or decelerates when the highway speed limit changes.
• If your vehicle speed exceeds 153 km/h
(95 mph), Highway Driving Assist
is automatically canceled. Also, it is
converted to Smart Cruise Control automatically with a pop-up message on the navigation.
• If you enter a rest area on the highway
or a IC/JC (intersection/junction) without a destination set, the system is
canceled later than when the vehicle
actually leaves the highway.

The options for the initial Rear Cross-
Traffic Collision Warning includes the
following:
- Normal: When this condition is selected, the
initial Rear Cross-Traffic Collision
Warning is activated normally. If this
setting feels sensitive, change the
option to ‘Later’.
The warning activation time may feel
late if the a vehicle at the side or rear
abruptly accelerates.
- Later: Select this warning activation time
when the traffic is light and you are
driving at a low speed.
Information
If you change the warning timing, the
warning time of other systems may
change. Always be aware before changing the warning timing.
The driver can select the warning volume
of Rear Cross-Traffic Collision Warning
by selecting ‘User Settings → Driver
Assistance → Warning Volume → High/
Medium/Low’.
Information
If you change the warning volume, the
warning volume of other systems may
change. Always be aware before changing the warning volume. Operating conditions
To operate:
Go to the “User Settings → Driver
Assistance → Parking Safety → Rear Cross-
Traffic Safety” on the LCD display or
infotainment system display. The system
will turn on and standby to activate.
The system will activate when vehicle
speed is below 10 km/h (7 mph) and with
the shift button in R (Reverse). 
The system will not activate when
the vehicle speed exceeds 10 km/h (7
mph). The system will activate again
when the speed is below 8 km/h (5
mph).
The system’s detecting range is
approximately 0.5 ~ 20 m (1 ~ 65 ft). An
approaching vehicle will be detected if
their vehicle speed is within 8 ~ 36 km/h
(5 ~ 22.5 mph).
Note that the detecting range and
operating speed may vary under certain
conditions. As always, use caution and
pay close attention to your surroundings
when backing up your vehicle.

Hazardous Driving Conditions
When hazardous driving elements
are encountered such as water, snow,
ice, mud and sand, take the below
suggestions: • Drive cautiously and keep a longer
braking distance.
• Avoid abrupt braking or steering.
• When your vehicle is stuck in
snow, mud, or sand, use second
gear. Accelerate slowly to avoid unnecessary wheel spin.
• Put sand, rock salt or other non-slip
materials under the wheels to provide
additional traction while the vehicle
becomes stuck in ice, snow, or mud.
WARNING
Downshifting with an automatic
transmission while driving on slippery
surfaces can cause an accident. The
sudden change in tire speed could
cause the tires to skid. Be careful when
downshifting on slippery surfaces.
Rocking the Vehicle
If it is necessary to rock the vehicle to
free it from snow, sand, or mud, first turn
the steering wheel right and left to clear
the area around your front wheels. Then,
shift back and forth between R (Reverse)
and a forward gear.
Try to avoid spinning the wheels, and do
not race the engine.
To prevent transmission wear, wait until
the wheels stop spinning before shifting
gears. Release the accelerator pedal
while shifting, and press lightly on the
accelerator pedal while the transmission
is in gear. Slowly spinning the wheels in
forward and reverse directions causes a
rocking motion that may free the vehicle.
WARNING
If the vehicle is stuck and excessive
wheel spin occurs, the temperature
of the tires can increase very quickly.
If the tires become damaged, a tire
blow out or tire explosion can occur.
This condition is dangerous - you and
others may be injured. Do not attempt
this procedure if people or objects are
anywhere near the vehicle.
If you attempt to free the vehicle, the
vehicle can overheat quickly, possibly
causing an engine compartment fire
or other damage. Try to avoid spinning
the wheels as much as possible to
prevent overheating of either the tires
or the engine. DO NOT allow the vehicle
to spin the wheels above 56 km/h (35
mph).
Information
The ESC system must be turned OFF
before rocking the vehicle.
NOTICE
If you are still stuck after rocking the
vehicle a few times, have the vehicle
pulled out by a tow vehicle to avoid
engine overheating, possible damage to
the transmission, and tire damage. See
"Towing" in chapter 7.
