128 GETTING TO KNOW YOUR VEHICLE
If your vehicle is equipped with “Smart Fold”, the entire
center section of the 40/20/40 seat folds forward for access
of cupholders and console storage.Rear Armrest Cupholder With Smart FoldElectrical Power Outlets
The auxiliary 12 Volt (13 Amp) power outlet can provide
power for in-cab accessories designed for use with the
standard “cigar lighter” plug. The 12 Volt power outlets
and 5 Volt (2.5 Amp) USB Port (Charge Only) have a cap
attached to the outlet indicating “12V DC,” together with
either a key symbol, battery symbol, or USB symbol.
A key symbol indicates that the ignition must be in the ON/
RUN or ACC positions for the outlet to provide power. The
battery symbol indicates that the outlet is connected to the
battery, and can provide power at all times.
CAUTION!

• Do not exceed the maximum power of 160 Watts (13 Amps) at 12 Volts. If the 160 Watts (13 Amps) power rating is
exceeded, the fuse protecting the system will need to be
replaced.

• Power outlets are designed for accessory plugs only. Do not insert any other object in the power outlets as this
will damage the outlet and blow the fuse. Improper use
of the power outlet can cause damage not covered by
your New Vehicle Limited Warranty.

WARNING!
• When replacing a blown fuse, always use an appro -
priate replacement fuse with the same amp rating as the
original fuse. Never replace a fuse with another fuse of
higher amp rating. Never replace a blown fuse with
metal wires or any other material. Do not place a fuse
inside a circuit breaker cavity or vice versa. Failure to
use proper fuses may result in serious personal injury,
fire and/or property damage.
• Before replacing a fuse, make sure that the ignition is off and that all the other services are switched off and/
or disengaged.
• If the replaced fuse blows again, contact an authorized dealer.
• If a general protection fuse for safety systems (air bag system, braking system), power unit systems (engine
system, transmission system) or steering system blows,
contact an authorized dealer.

Internal Power Distribution Center
The Power Distribution Center is located under the drivers
side instrument panel. This center contains cartridge fuses,
micro fuses, relays, and circuit breakers. A description of
each fuse and component may be stamped on the inside
cover, otherwise the cavity number of each fuse is stamped
on the inside cover that corresponds to the following chart.
CAUTION!
• When installing the power distribution center cover, it is important to ensure the cover is properly positioned
and fully latched. Failure to do so may allow water to
get into the power distribution center and possibly
result in an electrical system failure.
• When replacing a blown fuse, it is important to use only a fuse having the correct amperage rating. The use
of a fuse with a rating other than indicated may result
in a dangerous electrical system overload. If a properly
rated fuse continues to blow, it indicates a problem in
the circuit that must be corrected.
