Features of your vehicle
Tachometer
The tachometer indicates the approxi-
mate number of engine revolutions per
minute (rpm). Use the tachometer to select the correct
shift points and to prevent lugging and/or
over-revving the engine. When the door is open, or if the engine is
not started within 1 minute, the tachome-
ter pointer may move slightly in ON posi-
tion with the engine OFF. This movement
is normal and will not affect the accuracy
of the tachometer once the engine is run-ning.
Engine temperature gauge
This gauge shows the temperature of the
engine coolant when the ignition switchis ON.
Do not continue driving with an overheat-
ed engine. If your vehicle overheats, refer
to “If the engine overheats” in section 6.
CAUTION
If the gauge pointer moves beyondthe normal range area toward the“H” position, it indicates overheat-ing that may damage the engine.
CAUTION
Do not operate the engine within the tachometer's RED ZONE. This
may cause severe engine damage.

Engine coolant tempera-ture warning light (if equipped)
The warning light illuminates if the tem-
perature of the engine coolant is above125±2.5°C (257±4.5°F).
Do not continue driving with an overheat-
ed engine. If your vehicle overheats, refer
to “Overheating” in section 6.
✽✽ NOTICE
If the engine coolant temperature warn-
ing light illuminates, it indicates over-
heating that may damage the engine.
ESP (Electronic Stability Program) indicator (if equipped)
The ESP indicator will illuminate when
the ignition switch is turned ON, but
should go off after approximately 3 sec-
onds. When the ESP is on, it monitors the
driving conditions. Under normal driving
conditions, the ESP indicator will remain
off. When a slippery or low traction con-dition is encountered, the ESP will oper-
ate, and the ESP indicator will blink to
indicate the ESP is operating. But, if the ESP system malfunctions the
indicator illuminates and stays on. Take
your vehicle to an authorised HYUNDAI
dealer and have the system checked.
ESP OFF indicator
(if equipped)
The ESP OFF indicator will illuminate
when the ignition switch is turned ON,
but should go off after approximately 3
seconds. To switch to ESP OFF mode,
press the ESP OFF button. The ESPOFF indicator will illuminate indicating
the ESP is deactivated.
CAUTION
Prolonged driving with the Malfunction Indicator Light illumi-
nated may cause damage to theemission control systems whichcould effect drivability and/or fuel economy.
CAUTION
If the Malfunction Indicator Lightilluminates, potential catalytic con-verter damage is possible which could result in loss of engine
power. Have the Engine ControlSystem inspected as soon as pos-sible by an authorised HYUNDAIdealer.

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.
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 authorised HYUNDAI
dealer or a service station. 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 8
for recommendations. If you aren't sure
what weight oil you should use, consult
an authorised HYUNDAI dealer.
Check spark plugs and ignition system
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
- Tyre 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.

Parking on hills
Generally, if you have a trailer attached to
your vehicle, you should not park your
vehicle on a hill. People can be seriously
or fatally injured, and both your vehicle
and the trailer can be damaged if unex-
pectedly roll down hill. However, if you ever have to park your
trailer on a hill, here's how to do it:
1. Pull the vehicle into the parking space.
Turn the steering wheel in the direction
of the kerb (left if headed down hill,
right if headed up hill).
2. If the vehicle has a manual transaxle, place the car in neutral. If the vehicle
has an automatic transaxle, place the
car in P (Park).
3. Set the parking brake and shut off the vehicle.
4. Place chocks under the trailer wheels on the down hill side of the wheels.
5. Start the vehicle, hold the brakes, shift to neutral, release the parking brake
and slowly release the brakes until the
trailer chocks absorb the load.
6. Reapply the brakes, reapply the park- ing brake and shift the vehicle to R
(Reverse) for manual transaxle or P
(Park) for automatic transaxle.
7. Shut off the vehicle and release the vehicle brakes but leave the parking
brake set.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 tem-perature gauge moves across thedial towards “H” (HOT), pull overand stop as soon as it is safe to
do so, and allow the engine to idleuntil it cools down. You may pro-ceed once the engine has cooledsufficiently.
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, should the trail-
er break loose.

What to do in an emergency
IF THE ENGINE OVERHEATS
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 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 car or steam is coming out from
the bonnet, stop the engine. Do notopen the bonnet 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 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 authorised 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 autho-
rised HYUNDAI dealer for assistance.
WARNING
Whilst 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 authorised HYUNDAI dealer.

ENGINE COOLANT
The high-pressure cooling system has a
reservoir filled with year-round antifreeze
coolant. The reservoir is filled at the fac-
tory.
Check the antifreeze protection and
coolant level at least once a year, at thebeginning of the winter season, and
before travelling to a colder climate. Checking the coolant level
WARNING
Removing radiatorcap
Never attempt to remove the radi- ator cap whilst the engine is
operating or hot. Doing so mightlead to cooling system and
engine damage and could result
in serious personal injury fromescaping hot coolant or steam.
Turn the engine off and wait until it cools down. Use extreme care
when removing the radiator cap.
Wrap a thick towel around it, and
turn it counterclockwise slowly to
the first stop. Step back whilst
the pressure is released from the
cooling system. When you aresure all the pressure has been
released, press down on the cap,
using a thick towel, and continue
turning counterclockwise to
remove it.
(Continued)
WARNING The electric motor (cool-
ing fan) is controlled byengine coolant tempera-
ture, refrigerant pres-
sure and vehicle speed.
It may sometimes operate evenwhen 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.
(Continued)
Even if the engine is not operat- ing, do not remove the radiator cap or the drain plug whilst the
engine and radiator are hot. Hot
coolant and steam may still blow
out under pressure, causing seri-
ous injury.

Maintenance
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 and L marks on the side of the
coolant reservoir when the engine iscool.
If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring the
level to F, but do not overfill. If frequent
additions are required, see an authorised
HYUNDAI dealer for a cooling systeminspection.
Recommended engine coolant
When adding coolant, use only deion-ized water or soft water for your vehicle
and never mix hard water in the
coolant filled at the factory. An improp-
er coolant mixture can result in serious
malfunction or engine damage.
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.
