2020 JEEP WRANGLER UNLIMITED towing

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.

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.

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.

Severe Duty Conditions
Change the engine oil and engine oil filter at
every 4,500 miles (7,500 km) or 6 months
if using your vehicle under any of the
following severe duty conditions:
Stop and go driving.
Driving in dusty conditions.
Short trips of less than 10 miles (16 km).
Trailer towing.
Taxi, police, or delivery service (commer-

Off-road or desert operation.
Scheduled Servicing — Diesel 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 engine oil
replacement.
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.

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 will influence when the
“Oil Change Required” message is displayed. Severe Operating Conditions can cause the
change oil message to illuminate as earlier than
specified. Have your vehicle serviced as soon
as possible, within the next 500 miles
(805 km).

NOTE:
The actual interval for changing engine oil
and replacing the engine oil filter depends
on the vehicle usage conditions, and is
signaled by the warning light or message
in the instrument panel. In any case, it
must never exceed 12,500 miles
(20,000 km) or 1 year
Flush and replace the engine coolant at
120 months or 150,000 miles (240,000 km)
whichever comes first.
The maximum mileage is 75,000 mi
(120,000 km). The belt must be replaced
every 5 years regardless of distance trav-
eled. The timing and accessory belts must be
changed every 37,500 miles (60,000 km) or
3 years for particularly demanding use
(dusty areas, severe weather conditions,
very low or very high temperatures for
extended periods, city driving, long periods
of idling). Under no circumstances should
these intervals be exceeded.
WARNING!
You can be badly injured working on or
around a motor vehicle. Do only service
work for which you have the knowledge
and the right equipment. If you have any
doubt about your ability to perform a
service job, take your vehicle to a compe-
tent mechanic.
Failure to properly inspect and maintain
your vehicle could result in a component
malfunction and effect vehicle handling
and performance. This could cause an
accident.

(Continued)
Under normal operating conditions, the cata-
lytic converter will not require maintenance.
However, it is important to keep the engine
properly tuned to ensure proper catalyst
operation and prevent possible catalyst
damage.
NOTE:
Intentional tampering with emissions control
systems can result in civil penalties being
assessed against you.
In unusual situations involving grossly
malfunctioning engine operation, a
scorching odor may suggest severe and
abnormal catalyst overheating. If this occurs,
stop the vehicle, turn off the engine and
allow it to cool. Service, including a tune-up
to manufacturer's specifications, should be
obtained immediately.
To minimize the possibility of catalytic
converter damage:
Do not interrupt the ignition when the
transmission is in gear and the vehicle is
in motion.
Do not try to start the vehicle by pushing
or towing the vehicle.
Do not idle the engine with any ignition
components disconnected or removed,
such as when diagnostic testing, or for
prolonged periods during very rough idle or
malfunctioning operating conditions.
Cooling System

A hot exhaust system can start a fire if you
park over materials that can burn. Such
materials might be grass or leaves coming
into contact with your exhaust system. Do not
park or operate your vehicle in areas where
your exhaust system can contact anything
that can burn.

CAUTION!

The catalytic converter requires the use of
unleaded fuel only. Leaded gasoline will
destroy the effectiveness of the catalyst as an
emissions control device and may seriously
reduce engine performance and cause
serious damage to the engine.
Damage to the catalytic converter can result
if your vehicle is not kept in proper operating
condition. In the event of engine malfunc -
tion, particularly involving engine misfire or
other apparent loss of performance, have your
vehicle serviced promptly. Continued opera-
tion of your vehicle with a severe malfunction
could cause the converter to overheat,
resulting in possible damage to the converter
and vehicle.

WARNING! (Continued)
WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam
from your radiator. If you see or hear
steam coming from under the hood, do
not open the hood until the radiator has
had time to cool. Never open a cooling
system pressure cap when the radiator or
coolant bottle is hot.
Keep hands, tools, clothing, and jewelry
away from the radiator cooling fan when
the hood is raised. The fan starts auto-
matically and may start at any time,
whether the engine is running or not.

Tire Types
All Season Tires — If Equipped
All Season tires provide traction for all
seasons (Spring, Summer, Autumn, and
Winter). Traction levels may vary between
different all season tires. All season tires can
be identified by the M+S, M&S, M/S or MS
designation on the tire sidewall. Use all
season tires only in sets of four; failure to do
so may adversely affect the safety and
handling of your vehicle.

Summer Or Three Season Tires — If Equipped

Summer tires provide traction in both wet
and dry conditions, and are not intended to
be driven in snow or on ice. If your vehicle is
equipped with Summer tires, be aware these
tires are not designed for Winter or cold
driving conditions. Install Winter tires on
your vehicle when ambient temperatures are
less than 40°F (5°C) or if roads are covered
with ice or snow. For more information,
contact an authorized dealer.

Summer tires do not contain the all season desig-
nation or mountain/snowflake symbol on the tire
sidewall. Use Summer tires only in sets of four;
failure to do so may adversely affect the safety
and handling of your vehicle.

Snow Tires
Some areas of the country require the use of
snow tires during the Winter. Snow tires can
be identified by a “mountain/snowflake”
symbol on the tire sidewall.
If you need snow tires, select tires
equivalent in size and type to the
original equipment tires. Use snow
tires only in sets of four; failure to
do so may adversely affect the safety and
handling of your vehicle.
Snow tires generally have lower speed ratings
than what was originally equipped with your
vehicle and should not be operated at
sustained speeds over 75 mph (120 km/h).
For speeds above 75 mph (120 km/h) refer
to original equipment or an authorized tire
dealer for recommended safe operating
speeds, loading and cold tire inflation pres -
sures. While studded tires improve performance on
ice, skid and traction capability on wet or dry
surfaces may be poorer than that of
non-studded tires. Some states prohibit
studded tires; therefore, local laws should be
checked before using these tire types.
Spare Tires — If Equipped
NOTE:
For vehicles equipped with Tire Service Kit
instead of a spare tire, please refer to “Tire
Service Kit” in “In Case Of Emergency” in
the Owner’s Manual for further information.
Refer to the “Towing Requirements - Tires”
in “Starting And Operating” in the Owner’s
Manual for restrictions when towing with a
spare tire designated for temporary emer
-
gency use.
WARNING!
Do not use Summer tires in snow/ice
conditions. You could lose vehicle control,
resulting in severe injury or death. Driving
too fast for conditions also creates the
possibility of loss of vehicle control.
CAUTION!
Because of the reduced ground clearance,
do not take your vehicle through an
automatic car wash with a compact or
limited use temporary spare installed.
Damage to the vehicle may result.
