Illuminated engine start/stop but-
ton
Whenever the front door is opened, the
engine start/stop button will illuminate for
your convenience. The light will go off
after about 30 seconds when the door is
closed.
Engine start/stop button position
OFF
To turn off the engine (START/RUN posi-
tion) or vehicle power (ON position),
press the engine start/stop button with
the shift lever in P(Park). When you press
the engine start/stop button without the
shift lever in P(Park), the engine
start/stop button does not turn to the
OFF position but to the ACC position.
If you turn the engine start/stop button off
and remove the smart key from the smart
key holder, the steering wheel will lock.
If you turn the engine start/stop button off
when the smart key isn't in the smart key
holder and open the driver's door, the
steering wheel will lock.
✽NOTICE
• If difficulty is experienced turning the
engine start/stop button to the ACC
position, turn the steering wheel right
and left to release the tension while
pressing the engine start/stop button.
• When you turn off the engine, the
vehicle should be stopped.

WARNING
• When you intend to park or stop
the vehicle with the engine on, be
careful not to depress the accel-
erator pedal for a long period of
time. It may overheat the engine
or exhaust system and cause fire.
• When you make a sudden stop or
turn the steering wheel rapidly,
loose objects may drop on the
floor and it could interfere with
the operation of the foot pedals,
possibly causing an accident.
Keep all things in the vehicle
safely stored.
• If you do not focus on driving, it
may cause an accident. Be care-
ful when operating what may dis-
turb driving such as audio or
heater. It is the responsibility of
the driver to always drive safely.

Maintenance
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 trav-
eling 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 oper-
ation of your transmission occurs,
check the transmission fluid level.
• Check automatic transmission P (Park)
function.
• Check parking brake.
• Check for fluid leaks under your vehicle
(water dripping from the air condition-
ing system during or after use is nor-
mal).
At least monthly:
• Check coolant level in the engine
coolant reservoir.
• Check the operation of all exterior
lights, including the stoplights, turn sig-
nals and hazard warning flashers.
• Check the inflation pressures of all
tires including the spare.
At least twice a year
(i.e., every Spring and Fall):
• Check radiator, heater and air condi-
tioning hoses for leaks or damage.
• Check windshield washer spray and
wiper operation. Clean wiper blades
with clean cloth dampened with wash-
er fluid.
• Check headlight alignment.
• Check muffler, exhaust pipes, shields
and clamps.
• Check the lap/shoulder belts for wear
and function.
• Check for worn tires and loose wheel
lug nuts.

Maintenance
20 7
Check the condition and connections of
all cooling system hoses and heater
hoses. Replace any swollen or deterio-
rated hoses.
The coolant level should be
filled between F and L
marks on the side of the
coolant reservoir when the
engine is cool.
If the coolant level is low, add enough
distilled (deionized) water. Bring the level
to F, but do not overfill. If frequent addi-
tions are required, see an authorized
HYUNDAI dealer for a cooling system
inspection.
Recommended engine coolant
• When adding coolant, use only deion-
ized water or soft water for your vehicle
and never mix hard water in the
coolant filled at the factory. An improp-
er coolant mixture can result in serious
malfunction or engine damage.
• The engine in your vehicle has alu-
minum engine parts and must be pro-
tected by an ethylene-glycol-based
coolant to prevent corrosion and freez-
ing.
• 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 would reduce
the effectiveness of the solution.
For mixture percentage, refer to the fol-
lowing table.
OBH078004
WARNING
The electric motor (cool-
ing fan) is controlled by
engine coolant tempera-
ture, refrigerant pres-
sure and vehicle speed.
It may sometimes operate even
when the engine is not running.
Use extreme caution when working
near the blades of the cooling fan
so that you are not injured by a
rotating fan blades. As the engine
coolant temperature decreases, the
electric motor will automatically
shut off. This is a normal condition.
If your vehicle is equipped with
GDI, the electric motor (cooling fan)
may operate until you disconnect
the negative battery cable.
(Continued)
• Even if the engine is not operat-
ing, do not remove the radiator
cap or the drain plug while the
engine and radiator are hot. Hot
coolant and steam may still blow
out under pressure, causing seri-
ous injury.
