Heated Seats — If Equipped
On some models, the front and rear seats may be equipped
with heaters located in the seat cushions and seat backs.
WARNING!
•Persons who are unable to feel pain to the skin
because of advanced age, chronic illness, diabetes,
spinal cord injury, medication, alcohol use, exhaus-
tion or other physical condition must exercise care
when using the seat heater. It may cause burns even
at low temperatures, especially if used for long
periods of time.
• Do not place anything on the seat or seatback that
insulates against heat, such as a blanket or cushion.
This may cause the seat heater to overheat. Sitting in
a seat that has been overheated could cause serious
burns due to the increased surface temperature of the
seat.
Front Heated Seats
The front heated seats control buttons are located within
the climate or controls screen of the touchscreen. You can choose from HI, LO, or OFF heat settings. The
indicator arrows in touchscreen buttons indicate the level
of heat in use. Two indicator arrows will illuminate for HI,

NOTE:
•It is not necessary to move the temperature settings for
cold or hot vehicles. The system automatically adjusts
the temperature, mode, and blower speed to provide
comfort as quickly as possible.
• The temperature can be displayed in U.S. or Metric units
by selecting the US/Metric customer-programmable fea-
ture. Refer to the “Uconnect Settings” in “Multimedia”
for further information.
To provide you with maximum comfort in the Automatic
mode during cold start-ups, the blower fan will remain on
low until the engine warms up. The blower will increase in
speed and transition into Auto mode.
Manual Operation Override
This system offers a full complement of manual override
features. The AUTO symbol in the front ATC display will
be turned off when the system is being used in the manual
mode.
Operating Tips
NOTE: Refer to the chart at the end of this section for
suggested control settings for various weather conditions.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corrosion
protection and to protect against engine overheating. OAT
coolant (conforming to MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is functioning
properly and the proper amount, type, and concentration
of coolant is used. Use of the Air Recirculation mode
during Winter months is not recommended, because it may
cause window fogging.
Vacation/Storage
Before you store your vehicle, or keep it out of service (i.e.,
vacation) for two weeks or more, run the air conditioning
system at idle for about five minutes, in fresh air with the
blower setting on high. This will ensure adequate system
lubrication to minimize the possibility of compressor dam-
age when the system is started again.

perature when driving in hot weather, up mountain
grades, or when towing a trailer. It should not be
allowed to exceed the upper limits of the normal
operating range.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer for
service if your vehicle overheats. If you decide to look
under the hood yourself, see “Servicing And Mainte-
nance.” Follow the warnings under the Cooling System
Pressure Cap paragraph.
CAUTION!
Driving with a hot engine cooling system could dam-
age your vehicle. If the temperature gauge reads “H,”
pull over and stop the vehicle. Idle the vehicle with the
air conditioner turned off until the pointer drops back
into the normal range. If the pointer remains on the
“H,” turn the engine off immediately and call an
authorized dealer for service.

•If a requested downshift would cause the engine to
over-speed, that shift will not occur.
• The system will ignore attempts to upshift at too low of
a vehicle speed.
• Holding the (-) paddle depressed will downshift the
transmission to the lowest gear possible at the current
speed.
• Transmission shifting will be more noticeable when
AutoStick is enabled.
• The system may revert to automatic shift mode if a fault
or overheat condition is detected.
To disengage AutoStick mode, press and hold the (+) shift
paddle until DorS is once again indicated in the
instrument cluster. Shifting out of SPORT mode will also
disable AutoStick. You can shift in or out of AutoStick
mode at any time without taking your foot off the accel-
erator pedal.WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their grip
and the vehicle could skid, causing a collision or
personal injury.

234 STARTING AND OPERATING

NOTE:
•When you override and push the SET (+)button or SET
(-) buttons, the new Set Speed will be the current speed
of the vehicle.
• When you use the SET (-)button to decelerate, if the
engine’s braking power does not slow the vehicle suffi-
ciently to reach the set speed, the brake system will
automatically slow the vehicle.
• The ACC system decelerates the vehicle to a full stop
when following a target vehicle. If an ACC host vehicle
follows a target vehicle to a standstill, after two seconds
the driver will either have to push the RES (resume)
button, or apply the accelerator pedal to reengage the
ACC to the existing Set Speed.
• The ACC will bring the vehicle to a complete stop while
following a target vehicle and hold the vehicle for two
seconds in the stop position. If the target vehicle does
not start moving within two seconds, the ACC system
will display a message that the system will release the
brakes and that the brakes must be applied manually. An
audible chime will sound when the brakes are released. •
The ACC system maintains set speed when driving up
hill and down hill. However, a slight speed change on
moderate hills is normal. In addition, downshifting may
occur while climbing uphill or descending downhill.
This is normal operation and necessary to maintain set
speed. When driving up hill and down hill, the ACC
system will cancel if the braking temperature exceeds
normal range (overheated).
Setting The Following Distance In ACC
The specified following distance for ACC can be set by
varying the distance setting between four bars (longest),
three bars (long), two bars (medium) and one bar (short).
Using this distance setting and the vehicle speed, ACC
calculates and sets the distance to the vehicle ahead. This
distance setting displays in the instrument cluster display.
