Features of your vehicle
Engine coolant temperature gauge
(if equipped)
This gauge shows the temperature of the
engine coolant when the ignition switch
is ON.
Do not continue driving with an overheat-
ed engine. If your vehicle overheats, refer
to “If the engine overheats” in chapter 6.
Fuel gauge
The fuel gauge indicates the approximate
amount of fuel remaining in the fuel tank.
The fuel tank capacity is given in chapter
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 warn-
ing light may come on earlier than usual
due to the movement of fuel in the tank.
OBA043107
CAUTION
If the gauge pointer moves beyond
the normal range area toward the
“H” it indicates overheating that
may damage the engine.
WARNING
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 THE ENGINE OVERHEATS
If your temperature gauge indicates over-
heating, you will experience a loss of
power, or hear loud pinging or knocking
sound, the engine will probably be too
hot. If this happens, you should:
1. Pull the vehicle off the road and stop
as soon as it is safe to do so.
2. Place the shift lever in P (automatic
transaxle) or Neutral (manual
transaxle) 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 operat-
ing. If the fan is not running, turn the
engine off.
4. Check to see if the water pump drive
belt is missing. If it is not missing,
check to see that it is tight. If the drive
belt seems to be satisfactory, check
for coolant leakage from the radiator,
hoses or under the vehicle. (If the air
conditioning had been in use, it is nor-
mal for cold water to be draining from it
when you stop).5. If the water pump drive belt is broken
or engine coolant is leaking out, stop
the engine immediately and we recom-
mend that you call an authorized
HYUNDAI dealer.6. If you cannot find the cause of the
overheating, wait until the engine tem-
perature has returned to normal. 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 overheating. If over-
heating happens again, we recom-
mend that you call an authorized
HYUNDAI dealer.
CAUTION
Serious loss of coolant indicates
there is a leak in the cooling system
and we recommend that the system
be checked by an authorized
HYUNDAI dealer.
WARNING
While the engine is running, keep
hair, hands and clothing away from
moving parts such as the fan and
drive belts to prevent injury.
WARNING
Do not remove the radiator cap
when the engine is hot. This can
allow coolant to be blown out of the
opening and cause serious burns.

Maintenance
24 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 (MAX) and L (MIN) marks on
the side of the coolant reservoir when the
engine is cool.
If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring the
level to F (MAX), but do not overfill.
If frequent additions are required, we rec-
ommend that the system be inspected by
an authorized HYUNDAI dealer.
Recommended engine coolant
• Use only soft (distilled) water in the
coolant mixture.
• 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.(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.
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.OBA073004
