IN CASE OF EMERGENCY351
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 position, not the ACC
position.
If the vehicle's battery is discharged, instructions
on shifting the automatic transmission out of
PARK (P) in order to move the vehicle Úpage 348.
FOUR–WHEEL DRIVE MODELS
FCA LLC US recommends towing with all wheels
OFF the ground. Acceptable methods are to tow
the vehicle on a flatbed or with one end of the
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 (N)
and the transmission is in PARK (P) (for automatic
transmissions) or in gear ( NOT in NEUTRAL , for
manual transmissions) Ú page 205.
WITHOUT THE KEY FOB
Special care must be taken when the vehicle is
towed with the ignition in the OFF position. The only
approved method of towing without the key fob is
with a flatbed truck. Proper towing equipment is
necessary to prevent damage to the vehicle.
EMERGENCY TOW HOOKS —
I
F EQUIPPED
If your vehicle is equipped with tow hooks, they are
mounted in the front and the rear fascia/bumpers.

Front Tow Hooks

NOTE:Depending on vehicle trim level, rear tow hooks
may vary.
CAUTION!
Do not use sling type equipment when towing.
Vehicle damage may occur.
When securing the vehicle to a flatbed truck,
do not attach to front or rear suspension
components. Damage to your vehicle may
result from improper towing.
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
approved requirements can cause severe
transmission and/or transfer case damage.
Damage from improper towing is not covered
under the New Vehicle Limited Warranty.

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, or 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).
On vehicles equipped with an instrument cluster
display, “Oil Change Required” will be displayed
and a single chime will sound, indicating that an oil
change is necessary. On vehicles not equipped with an instrument
cluster display, “Change Oil” will flash in the

necessary.
An authorized dealer will reset the oil change
indicator message after completing the scheduled
oil change. To reset the system follow the steps
described Ú
page 122.
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 pressures and look for unusual
wear or damage, rotate at the first sign of irreg
-
