Kia Sonet QY 2021 Owner's Manual page 317

Driving your vehicle
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, suspen-
sion, body and wheels.
Stop driving and retighten the
chains any time you hear them
hitting the vehicle.
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, lubricates the water
pump and prevents freezing. Be
sure to replace or replenish your
coolant refer to "Normal mainte-
nance schedule" on page 8-10.
Before winter, have your coolant
tested to assure that its freezing
point is sufficient for the tempera-
tures anticipated during the winter.
Check battery and cables
Winter puts additional burdens on
the battery system. Visually inspect
the battery and cables (refer to "For
best battery service" on page 8-31).
The level of charge in your battery
can be checked by an authorised Kia
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. Refer to "Recommended
lubricants and capacities" on page
9-6 for recommendations. If you
aren't sure what weight oil you
should use, Kia recommends to con-
sult an authorised Kia dealer/service
partner.
Check spark plugs and ignition sys-
tem
Inspect your spark plugs as
described in "Scheduled mainte-
nance service" on page 8-9 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.
