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.
Your vehicle may have electrical
items, for example fuses or relays,
related to towing. See
Fuses
(page 151).
Your vehicle's load capacity
designation is by weight, not by
volume, so you cannot necessarily
use all available space when
loading your vehicle.
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 draw bar 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
correct trailer loading and setting
your vehicle up for towing is
located in another chapter of this
Owner's Manual. See
Load Limit
(page 120). You can also find the
information in the RV & Trailer
Towing Guide. See an authorized
dealer.

FUSE SPECIFICATION CHART
Engine Compartment Fuse 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. Note:
If your vehicle has dual batteries,
disconnecting the primary under hood
battery does not remove power from all
circuits.
The engine compartment fuse 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 173).
Replace fuses with the same type and
rating. See Changing a Fuse (page 159). 151
