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 Systemmay 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.
Do not install accessories
around the radar and do not
replace the bumper by your-
self. It may interfere with the
radar performance.
Always keep the radar and
bumper clean.
To prevent radar cover dam-
age from occurring, wash the
car with a soft cloth.
Do not paint the radar cover.
Do not damage the radar or
radar area by a strong impact.
If the radar moves slightly off
position, the Smart Cruise
Control System will not oper-
ate correctly. If this occurs,
have your vehicle checked by
an authorized HYUNDAI deal-
er.
Use only a genuine HYUNDAI
radar cover for your vehicle.

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 con-
ditions permit safe operation of the
Smart Cruise Control.
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 yourlane from an adjacent lane cannot
be recognized by the radar until it
is in the radar'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.
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 con-
ditions permit safe operation of the
Smart Cruise Control.

Some vehicles in your lane cannot
be recognized by the radar:
- 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 radar if any of
following occurs:
- When the vehicle is pointing
upwards due to overloading in the
trunk
- While the steering wheel is operat- ing
- When driving to one side of the lane
- When driving on narrow lanes or on curves

cautions:
If an emergency stop is nec-
essary, you must apply the
brakes. The vehicle cannot be
stopped by using the Smart
Cruise Control System.
Keep a safe distance accord-
ing to road conditions and

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 drive cautiously
to prevent unexpected and
sudden situations from occur-
ring.
Always be aware of the select-
ed speed and vehicle to vehi-
cle distance.
The Smart Cruise Control
System may not recognize
complex driving situations so

FCWS malfunction message
When the FCWS is not working
properly, the warning message will
come on for a few second. After the
message disappears, the master
warning light will illuminate.
Limitations of the System
The Forward Collision Warning
System may have limits to its ability
to detect distance to the vehicle
ahead due to road and traffic condi-
tions.
The FCW cannot detect objects,
when:
- The camera lens is covered withdirt.
- There is heavy rain or heavy snow.
- Driving in a curve.
- Driving uphill or downhill.
- An object ahead is very narrow such as motorcycles or bicycles.
- A vehicle suddenly enters your lane.
- The front vehicle suddenly departs from the lane or it is hidden by other
objects.
- A vehicle passes by at a higher rate of speed.
The Forward Collision Warning
System is a supplemental sys-
tem to assist you and its
effects may differ according to
road and driving conditions.
Do not solely rely on the sys-
tem and always pay attention
to prevent dangerous situa-
tions from occurring.
FCWS is a warning system and
does not apply the brakes
automatically in a near crash
situation. FCWS may not pro-
vide a warning with enough
time to help avoid a crash.
FCWS does not detect pedes-
trians, animals, signs, con-
struction or other objects. It is
the responsibility of the driver
to pay attention to the roadway
to prevent collisions.

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. (if equipped)
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.
Refer to "Tire Tread" in chapter 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. If you believe your brakes may be
wet, apply them lightly while driv-
ing until normal braking operation
returns.
Hydroplaning
If the road is wet enough and you are
going fast enough, your vehicle may
have little or no contact with the road
surface and actually ride on the
water. The best advice is SLOW
DOWN when the road is wet. The
risk of hydroplaning increases as the
depth of tire tread decreases. (Refer
to "Tire Tread" in chapter 7.)
Driving in Flooded Areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel
hub. Drive through any water slowly.
Allow adequate stopping distance
because brake performance may be
reduced.
After driving through water, dry the
brakes by gently applying them sev-
eral times while the vehicle is moving
slowly.
