the appropriate set speed. Check to be
sure that the road conditions permit
safe operation of the smart cruise con-
trol.E150902ABH
On inclines
• During uphill or downhill driving, the
smart cruise control system may not
detect a moving vehicle in your lane,
and cause your vehicle to accelerate to
the set speed. Also, the vehicle speed
will slow down when the vehicle ahead
is recognized suddenly.
• Select the appropriate set speed on
inclines and apply the brakes or accel-
erator pedal if necessary.

Lane changing
• A vehicle which moves into your lane
from an adjacent lane cannot be rec-
ognized by the sensor until it is in the
sensor's detection range.
• The sensor may not detect immediate-
ly when a vehicle cuts in suddenly.
Always pay attention to the traffic, road
and driving conditions.
• If a vehicle which moves into your lane
is slower than your vehicle, your speed
may decrease to maintain the distance
to the vehicle ahead.
• If a vehicle which moves into your lane
is faster than your vehicle, your vehicle
will accelerate to the selected speed.

Vehicle recognition
Some vehicles ahead in your lane cannot
be recognized by the sensor as follows:
- Narrow vehicles such as motorcycles or
bicycles
- Vehicles offset to one side
- Slow-moving vehicles or sudden-decel-
erating vehicles
- Stopped vehicles
- Vehicles with small rear profile such as
trailers with no loadsA vehicle ahead cannot be recognized
correctly by the sensor if any of following
occurs:
- When the vehicle is pointing upwards
due to overloading in the trunk
- While the steering wheel is operating
- When driving to one side of the lane
- When driving on narrow lanes or on
curves
Apply the brakes or accelerator pedal if
necessary.
WARNING
• The vehicle cannot be stopped by
using the smart cruise control
system.
If an emergency stop is neces-
sary, you must apply the brakes.
• Keep a safe distance according
to road conditions and vehicle
speed. If the vehicle to vehicle
distance is too close during a
high-speed driving, it may cause
a serious collision.
• The smart cruise control system
can not recognize a stopped
vehicle, pedestrians or an
oncoming vehicle. Always look
ahead cautiously to prevent
unexpected and sudden situa-
tions from occurring.
• In front of you, vehicles moving
with a frequent lane change may
cause a delay in the system's
reaction or may cause the system
to react to a vehicle actually in an
adjacent lane. Always look ahead
cautiously to prevent unexpected
and sudden situations from
occurring.

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 car uses.
Driving at a moderate speed, especial-
ly on the highway, is one of the most
effective ways to reduce fuel consump-
tion.• Don't "ride" the brake pedal. This can
increase fuel consumption and also
increase wear on these components.
In addition, driving with your foot rest-
ing 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.
ECONOMICAL OPERATION

Driving your vehicle
60 5
• 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 plac-
ing 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 avoid-
ed by shifting at the recommended
speeds.• Use your air conditioning sparingly.
The air conditioning system is operat-
ed by engine power so your fuel econ-
omy 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 con-
dition is important both for economy and
safety. Therefore, have an authorized
HYUNDAI dealer perform scheduled
inspections and maintenance.
WARNING - Engine off dur-
ing 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 run-
ning. Instead, keep the engine on
and downshift to an appropriate
gear for engine braking effect. In
addition, 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 hazards, follow
these suggestions:
• Drive cautiously and allow extra dis-
tance for braking.
• Avoid sudden movements in braking or
steering.• 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
OBH058034
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 cause
engine over-heating, transmission
damage or failure, and tire damage.

563
Driving your vehicle
• Adjust your mirrors to reduce the glare
from other driver's headlights.
• Keep your headlights clean and prop-
erly aimed on vehicles not equipped
with the automatic headlight aiming
feature. Dirty or improperly aimed
headlights will make it much more diffi-
cult to see at night.
• Avoid staring directly at the headlights
of oncoming vehicles. You could be
temporarily blinded, and it will take
several seconds for your eyes to read-
just to the darkness.

Driving in the rain
Rain and wet roads can make driving
dangerous, especially if you’re not pre-
pared for the slick pavement. Here are a
few things to consider when driving in the
rain:
• A heavy rainfall will make it harder to
see and will increase the distance
needed to stop your vehicle, so slow
down.
• Keep your windshield wiping equip-
ment in good shape. Replace your
windshield wiper blades when they
show signs of streaking or missing
areas on the windshield.• If your tires are not in good condition,
making a quick stop on wet pavement
can cause a skid and possibly lead to
an accident. Be sure your tires are in
good shape.
• Turn on your headlights to make it eas-
ier for others to see you.
• Driving too fast through large puddles
can affect your brakes. If you must go
through puddles, try to drive through
them slowly.
• If you believe you may have gotten
your brakes wet, apply them lightly
while driving until normal braking oper-
ation returns.

Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no high-
er than the bottom of the wheel hub.
Drive through any water slowly. Allow
adequate stopping distance because
brake performance may be affected.
After driving through water, dry the
brakes by gently applying them several
times while the vehicle is moving slowly.
Driving off-road
Drive carefully off-road because your
vehicle may be damaged by rocks or
roots of trees. Become familiar with the
off-road conditions where you are going
to drive before you begin driving.E110700ABH
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.

More severe weather conditions of winter
result in greater wear and other prob-
lems. To minimize winter driving problem,
you should follow these suggestions:
E120100AUN
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 necessary to select
tires equivalent in size and type of the
original equipment tires. Failure to do so
may adversely affect the safety and han-
dling of your car. Furthermore, speeding,
rapid acceleration, sudden brake appli-
cations, and sharp turns are potentially
very hazardous practices.
During deceleration, use engine braking
to the fullest extent. Sudden brake appli-
cations on snowy or icy roads may cause
skids to occur. You need to keep suffi-
cient 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 countries.
Check the country laws before fitting
tire chains.
E120101AUN
Snow tires
If you mount snow tires on your vehicle,
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 provided by snow tires on dry
roads may not be as high as your vehi-
cle's original equipment tires. You should
drive cautiously even when the roads are
clear. Check with the tire dealer for max-
imum speed recommendations.
Do not install studded tires without first
checking local, state and municipal regu-
lations for possible restrictions against
their use.
WINTER DRIVING
WARNING- Snow tire size
Snow tires should be equivalent in
size and type to the vehicle's stan-
dard tires. Otherwise, the safety
and handling of your vehicle may
be adversely affected.

Tire chains
Since the sidewalls of radial tires are
thinner, they can be damaged by mount-
ing some types of snow chains on them.
Therefore, the use of snow tires is rec-
ommended 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 manufactur-
ers warranty.
Install tire chains only on the rear tires.Chain installation
When installing chains, follow the manu-
facturer'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 suspension and may not be
covered by your vehicle manufac-
turer 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 installation
for proper mounting after driving
approximately 0.5 to 1 km (0.3 to
0.6 miles) to ensure safe mount-
ing. 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 emergency warning
device behind the vehicle if avail-
able. Always place the vehicle in P
(Park), apply the parking brake and
turn off the engine before installing
snow chains.
