Power Outlets
Power Outlets 12-Volt Direct
Current
The 12-volt power outlets can be
used to plug in electrical equipment,
such as a cell phone or MP3 player.
The vehicle has three power outlets:
.
Under the front of the center
console.
.
Inside the center console
storage.
.
On the rear of the center
console.
Open the protective cover to use the
power outlet.
The outlet is powered when the
ignition is in ON/RUN or ACC/
ACCESSORY, or until the driver
door is opened within 10 minutes of
turning off the vehicle. See
Retained
Accessory Power (RAP)
0

.
Certain electrical accessories may
not be compatible with the
accessory power outlet and could
overload vehicle or adapter fuses.
If there is a problem, see your
dealer.
When adding electrical equipment,
be sure to follow the installation
instructions included with the
equipment. See
Add-On Electrical
Equipment

.
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
The vehicle may have a power
outlet that can be used to plug in
electrical equipment with a
maximum limit of 150 watts.

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
might be burned out.
Have any burned out bulbs
replaced. If the bulb is not burned
out, check the fuse. See

Fog Lamps
The fog lamps button is on the
instrument panel to left of the
steering wheel.
To turn on the fog lamps, the ignition
and the headlamps or parking lamps
must be on.
If the fog lamps are turned on while
the exterior lamp control is in the
AUTO position, the headlamps
come on automatically.

Driving and Operating
.
The outside temperature is not
in the required operating range,
typically below
10 °C (14 °F) or
above 50 °C (122 °F).
.
The transmission is in any gear
other than D (Drive).
.
The battery is low.
.
The battery has been
disconnected.
.
The interior comfort level has not
reached the required level for
the climate control system or
defog settings. See

.
.
The Auto Stop time is greater
than two minutes.
Engine Heater
The engine coolant heater,
if available, can help in cold weather
conditions at or below
18 °C (0 °F)
for easier starting and better fuel
economy during engine warm-up.
Plug in the coolant heater at least
four hours before starting the
vehicle. An internal thermostat in
the plug end of the cord will prevent
engine coolant heater operation at
temperatures above
18 °C (0 °F).
To Use the Engine Coolant
Heater
1.
Turn off the engine.
2.
Open the hood and unwrap the
electrical cord.
The electrical cord is on the
driver side of the engine
compartment, between the
fender and the engine
compartment fuse block.
Check the heater cord for
damage. If it is damaged, do
not use it. See your dealer for
a replacement. Inspect the
cord for damage yearly.
3.
Plug it into a normal, grounded
110-volt AC outlet.
{
Warning
Improper use of the heater cord
or an extension cord can damage
the cord and may result in
overheating and fire.
.
Plug the cord into a
three-prong electrical utility
receptacle that is protected
by a ground fault detection
function. An ungrounded
outlet could cause an
electric shock.
.
Use a weatherproof,
heavy-duty, 15 amp-rated
extension cord if needed.

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
0
232
.
.
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
0
229
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.

Electrical System
Electrical System
Overload
The vehicle has fuses and circuit
breakers to protect against an
electrical system overload.
When the current electrical load 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.
Fuses and circuit breakers protect
power devices in the vehicle.
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.
248
Vehicle Care
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.
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
