Use high quality ethylene glycol
coolant
Your vehicle is delivered with high quality
ethylene glycol coolant in the cooling
system. It is the only type of coolant that
should be used because it helps prevent
corrosion in the cooling system, lubri-
cates the water pump and prevents
freezing. Be sure to replace or replenish
your coolant in accordance with the
maintenance schedule in section 7.
Before winter, have your coolant tested to
assure that its freezing point is sufficient
for the temperatures anticipated during
the winter.
Check battery and cables
Winter puts additional burdens on the
battery system. Visually inspect the bat-
tery and cables as described in section
7. The level of charge in your battery can
be checked by an authorized HYUNDAI
dealer or a service station.
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 ignition
system
Inspect your spark plugs as described in
section 7 and replace them if necessary.
Also check all ignition wiring and compo-
nents to be sure they are not cracked,
worn or damaged in any way.
WARNING- Tire chains
The use of chains may adversely
affect vehicle handling.
Do not exceed 20 mph (30 km/h) or the chain manufacturer’s rec-
ommended speed limit, whichev-
er is lower.
Drive carefully and avoid bumps, holes, sharp turns, and other
road hazards, which may cause
the vehicle to bounce.
Avoid sharp turns or locked- wheel braking.
CAUTION
Chains that are the wrong size or improperly installed can damageyour vehicle's brake lines, sus-pension, body and wheels.
Stop driving and retighten the chains any time you hear themhitting the vehicle.

What to do in an emergency
2. When the vehicle is stopped, turn onyour emergency hazard flashers, set
the parking brake and put the transaxle
in P (automatic transaxle).
3. Have all passengers get out of the car. Be sure they all get out on the side of
the car that is away from traffic.
4. When changing a flat tire, follow the instruction provided later in this sec-
tion.
If vehicle stalls while driving
1. Reduce your speed gradually, keeping a straight line. Move cautiously off the
road to a safe place.
2. Turn on your emergency flashers.
3. Try to get vehicle moving in drive again. If your vehicle will not more,
contact an authorized HYUNDAI deal-
er or seek other qualified assistance. 1. If your vehicle has an automatic
transaxle, 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 discharged.
4. 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 inthe LOCK position, check all connec-
tors at ignition coils and spark plugs.
Reconnect any that may be discon-
nected or loose.
3. If the engine still does not start, call an authorized HYUNDAI dealer or seek
other qualified assistance.
IF THE VEHICLE WILL NOT START
WARNING
If the vehicle will not more, do not
push or pull the vehicle to start it.
This could result in a collision or
cause other damage. In addition,
push or pull starting may cause the
catalytic converter to be over-
loaded and create a fire hazard.

EMERGENCY STARTING
Connect cables in numerical order and
disconnect in reverse order.
Jump starting
Jump starting can be dangerous if done
incorrectly. Therefore, to avoid harm to
yourself or damage to your vehicle or
battery, follow the jump starting proce-
dures. If in doubt, we strongly recom-
mend that you have a competent techni-
cian or towing service jump start your
vehicle.
CAUTION
Use only a 12-volt jumper system.You can damage a 12-volt starting motor, ignition system, and otherelectrical parts beyond repair byuse of a 24-volt power supply (eithertwo 12-volt batteries in series or a24-volt motor generator set).
WARNING- Battery
• Keep all flames or sparks away from the battery. The battery pro-
duces hydrogen gas which may
explode if exposed to flame or
sparks.
If these instructions are not fol-
lowed exactly, serious personal
injury and damage to the vehicle
may occur! If you are not sure
how to follow this procedure,
seek qualified assistance.
Automobile batteries contain sul-
furic acid. This is poisonous and
highly corrosive. When jump
starting, wear protective glasses
and be careful not to get acid on
yourself, your clothing or on the
car.
Do not attempt to jump start the vehicle if the discharged battery
is frozen or if the electrolyte level
is low; the battery may rupture or
explode.
WARNING- Battery
Never attempt to check the elec-
trolyte level of the battery as this
may cause the battery to rupture or
explode causing serious injury.

What to do in an emergency
Jump starting procedure
1. Open the cover of battery in trunk room.
2. Make sure the booster battery is 12-volt and that its negative terminal is
grounded.
3. If the booster battery is in another vehi- cle, do not allow the vehicles to touch.
4. Turn off all unnecessary electrical loads. 5. Connect the jumper cables in the exact
sequence shown in the illustration.
First connect one end of a jumper
cable to the positive terminal of the
discharged battery (1), then connect
the other end to the positive terminal
on the booster battery (2). Proceed to
connect one end of the other jumper
cable to the negative terminal of the
booster battery (3), then the other end
to a solid, stationary, metallic point (for
example, the engine lifting bracket)
away from the battery (4). Do not con-
nect it to or near any part that moves
when the engine is cranked.
Do not allow the jumper cables to con-
tact anything except the correct battery
terminals or the correct ground. Do not
lean over the battery when making
connections. 6. Start the engine of the vehicle with the
booster battery and let it run at 2,000
rpm, then start the engine of the vehi-
cle with the discharged battery.
If the cause of your battery discharging isnot apparent, you should have your vehi-cle checked by an authorized HYUNDAI dealer.
CAUTION- Battery cables
Do not connect the jumper cablefrom the negative terminal of the booster battery to the negative ter-minal of the discharged battery.This can cause the discharged bat-tery to overheat and crack, releas- ing battery acid.
