Power Outlets
The accessory power outlets can be
used to connect electrical
equipment, such as a cellular
phone.
There are two accessory power
outlets, one is located inside the
center console storage and other on
the rear of the center floor console.
Open the protective cover to use the
accessory power outlet.
Certain electrical accessories may
not be compatible with the
accessory power outlets and could
result in blown vehicle or adapter
fuses. If you experience a problem,
see your dealer/retailer for
additional information on the
accessory power outlet.
Notice: Adding any electrical
equipment to the vehicle can
damage it or keep other
components from working as
they should. The repairs would not be covered by the vehicle
warranty. Do not use equipment
exceeding maximum amperage
rating of 20 amperes. Check with
your dealer/retailer before adding
electrical equipment.
When adding electrical equipment,
be sure to follow the installation
instructions included with the
equipment.
Notice:
Improper use of the
power outlet can cause damage
not covered by the vehicle
warranty. Do not hang any type of
accessory or accessory bracket
from the plug because the power
outlets are designed for
accessory power plugs only.
Power Outlet 120 Volt Alternating
Current
The vehicle may have a power
outlet that can be used to plug in
electrical equipment that uses a
maximum limit of 150 watts.

Instruments and Controls 4-11
The power outlet is located 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 in
ON/RUN and equipment requiring
less than 150 watts is plugged into
the outlet, and no system fault is
detected.
The indicator light does not come on
when the ignition is in LOCK/OFF or
if no equipment is plugged into the
outlet.If you try to connect equipment
using more than 150 watts or a
system fault is detected, the
equipment may operate for a short
period and turn itself off.
A protection circuit shuts off the
power supply and the indicator light
turns off. To reset the circuit, unplug
the item and plug it back in or turn
the Remote Accessory Power (RAP)
off and then back on. See
Retained
Accessory Power (RAP)
on
page 8‑20. Prolonged usage of the
power outlet at the maximum load of
150 watts, may cause the outlet to
overheat and automatically
shutdown. The power restarts when
equipment that operates within the
limit is plugged into the outlet and a
system fault is not detected. The power outlet is not designed for
the following electrical equipment
and may not work properly if these
items are plugged into the power
outlet:
.Equipment with high initial peak
wattage such as:
compressor-driven refrigerators
and electric power tools.
.Other equipment requiring an
extremely stable power supply
such as:
microcomputer-controlled
electric blankets, touch sensor
lamps, etc.

4-12 Instruments and Controls
Warning Lights,
Gages, and Indicators
Warning lights come on when there
could be a problem with a vehicle
function. Some warning lights come
on briefly when the engine is started
to indicate they are working.
Gages can indicate when there
could be a problem with a vehicle
function. Often gages and warning
lights work together to indicate a
problem with the vehicle.
When one of the warning lights
comes on and stays on while
driving, or when one of the gages
shows there may be a problem,
check the section that explains what
to do. Follow this manual's advice.
Waiting to do repairs can be costly
and even dangerous.

Instruments and Controls 4-13
Instrument Cluster

4-14 Instruments and Controls
Speedometer
The speedometer shows the
vehicle's speed in both kilometers
per hour (km/h) and miles per
hour (mph).
Odometer
The odometer shows how far the
vehicle has been driven, in either
kilometers or miles.
This vehicle has a tamper-resistant
odometer. If the vehicle needs a
new odometer installed, the new
one is set to the mileage of the old
odometer. If this is not possible, it is
set at zero and a label is put on the
driver's door to show the old
mileage reading.
Tachometer
The tachometer displays the engine
speed in revolutions per
minute (rpm).
Fuel Gage
When the ignition is on, the fuel
gage indicates about how much fuel
is left in the tank.
An arrow on the fuel gage indicates
the side of the vehicle the fuel door
is on.
When the indicator nears empty, the
low fuel light comes on. There is still
a little fuel left, but the fuel tank
should be filled soon.Here are four things that some
owners ask about. None of these
show a problem with the fuel gage:
.At the service station, the fuel
pump shuts off before the gage
reads full.
.It takes a little more or less fuel
to fill up than the gage indicated.
For example, the gage indicated
the tank was half full, but it
actually took a little more or less
than half the tank's capacity to
fill the tank.
.The gage moves a little while
turning a corner or speeding up.
.The gage takes a few seconds
to stabilize after the ignition is
turned on, and goes back to
empty when the ignition is
turned off.

Instruments and Controls 4-15
Engine Coolant
Temperature Gage
This gage shows the engine coolant
temperature.
If the gage pointer moves towards
the shaded area, the engine is
too hot.
This reading indicates the same
thing as the warning light. It means
that the engine coolant has
overheated. If the vehicle has been
operating under normal driving
conditions, pull off the road, stop thevehicle, and turn off the engine as
soon as possible. See
Engine
Overheating
on page 9‑20for more
information.
Safety Belt Reminders
Driver Safety Belt Reminder
Light
There is a driver safety belt
reminder light on the instrument
panel cluster.
When the vehicle is started this light
flashes and a chime may come on
to remind drivers to fasten their
safety belts. Then the light stays on
solid until the belt is buckled. This
cycle may continue several times if
the driver remains or becomes
unbuckled while the vehicle is
moving. If the driver safety belt is buckled,
neither the light nor chime come on.
Passenger Safety Belt
Reminder Light
When the vehicle is started this light
flashes and a chime comes on to
remind passengers to fasten their
safety belt. Then the light stays on
solid until the belt is buckled. This
cycle continues several times if the
passenger remains or becomes
unbuckled while the vehicle is
moving.
If the passenger safety belt is
buckled, neither the chime nor the
light comes on.
The front passenger safety belt
warning light and chime may turn on
if an object is put on the seat such
as a briefcase, handbag, grocery

4-16 Instruments and Controls
bag, laptop or other electronic
device. To turn off the warning light
and or chime, remove the object
from the seat or buckle the
safety belt
Airbag Readiness Light
This light shows if there is an
electrical problem. The system
check includes the airbag sensor,
the pretensioners, the airbag
modules, the wiring and the crash
sensing and diagnostic module.
For more information on the airbag
system, seeAirbag System
on
page 2‑24.
The airbag readiness light comes on
solid and stays on for several
seconds when the vehicle is started.
Then the light goes out. If it stays on solid after the vehicle
has been started or comes on while
driving, the airbag system may not
work properly. Have the vehicle
serviced right away.
{WARNING
If the airbag readiness light stays
on after the vehicle is started or
comes on while driving, it means
the airbag system might not be
working properly. The airbags in
the vehicle might not inflate in a
crash, or they could even inflate
without a crash. To help avoid
injury, have the vehicle serviced
right away.
Passenger Airbag Status
Indicator
The vehicle has a passenger
sensing system. See
Passenger
Sensing System
on page 2‑32for
important safety information. The
instrument panel has a passenger
airbag status indicator.
When the vehicle is started, the
passenger airbag status indicator
will light the words ON and OFF for
several seconds as a system check.
If you are using remote start,
if equipped, to start the vehicle from
a distance you may not see the
system check. Then, after several
more seconds, the status indicator
will light either the word ON or OFF
to let you know the status of the
right front passenger frontal airbag.
If the word ON is lit on the
passenger airbag status indicator,
it means that the right front
passenger frontal airbag is enabled
(may inflate).
