Limitations of the system
The smart cruise control system may
have limits to its ability to detect distance
to the vehicle ahead due to road and traf-
fic conditions.
On curves
• On curves, the smart cruise control
system may not detect a moving vehi-
cle in your lane, and then your vehicle
could accelerate to the set speed. Also,
the vehicle speed will slow down when
the vehicle ahead is recognized sud-
denly.
• Select the appropriate set speed on
curves and apply the brakes or accel-
erator pedal if necessary.• Your vehicle speed can be reduced
due to a vehicle in the adjacent lane.
Apply the accelerator pedal and select
the appropriate set speed. Check to be
sure that the road conditions permit
safe operation of the smart cruise con-
trol.

CAUTION
• Do not install accessories around
the sensor and do not replace the
bumper by yourself. It may inter-
fere with the sensor performance.
• Always keep the sensor and
bumper clean.
• To prevent sensor cover damage
from occurring, wash the car with
a soft cloth.
• Do not damage the sensor or sen-
sor area by a strong impact. If the
sensor moves slightly off posi-
tion, the smart cruise control sys-
tem will not operate correctly.
If this occurs, have your vehicle
checked by an authorized
HYUNDAI dealer as soon as pos-
sible.
• Use only a genuine HYUNDAI
sensor cover for your vehicle.

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 loads

Driving your vehicle
A 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.(Continued)
• The smart cruise control system
is not a substitute for safe driving
practices but a convenience
function only. It is the responsi-
bility of the driver to always
check the speed and the distance
to the vehicle ahead.
• Always be aware of the selected
speed and vehicle to vehicle dis-
tance.
• Always maintain sufficient brak-
ing distance and decelerate your
vehicle by applying the brakes if
necessary.
• As the smart cruise control sys-
tem may not recognize complex
driving situations, always pay
attention to driving conditions
and control your vehicle speed.
• For safe operation, carefully read
and follow the instructions in this
manual before use.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.
(Continued)
CAUTION
The smart cruise control system
may not operate temporarily due to
electrical interference.

VSM detects the distance from the vehi-
cle ahead with the sensor, to warn you
before collision and protect you in certain
hazardous situations.• If the VSM senses the object ahead too
near the vehicle and if driver's operat-
ing of the brake pedal or the steering
wheel should be needed, the warning
light illuminates.
Immediately reduce your speed.
• If the VSM senses more dangerous,
the warning sound also operates and
the accelerator pedal/seat belt
vibrates. Immediately reduce your
speed.
VEHICLE STABILITY MANAGEMENT (VSM) (IF EQUIPPED)
CAUTION
Always check the road conditions
to prevent danger even if the warn-
ing light does not illuminate, the
warning sound does not operate or
the accelerator pedal/seat belt does
not vibrate.

Brake operating
• If the VSM senses the collision, the
brake system comes to standard mode
to react promptly when the driver oper-
ates the brake pedal.
• If the driver releases the accelerator
after warning in hazardous situations,
the VSM automatically brakes the vehi-
cle gently.
• If the driver hits the brake to reduce
vehicle speed, the brake assistant sys-
tem operates to raise efficiency of
braking.
• If danger disappears, if the driver
depresses the accelerator or if the driv-
er releases the brake pedal, the brake
operating stop.
Seat belt operating
The seat belt tightens when the vehicle
senses a collision.
To cancel the VSM
• If you press the VSM OFF button, the
warning operating and brake operating
will cancel and the VSM OFF indicator
illuminates on the instrument cluster.
To turn on the VSM, press the VSM
OFF button again. The VSM OFF indi-
cator goes out.
• If you press the ESP OFF button to
turn off the ESP, the VSM will cancel,
too.
WARNING
The VSM does not stop the vehicle
completely and does not avoid col-
lision. Always look ahead cautious-
ly to prevent unexpected and sud-
den situations from occurring.
WARNING
The VSM operates according to the
distance from the vehicle ahead,
relative velocity and driver's opera-
tion of the brake or accelerator
pedal. Do not drive dangerously to
operate the VSM.

Malfunction indicator
• The VSM OFF indicator will illuminate
when the engine start/stop button is
turned ON, but should go off after
approximately 3 seconds. If the indica-
tor does not come on, or continuously
remains on after coming on for about 3
seconds when you turn the engine
start/stop button to the ON position, or
if the indicator comes on while driving,
the VSM is not working properly. Take
your vehicle to an authorized
HYUNDAI dealer and have the system
checked.
• The VSM OFF indicator may illuminate
when the ESP indicator or SCC indica-
tor comes on, but it does not indicate
malfunction of the VSM.
OVI059067
WARNING
The VSM is not a substitute for safe
driving practices but a supplemen-
tary function only. It is the respon-
sibility of the driver to always check
the speed and the distance to the
vehicle ahead.
WARNING
• Even if there is a malfunction to
the brake operating of the VSM,
when you depress the brake
pedal, the brake is operating nor-
mally. But, the VSM brake operat-
ing does not operate even in cer-
tain hazardous situations.
• The VSM is designed to function
above approximately 15 km/h (9.3
mph) and below approximately
180 km/h (111.8 mph).
• The VSM does not react to
- Persons or animals.
- Oncoming vehicles in the oppo-
site lane or the vehicle in the
intersection.
- Stopped objects.
• The VSM can not detect the
objects certainly, when:
- The sensors are stained with
dirt or covered.
- There is heavy rain or heavy
snow.
- There is interference by electro-
magnetic waves.

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.
• 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.
ECONOMICAL OPERATION

555
Driving your vehicle
• 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.
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 transmis-
sion. Do not race the engine, and spin
the wheels as little as possible. If you are
still stuck after a few tries, have the vehi-
cle pulled out by a tow vehicle to avoid
engine overheating and possible dam-
age to the transmission.
SPECIAL DRIVING CONDITIONS
OVI059043
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.
