CAUTION Always check chain installation for proper
mounting after driving about 0.3-0.6 mi.
(0.5-1 km) to ensure safe mounting.
Retighten or remount the chains if they
are loose.

Chain installation
When installing tire chains, follow the
manufacturer’s instructions and mount
them as tightly possible. Drive slowly (less
than 20 mph (30 km/h)) with chains
installed. If you hear the chains
contacting the body or chassis, stop and
tighten them. If they still make contact,
slow down until the noise stops. Remove
the tire chains as soon as you begin
driving on cleared roads.
When mounting snow chains, park the
vehicle on level ground away from traffic.
Turn on the vehicle Hazard Warning
Flasher and place a triangular emergency
warning device behind the vehicle (if

Winter Precautions
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 in accordance with the
"Scheduled Maintenance Services"
section in chapter 9.
Before winter, have your coolant tested to
make sure that its freezing point is
sufficient for the temperatures
anticipated during the winter.

Check battery and cables
Winter temperatures affect battery
performance. Inspect the battery and
cables, as specified in chapter 9. The
battery charging level can be inspected
by an authorized HYUNDAI dealer or in a
service station.
To prevent locks from freezing
Spray approved de-icing fluid or glycerin
into key holes. When a lock opening is
already covered with ice, spray approved
de-icing fluid over the ice to remove it.
When an internal part of a lock freezes, try
to thaw it with a heated key. Carefully use
the heated key to avoid an injury.
Use approved window washer anti-freeze
solution
Add authorized window washer
anti-freeze solution, as specified on the
window washer container. Window
washer anti-freeze solution is available
from an authorized HYUNDAI dealer, and
most vehicle accessory outlets. Do not
use coolant or other types of anti-freeze
solution, to prevent any damage to the
vehicle paint.
Do not let your parking brake freeze
Under some conditions, your parking
brake may freeze in the engaged position.
This is most likely to happen when there is
an accumulation of snow or ice around or
near the rear brakes or the brakes are wet.
When there is the risk that your parking
brake may freeze: temporarily apply the
parking brake with the gear in P (Park),
then block the rear wheels, and then
release the parking brake.Do not let ice and snow accumulate
underneath
Under some conditions, snow and ice
may build up under the fenders and
interfere with the steering. When driving
in such conditions during the severe
winter, check underneath the vehicle on a
regular basis, to make sure that the front
wheels and the steering components are
not blocked.
Carry emergency equipment
In accordance with weather conditions,
carry appropriate emergency equipment,
while driving. Some of the items you may
want to carry include tire chains, tow
straps or chains, flashlight, emergency
flares, sand, shovel, jumper cables,
window scraper, gloves, ground cloth,
coveralls, blanket, etc.
Do not place objects or materials in the
motor compartment
Putting objects or materials in the motor
compartment may cause a motor failure.
Such damage is not be covered by the
manufacturer’s warranty.

Coolant
B9001901
Check the condition and connections of
all cooling system hoses and heater
hoses. Replace any swollen or
deteriorated hoses.
The coolant level should be filled between
the MAX or F and the MIN or L marks on
the side of the coolant reservoir when the
parts in the motor compartment is cool.
If the coolant level is low, have the vehicle
inspected by an authorized HYUNDAI
dealer.
WARNING
Keep hands, clothing, and tools away
from the rotating fan blades of the
cooling fan. The cooling fan may continue
to operate even though the vehicle is
turned off and can cause serious injury.
The electric motor for the cooling fan is
controlled by vehicle coolant
temperature, refrigerant pressure and
vehicle speed. As the vehicle coolant
temperature decreases, the electric
motor will automatically shut off.

Recommended coolant
• When adding coolant, use only deionized water, distilled water, or soft
water for your vehicle and never mix
hard water in the coolant filled at the
factory.
• An incorrect coolant mixture may result in severe malfunction or motor
damage.
• Do not use alcohol or methanol coolant or mix them with the specified coolant.
• Do not use a solution that contains more than 60% antifreeze or less than
35% antifreeze, which could reduce the
effectiveness of the solution.
For mixing percentage, refer to the
following table:
Information If in doubt about the mix ratio, a 50 % water
and 50 % antifreeze mix is the easiest to mix
together because it is the same quantity for
each.

Temperature - A, B & C
The temperature grades are A (the
highest), B and C representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled
conditions on a specified indoor
laboratory test wheel.
Sustained high temperature can
cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure. Grades B and A
represent higher levels of
performance on the laboratory test
wheel than the minimum required by
law.
WARNING The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded.
Excessive speed, under-inflation,
over-inflation, or excessive loading,
either separately or in combination,
can cause heat build-up and possible
sudden tire failure. This may cause
loss of vehicle control resulting in an
accident.
