ANTENNAB870D01Y-AATGlass AntennaWhen the radio power switch is turned on
while the ignition key is in either the "ON"
or "ACC" position, your car will receive
both AM and FM broadcast signals through
the antenna in the rear window glass.
HNF2189-A
CAUTION:
o Do not clean the inner side of the rear
window glass with an abrasive type of
glass cleaner or use a scraper to
remove foreign deposits from the
inner surface of the glass as this may
cause damage to the antenna
elements.
o Avoid adding metallic coatings to the
rear window glass, such as Ni, Cd, etc.
These can disturb receiving AM and
FM broadcast signals.
!
CAUTION:
o Replace the filter every 10,000 miles
(15,000 km) or once a year.
If the car is being driven in severe
conditions such as dusty, rough roads,
more frequent climate control air filter
inspections and changes are re-
quired.
o When the air flow rate is suddenly
decreased, the system should be
checked at an authorized dealer.

I090B02JM-AATTIRE MAINTENANCE
In addition to proper inflation, correct
wheel alignment helps to decrease tire
wear. If you find a tire is worn unevenly,
have your dealer check the wheel align-
ment.
When you have new tires installed,
make sure they are balanced. This will
increase vehicle ride comfort and tire
life. Additionally, a tire shoud always be
rebalanced if it is removed from the
wheel. o Using tires and wheel other than
the recommended sizes could
cause unusual handling charac-
teristics and poor vehicle control,
resulting in a serious accident.
o Wheels that do not meet Hyundai's
specifications may fit poorly and
result in damage to the vehicle or
unusual handling and poor ve-
hicle control. WARNING: WARNING:
Tires degrade over time, even when
they are not being used. Regardless
of the remaining tread, it is recom-
mended that tires generally be re-
placed after 6 years of normal ser-
vice. Heat caused by hot climates or
frequent high loading conditions can
accelerate the aging process. Fail-
ure to follow this Warning can result
in sudden tire failure, which could
lead to a loss of control and an
accident involving serious injury or
death.
