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. 5 3 4 )

1753-4. Adjusting the steering wheel and mirrors
3
Operation of each component
RX350_U_OM48E90U 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 engine switch is in ACCESSORY or IGNITION ON mode. ■
When disconnecting and reconn ecting battery terminals (v ehicles with an automatic
folding/extending mirror function)
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. 5 0 0 )■
Automatic adjustment of the mirror angle (if equipped)
A desired mirror face angle can be entered to memory and recalled automatically by the
driving position memory. (  P. 1 6 2 )■
Auto anti-glare function (if equipped)
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 7 1 )■
Using automatic mode in cold weather (if equipped)
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 9 9 )Linked mirror function when reversing

200 4-1. Before driving
RX350_U_OM48E90U 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 0 4 ) 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.

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. 2 0 8 , 6 74
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. ■
