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 traffic conditions.
On curves
The Smart Cruise Control system
may not detect a moving vehicle in
your lane, and then your vehicle
could accelerate to the set speed.
Also, the vehicle speed will
decrease when the vehicle ahead
is recognized suddenly.
Select the appropriate set speed
on curves and apply the brakes or
accelerator 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 condi-
tions permit safe operation of the
Smart Cruise Control.

Driving 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 rapidly
decrease when the vehicle ahead
is recognized suddenly.
Select the appropriate set speed
on inclines and apply the brake or
accelerator pedal if necessary.
Lane changing
A vehicle which moves into your
lane from an adjacent lane cannot
be recognized by the sensor until it
is in the sensor's detection range.
The radar may not detect immedi-
ately when a vehicle cuts in sud-
denly. Always pay attention to the
traffic, road and driving conditions.
If a slower vehicle moves into your
lane, your speed may decrease to
maintain the distance to the vehicle
ahead.
If a faster vehicle which moves into
your lane, your vehicle will acceler-
ate to the set speed.
Detecting vehicles
Some vehicles in your lane cannot
be recognized by the sensor:
- Narrow vehicles such as motorcy-
cles or bicycles
- Vehicles offset to one side
- Slow-moving vehicles or sudden-
decelerating vehicles
- Stopped vehicles
- Vehicles with small rear profile
such as trailers with no loads

A vehicle ahead cannot be recog-
nized correctly by the sensor if any of
following occurs:
- When the vehicle is pointing
upwards due to overloading in the
luggage compartment
- While the steering wheel is operat-
ing
- When driving to one side of the
lane
- When driving on narrow lanes or
on curves
Apply the brake or accelerator pedal
if necessary. Your vehicle may accelerate when
a vehicle ahead of you disappears.
When you are warned that the
vehicle ahead of you is not detect-
ed, drive with caution. When driving in stop-and-go traffic,
and a stopped vehicle in front of
you merges out of the lane, the
system may not immediately
detect the new vehicle that is now
in front of you. In this case, you
must maintain a safe braking dis-
tance, and if necessary, depress
the brake pedal to reduce your
driving speed in order to maintain a
safe distance.

Driving your vehicle
Always look out for pedestrians
when your vehicle is maintaining a
distance with the vehicle ahead. Always be cautious for vehicles
with higher height or vehicles car-
rying loads that sticks out from the
back of the vehicle.
OTLE058223OTM058124
When using the Smart Cruise
Control take the following pre-
cautions:
If an emergency stop is nec-
essary, you must apply the
brakes. The vehicle cannot be
stopped at every emergency
situation by using the Smart
Cruise Control system.
Keep a safe distance accord-
ing to road conditions and
vehicle speed. If the vehicle to
vehicle distance is too close
during a high-speed driving, a
serious collision may result.
Always maintain sufficient
braking distance and deceler-
ate your vehicle by applying
the brakes if necessary.
The Smart Cruise Control sys-
tem cannot recognize a
stopped vehicle, pedestrians or
an oncoming vehicle. Always
look ahead cautiously to pre-
vent unexpected and sudden
situations from occurring.

Information
The ESC system must be turned OFF
before rocking the vehicle.
If you are still stuck after rocking
the vehicle a few times, have the
vehicle pulled out by a tow vehicle
to avoid engine overheating, possi-
ble damage to the transmission,
and tire damage. See "Towing" in
chapter 6.
Smooth cornering
Avoid braking or gear changing in
corners, especially when roads are
wet. Ideally, corners should always
be taken under gentle acceleration.
Driving at night
Night driving presents more hazards
than driving in the daylight. Here are
some important tips to remember:
Slow down and keep more dis-
tance between you and other vehi-
cles, as it may be more difficult to
see at night, especially in areas
where there may not be any street
lights.
Adjust your mirrors to reduce the
glare from other driver's head-
lamps.
Keep your headlamps clean and
properly aimed. Dirty or improperly
aimed headlamps will make it
much more difficult to see at night.
Avoid staring directly at the head-
lamps of oncoming vehicles. You
could be temporarily blinded, and it
will take several seconds for your
eyes to readjust to the darkness.
Driving in the rain
Rain and wet roads can make driving
dangerous. Here are a few things to
consider when driving in the rain or
on slick pavement:
Slow down and allow extra follow-
ing distance. A heavy rainfall
makes it harder to see and increas-
es the distance needed to stop
your vehicle.
Turn OFF your Cruise Control.
Replace your windshield wiper
blades when they show signs of
streaking or missing areas on the
windshield.
Be sure your tires have enough
tread. If your tires do not have
enough tread, making a quick stop
on wet pavement can cause a skid
and possibly lead to an accident.
See "Tire replacement" in chap-
ter 7.
Turn on your headlamps to make it
easier for others to see you.
Driving too fast through large pud-
dles can affect your brakes. If you
must go through puddles, try to
drive through them slowly.

Driving your vehicle
- When using tire chains:
Wrong size chains or improperly
installed chains can damage
your vehicle's brake lines, sus-
pension, body and wheels.
Use SAE "S" class or wire
chains.
If you hear noise caused by
chains contacting the body,
retighten the chain to prevent
contact with the vehicle body.
To prevent body damage,
retighten the chains after driving
0.3~0.6 miles (0.5~1.0 km).
Do not use tire chains on vehi-
cles equipped with aluminum
wheels. If unavoidable, use a
wire type chain.
Use wire chains less than 0.59
inch (15 mm) wide to prevent
damage to the chain’s connec-
tion.
Winter Precautions
Use high quality ethylene glycol
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 chapter 7. Before winter,
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.
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
chapter 8 for recommendations. If
you aren't sure what weight oil you
should use, consult an authorized
HYUNDAI dealer.
Check battery and cables
Winter puts additional burdens on
the battery system. Visually inspect
the battery and cables as described
in chapter 7. The level of charge in
your battery can be checked by an
authorized HYUNDAI dealer or a
service station.

Check spark plugs and ignition
system
Inspect your spark plugs as
described in chapter 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.
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.
Do not let your parking brake
freeze
Under some conditions your parking
brake can freeze in the engaged
position. This is most likely to happen
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 selector lever in P
and block the rear wheels so the car
cannot roll. Then release the parking
brake.
Do not 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.
Don't place foreign objects or
materials in the engine com-
partment
Placement of foreign object or mate-
rials which prevent cooling of the
engine, in the engine compartment,
may cause a failure or combustion.
The manufacturer is not responsible
for the damage caused by such
placement.
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.

Trailer towing equipment
Hitches
It's important to have the correct
hitch equipment. Crosswinds, large
trucks going by, and rough roads are
a few reasons why you’ll need the
right hitch. Here are some rules to
follow:
Do you have to make any holes in
the body of your vehicle when you
install a trailer hitch? If you do, then
be sure to seal the holes later
when you remove the hitch. If you
don’t seal them, carbon monoxide
(CO) from your exhaust can get
into your vehicle, as well as dirt
and water.
The bumpers on your vehicle are
not intended for hitches. Do not
attach rental hitches or other
bumper-type hitches to them. Use
only a frame-mounted hitch that
does not attach to the bumper.
A HYUNDAI trailer hitch accessory
is available at an authorized
HYUNDAI dealer.
