserted in a lock cylinder, turn it
over and re-attempt to insert it.
After using the mechanical key, store it
in the electronic key. Carry the mechan-
ical key together with the electronic key.
If the electronic key battery is depleted
or the entry function does not operate
properly, you will need the mechanical
key. (P. 5 9 0 )
■Panic mode
Using the mechanical key
When is pressed for longer than about
one second, an alarm will sound intermittently
and the vehicle lights will flash to deter any per-
son from trying to break into or damage your
vehicle.
To stop the alarm, press any button on the elec-
tronic key.

■Card key (if equipped)
●The card key is not waterproof.
●The mechanical key that is st ored inside the card key should be used only if a problem
arises, such as when the card key does not operate properly.
●If it is difficult to take out the mechanical key, push down the lock release button using a
pen tip etc. If it is still difficult to pull it out, use a coin etc.
■When required to leave the vehicle’s key with a parking attendant
Set the luggage security system ( P. 142) on and lock the glove box ( P. 432) as cir-
cumstances demand.
Remove the mechanical key for your own use and provide the attendant with the elec-
tronic key only.
■If you lose your mechanical keys
New genuine mechanical keys can be made by your Lexus dealer using another
mechanical key and the key number stamped on your key number plate. Keep the plate
in a safe place such as your wallet, not in the vehicle.
■When riding in an aircraft
When bringing an electronic key onto an aircraft, make sure you do not press any but-
tons on the electronic key while inside the airc raft cabin. If you are carrying an electronic
key in your bag etc., ensure that the buttons are not likely to be pressed accidentally.
Pressing a button may cause the electronic key to emit radio waves that could interfere
with the operation of the aircraft.
●To store the mechanical key in the card key,
insert it while pressing the lock release button.
●If the battery cover is not installed and the bat-
tery falls out or if the battery was removed
because the key got wet, reinstall the battery
with the positive terminal facing the Lexus
emblem.

half.)
●If the battery becomes low, an alarm will soun d in the cabin when the engine is stopped.
(  P. 5 5 7 )
●As the electronic key always receives ra dio waves, the battery will become depleted
even if the electronic key is not used. The following symptoms indicate that the elec-
tronic key battery may be depleted. Re place the battery when necessary. (P. 5 0 7 )
• The smart access system with push-button start or the wireless remote control does
not operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
●To avoid serious deterioration, do not leave the electronic key within 3 ft. (1 m) of the
following electrical appliances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
• Table lamps
• Induction cookers
■Replacing the battery
 P. 5 0 7
■Confirmation of the registered key number
The number of keys already registered to the vehicle can be confirmed. Ask your Lexus
