Mist
Push the lever upward to the MIST position and
release for a single wiping cycle.
NOTE:The mist feature does not activate the washer
pump; therefore, no washer fluid will be sprayed on
the windshield. The wash function must be used in
order to spray the windshield with washer fluid.
For information on wiper care and replacement,
see Ú page 275.
RAIN SENSING WIPERS — IF EQUIPPED
This feature senses rain or snow fall on the
windshield and automatically activates the wipers.
Rotate the end of the multifunction lever to one of
two detent positions to activate this feature.
The sensitivity of the system can be adjusted with
the multifunction lever. Wiper delay position one is
the least sensitive, and wiper delay position two is
the most sensitive. Place the wiper switch in the
O (off) position when not using the system.
NOTE:
The Rain Sensing feature will not operate when
the wiper switch is in the low or high-speed posi -
tion.
The Rain Sensing feature may not function prop -
erly when ice, or dried salt water is present on
the windshield.
Use of Rain-X or products containing wax or sili-
cone may reduce Rain Sensing performance.
The Rain Sensing feature can be turned on and
off through Uconnect Settings Ú page 165.
The Rain Sensing system has protection features
for the wiper blades and arms, and will not operate
under the following conditions:
Change In Ignition Position — If the vehicle is in
Rain Sensing mode and the ignition is cycled
from OFF to ON, the auto wiper will be
suppressed until vehicle speed is greater than
3 mph (5 km/h), or the wiper switch is moved
out of and back into the Intermittent wipe posi -
tion.
Transmission In NEUTRAL Position — The Rain
Sensing system will not operate if the NEUTRAL
gear is selected at speeds of 3 mph (5 km/h) or
less unless the wiper switch is moved or the
gear selector is moved out of NEUTRAL.
Remote Start Mode Inhibit — On vehicles
equipped with the Remote Start system, Rain
Sensing wipers are not operational when the
vehicle is in Remote Start mode. Once the oper -
ator is in the vehicle and has placed the ignition
switch in the ON/RUN position, Rain Sensing
wiper operation can resume, if it has been
selected, and no other inhibit conditions
(mentioned previously) exist.
REAR WINDOW WIPER/WASHER
The rear wiper/washer controls are located on the
windshield wiper/washer lever on the right side of
the steering column. The rear wiper/washer is
operated by rotating a switch, located at the
middle of the lever.
The rear wiper/washer controls are located on the
windshield wiper/washer lever on the right side of
the steering column. The rear wiper has different
operation modes:
Intermittent mode
Synchronous mode (at half speed of the front
window wiper) when the front window wiper is
operating
Continuous mode
Vehicle in REVERSE: If the front wiper is active
and the REVERSE gear is selected, the wiper will
turn on for one wipe
Rotate the center portion of the lever
upward to the first detent for intermittent
operation and to the second detent for
continuous rear wiper operation.
To use the washer, push the lever
forward and hold while spray is desired.

Brake Warning Light
This warning light monitors various brake
functions, including brake fluid level and
parking brake application. If the brake
light turns on it may indicate that the
parking brake is applied, that the brake fluid level
is low, or that there is a problem with the Anti-Lock
Brake System reservoir.
If the light remains on when the parking brake has
been disengaged, and the fluid level is at the full
mark on the master cylinder reservoir, it indicates
a possible brake hydraulic system malfunction or
that a problem with the Brake Booster has been
detected by the Anti-Lock Brake System (ABS) /
Electronic Stability Control (ESC) system. In this
case, the light will remain on until the condition has
been corrected. If the problem is related to the
brake booster, the ABS pump will run when
applying the brake, and a brake pedal pulsation
may be felt during each stop.
The dual brake system provides a reserve braking
capacity in the event of a failure to a portion of the
hydraulic system. A leak in either half of the dual
brake system is indicated by the Brake Warning
Light, which will turn on when the brake fluid level
in the master cylinder has dropped below a
specified level.
The light will remain on until the cause is corrected.
NOTE:The light may flash momentarily during sharp
cornering maneuvers, which change fluid level
conditions. The vehicle should have service
performed, and the brake fluid level checked.
If brake failure is indicated, immediate repair is
necessary.
Vehicles equipped with the Anti-Lock Brake System
(ABS) are also equipped with Electronic Brake
Force Distribution (EBD). In the event of an EBD
failure, the Brake Warning Light will turn on along
with the ABS Light. Immediate repair to the ABS
system is required.
Operation of the Brake Warning Light can be
checked by turning the ignition switch from the OFF
position to the ON/RUN position. The light should
illuminate for approximately two seconds. The light
should then turn off unless the parking brake is
applied or a brake fault is detected. If the light does
not illuminate, have the light inspected by an
authorized dealer. The light also will turn on when the parking brake
is applied with the ignition switch in the ON/RUN
position.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake appli
-
cation.
Battery Charge Warning Light
This warning light will illuminate when the
battery is not charging properly. If it stays
on while the engine is running, there may
be a malfunction with the charging
system. Contact an authorized dealer as soon
as possible.
This indicates a possible problem with the
electrical system or a related component.
Door Open Warning Light
This indicator will illuminate when a door
is ajar/open and not fully closed.
NOTE:If the vehicle is moving, there will also be a single
chime.
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have
failed. It will take longer to stop the vehicle. You
could have a collision. Have the vehicle checked
immediately.

162STARTING AND OPERATING
Flowing Water
If the water is swift flowing and rising (as in storm
run-off) avoid crossing until the water level recedes
and/or the flow rate is reduced. If you must cross
flowing-water, avoid depths in excess of 9 inches
(22 cm). The flowing water can erode the
streambed causing your vehicle to sink into deeper
water. Determine exit point(s) that are downstream
of your entry point to allow for drifting.
Standing Water
Avoid driving in standing water deeper than
16 inches (40.5 cm), and reduce speed
appropriately to minimize wave effects. Maximum
speed in 16 inches (40.5 cm) of water is less than
5 mph (8 km/h).
(Trailhawk only): Avoid driving in standing water
deeper than 19 inches (48 cm), and reduce speed
appropriately to minimize wave effects. Maximum
speed in 19 inches (48 cm) of water is less than
5 mph (8 km/h).
Maintenance
After driving through deep water, inspect your
vehicle fluids and lubricants (engine, transmission,
Power Transfer Unit, and Rear Drive Module) to
ensure they have not been contaminated.
Contaminated fluids and lubricants (milky, foamy
in appearance) should be flushed/changed as
soon as possible to prevent component damage.
Driving In Snow, Mud And Sand
In heavy snow, when pulling a load, or for
additional control at slower speeds, shift the
transmission to a low gear and shift the 4WD
system to the appropriate terrain mode, using
4WD LOW if necessary Úpage 112. Do not shift to
a lower gear than necessary to maintain headway.
Over-revving the engine can spin the wheels and
traction will be lost.
Avoid abrupt downshifts on icy or slippery roads
because engine braking may cause skidding and
loss of control.
Hill Climbing
NOTE:Before attempting to climb a hill, determine the
conditions at the crest and/or on the other side.
Before climbing a steep hill, shift the transmission
to a lower gear and shift the 4WD System to 4WD
LOW. Use FIRST gear and 4WD LOW for very steep
hills.
NOTE:Brakes should be applied at increased slippage,
but before coming to a stop to avoid digging into
the loose surface and rendering the operator of the
vehicle stuck/immobile. If you stall or begin to lose headway
while climbing
a steep hill, allow your vehicle to come to a stop
and immediately apply the brakes. Once stopped,
shift to REVERSE. Back slowly down the hill
allowing the compression braking of the engine to
help regulate your speed. If the brakes are
required to control vehicle speed, apply them
lightly and avoid locking or skidding the tires.
NOTE:Remember, never drive diagonally across a hill -
drive straight up or down.
If the wheels start to slip as you approach the crest
of a hill, ease off the accelerator and maintain
headway by turning the front wheels slowly left and
right. This may provide a fresh “bite” into the
surface and may provide traction to complete the
climb.
WARNING!
If the engine stalls or you lose headway or
cannot make it to the top of a steep hill or grade,
never attempt to turn around. To do so may
result in tipping and rolling the vehicle. Always
back straight down a hill in REVERSE gear
carefully. Never back down a hill in NEUTRAL
using only the brake.

242SAFETY
(Continued)
PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE OUTSIDE THE VEHICLE
Tires
Examine tires for excessive tread wear and uneven
wear patterns. Check for stones, nails, glass, or
other objects lodged in the tread or sidewall.
Inspect the tread for cuts and cracks. Inspect
sidewalls for cuts, cracks, and bulges. Check the
lug nut/bolt torque for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel or
brake fluid leaks are suspected, the cause should
be located and corrected immediately.
ONLY use the driver’s side floor mat on the
driver’s side floor area. To check for interfer -
ence, with the vehicle properly parked with the
engine off, fully depress the accelerator, the
brake, and the clutch pedal (if present) to
check for interference. If your floor mat inter -
feres with the operation of any pedal, or is not
secure to the floor, remove the floor mat from
the vehicle and place the floor mat in your
trunk.
ONLY use the passenger’s side floor mat on
the passenger’s side floor area.
ALWAYS make sure objects cannot fall or slide
into the driver’s side floor area when the
vehicle is moving. Objects can become
trapped under accelerator, brake, or clutch
pedals and could cause a loss of vehicle
control.
WARNING!
NEVER place any objects under the floor mat
(e.g., towels, keys, etc.). These objects could
change the position of the floor mat and may
cause interference with the accelerator,
brake, or clutch pedals.
If the vehicle carpet has been removed and
re-installed, always properly attach carpet to
the floor and check the floor mat fasteners are
secure to the vehicle carpet. Fully depress
each pedal to check for interference with the
accelerator, brake, or clutch pedals then
re-install the floor mats.
It is recommended to only use mild soap and
water to clean your floor mats. After cleaning,
always check your floor mat has been properly
installed and is secured to your vehicle using
the floor mat fasteners by lightly pulling mat.
WARNING!

SERVICING AND MAINTENANCE
SCHEDULED SERVICING
Your vehicle is equipped with an automatic oil
change indicator system. The oil change indicator
system will remind you that it is time to take your
vehicle in for scheduled maintenance.
Based on engine operation conditions, the oil
change indicator message will illuminate in the
instrument cluster. This means that service is
required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow and
extremely hot or cold ambient temperatures will
influence when the “Change Oil” or “Oil Change
Required” message is displayed. Have your vehicle
serviced as soon as possible, within the next
500 miles (805 km).An authorized dealer will reset the oil change
indicator message after completing the scheduled
oil change. If a scheduled oil change is performed
by someone other than an authorized dealer, the
message can be reset by referring to the steps
described under Instrument Cluster Display
Ú
page 77.
NOTE:Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km), one
year or 350 hours of engine run time, whichever
comes first. The 350 hours of engine run or idle
time is generally only a concern for fleet
customers.
NOTE:The Oil Change Indicator will not illuminate under
these conditions. Once A Month Or Before A Long Trip:
Check engine oil level.
Check windshield washer fluid level.
Check the tire inflation pressures and look for
unusual wear or damage. Rotate tires at the first
sign of irregular wear, even if it occurs before
the oil indicator system turns on.
Check the fluid levels of the coolant reservoir,
and brake master cylinder reservoir, and fill as
needed.
Check function of all interior and exterior lights.

282SERVICING AND MAINTENANCE
(Continued)
Do not overfill the coolant expansion bottle.
Check the coolant freeze point in the radiator
and in the coolant expansion bottle. If engine
coolant needs to be added, the contents of the
coolant expansion bottle must also be protected
against freezing.
If frequent engine coolant additions are
required, the cooling system should be pressure
tested for leaks.
Maintain engine coolant concentration at a
minimum of 50% OAT coolant (conforming to
MS.90032) and distilled water for proper corro-
sion protection of your engine which contains
aluminum components.
Make sure that the coolant expansion bottle
overflow hoses are not kinked or obstructed.
Keep the front of the radiator clean. If your
vehicle is equipped with air conditioning, keep
the front of the condenser clean.
Do not change the thermostat for Summer or
Winter operation. If replacement is ever neces -
sary, install ONLY the correct type thermostat.
Other designs may result in unsatisfactory
engine cooling performance, poor gas mileage,
and increased emissions.
BRAKE SYSTEM
In order to ensure brake system performance, all
brake system components should be inspected
periodically. For the proper maintenance intervals
Ú page 268.
Brake Master Cylinder
The fluid in the master cylinder should be checked
when performing under hood services or
immediately if the Brake Warning Light is
illuminated.
Be sure to clean the top of the master cylinder area
before removing the cap. If necessary, add fluid to
bring the fluid level up to the requirements
described on the brake fluid reservoir. With disc
brakes, fluid level can be expected to fall as the
brake pads wear. Brake fluid level should be
checked when pads are replaced. However, low
fluid level may be caused by a leak and a checkup
may be needed. Use only the manufacturer recommended brake
fluid Ú
page 324.
WARNING!

Riding the brakes can lead to brake failure and
possibly a collision. Driving with your foot resting or
riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear,
and possible brake damage. You would not have
your full braking capacity in an emergency.

WARNING!
Use only the manufacturer recommended
brake fluid Úpage 324. Using the wrong type
of brake fluid can severely damage your brake
system and/or impair its performance. The
proper type of brake fluid for your vehicle is
also identified on the original factory installed
hydraulic master cylinder reservoir.
To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that
has been in a tightly closed container. Keep
the master cylinder reservoir cap secured at
all times. Brake fluid in a open container
absorbs moisture from the air resulting in a
lower boiling point. This may cause it to boil
unexpectedly during hard or prolonged
braking, resulting in sudden brake failure.
This could result in a collision.
Overfilling the brake fluid reservoir can result
in spilling brake fluid on hot engine parts,
causing the brake fluid to catch fire. Brake
fluid can also damage painted and vinyl
surfaces, care should be taken to avoid its
contact with these surfaces.

AUTOMATIC TRANSMISSION —
I
F EQUIPPED
Special Additives
It is strongly recommended against using any
special additives in the transmission. Automatic
Transmission Fluid (ATF) is an engineered product
and its performance may be impaired by
supplemental additives. Therefore, do not add any
fluid additives to the transmission. The only
exception to this policy is the use of special dyes
for diagnosing fluid leaks in 6-speed
transmissions. Avoid using transmission sealers as
they may adversely affect seals.
Fluid Level Check
The fluid level is preset at the factory and does not
require adjustment under normal operating
conditions. Routine fluid level checks are not
required; therefore the transmission has no
dipstick. An authorized dealer can check your
transmission fluid level using special service tools.
If you notice fluid leakage or transmission
malfunction, visit an authorized dealer
immediately to have the transmission fluid level
checked. Operating the vehicle with an improper
fluid level can cause severe transmission damage.
Fluid And Filter Changes
Under normal operating conditions, the fluid
installed at the factory will provide satisfactory
lubrication for the life of the vehicle.
Routine fluid and filter changes are not required.
However, change the fluid and filter if the fluid
becomes contaminated (with water, etc.), or if the
transmission is disassembled for any reason.
Selection Of Lubricant
It is important to use the proper transmission fluid
to ensure optimum transmission performance and
life. Use only the manufacturer specified
transmission fluid Ú page 324. It is important to
maintain the transmission fluid at the correct level
using the recommended fluid.
NOTE:No chemical flushes should be used in any trans -
mission; only the approved lubricant should be
used.
Do not allow petroleum-based fluid to contam -
inate the brake fluid. Brake seal components
could be damaged, causing partial or
complete brake failure. This could result in a
collision.
CAUTION!
Do not use chemical flushes in your
transmission as the chemicals can damage your
transmission components. Such damage is not
covered by the New Vehicle Limited Warranty.
WARNING!
CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe
transmission damage may occur. An authorized
dealer has the proper tools to adjust the fluid
level accurately.
CAUTION!
Using a transmission fluid other than the
manufacturer recommended fluid may cause
deterioration in transmission shift quality and/or
torque converter shudder. For fluid
specifications Ú page 324.
