ailering is different than just driving the
vehicle by itself. Trailering affects in handling,
acceleration, braking, durability, and fuel
economy on your vehicle. Successful, safe
trailering takes correct equipment, and it has to
be used properly.
The following information has many time-
tested, important trailering tips and safety
rules. Many of these are important for your
safety and that of your passengers. Read this
section carefully before pulling atrailer.
When towing atrailer:
•
Become familiar with, and follow all
state and local laws that apply to trailer
towing. These requirements vary from
state to state.
•
State laws may require the use of extended
side view mirrors. If your visibility is limited
or restricted while towing, install extended
side view mirrors on your vehicle, even if
not required.
•
Do not tow a trailer during the first 800 km
(500 mi) of vehicle use to prevent damage
to the engine, axle, or other parts.
•
Pe
rform the first oil change before
heavy towing.
•
Do not drive over 80 km/h (50 mph) and do
not make starts at full throttle during the
