Dual Batteries (If Equipped)
Your vehicle may be equipped with a frame-mounted battery located on
the passenger side frame rail, behind the front passenger door. This
battery is connected in parallel with the battery in the engine
compartment. Both batteries are used to start the vehicle.
Because your vehicle’s engine is electronically controlled by a computer,
some control conditions are maintained by power from the battery. When
the battery is disconnected or a new battery is installed, the engine must
relearn its idle and fuel trim strategy for optimum driveability and
performance. Flexible fuel vehicles (FFV) must also relearn the ethanol
content of the fuel for optimum driveability and performance. To begin
this process:
1. With the vehicle at a complete stop, set the parking brake.
2. Put the gearshift in P (Park), turn off all accessories and start the
engine.
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.
7. Drive the vehicle to complete the relearning process.
•The vehicle may need to be driven 10 miles (16 km) or more to
relearn the idle and fuel trim strategy along with the ethanol content
for flexible fuel vehicles.
•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.
•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.

Vertical and Horizontal Aim Adjustment (Sealed Beam Headlamps)
The headlamps on your vehicle are intended to be aimed using
mechanical aimers. If mechanical aimers are used and the cross-car sight
line is in any way blocked, set the legs of the universal adaptor all to the
same setting, such that the cross-car sight line is no longer blocked, per
the instructions for the brand of mechanical aimer used. You can also
aim the headlamps visually using the procedure below.
To adjust the headlamps:
1. Park your vehicle on a level surface about 25 feet (7.6 meters) away
from a vertical plain surface. Check your headlamp alignment at night or
in a dark area so that you can see the headlamp beam pattern.
•(A) 8 feet (2.4 meters)
•(B) Center height of lamp to
ground
•(C) 25 feet (7.6 meters)
•(D) Horizontal reference line
•(E) Vertical reference line for the
center of the headlamp
•(F) Vertical reference line for the
center of the vehicle
2. The center of the headlamp is marked either on the lens (a circle or
cross marker) or on the bulb shield, internal to the lamp (mark or
feature). Measure the height from the center of your headlamp to the
ground (B) and mark an 8 foot (2.4 meter) long horizontal line on the
wall or screen (D) at this height (masking tape works well).
3. Turn on the low beam headlamps
and open the hood.
4. Locate the high intensity area of
the beam pattern and place the top
edge of the intensity zone even with
the horizontal reference line (D). If
the top edge of the high intensity
area is not even with the horizontal
line, follow the next step to adjust
it.

5. Locate the vertical adjuster (A)
for each headlamp. Turn the
adjuster control either clockwise or
counterclockwise to adjust the
vertical aim of the headlamp.
6. In addition to the horizontal line
marked in step 2, a pair of vertical
lines (E) must be marked at the
center line of the headlamps on the
wall or screen.
7. On the wall or screen, locate the high intensity area of the beam
pattern. The left edge of the high intensity area should be even with the
vertical line corresponding to the headlamp under adjustment. If the left
edge of the high intensity area is not even with the vertical line, follow
the next step to adjust it.
8. Locate the horizontal adjuster (B) for each headlamp. Turn it
clockwise or counterclockwise to place the left edge of the high intensity
area even with the vertical line corresponding to the headlamp under
adjustment.
Vertical Aim Adjustment (Aerodynamic Headlamps)
The headlamps on your vehicle can only be vertically adjusted. Your
vehicle does not require horizontal aim adjustments.
To adjust the headlamps:
1. Park the vehicle directly in front of a wall or screen on a level surface,
approximately 25 feet (7.6 meters) away.A

•(A) 8 feet (2.4 meters)
•(B) Center height of lamp to
ground
•(C) 25 feet (7.6 meters)
•(D) Horizontal reference line
2. Measure the height from the
center of your headlamp (indicated
by a 3.0 millimeter circle on the
lens) to the ground and mark an
8 foot (2.4 meter) horizontal
reference line on the vertical wall or screen at this height (a piece of
masking tape works well).
3. Turn on the low beam headlamps to illuminate the wall or screen and
open the hood. Cover one of the headlamps so no light hits the wall.
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
the back of each headlamp, then
use a long Phillips #2 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 align with
the horizontal reference line.
6. Repeat step 3–5 for the other
headlamp.
7. Close the hood and turn off the lamps.
