Driving your vehicle
WARNING
n Tire chains
• The use of chains may adversely
affect vehicle handling.
• Do not exceed 30 km/h (20 mph)
or the chain manufacturer's rec‐
ommended speed limit, whichever
is lower.
• Drive carefully and avoid bumps,
holes, sharp turns, and other road
hazards, which may cause the ve‐
hicle 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, suspen‐
sion, body and wheels.

Use high quality ethylene glycol
coolant
Your vehicle is delivered with high quali‐
ty 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 sys‐
tem, lubricates the water pump and
prevents freezing. Be sure to replace or
replenish your coolant in accordance
with the maintenance schedule in
Cooling system on page 8-21. Be‐
fore winter, have your coolant tested
to assure that its freezing point is suf‐
ficient for the temperatures anticipa‐
ted during the winter.
Check battery and cables
Winter puts additional burdens on the
battery system. Visually inspect the
battery and cables as described in
8-40. Have the level of charge in your
battery checked by a professional
workshop. Kia recommends to visit an
authorized Kia dealer/service partner.
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, Kia recommends to consult an au‐
thorized Kia dealer/service partner.
Check spark plugs and ignition
system
Inspect your spark plugs as described in
8-21 and replace them if necessary.
Also check all ignition wiring and com‐
ponents 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. Han‐
dle the heated key with care to avoid
injury.
