[A] : Structure, [B] : Wall
• Pulling into the parking space
where there is a structure
The system may not operate prop-
erly when pulling in the vehicle to
the parking space where there is a
structure at the back or side of your
vehicle.
In certain instances, when backing
into the parking space, the system
may falsely detect the vehicle mov-
ing in front of your vehicle. In this
case, the warning or brake may
operate.
Always pay attention to the parking
space while driving.• When the vehicle is parked rear-
ward
If the vehicle is parked rearward
and the sensor detects the another
vehicle in the rear area of the park-
ing space, the system can warn or
control braking. Always pay atten-
tion to the parking space while
driving.

Operating conditions
Parking Collision-Avoidance Assist-
Reverse system enters the ready
status, when 'Active Assist' or
'Warning Only' is selected in the AVN
system screen and the following con-
ditions are satisfied:
• The trunk is closed
• The shift lever is in R (Reverse)
• Vehicle speed is below 6 mph (10
km/h)
• System components such as the
rear view camera and the rear
ultrasonic sensors are in normal
conditions
The driver needs to select 'Active
Assist' on the AVN system screen for
collision-avoidance assist.
The solid lines behind the vehicle in
the cluster LCD display indicates that
the system is ready to assist the driv-
er.
Note that the system assists the driver
only once. The driver has to shift the
gear to R (Reverse) from another gear
position to reactivate the system.
The performance of the Parking
Collision Avoidance Assist-Reverse
system may vary under certain con-
ditions. If the vehicle speed exceeds
2 mph (3 km/h), the system can
assist only pedestrian collision avoid-
ance.
As always, be careful when backing
up your vehicle and be aware of your
surroundings.
Warning and System Control
Active assist
• If the system detects a risk of colli-
sion with a pedestrian or an object
behind the vehicle, the system will
warn the driver with audible warning,
steering wheel vibration, and warn-
ings on the cluster LCD display and
the AVN system screen.
• If the system detects imminent col-
lision with a pedestrian or an object
behind the vehicle, the system may
apply braking power. The driver
needs to pay attention as the brake
will release within 2 seconds. The
driver must immediately depress
the brake pedal and check sur-
roundings.

To temporarily accelerate with
the Smart Cruise Control on
If you want to speed up temporarily
when the Smart Cruise Control is on,
depress the accelerator pedal.
Increased speed will not interfere
with Smart Cruise Control operation
or change the set speed.
To return to the set speed, take your
foot off the accelerator pedal.
If you push the toggle switch down
(SET-) at increased speed, the cruis-
ing speed will be set again.
Information

porarily, because the speed is not con-
trolled automatically at this time even
if there is a vehicle in front of you.
Smart Cruise Control will be
temporarily canceled when:
Canceled manually
• Depressing the brake pedal.
• Pushing the CANCEL button locat-
ed on the steering wheel.

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 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

ing
- When driving to one side of the
lane

Changing a Tire with TPMS
If you have a flat tire, the Low Tire
Pressure and LCD position indicator
will come on. Have the flat tire
repaired by an authorized retailer of
Genesis Branded products as soon
as possible or replace the flat tire
with the spare tire.
Never use a puncture-repairing
agent not approved by authorized
retailer of Genesis Branded prod-
ucts to repair and/or inflate a low
pressure tire. Tire sealant not
approved by authorized retailer of
Genesis Branded products may
damage the tire pressure sensor.
The spare tire does not come with a
tire pressure monitoring sensor.
When the low pressure tire or the flat
tire is replaced with the spare tire,
the Low Tire Pressure LCD position
indicator will remain on. Also, the
TPMS Malfunction Indicator will illu-
minate after blinking for one minute if
the vehicle is driven at speed above
15.5 mph (25 km/h) for approximate-
ly 20 minutes.
Once the original tire equipped with
a tire pressure monitoring sensor is
reinflated to the recommended pres-
sure and reinstalled on the vehicle,
the Low Tire Pressure LCD position
indicator and TPMS Malfunction
Indicator will go off within a few min-
utes of driving.
If the indicators do not disappear
after a few minutes, please visit an
authorized retailer of Genesis
Branded products.Each wheel is equipped with a tire
pressure sensor mounted inside the
tire behind the valve stem (except for
the spare tire). You must use TPMS
specific wheels. It is recommended
that you always have your tires serv-
iced by an authorized retailer of
Genesis Branded products.
You may not be able identify a tire
with low pressure by simply looking
at it. Always use a good quality tire
pressure gage to measure the tire's
inflation pressure. Please note that a
tire that is hot (from being driven) will
have a higher pressure measure-
ment than a tire that is cold.
A cold tire means the vehicle has
been sitting for 3 hours and driven for
less than 1 mile (1.6 km) in that 3
hour period.
Allow the tire to cool before measur-
ing the inflation pressure. Always be
sure the tire is cold before inflating to
the recommended pressure.
NOTICE
• The TPMS cannot alert you to
severe and sudden tire dam-
age caused by external fac-
tors such as nails or road
debris.
• If you feel any vehicle instabil-
ity, immediately take your foot
off the accelerator, apply the
brakes gradually with light
force, and slowly move to a
safe position off the road.
WARNING

• Do not tow the vehicle with the
rear wheels on the ground as
this may cause damage to the
vehicle.
• Do not tow with sling-type equip-
ment. Use a wheel lift or flatbed
equipment.When towing your vehicle in an
emergency without wheel dollies:
1. Release EPB before turning off
the engine.
2. Press the Engine Start/Stop but-
ton to the OFF position.
3. Change the gear to N (Neutral) by
pressing the P release button
(need to remove cap-cover) while
pressing the brake pedal.
For more details, refer to
"Automatic Transmission –
When the Battery is Discharged"
in chapter 5.
Failure to place the shift lever in N
(Neutral) when being towed with
the front wheels on the ground
can cause internal damage to the
transmission.
NOTICE
NOTICE
If your vehicle is equipped with
a rollover sensor, place the
Engine Start/Stop button in the
OFF position. The side impact
and curtain air bag may deploy
if the sensor detects the situa-
tion as a rollover.
