2018 JEEP WRANGLER UNLIMITED mileage

SCHEDULED SERVICING
Correct servicing is crucial for guaranteeing a
long life for the car under the best conditions.
For this reason, Jeep has planned a series of
checks and services at fixed distance inter-
vals and, where provided, at fixed time inter-
vals, 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 redemp-
tion schedule. Scheduled Servicing is offered
by all authorized dealerships according to
fixed time or mileage intervals. If, during
each operation, in addition to the ones
scheduled, the need arises for further re-
placements 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 me-
chanical tools that can help prevent future
costly repairs. If your car is used frequently
for towing, the interval between one sched-uled servicing operation and the next should
be reduced. More frequent maintenance 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 authorized dealership of
any small operating irregularities without
waiting for the next service.
Scheduled Servicing — Gasoline Engine
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 dis-
played and a single chime will sound, indi-
cating that an oil change is necessary.
On non-instrument cluster display equipped
vehicles, “Change Oil” will flash in the in-
strument 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)
(except for 2.0L gasoline engine with GPF -
Gasoline Particulate Filter). However, an ear-
lier 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 (ex-
cept for 2.0L gasoline engine with GPF -
Gasoline Particulate Filter).

(*) 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 instru-
ment cluster. In any case, it must never
exceed two years. If the vehicle is used
mainly for city driving, change the engine oil
and filter every year.
(**) The brake fluid interval is time based
only, mileage intervals do not apply.
(***) 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 orvery high temperatures for extended periods,
city driving, long periods of idling). Under no
circumstances should these intervals be ex-
ceeded.
(°) Consumption of additive AdBlue (UREA)
depends on the condition of use of the ve-
hicle and is indicated by LED and/or message
on the instrument panel.

Component Fluid, Lubricant, or Genuine Part
Brake Master Cylinder We recommend you use DOT 3, SAE J1703 brake fluid. If DOT 3 brake fluid is not available
then TUTELA TOP4/S, FMVSS no. 116 DOT 4, ISO 4925 SAE J1704, or equivalent, is
acceptable.
If using DOT 4 brake fluid, the fluid must be changed every 24 months regardless of mileage.
Power Steering Reservoir We recommend you use TUTELA TRANSMISSION FORCE 4 fluid, or equivalent, meeting
requirement of FCA Material Standard 9.55550-AV4 or MS.9602.
FUEL CONSUMPTION AND
CO
2EMISSIONS
The fuel consumption and CO2emission
figures declared by the manufacturer are de-
termined on the basis of the type-approval
tests laid down by the applicable standards
in the country where the vehicle is registered.
The type of route, traffic conditions, weather
conditions, driving style, general condition of
the vehicle, trim level/equipment/ accesso-
ries, use of the climate control system, ve-
hicle load, presence of roof racks and othersituations that adversely affect the aerody-
namics or wind resistance lead to different
fuel consumption values than those mea-
sured.
The fuel consumption will only become more
regular after driving the first 1,864 miles
(3000 km).
To find the specific fuel consumption and
CO
2emission figures for this vehicle, please
refer to the data in the Certificate of Confor-
mity, and the related documentation that
accompanies the vehicle.
