3. Run the engine until it reaches normal operating temperature.
4. Allow the engine to idle for at least one minute.
5. Turn the A/C on and allow the engine to idle for at least one minute.
6. Release the parking brake. With your foot on the brake pedal and with
the A/C on, put the vehicle in D (Drive) and allow the engine to idle for
at least one minute.
Note:If you do not allow the engine to relearn its idle trim, the idle
quality of your vehicle may be adversely affected until the idle trim is
eventually relearned.
7. Drive the vehicle to complete the relearning process.
•The vehicle may need to be driven 10 miles (16 kilometers) or more
to relearn the idle and fuel trim strategy along with the ethanol
content for flexible fuel vehicles.
•For flexible fuel vehicles, if you are operating on E85, you may
experience poor starts or an inability to start the engine and
driveability problems until the fuel trim and ethanol content have been
relearned.
If the battery has been disconnected or a new battery has been installed,
the clock and radio settings must be reset once the battery is
reconnected.
•Always dispose of automotive
batteries in a responsible manner.
Follow your local authorized
standards for disposal. Call your
local authorized recycling center
to find out more about recycling
automotive batteries.

4. On the wall or screen you will
observe a light pattern with a
distinct horizontal edge towards the
right. If this edge is not at the
horizontal reference line, the beam
will need to be adjusted so the edge
is at the same height as the
horizontal reference line.
5. Locate the vertical adjuster on
each headlamp. Use a number 2
Phillips screwdriver to turn the
adjuster either counterclockwise or
clockwise in order to adjust the
vertical aim of the headlamp. The
upper edge of the light pattern
should touch the horizontal
reference line.
6. Repeat Steps 3–5 for the other
headlamp.
7. Close the hood and turn off the lamps.
HORIZONTAL AIM IS NOT REQUIRED FOR THIS VEHICLE AND IS
NOT ADJUSTABLE.
CHANGING A BULB
Lamp Assembly Condensation
Exterior lamps are vented to accommodate normal changes in pressure.
Condensation can be a natural by-product of this design. When moist air
enters the lamp assembly through the vents, there is a possibility that
condensation can occur when the temperature is cold. When normal
condensation occurs, a thin film of mist can form on the interior of the
lens. The thin mist eventually clears and exits through the vents during
normal operation. Clearing time may take as long as 48 hours under dry
weather conditions.
These are examples of acceptable condensation:
•Presence of thin mist (no streaks, drip marks or droplets).
•Fine mist covers less than 50% of the lens.

WARNING:Handle a halogen headlamp bulb carefully and keep
out of children’s reach. Grasp the bulb only by its plastic base
and do not touch the glass. The oil from your hand could cause the
bulb to break the next time the headlamps are operated.
Install the new bulb(s) in reverse order.

BULB SPECIFICATION CHART
Replacement bulbs are specified in the chart below. Headlamp bulbs
must be marked with an authorized “D.O.T.” for North America and an
“E” for Europe to ensure lamp performance, light brightness and pattern
and safe visibility. The correct bulbs will not damage the lamp assembly
or void the lamp assembly warranty and will provide quality bulb
illumination time.

Performing the System Reset Procedure
Read the entire procedure before attempting.
1. Drive the vehicle above 20 mph (32 km/h) for at least two minutes
and then park in a safe location where you can easily get to all four tires
and have access to an air pump.
2. Place the ignition in the off position and keep the key in the ignition.
3. Cycle the ignition to the on position with the engine off.
4. Turn the hazard flashers on then off three times. This must be
accomplished within 10 seconds.
If the reset mode has been entered successfully, the horn will sound
once, the system indicator will flash and a message is shown in the
information display (if equipped). If this does not occur, please try again
startingatStep2.
If after repeated attempts to enter the reset mode, the horn does not
sound, the system indicator does not flash and no message is shown in the
information display (if equipped), seek service from your authorized dealer.
5.Note:Train the tire pressure monitoring system sensors in the tires
using the following system reset sequence starting with the left front tire
in the following clockwise order:
•Left front (Driver’s side front tire)
•Right front (Passenger’s side front tire)
•Right rear (Passenger’s side rear tire)
•Left rear (Driver’s side rear tire)
6. Remove the valve cap from the valve stem on the left front tire;
decrease the air pressure until the horn sounds.
Note:The single horn chirp confirms that the sensor identification code
has been learned by the module for this position. If a double horn is
heard, the reset procedure was unsuccessful, and must be repeated.
7. Remove the valve cap from the valve stem on the right front tire;
decrease the air pressure until the horn sounds.
8. Remove the valve cap from the valve stem on the right rear tire;
decrease the air pressure until the horn sounds.
9. Remove the valve cap from the valve stem on the left rear tire;
decrease the air pressure until the horn sounds.
Training is complete after the horn sounds for the last tire trained
(driver’s side rear tire), the system indicator stops flashing, and a
message is shown in the information display (if equipped).

Note:If equipped with a tether, perform the following steps:
6. Lift the spare tire on end to
access the tether attachment.
7. Use the lug wrench to remove
the lug nut from the spare tire
tether.
8. If not replacing the spare or flat
tire to the underbody storage area,
raise the wheel retainer up into the
installed position.
9. Use the attached fastener strap (on the spare tire tether) to attach
the tether end to the winch retainer prior to raising to the installed
position.
