WHAT IS THE POWER OUTLET
The power outlet can power devices using
a 12 V outlet adapter.
POWER OUTLET
PRECAUTIONS 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.
When you switch the vehicle on, you can
use the socket to power
12 V appliances
with a maximum current rating of 20 A. Do
not use the power point over the vehicle
capacity of
12 V DC 240 W or a fuse could
blow. Do not plug in any device that
supplies power to the vehicle through the
power points. This could result in damage
to vehicle systems. Do not hang any
accessory from the accessory plug. Always
keep the power point caps closed when
not in use. Do not insert objects other than
an accessory plug into 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 off.
• Do not leave devices plugged in
overnight or when you park your vehicle
for extended periods. LOCATING THE POWER
OUTLETS
Power outlets are in the following
locations:
•
On the instrument panel.
• Inside the center console.
• On the rear of the center console.

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
Locating
the Fuel Filler Funnel (page 260).
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:
If your vehicle runs out of fuel add a
minimum of
1.3 gal (5 L) of fuel to restart
the engine.
Note: You may need to switch the ignition
from off to on several times after refueling
to allow the fuel system to pump the fuel
from the tank to the engine. When
restarting, cranking time takes a few
seconds longer than normal.
Note: Extra funnels can be purchased from
an authorized dealer if you choose to
dispose of the funnel.

FUSE PRECAUTIONS
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. WARNING:
Always replace a fuse
with one that has the specified
amperage rating. Using a fuse with a
higher amperage rating can cause severe
wire damage and could start a fire. UNDER HOOD FUSE BOX
