Frontal air bags are not designed to
inflate in rear collisions, because occu-
pants are moved backward by the
force of the impact. In this case, inflat-
ed air bags would not be able to pro-
vide any additional benefit. Front air bags may not inflate in side
impact collisions, because occupants
move to the direction of the collision,
and thus in side impacts, frontal air bag
deployment would not provide addi-tional occupant protection.
However, side impact and curtain air
bags may inflate depending on the
intensity, vehicle speed and angles ofimpact. 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 bene-
fit, and thus the sensors may not
deploy any air bags.

Safety features of your vehicle
Just before impact, drivers often brakeheavily. 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 signifi-
cantly reduced by such “under-ride”
collisions. Air bags may not inflate in rollover acci-
dents because air bag deployment
would not provide protection to the
occupants.
However, side impact and curtain air bags may inflate when the vehicle is
rolled over by a side impact collision, if
the vehicle is equipped with side
impact air bags and curtain air bags. Air bags may not inflate if the vehicle
collides with objects such as utility
poles or trees, where the point of
impact is concentrated to one area and
the full force of the impact is not deliv-
ered to the sensors.

Features of your vehicle
Inside rearview mirror
Adjust the rearview mirror to centre on
the view through the rear window. Make
this adjustment before you start driving.
Day/night rearview mirror
Make this adjustment before you start
driving and whilst the day/night lever is in
the day position.
Pull the day/night lever toward you to reduce the glare from the headlights of
the vehicles behind you during night driv-ing.
Remember that you lose some rearviewclarity in the night position.
Electric chromic mirror (ECM)
(if equipped)
The electric chromic mirror automatically controls the glare from the headlights of
the car behind you in nighttime or low
light driving conditions. The sensormounted in the mirror senses the light
level around the vehicle, and automati-cally controls the headlight glare from
vehicles behind you.
When the engine is running, the glare is
automatically controlled by the sensor
mounted in the rearview mirror.
Whenever the shift lever is shifted into R
(Reverse), the mirror will automatically
go to the brightest setting in order to
improve the drivers view behind the vehi-
cle.
MIRRORS
CAUTION
When cleaning the mirror, use a
paper towel or similar material dampened with glass cleaner. Do not spray glass cleaner directly onthe mirror as that may cause the liq-
uid cleaner to enter the mirror hous-ing.
WARNING - Rear visibility
Do not place objects in the rear
seat or cargo area which would
interfere with your vision through
the rear window.

CAUTION
Do not scrape ice off the mirror
face; this may damage the surface
of the glass. If ice should restrict movement of the mirror, do notforce the mirror for adjustment. To remove ice, use a deicer spray, or a
sponge or soft cloth with very warmwater.
CAUTION
If the mirror is jammed with ice, do not adjust the mirror by force. Usean approved spray de-icer (not radi-
ator antifreeze) to release thefrozen mechanism or move thevehicle to a warm place and allow the ice to melt.
WARNING
Do not adjust or fold the outside
rearview mirrors whilst the vehicle
is moving. This could result in loss
of control, and an accident which
could cause death, serious injury
or property damage.
WARNING - Rearview mir-
rors
The right outside rearview mirror is convex. In some countries, the
left outside rearview mirror is
also convex. Objects seen in the
mirror are closer than they
appear.
Use your interior rearview mirror or direct observation to deter-
mine the actual distance of fol-
lowing vehicles when changinglanes.

Features of your vehicle
The rear parking assist system assists
the driver during backward movement of
the vehicle by chiming if any object issensed within a distance of 120 cm (47
in.) behind the vehicle. This system is asupplemental system and it is not intend-
ed to nor does it replace the need for
extreme care and attention of the driver.
The sensing range and objects
detectable by the back sensors are limit-
ed. Whenever backing-up, pay as much
attention to what is behind you as you
would in a vehicle without a rear parkingassist system.Operation of the rear parking assist system
Operating condition
This system will activate when backing
up with the ignition switch ON.
The sensing distance whilst the rear parking assist system is in operation is
approximately 120 cm (47 in.).
When more than two objects are sensed at the same time, the closest
one will be recognized first.
Types of warning sound
When an object is 120 cm to 81 cm (47in. to 32 in.) from the rear bumper:
Buzzer beeps intermittently.
When an object is 80 cm to 41 cm (31 in. to 16 in.) from the rear bumper:
Buzzer beeps more frequently.
When an object is within 40 cm (15 in.) of the rear bumper:
Buzzer sounds continuously.

Non-operational conditions of rear parking assist system
The rear parking assist system may
not operate properly when:
1. Moisture is frozen to the sensor. (It will
operate normally when the moisture has been cleared.)
2. The sensor is covered with foreign matter, such as snow or water, or the
sensor cover is blocked. (It will operate
normally when the material is removed
or the sensor is no longer blocked.)
3. Driving on uneven road surfaces (unpaved roads, gravel, bumps, gradi-ent).
4. Objects generating excessive noise (vehicle horns, loud motorcycle
engines, or truck air brakes) are within
range of the sensor.
5. Heavy rain or water spray exists.
6. Wireless transmitters or mobile phones are within range of the sensor.
7. The sensor is covered with snow.
8. Trailer towing The detecting range may decrease when:
1. The sensor is stained with foreign mat-
ter such as snow or water. (The sens-
ing range will return to normal when
removed.)
2. Outside air temperature is extremely hot or cold.
The following objects may not be rec-
ognized by the sensor:
1. Sharp or slim objects such as ropes, chains or small poles.
2. Objects which tend to absorb the sen- sor frequency such as clothes, spongy
material or snow.
3. Undetectable objects smaller than 1 m (40 in.) in height and narrower than 14
cm (6 in.) in diameter. Rear parking assist system pre- cautions
The rear parking assist system may
not sound sequentially depending on the speed and shapes of the objectsdetected.
The rear parking assist system may malfunction if the vehicle bumperheight or sensor installation has been
modified or damaged. Any non-factory
installed equipment or accessories
may also interfere with the sensor per-
formance.
The sensor may not recognize objects less than 40 cm (15 in.) from the sen-
sor, or it may sense an incorrect dis-
tance. Use caution.
When the sensor is frozen or stained with snow, dirt, or water, the sensor
may be inoperative until the stains are
removed using a soft cloth.
Do not push, scratch or strike the sen- sor. Sensor damage could occur.

Features of your vehicle
✽✽NOTICE
This system can only sense objects with-
in the range and location of the sensors;
It can not detect objects in other areas
where sensors are not installed. Also,
small or slim objects, such as poles or
objects located between sensors may not
be detected by the sensors.
Always visually check behind the vehi-
cle when backing up.
Be sure to inform any drivers of the
vehicle that may be unfamiliar with the
system regarding the systems capabili-
ties and limitations.Self-diagnosis
If you don’t hear an audible warning
sound or if the buzzer sounds intermit-tently when shifting the gear to the R
(Reverse) position, this may indicate a
malfunction in the rear parking assist sys-
tem. If this occurs, have your vehicle
checked by an authorised HYUNDAI
dealer as soon as possible.
WARNING
Pay close attention when the vehi-
cle is driven close to objects on the
road, particularly pedestrians, and
especially children. Be aware that
some objects may not be detected
by the sensors, due to the object’s
distance, size or material, all of
which can limit the effectiveness of
the sensor. Always perform a visu-al inspection to make sure the vehi-
cle is clear of all obstructions
before moving the vehicle in anydirection.
WARNING
Your new vehicle warranty does not
cover any accidents or damage to
the vehicle or injuries to its occu-pants due to a rear parking assist
system malfunction. Always drive
safely and cautiously.
