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 the vehicle and could
result in engine damage, transmission damage, structural damage, loss
of vehicle control, vehicle rollover and personal injury.
Note:For information on electrical items such as fuses or relays, see the
Fuseschapter.
Your vehicle’s load capacity is designated by weight, not by volume, so
you cannot necessarily use all available space when loading a vehicle.
Towing a trailer places an additional 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 the vehicle when driving:
•Load the heaviest items closest to the trailer floor.
•Load the heaviest items so they are 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 tow 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 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 noted underLoad limitin theLoad Carryingchapter and
in theRV & Trailer Towing Guide,available at your authorized dealer.

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 located in the engine compartment. It has
high-current fuses that protect your vehicle’s main electrical systems
from overloads.
If the battery has been disconnected and reconnected, seeChanging the
Vehicle Batteryin theMaintenancechapter.
The high-current fuses are coded as follows:
