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

585
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.

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.

Driving your vehicle
More severe weather conditions of
winter result in greater wear and
other problems. To minimize winter
driving problem, you should follow
these suggestions:
Snowy or icy conditions
To drive your vehicle in deep snow, it
may be necessary to use snow tires
or to install tire chains on your tires.
If snow tires are needed, it is neces-
sary to select tires equivalent in size
and type of the original equipment
tires. Failure to do so may adversely
affect the safety and handling of your
car. Furthermore, speeding, rapid
acceleration, sudden brake applica-
tions, and sharp turns are potentially
very hazardous practices.
During deceleration, use engine
braking to the fullest extent. Sudden
brake applications on snowy or icy
roads may cause skids to occur. You
need to keep sufficient distance
between the vehicle in operation in
front and your vehicle. Also, apply
the brake gently. It should be noted
that installing tire chains on the tire
will provide a greater driving force,
but will not prevent side skids.
✽NOTICE
Tire chains are not legal in all coun-
tries. Check the country laws before
fitting tire chains.
Snow tires
If you mount snow tires on your vehi-
cle, make sure they are radial tires of
the same size and load range as the
original tires. Mount snow tires on all
four wheels to balance your vehicle’s
handling in all weather conditions.
Keep in mind that the traction provid-
ed by snow tires on dry roads may
not be as high as your vehicle's orig-
inal equipment tires. You should drive
cautiously even when the roads are
clear. Check with the tire dealer for
maximum speed recommendations.
Do not install studded tires without
first checking local, state and munic-
ipal regulations for possible restric-
tions against their use.
WINTER DRIVING
WARNING- Snow tire
size
Snow tires should be equivalent
in size and type to the vehicle's
standard tires. Otherwise, the
safety and handling of your
vehicle may be adversely affect-
ed.

245/50R18 Tire chains
Since the sidewalls of radial tires are
thinner, they can be damaged by
mounting some types of snow chains
on them. Therefore, the use of snow
tires is recommended instead of
snow chains. Do not mount tire
chains on vehicles equipped with
aluminum wheels; snow chains may
cause damage to the wheels. If snow
chains must be used, use wire-type
chains with a thickness of less than
12 mm (0.47 in). Damage to your
vehicle caused by improper snow
chain use is not covered by your
vehicle manufacturers warranty.
Install tire chains only on the rear
tires.Chain installation
When installing chains, follow the
manufacturer's instructions and
mount them as tightly as you can.
Drive slowly with chains installed. If
you hear the chains contacting the
body or chassis, stop and tighten
them. If they still make contact, slow
down until it stops. Remove the
chains as soon as you begin driving
on cleared roads.
CAUTION
• Make sure the snow chains
are the correct size and type
for your tires. Incorrect snow
chains can cause damage to
the vehicle body and suspen-
sion and may not be covered
by your vehicle manufacturer
warranty. Also, the snow chain
connecting hooks may be
damaged from contacting
vehicle components causing
the snow chains to come
loose from the tire. Make sure
the snow chains are SAE
class “S” certified.
• Always check chain installa-
tion for proper mounting after
driving approximately 0.5 to 1
km (0.3 to 0.6 miles) to ensure
safe mounting. Retighten or
remount the chains if they are
loose.
WARNING
- Mounting chains
When mounting snow chains,
park the vehicle on level ground
away from traffic. Turn on the
vehicle Hazard Warning flashers
and place a triangular emer-
gency warning device behind
the vehicle if available. Always
place the vehicle in P (Park),
apply the parking brake and
turn off the engine before
installing snow chains.

Chain installation
When installing the AutoSock (fabric
snow chain), follow the manufactur-
er's instructions and mount them as
tightly as you can. Drive slowly with
the AutoSock (fabric snow chain)
installed. If you hear the AutoSock
(fabric snow chain) contacting the
body or chassis, stop and tighten
them. If they still make contact, slow
down until it stops. Remove the
AutoSock (fabric snow chain) as
soon as you begin driving on cleared
roads.Use high quality ethylene gly-
col 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 cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in 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. The level of charge in
your battery can be checked by an
authorized HYUNDAI dealer or a
service station.CAUTION
• The AutoSock (fabric snow
chain) that are the wrong size
or improperly installed can
damage your vehicle's brake
lines, suspension, body and
wheels.
• Stop driving and retighten the
AutoSock (fabric snow chain)
any time you hear them hitting
the vehicle.
WARNING - Tire chains
• The use of the AutoSock (fab-
ric snow chain) may adversely
affect vehicle handling.
• Do not exceed 30 km/h (20
mph) or the AutoSock (fabric
snow chain) manufacturer’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.
WARNING
- Mounting chains
When mounting the AutoSock
(fabric snow chain), park the
vehicle on level ground away
from traffic. Turn on the vehicle
Hazard Warning flashers and
place a triangular emergency
warning device behind the vehi-
cle if available. Always place the
vehicle in P (Park), apply the
parking brake and turn off the
engine before installing the
AutoSock (fabric snow chain).

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 authorized
HYUNDAI dealer.
Check spark plugs and igni-
tion system
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.
To keep locks from freezing
To keep the locks from freezing,
squirt an approved de-icer fluid or
glycerine into the key opening. If a
lock is covered with ice, squirt it with
an approved de-icing fluid to remove
the ice. If the lock is frozen internally,
you may be able to thaw it out by
using a heated key. Handle the heat-
ed key with care to avoid injury.
Use approved window washer
anti-freeze in system
To keep the water in the window
washer system from freezing, add an
approved window washer anti-freeze
solution in accordance with instruc-
tions on the container. Window wash-
er anti-freeze is available from an
authorized HYUNDAI dealer and
most auto parts outlets. Do not use
engine coolant or other types of anti-
freeze as these may damage the
paint finish.
Don't let your parking brake
freeze
Under some conditions your parking
brake can freeze in the engaged
position. This is most likely to hap-
pen when there is an accumulation
of snow or ice around or near the
rear brakes or if the brakes are wet.
If there is a risk the parking brake
may freeze, apply it only temporarily
while you put the gear shift lever in P
and block the rear wheels so the
vehicle cannot roll. Then release the
parking brake.
Don't let ice and snow accu-
mulate underneath
Under some conditions, snow and
ice can build up under the fenders
and interfere with the steering. When
driving in severe winter conditions
where this may happen, you should
periodically check underneath the
car to be sure the movement of the
front wheels and the steering com-
ponents is not obstructed.
