Headlight AdjustmentfCheck tire pressure and adjust if necessary.
fPlease see the chapter “TIRE PRESSURES, 
COLD (68 °F/20 °C)” on Page 354.
fPlease see the chapter “REPLACING BULBS” 
on Page 326.Adjustment
The adjustment is made with the vehicle ready to 
drive and the fuel tank completely filled.
T h e  d r i ve r ' s  s e a t  m u s t  b e  l o a d e d  b y  a  p e r s o n  o r  a  
165lbs. (75kg) weight and the tire pressures must 
meet the prescribed values. After being loaded, 
the car must be rolled a few meters so that the 
suspension can settle.
For checking the headlight adjustment, the verti-
cal position of the cutoff of the lowbeam (see fig.) 
has to be projected on a vertical screen (wall) in 
distance of 24.6 ft. (7.5 m) from the front lens of 
the headlamp.The correct position of the cutoff is 
3.0 in. (7.5 cm) at 24.6 ft. or 7.5 m (0.4°) below 
a horizontal line, x cm from ground to the center 
of the headlamp lens.
Lateral adjustment of the headlights should be 
carried out at a specialist workshop with an optical 
adjustment unit.
Distance
Visual aim shall be performed at not less than 
24.6 ft. (7.5 m) (this value is a rounded down con-
version from the 25-foot distance typical of field 
aim using a screen). The 24.6 ft. (7.5 m) distance 
is measured from the headlamp lens to the 
viewing screen.
Floor
The surface upon which the vehicle rests is flat 
and approximately level.
Screen
The screen upon which headlamp beams are pro-
jected is perpendicular to the floor and the 
vehicle's longitudinal axis, flat, uniformly light in 
color, unobstructed, and wide and high enough to 
accommodate the vehicle beam patterns to be 
aimed. 
The screen should be wide enough to provide at 
least 3.3 ft. (1 m) of space outboard of the 
vehicle's headlamp spacing.

Changing headlights from left to 
right-hand trafficIf you travel to a country where traffic uses the 
other side of the road, the headlights must be 
repositioned when you cross the border. The low 
beam then lights symmetrically and drivers of 
oncoming vehicles are not dazzled.
On the return journey, do not forget to readjust the 
headlights.
Repositioning headlights1. Please see the chapter “REMOVING HEAD-
LIGHTS” on Page 327.
Remove headlight. Press down both release 
tabs A and remove cover.
