Driving your vehicle
Driving on a slope
The performance of Forward
Collision-Avoidance Assist system
may be decreased while driving
upward or downward on a slope.
The front view camera or front
radar sensor recognition may not
detect the vehicle, pedestrian or
cyclist in front.
This may result in unnecessary
alarm and braking or no alarm and
braking when necessary.
When the system suddenly recog-
nizes the vehicle, pedestrian or
cyclist in front while passing over a
slope, you may experience sharp
deceleration.Always keep your eyes forward
while driving upward or downward
on a slope, and, if necessary,
depress the brake pedal to reduce
your driving speed in order to
maintain distance.
Changing lanes
When a vehicle changes lanes in
front of you, Forward Collision-
Avoidance Assist system may not
immediately detect the vehicle,
especially if the vehicle changes
lanes abruptly. 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.

When driving in stop-and-go traffic,
and a vehicle in front of you merges
out of the lane, Forward Collision-
Avoidance Assist 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 dis-
tance. Detecting the vehicle in front of you
If the vehicle in front of you has
cargo that extends rearward from
the cab, or when the vehicle in
front of you has higher ground
clearance, additional special atten-
tion is required. Forward Collision-
Avoidance Assist system may not
be able to detect the cargo extend-
ing from the vehicle. In these
instances, you must maintain a
safe braking distance from the
rearmost object, and if necessary,
depress the brake pedal to reduce
your driving speed in order to
maintain distance.
Detecting pedestrians or
cyclists
The sensor may be limited when:
The pedestrian or cyclist is not fully
detected by the front view camera
recognition system, for example, if
the pedestrian is leaning over or is
not fully walking upright
The pedestrian or cyclist is moving
very quickly or appears abruptly in
the front view camera detection
area
The pedestrian or cyclist is wear-
ing clothing that easily blends into
the background, making it difficult
to be detected by the front view
camera recognition system
The outside lighting is too bright
(e.g. when driving in bright sunlight
or in sun glare) or too dark (e.g.
when driving on a dark rural road
at night)
It is difficult to detect and distin-
guish the pedestrian or cyclist from
other objects in the surroundings,
for example, when there is a group
of pedestrians, cyclists or a large
crowd

porarily when the Set Speed and
Vehicle-to-Vehicle Distance indicator
on the cluster LCD display turns off.
The cruise ( ) indicator is
illuminated continuously.Cancelled automatically
The driver's door is opened.
The shift lever is shifted to N
(Neutral), R (Reverse) or P (Park).

TCS (Traction Control System) or
ABS is operating.
ESC is turned off.
The sensor or the cover is dirty or
blocked with foreign matter.

Driving your vehicle
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
Smart Cruise Control.
On inclines
During uphill or downhill driving,
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.

Vehicle recognition
Some vehicles in your lane cannot
be recognized by the sensor:
- Vehicles offset to one side
- Slow-moving vehicles or sudden-
decelerating vehicles
- Stopped vehicles
- Vehicles with small rear profile
such as trailers with no loadsA 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.

Smart Cruise Control is basical-
ly designed to set vehicles as a
target. Always look ahead cau-
tiously to cope with unexpected
situations such as a collision
when the system sets an object
as a target, not vehicles.
WARNING

6-22
What to do in an emergency
When towing your vehicle in an
emergency without wheel dollies:
1. While depressing the brake pedal
shift to the N (Neutral) position
and turn the vehicle off. The
POWER button will be in the ACC
position.
2. Release the parking brake.
Failure to shift to N (Neutral) may
cause internal damage to the vehi-
cle.
Removable Towing Hook
1. Open the liftgate, and remove the
towing hook from the tool case.
2. Remove the hole cover by press-
ing the lower part of the cover on
the front or rear bumper.
3. Install the towing hook by turning it
clockwise into the hole until it is
fully secured.
4. Remove the towing hook and
install the cover after use.
NOTICE
If your vehicle is equipped with
a rollover sensor, place the
POWER button in the OFF or
ACC position when the vehicle
is being towed. The side impact
and curtain air bag may deploy
if the sensor detects the situa-
tion as a rollover.
