TOWING A TRAILER
WARNINGS
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. Do not exceed the GVWR or
the GAWR specified on the
certification label. Note:
See Recommended
Towing Weights (page 49).
Your vehicle may have electrical
items, such as fuses or relays,
related to towing. See
Fuses
(page 68).
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 and load
capacity. 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
43).
You can also find information in
the
RV & Trailer Towing Guide
available at your authorized
dealer, or online.

WARNINGS
Use only adequately sized cables
with insulated clamps.
Preparing Your Vehicle
Do not attempt to push-start your
automatic transmission vehicle.
Note:
Attempting to push-start a vehicle
with an automatic transmission may cause
transmission damage.
Note: Use only a 12-volt supply to start your
vehicle.
Note: Do not disconnect the battery of the
disabled vehicle as this could damage the
vehicle electrical system.
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.

FUSE SPECIFICATION CHART
F53 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. Locate the power distribution box 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, you will need to reset some
features. See Changing the 12V Battery
(page 101).
