TOWING A TRAILER
WARNINGS
Do not exceed the GVWR or
the GAWR specified on the
certification label. Towing trailers beyond the
maximum recommended
gross trailer weight exceeds the
limit of your vehicle and could
result in engine damage,
transmission damage, structural
damage, loss of vehicle control,
vehicle rollover and personal
injury. Note:
There may be electrical
items such as fuses or relays that
can affect trailer towing operation.
See Fuses (page 218).
The load capacity of your vehicle
is designated by weight not
volume. You may not necessarily
be able to use all available space
when loading your vehicle or
trailer.
Towing a trailer places extra load
on the engine, transmission, axle,
brakes, tires, and suspension.
Inspect these components before,
during and after towing. Load Placement
To help minimize how trailer
movement affects the vehicle
when driving:
•
Load the heaviest items closest
to the trailer floor.
• Load the heaviest items in the
center of the left and right side
trailer tires.
• Load the heaviest items above
the trailer axles or just slightly
forward toward the trailer
tongue. Do not allow the final
trailer tongue weight to go
above or below 10-15% of the
loaded trailer weight.
• Select a ball mount with the
correct rise or drop. When both
the loaded vehicle and trailer
are connected, the trailer frame
should be level, or slightly
angled down toward the
vehicle, when viewed from the
side.
When driving with a trailer or
payload, a slight takeoff vibration
or shudder may be present due to
the increased payload weight.
Additional information regarding
proper trailer loading and setting
your vehicle up for towing is
located in the Load Carrying
chapter. See
Load Limit (page
189).
You can also find information in
the
RV & Trailer Towing Guide
available at your authorized
dealer, or online.

reinstall it, line up the tabs with the grooves
on the panel, drop the panel back into
place, and then push it shut. To reach the fuse panel, first remove the
key code card.
After replacing a fuse, return the key code
card to the original position. To reinstall
the trim panel, lineup the tabs with the
grooves on the panel, drop the panel back
into place, and then push it shut to reinstall
the trim panel.
