CAUTION

Do not cover a headlight for more than three minutes to 
prevent the plastic headlight lens deformation.
NOTE: High-beam pattern should be correct when the 
low-beams are adjusted properly.

LUMINOUS INTENSITY MEASUREMENT

M1540100600129

1. Set the headlights to high-beam.
2. Using a photometer, and following its manufacturer's 

instruction manual, measure the headlight center intensity 
and check to be sure that the limit value is satisfied.

Limit: 40,000 cd or more {When a screen is set 18.3m 
(60 feet) ahead of the vehicle}

NOTE: When measuring the intensity, maintain an engine 
speed of 2,000 r/min, with the battery fully charged.
There may be special local regulations pertaining to headlight 
intensity. Be sure to make any adjustments necessary to satisfy 
such regulations.
If an illuminometer is used to make the measurements, convert 
its values to photometer values by using the following formula.

I =E 

×  r

2

• I = intensity (cd)

• E = illumination (lux)

• r = distance (m) from headlights to illuminometer

HEADLIGHT BULB (LOW-BEAM) REPLACEMENT 
<VEHICLES WITHOUT DISCHARGE HEADLIGHT>

CAUTION

Do not touch the bulb surface with bare hands or dirty 
gloves. If the bulb surface (glass part) gets dirty, immedi-
ately clean it with alcohol or thinner. After drying com-
pletely, install the bulb.
1. When replacing the right bulb, lift the radiator condenser 

tank upward, and remove it. When replacing the left bulb, 
remove the relay box.

2. Disconnect the connector, and twist the headlight bulb 

(low-beam) to remove.
