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 gal-
lon (liter) of fuel. To operate your vehicle
as economically as possible, use the fol-
lowing driving suggestions to help save
money in both fuel and repairs:
Drive smoothly. Accelerate at a moder-
ate rate. Don't make "jack-rabbit" starts
or full-throttle shifts and maintain a
steady cruising speed. Don't race
between stoplights. 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 dis-
tance from other vehicles so you can
avoid unnecessary braking. This also
reduces brake wear.
Drive at a moderate speed. The faster you drive the more fuel your vehicle
uses. Driving at a moderate speed, in
the highest gear appropriate for the
conditions, especially on the highway,
is one of the most effective ways to
reduce fuel consumption. Don't "ride" the brake or clutch 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 consequences.
Take care of your tires. Keep them inflated to the recommended pressure.
Incorrect inflation, either too much or
too little, results in unnecessary tire
wear. Check the tire pressures at least
once a month.
Be sure that the wheels are aligned correctly. Improper alignment can
result from hitting curbs or driving too
fast over irregular surfaces. Poor align-
ment 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, maintain your car
in accordance with the maintenance
schedule in section 7. If you drive your
car in severe conditions, more frequent
maintenance is required (see section 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 con-
sumption and also contribute to corro-
sion.
Travel lightly. Don't carry unnecessary 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 hazards, follow
these suggestions:
Drive cautiously and allow extra dis-
tance for braking.
Avoid sudden movements in braking or steering. When braking with non-ABS brakes
pump the brake pedal with a light up-
and-down motion until the vehicle is
stopped.
If stalled in snow, mud, or sand, use second gear. Accelerate slowly 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.
E110200ATQ
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 possible damage to the transmission
SPECIAL DRIVING CONDITIONS
OBK059019
WARNING - ABS
Do not pump the brake pedal on a
vehicle equipped with ABS.
WARNING - Downshifting
Downshifting with an automatic
transmission, while driving on slip-
pery surfaces can cause an acci-
dent. The sudden change in tire
speed could cause the tires to skid.
Be careful when downshifting on
slippery surfaces.
CAUTION
Prolonged rocking may causeengine over-heating, transmission damage or failure, and tire damage.

Highway driving
Tires
Adjust the tire inflation pressures to
specification. Low tire inflation pressures
will result in overheating and possible
failure of the tires.
Avoid using worn or damaged tires which
may result in reduced traction or tire fail-
ure.
✽ ✽NOTICE
Never exceed the maximum tire inflation
pressure shown on the tires.
Fuel, engine coolant and engine oil
High speed travel consumes more fuel
than urban motoring. Do not forget 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 sud-
den tire failure leading to acci-
dents, injuries, and even death.
Always check tires for proper
inflation before driving. For prop-
er tire pressures, refer to “Tires
and wheels” in section 8.
Driving on tires with no or insuffi- cient tread is dangerous. Worn-
out tires can result in loss of
vehicle control, collisions, 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.

Jump starting procedure
1. Make sure the booster battery is 12-volt and that its negative terminal is
grounded.
2. If the booster battery is in another vehicle, do not allow the vehicles to
touch.
3. Turn off all unnecessary electrical loads.
4. Connect the jumper cables in the exact sequence shown in the illustration.
First connect one end of a jumper
cable to the positive terminal of the
discharged battery (1), then connect
the other end to the positive terminal
on the booster battery (2).
Proceed to connect one end of the
other jumper cable to the negative ter-
minal of the booster battery (3), then
the other end to a solid, stationary,
metallic point (for example, the engine
lifting bracket) away from the battery
(4). Do not connect it to or near any
part that moves when the engine is
cranked.
Do not allow the jumper cables to con-
tact anything except the correct battery
terminals or the correct ground. Do not
lean over the battery when making
connections. 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 vehi-
cle with the discharged battery.
If the cause of your battery discharging isnot apparent, you should have your vehi-cle checked by an authorized HYUNDAI dealer.
F040200ABK
Push-starting
Your manual transmission-equipped
vehicle should not be push-started
because it might damage the emission
control system.
Vehicles equipped with automatic trans-
mission cannot be push-started.
Follow the directions in this section for
jump-starting.
WARNING
Never tow a vehicle to start it
because the sudden surge forward
when the engine starts could cause
a collision with the tow vehicle.
CAUTION- Battery cables
Do not connect the jumper cablefrom the negative terminal of thebooster battery to the negative ter-minal of the discharged battery.This can cause the discharged bat- tery to overheat and crack, releas-ing battery acid.

IF THE ENGINE OVERHEATS
F050000ABK
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 itis safe to do so.
2. Place the shift lever in P (automatic transmission) or neutral (manual trans-
mission) 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
underneath the hood, stop the engine.
Do not open the hood until the coolant
has flow 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. 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 may
result in 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 authorizedHYUNDAI dealer.
