C160J01A-AATDon't Let Ice and Snow Accumulate
UnderneathUnder some conditions, snow and ice can
build up under the fenders and interfere
with the steering. When driving in severe
winter conditions where this may happen,
you should periodically check underneath
the car to be sure the movement of the front
wheels and the steering components is
not obstructed.C160I01A-AATDon't Let Your Parking Brake FreezeUnder some conditions your parking brake
can freeze in the engaged position. This
is most likely to happen when there is an
accumulation of snow or ice around or
near the rear brakes or if the brakes are
wet. If there is a risk the parking brake may
freeze, apply it only temporarily while you
put the gear selector lever in "P" (automatic)
or in first or reverse gear (manual transaxle)
and block the rear wheels so the car cannot
roll. Then release the parking brake.
C160H02A-AATUse Approved Window Washer Anti-
Freeze in SystemTo keep the water in the window washer
system from freezing, add an approved
window washer anti-freeze solution in
accordance with instructions on the
container. Window washer anti-freeze is
available from Hyundai dealers and most
auto parts outlets. Do not use engine coolant
or other types of anti-freeze as these may
damage the paint finish.C160G01A-AATTo Keep Locks from FreezingTo keep the locks from freezing, squirt an
approved de-icer fluid or glycerine into the
key opening. If a lock is covered with ice,
squirt it with an approved de-icing fluid to
remove the ice. If the lock is frozen internally,
you may be able to thaw it out by using a
heated key. Handle the heated key with
care to avoid injury.
C160F01A-AATCheck Spark Plugs and Ignition
SystemInspect your spark plugs as described in
Section 6 and replace them if necessary.
Also check all ignition wiring and
components to be sure they are not cracked,
worn or damaged in any way.C160E01A-AATChange to "Winter Weight" Oil if
NecessaryIn some climates it is recommended that a
lower viscosity "winter weight" oil be used
during cold weather. See Section 9 for
recommendations. If you aren't sure what
weight oil you should use, consult your
Hyundai dealer.
