SERVICING AND MAINTENANCE

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-
cial service).
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.

Check the fluid levels of the coolant reservoir
and brake master cylinder, fill as needed.

Check function of all interior and exterior lights.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.

Required Maintenance Intervals
Refer to the maintenance plan on the
following pages for the required maintenance
intervals.
NOTE:
Once you have carried out the last intervention in the table, continue with the scheduled servicing, maintaining the frequency indicated in
the plan by marking each operation 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.

At Every Oil Change Interval As Indicated By Oil Change Indicator System:
Change oil and filter
Rotate the tires. Rotate at the first sign of irregular wear, even if it occurs before the oil indicator system turns on
Inspect battery and clean and tighten terminals as required
Inspect the CV/Universal joints
Inspect brake pads, shoes, rotors, drums, hoses and park brake

The left-hand control is a rocker-type switch
with a push-button in the center. The func-
tion of the left-hand control is different
depending on which mode you are in.
The following describes the left-hand control
operation in each mode.
Radio Operation
Pushing the top of the switch will Seek Up
for the next listenable station, and pushing
the bottom of the switch will Seek Down for
the next listenable station.
The button located in the center of the
left-hand control will make the radio switch
between various modes available (AM/FM/
DAB, etc.).
Media Mode
Pushing the top of the switch once goes to
the next track on the selected media (AUX/
USB/Bluetooth®). Pushing the bottom of the
switch once goes to the beginning of the
current track or to the beginning of the
previous track if it is within eight seconds
after the current track begins to play.
AUX/USB/MP3 CONTROL
The Media Hub is located on the instrument
panel, below the climate controls. Behind
the media hub access door, the Media Hub
contains one AUX port, a Type C USB Port
and one standard USB Port. Both USB Ports
allow you to play music from MP3 players /
smartphones or USB devices through the
vehicle’s sound system.
The Smart Charging USB ports provide
power to your device up to an hour after the
vehicle is turned off.
NOTE:
Two devices can be plugged in at the same
time and both ports will provide charging
capabilities. Only one port can transfer
data to the system at a time. A pop-up will
appear and allow you to select the device
transferring data.
Both ports share a single data connection.
The user cannot switch between Type A or
Type C. For example, if a device is plugged into the
Type A USB port and another device is
plugged into the Type C USB port, a message
will appear and allow you to select which
device to use.
