How the System Works
The instrument cluster may
have a Park Assist display with
bars that show“distance to
object,” driving direction, and
object location information for
the Park Assist system. As the
object gets closer, more bars
light up and the bars change
color from yellow to amber
to red.
Beeps sound to warn the
driver of certain objects that
are detected around the
vehicle. The frequency of
beeps increases as the vehicle
gets closer to the object.
When the object is very close
to the vehicle, the beeps are
continuous. Beeps for the
front are higher pitched than
beeps for the rear. If equipped
with Safety Alert seat, both
sides of the seat will pulse
alongside the beeps. When the System Does Not
Seem to Work Properly
The following messages may
be displayed on the DIC:
SERVICE PARKING ASSIST :
If this message occurs, check
the following conditions:
.The sensors are not clean.
Keep the vehicle's rear
bumper free of mud, dirt,
snow, ice, and slush. For
cleaning instructions, see

.The Park Assist sensors are
covered by frost or ice.
Frost or ice can form around
and behind the sensors and
may not always be seen; this
can occur after washing the
vehicle in cold weather. The
message may not clear until
the frost or ice has melted.
If the above conditions do not
exist, take the vehicle to your
dealer to repair the system. PARK ASSIST OFF :
If the PA
system does not activate due
to a temporary condition, the
appropriate message displays
on the DIC. PA OFF message
is displayed when disabled by

Trailer Towing
General Towing
Information
Only use towing equipment
that has been designed for the
vehicle. Contact your dealer or
trailering dealer for assistance
with preparing the vehicle to
tow a trailer. Read the entire
section before towing a trailer.
To tow a disabled vehicle, see
Transporting a Disabled
Vehicle (Electronic Shifter)
0450 or
Transporting a Disabled
Vehicle (Mechanical Shifter)
0 452. To tow the vehicle
behind another vehicle such as
a motor home, see
Recreational Vehicle Towing
0 454.
When towing with the 2.0L L4
engine, only use unleaded
gasoline with an octane rating
of 89 or higher. Using gasoline
with a lower octane rating while towing may damage the
engine and may not be
covered by the vehicle
warranty. See Recommended
Fuel (LSY 2.0L L4 Turbo
Engine)
0354 or
Recommended Fuel (L3B 2.7L
L4 Turbo and LF4 3.6L V6
Twin Turbo Engines) 0355.
Driving
Characteristics and
Towing Tips
{Warning
You can lose control when
towing a trailer if the correct
equipment is not used or the
vehicle is not driven
properly. For example, if the
trailer is too heavy or the
trailer brakes are
inadequate for the load, the

360 Driving and Operating
If equipped, the following
driver assistance features
should be turned to alert or
off when towing a trailer:
.Automatic Emergency
Braking (AEB)
.Intelligent Brake Assist (IBA)
.Front Pedestrian
Braking (FPB)
If equipped with Lane Change
Alert (LCA), the LCA detection
zones that extend back from
the side of the vehicle do not
move further back when a
trailer is towed. Use caution
while changing lanes when
towing a trailer.
If equipped with Rear Cross
Traffic Alert (RCTA), 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.
{Warning
To prevent serious injury or
death from carbon monoxide
(CO), when towing a trailer:
.Do not drive with the
liftgate, trunk/hatch,
or rear-most
window open.
.Fully open the air outlets
on or under the
instrument panel.
.Adjust the climate control
system to a setting that
brings in only outside air.
See “Climate Control
Systems” in the Index.
For more information about
carbon monoxide, see
Engine Exhaust 0271.
Towing a trailer requires
experience. The combination
of the vehicle and trailer is
longer and not as responsive
as the vehicle itself. Become
familiar with handling and braking by driving on a level
road surface before driving on
public roads.
The trailer structure, the tires,
and the brakes must be all be
rated to carry the intended
cargo. Inadequate trailer
equipment can cause the
combination to operate in an
unexpected or unsafe manner.
Before driving, inspect all
trailer hitch parts and
attachments, safety chains,
electrical connectors, lamps,
tires, and mirrors. See Towing
Equipment
0365. If the trailer
has electric brakes, start the
combination moving and then
manually apply the trailer
brake controller to check the
trailer brakes work. During the
trip, occasionally check that
the cargo and trailer are
secure and that the lamps and
any trailer brakes are working.
