Driving your vehicle
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
HYUNDAI dealer.
Check spark plugs and igni-
tion 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 HYUNDAI dealer and
most auto parts outlets. Do not use
engine coolant or other types of anti-
freeze as these may damage the
paint finish.
Don't let your parking brake
freeze
Under some conditions your parking
brake can freeze in the engaged
position. This is most likely to hap-
pen 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 shift lever in P
and block the rear wheels so the
vehicle cannot roll. Then release the
parking brake.
Don't let ice and snow accu-
mulate 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.

What to do in an emergency
4 6
IF THE ENGINE WILL NOT START
If engine doesn't turn over or
turns over slowly
1.Be sure the shift lever is in N
(Neutral) or P (Park) and the emer-
gency brake is set.
2.Check the battery connections to
be sure they are clean and tight.
3.Turn on the interior light. If the light
dims or goes out when you operate
the starter, the battery is dis-
charged.
4.Check the starter connections to
be sure they are securely tight-
ened.
5.Do not push or pull the vehicle to
start it. See instructions for "Jump
starting".
If engine turns over normally
but does not start
1.Check fuel level.
2.With the engine start/stop button in
the OFF position, check all con-
nectors at the ignition coils and
spark plugs. Reconnect any that
may be disconnected or loose.
3.If the engine still does not start, we
recommend that you call an
authorized HYUNDAI dealer or
seek other qualified assistance.
WARNING
If the engine will not start, do
not push or pull the vehicle to
start it. This could result in a
collision or cause other dam-
age.
