Driving your vehicle
84 5
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.
ECONOMICAL OPERATION

Driving your vehicle
• Remember, your vehicle does not
require extended warm-up. After
the engine has started, allow the
engine to run for 10 to 20 seconds
prior to placing the vehicle in gear.
In very cold weather, however, give
your engine a slightly longer warm-
up period.
• Don't "lug" or "over-rev" the engine.
Lugging is driving too slowly in too
high a gear resulting in the engine
bucking. If this happens, shift to a
lower gear. Over-revving is racing
the engine beyond its safe limit.
This can be avoided by shifting at
the recommended speeds.
• Use your air conditioning sparingly.
The air conditioning system is
operated by engine power so your
fuel economy is reduced when you
use it.
• Open windows at high speeds can
reduce fuel economy.
• Fuel economy is less in crosswinds
and headwinds. To help offset
some of this loss, slow down when
driving in these conditions.Keeping a vehicle in good operating
condition is important both for econ-
omy and safety. Therefore, we rec-
ommend that the system be serviced
by an authorized HYUNDAI dealer.
WARNING - Engine off
during
motion
Never turn the engine off to
coast down hills or anytime the
vehicle is in motion. The power
steering and power brakes will
not function properly without
the engine running. Instead,
keep the engine on and down-
shift to an appropriate gear for
engine braking effect. In addi-
tion, turning off the ignition
while driving could engage the
steering wheel lock resulting in
loss of vehicle steering which
could cause serious injury or
death.

What to do in an emergency
8 6
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.

OWNER MAINTENANCE
The following lists are vehicle checks
and inspections that should be per-
formed at the frequencies indicated
to help ensure safe, dependable
operation of your vehicle.
Any adverse conditions should be
brought to the attention of your deal-
er as soon as possible.
These Owner Maintenance Checks
are generally not covered by war-
ranties and you may be charged for
labor, parts and lubricants used.Owner maintenance schedule
When you stop for fuel:
• Check the engine oil level.
• Check coolant level in coolant
reservoir.
• Check the windshield washer fluid
level.
• Look for low or under-inflated tires.
While operating your vehicle:
• Note any changes in the sound of
the exhaust or any smell of
exhaust fumes in the vehicle.
• Check for vibrations in the steering
wheel. Notice any increased steer-
ing effort or looseness in the steer-
ing wheel, or change in its straight-
ahead position.
• Notice if your vehicle constantly
turns slightly or “pulls” to one side
when traveling on smooth, level
road.
• When stopping, listen and check
for unusual sounds, pulling to one
side, increased brake pedal travel
or “hard-to-push” brake pedal.
• If any slipping or changes in the
operation of your transmission
occurs, check the transmission
fluid level.
• Check automatic transmission P
(Park) function.
• Check parking brake.
• Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal).
WARNING
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot
coolant and steam may blow
out under pressure. This could
cause burns or other serious
injury.
