TOWING A TRAILER
WARNING: Do not exceed
the GVWR or the GAWR
specified on the certification
label. WARNING:
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 221).
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
192).
You can also find information in
the
RV & Trailer Towing Guide
available at your authorized
dealer, or online.

FUSE SPECIFICATION CHART
Power Distribution Box
WARNING: Always disconnect the
battery before servicing high current
fuses. WARNING:
To reduce risk of
electrical shock, always replace the
cover to the power distribution box
before reconnecting the battery or
refilling fluid reservoirs. The power distribution box is in the engine
compartment. It has high-current fuses
that protect your vehicle's main electrical
systems from overloads.
If you disconnect and reconnect the
battery, you need to reset some features.
See Changing the 12V Battery (page 246).
Replace fuses with the same type and
rating. See Changing a Fuse (page 230).
