What to Use
Refer to the Maintenance Schedule to determine
what kind of lubricant to use. See Recommended
Fluids and Lubricants on page 590.
Headlamp Aiming
The vehicle has a visual optical headlamp aiming
system. The aim of the headlamps have been
preset at the factory and should need no further
adjustment.
However, if the vehicle is damaged in an accident,
the aim of the headlamps may be affected and
adjustment may be necessary.
If oncoming vehicles flash their high beams at
you, this may mean the vertical aim of your
headlamps needs to be adjusted.
It is recommended that the vehicle is taken to your
dealer/retailer for service if the headlamps need
to be adjusted. It is possible however, to re-aim the
headlamps as described in the following
procedure.
The vehicle should be properly prepared as
follows:
•
The vehicle should be placed so the headlamps
are 25 ft. (7.6 m) from a light colored wall.
•
The vehicle must have all four tires on a level
surface which is level all the way to the wall.
•
The vehicle should be placed so it is
perpendicular to the wall.
•
The vehicle should not have any snow, ice, or
mud on it.
•
The vehicle should be fully assembled and all
other work stopped while headlamp aiming is
being performed.
•
The vehicle should be normally loaded with a
full tank of fuel and one person or 160 lbs
(75 kg) sitting on the driver’s seat.
•
Tires should be properly inflated.
•
The spare tire is in its proper location in the
vehicle.
Headlamp aiming is done with the vehicle’s
low-beam headlamps. The high-beam headlamps
will be correctly aimed if the low-beam headlamps
are aimed properly.
