■Rear view monitor camera
■When the back door is open
The screen cannot be used because a message is displayed.
When backing up the vehicle, make sure the back door is securely closed.The rear view monitor camera is located on
the back door as shown in the illustration. The
camera uses a special lens. The distance of
the image that appears on the screen differs
from the actual distance.
In the following cases, it may be difficult to
see images on the screen even when the sys-
tem is functioning correctly:
●The vehicle is in a dark area, such as at
night.
●The temperature near the lens is extremely
high or low.
●Water droplets are on the camera lens or
humidity is high, such as when it rains.
●Foreign matter, such as snow and mud,
adheres to the camera lens.
●The camera has scratches or dirt on it.
●The sun or headlights are shining directly
into the camera lens.

■When the four-wheel drive control switch can be operated
●The “ENGINE START STOP” switch is in IGNITION ON mode.
●The shift lever is in the N position.
●The vehicle is stopped completely.
■The low speed four-wheel drive indicator light
●The indicator light blinks while switching between H4 and L4.
●If the low speed four-wheel drive indicator light continues to blink when you
operate the four-wheel drive control switch to the H4 or L4 position, stop the
vehicle completely, shift the shift lever securely into N and then operate the
switch again.
●If the shift lever is moved before the low speed four-wheel drive indicator turns
on/off, the transfer mode may not be shifted completely. The transfer mode dis-
engages both the front and rear drive shafts from the powertrain and allows the
vehicle to move regardless of the shift position. (At this time, the indicator blinks
and the buzzer sounds.)
Therefore, the vehicle is free to roll even if the shift lever is in P. You or someone
else could be seriously injured. You must complete the shifting of the transfer
mode and confirm that the indicator light has turned off (H4) or turned on (L4).
●If the engine coolant temperature is too low, the four-wheel drive control system
may not be able to shift. When the engine is warmer operate the switch again.
If the indicator continue to blink even if doing so, have the vehicle inspected by your
Lexus dealer as soon as possible. There may be a trouble in the four-wheel drive
system.

Cargo and luggage
Take notice of the following information about storage precautions, cargo
capacity and load:
●Stow cargo and luggage in the luggage compartment whenever

● To maintain vehicle balance while driving, position luggage evenly
within the luggage compartment.
● For better fuel economy, do not carry unnecessary weight.

CAUTION
■Storage precautions
Observe the following precautions.
Failure to do so may result in death or serious injury.
●Stow cargo and luggage in the luggage compartment whenever possible.
●Do not stack cargo and luggage in the luggage compartment higher than the
seatbacks.
Such items may be thrown about and possibly injure people in the vehicle in the
event of a sudden braking, sudden swerving or an accident.
●Do not place cargo or luggage in or on the following locations as the item may
get under the brake or accelerator pedal and prevent the pedals from being
depressed properly, block the driver’s vision, or hit the driver or passengers,
causing an accident:
• At the feet of the driver
• On the front passenger or rear seats (when stacking items)
• On the luggage cover
• On the instrument panel
•On the dashboard
●Secure all items in the occupant compartment, as they may shift and injure some-
one in the event of a sudden braking, sudden swerving or an accident.
●When you fold down the rear seats, long items should not be place directly
behind the front seats.
●Never allow anyone to ride in the luggage compartment. It is not designed for
passengers. They should ride in their seats with their seat belts properly fastened.
Otherwise, they are much more likely to suffer death or serious bodily injury, in
the event of sudden braking or an accident.
■Roof luggage carrier precautions
To use the roof rails as a roof luggage carrier, you must fit the roof rails with two or
more genuine Lexus cross rails or their equivalent.
Follow the manufacturer’s instructions and precautions when installing the cross
rails or their equivalent.

CAUTION
■Capacity and distribution
●Do not exceed the maximum axle weight rating or the total vehicle weight rating.
●Even if the total load of occupant’s weight and the cargo load is less than the total
load capacity, do not apply the load unevenly. Improper loading may cause dete-
rioration of steering or braking control which may cause death or serious injury.
■When loading cargo
Observe the following precautions:
●Place the cargo so that its weight is distributed evenly between the front and rear
axles.
●If loading long or wide cargo, never exceed the vehicle overall length or width.
(→ P. 7 5 2 )
●Before driving, make sure the cargo is securely fastened to the roof luggage car-
rier.
●Loading cargo on the roof luggage carrier will make the center of gravity of the
vehicle higher. Avoid high speeds, sudden starts, sharp turns, sudden braking or
abrupt maneuvers, otherwise it may result in loss of control or vehicle rollover
due to failure to operate this vehicle correctly and result in death or serious injury.
●If driving for a long distance, on rough roads, or at high speeds, stop the vehicle
now and then during the trip to make sure the cargo remains in its place.
●Do not exceed 176lb. (80 kg) cargo weight on the roof luggage carrier.
NOTICE
■When loading cargo
Be careful not to scratch the surface of the moon roof.

■Matching trailer ball height to trailer coupler height
■Before towing
Check that the following conditions are met:
●Ensure that your vehicle’s tires are properly inflated. (→P. 76 2 )
●Trailer tires are inflated according to the trailer manufacturer’s recommenda-
tion.
●All trailer lights work as required by law.
●All lights work each time you connect them.
●The trailer ball is set at the proper height for the coupler on the trailer.
●The vehicle remains level when a loaded or unloaded trailer is hitched. Do not
drive if the vehicle is not level, and check for improper tongue weight, overload-
ing, worn suspension, or other possible causes.
●The trailer cargo is securely loaded.
●The rear view mirrors conform to all applicable federal, state/provincial or local
regulations. If they do not, install rear view mirrors appropriate for towing pur-
poses. No matter which class of tow hitch applies,
for a more safe trailer hookup, the trailer ball
setup must be the proper height for the cou-
pler on the trailer.

CAUTION
■Hitch
Trailer hitch assemblies have different weight capacities established by the hitch
manufacturer. Even though the vehicle may be physically capable of towing a
higher weight, the operator must determine the maximum weight rating of the par-
ticular hitch assembly and never exceed the maximum weight rating specified for
the trailer-hitch. Exceeding the maximum weight rating set by the trailer-hitch man-
ufacturer can cause an accident resulting in death or serious personal injuries.
■When towing a trailer
Lexus recommends trailers with brakes that conform to any applicable federal and
state/provincial regulations.
●If the gross trailer weight exceeds unbraked TWR, trailer brakes are required.
Lexus recommends trailers with brakes that conform to all applicable federal and
state/provincial regulations.
●Never tap into your vehicle’s hydraulic system, as this will lower the vehicle’s brak-
ing effectiveness.
●Never tow a trailer without using a safety chain securely attached to both the
trailer and the vehicle. If damage occurs to the coupling unit or hitch ball, there is
danger of the trailer wandering into another lane.
NOTICE
■When installing a trailer hitch
Use only the position recommended by your Lexus dealer. Do not install the trailer
hitch on the bumper; this may cause body damage.
■Do not directly splice trailer lights
Do not directly splice trailer lights. Directly splicing trailer lights may damage your
vehicle’s electrical system and cause a malfunction.
