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.

Jump Starting (12 V
battery)
Jump starting can be dangerous if done
incorrectly. Follow the jump starting
procedure in this section to avoid serious
injury or damage to your vehicle. If in
doubt about how to properly jump start
your vehicle, have a service technician or
towing service do it for you.
WARNING To prevent SERIOUS INJURY or DEATH to
you or bystanders, always follow these
precautions when working near or
handling the battery:
Always read and follow instructions
carefully when handling a battery.
Wear eye protection designed to protect
the eyes from acid splashes.
Keep all flames, sparks, or smoking
materials away from the battery.Hydrogen gas is always present in battery
cells. It is highly combustible, and may
explode if ignited.
Keep batteries out of reach of children.
Batteries contain sulfuric acid that is
highly corrosive. Do not allow acid to
contact your eyes, skin, or clothing. If acid
gets into your eyes, flush your eyes with
clean water for at least 15 minutes and get
immediate medical attention. If acid gets
on your skin, thoroughly wash the area. If
you feel pain or a burning sensation, get
medical attention immediately.
• When lifting a plastic-cased battery,
excessive pressure on the case may
cause battery acid to leak. Lift with a
battery carrier or with your hands on
opposite corners.
• Do not attempt to jump start your vehicle if your battery is frozen.
• NEVER attempt to recharge the battery when the vehicle’s battery cables are
connected to the battery.

Emergency Situations

11.Start the assisting vehicle and let it run for a few minutes. Then start your
vehicle.
12.Keep your vehicle operating for at least 30 minutes at idle or driving to assure
your battery receives enough charge to
be able to start on its own after the
vehicle is shut off. A completely
discharged battery may require as long
as 60 minutes runtime to fully recharge
it. If the vehicle is run for less, battery
may not restart.
If your vehicle does not start after a few
attempts, it probably requires service.
Have your vehicle inspected by an
authorized HYUNDAI dealer.
Disconnect the jumper cables in the exact
reverse order you connected them:
1. Disconnect the jumper cable from the chassis ground of your vehicle (4).
2. Disconnect the other end of the jumper cable from battery/chassis ground of
the assisting vehicle (3).
3. Disconnect the second jumper cable from the red, positive (+)
battery/jumper terminal of the
assisting vehicle (2).
4. Disconnect the other end of the jumper cable from the red, positive (+) jumper
terminal of your vehicle (1).Information
An inappropriately disposed battery can be
harmful to the environment and human health.
Dispose of the battery according to your local
law(s) or regulations.

Low Tire Pressure Warning
Light
Low Tire Pressure Position
and Tire Pressure Telltale
B8002102
When the tire pressure monitoring
system warning indicators are illuminated
and a warning message displayed on the
cluster display, one or more of your tires is
significantly under-inflated. The Low Tire
Pressure Position Telltale will indicate
which tire is significantly underinflated by
illuminating the corresponding parking
light.
If either telltale illuminates, immediately
reduce your speed, avoid hard cornering
and anticipate increased stopping
distances. You should stop and check
your tires as soon as possible. Inflate the
tires to the proper pressure as indicated
on the vehicle’s placard or tire inflation
pressure label located on the driver’s side
center pillar outer panel.
If you cannot reach a service station or if
the tire cannot hold the newly added air,
replace the low pressure tire with the
spare tire.The Low Tire Pressure Telltale will remain
on and the TPMS Malfunction Indicator
may blink for one minute and then remain
illuminated (when the vehicle is driven
about 10 minutes at speed above 15.5
mph (25 km/h)) until you have the low
pressure tire repaired and replaced on the
vehicle.
CAUTION In winter or cold weather, the Low Tire
Pressure Telltale may be illuminated if the
tire pressure was adjusted to the
recommended tire inflation pressure in
warm weather. It does not mean your
TPMS is malfunctioning because the
decreased temperature leads to a
proportional lowering of tire pressure.
When you drive your vehicle from a warm
area to a cold area or from a cold area to a
warm area, or the outside temperature is
greatly higher or lower, you should check
the tire inflation pressure and adjust the
tires to the recommended tire inflation
pressure.

WARNING Low pressure damage
Significantly low tire pressure makes the
vehicle unstable and can contribute to
loss of vehicle control and increased
braking distances.
Continued driving on low pressure tires
can cause the tires to overheat and fail.

If You Have a Flat Tire
if equipped
(with Tire Mobility Kit)
B8002501
For safe operation, carefully read and
follow the instructions in this manual
before use.
1. Compressor
2. Sealant bottle
The tire mobility kit is a temporary fix to
the tire, have the tire inspected by an
authorized HYUNDAI dealer or the sealant
provided with the Tire Mobility Kit must
be used for only one flat tire.
CAUTION When two or more tires are flat, do not
use the tire mobility kit because the
sealant provided with the Tire Mobility Kit
must be used for only one flat tire.

WARNING Do not use the Tire Mobility Kit to repair
punctures in the tire walls. This can result
in an accident due to tire failure.

WARNING Have your tire repaired as soon as
possible. The tire may lose air pressure at
any time after inflating with the Tire
Mobility Kit.

Introduction
With the Tire Mobility Kit you can stay
mobile even after experiencing a tire
puncture.
The compressor and sealing compound
system effectively and comfortably seals
most punctures in a passenger car tire
caused by nails or similar objects and
reinflates the tire.
After you ensure that the tire is properly
sealed you can drive cautiously on the tire
(distance up to 120 mi. (200 km)) at a max.
speed of 50 mph (80 km/h) in order to
reach a service station or tire dealer for
the tire replacement.
It is possible that some tires, especially
with larger punctures or damage to the
sidewall, cannot be sealed completely.
Air pressure loss in the tire may adversely
affect tire performance.
For this reason, you should avoid abrupt
steering or other driving maneuvers,
especially if the vehicle is heavily loaded
or if a trailer is in use.
The Tire Mobility Kit is not designed or
intended as a permanent tire repair
method and is to be used for one tire only.
This instruction shows you step by step
how to temporarily seal the puncture
simply and reliably.
Read the section “Notes on the safe use
of the Tire Mobility Kit”.
