IN CASE OF EMERGENCY

5. While holding the locking tab in the

disengaged position, pull the tether strap to

rotate the lever rearward, until it locks in place

pointing towards the driver's seat. Release the

locking tab and verify that the Manual Park

Release lever is locked in the released

position.

6. The vehicle is now out of PARK and can be

towed. Release the parking brake only when

the vehicle is securely connected to a tow

vehicle.

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 transmis

-

sion, shifts between DRIVE and REVERSE 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 or REVERSE.



Push the ESC OFF button, to place the Electronic

Stability Control (ESC) system in “Partial Off”

mode, before rocking the vehicle

Ú

page 236.

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 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 182.

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,

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



The towing speed must not exceed 30 mph

(48 km/h).



The towing distance must not exceed 15 miles

(24 km) for six speed transmission, or 30 miles

(48 km) for eight speed transmission.

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 six speed

transmission, or 30 miles (48 km) for eight 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.

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 auto

-

matic transmission (6-Speed only), and fill as

needed.



Check function of all interior and exterior lights.

NOTE:

Using white lithium grease, lubricate the door hinge pivot joints twice a year to prevent premature wear.

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 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.
