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) (Base
Level) 094 or
Driver Information Center (DIC) (Uplevel)
0 96.
Tachometer
The tachometer displays the engine speed in
revolutions per minute (rpm).
Fuel Gauge
Metric
English When the ignition is on, the fuel gauge
indicates about how much fuel is left in
the tank.
An arrow on the fuel gauge indicates the
side of the vehicle the fuel door is on.
When the indicator nears empty, the low
fuel light comes on. There is a small amount
of 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 gauge:
.At the service station, the fuel 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 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 gauge moves a little while turning a
corner or speeding up.
.The gauge takes a few seconds to
stabilize after the ignition is turned on,
and goes back to empty when the
ignition is turned off.

{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. SeeAirbag Readiness Light 086
for more information, including important
safety information.
Charging System Light
The charging system light comes on briefly
when the ignition is turned on, but the
engine is not running, as a check to show
the light is working. The light turns off
when the engine is started. If it does not,
have the vehicle serviced by your dealer. If the light 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.
When this light comes on, the Driver
Information Center (DIC) also displays a
message.
If a short distance must be driven with the
light on, be sure to turn off all accessories,
such as the radio and air conditioner.
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 and the engine is not
running. See
Ignition Positions 0186.
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 costly repairs not covered by the
vehicle warranty. This could also affect
the vehicle’s ability to pass an Emissions
Inspection/Maintenance test. See
Accessories and Modifications 0234.

88 Instruments and Controls
If the light is flashing :A malfunction has
been detected that could damage the
emission control system and increase vehicle
emissions. Diagnosis and service may be
required.
To help prevent damage, reduce vehicle
speed and avoid hard accelerations and
uphill grades. If towing a trailer, reduce the
amount of cargo being hauled as soon as
possible.
If the light continues to flash, find a safe
place to park. Turn the vehicle off and wait
at least 10 seconds before restarting the
engine. If the light is still flashing, follow
the previous guidelines and see your dealer
for service as soon as possible.
If the light is on steady : A malfunction has
been detected. Diagnosis and service may be
required.
Check the following:
.If fuel has been added to the vehicle
using the capless funnel adapter, make
sure that it has been removed. See
“Filling the Tank with a Portable Gas Can”
under Filling the Tank 0215. The
diagnostic system can detect if the
adapter has been left installed in the
vehicle, allowing fuel to evaporate into the atmosphere. A few driving trips with
the adapter removed may turn off the
light.
.Poor fuel quality can cause inefficient
engine operation and poor driveability,
which may go away once the engine is
warmed up. If this occurs, change the fuel
brand. It may require at least one full
tank of the proper fuel to turn the light
off. See
Recommended Fuel 0214.
If the light remains on, see your dealer.
Emissions Inspection and Maintenance
Programs
If the vehicle requires an Emissions
Inspection/Maintenance test, the test
equipment will likely connect to the
vehicle's Data Link Connector (DLC).
The DLC is under the instrument panel to
the left of the steering wheel. Connecting
devices that are not used to perform an
Emissions Inspection/Maintenance test or to service the vehicle may affect vehicle
operation. See
Add-On Electrical Equipment
0 232. See your dealer if assistance is
needed.
The vehicle may not pass inspection if:
.The light is on when the engine is
running.
.The light does not come on when the
ignition is on while the engine is off.
.Critical emission control systems have not
been completely diagnosed. If this
happens, the vehicle would not be ready
for inspection and might require
several days of routine driving before the
system is ready for inspection. This can
happen if the 12-volt battery has recently
been replaced or run down, or if the
vehicle has been recently serviced.
See your dealer if the vehicle will not pass
or cannot be made ready for the test.

When the Light Flashes First and Then Is On
Steady
If the light flashes for about a minute and
then stays on, there may be a problem with
the TPMS. If the problem is not corrected,
the light will come on at every ignition
cycle. See Tire Pressure Monitor Operation
0 274.
Engine Oil Pressure Light
Caution
Lack of proper engine oil maintenance
can damage the engine. Driving with the
engine oil low can also damage the
engine. The repairs would not be covered
by the vehicle warranty. Check the oil
level as soon as possible. Add oil if
required, but if the oil level is within the
operating range and the oil pressure is
still low, have the vehicle serviced.
Always follow the maintenance schedule
for changing engine oil.
This light should come on briefly as the
engine is started. If it does not come on,
have the vehicle serviced by your dealer.
If the light comes on and stays on, it means
that oil is not flowing through the engine
properly. The vehicle could be low on oil
and might have some other system
problem. See your dealer.
Low Fuel Warning Light (Base
Level)
English Shown
This light comes on for a few seconds when
the ignition is turned on as a check to
indicate it is working. If it does not come
on, have it fixed.
The low fuel warning light comes on and a
chime sounds when the vehicle is low on
fuel. The light turns off when fuel is added
to the fuel tank.
