12 Volt DC Power Point
WARNING: Do not plug optional
electrical accessories into the cigar
lighter socket. Incorrect use of the cigar
lighter can cause damage not covered
by the vehicle warranty, and can result
in fire or serious injury.
Note: When you switch the ignition on, you
can use the socket to power 12 volt
appliances with a maximum current rating
of 15 amps.
If the power supply does not work after you
switch the ignition off, switch the ignition
on.
Note: Do not hang any accessory from the
accessory plug.
Note: Do not use the power point over the
vehicle capacity of 12 volt DC 180 watts or
a fuse may blow.
Note: Always keep the power point caps
closed when not in use.
Do not insert objects other than an
accessory plug into the power point. This
damages the power point and may blow
the fuse.
Run the vehicle for full capacity use of the
power point.
To prevent the battery from running out of
charge:
• Do not use the power point longer than
necessary when the vehicle is not
running.
• Do not leave devices plugged in
overnight or when you park your vehicle
for extended periods. Locations
Power points may be in the following
locations:
•
On the front of the center console.
• Inside the center console.

Adding Fuel From a Portable Fuel
Container
WARNING: Do not insert the nozzle
of a fuel container or an aftermarket
funnel into the fuel filler neck. This may
damage the fuel system filler neck or its
seal and cause fuel to run onto the
ground. WARNING: Do not try to pry open
or push open the capless fuel system
with foreign objects. This could damage
the fuel system and its seal and cause
injury to you or others. WARNING:
Do not dispose of fuel
in the household refuse or the public
sewage system. Use an authorized waste
disposal facility.
When refueling the vehicle fuel tank from
a fuel container, use the fuel filler funnel
included with your vehicle. See Fuel Filler
Funnel Location
(page 154).
Note: Do not use aftermarket funnels as
they may not work with the capless fuel
system and can damage it.
When refueling the vehicle fuel tank from
a fuel container, do the following:
1. Fully open the fuel filler door.
2. Fully insert the fuel filler funnel into the
fuel filler inlet. 3. Add fuel to your vehicle from the fuel
container.
4. Remove the fuel filler funnel.
5. Fully close the fuel filler door.
6. Clean the fuel filler funnel and place it back in your vehicle or correctly dispose
of it.
Note: Extra funnels can be purchased from
an authorized dealer if you choose to
dispose of the funnel.

TOWING A TRAILER - MACH 1
WARNING: Your vehicle is
not approved for trailer towing.
Never tow a trailer with your
vehicle.
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.
Note: There may be electrical
items such as fuses or relays that
can affect trailer towing operation.
See
Fuses (page 245).
The load capacity of your vehicle
is designated by weight not
volume. You may not necessarily
be able to use all available space
when loading your vehicle or
trailer. Towing a trailer places extra load
on the engine, transmission, axle,
brakes, tires, and suspension.
Inspect these components before,
during and after towing.
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 in the
center of 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 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
located in the Load Carrying
chapter. See
Load Limit (page
213).

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 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 270).
Replace fuses with the same type and
rating. See Changing a Fuse (page 254).
