- Place vehicle and screen on level surface.
- Ensure there is no load in vehicle other than the driver (or equivalent weight placed in driver's position).
Coolant and engine oil filled to correct level, and fuel tank full.
- Confirm spare tire, jack and tools are properly stowed.
- Aim each headlamp individually and ensure other headlamp beam pattern is blocked from screen.
- Use adjusting screw to perform aiming adjustment
NOTE:
Basic illuminating area for adjustment should be within the range shown on the aiming chart. Adjust head-
lamps accordingly.
LOW BEAM AND HIGH BEAM
1. Turn headlamp low beam on.
2. Use adjusting screw to perform aiming adjustment.
Bulb ReplacementINFOID:0000000003533350
CAUTION:
• Disconnect battery negative terminal before touching xenon bulb or headlamp wiring harness
assembly.
• Turn headlamp switch OFF before disconnecting headlamp harness connector.
• Do not touch bulb by hand right after being turned off. Burning may result.
• Do not touch the glass of bulb directly by hand. Keep grease and other oily substances away from it.
• Do not turn xenon bulb ON when xenon bulb is removed from front combination lamp assembly.
• After installing the bulb, be sure to install the bulb socket securely to ensure watertightness.
