STOP/START SYSTEM —
DIESEL MODELS ONLY
The Stop/Start function is developed to save
fuel and reduce emissions. The system will
stop the engine automatically during a
vehicle stop if the required conditions are
met. Releasing the brake pedal or pressing
the accelerator pedal on an automatic trans -
mission or pressing the clutch pedal on a
manual transmission will automatically
restart the engine.
Automatic Mode

The Stop/Start feature is enabled after every
normal customer engine start. It will remain in
STOP/START NOT READY until you drive
forward with a vehicle speed greater than 4 mph (7 km/h). At that time, the system will
go into STOP/START READY and if all other
conditions are met, can go into a STOP/START
AUTOSTOP ACTIVE “Autostop” mode.

To Activate The Autostop Mode, The Following
Must Occur:
The system must be in STOP/START
READY state. A STOP/START READY
message will be displayed in the instru
-
ment cluster display within the Stop/Start
section. Refer to “Instrument Cluster
Display” in “Getting To Know Your Instru -
ment Panel” in your Owner’s information
for further details.
The vehicle must be completely stopped.
The gear selector must be in DRIVE and
the brake pedal depressed (automatic
transmission) or the gear selector must be
in NEUTRAL and the clutch pedal must be
fully released (manual transmission).
The engine will shut down, the tachometer
will move to the zero position and the Stop/
Start telltale will illuminate indicating you
are in Autostop. While in Autostop, the
Climate Controls system may automatically
adjust airflow to maintain cabin comfort.
Customer settings will be maintained upon
return to an engine running condition.

Possible Reasons The Engine Does Not
Autostop
Prior to engine shut down, the system will
check many safety and comfort conditions to
see if they are fulfilled. Detailed information
about the operation of the Stop/Start system
may be viewed in the instrument cluster
Stop/Start Screen. In the following situations
the engine will not stop:
Driver’s seat belt is not buckled.
Driver’s door is not closed.
Battery temperature is too warm or cold.
The vehicle is on a steep grade.
Cabin heating or cooling is in process and
an acceptable cabin temperature has not
been achieved.
HVAC is set to full defrost mode at a high
blower speed.
Engine has not reached normal operating
temperature.
Battery charge is low.
The transmission is not in DRIVE (auto-
matic transmission) or NEUTRAL (manual
transmission).
Hood is open.
Vehicle is in 4WD LOW transfer case
mode.
Exhaust system regeneration in process.
Other Factors Which Can Inhibit Autostop
Include:
Fuel level.
Accelerator pedal input (automatic trans-
mission only).
Engine temperature too high.
It may be possible for the vehicle to be driven
several times without the Stop/Start system
going into a STOP/START READY state
under more extreme conditions of the items
listed above.
To Start The Engine While In Autostop
Mode
Automatic Transmission:

While in DRIVE, the engine will start when the
brake pedal is released or the throttle pedal is
depressed. The transmission will automatically
re-engage upon engine restart. During this tran -
sition, the brakes will hold the vehicle to avoid
undesired vehicle movement.
Manual Transmission:

When the gear selector is in NEUTRAL, the
engine will start when the clutch pedal is
pressed. The vehicle will go into STOP/START
SYSTEM NOT READY mode until the vehicle
speed is greater than 4 mph (7 km/h).

Conditions That Will Cause The Engine To Start
Automatically While In Autostop Mode:

The transmission gear selector is moved
from DRIVE to REVERSE or NEUTRAL.
To maintain cabin temperature comfort.
HVAC is set to full defrost mode.
Battery voltage drops too low.
Low brake vacuum (e.g. after several brake
pedal applications).
Stop/Start OFF switch is pushed.
4WD system is put into 4WD LOW mode.
The emissions system requires it.
A Stop/Start system error occurs.

Never have any smoking materials lit in
or near the vehicle when the fuel door is
open or the tank is being filled.
Never add fuel when the engine is
running. This is in violation of most
countries regulations and may cause the
“Malfunction Indicator Light” to turn on.
Do not apply any object/cap to the end of
the filler which is not provided for the
car. The use of non-compliant objects/
plugs could cause a pressure increase
inside the tank, resulting in dangerous
situations.
A fire may result if fuel is pumped into a

Adblue® (UREA) — If Equipped
The vehicle is equipped with an UREA injec-
tion system and Selective Catalytic Reduc -
tion to meet emission standards. These two
systems ensure compliance with the diesel
emissions requirements; at the same time,
they ensure fuel-efficiency, handling, torque
and power. For messages and system warn -
ings, refer to the “Warning Lights And
Messages” in the “Getting To Know Your
Instrument Panel” section. AdBlue® (UREA)
is a very stable product with a long shelf life.
Stored at temperatures LOWER than 90 °F
(32 °C), it has a shelf life of at least one year.
For more information on the AdBlue® liquid
type, see the “Fluids and lubricants” in the
“Technical specifications” section. The
vehicle is equipped with an automatic
AdBlue® heating system when the engine
starts allowing the system to work correctly
at temperatures lower than 12 °F (-11 °C).
NOTE:
AdBlue® freezes at temperatures lower than
12 °F (-11 °C).
AdBlue® (UREA) Storage
AdBlue® (UREA) is considered a very stable
product with a long shelf life. If AdBlue®
(UREA) is kept in temperatures between 10°
and 90°F (-12° and 32°C), it will last a
minimum of one year.
AdBlue® (UREA) is subject to freezing at the
lowest temperatures. For example, AdBlue®
(UREA) may freeze at temperatures at or
below 12° F (-11° C). The system has been
designed to operate in this environment.
NOTE:
When working with AdBlue® (UREA), it is
important to know that:
Any containers or parts that come into
contact with AdBlue® (UREA) must be
AdBlue® (UREA) compatible (plastic or
stainless steel). Copper, brass, aluminum,
iron or non-stainless steel should be
avoided as they are subject to corrosion by
AdBlue® (UREA).
If AdBlue® (UREA) is spilled, it should be
wiped up completely.
Adding AdBlue® (UREA)
Preliminary Conditions
AdBlue® (UREA) freezes at temperatures
lower than 12° F (-11° C). If the car stands
for a long time at this temperature refilling
could be difficult. For this reason, it is
advised to park the vehicle in a garage and/
or heated environment and wait for the
UREA to return to liquid state before topping
up.
Proceed as follows:
Park the car on flat ground and stop the
engine by placing the ignition in the OFF
position.
Open the fuel door, undo and remove the
cap (blue) from the AdBlue® (UREA)

You can fill up at any AdBlue® (UREA)
distributor.
Proceed as follows:
Insert the AdBlue® (UREA) nozzle in the
filler, start refilling and stop refilling at the
first shut-off (the shut-off indicates that
the AdBlue® (UREA) tank is full). Do not
proceed with the refilling, to prevent
spillage of AdBlue® (UREA).
Extract the nozzle. Refilling With Containers
Proceed as follows:
Check the expiration date.
Read the advice for use on the label before
pouring the content of the bottle into the
AdBlue® (UREA) tank.
If systems which cannot be screwed in
(e.g. tanks) are used for refilling, after the
indication appears on the instrument
panel display refer to “Warning lights And
Messages” in the “Getting To Know Your
Instrument Panel” for further information,
fill the AdBlue® (UREA) tank with no
more than 1.6 Gallons (6 liters).
If containers which can be screwed to the
filler are used, the reservoir is full when
the AdBlue® (UREA) level in the
container stops pouring out. Do not
proceed further.
Operations After Refilling
Proceed as follows:
Fit the cap back on the AdBlue® (UREA)
filler by turning it clockwise and screwing
it completely.
Place the ignition to RUN (it is not neces-
sary to start the engine).
Wait for the indication on the instrument
panel to switch off before moving the car.
The indication may stay on for a few
seconds to approximately half a minute. If
the engine is started and the car is moved,
the indication will remain on for longer.
This will not compromise engine opera-
tion.
If the AdBlue® (UREA) was topped up
when the tank was empty, wait for
2 minutes before starting the engine.
