118 Instruments and Controls
{Warning
Power is always supplied to the
rear cargo power outlet. Do not
leave electrical equipment
plugged in when the vehicle is not
in use because the vehicle could
catch fire and cause injury or
death.
Certain accessory plugs may not be
compatible with the accessory
power outlet and could overload
vehicle and adapter fuses. If a
problem is experienced, see your
dealer.
When adding electrical equipment,
be sure to follow the proper
installation instructions included with
the equipment. See Add-On
Electrical Equipment 0242.
Caution
Hanging heavy equipment from
the power outlet can cause
damage not covered by the
vehicle warranty. The power
outlets are designed for
accessory power plugs only, such
as cell phone charge cords.
Power Outlet 110/120 Volt
Alternating Current
If equipped, this power outlet can be
used to plug in electrical equipment
that uses a maximum limit of 400
watts.
The power outlet is on the rear of
the center console.
An indicator light on the outlet turns
on to show it is in use. The light
comes on when the ignition is on
and equipment requiring less than
400 watts is plugged into the outlet,
and no system fault is detected.
The indicator light does not come on
when the ignition is off or if the
equipment is not fully seated into
the outlet.
If equipment is connected using
more than 400 watts or a system
fault is detected, a protection circuit
shuts off the power supply and the

164 Lighting
Turn and Lane-Change
Signals
Move the lever all the way up or
down to signal a turn.
An arrow on the instrument cluster
flashes in the direction of the turn or
lane change.Raise or lower the lever until the
arrow starts to flash to signal a lane
change. Hold it there until the lane
change is completed. If the lever is
briefly pressed and released, the
turn signal flashes three times.
The turn and lane-change signal
can be turned off manually by
moving the lever back to its original
position.
If after signaling a turn or lane
change, the arrow flashes rapidly or
does not come on, a signal bulb
may be burned out.
Replace any burned out bulbs. If a
bulb is not burned out, check the
fuse. See
Fuses and Circuit
Breakers 0271.
Fog Lamps
The ignition and the parking lamps
or headlamps must be on for the
front fog lamps to work.
#:If equipped, press to turn on or
off. An indicator light on the
instrument cluster comes on when
the fog lamps are on.
Some localities have laws that
require the headlamps to be on
along with the fog lamps.

Engine Oil
To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment: .
Use engine oil approved to the
proper specification and of the
proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section.
. Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
. Change the engine oil at the
appropriate time. See Engine Oil
Life System 0252.
. Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking Engine Oil
Check the engine oil level regularly,
every 650 km (400 mi), especially
prior to a long trip. The engine oil
dipstick handle is a loop. See
Engine Compartment Overview
0247 for the location.
{Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.
If a low oil Driver Information Center
(DIC) message displays, check the
oil level.
Follow these guidelines:
. To get an accurate reading, park
the vehicle on level ground.
Check the engine oil level after
the engine has been off for at
least two hours. Checking the
engine oil level on steep grades
or too soon after engine shutoff
can result in incorrect readings.
Accuracy improves when
checking a cold engine prior to
starting. Remove the dipstick
and check the level.
. If unable to wait two hours, the
engine must be off for at least
15 minutes if the engine is
warm, or at least 30 minutes if

270 Vehicle Care
To replace one of these bulbs:1. Push the left end of the lamp assembly toward the right.
2. Turn the lamp assembly down to remove it.
3. Turn the bulb socket (1) counterclockwise to remove it
from the lamp assembly (3).
4. Pull the bulb (2) straight out of the bulb socket (1).
5. Push the replacement bulb straight into the bulb socket
and turn the bulb socket
clockwise to install it into the
lamp assembly.
6. Turn the lamp assembly into the lamp assembly opening
engaging the clip side first.
7. Push on the lamp side opposite the clip until the lamp assembly
snaps into place.Electrical System
Electrical System
Overload
The vehicle has fuses and circuit
breakers to protect against an
electrical system overload.
When the electrical load current is
too heavy, the circuit breaker opens
and closes, protecting the circuit
until the current load returns to
normal or the problem is fixed. This
greatly reduces the chance of circuit
overload and fire caused by
electrical problems.
Replace a bad fuse with a new one
of the identical size and rating.
If there is a problem on the road and
a fuse needs to be replaced, the
same amperage fuse can be
borrowed. Choose some feature of
the vehicle that is not needed to use
and replace it as soon as possible.
Headlamp Wiring
An electrical overload may cause
the lamps to go on and off, or in
some cases to remain off. Have the
headlamp wiring checked right away
if the lamps go on and off or
remain off.
Windshield Wipers
If the wiper motor overheats due to
heavy snow or ice, the windshield
wipers will stop until the motor cools
and will then restart.
Although the circuit is protected
from electrical overload, overload
due to heavy snow or ice may
cause wiper linkage damage.
Always clear ice and heavy snow
from the windshield before using the
windshield wipers.
If the overload is caused by an
electrical problem and not snow or
ice, be sure to get it fixed.

Vehicle Care 271
Fuses and Circuit
Breakers
The wiring circuits in the vehicle are
protected from short circuits by a
combination of fuses and circuit
breakers. This greatly reduces the
chance of damage caused by
electrical problems.
{Danger
Fuses and circuit breakers are
marked with their ampere rating.
Do not exceed the
specified amperage rating when
replacing fuses and circuit
breakers. Use of an oversized
fuse or circuit breaker can result
in a vehicle fire. You and others
could be seriously injured or
killed.To check a fuse, look at the
silver-colored band inside the fuse.
If the band is broken or melted,
replace the fuse. Be sure to replace
a bad fuse with a new one of the
identical size and rating.
Fuses of the same amperage can
be temporarily borrowed from
another fuse location, if a fuse goes
out. Replace the fuse as soon as
possible.
To identify and check fuses, circuit
breakers, and relays, see
Engine
Compartment Fuse Block 0271,
Instrument Panel Fuse Block 0274,
and Rear Compartment Fuse Block
0 275.
Engine Compartment
Fuse Block
To remove the fuse block cover,
squeeze the clips on the cover and
lift it straight up. See Engine
Compartment Overview 0247.
Caution
Spilling liquid on any electrical
component on the vehicle may
damage it. Always keep the
covers on any electrical
component.
