TOWING A TRAILER
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:
Do not exceed the GVWR or the
GAWR specified on the certification
label. See Recommended Towing
Weights (page 217).
Your vehicle may have electrical items,
such as fuses or relays, related to
towing.
See Fuses (page 246). 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
another chapter of this manual. See
Load Limit (page 211).
You can also find information in the
RV
& Trailer Towing Guide available at your
authorized dealer, or online.

Park the booster vehicle close to the hood
of the disabled vehicle, making sure the two
vehicles do not touch.
Connecting the Jumper Cables
WARNINGS
Do not attach the cables to fuel lines,
engine rocker covers, the intake
manifold or electrical components as
grounding points. Stay clear of moving parts.
To avoid reverse polarity connections, make
sure that you correctly identify the positive
(+) and negative (-) terminals on both the
disabled and booster vehicles before
connecting the cables. Do not attach the end of the positive
cable to the studs or L-shaped eyelet
located above the positive (+) terminal of
your vehicle ’s battery. High current may flow
through and cause damage to the fuses. Do not connect the end of the second
cable to the negative (-) terminal of the
battery to be jumped. A spark may cause an
explosion of the gases that surround the
battery. Note:
In the illustration, the bottom vehicle
represents the booster vehicle. 1. Connect the positive (+) jumper cable to
the positive (+) terminal of the discharged
battery.
2. Connect the other end of the positive (+)
cable to the positive (+) terminal of the
booster vehicle battery.
3. Connect the negative (-) cable to the negative (-) terminal of the booster
vehicle battery.
4. Make the final connection of the negative
(-) cable to an exposed metal part of the
stalled vehicle's engine, away from the
battery and the fuel injection system, or
connect the negative (-) cable to a ground
connection point if available.
Jump Starting
1. Start the engine of the booster vehicle and rev the engine moderately, or press
the accelerator gently to keep your
engine speed between 2000 and 3000
RPM, as shown in your tachometer.
2. Start the engine of the disabled vehicle.

FUSE SPECIFICATION CHART
Power Distribution Box
WARNINGS
Always disconnect the battery before
servicing high current fuses. WARNINGS
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 you disconnect and reconnect the battery,
you need to reset some features. See
Changing the 12V Battery (page 275). The high-current fuses are coded as follows:
