For your information
Main Owner’s Manual
Please note that this manual applies to all models and explains all equipment, includ-
ing options. Therefore, you may find some explanations for equipment not installed
on your vehicle.
All specifications provided in this manual are current at the time of printing. How-
ever, because of the Lexus policy of continual product improvement, we reserve the
right to make changes at any time without notice.
Depending on specifications, the vehicle shown in the illustration may differ from
your vehicle in terms of color and equipment.
Accessories, spare parts and modification of your Lexus
A wide variety of non-genuine spare parts and accessories for Lexus vehicles are
currently available in the market. You should know that Toyota does not warrant
these products and is not responsible for their performance, repair, or replacement,
or for any damage they may cause to, or adverse effect they may have on, your
Lexus vehicle.
This vehicle should not be modified with non-genuine Lexus products. Modification
with non-genuine Lexus products could affect its performance, safety or durability,
and may even violate governmental regulations. In addition, damage or perfor-
mance problems resulting from the modification may not be covered under war-
ranty.
Installation of a mobile two-way radio system
As the installation of a mobile two-way radio system in your vehicle may affect elec-
tronic systems such as the hybrid system, multiport fuel injection system/sequential
multiport fuel injection system, cruise control system, vehicle dynamics integrated
management, anti-lock brake system, SRS airbag system and seat belt pretensioner
system, be sure to check with your Lexus dealer for precautionary measures or spe-
cial instructions regarding installation.
High voltage parts and cables on the hybrid vehicles emit approximately the same
amount of electromagnetic waves as the conventional gasoline powered vehicles or
home electronic appliances despite of their electromagnetic shielding.

1-1. Hybrid system
RX400h_U
CAUTION
■Road accident cautions
Observe the following precautions to reduce the risk of injury.
●Pull your vehicle off the road, put the shift lever in P, apply the parking brake, turn
the hybrid system off and remove the key.
●Do not touch the high voltage parts, cables and connectors.
●If electric wires are exposed inside or outside your vehicle, an electric shock may
occur. Never touch exposed electric wires.
●If a fluid leak occurs, do not touch it as it may be strong alkaline electrolyte from
the hybrid battery (traction battery). If it comes into contact with your skin or
eyes, wash it off immediately with a large amount of water or if possible, boric
acid solution. Seek immediate medical attention.
●If a fire occurs in the hybrid vehicle, leave the vehicle as soon as possible. Never
use a fire extinguisher that is not meant for electric fires. Using even a small
amount of water may be dangerous.
●If your vehicle needs to be towed, do so with the front wheels (for 2WD models)
or four wheels (for AWD models) raised. If the wheels with the electric motor
(traction motor) are on the ground when towing, the motor may continue to gen-
erate electricity. This may cause an electricity leakage leading to a fire.(
→P. 3 7 8 )
■Nickel-metal hydride battery
Your vehicle contains a sealed nickel-metal hydride battery. If disposed of improp-
erly, it is hazardous to the environment and there is a risk of severe burns and elec-
trical shock that may result in death or serious injury.
■If the system activates
●Carefully check to see if there are exposed high voltage parts or cables. Never
touch the parts or cables. (
→P. 2 7 )
●Carefully inspect the ground under the vehicle. If you find that liquid has leaked
onto the ground, the fuel system may have been damaged. Leave the vehicle as
soon as possible.

1-3. Opening, closing and locking the doors
1
Before driving
RX400h_U
■The power back door can be opened when
The engine switch is in the ON position, and the shift lever is in P.
■Jam protection function
If anything obstructs the power back door while it is closing/opening, the back door
will automatically operate in the opposite direction.
■If the power back door does not work
The back door must be initialized. To initialize, close the back door completely by
hand.
■Customization that can be configured at Lexus dealer
Settings (e.g. beep sound) can be changed. (Customizable features →P. 4 5 8 )
CAUTION
Observe the following precautions.
Falling to do so may result in death or serious injury.
■Keep the back door closed while driving
If the back door is opening, the luggage will be thrown out and exhaust gases will be
entered in the vehicle.
■When the back door is opened while parking
The open back door hides the rear lights. Other road users must be warned of the
presence of your vehicle by a warning triangle or other device.
■Operating the power back door
●Check to make sure that passengers do not have any part of their body in a posi-
tion where it could be caught or hit when the back door is being operated.
●Careful attention is needed so as not to get your fingers trapped as the back door
automatically closes when it has not been fully closed.
●Do not allow children to operate the back door.
Closing the back door on someone can cause serious injury, and in some
instances, even death.

1-4. Adjustable components (seats, mirrors, steering wheel)
RX400h_U
CAUTION
■Seat adjustment
●Do not recline the seat more than necessary when the vehicle is in motion to
reduce the risk of sliding under the lap belt. If the seat is too reclined, the lap belt
may slide past the hips and apply restraint forces directly to the abdomen or your
neck may contact the shoulder belt, increasing the risk of death or serious injury
in the event of an accident.
●Be careful not to get hands or feet pinched between the rear console box and the
rear seat when folding down the rear seatback.
■When returning the seatback to the upright position
Observe the following precautions. Failure to do so may result in death or serious
injury.
●Press forward and rearward on the top of the seatback.
●Check that the seat belts are not twisted or caught under the seat.
●Arrange the seat belts in the proper positions for ready use.
NOTICE
■Stowing the seatbelts
The seat belts and the buckles must be stowed before you fold down the rear
seatbacks.

Driving position memory (if equipped)
Your preferred driving position (the position of the driver's seat, steering
wheel and outside rear view mirrors) can be memorized and recalled with
the touch of a button.
Two different driving positions can be entered into memory.
■ Entering a position to memory
Check that the shift lever is set in P.
Turn the engine switch to the ON position.
Adjust the driver’s seat, steering wheel, and outside rear view
mirrors to the desired positions. While pushing the SET button,
push button 1 or 2 until the sig-
nal beeps.
If the selected button has
already been preset, the previ-
ously recorded position will be
overwritten.
■Recalling the memorized position
Check that the shift lever is set in P.
Turn the engine switch to the ON position. Push button 1 or 2 to recall the
memorized position.

Before driving
RX400h_U
CAUTION
●Do not recline the seat any more than necessary to achieve a proper seating
position. The seat belt is most effective when the occupants are sitting up straight
and well back in the seats.
●Do not wear the shoulder belt under your arm.
●Always wear your seat belt low and snug across your hips.
■Seat belt pretensioners
●Do not place anything, such as a cushion, on the front passenger's seat. Doing so
will disperse the passenger's weight, which prevents the sensor from detecting
the passenger's weight properly. As a result, the seat belt pretensioner for the
front passenger's seat may not activate in the event of a collision.
●If the pretensioner has activated, the seat belt becomes locked: it cannot be fur-
ther extended, nor will it return to the stowed position. The seat belt cannot be
used again and must be replaced at your Lexus dealer.
■Child restraint lock function belt
Do not allow children to play with the child restraint lock function belt.
■Seat belt damage and wear
●Do not damage the seat belts by allowing the belt, plate, or buckle to be jammed
in the door.
●Inspect the seat belt system periodically. Check for cuts, fraying, and loose parts.
Do not use a damaged seat belt until it is replaced. Damaged seat belts cannot
protect an occupant from death or serious injury.
●Ensure that the belt and tab are locked and the belt is not twisted.
If the seat belt does not function correctly, immediately contact your Lexus
dealer.

1-5. Opening and closing the windows and moon roof
RX400h_U
CAUTION
■Closing the windows
Observe the following precautions.
Failing to do so may result in death or serious injury.
●Check to make sure that all passengers do not have any part of their body in a
position where it could be caught when a window is being operated.
●Do not allow children to operate the power windows.
Closing a power window on someone can cause serious injury, and in some
instances, even death.
■Jam protection function
●Never try jamming any part of your body to activate the jam protection function
intentionally.
●The jam protection function may not work if something gets caught just before
the window fully closes.
