Features of your vehicle
3. Do not drive the vehicle if leaks arefound, the warning light remains on or
the brakes do not operate properly.
Have the vehicle towed to any author-
ized HYUNDAI dealer for a brake sys-
tem inspection and necessary repairs.
Your vehicle is equipped with dual-diago-
nal braking systems. This means you still
have braking on two wheels even if one
of the dual systems should fail. With only
one of the dual systems working, more
than normal pedal travel and greaterpedal pressure are required to stop the
car. Also, the car will not stop in as short
a distance with only a portion of the
brake system working. If the brakes fail
while you are driving, shift to a lower gear
for additional engine braking and stop the
car as soon as it is safe to do so.
To check bulb operation, check whether
the parking brake and brake fluid warning
light illuminates when the ignition switchis in the ON position. D150339APAO/D OFF indicator
(if equipped)
The O/D OFF indicator will illuminate
when the ignition switch is turned ON,
but should go off after approximately 3
seconds. This indicator comes on when
the O/D system is deactivated.
Engine coolant tempera-ture warning light (if equipped)
The warning light shows the temperature of the engine coolant when the ignition
switch is ON.
The warning light illuminates if the tem-
perature of the engine coolant is above120±3°C (248±5.5°F).
Do not continue driving with an overheat-
ed engine. If your vehicle overheats, refer
to “Overheating” in the Index.
✽✽ NOTICE
If the engine coolant temperature warn-
ing light illuminates, it indicates over-
heating that may damage the engine.
WARNING
Driving the vehicle with a warning
light on is dangerous. If the brake
warning light remains on, have the
brakes checked and repaired imme-
diately by an authorized HYUNDAI
dealer.

Your vehicle may be equipped with the ISG system, which reduces fuel con-
sumption by automatically shutting down
the engine, when the vehicle is at astandstill.
(For example : red light, stop sign and
traffic jam)
The engine starts automatically as soon
as the starting conditions are met.
✽✽
NOTICE
When the engine automatically starts by
the ISG system, some warning lights
(ABS, ESP, ESP OFF or Parking brake
warning light) may turn on for a few
seconds.
This happens because of low battery
voltage. It does not mean the system is
malfunctioning.
ISG (Idle Stop and Go) Operation
The ISG system is ON whenever the igni-
tion switch is turned on.
The engine will enter the idle stop (AUTO
STOP) mode automatically when all ofthe essential conditions are met. The gear is not engaged & clutch not
pressed
The vehicle speed should be over 10km/h at least once after key starting
or idle starting.
The vehicle speed should be below 5km/h
The outside temperature is between 2°C to 35°C
The engine coolant temperature is not too low
Battery charge status is adequately high
The driver's seat belt is fastened
The driver's door and hood are closed.
It could be different up to the vehicle con- dition.

Use high quality ethylene glycol coolant
Your vehicle is delivered with high quality
ethylene glycol coolant in the cooling
system. It is the only type of coolant that
should be used because it helps prevent
corrosion in the cooling system, lubri-
cates the water pump and prevents
freezing. Be sure to replace or replenish
your coolant in accordance with themaintenance schedule in section 7.
Before winter, have your coolant tested toassure that its freezing point is sufficient
for the temperatures anticipated during
the winter. E120300AEN
Check battery and cables
Winter puts additional burdens on the
battery system. Visually inspect the bat-
tery and cables as described in section
7. The level of charge in your battery can
be checked by an authorized HYUNDAI
dealer or a service station. E120400AEN
Change to "winter weight" oil if
necessary In some climates it is recommended that
a lower viscosity "winter weight" oil be
used during cold weather. See section 9
for recommendations. If you aren't sure
what weight oil you should use, consult
an authorized HYUNDAI dealer.
E120500AUN
Check spark plugs and ignition
system (for gasoline engine)
Inspect your spark plugs as described in
section 7 and replace them if necessary.
Also check all ignition wiring and compo-
nents to be sure they are not cracked,
worn or damaged in any way.
WARNING
- Tire chains
The use of chains may adversely affect vehicle handling.
Do not exceed 30 km/h (20 mph) or the chain manufacturer’s rec-
ommended speed limit, whichev-
er is lower.
Drive carefully and avoid bumps, holes, sharp turns, and other
road hazards, which may cause
the vehicle to bounce.
Avoid sharp turns or locked- wheel braking.
CAUTION
Chains that are the wrong size or
improperly installed can damage
your vehicle's brake lines, sus-pension, body and wheels.
Stop driving and retighten the chains any time you hear themhitting the vehicle.

Driving on grades
Reduce speed and shift to a lower gear
before you start down a long or steep
downgrade. If you don’t shift down, you
might have to use your brakes so much
that they would get hot and no longer
operate efficiently.
On a long uphill grade, shift down and
reduce your speed to around 45 mph (70km/h) to reduce the possibility of engine
and transaxle overheating.
If your trailer weighs more than the max-
imum trailer weight without trailer brakes
and you have an automatic transaxle,
you should drive in D (Drive) when tow-
ing a trailer.
Operating your vehicle in D (Drive) when
towing a trailer will minimize heat build up
and extend the life of your transaxle. E140407APA
Parking on hills
Generally, you should not park your vehi-
cle with a trailer attached on a hill. People
can be seriously or fatally injured, and
both your vehicle and trailer can be dam-
aged if they begin a downhill trajectory.
However, if you ever have to park your
trailer on a hill, here’s how to do it:
1. Apply your brakes, but don’t shift into
gear.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the brakes until the chocks absorb the load.
4. Reapply the brakes. Apply your park- ing brake, and then shift to R
(Reverse) for a manual transaxle or P
(Park) for an automatic transaxle.
5. Release the brakes.
WARNING
Failure to use an approved trailer wiring harness could result in dam-
age to the vehicle electrical system
and/or personal injury.
CAUTION
When towing a trailer on steep grades (in excess of 6%) pay
close attention to the enginecoolant temperature gauge toensure the engine does not over- heat. If the needle of the coolant
temperature gauge moves acrossthe dial towards “H (or 130°C /260°F)” (HOT), pull over and stop
as soon as it is safe to do so, andallow the engine to idle until it cools down. You may proceedonce the engine has cooled suffi-
ciently.
You must decide driving speed depending on trailer weight anduphill grade to reduce the possi-bility of engine and transaxle
overheating.
WARNING - Parking on a
hill
Parking your vehicle on a hill with a
trailer attached could cause seri-
ous injury or death because the
trailer could break loose.

IF THE ENGINE OVERHEATS
F050000APA
If your temperature gauge indicates over-
heating, you experience a loss of power,
or hear loud pinging or knocking, the
engine is probably too hot. If this hap-
pens, you should:
1. Pull off the road and stop as soon as it is safe to do so.
2. Place the gear selector lever in P (auto- matic 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 car or steam is coming out from
the hood, stop the engine. Do not openthe 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 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 leaking from the radiator,
hoses or under the car. (If the air con-
ditioning had been in use, it is normal
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 call the
nearest authorized HYUNDAI dealer
for assistance. 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, call an author-
ized HYUNDAI dealer for assistance.
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.
CAUTION
Serious loss of coolant indicates there is a leak in the cooling systemand this should be checked as soonas possible by an authorized HYUNDAI dealer.

be inspected at those intervals specified
in the maintenance schedule. Make sure
that a new vapor hose or fuel filler cap iscorrectly replaced.
G050700AUN
Vacuum crankcase ventilation hoses (if equipped)
Inspect the surface of hoses for evidence
of heat and/or mechanical damage. Hard
and brittle rubber, cracking, tears, cuts,
abrasions, and excessive swelling indi-
cate deterioration. 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 contact with
any heat source, sharp edges or movingcomponent which might cause heat dam-
age or mechanical wear. Inspect all hose
connections, such as clamps and cou-
plings, 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.G050800AEN

Recommended engine coolant
Use only soft (de-mineralized) 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 specifiedcoolant.
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. G070200AEN Changing the coolant
