Change to "winter weight" oil if
necessary
In some climates it is recommended
that a lower viscosity "winter weight"
oil be used during cold weather. See
section 8 for recommendations. If
you aren't sure what weight oil you
should use, consult an authorized
retailer of Genesis Branded prod-
ucts.
Check spark plugs and ignition
system
Inspect your spark plugs as
described in section 7 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.
To keep locks from freezing
To 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 heat-
ed key with care to avoid injury.
Use approved window washer
anti-freeze in system
To keep the water in the window
washer system from freezing, add an
approved window washer anti-freeze
solution in accordance with instruc-
tions on the container. Window wash-
er anti-freeze is available from an
authorized retailer of Genesis
Branded products and most auto
parts outlets. Do not use engine
coolant or other types of anti-freeze
as these may damage the paint fin-
ish.
Don't let your parking brake
freeze
Under 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 of the parking brake
may freezing, apply it only temporar-
ily while you put the shift lever in P
(automatic transaxle) or in first or
reverse gear (manual transaxle) and
block the rear wheels so the vehicle
cannot roll. Then release the parking
brake.
Don't let ice and snow accumu-
late underneath
Under 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 com-
ponents is not obstructed.

Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in
the maintenance schedule. If the car
is being driven in severe conditions,
more frequent oil and filter changes
are required.
Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil
saturation and replace if necessary.
Drive belts should be checked peri-
odically for proper tension and
adjusted as necessary.
Fuel filter
A clogged filter can limit the speed at
which the vehicle may be driven,
damage the emission system and
cause multiple issues such as hard
starting. If an excessive amount of
foreign matter accumulates in the
fuel tank, the filter may require
replacement more frequently. After
installing a new filter, run the engine
for several minutes, and check for
leaks at the connections. Fuel filters
should be installed by an authorized
retailer of Genesis Branded prod-
ucts.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. Have an authorized retailer of
Genesis Branded products replace
any damaged or leaking parts imme-
diately.
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap
should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure a new vapor
hose or fuel filler cap is correctly
replaced.
Air cleaner filter
A Genesis/Hyundai Part air cleaner
filter is recommended when the filter
is replaced.
Spark plugs
Make sure to install new spark plugs
of the correct part number and heat
range.
