1784-1. Before driving
■Before towing
Check that the following conditions
are met:
●Ensure that your vehicle’s tires
are properly inflated. ( P.667)
●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 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/provin-
cial or local regu lations. If they do
not, install rear view mirrors
appropriate for towing purposes.
Toyota warranties do not
apply to damage or mal-
function caused by towing a
trailer for commercial pur-
poses.
Contact your Toyota dealer for
further information about addi-
tional requirements such as a
towing kit, etc.WARNING
■Trailer towing precautions
To tow a trailer 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. Yo ur vehicle will
handle differently when towing a
trailer.
■To avoid accident or injury
●Do not exceed the TWR,
unbraked TWR, GCWR, GVWR
or GAWR.
●Vehicles with towing package: If
the gross trailer weight is over
2000 lb. (907 kg), a sway con-
trol device with sufficient capac-
ity 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 help 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.
●Do not make jer ky, abrupt or
sharp turns.

■GCWR (Gross Combination
Weight Rating)
The maximum allowable gross
combination weight. The gross
combination weight is the sum
of the total vehicle weight
(including the occupants, cargo
and any optional equipment
installed on the vehicle) and the
weight of the trailer being towed
(including the cargo in the
trailer).
WARNING
●Do not apply the brakes sud-
denly as you may skid, resulting
in jackknifing and loss of vehicle
control. This is especially true
on wet or slippery surfaces.
●Do not exceed th e trailer hitch
assembly weight, gross vehicle
weight, gross axle weight and
trailer tongue weight capacities.
●Do not use dynamic radar
cruise control with full-speed
range when towing.
●Slow down and downshift
before descending steep or long
downhill grades. Do not make
sudden downshifts while
descending steep or long down-
hill grades.
●Vehicle-trailer instability is more
likely on steep long downhills.
Before descending steep or
long downhill grades, slow
down and downshift. Do not
make sudden downshifts when
descending steep or long down-
hill grades. Avoid holding the
brake pedal down too long or
applying the brakes too fre-
quently. This could cause the
brakes to overheat and result in
reduced braking efficiency.
●Do not tow a trailer when the
compact spare tire is installed
on your vehicle.
■When towing a trailer
Toyota recommends trailers with
brakes that confor m to any appli-
cable federal and state/provincial
regulations.
●If the gross tr ailer weight
exceeds unbraked TWR, trailer
brakes are required. Toyota rec-
ommends trailers with brakes
that conform to all applicable
federal and state/provincial reg-
ulations.
●Never tap into your vehicle’s
hydraulic system, as this will
lower the vehicle’s braking
effectiveness.
●Never tow a traile r without using
a safety chain securely attached
to both the trailer and the vehi-
cle. If damage occurs to the
coupling unit or hitch ball, there
is danger of the trailer wander-
ing into another lane.

1Pull up the opener to open
the fuel filler door. 2
Turn the fuel tank cap slowly
to open it and put it into the
holder on the fuel filler door.
After refueling, turn the fuel tank
cap until you hear a click. Once
the cap is released, it will turn
slightly in the opposite direction.
■When “Check Fuel Cap” is dis-
played on the multi-information
display
The fuel tank cap may be unfas-
tened or loose. Turn the engine
switch to OFF, check the cap and
tighten it securely. If the message
remains, wait a few seconds and
then turn the engine switch to OFF
once again.
WARNING
■When refueling
Observe the following precautions
to prevent fuel overflowing from
the fuel tank:
●Securely insert the fuel nozzle
into the fuel filler neck.
●Stop filling the tank after the fuel
nozzle automatically clicks off.
●Do not top off the fuel tank.
NOTICE
■Refueling
Do not spill fuel during refueling.
Doing so may damage the vehi-
cle, such as causing the emission
control system to operate abnor-
mally or damaging fuel system
components or the vehicle’s
painted surface.
