STARTING AND OPERATING

108

Activating Adaptive Cruise Control (ACC)
The minimum set speed for the ACC system is
19 mph (30 km/h) and the maximum is110 mph (180 km/h).
The system cannot be activated:
When pressing the brake pedal.
When the brakes are overheated.
When the Electric Park Brake has been
operated.
When either PARK, REVERSE or NEUTRAL is
engaged.
When the engine RPM is above a maximum
threshold.
When the vehicle speed is not within the
operational speed range.
When the Electronic Stability Control (ESC)
(or Anti-Lock Brake System (ABS) or other
stability control systems) are operating or
have just operated.
When the ESC system is off.
When the Forward Collision Warning system
(if equipped) is braking automatically.
In the event of a system failure.
When the engine is off.
In case of obstruction of the radar sensor (in
this case the bumper area where it is
located must be cleaned).
If the system is set, the conditions described
above also cause a cancellation or deactiva -
tion of the system. These situations may vary
according to the conditions.

NOTE:

The system will not be deactivated when
speeds higher than those set are reached by
pressing the accelerator pedal above
110 mph (180 km/h). In these situations, the system may not work correctly and it is recom -
mended to deactivate it.
To Activate/Deactivate
The system has four operating states:
Enabled (speed not set)
Activated (speed set)
Paused
Deactivated To Activate
To enable the system, push and release the
on/off button located on the left side on the
steering wheel.
On/Off Button
When the system is enabled and ready to
operate, the display shows the white ACC icon
above dashes in place of the speed.
Enabled Icons

Setting a speed activates the system. The
display shows the icon in green with the set
speed.

When entering a turn lane or highway off
ramp; when driving on roads that are
winding, icy, snow-covered, slippery, or
have steep uphill or downhill slopes.
When circumstances do not allow safe
driving at a constant speed.
WARNING! (Continued)

To Pause/Deactivate
With the feature enabled (speed not set), push
the on/off button to disable.
With the feature active (speed set), push the
on/off button to pause. The display will show
the icon in white with the speed in brackets. To
deactivate the feature, push the on/off button
a second time.
To Set A Desired Speed
When the vehicle reaches the desired speed,
push the RES/SET switch downward and
release it to activate the system. When the
accelerator is released, the vehicle will main-
tain the set speed automatically.
SET Switch While the accelerator pedal is pressed, the
system will not be able to control the distance
between the vehicle and the one ahead. In this
case, the speed will be determined only by the
position of the accelerator pedal.
The system will return to normal operation as
soon as the accelerator pedal is released.
To Vary The Speed Setting
To Increase Or Decrease The Set Speed
Once the system has been activated, you can
increase the speed by pushing the RES/SET
switch upward or decrease the speed by
pushing the RES/SET switch downward. Each
time the switch is pushed, the speed is
adjusted by 1 mph.
Pushing and holding the switch upward or
downward will cause the set speed to adjust in
5 mph increments until the button is released.
The new set speed is reflected in the instru
-
ment cluster display.

NOTE:

Moving the RES/SET switch downward
allows you to adjust the speed according to
the selected unit of measurement ("U.S." or
"Metric") set on the radio system. Refer to
the Information and Entertainment System
Owner’s Manual for more information.
When the unit of measurement is set to
Metric, pushing and holding the RES/SET switch will adjust the speed in 10 km/h
increments.
By keeping the accelerator pedal pressed,
the vehicle can continue to accelerate
beyond the set speed. In this case, use the
RES/SET switch to set the speed to the
vehicle’s current speed.
When you push the RES/SET button to
reduce the speed, the braking system inter
-
venes automatically if the engine brake
does not slow the vehicle down sufficiently
to reach the set speed. The device holds the
set speed uphill and downhill; however a
slight variation is entirely normal, particu -
larly on slight inclines.
The transmission could shift to a lower gear
when driving downhill, or when acceler -
ating. This is normal and necessary to main -
tain the set speed.
The system will disable while driving if the
brakes overheat.
To Resume

Once the system has been canceled but not
deactivated, to resume a previously set speed,
simply push the RES/SET switch upward and
remove your foot from the accelerator to recall it.

The system will be set to the last stored speed.
WARNING!

Leaving the Adaptive Cruise Control (ACC)
system on when not in use is dangerous. You
could accidentally set the system or cause it
to go faster than you want. You could lose
control and have a collision. Always leave the
system off when you are not using it.

IN CASE OF EMERGENCY

204

4. Disconnect the positive (+) end of thejumper cable from the positive (+) post of
the vehicle with the discharged battery.
If frequent jump starting is required to start
your vehicle, you should have the battery and
charging system inspected at an authorized
dealer.
Bump Starting
Never jump start the engine by pushing,
towing or coasting downhill.

NOTE:

You cannot start a vehicle with an automatic
transmission by pushing it.
ENGINE OVERHEATING
If your vehicle is overheating, it will need to be
serviced at an authorized dealer.
Engine overheating may occur in situations
such as (but not limited to) extreme environ -
mental temperatures or frequent engine
stops/starts. If the engine becomes over -heated, the Engine Temperature Warning
Light in the instrument cluster will illuminate
along with a dedicated message
Ú

page 79.
In any of the following situations, you can
reduce the potential for overheating by taking
the appropriate action.
On the highways — slow down.
In city traffic — while stopped, place the
transmission in NEUTRAL, but do not
increase engine idle speed.

NOTE:

There are steps that you can take to slow down
an impending overheat condition:
If your Air Conditioner (A/C) is on, turn it off.
The A/C system adds heat to the engine
cooling system and turning the A/C off can
help remove this heat.
You can also turn the temperature control
to maximum heat, the mode control to floor
and the blower control to high. This allows
the heater core to act as a supplement to
the radiator and aids in removing heat from
the engine cooling system.
NOTE:

If the cooling fan does not operate while the
engine is running, the engine temperature
will increase. Stop the engine and contact
an authorized dealer.
If the engine continues to overheat or
frequently overheats, have the cooling
system inspected. The engine could be seri
-
ously damaged unless repairs are made.
Contact an authorized dealer.
CAUTION!
Accessories plugged into the vehicle power
outlets draw power from the vehicle’s
battery, even when not in use (i.e., cellular
phones, etc.). Eventually, if plugged in long
enough without engine operation, the
vehicle’s battery will discharge sufficiently
to degrade battery life and/or prevent the
engine from starting.
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 try to open a cooling system
pressure cap when the radiator or coolant
bottle is hot.
CAUTION!
Driving with a hot cooling system could
damage your vehicle. If temperature gauge
reads “H”, pull over and stop the vehicle.
Idle the vehicle with the air conditioner
turned off until the pointer drops back into
the normal range. If the pointer remains on
the “H”, turn the engine off immediately,
and call for service.

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.

page 209.

NOTE:

For topping off, and proper coolant specifi -
cations
Ú
page 263.
Do not use pure water, alcohol-based cool -
ants, 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.
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. Disposal of Used Coolant
Disposal of engine/intercooler coolant is
subject to legal requirements. Contact the
appropriate body to determine local regula
-
tions.

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 the
front of the hood. This is a normal phenom -
enon 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 compo -
nents; for this operation, contact an autho -
rized dealer.

For the correct servicing intervals

Ú page 209.
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 unnecessary strain on it to prevent
the brakes from overheating. 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 reser-
voir (in the engine compartment)
completely closed.
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.
WARNING! (Continued)
WARNING!
Use only manufacturer's recommended
brake fluid
Ú
page 263. 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.

CNG And LP Fuel System Modifications
Modifications that allow the engine to run on
Compressed Natural Gas (CNG) or Liquid
Propane (LP) may result in damage to the
engine, emissions, and fuel system compo-
nents. Problems that result from running CNG
or LP are not the responsibility of the manufac -
turer and may void or not be covered under the
New Vehicle Limited Warranty.
MMT In Gasoline
Methylcyclopentadienyl Manganese Tricar -
bonyl (MMT) is a manganese-containing
metallic additive that is blended into some
gasoline to increase octane. Gasoline blended
with MMT provides no performance advantage
beyond gasoline of the same octane number
without MMT. Gasoline blended with MMT
reduces spark plug life and reduces emissions
system performance in some vehicles. The
manufacturer recommends that gasoline
without MMT be used in your vehicle. The MMT
content of gasoline may not be indicated on
the gasoline pump; therefore, you should ask
your gasoline retailer whether the gasoline
contains MMT. MMT is prohibited in Federal
and California reformulated gasoline.
Materials Added To Fuel
Besides using unleaded gasoline with the
proper octane rating, gasolines that contain
detergents, corrosion and stability additives
are recommended. Using gasolines that have these additives will help improve fuel
economy, reduce emissions, and maintain
vehicle performance.
Designated TOP TIER Detergent
Gasoline contains a higher level of
detergents to further aide in mini -
mizing engine and fuel system
deposits. When available, the usage of TOP
TIER Detergent Gasoline is recommended.
Visit
www.toptiergas.com
for a list of TOP TIER
Detergent Gasoline Retailers.
Indiscriminate use of fuel system cleaning
agents should be avoided. Many of these
materials intended for gum and varnish
removal may contain active solvents or similar
ingredients. These can harm fuel system
gasket and diaphragm materials.
Fuel System Cautions

NOTE:

Intentional tampering with the emissions
control system can result in civil penalties
being assessed against you.
CAUTION!
Follow these guidelines to maintain your
vehicle’s performance:
The use of leaded gasoline is prohibited by
Federal law. Using leaded gasoline can
impair engine performance and damage
the emissions control system.
An out-of-tune engine or certain fuel or
ignition malfunctions can cause the cata -
lytic converter to overheat. If you notice a
pungent burning odor or some light
smoke, your engine may be out of tune or
malfunctioning and may require imme -
diate service. Contact an authorized
dealer for service assistance.
The use of fuel additives, which are now
being sold as octane enhancers, is not
recommended. Most of these products
contain high concentrations of methanol.
Fuel system damage or vehicle perfor -
mance problems resulting from the use of
such fuels or additives is not the responsi -
bility of the manufacturer and may void or
not be covered under the New Vehicle
Limited Warranty.
CAUTION! (Continued)
