WARNING
●Check to make sure that all pas-
sengers do not have any part of
their body in a position where it
could be caught when the pan-
oramic moon roof is being oper-
ated.
●When using the wireless remote
control or mechanical key and
operating the panoramic moon
roof, operate the panoramic
moon roof afte r checking to
make sure that there is no pos-
sibility of any passenger having
any of their body parts caught in
the panoramic moon roof. Also,
do not let a child operate pan-
oramic moon roof by the wire-
less remote control or
mechanical key. It is possible for
children and other passengers
to get caught in the panoramic
moon roof.
●When exiting the vehicle, turn
the power switch to OFF, carry
the key and exit the vehicle
along with the child. There may
be accidental operation, due to
mischief, etc., that may possibly
lead to an accident.
■Jam protection function
●Never use any part of your body
to intentionally activate the jam
protection function.
●The jam protection function may
not work if something gets
caught just before the pan-
oramic moon roof or electronic
sunshade is fully closed. Also,
the jam protection function is
not designed to operate while
the switch is being pressed.
Take care so that your fingers,
etc. do not get caught.
■To prevent burns or injuries
Do not touch the area between
the underside of the panoramic
moon roof and the electronic sun-
shade. Your hand may get caught
and you could injure yourself.
Also, if the vehicle is left in direct
sunlight for a long time, the under-
side of the panoramic moon roof
could become very hot and could
cause burns.
NOTICE
■To prevent damage to the
panoramic moon roof
●Before opening the panoramic
moon roof, make sure that there
are no foreign objects, such as
stones or ice, around the open-
ing.
●Do not hit the surface or edge of
the panoramic moon roof with
hard objects.
●The panoramic moon roof
opens outside the vehicle,
thereby increasing the height of
the vehicle. Please use caution
when opening or driving with the
panoramic moon roof open
(pulling into low garages, etc.)

■Before towing
Check that the following conditions
are met:
●Ensure that your vehicle’s tires
are properly inflated. ( P.547)
●Trailer tires are inflated according
to the trailer manufacturer’s rec-
ommendation.
●All trailer lights work as required
by law.
●All lights work each time you con-
nect them.
●The trailer ball is set at the proper
height for the coupler on the
trailer.
●The trailer is level when it is
hitched. Do not dri ve if the trailer
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/provin-
cial or local regu lations. If they do
not, install rear view mirrors
appropriate for towing purposes.
Contact your Toyota dealer for
further information about addi-
tional requirements such as a
towing kit, etc.WARNING
■Trailer towing precautions
To tow a traile r safely, use
extreme care and drive the vehi-
cle in accordance with the trailer’s
characteristics and operating con-
ditions. Failure to do so could
cause an accident resulting in
death or serious injury. Vehicle
stability and brak ing performance
are affected by trailer stability,
brake setting and performance,
and the hitch. Your vehicle will
handle differently when towing a
trailer.
■To avoid accident or injury
●Do not exceed the TWR,
unbraked TWR, GCWR, GVWR
or GAWR.
●If the gross trailer weight is over
2000 lb. (900 kg), a sway con-
trol device with sufficient capac-
ity is required.
●If the gross trailer weight is over
5000 lb. (2200 kg), a weight dis-
tributing hitch with sufficient
capacity is required.
●Adjust the tongue weight within
the appropriate range. Place
heavier loads as close to the
trailer axle as possible.
●Do not exceed 65 mph (104
km/h), the posted towing speed
limit or the spee d limit for your
trailer as set forth in your trailer
owner’s manual, whichever is
lowest. Slow down sufficiently
before making a turn, in cross
winds, on wet or slippery sur-
face, etc., to hel p avoid an acci-
dent. If you experience a
vehicle-trailer instability from
reducing a certain speed, slow
down and make sure you keep
your vehicle speed under the
speed of which you experience
the instability.

 A recommended tongue
weight or kingpin weight var-
ies in accordance with the
types of trailers or towing as
described below.
 To ensure the recommended
values shown below, the
trailer must be loaded by
referring to the following
instructions.
1.Conventional Towing
The gross trailer weight should
be distributed so that the tongue
weight is 9% to 11%. (Tongue
Weight/Gross trailer weight x
100 = 9% to 11%)
Gross trailer weight
Tongue Weight
If using a weight d istributing hitch
when towing, return the front axle to
the same weight as before the
trailer connection.
If front axle weight cannot be mea-
sured directly, measure the front
fender height above the front axle
before connection. Adjust weight
distributing hitch torque until front fender is returned to the same
height as before connection.
Do not reduce front fender height
below original measurement.
The gross trailer weight, gross axle
weight and tongue weight can be
measured with platform scales
found at a highway weighing sta-
tion, building supply company,
trucking company, junk yard, etc.
2.Fifth wheel Towing or Goose-
neck Towing
The gross trailer weight should
be distributed so that the kingpin
weight is 14% to 16%. (Kingpin
weight/Gross trailer weight x
100 = 14% to 16%)
