CAUTION
■Storage precautions
●Secure all items in the occupant compartment, as they may shift and
injure someone during sudden braking, sudden swerving or an acci-
dent.
●When you fold down the rear seats, long items should not be placed
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 t he event of sudden braking, sudden
swerving or an accident.
■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 deterioration of steering or braking con-
trol which may cause death or serious injury.
■Cross rail adjustment
Make sure the cross rails are locked securely by pushing forward and
rearward them.
Failure to do so may cause an unexpected accident.

CAUTION
■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. 798)
●Before driving, make sure the cargo is securely fastened on the roof
luggage carrier.
●Loading cargo on the roof luggage carrier will make the center of grav-
ity 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 150 lb. (68 kg) cargo weight on the roof luggage carrier.
NOTICE
■When loading cargo (vehicles with moon roof)
Be careful not to scratch th e surface of the moon roof.

● The trailer ball is set at the proper height for the coupler on the trai\
ler.
● The trailer is level when it is hitched.
Do not drive if the trailer is not level, and check for improper tongue
weight, overloading, 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, instal l rear view mirrors appropriate for
towing purposes.

CAUTION
■When towing a trailer
Toyota recommends trailers with brakes that conform to any applicable fed-
eral and state/provincial regulations.
●If the gross trailer weight exceeds unbraked TWR, trailer brakes are
required. Toyota recommends trailers with brakes that conform to all appli-
cable federal and state/provincial regulations.
● Never tap into your vehicle’s hydraulic system, as this will lower the vehi-
cle’s braking 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 Toyota 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.
