Daytime Running Lights Control Unit Input Test (Canadal
1.Remove the driver's dashboard lower cover and the
knee bolstet (see section 20).
Disconnect the connectors from the daytime run-
ning lights control unit.
Inspect the connector and socket terminals to be
sure they are all making good contact.
lf the terminals are bent, loose or corroded, repair
them as necessary, and recheck the system.
lf the terminals look OK, make the tollowing
inout tests at the connector'
- lf anv test indicates a problem, find and correct
the cause, then recheck the system.
- lf all the input tests prove OK, the control unrt

Adjustment
Bstore adiusting the headlights:
. Park the vehicle on level ground
. Make sure the fuel tank is tull
. The driver or someone who weighs the same should
sit in the driver's seat.
. Load the trunk with the items you usually carry'
. Push down on the front and rear bumpers several
times to make sure the vehicle is sitting normally'
CAUTION: Halogen headlights become very hot in use;
do not touch them or the atiaching hardware immedi-
ately after they have been turned off.
1. ODen the hood.
2. Remove the left inner fender {see section 20).
3. Checkthe horizontal adjustment indicator.
The "0" mark on the horizontal indicator gear should
be aligned with the mark.
"0" MARK
Check the vertical adjustment indicator. The bubble
should be centered underneath the longest scribe
mark on the gauge.

)
5.lf either indicator is not aligned with its "0" mark as
described left column, an adjustment can be made
by using a Phillips screwdriver.
Adjust the headlights to local requirements by turn-
ing the adjusters.
NOTE:
. As the outer lenses are made of an acrylicoated,
polycarbonated material, do not cover the head-
lights when they are turned on
. When making horizontal adiustments, slide the
horizontal indicator gear rearward.
After horizontal adjustment, put back the hori-
zontal indicator gear.
