Driving your vehicle

Your vehicle's fuel economy depends
mainly on your style of driving, where
you drive and when you drive.
Each of these factors affects how
many miles (kilometers) you can get
from a gallon (liter) of fuel. To operate
your vehicle as economically as pos-
sible, use the following driving sug-
gestions to help save money in both
fuel and repairs:
• Drive smoothly. Accelerate at a
moderate rate. Don't make "jack-
rabbit" starts or full-throttle shifts
and maintain a steady cruising
speed. Don't race between stop-
lights. Try to adjust your speed to
that of the other traffic so you don't
have to change speeds unneces-
sarily. Avoid heavy traffic whenever
possible. Always maintain a safe
distance from other vehicles so
you can avoid unnecessary brak-
ing. This also reduces brake wear.
• Drive at a moderate speed. The
faster you drive, the more fuel your
car uses. Driving at a moderate
speed, especially on the highway,
is one of the most effective ways to
reduce fuel consumption.• Don't "ride" the brake pedal. This
can increase fuel consumption and
also increase wear on these com-
ponents. In addition, driving with
your foot resting on the brake pedal
may cause the brakes to overheat,
which reduces their effectiveness
and may lead to more serious con-
sequences.
• Take care of your tires. Keep them
inflated to the recommended pres-
sure. Incorrect inflation, either too
much or too little, results in unnec-
essary tire wear. Check the tire
pressures at least once a month.
• Be sure that the wheels are
aligned correctly. Improper align-
ment can result from hitting curbs
or driving too fast over irregular
surfaces. Poor alignment causes
faster tire wear and may also result
in other problems as well as
greater fuel consumption.• Keep your car in good condition.
For better fuel economy and
reduced maintenance costs, main-
tain your car in accordance with
the maintenance schedule in sec-
tion 7. If you drive your car in
severe conditions, more frequent
maintenance is required (see sec-
tion 7 for details).
• Keep your car clean. For maximum
service, your vehicle should be
kept clean and free of corrosive
materials. It is especially important
that mud, dirt, ice, etc. not be
allowed to accumulate on the
underside of the car. This extra
weight can result in increased fuel
consumption and also contribute to
corrosion.
• Travel lightly. Don't carry unneces-
sary weight in your car. Weight
reduces fuel economy.
• Don't let the engine idle longer
than necessary. If you are waiting
(and not in traffic), turn off your
engine and restart only when
you're ready to go.

Hazardous driving conditions
When hazardous driving conditions
are encountered such as water,
snow, ice, mud, sand, or similar haz-
ards, follow these suggestions:
• Drive cautiously and allow extra
distance for braking.
• Avoid sudden movements in brak-
ing or steering.• If stalled in snow, mud, or sand,
use second gear. Accelerate slow-
ly to avoid spinning the drive
wheels.
• Use sand, rock salt, tire chains, or
other non-slip material under the
drive wheels to provide traction
when stalled in ice, snow, or mud.
Rocking the vehicle
If it is necessary to rock the vehicle
to free it from snow, sand, or mud,
first turn the steering wheel right and
left to clear the area around your
drive wheels. Then, shift back and
forth between R (Reverse) and any
forward gear in vehicles equipped
with an automatic transmission. Do
not race the engine, and spin the
wheels as little as possible. If you are
still stuck after a few tries, have the
vehicle pulled out by a tow vehicle to
avoid engine overheating and possi-
ble damage to the transmission.
SPECIAL DRIVING CONDITIONS
OVI053043
WARNING- ABS
Do not pump the brake pedal on
a vehicle equipped with ABS.
WARNING
- Downshifting
Downshifting with an automatic
transmission, while driving on
slippery surfaces can cause an
accident. The sudden change in
tire speed could cause the tires
to skid. Be careful when down-
shifting on slippery surfaces.
CAUTION
Prolonged rocking may cause
engine over-heating, transmis-
sion damage or failure, and tire
damage.

Fuel, engine coolant and engine
oil
High speed travel consumes more
fuel than urban motoring. Do not for-
get to check both engine coolant and
engine oil.
Drive belt
A loose or damaged drive belt may
result in overheating of the engine.
WARNING
• Underinflated or overinflated
tires can cause poor handling,
loss of vehicle control, and
sudden tire failure leading to
accidents, injuries, and even
death. Always check tires for
proper inflation before driv-
ing. For proper tire pressures,
refer to “Tires and wheels” in
section 8.
• Driving on tires with no or
insufficient tread is danger-
ous. Worn-out tires can result
in loss of vehicle control, col-
lisions, injury, and even death.
Worn-out tires should be
replaced as soon as possible
and should never be used for
driving. Always check the tire
tread before driving your car.
For further information and
tread limits, refer to “Tires and
wheels” in section 7.

What to do in an emergency
5.Start the engine of the vehicle with
the 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 recommend
that you have your vehicle checked
by an authorized HYUNDAI dealer.
Push-starting
Vehicles equipped with automatic
transmission cannot be push-start-
ed.
Follow the directions in this section
for jump-starting.CAUTION - Battery
cables
If you jump start the discharged
battery in the trunk compart-
ment, do not connect the
jumper cable from the negative
terminal of the booster battery
to the negative terminal of the
discharged battery. This can
cause the discharged battery to
overheat and crack, releasing
battery acid.
Connect the jumper cable from
the negative terminal of the
booster battery to a solid, sta-
tionary or metallic point away
from the discharged battery.

IF THE ENGINE OVERHEATS
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 P and set
the parking brake. If the air condi-
tioning 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 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 satis-
factory, check for coolant leaking
from the radiator, hoses or under
the vehicle. (If the air conditioning
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 bro-
ken or engine coolant is leaking
out, we recommend that you 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
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 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 pre-
vent injury.
CAUTION
• Serious loss of coolant indi-
cates there is a leak in the
cooling system and we recom-
mend that the system be
checked as soon as possible
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 in
small quantities.
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.

• Use a towing strap less than 5 m
(16 feet) long. Attach a white or red
cloth (about 30 cm (12 inches)
wide) in the middle of the strap for
easy visibility.
• Drive carefully so that the towing
strap is not loosened during tow-
ing.
Emergency towing precautions
• Place the engine start/stop button
in ACC so the steering wheel isn’t
locked.
• Place the transmission shift lever in
N (Neutral).
• Release the parking brake.
• Press the brake pedal with more
force than normal since you will
have reduced brake performance.
• More steering effort will be
required because the power steer-
ing system will be disabled.
• If you are driving down a long hill,
the brakes may overheat and brake
performance will be reduced. Stop
often and let the brakes cool off.WARNING
Use extreme caution when tow-
ing the vehicle.
• Avoid sudden starts or erratic
driving maneuvers which
would place excessive stress
on the emergency towing
hook and towing cable or
chain. The hook and towing
cable or chain may break and
cause serious injury or dam-
age.
• If the disabled vehicle is
unable to be moved, do not
forcibly continue the towing.
We recommend that you con-
tact an authorized HYUNDAI
dealer or a commercial tow
truck service for assistance.
• Tow the vehicle as straight
ahead as possible.
• Keep away from the vehicle
during towing.

Maintenance
ENGINE COOLANT
The high-pressure cooling system
has a reservoir filled with year-round
antifreeze coolant. The reservoir is
filled at the factory.
Check the antifreeze protection and
coolant level at least once a year, at
the beginning of the winter season,
and before traveling to a colder cli-
mate.Checking the coolant level
WARNING
Removing radiator
cap
• Never attempt to remove the
radiator cap while the engine
is operating or hot. Doing so
might lead to cooling system
and engine damage and could
result in serious personal
injury from escaping 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 while
the pressure is released from
the cooling system.
(Continued)
(Continued)
When you are sure all the
pressure has been released,
press down on the cap, using
a thick towel, and continue
turning counterclockwise to
remove it.
• Even if the engine is not oper-
ating, do not remove the radi-
ator 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.
CAUTION
• 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 in
small quantities.
• Do not drive with no engine
coolant. It may cause water
pump failure and engine
seizure, etc.
