CAUTION
• Improper jump starting procedure
can result in battery explosion and
acid burn hazard.
• Loosely connected battery cables
could damage the electronic control
units.
• To disconnect battery terminals
wait for at least 2 minutes to allow
discharge of high voltage or it could
lead to personal injury.
• While disconnecting, always
disconnect the -VE terminal first and
while connecting, always connect the
-VE terminal last.
NOTICE
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.
i Information
Pb
An inappropriately disposed
battery can be harmful to the
environment and human health.
Dispose the battery according to
your local law(s) or regulation.
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 N (Neutral,
for Automated manual transmission
vehicle) or neutral (for manual
transmission vehicle), and set the
parking brakes. Turn both vehicles
OFF.

the exact sequence shown in the
illustration. 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).

If your temperature gauge indicates
overheating, you experience a loss of
power, or hear loud pinging or knocking,
the engine may be overheating. 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 N (Neutral,
for Automated manual transmission
vehicle) or neutral (for manual
transmission vehicle) 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 coming 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.
WARNING
While the engine is running,
keep hands, clothing and
tools away from the moving
parts such as the cooling
fan and drive belt to
prevent serious injury.4. Check for coolant leaking from the
radiator, hoses or under the vehicle. (If
the air conditioning had been in use, it
is normal for cold water to be draining
from it when you stop.)
5. If engine coolant is leaking out,
stop the engine immediately and
we recommend that you call an
authorized HYUNDAI dealer for
assistance.
WARNING
NEVER remove the radiator
cap or the drain plug while
the engine and radiator are
hot. Hot coolant and steam
may blow out under
pressure, causing serious injury.
Turn the engine off and wait until the
engine cools down. Use extreme care
when removing the radiator cap. Wrap
a thick towel around it, and turn it
counterclockwise slowly to the first
stop. Step back while the pressure
is released from the cooling system.
When you are sure all the pressure
has been released, press down on the
cap, using a thick towel, and continue
turning counterclockwise to remove it.

Changing tires
WARNING
A vehicle can slip or roll off of a jack
causing serious injury or death to you
or those nearby. Take the following
safety precautions:
• Do not get under a vehicle that is
supported by a jack.
• NEVER attempt to change a tire in
the lane of traffic. ALWAYS move the
vehicle completely off the road on
level, firm ground away from traffic
before trying to change a tire. If you
cannot find a level, firm place off
the road, call a towing service for
assistance.
• Be sure to use the jack provided with
the vehicle.
• ALWAYS place the jack on the
designated jacking positions on the
vehicle and NEVER on the bumpers
or any other part of the vehicle for
jacking support.
• Do not start or run the engine while
the vehicle is on the jack.
• Do not allow anyone to remain in the
vehicle while it is on the jack.
• Keep children away from the road
and the vehicle.Follow these steps to change your
vehicle’s tire:
1. Park on a level, firm surface.
2. Move the shift lever into N (Neutral,
for Automated manual transmission
vehicle) or neutral (for manual
transmission vehicle), apply the
parking brake, and place the ignition
switch in the LOCK/OFF position.
3. Press the hazard warning flasher
button.
4. Remove the wheel lug nut wrench,
jack, jack handle, and spare tire from
the vehicle.
5. Block both the front and rear of the
tire diagonally opposite of the tire you
are changing.

• Use a towing cable or chain less than 5
m (16 feet) long. Attach a white or red
cloth (about 30 cm (12 inches) wide)
in the middle of the cable or chain for
easy visibility.
• Drive carefully so the towing cable or
chain remains tight during towing.
• Before towing, check the Automated
manual transmission for fluid leaks
under your vehicle. If the Automated
manual transmission fluid is leaking,
flatbed equipment or a towing dolly
must be used.
NOTICE
Accelerate or decelerate the vehicle
in a slow and gradual manner while
maintaining tension on the tow rope
or chain to start or drive the vehicle,
otherwise tow hooks and the vehicle
may be damaged.
NOTICE
To avoid damage to your vehicle and
vehicle components when towing:
• Always pull straight ahead when
using the towing hooks. Do not pull
from the side or at a vertical angle.
• Do not use the towing hooks to pull
a vehicle out of mud, sand or other
conditions from which the vehicle
cannot be driven out under its own
power.
• The vehicle should be towed at a
speed of 25 km/h (15 mph) or less
within the distance of 20 km (12
miles). (for Manual transmission/
Automated manual transmission
vehicle)
• The vehicle should be towed at a
speed of 15 km/h (10 mph) or less
within the distance of 1.5 km (1
mile). (for Dual clutch transmission/
Intelligent variable transmission
vehicle)

While operating your vehicle:
• Note any changes in the sound of the
exhaust or any smell of exhaust fumes
in the vehicle.
• Check for vibrations in the steering
wheel. Notice any increased steering
effort or looseness in the steering
wheel, or change in its straight-ahead
position.
• Notice if your vehicle constantly turns
slightly or “pulls” to one side when
traveling on smooth, level road.
• When stopping, listen and check for
unusual sounds, pulling to one side,
increased brake pedal travel or “hard-
to-push” brake pedal.
• If any slipping or changes in the
operation of your transmission occurs,
check the transmission fluid level.
• Check the parking brake.
• Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
• Check the coolant level in the engine
coolant reservoir.
• Check the operation of all exterior
lights, including the stoplights, turn
signals and hazard warning flashers.
• Check the inflation pressures of all
tires including the spare for tires that
are worn, show uneven wear, or are
damaged.
• Check for loose wheel lug nuts.
At least twice a year
(i.e., every Spring and Fall):
• Check the radiator, heater and air
conditioning hoses for leaks or
damage.
• Check the windshield washer spray
and wiper operation. Clean wiper
blades with clean cloth dampened
with washer fluid.
• Check the headlight alignment.
• Check the muffler, exhaust pipes,
shields and clamps.
• Check the lap/shoulder belts for wear
and function.
At least once a year:
• Clean the body and door drain holes.
• Lubricate the door hinges and checks,
and hood hinges.
• Lubricate the door and hood locks and
latches.
• Lubricate the door rubber
weatherstrips.
• Check the air conditioning system.
• Inspect and lubricate Automated
manual transmission linkage and
controls.
• Clean the battery and terminals.
• Check the brake/clutch fluid level.
