In an angled collision, the force of
impact may direct the occupants in a
direction where the air bags would
not be able to provide any additional
benefit, and thus the sensors may
not deploy any air bags.Just before impact, drivers often
brake heavily. Such heavy braking
lowers the front portion of the vehicle
causing it to "ride" under a vehicle
with a higher ground clearance. Air
bags may not inflate in this "under-
ride" situation because deceleration
forces that are detected by sensors
may be significantly reduced by such
"underride" collisions.Front air bags may not inflate in
rollover accidents because air bag
deployment could not provide protec-
tion to the occupants.
However, side and curtain air bags
may inflate when the vehicle is rolled
over by a side impact collision.

Convenient features of your vehicle
Non-operational conditions ofParking Assist System
The Rear Parking Assist System
may not operate normally when:
Moisture is frozen to the sensor.
The sensor is covered with dirt or
debris such as snow or ice, or the
sensor cover is blocked.
There is a possibility of the Rear
Parking Assist System malfunction
when:
Driving on uneven road surfacessuch as unpaved roads, gravel,
bumps, or gradient.
Objects generating excessive noise such as vehicle horns, loud motor-
cycle engines, or truck air brakes
can interfere with the sensor.
Heavy rain or water spray is present.
Wireless transmitters or mobile phones are present near the sensor.
The sensor is covered with snow.
Any non-factory equipment or accessories have been installed, or
if the vehicle bumper height or sen-
sor installation has been modified.
Detecting range may decrease when:
Outside air temperature isextremely hot or cold.
Undetectable objects smaller than 40 inches (1 m) and narrower than
6 inches (14 cm) in diameter.
The following objects may not be
recognized by the sensor:
Sharp or slim objects such asropes, chains or small poles.
Objects, which tend to absorb sen- sor frequency such as clothes,
spongy material or snow.

The AEB is only a supplemen-
tal system for the driver’s con-
venience. The driver should
hold the responsibility to con-
trol the vehicle operation. Do
not solely depend on the AEB
system. Rather, maintain a
safe braking distance, and, if
necessary, depress the brake
pedal to reduce the driving
speed.
In certain instances and
under certain driving condi-
tions, the AEB system may
activate prematurely. This ini-
tial warning message appears
on the LCD display with a
warning chime.
Also, in certain instances the
front radar sensor or camera
recognition system may not
detect the vehicle or pedestri-
an ahead. The AEB system
may not activate and the
warning message will not be
displayed.(Continued)
(Continued)
If there is a malfunction with
the AEB system, the automat-
ic emergency braking is not
applied even though the brak-
ing system is operating nor-
mally.
The AEB system operates
only to help detect vehicles or
pedestrians in front of the
vehicle.
The AEB system does not
operate when the vehicle is in
reverse.
The AEB system is not
designed to detect other
objects on the road such as
animals.
The AEB system does not
detect cross traffic vehicles
that are approaching.
The AEB system cannot
detect the driver approaching
the side view of a parked vehi-
cle (for example on a dead
end street.)
(Continued)
(Continued)In these cases, you must
maintain a safe braking dis-
tance, and if necessary,
depress the brake pedal to
reduce the driving speed in
order to maintain a safe dis-
tance.WARNING

Driving your vehicle
- Driving on a curve
The performance of the AEB system
may be limited when driving on a
curved road.
In certain instances on a curved
road, the AEB system may activate
prematurely.
Also, in certain instances the front
radar sensor or camera recognition
system may not detect the vehicle
traveling on a curved road.
In these cases, the driver must main-
tain a safe braking distance, and if
necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance.- Driving on a slope
The performance of the AEB
decreases while driving upward or
downward on a slope, not recogniz-
ing the vehicle in front in the same
lane. It may unnecessarily produce
the warning message and the warn-
ing alarm, or it may not produce the
warning message and the warning
alarm at all.
When the AEB suddenly recognizes
the vehicle 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.

Exterior care
Exterior general caution
It is very important to follow the label
directions when using any chemical
cleaner or polish. Read all warning
and caution statements that appear
on the label.
High-pressure washing
When using high-pressure wash-
ers, make sure to maintain suffi-
cient distance from the vehicle.
Insufficient clearance or excessive
pressure can lead to component
damage or water penetration.
Do not spray the camera, sensors or its surrounding area directly with
a high pressure washer. Shock
applied from high pressure water
may cause the device to not oper-
ate normally.
Do not bring the nozzle tip close to boots (rubber or plastic covers)or
connectors as they may be dam-
aged if they come into contact with
high pressure water.
Do not use any high-pressure noz- zles, which induce either one-direct
water stream or water swirling.
Protecting your vehicle's finish
Washing
To help protect your vehicle’s finish
from rust and deterioration, wash it
thoroughly and frequently at least
once a month with lukewarm or cold
water.
If you use your vehicle for off-road
driving, you should wash it after each
off-road trip. Pay special attention to
the removal of any accumulation of
salt, dirt, mud, and other foreign
materials. Make sure the drain holes
in the lower edges of the doors and
rocker panels are kept clear and
clean.
Insects, tar, tree sap, bird droppings,
industrial pollution and similar
deposits can damage your vehicle’s
finish if not removed immediately.
Even prompt washing with plain
water may not completely remove all
these deposits. A mild soap, safe for
use on painted surfaces, should be
used.
After washing, rinse the vehicle thor-
oughly with lukewarm or cold water.
Do not allow soap to dry on the fin-
ish. After washing the vehicle, test
the brakes while driving slowly
to see if they have been affected
by water before getting on the
road. If braking performance is
impaired, dry the brakes by
applying them lightly while
maintaining a slow forward
speed.
