AIMING THE HEADLAMPS
The alignment of your headlamps
should be checked by a qualified
service technician if:
²Oncoming motorists frequently
signal you to deactivate your
high beams, and your high
beams are not activated.
²The headlamps do not seem to
provide enough light for clear
night vision.
²The headlamp beams are
pointed substantially away from
a slightly down and to the right
position.
CLEANING AND CARING FOR
YOUR VEHICLE
Washing your vehicle
Wash your vehicle regularly with
cold or lukewarm water. Never use
strong detergents or soap. If your
vehicle is particularly dirty, use a
quality car wash detergent. Always
use a clean sponge, washing glove
or similar device and plenty of
water for best results. To avoid
spots, avoid washing when the
hood is still warm, immediately
after or during exposure to strong
sunlight.
During winter months, it is
especially important to wash the
vehicle on a regular basis. Large
quantities of dirt and road salt are
difficult to remove, and they also
cause damage to the vehicle.
