You can be temporarily blinded by approaching
headlamps. It can take a second or two, or even
several seconds, for your eyes to re-adjust to the
dark. When you are faced with severe glare, as
from a driver who does not lower the high beams, or
a vehicle with misaimed headlamps, slow down a
little. Avoid staring directly into the approaching
headlamps.
Keep the windshield and all the glass on your
vehicle clean — inside and out. Glare at night is
made much worse by dirt on the glass. Even
the inside of the glass can build up a lm caused
by dust. Dirty glass makes lights dazzle and
ash more than clean glass would, making the
pupils of your eyes contract repeatedly.
Remember that the headlamps light up far less of a
roadway when you are in a turn or curve. Keep your
eyes moving; that way, it is easier to pick out dimly
lighted objects. Just as the headlamps should be
checked regularly for proper aim, so should your
eyes be examined regularly. Some drivers suffer
from night blindness — the inability to see in dim
light — and are not even aware of it.Driving in Rain and on Wet Roads
Rain and wet roads can mean driving trouble. On a
wet road, you cannot stop, accelerate, or turn as
well because your tire-to-road traction is not as
good as on dry roads. And, if your tires do not have
much tread left, you will get even less traction. It is
always wise to go slower and be cautious if rain
starts to fall while you are driving. The surface may
get wet suddenly when your re exes are tuned for
driving on dry pavement.

Headlamp Aiming
Headlamp aim has been preset at the factory
and should need no further adjustment.
However, if your vehicle is damaged in an
accident, the headlamp aim may be affected.
Aim adjustment to the low-beam headlamps may
be necessary if it is difficult to see the lane
markers (for horizontal aim), or if oncoming drivers
ash their high-beam headlamps at you (for
vertical aim).
If you believe your headlamps need to be
re-aimed, it is recommend that you take the
vehicle to your dealer for service.

voltage. If you try to service any of the
system components, you could be
seriously injured. Have your dealer or a
quali ed technician service them.
Your vehicle has HID headlamps. After your
vehicle’s HID headlamp bulb has been replaced,
you may notice that the beam is a slightly different
shade than it was originally. This is normal.
