Servicing while towing
If you tow a trailer for long
distances, your vehicle requires
more frequent service than a
vehicle not used for towing. Refer

an intregal hitch and requires only
a ball with a 1 inch shank
diameter. The bumper has a 1814

kg (400 lb) tongue weight
capability.
Use a frame mounted weight
distributing hitch for trailers over
1814 kg (4000 lb).

avoiding:
²lack of regular, scheduled
maintenance
²excessive speed
²rapid acceleration
