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:
Your vehicle may have
electrical items, such as fuses or
relays, related to towing. See
Fuses (page 233).
Your vehicle's load capacity
designation is by weight, not by
volume, so you cannot necessarily
use all available space when
loading a vehicle or trailer.
Towing a trailer places an extra
load on your vehicle's engine,
transmission, axle, brakes, tires
and suspension. Inspect these
components periodically during,
and after, any towing operation. Load Placement
To help minimize how trailer
movement affects your vehicle
when driving:
•
Load the heaviest items closest
to the trailer floor.
• Load the heaviest items
centered between 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 your
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
203).
You can also find information in
the
RV & Trailer Towing Guide
available at your authorized
dealer, or online.

FUSE SPECIFICATION CHART
Power Distribution Box
WARNINGS
Always disconnect the battery before
servicing high current fuses.
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 the vehicle's main electrical
systems from overloads.
If you disconnect and reconnect the
battery, you will need to reset some
features. See Changing the 12V Battery
(page 256).
