Convenient features of your vehicle
For emergencies, be fully
aware of the location of the
emergency liftgate safety
release lever in this vehicle
and how to open the liftgate if
you are accidentally locked in
the luggage compartment.
No one should be allowed to
occupy the luggage compart-
ment of the vehicle at any time.
The luggage compartment is a
very dangerous location in the
event of a crash.
Use the release lever for emer-
gencies only. Use extreme cau-
tion, especially while the vehi-
cle is in motion.
WARNING Fuel Filler Door
Opening the fuel filler door
1. Turn the engine off.
2. Ensure the driver's door isunlocked.
3. Push the fuel filler door near the 3 o'clock position. 4. Pull the fuel filler door (1) out to
fully open.
5. To remove the fuel tank cap (2), turn it counterclockwise. You may
hear a hissing noise as the pres-
sure inside the tank equalizes.
6. Place the cap on the fuel filler door.
Information
If the fuel filler door does not open
because ice has formed around it, tap
lightly or push on the door to break
the ice and release the door. Do not
pry on the door. If necessary, spray
around the door with an approved de-
icer fluid (do not use radiator anti-
freeze) or move the vehicle to a warm
place and allow the ice to melt.

Fuel gauge
This gauge indicates the approxi-
mate amount of fuel remaining in the
fuel tank.
Information
• The fuel tank capacity is given inchapter 8.
• The fuel gauge is supplemented by a low fuel warning light, which will
illuminate when the fuel tank is
nearly empty.
• On inclines or curves, the fuel gauge pointer may fluctuate or the low fuel
warning light may come on earlier
than usual due to the movement of
fuel in the tank. Avoid driving with an extremely
low fuel level. Running out of fuel
could cause the engine to misfire
damaging the catalytic converter.
NOTICE
i
Never remove the radiator cap or
reservoir cap when the engine is
hot. The engine coolant is under
pressure and could severely
burn. Wait until the engine is cool
before adding coolant to the
reservoir.
WARNING
OPD047462N
Running out of fuel can expose
vehicle occupants to danger.
You must stop and obtain addi-
tional fuel as soon as possible
after the warning light comes
on or when the gauge indicator
comes close to the "E (Empty)"
level.

What to do in an emergency
6
4. Check for coolant leaking from theradiator, hoses or under the vehi-
cle. (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
call the nearest authorized
HYUNDAI dealer for assistance. 6. If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to nor-
mal. Then, if coolant has been
lost, carefully add coolant to the
reservoir to bring the fluid level in
the reservoir up to the halfway
mark.
7. Proceed with caution, keeping alert for further signs of overheat-
ing. If overheating happens again,
call an authorized HYUNDAI deal-
er for assistance.
While the engine is
running, keep hands,
clothing and tools
away from the mov-
ing parts such as the
cooling fan and drive
belt to prevent seri-
ous injury.
WARNING
Serious loss of coolant indi-
cates a leak in the cooling sys-
tem and should be checked as
soon as possible by an author-
ized HYUNDAI dealer.
CAUTION
Your vehicle is
equipped with a pres-
surized coolant
reserve tank. NEVER
remove the engine
coolant reservoir tank/radiator
cap or the drain plug while the
engine and radiator are HOT.
Hot coolant and steam may
blow out under pressure, caus-
ing serious injury.
Turn the engine off and wait
until the engine cools down.
Use extreme care when remov-
ing the engine coolant reservoir
tank/radiator cap. Wrap a towel
or thick rag around it, and turn it
counterclockwise slowly to
release some of the pressure
from the system. Step back
while the pressure is released.
When you are sure all the pres-
sure has been released, contin-
ue turning the cap counter-
clockwise to remove it.

Maintenance
Air Cleaner Filter
A genuine HYUNDAI air cleaner filter
is recommended when the filter is
replaced.
Spark Plugs
Make sure to install new spark plugs
of the correct heat range.
Cooling System
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Engine Coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Automatic Transmission Fluid
(if equipped)
Automatic transmission fluid should
not be checked under normal usage
conditions. But in severe conditions,
the fluid should be changed at an
authorized HYUNDAI dealer in
accordance to the scheduled mainte-
nance at the beginning of this chap-
ter.
Automatic transmission fluid
color is red when new.
As the vehicle is driven, the auto-
matic transmission fluid will begin
to look darker. This is a normal
condition and you should not
judge the need to replace the fluid
based upon the changed color.
Dual Clutch Transmission
Fluid (if equipped)
Inspect the dual clutch transmission
fluid according to the maintenance
schedule.
Manual Transmission Fluid
(if equipped)
Inspect the manual transmission
fluid according to the maintenance
schedule.
NOTICE
The use of a non-specified fluid
could result in transmission
malfunction and failure. Use
only the specified automatic
transmission fluid (refer to
"Recommended Lubricants and
Capacities" in chapter 8).
CAUTION

MaintenanceThe electric motor for the cooling fan
is controlled by engine coolant tem-
perature, refrigerant pressure and
vehicle speed. 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 for the cooling fan may begin
to operate at any time and continue
to operate until you disconnect the
negative battery cable.The electric motor for
the cooling fan may
continue to operate
or start up when the
engine is not running
and can cause serious injury.
Keep hands, clothing and tools
away from the rotating fan
blades of the cooling fan.
WARNING
Never remove the
engine coolant reser-
voir tank/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 remov-
ing the engine coolant reservoir
tank/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 counterclock-
wise to remove it.

Changing Engine Coolant
Have coolant changed by an author-
ized HYUNDAI dealer according to
the Maintenance Schedule at the
beginning of this chapter.To prevent damage to engine
parts, put a thick towel around the
radiator cap before refilling the
coolant to prevent the coolant
from overflowing into engine
parts, such as the alternator.
NOTICE

Maintenance
Do not use engine coolant or
antifreeze in the washer fluid
reservoir.
Engine coolant can severely
obscure visibility when sprayed
on the windshield and may
cause loss of vehicle control
resulting in an accident.
Engine coolant may also cause
damage to paint and body trim.
