IN CASE OF EMERGENCY349
To Reset The Manual Park Release:

1. Push the locking tab to the right, to unlock
the lever.

2. Rotate the Manual Park Release lever forward to its original position, until the
locking tab snaps into place to secure the
lever.
3. Pull gently on the tether strap to confirm that the lever is locked in its stowed
position.
4. Re-install the access cover.
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. Use the
least amount of accelerator pedal pressure that
will maintain the rocking motion, without
spinning the wheels or racing the engine.
NOTE:
For trucks equipped with an 8–speed trans
-
mission, shifts between DRIVE and REVERSE
can only be achieved at wheel speeds of
5 mph (8 km/h) or less. Whenever the trans -
mission remains in NEUTRAL (N) for more
than two seconds, you must press the brake
pedal to engage DRIVE or REVERSE.

Push the ESC OFF switch, to place the
Electronic Stability Control (ESC) system in
“Partial Off” mode, before rocking the vehicle

Ú
page 274. Once the vehicle has been freed,
push the ESC OFF switch 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 transmission 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 over -
heating 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 occurring).

350IN CASE OF EMERGENCY
TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled vehicle using a commercial towing service. If the transmission and drivetrain are operable,
disabled vehicles may also be towed as described Ú page 215.
Proper towing or lifting equipment is required to
prevent damage to your vehicle. Use only tow
bars and other equipment designed for this
purpose, following equipment manufacturer’s
instructions. Use of safety chains is mandatory.
Attach a tow bar or other towing device to main
structural members of the vehicle, not to
fascia/bumpers or associated brackets. State
and local laws regarding vehicles under tow
must be observed. If you must use the accessories (wipers,
defrosters, etc.) while being towed, the ignition
must be in the ON/RUN mode, not the ACC
mode.
If the key fob is unavailable or the vehicle's
battery is discharged, Ú

TWO-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 the rear wheels on the ground)
under the following conditions:
The transmission must be in NEUTRAL
Ú page 348.
The towing speed must not exceed 30 mph
(48 km/h).
The towing distance must not exceed
15 miles (24 km) for 6–speed transmission,
or 30 miles (48 km) for 8–speed transmis -
sion.
If the transmission is not operable, or the
vehicle must be towed faster than 30 mph
(48 km/h) or farther than 15 miles (24 km) for
6–speed transmission, or 30 miles (48 km) for 8–speed transmission, tow with the rear wheels
OFF the ground. Acceptable methods are to tow
the vehicle on a flatbed, or with the front wheels raised and the rear wheels on a towing dolly, or
(when using a suitable steering wheel stabilizer
to hold the front wheels in the straight position)
with rear wheels raised and the front wheels
ON
the ground.FOUR-WHEEL DRIVE MODELS

FCA US LLC recommends towing with all wheels
OFF the ground. Acceptable methods are to tow
the vehicle on a flatbed or with one end of vehicle
raised and the opposite end on a towing dolly.

If flatbed equipment is not available, and the
transfer case is operable, the vehicle may be
towed (in the forward direction, with ALL wheels
on the ground), IF the transfer case is in
NEUTRAL and the transmission is in PARK
Ú page 215.
CAUTION!
Towing this vehicle in violation of the above
requirements can cause severe engine and/
or transmission damage. Damage from
improper towing is not covered under the New
Vehicle Limited Warranty.
CAUTION!
Front or rear wheel lifts must not be used
(if the remaining wheels are on the ground).
Internal damage to the transmission or
transfer case will occur if a front or rear
wheel lift is used when towing.
Towing this vehicle in violation of the above
requirements can cause severe transmis -
sion and/or transfer case damage.

SERVICING AND MAINTENANCE
SCHEDULED SERVICING — GASOLINE
ENGINE
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.
Under no circumstances should oil change
intervals exceed 8,000 miles (13,000 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. Rotate at the
first sign of irregular wear.
Check the fluid levels of the coolant reservoir,
brake master cylinder, power steering and
automatic transmission (six-speed only), and
fill as needed.

Check function of all interior and exterior lights.

354SERVICING AND MAINTENANCE
MAINTENANCE PLAN
Refer to the maintenance plan on the following
pages for required maintenance. More frequent
maintenance may be needed in severe
conditions, such as dusty areas and very short
trip driving. In some extreme conditions,
additional maintenance not specified in the
maintenance schedule may be required.
NOTE:
Using white lithium grease, lubricate the door
hinge pivot joints twice a year to prevent prema-
ture wear.
At Every Oil Change Interval As Indicated By Oil Change Indicator System:
Change oil and filter.
Rotate the tires. Rotate at the first sign of
irregular wear, even if it occurs before the
oil indicator system turns on.
Inspect engine cooling system protection
and hoses.
Inspect exhaust system.
Inspect engine air cleaner filter if using in
dusty or off-road conditions. Replace the
engine air cleaner filter, if necessary.
Inspect battery and clean and tighten termi -
nals as required.
Inspect the CV/Universal joints.
Inspect automatic transmission fluid if
equipped with dipstick.
Inspect brake pads, shoes, rotors, drums,
hoses and parking brake.
At Every Oil Change Interval As Indicated
By Oil Change Indicator System:
Inspect front end, and lubricate — If
equipped with serviceable fittings.
Inspect and replace the Evaporative
System Fresh Air Filter as necessary,
replacement may be more frequent if
vehicle is operated in extreme dusty
conditions.
