2. Fit the new blade, inserting the tab in the dedicated housing in the arm and checking
that it is locked.
3. Lower the wiper arm onto the windshield.

NOTE:
Do not operate the windshield wiper with the
blades lifted from the windshield.
Windshield Washer
The window washer nozzles are fixed. If there is
no jet of fluid, first check that there is fluid in the
reservoir. Windshield Washers
Then, check that the nozzle holes are not
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
compartment 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
compartment.
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, however, and
prevent it from getting damaged, it is extremely
important that the engine operates perfectly.
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 persist in using the vehicle if idling is
very irregular or the operating conditions are
very notably irregular.
1 — Washer Nozzles
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.

ENGINE COOLING SYSTEM
Coolant Check
Your vehicle has two cooling systems and they
both need to be checked to ensure they are at
proper fill levels.
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
buildup of insects, leaves or other debris. Should
it be dirty, clean it 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.
Topping Up / Draining / Flushing The Engine/
Intercooler Coolant
If the engine coolant (antifreeze) is dirty, have
cleaning and flushing carried out at an authorized
dealer.
For the correct servicing intervals

Ú
page 182.

NOTE:

For topping up, use a fluid with the same
characteristics as those indicated on

Ú
page 233.
Do not use pure water, alcohol-based coolants,
corrosions inhibitors or additional anti-rust
products because they may be incompatible
with the engine coolant and cause the clogging
of the radiator. The use of propylene
glycol-based coolant is also not recommended.
Use care when filling under hood fluids such as
engine oil, windshield washer fluid, antifreeze
etc. to minimize spillage onto the top of the
engine. Any excess fluid that is spilled onto the
top of the engine should be removed using
compressed air or an absorbent cloth.
Engine Cooling/Intercooler System Cap
To prevent loss of engine coolant, make sure that
the expansion tank cap is closed. If it is open,
screw it completely until you reach/hear the click.
Periodically check the cap and clean it from any
foreign bodies that may have deposited on the
external surface.
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 pressure 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 automatically 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 position. The fan is
temperature controlled and can start at any
time the ignition is in the ON position.
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 overheated
engine. Heat causes pressure to build up in
the cooling system. To prevent scalding or
injury, do not remove the pressure 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.
WARNING!
Never add coolant with the engine hot or
overheated.
Do not attempt to cool an overheated engine
by loosening or removing the cap. The heat
causes a considerable increase in pressure
in the cooling system.
To prevent damage to the engine, only use
the engine cooling circuit caps provided.

Disposal Of Used Coolant
Disposal of engine/intercooler coolant is subject
to legal requirements: consult the appropriate
local regulations.

NOTE:

To prevent the fluid from being ingested by
children or animals, do not keep it in open
containers or pour it on the ground. If ingested,
contact a doctor immediately. Eliminate any
traces of fluid from the ground immediately.
When the vehicle stops after a short trip,
steam may be seen coming out from front of
the hood. This is a normal phenomenon which
is due to the presence of rain, snow or a lot of
moisture on the surface of the radiator.
With engine and system cold, do not top up
with coolant beyond the maximum level
indicated on the reservoir in the engine
compartment.
BRAKING SYSTEM
In order to guarantee the efficiency of the braking
system, periodically check its components; for
this operation, contact an authorized dealer.
For the correct servicing intervals

Ú
page 182.

NOTE:
Driving with your foot resting on the brake pedal
may compromise its efficiency, increasing the
risk of accidents. When driving, never keep your
foot on the brake pedal and don’t put unneces-
sary strain on it to prevent the brakes from over -
heating: excess pad wear may cause damage to
the braking system.
When an insufficient oil level is detected,
contact an authorized dealer to have the
system checked.
Always keep the cap of the brake fluid
reservoir (in the engine compartment)
completely closed.
AUTOMATIC TRANSMISSION
Use only a transmission oil with the same charac -
teristics as those indicated on
Ú
page 234.
Special Additives
Do not use any type of additive with the
automatic transmission oil. The automatic
transmission oil is a product designed especially
for this vehicle and its performance may be
compromised through the use of further
additives.
Frequency Of Oil Changes
In normal vehicle operating conditions, it is not
necessary to change the transmission oil.
REPLACING THE BATTERY
If necessary, replace the battery with another
battery with the same specifications. It is advised
to contact an authorized dealer for replacement.
WARNING!
Use only the manufacturer recommended
brake fluid
Ú
page 234. 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.
Do not allow petroleum-based fluid to
contaminate the brake fluid. Brake seal
components could be damaged, causing
partial or complete brake failure. This could
result in a collision.
CAUTION!
Do not use chemical flushes in your
transmission as the chemicals can damage
your transmission components. Such damage
is not covered by the New Vehicle Limited
Warranty.
CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe
transmission damage may occur. An
authorized dealer has the proper tools to
adjust the fluid level accurately.

Tire Pressures For High Speed Operation
The manufacturer advocates driving at safe
speeds and within posted speed limits. Where
speed limits or conditions are such that the
vehicle can be driven at high speeds, maintaining
correct tire inflation pressure is very important.
Increased tire pressure and reduced vehicle
loading may be required for high-speed vehicle
operation. Refer to an authorized tire dealer or
original equipment vehicle dealer for
recommended safe operating speeds, loading
and cold tire inflation pressures.Recommended Cold Tire Inflation Pressures
For vehicle speeds below 100 mph (160 km/h),
recommended cold tire inflation pressures are
listed on the Tire And Loading Information
Placard located on driver’s side B-pillar or the rear
edge of the driver's side door. When driving at speeds 100 mph (160 km/h)
and above, increased tire pressures and reduced
vehicle loading are required for high-speed
vehicle operation.
For driving speeds above 100 mph (160 km/h)
recommended cold tire inflation pressures are
listed in the following table under "High Speed
Tire Inflation Pressure". Vehicle loading condition
must not exceed 688 lb. (312kg) (driver + three
passengers + 88 lb. (40kg) luggage).
2.0L Engine
(*) All Season Tires, If Equipped
(**) Matching Rims/Tires
WARNING!

High speed driving with your vehicle under max -
imum load is dangerous. The added strain on
your tires could cause them to fail. You could
have a serious collision. Do not drive a vehicle
loaded to the maximum capacity at continuous
speeds above 75 mph (120 km/h).

Radial Ply Tires
Tire Repair
If your tire becomes damaged, it may be repaired
if it meets the following criteria:
The tire has not been driven on when flat.
The damage is only on the tread section of your
tire (sidewall damage is not repairable).
The puncture is no greater than a ¼ of an inch
(6 mm).
Consult an authorized tire dealer for tire repairs
and additional information. Damaged Run Flat tires, or Run Flat tires that
have experienced a loss of pressure should be
replaced immediately with another Run Flat tire
of identical size and service description (Load
Index and Speed Symbol). Replace the tire
pressure sensor as well as it is not designed to be
reused.
Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive
50 miles (80 km) at 50 mph (80 km/h) after a
rapid loss of inflation pressure. This rapid loss of
inflation is referred to as the Run Flat mode. A
Run Flat mode occurs when the tire inflation
pressure is of/or below 14 psi (96 kPa). Once a
Run Flat tire reaches the Run Flat mode it has
limited driving capabilities and needs to be
replaced immediately. A Run Flat tire is not
repairable. When a Run Flat tire is changed after
being driven under a Run Flat mode 14 psi
(96 kPa) condition, please replace the TPMS
sensor as it is not designed to be reused.

NOTE:
The TPMS sensor must be replaced after driving
the vehicle on a flat tire condition. It is not recommended driving a vehicle loaded at
full capacity or to tow a trailer while a tire is in the
Run Flat mode.

handle poorly. The instability could cause a
collision. Always use radial ply tires in sets of
four. Never combine them with other types of
tires.
WARNING!

Fast spinning tires can be dangerous. Forces
generated by excessive wheel speeds may
cause tire damage or failure. A tire could
explode and injure someone. Do not spin your
vehicle's wheels faster than 30 mph (48 km/h)
for more than 30 seconds continuously when
you are stuck, and do not let anyone near a
spinning wheel, no matter what the speed.

TIRE ROTATION RECOMMENDATIONS
Tires on the front and rear axles of vehicles
operate at different loads and perform different
steering, driving, and braking functions. For these
reasons, they wear at unequal rates. These
effects can be reduced by timely rotation of tires.
Rotation will increase tread life, maintain traction
levels and contribute to a smooth, quiet ride.
To resolve this problem, tires should be rotated at
each service interval (approximately every
10,000 miles [16,000km]). More frequent
rotation is permissible if desired. The reasons for
any rapid or unusual wear should be corrected
prior to rotation being performed.
Tire Rotations Not Recommended — If Equipped
Due to different size tires and wheels on front and
rear axles tire rotation is not possible for:
2.0T GME Engine Equipped with a 225/40R19
front and 255/35R19 rear tires
2.9L V6 Engine Equipped with 19” tires and
wheelsTire rotation contributes to the preservation of the
grip and traction performance on wet, muddy or
snowy roads, guaranteeing optimal drivability of
the vehicle.
In the case of irregular wear of the tires identify
the cause and correct it as soon as possible, by
contacting an authorized dealer.
Tire Rotation for Directional Tires — If Equipped
Directional tires are equipped on the following:
2.0T GME Engine equipped with same size
tires and wheels on front and rear axles
The rotational direction of the tire must be taken
into consideration when rotating the tires. The
recommended rotation pattern for directional
tires is shown in the following diagram.
Tire Rotation
All Wheel Drive (AWD) Models
It is recommended to avoid situations with a large
difference in wear between the front and rear
tires and to strictly use Winter tires of the sizes
given on the tire placard. The AWD system and the original tires are
developed together to ensure the vehicle’s best
performance. When changing the tires, it is
recommended to us the same “AR” marked tires,
to maintain the same level of performance and
component life.

UNIFORM TIRE QUALITY
GRADES
The following tire grading categories
were established by the National
Highway Traffic Safety Administration.
The specific grade rating assigned by
the tire's manufacturer in each
category is shown on the sidewall of the
tires on your vehicle.
All passenger vehicle tires must
conform to Federal safety requirements
in addition to these grades.
TREADWEAR
The Treadwear grade is a comparative
rating, based on the wear rate of the
tire when tested under controlled
conditions on a specified government
test course. For example, a tire graded
150 would wear one and one-half times
as well on the government course as a
tire graded 100. The relative
performance of tires depends upon the
