Make sure that the electric park brake is engaged and that the transmission is in PARK (P) or NEUTRAL (N). Next, press the brake pedal,
and then push the engine START/STOP button.
Parking On Flammable Material
The catalytic converter develops high temperatures during operation. Do not park the vehicle on potential fire hazards such as: grass, dry
leaves, pine needles or other flammable material.
Respecting The Environment
The vehicle is fitted with a system that carries out a continuous diagnosis of the emission-related components in order to help protect the
environment (if equipped).
Electrical Accessories
If you decide to add electrical accessories after purchasing the vehicle, with the risk of gradually draining the battery, contact an autho -
rized dealer. They can calculate the overall electrical requirement and check that the vehicle's electric system can support the required
load.
Scheduled Servicing
Correctly performed maintenance procedures are essential for ensuring that your vehicle continuously maintains its quality in perfor -
mance and safety features, environmental friendliness, and low running costs.

mirrors, and fasten the seat belt correctly.
Never press the accelerator pedal before
starting the engine.
If necessary, messages indicating the starting
procedure will be shown in the display.
Starting Procedure
Proceed as follows:
1. Apply the Electric Park Brake (EPB) andplace the gear selector in PARK (P) or
NEUTRAL (N).
2. Fully press the brake pedal without touching the accelerator.
3. Briefly push the ignition button.
4. If the engine doesn't start within a few seconds, you need to repeat the proce -
dure.
If the problem persists, contact an authorized
dealer.
Remote Starting System
This system uses the key fob to start the
engine conveniently from outside the vehicle
while still maintaining security. The system
has a range of at least 300 feet (91 meters).
The remote starting system also activates the
climate control, the heated seats (if
equipped), and the heated steering wheel (if
equipped), depending on temperatures
outside and inside of the vehicle.

NOTE:

Obstructions between the vehicle and key fob
may reduce this range.
WARNING!
When leaving the vehicle, always remove
the key fob from the vehicle and lock your
vehicle.
Never leave children alone in a vehicle, or
with access to an unlocked vehicle.
Allowing children to be in a vehicle unat -
tended is dangerous for a number of
reasons. A child or others could be seri -
ously or fatally injured. Children should be
warned not to touch the parking brake,
brake pedal or the transmission gear
selector.
Do not leave the key fob in or near the
vehicle, or in a location accessible to chil -
dren. A child could operate power
windows, other controls, or move the
vehicle.
Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury or
death.
WARNING!
Never pour fuel or other flammable liquid
into the throttle body air inlet opening in
an attempt to start the vehicle. This could
result in flash fire causing serious
personal injury.
Do not attempt to push or tow your vehicle
to get it started. Vehicles equipped with an
automatic transmission cannot be started
this way. Unburned fuel could enter the
catalytic converter and once the engine
has started, ignite and damage the
converter and vehicle.
If the vehicle has a discharged battery,
booster cables may be used to obtain a
start from a booster battery or the battery
in another vehicle. This type of start can
be dangerous if done improperly

After Starting — Warming Up The Engine
Proceed as follows:
Travel slowly, letting the engine run at a
reduced RPM, without accelerating
suddenly.
It is recommended to wait until the digital
engine coolant temperature indicator starts
to rise for maximum performance.
Stopping The Engine
To stop the engine, proceed as follows:
1. Park the vehicle in a position that is notdangerous for oncoming traffic.
2. Engage the PARK (P) mode.
3. With engine idling, push the ENGINE START/STOP button on the steering wheel
to STOP the engine.

NOTE:

Do not leave the ignition in ACC mode when
the engine is off.
To shut off the engine with vehicle speed
greater than 5 mph (8 km/h), you must push
and hold the ignition or push the ENGINE
START/STOP button three times consecutively
within a few seconds. The engine will shut
down, and the ignition will be placed in the
ACC mode With the keyless ignition system, it is possible
to exit the vehicle taking the key fob with you,
without the engine switching off. The vehicle
will inform about the absence of the key on
board, when the doors are closed.
After the engine has stopped (cycling from the
ACC to the OFF position) the accessories are
still powered for about three minutes, or until
a door is opened.
When the ignition is in the OFF mode, the
window switches remain active for three
minutes. Opening a front door will cancel this
function.
After severe driving, idle the engine to allow
the temperature inside the engine compart
-
ment to cool before shutting off the engine.
Turbocharger Cool Down
It is recommended before switching the
vehicle off, to keep the engine idling for a few
minutes so that the turbocharger can be suit -
ably lubricated. This procedure is particularly
recommended after severe driving.
After a full load operation, keep the engine
idling for three to five minutes before
switching it off.
This time allows the lubricating oil and the
engine coolant to eliminate the excessive heat
from combustion chamber, bearings, inner
components and turbocharger.
WARNING!
Never pour fuel or other flammable liquid
into the throttle body air inlet opening in
an attempt to start the vehicle. This could
result in flash fire causing serious
personal injury.
Do not attempt to push or tow your vehicle
to get it started. Vehicles equipped with an
automatic transmission cannot be started
this way. Unburned fuel could enter the
catalytic converter and once the engine
has started, ignite and damage the
converter and vehicle.
If the vehicle has a discharged battery,
booster cables may be used to obtain a
start from a booster battery or the battery
in another vehicle. This type of start can
be dangerous if done improperly

REFUELING THE VEHICLE
Refueling The Vehicle
Before refueling, make sure that the fuel type
is correct.
Also, stop the engine before refueling.

NOTE:

An inefficient catalytic converter leads to
harmful exhaust emissions, thus contributing
to air pollution.
Refueling Capacity
To ensure that you fill the tank completely, top
off twice after the first click of the fuel nozzle.
Further top-off could cause faults in the fuel
feeding system.
Refueling Procedure
The fuel filler door is unlocked when the
central door locking system is unlocked. It is
automatically locked when the central locking
system is applied.
Opening The Fuel Filler Door
To refuel proceed as follows:
1. Open fuel filler door by pushing on thepoint shown by the arrow.
Fuel Door
2. Remove the fuel filler cap.
3. Insert the fuel nozzle fully into the filler pipe.
WARNING!
Drivers must be careful when backing up
even when using the Rear Back Up Camera.
Always check carefully behind your vehicle,
and be sure to check for pedestrians,
animals, other vehicles, obstructions, or
blind spots before backing up. You are
responsible for the safety of your
surroundings and must continue to pay
attention while backing up. Failure to do so
can result in serious injury or death.
CAUTION!
To avoid vehicle damage, Rear Back Up
Camera should only be used as a parking
aid. The Rear Back Up Camera is unable
to view every obstacle or object in your
drive path.
To avoid vehicle damage, the vehicle must
be driven slowly when using the Rear Back
Up Camera to be able to stop in time when
an obstacle is seen. It is recommended
that the driver look frequently over his/her
shoulder when using the Rear Back Up
Camera.
CAUTION!
Never introduce leaded fuel to the tank,
even in small amounts in an emergency, as
this would damage the catalytic converter
beyond repair.

clogged; use a needle to unblock them if
necessary.
Exhaust System
Adequate maintenance of the engine exhaust
system represents the best protection against
leaks of carbon monoxide into the passenger
compartment.
If an unusual noise from the exhaust or the
presence of smoke in the passenger compart
-
ment is identified, or if the underbody or rear
section of the vehicle have been damaged,
have the entire exhaust system and adjoining
bodywork areas checked at an authorized
dealer to identify any components which are
broken, damaged, worn or have moved from
their correct fitting position.
Open welding or loose connections may permit
exhaust gas to enter the passenger compart -
ment.
Have the exhaust system checked every time
the vehicle is raised. Replace the components
where necessary (for these operations,
contact an authorized dealer).
In normal operating conditions, the catalytic
converter does not require maintenance. To
ensure that it operates correctly, and prevent
it from getting damaged, it is extremely
important that the engine operates perfectly.
21_GU_OM_EN_USC_t.book Page 222

223

To minimize the risk of damaging the catalytic
converter, proceed as follows:
Do not stop the engine or deactivate the
ignition with gear engaged and vehicle in
motion.
Do not attempt to start the engine by bump
starting.
Do not use the vehicle if irregular idling or
operating conditions are experienced.
Cooling System
Coolant Check
Your vehicle has two cooling systems and both
need to be checked to ensure they are at
proper fill levels
Ú
page 214.
Check the engine coolant and intercooler
coolant level every oil change or before long
trips.
If there are impurities in the engine coolant,
the system must be drained, flushed and
refilled: contact an authorized dealer. Check the front part of the condenser for any
build-up of insects, leaves or other debris.
Should it be dirty, clean by spraying delicately
with water.
Check the hoses of the engine/intercooler
cooling system to ensure that the rubber has
not deteriorated and that there are no cracks,
tears, cuts or obstructions in the expansion
tank side and radiator side connectors. Should
there be any doubt regarding leaks from the
system (e.g. if frequent top ups are required),
have the seal checked at an authorized
dealer.
With the engine off and at normal operating
temperature, check that the cooling system
radiator cap is closed properly.

NOTE:

Before removing the coolant reservoir cap,
wait for the system to cool down.
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 eventually
poison you.
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.
WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam
coming from under the hood, do not open
the hood until the radiator has had time to
cool. Never open a cooling system pres
-
sure cap when the radiator or coolant
bottle is hot.
Keep hands, tools, clothing, and jewelry
away from the radiator cooling fan when
the hood is raised. The fan starts automat -
ically and may start at any time, whether
the engine is running or not.
When working near the radiator cooling
fan, disconnect the fan motor lead or turn
the ignition to the OFF mode. The fan is
temperature controlled and can start at
any time the ignition is in the ON mode. WARNING!
Do not open hot engine cooling system.
Never add engine coolant (antifreeze)
when the engine is overheated. Do not
loosen or remove the cap to cool an over -
heated engine. Heat causes pressure to
build up in the cooling system. To prevent
scalding or injury, do not remove the pres -
sure cap while the system is hot or under
pressure.
Do not use a pressure cap other than the
one specified for your vehicle. Personal
injury or engine damage may result.
