Driving
■Maintenance
●If you tow a trailer, your vehicle will require more frequent maintenance due
to  the  additional  load.  (See  “Scheduled  Maintenance  Guide”  or  “Owner’s
Manual Supplement”.)
● Retighten the fixing bolts of the towing ball and bracket after approximately
600 miles (1000 km) of trailer towing.
■ If trailer sway occurs
One  or  more  factors  (crosswinds,  passing  vehicles,  rough  roads,  etc.)  can
adversely affect handling of your vehicle and trailer, causing instability.
●If trailer swaying occurs:
• Firmly grip the steering wheel. Steer straight ahead. 
Do not try to control trailer swaying by turning the steering wheel.
• Begin  releasing  the  accelerator  pedal  immediately  but  very  gradually  to reduce speed. 
Do not increase speed. Do not apply vehicle brakes.
If  you  make  no  extreme  correction  with  the  steering  or  brakes,  your  vehicle
and trailer should stabilize.
● After the trailer swaying has stopped:
• Stop in a safe place. Get all occupants out of the vehicle.
• Check the tires of the vehicle and the trailer.
• Check the load in the trailer. 
Make sure the load has not shifted. 
Make sure the tongue weight is appropriate, if possible.
• Check the load in the vehicle.  Make sure the vehicle is not overloaded after occupants get in.
If you cannot find any problems, the speed at which trailer swaying occurred
is beyond the limit of your particular vehicle-trailer combination. 
Drive  at  a  lower  speed  to  prevent  instability.  Remember  that  swaying  of  the
towing vehicle-trailer increases as speed increases.
