Battery Sensor Deactivation
The battery sensor is deactivated,
when the battery is disconnected
from the negative pole for mainte-
nance purpose.
In this case, the ISG system is limit-
edly operated due to the battery sen-
sor deactivation. Thus, the driver
needs to take the following proce-
dures to reactivate the battery sen-
sor after disconnecting the battery.
Prerequisites to reactivate thebattery sensor
Keep the engine in the OFF status
for 4 hours, and attempt to restart the
engine 3 to 4 times for the battery-
sensor reactivation.
Pay extreme caution not to connect
any accessories (i.e. navigation and
black box) to the vehicle with the
engine in the OFF status. If not, the
battery sensor may not be reactivat-
ed.
Information
The ISG system may not operate in
the following situations.
- There is a malfunction with the ISG
system.
- The battery is weak.
- The brake vacuum pressure is low.
If this occurs, have the ISG system
checked by an authorized HYUNDAI
dealer. Use only a genuine HYUNDAI
ISG battery for replacement. If
not, the ISG system may not nor-
mally operate.
Do not recharge the ISG battery with a general battery charger. It
may damage or explode the ISG
battery.
Do not remove the battery cap. The battery electrolyte, which is
harmful to the human body, may
leak out.

- When using tire chains:
Wrong size chains or improperlyinstalled chains can damage
your vehicle's brake lines, sus-
pension, body and wheels.
Use SAE "S" class or wire chains.
If you hear noise caused by chains contacting the body,
retighten the chain to prevent
contact with the vehicle body.
To prevent body damage, retighten the chains after driving
0.3~0.6 miles (0.5~1.0 km).
Do not use tire chains on vehi- cles equipped with aluminum
wheels. If unavoidable, use a
wire type chain.
Use wire chains less than 0.59 inch (15 mm) wide to prevent
damage to the chain’s connec-
tion.
Winter Precautions
Use high quality ethylene glycolcoolant
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 cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in chapter 7. Before winter,
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.
Change to "winter weight" oil ifnecessary
In some climates it is recommended
that a lower viscosity "winter weight"
oil be used during cold weather. See
chapter 8 for recommendations. If
you aren't sure what weight oil you
should use, consult an authorized
HYUNDAI dealer.
Check battery and cables
Winter puts additional burdens on
the battery system. Visually inspect
the battery and cables as described
in chapter 7. The level of charge in
your battery can be checked by an
authorized HYUNDAI dealer or a
service station.

What to do in an emergency
If you Have a Flat Tire While
Driving
If a tire goes flat while you are driving:
Take your foot off the acceleratorpedal and let the vehicle slow down
while driving straight ahead. Do not
apply the brakes immediately or
attempt to pull off the road as this
may cause loss of vehicle control
resulting in an accident. When the
vehicle has slowed to such a speed
that it is safe to do so, brake care-
fully and pull off the road. Drive off
the road as far as possible and
park on firm, level ground. If you
are on a divided highway, do not
park in the median area between
the two traffic lanes.
When the vehicle is stopped, press the hazard warning flasher button,
move the shift lever into P (Park),
and apply the parking brake, and
place the ignition switch in the
LOCK/OFF position.
Have all passengers get out of the vehicle. Be sure they all get out on
the side of the vehicle that is away
from traffic.
When changing a flat tire, follow the instructions provided later in
this chapter.
If the Engine Doesn't Turn
Over or Turns Over Slowly
Be sure the shift lever is in N
(Neutral) or P (Park). The engine
starts only when the shift lever is in
N (Neutral) or P (Park).
Check the battery connections to be sure they are clean and tight.
Turn on the interior light. If the light dims or goes out when you oper-
ate the starter, the battery is
drained.
Do not push or pull the vehicle to
start it. This could cause damage to
your vehicle. See instructions for
"Jump Starting" provided in this
chapter.
If the Engine Turns Over
Normally but Doesn't Start
Check the fuel level and add fuel if
necessary.
If the engine still does not start, have
your vehicle checked by an author-
ized HYUNDAI dealer.

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 is always present in battery cells,
is highly combustible,
and may explode if ignit-
ed.
Keep batteries out of
reach of children.
WARNING Batteries contain sulfu-
ric acid which 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 imme-
diate medical attention. If acid
gets on your skin, thoroughly
wash the area. If you feel pain or
a burning sensation, get med-
ical 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.

Information
An inappropriately disposedbattery can be harmful to the
environment and human
health. Dispose of the battery
according to your local law(s)
or regulations.
To prevent damage to your vehicle:
Only use a 12-volt power supply (battery or jumper system) to
jump start your vehicle.
Do not attempt to jump start your vehicle by push-starting.
Jump starting procedure
1. Position the vehicles close enough that the jumper cables will reach,
but do not allow the vehicles to
touch.
2. Avoid fans or any moving parts in the engine compartment at all
times, even when the vehicles are
turned off.
3. Turn off all electrical devices such as radios, lights, air conditioning,
etc. Put the vehicles in P (Park)
and set the parking brakes. Turn
both vehicles OFF. 4. Connect the jumper cables in the
exact sequence shown in the illus-
tration. First connect one jumper
cable to the red, positive (+)
jumper terminal of your vehicle (1).
5. Connect the other end of the jumper cable to the red, positive
(+) battery/jumper terminal of the
assisting vehicle (2).
6. Connect the second jumper cable to the black, negative (-) battery/
chassis ground of the assisting
vehicle (3).

What to do in an emergency
7. Connect the other end of the sec- ond jumper cable to the black,
negative (-) chassis ground of your
vehicle (4).
Do not allow the jumper cables to contact anything except the cor-
rect battery or jumper terminals or
the correct ground. Do not lean
over the battery when making con-
nections.
8. Start the engine of the assisting vehicle and let it run at approxi-
mately 2,000 rpm for a few min-
utes. Then start your vehicle.
9. Operate your vehicle for at least 30 minutes of driving or at least 60
minutes of engine running at idle
before shutting off the engine.
Without sufficient time to charge
the battery, another no-start will
occur. You can also visit your near-
est dealer to request the battery
be charged and tested.
If your vehicle will not start after a
few attempts, it probably requires
servicing. In this event please seek
qualified assistance. If the cause of
your battery discharging is not
apparent, have your vehicle checked
by an authorized HYUNDAI dealer. Disconnect the jumper cables in the
exact reverse order you connected
them:
1. Disconnect the jumper cable from
the black, negative (-) chassis
ground of your vehicle (4).
2. Disconnect the other end of the jumper cable from the black, neg-
ative (-) 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, posi-
tive (+) jumper terminal of your
vehicle (1). If your temperature gage indicates
overheating, you experience a loss
of power, or hear loud pinging or
knocking, the engine may be over-
heating. If this happens, you should:
1. Pull off the road and stop as soon
as it is safe to do so.
2. Place the shift lever in P (Park) and set the parking brake. If the air
conditioning is ON, turn it OFF.
3. If engine coolant is running out under the vehicle or steam is com-
ing out from the hood, stop the
engine. Do not open the hood until
the coolant has stopped running or
the steaming has stopped. If there
is no visible loss of engine coolant
and no steam, leave the engine
running and check to be sure the
engine cooling fan is operating. If
the fan is not running, turn the
engine off.
