If the risk of collision is detected while RCCW is generated, brake is controlled. The
instrument cluster will inform the driver of the brake control. If the rear view monitor
system is in activation, a message will also appear on the infotainment system screen.
After the brake control, the driver must immediately depress the brake pedal and
check the surroundings. - The brake activation by the system lasts for about 2 seconds. The driver must pay attention as the brake is disengaged after 2 seconds.

- The brake control by the system is cancelled if the driver depresses the brake pedal
with sufficient power.

- Brake control is activated once for each right/left approach after shifting the shift
button to R (Reverse).
The brake control may not operate properly according to the status of the ESC
(Electronic Stability Control). The same warning message is displayed on the
instrument cluster for this case also.
- When the ESC (Electronic Stability Control) warning light is on.

- When the ESC (Electronic Stability Control) is engaged in a different function.

CAUTION
• When the operation condition of
Rear Cross-Traffic Collision Warning
system is satisfied, the warning
will occur every time a vehicle
approaches the side or rear of your
stopped (0 mph (0 km/h) vehicle
speed) vehicle.
• The system’s warning or brake may
not operate properly if the left or
right of your vehicle’s rear bumper is
blocked by a vehicle or obstacle.
• The driver should always use
extreme caution while operating
the vehicle, whether or not the
warning light on the side view mirror
illuminates or there is a warning
alarm.
• Playing the vehicle audio system at
high volume may offset the system’s
warning sounds.
• The warning of Rear Cross-Traffic
Collision Warning System may not
sound while other system’s warning
sounds.
• If any other warning sound such as
seat belt warning chime is already
generated, Rear Cross-Traffic
Collision Warning system warning
may not sound.
WARNING
• Drive safely even though the vehicle
is equipped with Rear Cross-Traffic
Collision Warning system and Rear
Cross-Traffic Collision-Avoidance
Assist system. Do not solely rely
on the system but check your
surrounding when backing the
vehicle up.
• The driver is responsible for accurate
brake control.
• Always pay extreme caution while
driving. Rear Cross-Traffic Collision
Warning system and Rear Cross-
Traffic Collision-Avoidance Assist
system may not operate properly or
unnecessarily operate in accordance
with your driving situations.
• Rear Cross-Traffic Collision-
Avoidance Assist system is not a
substitute for safe driving practices,
but a convenience function only. It
is the responsibility of the driver to
always drive cautiously to prevent
unexpected and sudden situations
from occurring. Pay attention to the
road conditions at all times.

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, tire chains 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 35 mph (56
km/h).
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.
SPECIAL DRIVING CONDITIONS

While Driving6-134
Smooth Cornering
Avoid braking or gear changing in
corners, especially when roads are wet.
Ideally, corners should always be taken
under gentle acceleration.
Driving at Night
Night driving presents more hazards than
driving in the daylight. Here are some
important tips to remember:
• Slow down and keep more distance between you and other vehicles, as it
may be more difficult to see at night,
especially in areas where there may
not be any street lights.
• Adjust your mirrors to reduce the glare from other driver's headlamps.
• Keep your headlamps clean and properly aimed. Dirty or improperly
aimed headlamps will make it much
more difficult to see at night.
• Avoid staring directly at the headlamps of oncoming vehicles. You
could be temporarily blinded, and it
will take several seconds for your eyes
to readjust to the darkness.
Driving in the Rain
Rain and wet roads can make driving
dangerous. Here are a few things to
consider when driving in the rain or on
slick pavement:
• Slow down and allow extra following distance. A heavy rainfall makes
it harder to see and increases the
distance needed to stop your vehicle.
• Turn OFF your Cruise Control.
• Replace your windshield wiper blades when they show signs of streaking or
missing areas on the windshield.
• Tires should be properly maintained with at least 2/32nds of an inch of
tread depth. If your tires do not have
enough tread, making a quick stop on
wet pavement can cause a skid and
possibly lead to an accident. See "Tire
Tread" in chapter 8.
• Turn on your headlamps to make it easier for others to see you.
• Driving too fast through large puddles can affect your brakes. If you must go
through puddles, try to drive through
them slowly.
• If you believe your brakes may be wet, apply them lightly while driving until
normal braking operation returns.
Hydroplaning
If the road is wet enough and you are
going fast enough, your vehicle may
have little or no contact with the road
surface and actually ride on the water.
The best advice is SLOW DOWN when
the road is wet.
The risk of hydroplaning increases as
the depth of tire tread decreases, refer
to "Tire Tread" in chapter 8.
