Assist on again, select On in vehicle
personalization. The On with Towbar setting
allows Park Assist to work properly with a
trailer hitch. Some larger trailer hitches may
not be compatible.
Turn off Park Assist when towing a trailer.
To turn the RPA symbols on or off, from the
infotainment screen, touch Settings >
Vehicle > Comfort and Convenience > Rear
Park Assist Symbols.
Rear Cross Traffic Alert (RCTA)
System
If equipped, when the vehicle is shifted into
R (Reverse), RCTA shows a red warning
triangle with a left or right pointing arrow
on the infotainment display 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.
RCTA is disabled when the trailer connection
status is displayed.
RCTA can be turned off. To view available
settings from the infotainment screen, touch
Settings > Vehicle > Collision/Detection
Systems.
Assistance Systems for Driving
If equipped, when driving the vehicle in a
forward gear, Forward Collision Alert (FCA),
Front Pedestrian Braking, (FPB), Lane
Departure Warning (LDW), Side Blind Zone
Alert (SBZA), Lane Change Alert (LCA), and/or
the Automatic Emergency Braking (AEB) 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 ared flashing alert on the windshield and
rapidly beeps or pulses the drivers seat (if
equipped). 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).
{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
0 194.
FCA can be disabled. To view available
settings from the infotainment screen, touch
Settings > Vehicle > Collision/Detection
Systems.

warned of vehicles rapidly approaching this
area up to approximately 70 m (230 ft)
behind the vehicle.
Trailer Side Blind Zone Area (TSBZA)
If equipped, the TSBZA system is a
lane-changing aid that assists drivers with
avoiding crashes that occur with moving
vehicles in the side blind zone, or blind spot
areas. The trailer side blind zone area adds
the blind zone area along the side of a
trailer that the host vehicle is pulling.
When the vehicle is in a forward gear, the
left or right side mirror display will light up
if a moving vehicle is detected in that trailer
blind zone. If the turn signal is activated and
a vehicle is also detected on the same side,
the display will flash as an extra warning
not to change lanes. Since this system is
part of the Lane Change Alert system, read
the entire Lane Change Alert section before
using this feature.
{Warning
TSBZA does not alert the driver to
vehicles outside of the system detection
zones, pedestrians, bicyclists, or animals.
It may not provide alerts when changing(Continued)
Warning (Continued)
lanes under all driving conditions. Failure
to use proper care when changing lanes
may result in injury, death, or vehicle
damage. Before making a lane change,
always check mirrors, glance over your
shoulder, and use the turn signals.
TSBZA Detection Zones
1. SBZA Detection Zone
2. TSBZA Detection Zone
3. LCA Detection Zone
The Side Blind Zone Alert (SBZA) warning
area starts at approximately the middle of
the vehicle and goes back 5 m (16 ft). The
Trailer Side Blind Zone Alert (TSBZA) warning
area starts at approximately 3 m (10 ft) to
the trailing edge of the vehicle and goes
back up to 21 m (69 ft) behind the vehicle.
The maximum trailer length is 18 m (59 ft).
How the System Works
The LCA/TSBZA symbol lights up in the side
mirrors when the system detects a moving
vehicle in the next lane over that is in the
trailer side blind zone. This indicates it may
be unsafe to change lanes. Before making a
lane change, check the SBZA display, check
mirrors, glance over your shoulder, and use
the turn signals.
Left Side Mirror DisplayRight Side Mirror Display
When the vehicle is started, both outside
mirror LCA/TSBZA displays will briefly come
on to indicate the system is operating.
When the vehicle is in a forward gear, the
left- or right-side mirror display will light up
if a moving vehicle is detected in that blind
zone. If the turn signal is activated in the
same direction as a detected vehicle, this
display will flash as an extra warning not to
change lanes.

290 Driving and Operating
Warning (Continued)
.If the trailer brakes are not operating
properly at any time, or if a DIC
message indicates problems with the
trailer connections or trailer brakes,
carefully pull the vehicle over to the
side of the road when traffic
conditions allow.
Trailer Tires
Special Trailer (ST) tires differ from vehicle
tires. Trailer tires are designed with stiff
sidewalls to help prevent sway and to
support heavy loads. These features can
make it difficult to determine if the trailer
tire pressures are low only based on a visual
inspection.
Always check all trailer tire pressures before
each trip when the tires are cool. Low trailer
tire pressure is a leading cause of trailer tire
blow-outs.
If the vehicle is equipped with a trailer tire
pressure monitoring system, see the trailer
tire pressure monitoring system description
and the trailering app.Trailer tires deteriorate over time. The trailer
tire sidewall will show the week and year
the tire was manufactured. Many trailer tire
manufacturers recommend replacing tires
more than six years old.
Overloading is another leading cause of
trailer tire blow-outs. Never load your trailer
with more weight than the tires are
designed to support. The load rating is
located on the trailer tire sidewall.
Always know the maximum speed rating for
the trailer tires before driving. This may be
significantly lower than the vehicle tire
speed rating. The speed rating may be on
the trailer tire sidewall. If the speed rating is
not shown, the default trailer tire speed
rating is 105 km/h (65 mph).
Trailering App
Trailer Lights App
If equipped, the Trailer Lights App is on the
infotainment home screen.

4. The right turn signal light flashes three times.
5. The reverse lights turn on for about two seconds.
6. Steps 2–5 repeat for approximately one minute and 45 seconds, or until the
test deactivates.
Touch Stop to stop the test. The test
automatically ends after one minute and
45 seconds.
The sequence also deactivates when any of
the following occur:
.The vehicle is turned off.
.The transmission is shifted out of P (Park).
.The brake pedal is pressed.
.The turn signal is activated.
.The hazard warning lights are activated.

Tire Pressure and Temperature
If the TTPMS sensor-to-vehicle learn process
was completed, the status view will display
the current tire pressure and temperature of
the trailer tires related to the active Trailer
Profile. If a tire’s pressure is low or high, the
color of the pressure value will be amber.
If a sensor malfunctions, the values are
dashed lines. If the screen displays “Service
Tire Pressure Monitoring System,” the
vehicle needs to be taken to a dealer for
service.
Touch to set up the TTPMS for the Trailer
Profile. See “Trailer Tire Pressure Setup”
