Once A Month Or Before A Long Trip
Check engine oil level.
Check windshield washer fluid level.
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.
Check the fluid levels of the coolant reser-
voir and brake master cylinder, fill as
needed.
Check function of all interior and exterior
lights.
Control and recovery of additive level for
AdBlue® Diesel emissions (UREA) (if
equipped). At Each Oil Change
Change the engine oil filter.
Inspect the brake hoses and lines.
Inspect for the presence of water in the
fuel filter/water separator unit.
Inspect air cleaner filter if using in dusty
or off-road conditions. Replace air cleaner
filter, if necessary.
Demanding Vehicle Use
Restore additive level for AdBlue® Diesel
emissions (UREA) (if equipped), when the
lamp is illuminated or the message on the
instrument panel.
Maintenance Plan — Diesel Engines
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.

(*) 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 12,000 miles
(20,000 km) or 1 year.
(**) Areas that are not dusty: recommended
maximum distance 75,000 mi
(120,000 km). The belt must be replaced
every 6 years, regardless of distance trav-
elled. Dusty areas and/or heavy conditions
(severe weather conditions, very low or very
high temperatures for extended periods,
urban driving, long periods of idling): the recommended maximum distance is
37,500 mi (60,000 km). The belt must be
replaced every 4 years, regardless of
distance travelled.
(***) The brake fluid change interval is time
based only, mileage intervals do not apply.
(°) Consumption of additive AdBlue®
(UREA) depends on the condition of use of
the vehicle and is indicated by LED and/or
message on the instrument panel.

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.

A/C Air Filter
See an authorized dealer for service.
Wiper Blades
Clean the rubber edges of the wiper blades
and the windshield and rear window periodi-
cally with a sponge or soft cloth and a mild
nonabrasive cleaner. This will remove accu -
mulations of salt, waxes, or road film, and
help reduce streaking and smearing.
Operation of the wipers on dry glass for long
periods may cause deterioration of the wiper
blades. Always use washer fluid when using
the wipers to remove salt or dirt from a dry
windshield or rear window.
Avoid using the wiper blades to remove frost
or ice from the windshield or rear window.
Make sure that they are not frozen to the
glass before turning them on to avoid
damaging the blade. Keep the wiper blade
out of contact with petroleum products such
as engine oil, gasoline, etc.
NOTE:
Life expectancy of wiper blades varies
depending on geographical area and
frequency of use. Poor performance of
blades may be present with chattering, marks, water lines or wet spots. If any of
these conditions are present, clean the wiper
blades or replace as necessary.
Exhaust System
The best protection against carbon monoxide
entry into the vehicle body is a properly
maintained engine exhaust system.
If you notice a change in the sound of the
exhaust system; or if the exhaust fumes can
be detected inside the vehicle; or when the
underside or rear of the vehicle is damaged;
have an authorized technician inspect the
complete exhaust system and adjacent body
areas for broken, damaged, deteriorated, or
mispositioned parts. Open seams or loose
connections could permit exhaust fumes to
seep into the passenger compartment. In
addition, have the exhaust system inspected
each time the vehicle is raised for lubrication
or oil change. Replace as required.
WARNING!
Exhaust gases can injure or kill. They
contain carbon monoxide (CO), which is
colorless and odorless. Breathing it can
make you unconscious and can eventu
-
ally poison you. To avoid breathing CO,
refer to “Safety Tips” in “Safety” for
further information.
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 cata-
lyst as an emissions control device and
may seriously reduce engine perfor -
mance and cause serious damage to the
engine.

NOTE:
Wheel Valve Stem must be replaced as well
when installing new tires due to wear and
tear in existing tires.
Keep dismounted tires in a cool, dry place
with as little exposure to light as possible.
Protect tires from contact with oil, grease,
and gasoline.
Replacement Tires
The tires on your new vehicle provide a
balance of many characteristics. They should
be inspected regularly for wear and correct
cold tire inflation pressures. The manufac-
turer strongly recommends that you use tires
equivalent to the originals in size, quality
and performance when replacement is
needed. Refer to the paragraph on “Tread
Wear Indicators” in this section. Refer to the
Tire and Loading Information placard or the
Vehicle Certification Label for the size desig -
nation of your tire. The Load Index and
Speed Symbol for your tire will be found on
the original equipment tire sidewall.
It is recommended to replace the two front
tires or two rear tires as a pair. Replacing just
one tire can seriously affect your vehicle’s
handling. If you ever replace a wheel, make
sure that the wheel’s specifications match
those of the original wheels. It is recommended you contact an authorized
tire dealer or original equipment dealer with
any questions you may have on tire specifica
-
tions or capability. Failure to use equivalent
replacement tires may adversely affect the
safety, handling, and ride of your vehicle.
Tire Types
All Season Tires — If Equipped
All Season tires provide traction for all
seasons (Spring, Summer, Fall, and Winter).
Traction levels may vary between different all
season tires. All season tires can be identi -
fied by the M+S, M&S, M/S or MS designa -
tion 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.
WARNING!
Do not use a tire, wheel size, load rating,
or speed rating other than that specified
for your vehicle. Some combinations of
unapproved tires and wheels may change
suspension dimensions and performance
characteristics, resulting in changes to
steering, handling, and braking of your
vehicle. This can cause unpredictable
handling and stress to steering and
suspension components. You could lose
control and have a collision resulting in
serious injury or death. Use only the tire
and wheel sizes with load ratings
approved for your vehicle.
Never use a tire with a smaller load index
or capacity, other than what was origi -
nally equipped on your vehicle. Using a
tire with a smaller load index could result
in tire overloading and failure. You could
lose control and have a collision.
Failure to equip your vehicle with tires
having adequate speed capability can
result in sudden tire failure and loss of
vehicle control.
CAUTION!
Replacing original tires with tires of a
different size may result in false
speedometer and odometer readings.
