The rear bumper of your vehicle is
equipped with a hole to install a
trailer ball. If you have any ques-
tions, contact your Toyota dealer.
The gross trailer weight (trailer
weight plus cargo weight) when
towing with the bumper must never
exceed the TWR ( P. 201) or
5000 lb. (2268 kg) whichever is
lower.
Use the correct trailer ball for your application.
Trailer ball load rating
Matches or exceeds the gross
trailer weight rating of the trailer.
Ball diameter
Matches the size of the trailer cou-
pler. Most couplers are stamped
with the required trailer ball size.
Shank length
Protrudes beyond the bottom of the lock washer and nut by at le ast 2
threads.
Shank diameter
Matches the ball mount hole diameter size.

Your vehicle will handle differently when towing a trailer. To help avoid
an accident, death or serious injury, keep the following in min d when
towing:
● Speed limits for towing a trailer vary by state or province. Do not
exceed the posted to wing speed limit.
● Toyota recommends that the vehicl e-trailer speed limit is 65 mph
(104 km/h) on a flat, straight, dry road. Do not exceed this li mit, the
posted towing speed limit or the speed limit for your trailer a s set
forth in your trailer owner’s manu al, whichever is lowest. Instability
of the towing vehicle-trailer combination (trailer sway) increa ses as
speed increases. Exceeding speed limits may cause loss of contr ol.
● Before starting out, check the trailer lights, tires and the vehicle-
trailer connections. Recheck af ter driving a short distance.
● Practice turning, stopping and reversing with the trailer attac hed in
an area away from traffic until you become accustomed to the fe el
of the vehicle-trailer combination.
● Reversing with a trailer attached is difficult and requires pra ctice.
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 rig ht to
move the trailer to the right. (This is generally opposite to r eversing
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, vehicl e-to-
vehicle distance should be increased. For each 10 mph (16 km/h)
of speed, allow at least one v ehicle and trailer length.
