Trailer towing tips
Your vehicle will handle differently when towing a trailer. Help to avoid
an accident, death or serious injury, keep the following in mind when
towing:
● Speed limits for towing a trailer vary by state or province. Do not
exceed the posted towing speed limit.
● Toyota recommends that the vehicle-trailer speed limit is 65 mph
(104 km/h) on a flat, straight, dry road. Do not exceed this limit, the
posted towing speed limit or the speed limit for your trailer as set
forth in your trailer owner's manual, whichever is lowest. Instability
of the towing vehicle-trailer combination (trailer sway) increases as
speed increases. Exceeding speed limits may cause loss of control.
● Before starting out, check the trailer lights, tires and the vehicle-
trailer connections. Recheck after driving a short distance.
● Practice turning, stopping and reversing with the trailer attached in
an area away from traffic until you become accustomed to the feel
of the vehicle-trailer combination.
