Certain accessory power plugs may
not be compatible with the
accessory power outlet and could
overload vehicle or 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. SeeAdd-On
Electrical Equipment 0213.
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.
Warning Lights,
Gauges, and
Indicators
Warning lights and gauges can
signal that something is wrong
before it becomes serious enough
to cause an expensive repair or
replacement. Paying attention to the
warning lights and gauges could
prevent injury.
Some warning lights come on briefly
when the engine is started to
indicate they are working. When
one of the warning lights comes on
and stays on while driving, or when
one of the gauges shows there may
be a problem, check the section that
explains what to do. Waiting to do
repairs can be costly and even
dangerous.

110 Instruments and Controls
Speedometer
The speedometer shows the
vehicle's speed in either kilometers
per hour (km/h) or miles per
hour (mph).
Odometer
The odometer shows how far the
vehicle has been driven, in either
kilometers or miles.
Trip Odometer
The trip odometer shows how far
the vehicle has been driven since
the trip odometer was last reset.
The trip odometer is accessed and
reset through the Driver Information
Center (DIC). SeeDriver
Information Center (DIC) 0123.
Tachometer
The tachometer displays the engine
speed in revolutions per
minute (rpm).
Caution
If the engine is operated with the
rpm’s in the warning area at the
high end of the tachometer, the
vehicle could be damaged, and
the damage would not be covered
by the vehicle warranty. Do not
operate the engine with the rpm’s
in the warning area.
Fuel Gauge
When the ignition is on, the fuel
gauge shows how much fuel is left
in the fuel tank. When the indicator nears empty, a fuel warning light will
come on. See
Low Fuel Warning
Light 0120. The vehicle still has a
little fuel left, but the vehicle should
be fueled soon. An arrow on the fuel
gauge indicates the side of the
vehicle the fuel door is on.
Here are four things that some
owners ask about. These are
normal and do not indicate a
problem with the fuel gauge:
. At the service station, the gas
pump shuts off before the gauge
reads full.
. It takes a little more or less fuel
to fill up than the gauge
indicated. For example, the
gauge may have indicated the
fuel tank was half full, but it
actually took a little more or less
than half the fuel tank's capacity
to fill it.
. The indicator moves a little while
turning a corner or speeding up.
. The gauge goes back to empty
when the ignition is turned off.

112 Instruments and Controls
The airbag readiness light comes on
for several seconds when the
vehicle is started. If the light does
not come on then, have it fixed
immediately.
{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. SeePassenger
Sensing System 073 for important
safety information. The instrument
panel has a passenger airbag status
indicator.
United States
Canada
When the vehicle is started, the
passenger airbag status indicator
will light ON and OFF, or the symbol
for on and off, for several seconds
as a system check. Then, after
several seconds, the status
indicator will light either ON or OFF,
or the on or off symbol to let you
know the status of the front
outboard passenger frontal airbag
and knee airbag.
If the word ON or the on symbol is
lit on the passenger airbag status
indicator, it means that the front outboard passenger frontal airbag
and knee airbag are allowed to
inflate.
If the word OFF or the off symbol is
lit on the passenger airbag status
indicator, it means that the
passenger sensing system has
turned off the front outboard
passenger frontal airbag and knee
airbag.
If, after several seconds, both status
indicator lights remain on, or if there
are no lights at all, there may be a
problem with the lights or the
passenger sensing system. See
your dealer for service.
{Warning
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right
away. See
Airbag Readiness

information.
Charging System Light
This light will come on briefly when
the ignition is turned on, and the
engine is not running, as a check to
show it is working.
It should go out when the engine is
started. If it stays on, or comes on
while driving, there may be a
problem with the electrical charging
system. Have it checked by your
dealer. Driving while this light is on
could drain the battery. If a short
distance must be driven with the
light on, turn off all accessories, such as the radio and air
conditioner, to help reduce the drain
on the battery.
Malfunction Indicator
Lamp (Check Engine
Light)
This light is part of the vehicle’s
emission control on-board
diagnostic system. If this light is on
while the engine is running, a
malfunction has been detected and
the vehicle may require service. The
light should come on to show that it
is working when the ignition is on
with the engine not running for Key
Access or in Service Mode for
Keyless Access.
See
Ignition Positions (Key Access)
0 181 orIgnition Positions (Keyless
Access) 0183.
Malfunctions are often indicated by
the system before any problem is
noticeable. Being aware of the light
and seeking service promptly when
it comes on may prevent damage.
Caution
If the vehicle is driven continually
with this light on, the emission
control system may not work as
well, the fuel economy may be
lower, and the vehicle may not
run smoothly. This could lead to
costly repairs that might not be
covered by the vehicle warranty.
Caution
Modifications to the engine,
transmission, exhaust, intake,
or fuel system, or the use of
replacement tires that do not
meet the original tire
specifications, can cause this light
to come on. This could lead to
