SERVICING AND MAINTENANCE
SCHEDULED SERVICING
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 scheduled maintenance.
Based on engine operation conditions, the oil
change

indicator message will illuminate in the
instrument cluster. This means that service is
required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow and
extremely hot or cold ambient temperatures will
influence when the “Change Oil” or “Oil Change
Required” message is displayed. Have your vehicle
serviced as soon as possible, within the next
500 miles (805 km). An authorized dealer will reset the oil change
indica

tor message after completing the scheduled
oil change.
NOTE:
Under no circumstances should oil change
inter v
als exceed 10,000 miles (16,000 km),
1 year or 350 hours of engine run time, whichever
c omes f

irst. The 350 hours of engine run or idle
time is generally only a concern for fleet
customers.
NOTE:
The Oil Change Indicator will not illuminate under
these
conditions. Once A Month Or Before A Long Trip:
Check engine oil level.
Check windshield washer fluid level.
Check the tire inflation pressures and look for
unusual wear or damage.
Check the fluid levels of the coolant reservoir,
and brake master cylinder reservoir, and fill as
needed.
Check function of all interior and exterior lights.

1. The Uconnect box (telematics box) battery replacement has to be done every five years, regardless of mileage.2. Always only use the fluids shown in the handbook for topping up after having checked that the system is not damaged.
3. The maximum mileage is 75,000 mile s (120,000 km). The belt must be replaced every six years, regardless of distance traveled. If the vehicle is used in heavy conditions (dusty
areas,
cold climates, urban driving, long periods of idling), the maximum mileage is 37,500 miles (60,000 km). The belt must be replaced every four years regardless of the mileage.
4. The oil and oil filter replacement must be carried out when indicated by a warning light or message on the instrument panel, or in any case should not exceed one year or
10,0 0

0 miles (16,000 km).
5. Always only use the fluids shown in the handbook for topping up after having checked that the system is not damaged.
6. If

the engine oil quality detected by the vehicle diagnostics is lower than 20%, it is advisable to replace the engine oil and engine filter in order to avoid another service operation
afte r
a short time.
7. The spark plug change is distance based only, yearly intervals do not apply. The following are essential to ensure correct operation and prevent serious damage to the engine:
Only use spark plugs of the same make and type which are especially certified for such engines
Ú page 345 .
 Strictly comply with the spark plug replacement interval given in the “Maintenance Schedule” for spark plug replacement.
 Contact an authorized dealer if you have any questions.
8. Th e

engine air cleaner filter should be inspected at every oil change if used in dusty areas.
9. The brake fluid change interval is time based only, mileage intervals do not apply.

(Continued)
Keep the front of the radiator clean. If your
vehicle is equipped with air conditioning, keep
the front of the condenser clean.
Do not change the thermostat for Summer or
Winter operation. If replacement is ever neces-
sary, install ONLY the correct type thermostat.
O ther

designs may result in unsatisfactory
engine cooling performance, poor gas mileage,
and increased emissions.
BRAKE SYSTEM
In order to ensure brake system performance, all
brake system components should be inspected
periodically Ú page 287.
Brake Master Cylinder
The fluid level in the master cylinder should be
checked when performing under hood services, or
immediately if the Brake Warning Light is on.
Be sure to clean the top of the master cylinder area
before

removing the cap. If necessary, add fluid to
bring the fluid level up to the requirements
described on the brake fluid reservoir. Fluid level
can be expected to fall as the brake pads wear. The
brake fluid level should be checked when the pads
are replaced. However, low fluid level may be
caused by a leak and a checkup may be needed.
Use only manufacturer's recommended brake fluid
Ú page 345.
WARNING!
Riding the brakes can lead to brake failure and
possibly a collision. Driving with your foot resting
or riding on the brake pedal can result in
abnormally high brake temperatures, excessive
lining wear, and possible brake damage. Riding
the brakes may also reduce braking capacity in
an emergency.WARNING!
Use only manufacturer’s recommended brake
fluid
Ú page 345. Using the wrong type of
brake fluid can severely damage your brake
system
and/or impair its performance. The
proper type of brake fluid for your vehicle is
also identified on the original factory installed
hydraulic master cylinder reservoir.
To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that
has been in a tightly closed container. Keep
the master cylinder reservoir cap secured at
all times. Brake fluid in an open container
absorbs moisture from the air resulting in a
lower boiling point. This may cause it to boil
unexpectedly during hard or prolonged
braking, resulting in sudden brake failure. This
could result in a collision.
Overfilling the brake fluid reservoir can result
in spilling brake fluid on hot engine parts,
causing the brake fluid to catch fire. Brake
fluid can also damage painted and vinyl
surfaces, care should be taken to avoid its
contact with these surfaces.
CAUTION!
Use of improper brake fluids will affect overall
clutch system performance. Improper brake
fluids may damage the clutch system resulting in
loss of clutch function and the ability to shift the
transmission.
WARNING!

342 TECHNICAL SPECIFICATIONS
Tighten the wheel bolts in a star pattern until each
bolt has been tightened twice. Ensure that the
socket is fully engaged on the lug nut/bolt.

Torque Patterns

After 25 miles (40 km), check the wheel bolt
torque

to be sure that all the lug nuts/bolts are
properly tightened.
FUEL REQUIREMENTS
While operating on gasoline with the required
octane number, hearing a light knocking sound
from the engine is not a cause for concern.
However, if the engine is heard making a heavy
knocking sound, see an authorized dealer
immediately. Use of gasoline with a lower than
recommended octane number can cause engine
failure and may void or not be covered by the New
Vehicle Limited Warranty.
Poor quality gasoline can cause problems such as
hard s

tarting, stalling, and hesitations. If you
experience these symptoms, try another brand of
gasoline before considering service for the vehicle.
1.3L TURBO ENGINE
This engine is designed to meet all
emission regulations, and provide
s a t
is
f
actory fuel economy and
performance, when using high-quality
unleaded regular gasoline having an octane rating
of 87, as specified by the (R+M)/2 Method.
The use of a 91 or higher octane premium gasoline
will a

llow these engines to operate to optimal
performance. This increase in performance is most
noticeable in hot weather or other heavier load
conditions, such as towing.
REFORMULATED GASOLINE
Many areas of the country require the use of
cleaner burning gasoline referred to as
“reformulated gasoline”. Reformulated gasoline
contains oxygenates and are specifically blended
to reduce vehicle emissions and improve air
quality.
The use of reformulated gasoline is recommended.
Proper l

y blended reformulated gasoline will
provide improved performance and durability of
engine and fuel system components.
GASOLINE/OXYGENATE BLENDS
Some fuel suppliers blend unleaded gasoline with
oxygenates such as ethanol.
WARNING!
To avoid the risk of forcing the vehicle off the
jack, do not fully tighten the wheel bolts until the
vehicle has been lowered. Failure to follow this
warning may result in serious injury.
CAUTION!
DO NOT use E-85, gasoline containing methanol,
or gasoline containing more than 15% ethanol
(E-15). Use of these blends may result in starting
and drivability problems, damage critical fuel
system components, cause emissions to exceed
the applicable standard, and/or cause the
Malfunction Indicator Light to illuminate. Please
observe pump labels as they should clearly
communicate if a fuel contains greater than
15% ethanol (E-15).
