2016 JEEP GRAND CHEROKEE Snow mode

•If the button is continually pushed, the set speed will
continue to decrease until the button is released, then
the new set speed will be established.
Metric Speed (km/h)
• Pushing the SET -button once will result in a 1 km/h
decrease in set speed. Each subsequent tap of the
button results in a decrease of 1 km/h.
• If the button is continually pushed, the set speed will
continue to decrease until the button is released, then
the new set speed will be established.
To Accelerate For Passing
Press the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
Using Electronic Speed Control On Hills
The transmission may downshift on hills to maintain the
vehicle set speed. NOTE:
The Electronic Speed Control system maintains
speed up and down hills. A slight speed change on
moderate hills is normal.
On steep hills, a greater speed loss or gain may occur so
it may be preferable to drive without Electronic Speed
Control.
WARNING!
Electronic Speed Control can be dangerous where the
system cannot maintain a constant speed. Your ve-
hicle could go too fast for the conditions, and you
could lose control and have an accident. Do not use
Electronic Speed Control in heavy traffic or on roads
that are winding, icy, snow-covered or slippery.

Display Warnings And Maintenance
“Wipe Front Radar Sensor In Front Of Vehicle”
Warning
The “ACC/FCW Unavailable Wipe Front Radar Sensor”
warning will display and also a chime will indicate when
conditions temporarily limit system performance.
This most often occurs at times of poor visibility, such as
in snow or heavy rain. The ACC system may also become
temporarily blinded due to obstructions, such as mud,
dirt or ice. In these cases, the DID will display “ACC/
FCW Unavailable Wipe Front Radar Sensor” and the
system will deactivate.
The “ACC/FCW Unavailable Wipe Front Radar Sensor”
message can sometimes be displayed while driving in
highly reflective areas (i.e. tunnels with reflective tiles, or
ice and snow). The ACC system will recover after thevehicle has left these areas. Under rare conditions, when
the radar is not tracking any vehicles or objects in its path
this warning may temporarily occur.
NOTE:
If the “ACC/FCW Unavailable Wipe Front Radar
Sensor” warning is active Normal (Fixed Speed) Cruise
Control is still available. For additional information refer
to “Normal (Fixed Speed) Cruise Control Mode” in this
section.
If weather conditions are not a factor, the driver should
examine the sensor. It may require cleaning or removal of
an obstruction. The sensor is located in the center of the
vehicle behind the lower grille.
To keep the ACC System operating properly, it is impor-
tant to note the following maintenance items:
• Always keep the sensor clean. Carefully wipe the
sensor lens with a soft cloth. Be cautious not to damage
the sensor lens.

NOTE:BI-LEVEL mode is designed under comfort con-
ditions to provide cooler air out of the panel outlets and
warmer air from the floor outlets.
• Floor Mode
Air comes from the floor outlets. A slight
amount of air is directed through the defrost
and side window demister outlets.
• Mix Mode
Air comes from the floor, defrost and side
window demist outlets. This mode works best
in cold or snowy conditions.
12. Climate Control OFF Button
Press and release this button to turn the Climate Control
ON/OFF. 13. Driver Temperature Control Down Button
Provides the driver with independent temperature con-
trol. Push the button on the faceplate for cooler tempera-
ture settings or on the touchscreen, press and slide the
temperature bar towards the blue arrow button on the
touchscreen for cooler temperature settings.
NOTE:
In Sync mode, this button will also automatically
adjust the passenger temperature setting at the same time.
14. Driver Temperature Control Up Button
Provides the driver with independent temperature con-
trol. Push the button on the faceplate for warmer tem-
perature settings or on the touchscreen, press and slide
the temperature bar towards the red arrow button on the
touchscreen for warmer temperature settings.
NOTE:
In Sync mode, this button will also automatically
adjust the passenger temperature setting at the same time.

fresh air and high blower setting. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.
Window Fogging
Interior fogging on the windshield can be quickly re-
moved by turning the mode selector to Defrost. The
Defrost/Floor mode can be used to maintain a clear
windshield and provide sufficient heating. If side win-
dow fogging becomes objectionable, increase blower
speed to improve airflow and clearing of the side win-
dows. Vehicle windows tend to fog on the inside in mild
but rainy or humid weather.
NOTE:
•Recirculate without A/C should not be used for long
periods, as fogging may occur. •
Automatic Temperature Controls (ATC) will automati-
cally adjust the climate control settings to reduce or
eliminate window fogging on the front windshield.
When this occurs, recirculation will be unavailable.Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions such as leaves. Leaves
collected in the air intake may reduce airflow, and if they
enter the plenum, they could plug the water drains. In
winter months, make sure the air intake is clear of ice,
slush, and snow.
A/C Air Filter
The climate control system filters outside air containing
dust, pollen and some odors. Strong odors cannot be totally
filtered out. Refer to “Maintenance Procedures” in “Main-
taining Your Vehicle” for filter replacement instructions.

can use the gear selector (in the MANUAL position), or
the shift paddles, to manually shift the transmission.
Tapping the gear selector forward (-) while in the
MANUAL (M) position, or tapping the (-) shift paddle on
the steering wheel, will downshift the transmission to the
next lower gear. Tapping the lever rearward (+) (or
tapping the (+) shift paddle) will command an upshift.
NOTE:The shift paddles may be disabled (or re-enabled,
as desired) using the Uconnect Personal Settings.
In AutoStick mode, the transmission will shift up or
down when (+/-) is manually selected by the driver
(using the gear selector, or the shift paddles), unless an
engine lugging or overspeed condition would result. It
will remain in the selected gear until another upshift or
downshift is chosen, except as described below.
• The transmission will automatically downshift as the
vehicle slows (to prevent engine lugging) and will
display the current gear. •
The transmission will automatically downshift to first
gear when coming to a stop. After a stop, the driver
should manually upshift (+) the transmission as the
vehicle is accelerated.
• You can start out, from a stop, in first or second gear
(or third gear, in 4LO range, Snow mode, or Sand
mode). Tapping (+) (at a stop) will allow starting in
second gear. Starting out in second gear can be helpful
in snowy or icy conditions.
• 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.

STARTING AND OPERATING 477

When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the 4WD HI
position at a given road speed. Take care not to overspeed
the engine and do not exceed 25 mph (40 km/h).
Proper operation of four-wheel drive vehicles depends
on tires of equal size, type, and circumference on each
wheel. Any difference will adversely affect shifting and
cause damage to the transfer case.
Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.
WARNING!
You or others could be injured or killed if you leave
the vehicle unattended with the transfer case in the
NEUTRAL position without first fully engaging the

WARNING!(Continued)
parking brake. The transfer case NEUTRAL position
disengages both the front and rear drive shafts from
the powertrain and will allow the vehicle to roll,
even if the transmission is in PARK. The parking
brake should always be applied when the driver is
not in the vehicle.
Shift Positions

4WD system mode position, see the information below:

sand, and dry hard pavement.
NOTE:Refer to “Selec-Terrain – If Equipped” in “Start-
ing And Operating” for further information on the vari-
ous positions and their intended usages.
