Adjusting the rearview mirrors:
Move the lever (1) to the L (Left) or R
(Right) to select the rearview mirror
you would like to adjust.
Use the mirror adjustment control to
position the selected mirror up,
down, left or right.
After adjustment, move the lever (1)
to the middle to prevent inadvertent
adjustment.
•The outside rearview mirrors
are convex. Objects seen in
the mirror are closer than they
appear.
•Use your interior rearview
mirror or turn your head and
look to determine the actual
distance of following vehicles
when changing lanes.
WARNING
Do not adjust or fold the outside
rearview mirrors whilst driving.
This may cause loss of vehicle
control 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.

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 it
clockwise until it “clicks” one time.
2. Close the fuel filler door until it is
latched securely.i
Petrol is highly flammable and
explosive. Failure to follow
these guidelines may result in
SERIOUS INJURY or DEATH:
•Read and follow all warnings
posted at the gas station.
•Before refuelling, note the
location of the Emergency
Petrol Shut-Off, if available, at
the gas station.
•Before touching the fuel noz-
zle, you should eliminate the
potential build-up of static
electricity by touching a metal
part of the vehicle, a safe dis-
tance away from the fuel filler
neck, nozzle, or other gas
source, with your bare hand.
(Continued)
WARNING
(Continued)
•Do not use mobile phones
whilst refuelling. Electric cur-
rent and/or electronic interfer-
ence from mobile phones can
potentially ignite fuel vapours
and cause a fire.
•Do not get back into a vehicle
once you have begun refu-
elling. You can generate a
build-up of static electricity by
touching, rubbing or sliding
against any item or fabric capa-
ble of producing static electric-
ity. Static electricity discharge
can ignite fuel vapours causing
a fire. If you must re-enter the
vehicle, you should once again
eliminate potentially danger-
ous static electricity discharge
by touching a metal part of the
vehicle, away from the fuel filler
neck, nozzle or other petrol
source, with your bare hand.

Engine Coolant Temperature
gauge
This gauge indicates the tempera-
ture of the engine coolant when the
ignition switch or Engine Start/Stop
button is in the ON position.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.
Fuel Gauge
This gauge indicates the approxi-
mate amount of fuel remaining in the
fuel tank.
NOTICE
Never remove the radiator cap
when the engine is hot. The
engine coolant is under pressure
and could cause severe burns.
Wait until the engine is cool
before adding coolant to the
reservoir.

What to do in an emergency
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 soon
as it is safe to do so.
2. Place the shift lever in P (Park, for
automatic transaxle vehicle) or
neutral (for manual transaxle vehi-
cle) 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 bonnet, stop the
engine. Do not open the bonnet
until the coolant has stopped run-
ning 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
we recommend that you call an
authorised HYUNDAI dealer for
assistance.
IF THE ENGINE OVERHEATS
Whilst 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
NEVER remove the
radiator cap or the
drain plug whilst 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
anticlockwise slowly to the first
stop. Step back whilst the pres-
sure is released from the cool-
ing system. When you are sure
all the pressure has been
released, press down on the
cap, using a thick towel, and
continue turning anticlockwise
to remove it.

Maintenance
At least twice a year:
• Check radiator, heater and air condi-
tioning hoses for leaks or damage.
• Check windscreen washer spray
and wiper operation. Clean wiper
blades with clean cloth dampened
with washer fluid.
• Check headlamp alignment.
• Check muffler, exhaust pipes,
shields and clamps.
• Check the seat belts for wear and
function.
At least once a year:
• Clean body and door drain holes.
• Lubricate door hinges and bonnet
hinges.
• Lubricate door and bonnet locks
and latches.
• Lubricate door rubber weather
strips.
• Check the air conditioning system.
• Inspect and lubricate automatic
transaxle linkage and controls.
• Clean the battery and terminals.
• Check the brake fluid level.

Maintenance
Vacuum crankcase ventilation
hoses (if equipped)
Inspect the surface of hoses for evi-
dence of heat and/or mechanical
damage. Hard and brittle rubber,
cracking, tears, cuts, abrasions, and
excessive swelling indicate deterio-
ration. Particular attention should be
paid to examine those hose surfaces
nearest to high heat sources, such
as the exhaust manifold.
Inspect the hose routing to assure
that the hoses do not come in con-
tact with any heat source, sharp
edges or moving component which
might cause heat damage or mechan-
ical wear. Inspect all hose connec-
tions, such as clamps and couplings,
to make sure they are secure, and that
no leaks are present. Hoses should be
replaced immediately if there is any
evidence of deterioration or damage.
Air cleaner filter
We recommend that the air cleaner
filter be replaced by an authorised
HYUNDAI dealer.
Spark plugs
Make sure to install new spark plugs
of the correct heat range.
Valve clearance (Theta Engine)
Inspect excessive valve noise and/or
engine vibration and adjust if neces-
sary. We recommend that the system
be serviced by an authorised
HYUNDAI dealer.
Cooling system
Check the cooling system parts,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule. Do not disconnect and inspect
spark plugs when the engine is
hot. You may burn yourself.

Maintenance
ENGINE OIL
Checking the engine oil level
1. Ensure the vehicle is on level
ground.
2. Start the engine and allow it to
reach normal operating tempera-
ture.3. Turn the engine off and wait for
about 5 minutes for the oil to
return to the oil pan.
4. Pull the dipstick out, wipe it clean,
and re-insert it fully.5. Pull the dipstick out again and
check the level. The level should
be between F and L.
Radiator hose
Be very careful not to touch the
radiator hose when checking or
adding the engine oil as it may
be hot enough to burn you.
WARNING •Do not overfill the engine oil.
It may damage the engine.
•Do not spill engine oil, when
adding or changing engine
oil. If you drop the engine oil
on the engine room, wipe it off
immediately.
•When you wipe the oil level
gauge, you should wipe it with
a clean cloth. When mixed
with debris, it can cause
engine damage.
