If you're not going to drive your vehicle for 25 days or more,
remove the black, negative (

This will help keep your battery from running down.

Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you
aren't careful. See ªJump Startingº in the Index
for tips on working around a battery without
getting hurt.
Contact your dealer to learn how to prepare your vehicle

Your vehicle has a headlamp system equipped with
horizontal and vertical aim indicators. The aim has been
pre
-set at the factory and should need no further
adjustment. This is true even though your vertical and
horizontal aim indicators may not fall exactly on
the ª0º (zero) marks on their scales.
If your vehicle is damaged in an accident, the headlamp
aim may be affected. Aim adjustment may be necessary
if it is difficult to see lane markers (for horizontal aim), or
if oncoming drivers flash their high beams at you
(for vertical aim). If you believe your headlamps need to
be re
-aimed, we recommend that you take it to your dealer
for service; however, it is possible for you to re
-aim your
headlamps as described in the following procedure.
NOTICE:
To make sure your headlamps are aimed
properly, read all the instructions before
beginning. Failure to follow these instructions
could cause damage to headlamp parts.
