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 damage
your vehicle's brake lines, sus-
pension, body and wheels.
• Stop driving and retighten the
chains any time you hear them
hitting the vehicle.
