gas mileage JEEP WRANGLER UNLIMITED 2019 Owner handbook (in English)

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).
