IN CASE OF EMERGENCY325
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or
snow, it can often be moved using a rocking
motion. Turn the steering wheel right and left to
clear the area around the front wheels. Then, shift
back and forth between DRIVE (D) and REVERSE
(R) while gently pressing the accelerator.
NOTE:Shifts between DRIVE (D) and REVERSE (R) can
only be achieved at wheel speeds of 5 mph
(8 km/h) or less. Whenever the transmission
remains in NEUTRAL (N) for more than two
seconds, you must press the brake pedal to
engage DRIVE (D) or REVERSE (R).
Use the least amount of accelerator pedal
pressure that will maintain the rocking motion
without spinning the wheels or racing the engine.
NOTE:Push the ESC OFF button to place the Electronic
Stability Control (ESC) system in “Partial OFF”
mode, before rocking the vehicle Ú page 251.
Once the vehicle has been freed, push the ESC OFF
button again to restore “ESC On” mode.
WARNING!
Fast spinning tires can be dangerous. Forces
generated by excessive wheel speeds may
cause damage, or even failure, of the axle and
tires. A tire could explode and injure someone.
Do not spin your vehicle's wheels faster than
30 mph (48 km/h) or for longer than 30
seconds continuously without stopping when
you are stuck and do not let anyone near a
spinning wheel, no matter what the speed.
CAUTION!
Racing the engine or spinning the wheels may
lead to transmission overheating and failure.
Allow the engine to idle with the transmission
in NEUTRAL for at least one minute after every
five rocking-motion cycles. This will minimize
overheating and reduce the risk of transmis -
sion failure during prolonged efforts to free a
stuck vehicle.
When “rocking” a stuck vehicle by shifting
between DRIVE and REVERSE, do not spin the
wheels faster than 15 mph (24 km/h), or
drivetrain damage may result.
Revving the engine or spinning the wheels too
fast may lead to transmission overheating and
failure. It can also damage the tires. Do not
spin the wheels above 30 mph (48 km/h)
while in gear (no transmission shifting occur -
ring).

IN CASE OF EMERGENCY327
NOTE:
You must ensure that the Auto Park Brake
Úpage 123 feature is disabled before towing
this vehicle to avoid inadvertent Electric Park
Brake engagement. The Auto Park Brake
feature is enabled or disabled via the customer
programmable features in the Uconnect
Settings.
Vehicles with a discharged battery, or total elec -
trical failure when the Electric Park Brake (EPB)
is engaged, will need a wheel dolly or jack to
raise the rear wheels off the ground when
moving the vehicle onto a flatbed.
The Safehold feature will engage the Electric
Park Brake whenever the driver's door is
opened (if the battery is connected, ignition is
ON, transmission is not in PARK, and brake
pedal is released). If you are towing this vehicle
with the ignition in the ON/RUN mode, you must
manually disable the Electric Park Brake each
time the driver's door is opened by pressing the
brake pedal and then releasing the EPB. If you must use the accessories (wipers,
defrosters, etc.) while being towed, the ignition
must be in the ON/RUN mode.
If the vehicle's battery is discharged, instructions
on shifting the automatic transmission out of PARK
(P) in order to move the vehicle Ú
page 323.
REAR-WHEEL DRIVE MODELS
FCA US LLC recommends towing your vehicle with
all four wheels OFF the ground using a flatbed.
If flatbed equipment is not available, and the
transmission is operable, the vehicle may be towed
(with rear wheels off the ground) under the
following conditions:
The transmission must be in NEUTRAL (N). For
instructions on shifting the transmission to
NEUTRAL (N) when the engine is off
Ú page 323.
The towing speed must not exceed 30 mph
(48 km/h).
The towing distance must not exceed 30 miles
(48 km).
CAUTION!
Do not use sling type equipment when towing.
Vehicle damage may occur.
When securing the vehicle to a flat bed truck,
do not attach to front or rear suspension
components. If vehicle is equipped with
Quadra-lift air suspension, secure vehicle only
with tire/wheel straps (no suspension compo -
nents or body) to prevent air suspension from
adjusting during towing against securement
straps and causing damage. Damage to your
vehicle may result from improper towing.
CAUTION!
Towing faster than 30 mph (48 km/h) or
farther than 30 miles (48 km) with rear
wheels on the ground can cause severe trans -
mission damage. Damage from improper
towing is not covered under the New Vehicle
Limited Warranty.

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. This
means that service is required for your vehicle.
Operating conditions such as frequent short-trips,
trailer tow, extremely hot or cold ambient
temperatures, and E85 fuel usage will influence
when the “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.
NOTE:Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km),
12 months 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.
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.
Check the fluid levels of the coolant reservoir,
brake master cylinder and fill as needed.
Check function of all interior and exterior lights.

SERVICING AND MAINTENANCE331
MAINTENANCE PLAN
Refer to the Maintenance Plan for the required maintenance intervals.
At Every Oil Change Interval As Indicated By Oil Change Indicator System:
Change oil and filter.
Rotate the tires at the first sign of irregular wear, even if it occurs before the oil indicator system turns on.
Inspect battery and clean and tighten terminals as required.
Inspect the CV/Universal joints.
Inspect brake pads, shoes, rotors, drums, hoses and parking brake.
Inspect engine cooling system protection and hoses.
Inspect exhaust system.
Inspect engine air cleaner filter if using in dusty or off-road conditions. Replace engine air cleaner filter, as necessary.
