within a zone 25 cm (10 in) high off
the ground and below bumper level.
These detection distances may be
shorter during warmer or humid
weather. Blocked sensors will not
detect objects and can also cause
false detections. Keep the sensors
clean of mud, dirt, snow, ice, and
slush; and clean sensors after a car
wash in freezing temperatures.
{Warning
The parking assist system does
not detect children, pedestrians,
bicyclists, animals, or objects
located below the bumper or that
are too close or too far from the
vehicle. It is not available at
speeds greater than 8 km/h
(5 mph). To prevent injury, death,
or vehicle damage, even with
parking assist, always check the
area around the vehicle and
check all mirrors before moving
forward or backing.
The instrument cluster may have a
parking assist display with bars that
show“distance to object” and object
location information for the Parking
Assist system. As the object gets
closer, more bars light up and the
bars change color from yellow to
amber to red.
When an object is first detected in
the rear, one beep will be heard
from the rear, or both sides of the
Safety Alert Seat will pulse two
times. When an object is very close
(<0.6 m (2 ft) in the vehicle rear,
or <0.3 m (1 ft) in the vehicle front),
five beeps will sound from the front
or rear depending on object
location, or both sides of the Safety
Alert Seat will pulse five times. Beeps for Front Parking Assist are
higher pitched than for Rear Parking
Assist.
Backing Warning and Rear
Automatic Braking
Vehicles with Adaptive Cruise
Control (ACC) have the (RAB)
system. The Backing Warning part
of this system can warn of rear
objects when backing up at speeds
greater than 8 km/h (5 mph).
The Backing Warning System will
beep once from the rear when a
potential object threat is first
detected, or pulse twice on both
sides of the Safety Alert Seat. When
the system detects a potential
imminent crash, beeps will be heard
from the rear, or five pulses will be
felt on both sides of the Safety Alert
Seat. There may also be a brief,
sharp application of the brakes.

9-52 Driving and Operating
{Warning
The Backing Warning System
only operates at speeds greater
than 8 km/h (5 mph). It does not
detect children, pedestrians,
bicyclists, animals, or objects
below the bumper or that are too
close or too far from the vehicle.
In some situations, such as at
higher backing speeds, there may
not be enough time for the short,
sharp application of the vehicle
brake system to occur. To prevent
injury, death, or vehicle damage,
even with the Backing Warning
System, always check the area
around the vehicle and check all
mirrors before backing.
When the vehicle is in R (Reverse)
and if it is backing too fast to avoid
a crash with a detected object
directly behind the vehicle, the Rear
Automatic Braking (RAB) system may automatically brake hard to a
stop to help avoid or reduce the
harm caused by a backing crash.
{Warning
Rear Automatic Braking may not
avoid many types of backing
crashes. Do not wait for the
automatic braking to apply. This
system is not designed to replace
driver braking and only works in
R (Reverse) when an object is
detected directly behind the
vehicle. It may not brake or stop
in time to avoid a crash. It will not
brake for objects when the
vehicle is moving at very low
speeds. It does not detect
children, pedestrians, bicyclists,
animals, or objects below the
bumper or that are too close or
too far from the vehicle. To
prevent injury, death, or vehicle
damage, even with Rear
(Continued)
Warning (Continued)
Automatic Braking, always check
the area around the vehicle
before and while backing.
Pressing the brake pedal after the
vehicle comes to a stop will release
the Rear Automatic Braking. If the
brake pedal is not pressed soon
after the stop, the Electric Parking
Brake (EPB) may be set. When it is
safe, press the accelerator pedal
firmly at any time to override the
Rear Automatic Braking.
{Warning
There may be instances where
unexpected or undesired
automatic braking occurs. If this
happens, either press the brake
pedal or firmly press the
accelerator pedal to release the
brakes from the Rear Automatic (Continued)

Warning (Continued)
Braking system. Before releasing
the brakes, check the RVC
screen and check the area
around the vehicle to make sure it
is safe to proceed.
Rear Cross Traffic Alert (RCTA)
If equipped, RCTA displays a red
warning triangle with a left or right
pointing arrow on the RVC screen to
warn of traffic coming from the left
or right. This system detects objects
coming from up to 20 m (65 ft) from
the left or right side of the vehicle.
When an object is detected, either
three beeps sound from the left or
right or three Safety Alert Seat
pulses occur on the left or right side,
depending on the direction of the
detected vehicle.
Use caution while backing up when
towing a trailer, as the RCTA
detection zones that extend out from the back of the vehicle do not
move further back when a trailer is
towed.
Turning the Features On or Off
TheXbutton to the left of the
steering wheel is used to turn on or
off the Front and Rear Parking
Assist, Rear Cross Traffic Alert
(RCTA), Rear Automatic Braking,
and Backing Warning System at the
same time. The indicator light next
to the button comes on when the
features are on and turns off when
the features have been disabled.
Turn off parking assist and Rear
Automatic Braking when towing a
trailer. The parking assist symbols or
guidance lines can be turned on or
off through the Settings menu on
the infotainment system:
1. On the infotainment system,
press the Settings screen
button, or turn the MENU knob
to highlight Settings and
press MENU.
2. Select Rear Camera.
3. Press Park Assist Symbols or Guidance Lines and then select

Automatic Collision
Preparation (ACP) System
When driving in a forward gear
above 4 km/h (2.5 mph), ACP may
help reduce crash damage by
applying the brakes. It has a
detection range of approximately
60 m (197 ft). This front automatic
braking can only occur if a vehicle is
detected. This is shown by the FCA
vehicle ahead indicator being lit.
SeeForward Collision Alert (FCA)
System on page 9-54.
{Warning
ACP is an emergency crash
preparation feature and is not
designed to avoid crashes. Do
not rely on ACP to brake the
vehicle.
ACP may not:
.Respond to stopped vehicles,
pedestrians, or animals.
(Continued)
Warning (Continued)
.Detect a vehicle ahead on
winding or hilly roads.
.Detect a stopped or
slow-moving vehicle or other
object ahead.
.Detect a vehicle when
weather limits visibility, such
as in fog, rain, or snow. In
these situations, ACP sensor
performance is limited.
Complete attention is always
required while driving, and you
should be ready to take action
and apply the brakes and/or steer
the vehicle to avoid crashes.
Brake Preparation
When quickly approaching a vehicle
ahead, Brake Preparation reduces
brake response time by having the
brake system prepared for driver
braking to occur more rapidly. Automatic Braking
If ACP detects it is about to crash
with the vehicle you are following
that is moving or has come to a
stop, and the brakes have not been
applied, it may automatically brake
hard. This can help to reduce crash
damage and it may even help to
avoid some very low speed crashes.
Automatic Braking may slow the
vehicle to a complete stop to try to
avoid a potential crash. If this
happens, Automatic Braking may
engage the Electric Parking Brake
(EPB) to hold the vehicle at a stop.
To release the EPB, press the EPB
button. A firm press of the
accelerator pedal will also release
Automatic Braking and the EPB.
{Warning
Automatic Braking may
automatically brake the vehicle
suddenly in situations where it is
unexpected and undesired.

9-70 Driving and Operating
Caution (Continued)
The vehicle could be damaged.
Avoid making very sharp turns
while trailering.
When turning with a trailer, make
wider turns than normal. Do this so
the trailer will not strike soft
shoulders, curbs, road signs, trees,
or other objects. Avoid jerky or
sudden maneuvers. Signal well in
advance.
If the trailer turn signal bulbs burn
out, the arrows on the instrument
cluster will still flash for turns. It is
important to check occasionally to
be sure the trailer bulbs are still
working.
Driving on Grades
Reduce speed and shift to a lower
gear before starting down a long or
steep downgrade. If the
transmission is not shifted down, the
brakes might get hot and no longer
work well. Vehicles can tow in D (Drive). Shift
the transmission to a lower gear if
the transmission shifts too often
under heavy loads and/or hilly
conditions.
When towing at high altitude on
steep uphill grades, consider the
following: Engine coolant will boil at
a lower temperature than at normal
altitudes. If the engine is turned off
immediately after towing at high
altitude on steep uphill grades, the
vehicle may show signs similar to
engine overheating. To avoid this,
let the engine run while parked,
preferably on level ground, with the
automatic transmission in P (Park)
for a few minutes before turning the
engine off. If the overheat warning
comes on, see
Engine Overheating
on page 10-20.
Parking on Hills
{Warning
Parking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both
the vehicle and the trailer can be
damaged. When possible, always
park the rig on a flat surface.
If parking the rig on a hill:
1. Press the brake pedal, but do not shift into P (Park) yet. Turn
the wheels into the curb if facing
downhill or into traffic if facing
uphill.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the regular brakes
until the chocks absorb the load.

4. Reapply the brake pedal. Thenapply the parking brake and shift
into P (Park).
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal.
2. Start the engine.
3. Shift into a gear.
4. Release the parking brake.
5. Let up on the brake pedal.
6. Drive slowly until the trailer is clear of the chocks.
7. Stop and have someone pick up and store the chocks.
Maintenance when Trailer
Towing
The vehicle needs service more
often when pulling a trailer. See
Maintenance Schedule on
page 11-3. Things that are
especially important in trailer
operation are automatic
transmission fluid, engine oil, axle lubricant, belts, cooling system, and
brake system. It is a good idea to
inspect these before and during
the trip.
Check periodically to see that all
hitch nuts and bolts are tight.
Trailer Towing (Sedan
With V6 Engine)
Before pulling a trailer, three
important considerations have to do
with weight:
.Weight of the trailer.
.Weight of the trailer tongue.
.Total weight on your vehicle's
tires.
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than
454 kg (1,000 lb). But even that can
be too heavy.
It depends on how the rig is used.
For example, speed, altitude, road
grades, outside temperature, andhow much the vehicle is used to pull
a trailer are all important. It can
depend on any special equipment
on the vehicle, and the amount of
tongue weight the vehicle can carry.
See
“Weight of the Trailer Tongue”
later in this section.
Maximum trailer weight is calculated
assuming only the driver is in the
tow vehicle and it has all the
required trailering equipment. The
weight of additional optional
equipment, passengers, and cargo
in the tow vehicle must be
subtracted from the maximum trailer
weight.
Ask your dealer for trailering
information or advice, or write us at
our Customer Assistance Offices.
See Customer Assistance Offices
on page 13-3.
Weight of the Trailer Tongue
The tongue load (1) of any trailer is
an important weight to measure
because it affects the total gross
weight of the vehicle. The Gross
Vehicle Weight (GVW) includes the

1. Before starting this check, besure there is enough room
around the vehicle.
2. Apply both the parking brake and the regular brake.
Do not use the accelerator
pedal, and be ready to turn off
the engine immediately if it
starts.
3. For automatic transmission vehicles, try to start the engine
in each gear. The vehicle should
start only in P (Park) or
N (Neutral). If the vehicle starts
in any other position, contact
your dealer for service.
For manual transmission
vehicles, put the shift lever in
Neutral, push the clutch pedal
down halfway, and try to start
the engine. The vehicle should
start only when the clutch pedal
is pushed down all the way to
the floor. If the vehicle starts
when the clutch pedal is not
pushed all the way down,
contact your dealer for service.Automatic Transmission

pedal. Do this until the vehicle is
held by the parking brake only.
.To check the P (Park)
mechanism's holding ability:
With the engine running, shift to
P (Park). Then release the
parking brake followed by the
regular brake.
Contact your dealer if service is
required.
Wiper Blade Replacement
Windshield wiper blades should be
inspected for wear and cracking.
See Maintenance Schedule on
page 11-3.
Replacement blades come in
different types and are removed in
different ways. For proper type and
length, see Maintenance
Replacement Parts on page 11-15. To replace the windshield wiper
blade:
1. Pull the windshield wiper
assembly away from the
windshield.
2. Lift up on the latch in the middleof the wiper blade where the
wiper arm attaches.
3. With the latch open, pull the wiper blade down toward the
windshield far enough to release
it from the J-hooked end of the
wiper arm. 4. Remove the wiper blade.
Allowing the wiper blade arm to
touch the windshield when no
wiper blade is installed could
damage the windshield. Any
damage that occurs would not
be covered by the vehicle
warranty. Do not allow the wiper
blade arm to touch the
windshield.
5. Reverse Steps 1–3 for wiper blade replacement.
Windshield Replacement
The windshield is part of the HUD
system. If the vehicle has to have
the windshield replaced, get one
that is designed for HUD or the
HUD image may look out of focus.
