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. WARNING:
Do not exceed
the lowest rating capacity for
your vehicle or trailer hitch.
Overloading your vehicle or
trailer hitch can impair your
vehicle stability and handling.
Failure to follow this instruction
could result in the loss of control
of your vehicle, personal injury or
death. WARNING:
Do not cut,
drill, weld or modify the trailer
hitch. Modifying the trailer hitch
could reduce the hitch rating. Note:
To prevent your trailer from
accumulating distance, and the
trailer information status appearing
when you restart your vehicle after
disconnecting your trailer, you must
deactivate your trailer. Using the
information display, go to the
Towing menu and then the Select
Trailer option. Select the No active
trailer option. See
Information
Displays (page 112).
Your vehicle may have electrical
items, such as fuses or relays,
related to towing. See
Fuses
(page 334).
Your vehicle may have ability to
modify trailer towing features.
See
General Information (page
112).
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.

WARNING: 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. WARNING: 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.
3. Once the disabled vehicle has been started, run both vehicle engines for an
additional three minutes before
disconnecting the jumper cables.
Removing the Jumper Cables
Remove the jumper cables in the reverse
order that they were connected.

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. 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 373).
Replace fuses with the same type and
rating. See Changing a Fuse (page 340).
