Engine temperature gauge
This gauge shows the temperature of the engine coolant when the igni-
tion switch is ON.
Fuel gauge
The fuel gauge indicates the approx-imate amount of fuel remaining in thefuel tank.
Do not continue driving with an
overheated engine. If your vehi-
cle overheats, refer to "If the
engine overheats" in section 6.
If the gauge pointer moves
beyond the normal range area
toward the red zone, it indicates
overheating that may damage
the engine.

ECO button again.
If Active ECO is turned off, it will return to the ECO mode.
When Active ECO is activated:
Vehicle speed may drop.
When driving up a hill, you mayfeel the engine torque change.
Limitation of Active ECO oper- ation :
If the following conditions occur while
Active ECO is operating, the system
operation is limited even thoughthere is no change in the ECO indi-
cator.
When the coolant temperature islow:The system will be limited until
engine performance becomes nor-mal.
When driving up a hill: The system will be limited to gain
power when driving uphill because
the engine torque is restricted. This is the switch of the PTO (Power
Take Off) which takes off the power
from the transmission.To activate the P.T.O. system
1.Stop the vehicle. Then, apply the
parking brake.
2.Depress the clutch pedal to dis- connect the power. Wait for 2 to 3

Driving your vehicle
Chains that are the wrong sizeor improperly installed can dam-
age your vehicle's brake lines,
suspension, body and wheels.
Stop driving and retighten the chains any time you hear them
hitting the vehicle.
Winter precautions
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 ofcoolant that should be used because
it helps prevent corrosion in the cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolantin accordance with the maintenance
schedule in section 7. Before winter,
have your coolant tested to assure
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 battery and cables as described
in section 7. We recommend that the
system be checked by an authorized
HYUNDAI dealer.
Change to "winter weight" oil ifnecessary
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, we recommend that you
consult an authorized HYUNDAI
dealer.
Check spark plugs and ignitionsystem
Inspect your spark plugs as
described in section 7 and replace
them if necessary. Also check all
ignition wiring and components to be
sure they are not cracked, worn or
damaged in any way.
NOTICE
Tire chains
The use of chains may
adversely affect vehicle han-dling.
Do not exceed 30 km/h (20
mph) or the chain manufactur-
er’s recommended speed
limit, whichever 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.

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 unexpectedly roll
down hill.However, if you ever have to park
your trailer on a hill, here's how to doit:
1. Pull the vehicle into the parking
space. Turn the steering wheel in
the direction of the curb (right if
headed down hill, left if headed uphill).
2. If the vehicle has a manual trans- mission, place the vehicle in neu-
tral.
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 chocksabsorb the load.
6. Reapply the brakes, reapply the parking brake and shift the vehicle
to R (Reverse) for manual trans-mission.
7. Shut off the vehicle and release the vehicle brakes but leave the
parking brake set.
When towing a trailer on steep
grades (in excess of 6%) pay
close attention to the engine
coolant temperature gauge toensure the engine does not
overheat. If the needle of the coolant
temperature gauge moves
across the dial towards “H”
(HOT), pull over and stop as
soon as it is safe to do so, and
allow the engine to idle until it
cools down. You may proceedonce the engine has cooled
sufficiently.
You must decide driving speed depending on trailerweight and uphill grade toreduce the possibility ofengine and transmission
overheating.
CAUTION
Parking on a hill
Parking your vehicle on a hill
with a trailer attached could
cause serious injury or death,
should the trailer break loose.

What to do in an emergency
5.Start the engine of the vehicle withthe booster battery and let it run at
2,000 rpm, then start the engine of
the vehicle with the discharged
battery.
If the cause of your battery discharg-
ing is not apparent, we recommendthat the system be checked by an authorized HYUNDAI dealer.
Push-starting
Your manual transmission-equipped
vehicle should not be push-startedbecause it might damage the emis-sion control system. If your temperature gauge indicates
overheating, you experience a loss
of power, or hear loud pinging or
knocking, the engine is probably too
hot. 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 neutral and set the parking brake. If the air con-
ditioning 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 oper-
ating. If the fan is not running, turn
the engine off.

Never tow a vehicle to start it
because the sudden surge for-
ward when the engine startscould cause a collision with the
tow vehicle.

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 leak-
ing from the radiator, hoses or
under the vehicle. (If the air condi-
tioning 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 bro-
ken or engine coolant is leakingout, stop the engine immediately
and we recommend that you call
an authorized HYUNDAI dealer. 6.If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to nor-
mal. Then, if coolant has been lost,carefully add coolant to the reser-
voir 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,
we recommend that you call an
authorized HYUNDAI dealer.
What to do in an emergency
While the engine is running,
keep hair, hands and clothing
away from moving parts suchas the fan and drive belts to pre-
vent injury.
WARNING
Do not remove the radiator cap
when the engine is hot. This can
allow coolant to be blown out ofthe opening and cause serious
burns.
WARNING
Serious loss of coolant indi- cates there is a leak in thecooling system and we rec-ommend that the system be
checked by an authorized
HYUNDAI dealer.
When the engine overheats
from low engine coolant, sud-
denly adding engine coolant
may cause cracks in the
engine. To prevent damage,
add engine coolant slowly insmall quantities.
CAUTION

Maintenance
Check the condition and connections of all cooling system hoses and
heater hoses. Replace any swollen
or deteriorated hoses.
The coolant level should be filled
between F and L marks on the side
of the coolant reservoir when theengine is cool.
If the coolant level is low, add enough
specified coolant to provide protec-tion against freezing and corrosion.
Bring the level to F, but do not over-
fill. If frequent additions are required,
we recommend that the system be
inspected by an authorized
HYUNDAI dealer.
Recommended engine coolant
When adding coolant, use onlydeionized water or soft water for
your vehicle and never mix hard
water in the coolant filled at the fac-
tory. An improper coolant mixture
can result in serious malfunction or
engine damage.
The engine in your vehicle has alu- minum engine parts and must be
protected by an ethylene-glycol-
based coolant to prevent corrosionand freezing.
DO NOT USE alcohol or methanol coolant or mix them with the spec-ified coolant.
Do not use a solution that contains more than 60% antifreeze or less
than 35% antifreeze, which would
reduce the effectiveness of thesolution.
The electric motor
(cooling fan) is con-
trolled by engine
coolant temperature,
refrigerant pressure
and vehicle speed. It may some-
times 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 theengine coolant temperature
decreases, the electric motor
will automatically shut off. Thisis a normal condition.WARNING

Radiator cap
Do not remove the radiator cap when the engine and radiator
are hot. Scalding hot coolant
and steam may blow out underpressure causing serious
injury.
WARNING
Put a thick cloth around the
radiator cap before refilling the
coolant in order to prevent the
coolant from overflowing into
engine parts such as the gener-
ator.
CAUTION
Coolant
Do not use radiator coolant or
antifreeze in the washer fluid
reservoir.
Radiator coolant can severely obscure visibility when
sprayed on the windshield
and may cause loss of vehicle
control or damage to paint
and body trim.
