.Check that good quality fuel is
used. Poor fuel quality causes
the engine not to run as
efficiently as designed and may
cause stalling after start-up,
stalling when the vehicle is
changed into gear, misfiring,
hesitation on acceleration,
or stumbling on acceleration.
These conditions might go away
once the engine is warmed up.
If one or more of these conditions
occurs, change the fuel brand used.
It may require at least one full tank
of the proper fuel to turn the light off.
See Fuel on page 9-54.
If none of the above have made the
light turn off, your dealer can check
the vehicle. The dealer has the
proper test equipment and
diagnostic tools to fix any
mechanical or electrical problems
that might have developed.Emissions Inspection and
Maintenance Programs
Depending on where you live, your
vehicle may be required to
participate in an emission control
system inspection and maintenance
program. For the inspection, the
emission system test equipment will
likely connect to the vehicle's Data
Link Connector (DLC).
The DLC is under the instrument
panel next to the steering wheel.
See your dealer if assistance is
needed.
The vehicle may not pass
inspection if:
.The malfunction indicator lamp is
on while the engine is running,
or the malfunction indicator lamp is not on while the vehicle is in
ON/RUN or Service Only Mode.
See your dealer for assistance in
verifying proper operation of the
malfunction indicator lamp.
.The OBD II (On-Board
Diagnostics) system determines
that critical emission control
systems have not been
completely diagnosed by the
system. If this were to occur, the
vehicle would be considered not
ready for inspection. This can
happen if the 12-volt battery has
recently been replaced or
run down.
The diagnostic system is
designed to evaluate critical
emission control systems during
normal driving. This can take
several days of driving. If this
has been done and the vehicle
still does not pass the inspection
for lack of OBD II system
readiness, your dealer can
prepare the vehicle for
inspection.

vehicle is low on fuel. The fuel
range estimate is based on an
average of the vehicle's fuel
economy over recent driving history
and the amount of fuel remaining in
the fuel tank.
Average Speed:Displays the
average speed of the vehicle in
kilometers per hour (km/h) or miles
per hour (mph). This average is

the oil's remaining useful life.
If REMAINING OIL LIFE 99% is
displayed, that means 99% of the
current oil life remains.
When the remaining oil life is low,
the CHANGE ENGINE OIL SOON
message will appear on the display.
See Engine Oil Messages on
page 5-31. The oil should be
changed as soon as possible. See
Engine Oil on page 10-8. In addition
to the engine oil life system
monitoring the oil life, additional
maintenance is recommended in the
Maintenance Schedule. See
Maintenance Schedule on
page 11-2.
The Oil Life display must be reset
after each oil change. It will not
reset itself. Do not reset the Oil Life
display 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,
press and hold

the coolant temperature in either
degrees Celsius (°C) or degrees
Fahrenheit (°F).
Tire Pressure: Displays the
approximate pressures of all four
tires. Tire pressure is displayed in
either kilopascal (kPa) or in pounds
per square inch (psi). If the pressure
is low, the value for that tire is
shown in amber. See Tire Pressure
Monitor System on page 10-46 and
Tire Pressure Monitor Operation on
page 10-47.
Battery Voltage: Displays the
current battery voltage. The battery
voltage can fluctuate while viewing
this information on the DIC. This is
normal.
Speed Signs: Displays sign
information, which comes from a
roadway database in the onboard
navigation.

To program a garage door opener,
park outside directly in line with and
facing the garage door opener
receiver. Clear all people and
objects near the garage door.
Make sure the hand-held transmitter
has a new battery for quick and
accurate transmission of the
radio-frequency signal.
Programming the Universal
Remote System
For questions or help programming
the Universal Remote system, call
1-800-355-3515 or see
www.homelink.com.
Programming involves
time-sensitive actions, and may time
out causing the procedure to be
repeated.
To program up to three devices:
1. Hold the end of the hand-heldtransmitter about 3 to 8 cm (1 to
3 in) away from the Universal
Remote system buttons with the
indicator light in view. The hand-held transmitter was
supplied by the manufacturer of
the garage door opener receiver.
2. At the same time, press and hold both the hand-held
transmitter button and one of the
three Universal Remote system
buttons to be used to operate
the garage door. Do not release
either button until the indicator
light changes from a slow to a
rapid flash. Then release both
buttons.
Some garage door openers may
require substitution of Step 2
with the procedure under in
“Radio Signals for Canada and
Some Gate Operators” later in
this section.
3. Press and hold the newly programmed Universal Remote
system button for five seconds
while watching the indicator light
and garage door activation.
.If the indicator light stays on
continuously or the garage
door moves when the button is pressed, then
programming is complete.
There is no need to
complete Steps 4–6.
.If the indicator light does
not come on or the garage
door does not move, a
second button press may
be required. For a second
time, press and hold the
newly programmed button
for five seconds. If the light
stays on or the garage door
moves, programming is
complete.
.If the indicator light blinks
rapidly for two seconds,
then changes to a solid light
and the garage door does
not move, continue with
programming Steps 4–6.
