6. Draw a vertical line (through the center
of each headlight beam pattern) and a
horizontal line (through the center of
each headlight beam pattern) on the
aiming screen measured from ground
to center mark on headlight lens.
7. Adjust the right side of each cut-off line
of the low beam to the horizontal line
with a phillips screwdriver - VERTICAL

REPLACEMENT OF LIGHT
BULBSG260A02L-GATBefore attempting to replace a light bulb,
be sure the switch is turned to the "OFF"
position.
The next paragraph shows how to reach
the light bulbs so they may be changed. Be
sure to replace the burned-out bulb with
one of the same number and wattage
rating.
See page 6-35 for the wattage descrip-
tions.
!
CAUTION:
o Keep the lights out of contact with
petroleum products, such as oil,
gasoline, etc.
o Be sure to replace the LED type
equipped bulbs with an assembly.
o After heavy, driving rain or washing,
headlight and taillight lenses could
appear frosty. This condition is
caused by the temperature difference
between the lamp inside and outside.
This is similar to the condensation on
your windows inside your vehicle
during the rain and doesn’t indicate a
problem with your vehicle. If the water
leaks into the lamp bulb circuitry, have
the vehicle checked by an Authorized
Hyundai Dealer.
