TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled vehicle using a commercial towing service. If the transmission and drivetrain are oper-
able, disabled vehicles may also be towed as described under “Recreational Towing” in the “Starting And Operating” section.

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 bumpers or associ -
ated brackets. State and local laws regarding vehi -
cles under tow must be observed.

If you must use the accessories (wipers,
defrosters, etc.) while being towed, the igni -
tion must be in the ON/RUN position, not the
ACC position. If the vehicle's battery is discharged, refer to
“Manual Park Release” in this chapter for
instructions on shifting the automatic trans
-
mission out of PARK in order to move the
vehicle.

IN CASE OF EMERGENCY
208
(Continued)
Four–Wheel Drive Models
The manufacturer 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). Refer to “Recreational Towing” in
“Starting And Operating” for detailed
instructions.
Without The Key Fob
Special care must be taken when the vehicle
is towed with the ignition in the OFF mode.
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.
Tow Eye Usage
Your vehicle is equipped with a tow eye that
can be used to move a disabled vehicle.
When using a tow eye be sure to follow the
“Tow Eye Usage Precautions” and the
“Towing A Disabled Vehicle” instructions in
this section.
The tow eyes are mounted below the front
and rear bumpers.
Front Tow Eye Rear Tow Eye
Tow Eye Usage Precautions
CAUTION!
Front or rear wheel lifts must not be used
(if the remaining wheels are on the
ground). Internal damage to the trans-
mission 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
transmission and/or transfer case
damage. Damage from improper towing
is not covered under the New Vehicle
Limited Warranty.
WARNING!
Stand clear of vehicles when pulling with
tow eyes.
Do not use a chain with a tow eye. Chains
may break, causing serious injury or
death.
Do not use a tow strap with a tow eye.
Tow straps may break or become disen -
gaged, causing serious injury or death.
Failure to follow proper tow eye usage
may cause components to break
resulting in serious injury or death.

onto a flatbed truck.Tow Eye Warning Label
ENHANCED ACCIDENT
RESPONSE SYSTEM (EARS)
This vehicle is equipped with an Enhanced
Accident Response System.
Please refer to “Occupant Restraint
Systems” in “Safety” for further information
on the Enhanced Accident Response System
(EARS) function.
EVENT DATA RECORDER
(EDR)
This vehicle is equipped with an Event Data
Recorder (EDR). The main purpose of an
EDR is to record data that will assist in
understanding how a vehicle’s systems
performed under certain crash or near
crash-like situations, such as an air bag
deployment or hitting a road obstacle.
Please refer to “Occupant Restraint
Systems” in “Safety” for further information
on the Event Data Recorder (EDR).
The brake and steering power assist
systems will not function while the
vehicle is being towed. You will, there-
fore, need to apply more force on the
brake pedal and steering wheel. Do not
use flexible ropes when towing, and
avoid jerky movements. Do not start the
engine while towing the car. Before
tightening the ring, clean the threaded
housing thoroughly. Make sure that the
ring is fully screwed into the housing
before towing the car.
CAUTION!
The tow eye must only be used for road -
side emergencies. Use with an appro-
priate device in accordance with highway
code (a rigid bar) to maneuver the
vehicle in preparation for transport via a
tow truck.
The tow eye must not be used to move
the vehicle off the road or where there
are obstacles.
Do not use the tow eyes for tow truck
hookup or highway towing.
WARNING! (Continued)
Do not use the tow eye to free a stuck
vehicle. Refer to the “Freeing A Stuck
Vehicle” section for further information.
Please refer to the “Towing A Disabled
Vehicle” section for detailed
instructions. Damage to your vehicle
may occur if these guidelines are not
followed.

SERVICING AND MAINTENANCE
SCHEDULED SERVICING
Correct servicing is crucial for guaranteeing a
long life for the car under the best condi-
tions. For this reason, Jeep has planned a
series of checks and services at fixed
distance intervals and, where provided, at
fixed time intervals, as described in the
Scheduled Servicing plan. To keep the car’s
efficiency in tip-top condition, in the
following Scheduled Service plan pages a
few additional checks are listed that should
be carried out more frequently with respect
to the normal coupon redemption schedule.
Scheduled Servicing is offered by all autho -
rized dealerships according to fixed time or
mileage intervals. If, during each operation,
in addition to the ones scheduled, the need
arises for further replacements or repairs,
these may be carried out with the owner's
explicit agreement only.
The technicians at your dealership know your
vehicle best, and have access to factory
trained information, genuine Mopar parts,
and specially designed electronic and
mechanical tools that can help prevent
future costly repairs. If your car is used
frequently for towing, the interval between
one scheduled servicing operation and the next should be reduced. More frequent main
-
tenance may be needed for vehicles in severe
operating conditions, such as dusty areas
and very short trip driving.
NOTE:
Scheduled Servicing interventions are set
out by the Manufacturer. Failure to have
them carried out may invalidate the
warranty. It is advised to inform an autho -
rized dealership of any small operating irreg -
ularities without waiting for the next service.
Scheduled Servicing — Gasoline Engine
The oil change indicator system (if
equipped) will remind you that it is time to
take your vehicle in for engine oil replace -
ment.
On vehicles equipped with instrument
cluster display, “Oil Change Required” will
be displayed and a single chime will sound,
indicating that an oil change is necessary.
On non-instrument cluster display equipped
vehicles, “Change Oil” will flash in the
instrument cluster odometer and a single
chime will sound, indicating that an oil
change is necessary. The oil change indicator message will illumi
-
nate approximately 7,000 miles
(11,200 km) after the most recent oil
change was performed. Have your vehicle
serviced as soon as possible, within
500 miles (800 km). However, an earlier oil
change at 4,500 miles (7,500 km) may be
required if the vehicle is operated under
“Severe Duty Conditions” later in this
section.
NOTE:
The oil change indicator message will not
monitor the time since the last oil change.
Change your vehicle's oil if it has been
12 months since your last oil change even
if the oil change indicator message is NOT
illuminated.
Change your engine oil more often if you
drive your vehicle off-road for an extended
period of time.
Under no circumstances should oil change
intervals exceed 7,500 miles
(12,000 km) or 12 months, whichever
comes first.
An authorized dealer will reset the oil change
indicator message after completing the
scheduled oil change.
2020_JEEP_JL_WRANGLER_UG_RHD_UK.book Page 210

211
Once A Month Or Before A Long Trip
Check the engine oil level about five
minutes after a fully warmed engine is
shut off. Checking the oil level while the
vehicle is on level ground will improve the
accuracy of the oil level reading. Add oil
only when the level is at or below the ADD
or MIN mark.
Check the windshield washer solvent and
add if required.
Check tire pressure and look for unusual
wear or damage. Rotate tires at the first
sign of irregular wear.
Inspect the battery and clean and tighten
the terminals as required.
Check the fluid levels of coolant reservoir,
brake master cylinder and power steering
and fill as needed.
Check all lights and other electrical items
for correct operation.At Each Oil Change
Change the engine oil filter.
Inspect the brake hoses and lines.
Inspect the CV/Universal joints.
Check tire pressure 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.
Required Maintenance Intervals
Refer to the Maintenance Plan on the
following pages for the required maintenance
intervals.
Maintenance Plan
NOTE:
Once you have carried out the last interven -
tion in the table, continue with the sched -
uled servicing, maintaining the frequency
indicated in the plan by marking each oper -
ation with a dot or dedicated note. Simply
restarting the maintenance from the start of
the plan may cause the allowed interval to be
exceeded for some operations.
CAUTION!
Failure to perform the required
maintenance items may result in damage
to the vehicle.
