Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
might begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a vehicle
registration.
Here are some things you need to know to help your
vehicle pass an inspection:
Your vehicle will not pass this inspection if the check
engine light is on or not working properly.
Your vehicle will not pass this inspection if the OBD
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen if
you have recently replaced the battery or if the battery
has run down. The diagnostic system is designed to
evaluate critical emission control systems during normal
driving. This can take several days of routine driving. If
you have done this and your vehicle still does not pass
the inspection for lack of OBD system readiness, your
dealer/retailer can prepare the vehicle for inspection.
Oil Pressure Light
{CAUTION:
Do not keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Lack of proper engine oil maintenance may
damage the engine. The repairs would not be covered
by your warranty. Always follow the maintenance
schedule in this manual for changing engine oil.
This light will come on
briey when you start
your engine. If it does
not, have your vehicle
serviced.

When the light comes on and stays on, it means that oil is
not owing through your engine properly. You could be
low on oil and you might have some other system
problem.

Fuel Gage
When the indicator nears empty, you still have a little
fuel left, but you should get more soon.
Your fuel gage tells you about how much fuel you have
left when the ignition is on.Here are four things some owners ask about. All these
things are normal and do not indicate that anything
is wrong with the fuel gage.
At the gas station, the gas pump shuts off before
the gage reads full.
It takes a little more (or less) fuel to ll up than the
gage reads. For example, the gage read half full,
but it took more (or less) than half of the tank’s
capacity to ll it.
The gage pointer may move while cornering,
braking or speeding up.
The gage may not indicate empty when the ignition
is turned off.
Low Fuel Warning Light
The light next to the fuel gage will come on briey when
you are starting the engine.
This light comes on when the fuel tank is low on fuel.
To turn it off, add fuel to the fuel tank. United States

Oil Life
Press the information button until OIL LIFE displays.
This mode shows an estimate of the oil’s remaining
useful life. If you see OIL LIFE 99% on the display, that
means 99% of the current oil life remains. The engine
oil life system will alert you to change the oil on a
schedule consistent with your driving conditions.
When the remaining oil life is low, the CHANGE OIL
SOON message will appear on the display. You should
change the oil as soon as possible. SeeEngine Oil on
page 5-13. In addition to the engine oil life system
monitoring the oil life, additional maintenance is
recommended in the Maintenance Schedule in this
manual. SeeScheduled Maintenance on page 6-4
for more information.
Remember, you must reset the OIL LIFE yourself
after each oil change. It will not reset itself. Also,
be careful not to reset the OIL LIFE accidentally at any
time other than when the oil has just been changed.
It cannot be reset accurately until the next oil change.
To reset the engine oil life system, seeEngine Oil
Life System on page 5-16. The display will show 100%
when the system is reset.
Tire Pressure
Press the information button until FRONT TIRE
PRESSURE displays. This mode shows the pressure
for the front tires. To view the pressure for the rear tires,
press the information button again until REAR TIRE
PRESSURE displays. The tire pressure will be shown in
either pounds per square inch (psi) or kilopascals (kPa).
If a low tire pressure condition is detected by the system
while driving, a message advising you to check the
pressure in a specic tire will appear in the display.
The tire pressure light will also ash and then remain
on during the same ignition cycle. SeeInflation - Tire
Pressure on page 5-54andDIC Warnings and Messages
on page 3-58for more information.
If the tire pressure display shows dashes or blanks
instead of a value, there may be a problem with your
vehicle. If this consistently occurs, see your dealer
for service.

Compass Calibration
The compass can be manually calibrated. Only calibrate
the compass in a magnetically clean and safe location,
such as an open parking lot, where driving the vehicle
in circles is not a danger. It is suggested to calibrate
away from tall buildings, utility wires, manhole covers,
or other industrial structures, if possible.
If CAL should ever appear in the DIC display, the
compass should be calibrated.
If the DIC display does not show a heading, for example,
N for North, or the heading does not change after
making turns, there may be a strong magnetic eld
interfering with the compass. Such interference may
be caused by a magnetic CB or cell phone antenna
mount, a magnetic emergency light, magnetic note
pad holder, or any other magnetic item. Turn off
the vehicle, move the magnetic item, then turn on
the vehicle and calibrate the compass.To calibrate the compass, use the following procedure:Compass Calibration Procedure
1. Before calibrating the compass, make sure the
compass zone is set to the variance zone in
which the vehicle is located. See “Compass
Variance (Zone) Procedure” earlier in this section.
Do not operate any switches such as window,
sunroof, climate controls, seats, etc. during
the calibration procedure.
2. Press the menu button until COMPASS
CALIBRATION displays.
3. Press the set/reset button to start the compass
calibration.
4. The DIC will display CALIBRATION BEGUN DRIVE
UNTIL DONE. Drive the vehicle in tight circles at
less than 5 mph (8 km/h) to complete the calibration.
The DIC will display CALIBRATION FINISHED
for a few seconds when the calibration is complete.
