2010 TOYOTA SIENNA tow

232 2-5. Driving information
CAUTION
■To avoid accident or injury
●Do not exceed the trailer hitch assembly weight, gross vehicle weight,
gross axle weight and trailer tongue load capacities.
● Never load more weight in the back than in the front of the trailer. About
60% of the load should be in the front half of the trailer, and the remaining
40% in the rear.
● Do not use cruise control when you are towing.
● Do not tow the vehicle with the compact spare tire installed.
■ Hitches
●Use only a hitch that conforms to the total trailer weight requirement.
● Follow the directions supplied by the hitch manufacturer.
● Lubricate the hitch ball with a light coat of grease.
● Remove the trailer hitch whenever you are not towing a trailer. After
removing the hitch, seal any mounting hole in the vehicle body to prevent
entry of any substances into the vehicle.
■ When towing a trailer
●If the gross trailer weight exceeds 1000 lb. (453 kg), 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.

Trailer towing tips
Your vehicle will handle differently when towing a trailer. The 3 main
causes of vehicle-trailer accidents are driver error, excessive speed
and improper trailer loading. Keep the following in mind when towing.
● Before starting out, check the trailer lights and the vehicle-trailer
connections. Recheck after driving a short distance.
● Practice turning, stopping and reve rsing with the trailer attached in
an area away from traffic until you become accustomed to the feel
of the vehicle.
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 use axle-mounted hitches, as they can cause damage to the axle
housing, wheel bearings, wheels or tires.
■ Brakes
Toyota recommends trailers with brakes that conform to all applicable fed-
eral and state/provincial regulations.
■ Safety chain
A safety chain must always be used between the towing vehicle and the
trailer. Leave sufficient slack in the chain for turns. The chain should cross
under the trailer tongue to prevent the tongue from dropping to the ground in
the case that it becomes damaged or separated. For the correct safety chain
installation procedure, ask your Toyota dealer.
■ Do not directly splice trailer lights
Directly splicing trailer lights may damage your vehicle's electrical system
and cause a malfunction.

234 2-5. Driving information
●Reversing with a trailer attached is difficult and requires practice.
Grip the bottom of the steering wheel and move your hand to the
left to move the trailer to the left. Move your hand to the right to
move the trailer to right. (This is generally opposite to reversing
without a trailer attached.) Avoid sharp or prolonged turning. Have
someone guide you when reversing to reduce the risk of an acci-
dent.
● As stopping distance is increased when towing a trailer, vehicle-to-
vehicle distance should be increased. For each 10 mph (16 km/h)
of speed, allow at least o ne vehicle and trailer length.
● Avoid sudden braking as you may skid, resulting in jackknifing and
loss of control. This is especiall y true on wet or slippery surfaces.
● Avoid jerky starts or sudden acceleration.
● Avoid jerky steering and sharp turns, and slow down before mak-
ing turns.
● Note that when making a turn, th e trailer wheels will be closer than
the vehicle wheels to the inside of the turn. Compensate by making
a larger than normal turning radius.
● Crosswinds and rough roads will adversely affect handling of your
vehicle and trailer, causing sway . Periodically check the rear to
prepare for being passed by large trucks or buses, which may
cause your vehicle and trailer to sway. If swaying occurs, firmly grip
the steering wheel, reduce speed immediately but gradually, and
steer straight ahead. Never increase speed. If you make no
extreme correction with the stee ring or brakes, your vehicle and
trailer will stabilize.
● Take care when passing other v ehicles. Passing requires consider-
able distance. After passing a vehi cle, do not forget the length of
your trailer, and be sure you hav e plenty of room before changing
lanes.
● In order to maintain efficient engine braking and electrical charging
performance, do not use overdrive.

236 2-5. Driving information
CAUTION
■To avoid an accident
●Do not exceed 45 mph (72 km/h) or posted towing speed limit, whichever
is lower. As instability (swaying) of the towing vehicle-trailer combination
increases as speed increases, exceeding 45 mph (72 km/h) may cause
loss of control.
● Slow down and downshift before descending steep or long downhill
grades. Do not make sudden downshifts.
● Avoid holding the brake pedal down too long or applying the brakes too
frequently. This could cause the brakes to overheat and result in reduced
braking efficiency.

Headphones
With some headphones generally available in the market, it may be difficult
to catch signals properly. Toyota recommends the use of Toyota genuine
wireless headphones.
Please contact your Toyota dealer for further details.
■ Vo l u m e
●Adjust the volume when you connect the headphones to the jack. Loud
sounds may have a significant impact on the human body.
● Conversational speech on some DVDs is recorded at a low volume to
emphasize the impact of sound effects. If you adjust the volume assum-
ing that the conversations represent the maximum volume level that the
DVD will play, you may be startled by louder sound effects or when you
change to a different audio source. Be sure to adjust the volume with this
in mind.
CAUTION
■While driving
Do not use headphones.
Doing so may cause an accident, resulting in death or serious injury.
■ When the rear seat entert ainment system is not used
Keep the display closed.
In the event of an accident or sudden braking, the opened display may hit an
occupant's body, resulting in injury.
■ To prevent accidents and electric shock
Do not disassemble or modify the remote controller.
■ When the remote controller is not used
Stow the remote controller.
Injuries may result in the event of an accident or sudden braking.
■ Removed battery and other parts
Keep away from children.
These parts are small and if swallowed by a child they can cause choking.
