For safety and security
RX450h_U_OM0E013U ◆ Removing a child restraint system installed with a seat belt
Press the buckle release button and
fully retract the seat belt. When releasing the buckle, the child
restraint system ma y spring up due to
the rebound of the seat cushion.
Release the buckle while holding
down the child restraint system.
Since the seat belt automatically
reels itself, slowly return it to the
stowing position.

Road accident cautions
Observe the following precautions to reduce the risk of death or serious injury:●
Pull your vehicle off the road, shift the shift lever to P, apply the parking brake, and
turn the hybrid system off. ●
Do not touch the high voltage parts, cables and connectors. ●
If electric wires are exposed inside or ou tside your vehicle, an electric shock may
occur. Never touch exposed electric wires. ●
If a fluid leak occurs, do not touch the fluid 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 el ectric fires. Using even a small amount of
water may be dangerous. ●
If your vehicle needs to be towed, do so with front wheels (2WD models) or four
wheels (AWD models) raised. If the wheels connected to the electric motor (traction
motor) are on the ground when towing, the motor may continue to generate electric-
ity. This may cause a fire. (  P. 5 3 0 )●
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.

Jam protection function (power seat)
Observe the following precautions.
Failure to do so may result in death or serious injury.●
Never use any part of your body to intentio nally activate the jam protection function.●
The jam protection function may not work if something gets caught just before the
rear seatback is fully folded forward. Be careful not to get fingers or anything else
caught. ●
The jam protection function may not work depending on the shape of the object that
is caught. Be careful not to get fingers or anything else caught.
NOTICE ■
Stowing the seat belts
The seat belt for the rear center seat, seat belt buckles and armrest must be stowed
before you fold down the rear seatbacks. (  P. 443)

1873-4. Adjusting the steering wheel and mirrors
3
Operation of each component
RX450h_U_OM0E013U When the mirror select switch is in the “L” or “R” position, the outside rear view
mirrors will automatically angle downwards when the vehicle is reversing in
order to give a better view of the ground.
To disable this function, select neither “L” nor “R” of the mirror select switch. ■
Adjusting the mirror angle when the vehicle is reversing
With the shift lever in R, adjust the mirror angle at a desired position.
The adjusted angle will be memorized and the mirror will automatically tilt to
the memorized angle whenever the shift lever is shifted to R from next time. The memorized downward tilt position of the mirror is linked to the normal position
(angle adjusted with the shif t lever in other than R). Therefore, if the normal posi-
tion is changed after adjustment, th e tilt position will also change.
When the normal position is chang ed, readjust the angle in reversing.■
Mirror angle can be adjusted when
The power switch is in ACCESSORY or ON mode. ■
When disconnecting and reconnec ting 12-volt battery terminals
The automatic folding/extending mirror function will return to off as default. To turn the
function on, press the switch again to select on. ■
When the mirrors are fogged up
The outside rear view mirrors can be cleare d using the mirror defoggers. Turn on the
rear window defogger to turn on the outside rear view mirror defoggers. (  P. 4 0 9 )■
Automatic adjustment of the mirror angle
A desired mirror face angle can be entered to memory and recalled automatically by the
driving position memory. (  P. 1 74 )■
Auto anti-glare function
When the anti-glare inside rear view mirror is set to automatic mode, the outside rear
view mirrors will activate in conjunction with the anti-glare inside rear view mirror to
reduce reflected light. (  P. 1 8 3 )■
Using automatic mode in cold weather
When automatic mode is used in cold weather, the door mirror could freeze up and
automatic stowing and return may not be possible. In this case, remove any ice and snow
from the door mirror, then either operate th e mirror using manual mode or move the mir-
ror by hand. ■
Customization
Some functions can be customized. (  P. 6 0 7 )Linked mirror function when reversing

212 4-1. Before driving
RX450h_U_OM0E013U Cargo capacity depends on the to tal weight of the occupants.
(Cargo capacity) = (Total load capaci ty) — (Total weight of occupants)
Steps for Determining Correct Load Limit —
(1) Locate the statement “The combined weight of occupants and cargo should
never exceed XXX kg or XXX lbs.” on your vehicle’s placard.
(2) Determine the combined weight of the driver and passengers that will be
riding in your vehicle.
(3) Subtract the combined weight of the driver and passengers from XXX kg or
XXX lbs.
(4) The resulting figure equals the ava ilable amount of cargo and luggage load
capacity.
For example, if the “XXX” amount equals 1400 lbs. and there will be five 150
lb passengers in your vehicle, the am ount of available cargo and luggage load
capacity is 650 lbs. (1400  750 (5  150) = 650 lbs.)
(5) Determine the combined weight of luggage and cargo being loaded on the
vehicle. That weight may not safely exceed the available cargo and luggage
load capacity calculated in Step 4.
(6) If your vehicle will be towing a trailer, load from your trailer will be transferred
to your vehicle. Consult this manual to determine how this reduces the avail-
able cargo and luggage load capacity of your vehicle.
(  P. 2 1 6 ) Vehicles without towing package: Lexus does not recommend towing a trailer with
your vehicle. Your vehicle is not designed for trailer towing.Cargo and luggage Take notice of the following information about storage precautions, cargo
capacity and load.
Capacity and distribution

216 4-1. Before driving
RX450h_U_OM0E013U ◆ Total load capacity (vehicle capacity weight):  P. 5 8 2
Total load capacity means the combined weight of occupants, cargo and lug-
gage.
◆ Seating capacity: 5 occupants (Front 2, Rear 3)
Seating capacity means the maximum number of occupants whose estimated
average weight is 150 lb. (68 kg) per person.
◆ TWR (Trailer Weight Rating) (Vehicles with towing package):
 P. 220, 582
TWR means the maximum gross trailer weight (trailer weight plus its cargo
weight) that your vehicle is able to tow.
◆ TWR (Trailer Weight Rating) (Vehicles without towing package)
Lexus does not recommend towing a trailer with your vehicle.
◆ Cargo capacity
Cargo capacity may increase or decrea se depending on the weight and the
number of occupants. ■
Total load capacity and seating capacity
These details are also described on the tire and loading information label. (  P. 4 9 6 )Vehicle load limits Vehicle load limits include total load capacity, seating capacity, trailer weight
rating and cargo capacity.

Overloading the vehicle
Do not overload the vehicle.
It may not only cause damage to the tires, but also degrade steering and braking ability,
resulting in an accident.

Driving
RX450h_U_OM0E013U Contact your Lexus dealer for further in formation about additional requirements
such as a towing kit, etc.Trailer towing (vehicles with towing package) Your vehicle is designed primarily as a passenger-and-load-carrying vehicle.
Towing a trailer can have an adverse impact on handling, performance, brak-
ing, durability, and fuel consumption. Fo r your safety and the safety of others,
you must not overload your vehicle or trailer. You must also ensure that you
are using appropriate towing equipment, that the towing equipment has been
installed correctly and used properly, and that you employ the requisite driv-
ing habits.
Vehicle-trailer stability and braking pe rformance are affected by trailer sta-
bility, brake performance and setting, tr ailer brakes, the hitch and hitch sys-
tems (if equipped).
To tow a trailer safely, use extreme ca re and drive the vehicle in accordance
with your trailer’s characteristics and operating conditions.
Lexus warranties do not apply to damage or malfunction caused by towing a
trailer for commer cial purposes.
