Use your interior rearview mirror or
direct observation to determine the
actual distance of following vehicles
when changing lanes.Blind spot mirror
The Blind Spot Mirror (BSM) is a
supplemental mirror that reduces the
driver’s blind spot by showing the
rear side area of the vehicle. The
blind spot mirror is equipped on the
left-hand side view mirror.Do not clean the mirror with harsh
abrasives, fuel or other petroleum
based cleaning products.
NOTICE
Do not adjust or fold the side
view mirrors while driving. This
may cause loss of vehicle con-
trol resulting in an accident.
WARNING
Do not scrape ice off the mir-
ror face; this may damage the
surface of the glass.
If the mirror is jammed with
ice, do not adjust the mirror by
force. Use an approved spray
de-icer (not radiator antifreeze)
spray, or a sponge or soft cloth
with very warm water, or move
the vehicle to a warm place
and allow the ice to melt.
CAUTION

OLF044478N
Always check the road condi-
tion while driving for unex-
pected situations even though
the vehicle is equipped with a
blind spot mirror.
The blind spot mirror is a
device made for convenience.
Do not solely rely on the mir-
ror but always pay attention to
traffic around you.

3. Pull the fuel filler door (1) out to fully open.
4. To remove the fuel tank cap (2), turn it counterclockwise. You may
hear a hissing noise as the pres-
sure inside the tank equalizes.
5. 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.
Closing the fuel filler door
1. To install the fuel tank cap, turn itclockwise until it "clicks" one time.
2. Close the fuel filler door until it is latched securely.i

Do not operate the engine within
the tachometer's RED ZONE. This
may cause severe engine damage.
Engine Coolant TemperatureGauge
This gauge indicates the tempera-
ture of the engine coolant when the
ignition switch or Engine Start/Stop
button is ON. If the gauge pointer moves
beyond the normal range area
toward the "H" position, it indi-
cates overheating that may dam-
age the engine.
Do not continue driving with an
overheated engine. If your vehicle
overheats, refer to "If the Engine
Overheats" in chapter 6.

What to do in an emergency
6
If your temperature gauge 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 soonas 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. 4. Check for coolant leaking from the
radiator, 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.

clothing and tools
away from the mov-
ing parts such as the
cooling fan and drive
belt to prevent seri-
ous injury.
WARNING

What to do in an emergency6. If you cannot find the cause of theoverheating, 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.
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
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 remov-
ing 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 counterclock-
wise to remove it.
