■Items to check before locking the vehicle
To prevent unexpected triggering of the alarm and vehicle theft, make sure of the
following.
●Nobody is in the vehicle.
●The windows and moon roof 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.
●The doors is unlocked using the key.
●A person inside the vehicle opens a door or hood.
●The battery is recharged or replaced when the vehicle is locked.
■Pa n ic m o d eVehicles with power back door
Vehicles without power back door
When PANIC is pushed for longer than
about one second, an alarm will sound for
about 30 seconds and the vehicle lights will
flash to deter any person from trying to break
into or damage your vehicle.
To stop the alarm, push any button on the
wireless remote control.

1-8. Safety information
RX400h_UWhile pushing the child restraint
system down into the rear seat,
allow the shoulder belt to retract
until the child restraint system is
securely in place.
After the shoulder belt has
retracted to a point where there is
no slack in the belt, pull the belt to
check that it cannot be extended.
■
Forward facing  Convertible seat
Place the child restraint system on
the seat facing the front of the vehi-
cle.
Run the seat belt through the child
restraint system and insert the
plate into the buckle. Make sure
that the belt is not twisted.
Fully extend the shoulder belt and
then allow it to retract slightly into
the ALR lock mode.
Lock mode allows the seat belt to
retract only.

2-1. Driving procedures
RX400h_U
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability of the
correct fuel. (→P. 4 3 3 )
■For efficient use of the hybrid battery
●Put the shift lever into D when driving
In the N position, the gasoline engine operates but electricity cannot be gener-
ated. The hybrid battery (traction battery) will be discharged requiring unnec-
essary engine power to recharge.
●Drive your vehicle smoothly
Avoid abrupt acceleration and deceleration. Gradual acceleration and decel-
eration will make more effective use of the traction motor without having to use
gasoline engine power.
●Avoid repeated acceleration
Repeated acceleration consumes hybrid battery (traction battery) power,
resulting in poor acceleration. Battery power can be restored by driving with
the accelerator pedal slightly released.
●Put the shift lever into P when parking
In the N position, the hybrid battery (traction battery) does not recharge.
Leaving the shift lever in the N position for an extended period of the time may
discharge the hybrid battery. The vehicle cannot run if the hybrid battery is dis-
charged.
■Normal characteristics after turning off the hybrid system
Approximately five hours after the hybrid system is turned off, you may hear sound
coming from under the vehicle for several minutes. This is the sound of a fuel evapo-
ration leakage check and, it does not indicate a malfunction.
CAUTION
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the hybrid system
running. This prevents the vehicle from creeping.

When driving
RX400h_U
CAUTION
■When driving the vehicle
●Do not drive if you are unfamiliar with the location of the brake and accelerator
pedals to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake pedal willresult in sudden acceleration that may lead to an accident that could result in
death or serious injury.
• When backing up, you may twist your body around, leading to a difficulty in operating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the vehicle
only slightly, allowing you to depress the brake and accelerator pedals prop-
erly.
• 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 acci-
dent.
●The driver should pay attention to pedestrians when the vehicle is powered only
by the electric motor (traction motor). Because there is no engine noise, the
pedestrians may misjudge the vehicle’s movement.
●Do not drive the vehicle over or stop the vehicle near flammable materials.
●Do not let the vehicle roll backwards while th e shift lever is in a driving position, or
roll forward while the shift lever is in R.
Doing so may cause the hybrid system to stall or lead to poor brake and steering
performance, resulting in an accident or damage to the vehicle.
●If the smell of exhaust is noticed inside the vehicle, open the windows and check
that the back door is closed. Large amounts of exhaust in the vehicle can cause
driver drowsiness and an accident, resulting in death or a serious health hazard.
Have the vehicle inspected by your Lexus dealer immediately.
●Do not under any circumstances shift the shift lever to P, R or N while the vehicle
is moving.
Doing so can cause significant damage to the transmission system and may result
in a loss of vehicle control.
●Do not shift the shift lever to N while the vehicle is moving.
Doing so may cause the engine brake to not operate properly and lead to an
accident.

CAUTION
■When the vehicle is stopped
●Do not race the hybrid system.
If the vehicle is in any gear other than P or N the vehicle may accelerate suddenly
and unexpectedly, and may cause an accident.
●Do not leave the vehicle with the hybrid system on for a long time.
If such a situation cannot be avoided, park the vehicle in an open space and
check that exhaust fumes do not enter the vehicle interior.
●Always keep a foot on the brake pedal while the hybrid system is operating to
prevent an accident caused by the vehicle moving.
■When the vehicle is parked
●Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in the vehi-
cle when it is in the sun.
Doing so may result in the following.
• Gas may leak from a cigarette lighter or spray can, and may lead to a fire.
• The temperature inside the vehicle may cause the plastic lenses and plasticmaterial of eye 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 compo-
nents.
●Always apply the parking brake, shift the shift lever to P, stop the hybrid system
and lock the vehicle.
Do not leave the vehicle unattended while the hybrid system operating.
●Do not touch the exhaust pipe while the hybrid system or immediately after turn-
ing the hybrid system off.
Doing so may cause burns.
●Do not leave the hybrid system operating in an area with snow build-up, or where
it is snowing. If snowbanks build up around the vehicle while the hybrid system is
operating, exhaust gases may collect and enter the vehicle. This may lead to
death or a serious health hazard.
