DRIVING AND OPERATING 189
{Warning
Using the brakes to slow the vehicle
on a long downhill slope can cause
brake overheating, can reduce brake
performance, and could result in a
loss of braking. Shift the
transmission to a lower gear to let
the engine assist the brakes on a
steep downhill slope.
{Warning
Coasting downhill in N (Neutral) or
with the ignition off is dangerous.
This can cause overheating of the
brakes and loss of steering. Always
have the engine running and the
vehicle in gear.
. Drive at speeds that keep the
vehicle in its own lane. Do not
swing wide or cross the
center line.
. Be alert on top of hills; something
could be in your lane (e.g., stalled
car, accident). .
Pay attention to special road signs
(e.g., falling rocks area, winding
roads, long grades, passing or
no-passing zones) and take
appropriate action.
Winter Driving
Driving on Snow or Ice
Snow or ice between the tires and the
road creates less traction or grip, so
drive carefully. Wet ice can occur at
about 0 °C (32 °F) when freezing rain
begins to fall. Avoid driving on wet ice
or in freezing rain until roads can be
treated.
For slippery road driving:
.Accelerate gently. Accelerating too
quickly causes the wheels to spin
and makes the surface under the
tires slick.
. Turn on Traction Control. See
Traction Control/Electronic Stability
Control 0208.
. Antilock Brake System (ABS)
improves vehicle stability during
hard stops, but the brakes should be applied sooner than when on
dry pavement. See
Antilock Brake
System (ABS) 0205.
See Driver Mode Control 0209
. Allow greater following distance
and watch for slippery spots. Icy
patches can occur on otherwise
clear roads in shaded areas. The
surface of a curve or an overpass
can remain icy when the
surrounding roads are clear. Avoid
sudden steering maneuvers and
braking while on ice.
. Turn off cruise control.
Blizzard Conditions
Stop the vehicle in a safe place and
signal for help. Stay with the vehicle
unless there is help nearby. Get help
and keep everyone in the vehicle safe:
.Turn on the hazard warning
flashers.
. Tie a red cloth to an outside
mirror.

CRC - 6/21/16
DRIVING AND OPERATING 221
Do not use ACC when driving on steep
hills or when towing a trailer. For
towing capability, seeGeneral Towing
Information 0243. ACC will not detect
a vehicle in the lane while driving on
steep hills. The driver will often need
to take over acceleration and braking
on steep hills, especially when towing
a trailer. If the brakes are applied, the
ACC disengages.
Disengaging ACC
There are three ways to
disengage ACC:
. Step lightly on the brake pedal.
. Press
*.
. Press
J. Erasing Speed Memory
The ACC set speed is erased from
memory if
Jis pressed or if the
ignition is turned off.
Cleaning the Sensing System
The camera sensor on the windshield
behind the rearview mirror and the
radar sensors on the front of the
vehicle can become blocked by snow,
ice, dirt, or mud. These areas need to
be cleaned for ACC to operate
properly.
For cleaning instructions, see
“Washing the Vehicle ”under Exterior
Care 0301.
System operation may also be limited
under snow, heavy rain, or road spray
conditions.
Driver Assistance
Systems
This vehicle may have features that
work together to help avoid crashes or
reduce crash damage while driving,
backing, and parking. Read this entire
section before using these systems.
{Warning
Do not rely on the Driver
Assistance Systems. These systems
do not replace the need for paying
attention and driving safely. You
may not hear or feel alerts or
warnings provided by these
systems. Failure to use proper care
when driving may result in injury,
death, or vehicle damage. See
Defensive Driving 0185.
Under many conditions, these
systems will not: . Detect children, pedestrians,
bicyclists, or animals.

complete before continuing the
parking maneuver. APA will beep and
display a PARKING COMPLETE
message. Place the vehicle in P (Park).
APA may automatically disengage if:
.The steering wheel is used by the
driver.
. The maximum allowed speed is
exceeded.
. There is a failure with the APA
system.
. Electronic stability control or
antilock brakes are activated.
. A high priority vehicle message is
displayed in the DIC.
To cancel APA, touch
Oagain.
When the System Does Not Seem to
Work Properly
The APA system may require a short
period of driving along curves to
calibrate.
Assistance Systems for
Driving
If equipped, when driving the vehicle
in a forward gear, Forward Collision
Alert (FCA), Lane Departure Warning
(LDW), Lane Keep Assist (LKA), Side
Blind Zone Alert (SBZA), Lane Change
Alert (LCA), the Forward Automatic
Braking (FAB) system, the Front
Pedestrian Braking (FPB) system and/
or the Night Vision system can help to
avoid a crash or reduce crash damage.
Forward Collision Alert
(FCA) System
If equipped, the FCA system may help
to avoid or reduce the harm caused by
front-end crashes. When approaching
a vehicle ahead too quickly, FCA
provides a red flashing alert on the
windshield and rapidly beeps or pulses
the driver seat. FCA also lights an
amber visual alert if following another
vehicle much too closely.
FCA detects vehicles within a distance
of approximately 60 m (197 ft) and
operates at speeds above 8 km/h
(5 mph). If the vehicle has Adaptive Cruise Control (ACC), it can detect
vehicles to distances of approximately
110 m (360 ft) and operates at all
speeds. See
Adaptive Cruise
Control 0213.
{Warning
FCA is a warning system and does
not apply the brakes. When
approaching a slower-moving or
stopped vehicle ahead too rapidly,
or when following a vehicle too
closely, FCA may not provide a
warning with enough time to help
avoid a crash. It also may not
provide any warning at all. FCA
does not warn of pedestrians,
animals, signs, guardrails, bridges,
construction barrels, or other
objects. Be ready to take action and
apply the brakes. See Defensive
Driving 0185.
FCA can be disabled with the FCA
steering wheel control, or if your
vehicle is equipped with Adaptive
Cruise Control (ACC), through vehicle
