390 STARTING AND OPERATING
Your vehicle is now in the perpendicular park position.
When the maneuver is complete, the driver will be instructed
to check the vehicle's parking position. If the driver is satis-
fied with the vehicle position, they should shift to PARK. The
"Active ParkSense Complete - Check Parking Position"
message will be momentarily displayed.
Active Park Sense Complete — Check Parking PositionWARNING!
Drivers must be careful when performing parallel or
perpendicular parking maneuvers even when using the
ParkSense Active Park Assist system. Always check
carefully behind and in front of your vehicle, look
behind and in front of you, and be sure to check for
pedestrians, animals, other vehicles, obstructions, and
blind spots before backing up and moving forward. You
are responsible for safety and must continue to pay
attention to your surroundings. Failure to do so can
result in serious injury or death.
CAUTION!
• The ParkSense Active Park Assist system is only a parking aid and it is unable to recognize every obstacle,
including small obstacles. Parking curbs might be
temporarily detected or not detected at all. Obstacles
located above or below the sensors will not be detected
when they are in close proximity.
• The vehicle must be driven slowly when using the ParkSense Active Park Assist system in order to be able
to stop in time when an obstacle is detected. It is recom -
mended that the driver looks over his/her shoulder
when using the ParkSense Active Park Assist system.

STARTING AND OPERATING 421
Tow/Haul Mode
To reduce potential for automatic transmission overheating,
activate TOW/HAUL mode when driving in hilly areas, or
select a lower gear range (using the Electronic Range Select
(ERS) shift control) on more severe grades.
Speed Control — If Equipped
• Do not use on hilly terrain or with heavy loads.
• When using the speed control, if you experience speeddrops greater than 10 mph (16 km/h), disengage until you
can get back to cruising speed.
• Use speed control in flat terrain and with light loads to maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission over -
heating, take the following actions:
City Driving
In city traffic — while stopped, place the transmission in
NEUTRAL, but do not increase engine idle speed. Highway Driving
• Reduce speed
• Temporarily turn off air conditioning
Air Suspension System

To aid in attaching/detaching the trailer from the vehicle, the air
suspension system can be used. Refer to “Air Suspension
System” in “Starting And Operating” for further information.

NOTE:
The vehicle must remain in the engine running position
while attaching a trailer for proper leveling of the air suspen
-
sion system.
SNOWPLOW
NOTE:
Do not use this model vehicle for snowplow applications.
WARNING!
Snowplows and other aftermarket equipment should not
be added to the front end of your vehicle. The airbag
crash sensors may be affected by the change in the front
end structure. The airbags could deploy unexpectedly or
could fail to deploy during a collision resulting in
serious injury or death.

SERVICING AND MAINTENANCE 527

Example: If garage temperature = 68°F (20°C) and the outside
temperature = 32°F (0°C) then the cold tire inflation pressure
should be increased by 3 psi (21 kPa), which equals 1 psi (7 kPa)
for every 12°F (7°C) for this outside temperature condition.

Tire pressure may increase from 2 to 6 psi (13 to 40 kPa)
during operation. DO NOT reduce this normal pressure
build up or your tire pressure will be too low.
Tire Pressures For High Speed Operation
The manufacturer advocates driving at safe speeds and
within posted speed limits. Where speed limits or conditions
are such that the vehicle can be driven at high speeds, main-
taining correct tire inflation pressure is very important.
Increased tire pressure and reduced vehicle loading may be
required for high-speed vehicle operation. Refer to an autho -
rized tire dealer or original equipment vehicle dealer for
recommended safe operating speeds, loading and cold tire
inflation pressures. Radial Ply Tires
Tire Repair
If your tire becomes damaged, it may be repaired if it meets
the following criteria:
• The tire has not been driven on when flat
• The damage is only on the tread section of your tire (side
-
wall damage is not repairable)
• The puncture is no greater than a ¼ of an inch (6 mm)
Consult an authorized tire dealer for tire repairs and addi -
tional information.
Damaged Run Flat tires, or Run Flat tires that have experi -
enced a loss of pressure should be replaced immediately
with another Run Flat tire of identical size and service
description (Load Index and Speed Symbol). Replace the tire
pressure sensor as well as it is not designed to be reused.
WARNING!
High speed driving with your vehicle under maximum
load is dangerous. The added strain on your tires could
cause them to fail. You could have a serious collision. Do
not drive a vehicle loaded to the maximum capacity at
continuous speeds above 75 mph (120 km/h).
WARNING!
Combining radial ply tires with other types of tires on
your vehicle will cause your vehicle to handle poorly.
The instability could cause a collision. Always use radial
ply tires in sets of four. Never combine them with other
types of tires.

528 SERVICING AND MAINTENANCE
Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive 50 miles
(80 km) at 50 mph (80 km/h) after a rapid loss of inflation
pressure. This rapid loss of inflation is referred to as the Run
Flat mode. A Run Flat mode occurs when the tire inflation
pressure is of/or below 14 psi (96 kPa). Once a Run Flat tire
reaches the run flat mode it has limited driving capabilities
and needs to be replaced immediately. A Run Flat tire is not
repairable. When a run flat tire is changed after driving with
underinflated tire condition, please replace the TPM sensor
as it is not designed to be reused when driven under run flat
mode 14 psi (96 kPa) condition.
NOTE:
TPM Sensor must be replaced after driving the vehicle on a
flat tire condition.
It is not recommended driving a vehicle loaded at full
capacity or to tow a trailer while a tire is in the run flat mode.
See the tire pressure monitoring section for more informa-
tion. Tire Spinning
When stuck in mud, sand, snow, or ice conditions, do not
spin your vehicle's wheels above 30 mph (48 km/h) or for
longer than 30 seconds continuously without stopping.
Refer to “Freeing A Stuck Vehicle” in “In Case Of Emer
-
gency” for further information.
WARNING!
Fast spinning tires can be dangerous. Forces generated
by excessive wheel speeds may cause tire damage or
failure. A tire could explode and injure someone. Do not
spin your vehicle's wheels faster than 30 mph (48 km/h)
for more than 30 seconds continuously when you are
stuck, and do not let anyone near a spinning wheel, no
matter what the speed.

After pressing Next, the Target Pressure screen appears. The default for this option is 50 PSI (344 kPa), however the range is
selectable anywhere between 25–125 PSI (172–862 kPa). Once PSI (kPa) is programmed the pairing screen appears. Tire
sensors must be paired in order shown. Starting with Tire 1, deflate tire by 5 PSI (34 kPa) and wait for a horn chirp. Repeat
process until complete. Do not exit the pairing screen until process is complete. If pairing has been unsuccessful, a double
horn chirp will sound, and a prompt on the touchscreen will allow you to retry the procedure “Retry” will only appear when
setup fails. Each tire must be successfully paired during a single pairing process to receive the success screen. Trailer Name List of Trailer Names
NOTE:
You can select and personalize your trailer name depending on the type of trailer you are hauling. Select the trailer name
