WARNING
■Trailer towing precautions
To tow a trailer safely, use extreme care and drive the vehicle in accordance with the
trailer’s characteristics and operating conditions. Failure to do so could cause an acci-
dent resulting in deat h or serious injury. Vehicle stab ility and braking 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. (907 kg), a sway control device with suffi-
cient capacity is required.
●Adjust the tongue weight within the approp riate 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 speed limit
for your trailer as set forth in your trai ler owner’s manual, whichever is lowest. Slow
down sufficiently before making a turn, in cross winds, on wet or slippery surface, etc.
to help avoid an accident. If you experien ce 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 jerky, abrupt or sharp turns.
●Do not apply the brakes suddenly as you ma y skid, resulting in jackknifing and loss of
vehicle control. This is especially true on wet or slippery surfaces.
●Do not exceed the trailer hitch assembly weight, gross vehicle weight, gross axle
weight and trailer tongue weight capacities.
●Do not use the following systems when trailer towing.
• Cruise control
*• Dynamic radar cruise control*
• Dynamic radar cruise cont rol with full-speed range*
• LDA (Lane-Departure Alert with steering control)*• LKA (Lane-Keeping Assist)*
• PCS (Pre-Crash Safety system)*
• BSM (Blind Spot Monitor)
*: If equipped
●Slow down and downshift before descending steep or long downhill grades. Do not
make sudden downshifts while descending steep or long downhill 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 down-
shifts when descending steep or long downhill grades. Avoid ho lding 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.
●Do not tow a trailer when the compact sp are tire is installed on your vehicle.
