Air Bag Warning Light
The ORC monitors the readiness of the
electronic parts of the air bag system
whenever the ignition switch is in the
START or ON/RUN position. If the ignition
switch is in the OFF position or in the ACC
position, the air bag system is not on and
the air bags will not inflate.
The ORC contains a backup power supply
system that may deploy the air bag
system even if the battery loses power or
it becomes disconnected prior to
deployment.
The ORC turns on the Air Bag Warning
Light in the instrument panel for
approximately four to eight seconds for a
self-check when the ignition switch is
first in the ON/RUN position. After the
self-check, the Air Bag Warning Light will
turn off. If the ORC detects a malfunction
in any part of the system, it turns on the
Air Bag Warning Light, either
momentarily or continuously. A single
chime will sound to alert you if the light
comes on again after initial startup.
The ORC also includes diagnostics that
will illuminate the instrument panel Air
Bag Warning Light if a malfunction is
detected that could affect the air bag
system. The diagnostics also record the
nature of the malfunction. While the air
bag system is designed to be
maintenance free, if any of the followingoccurs, have an authorized dealer service
the air bag system immediately.
The Air Bag Warning Light does not
come on during the four to eight seconds
when the ignition switch is first in the
ON/RUN position.
The Air Bag Warning Light remains on
after the four to eight-second interval.
The Air Bag Warning Light comes on
intermittently or remains on while
driving.
Note: If the speedometer, tachometer,
or any engine related gauges are not
working, the Occupant Restraint
Controller (ORC) may also be disabled. In
this condition the air bags may not be
ready to inflate for your protection. Have
an authorized dealer service the air bag
system immediately.
Warning!
Ignoring the Air Bag Warning Light in your
instrument panel could mean you won’t have
the air bag system to protect you in a
collision. If the light does not come on as a
bulb check when the ignition is first turned
on, stays on after you start the vehicle, or if
it comes on as you drive, have an authorized
dealer service the air bag system
immediately.
Redundant Air Bag Warning Light
If a fault with the Air Bag Warning Light is
detected, which could affect the
Supplemental Restraint System (SRS),
the Redundant Air Bag Warning Light will
illuminate on the instrument panel. The
Redundant Air Bag Warning Light will
stay on until the fault is cleared. In
addition, a single chime will sound to alert
you that the Redundant Air Bag Warning
Light has come on and a fault has been
detected. If the Redundant Air Bag
Warning Light comes on intermittently or
remains on while driving have an
authorized dealer service the vehicle
immediately. For additional information
regarding the Redundant Air Bag Warning
Light refer to “Getting To Know Your
Instrument Panel” section of this manual.
Front Air Bags
This vehicle has front air bags and
lap/shoulder belts for both the driver and
front passenger. The front air bags are a
supplement to the seat belt restraint
systems. The driver front air bag is
mounted in the center of the steering
wheel. The passenger front air bag is
mounted in the instrument panel, above
the glove compartment. The words “SRS
AIRBAG” or “AIRBAG” are embossed on
the air bag covers.

SAFETY
Page 144 of 276
If you are required to drive with the
trunk/liftgate/rear doors open, make sure
that all windows are closed and the climate
control BLOWER switch is set at high speed.
DO NOT use the recirculation mode.
If it is necessary to sit in a parked vehicle
with the engine running, adjust your heating
or cooling controls to force outside air into
the vehicle. Set the blower at high speed.
The best protection against carbon
monoxide entry into the vehicle body is a
properly maintained engine exhaust
system.
Whenever a change is noticed in the
sound of the exhaust system, when
exhaust fumes can be detected inside the
vehicle, or when the underside or rear of
the vehicle is damaged, have a competent
mechanic inspect the complete exhaust
system and adjacent body areas for
broken, damaged, deteriorated, or
mispositioned parts. Open seams or
loose connections could permit exhaust
fumes to seep into the passenger
compartment. In addition, inspect the
exhaust system each time the vehicle is
raised for lubrication or oil change.
Replace as required.
Safety Checks You Should Make Inside
The Vehicle
Seat Belts
Inspect the seat belt system periodically,
checking for cuts, frays, and loose parts.
Damaged parts must be replaced
immediately. Do not disassemble or
modify the system.
Front seat belt assemblies must be
replaced after a collision. Rear seat belt
assemblies must be replaced after a
collision if they have been damaged (i.e.,
bent retractor, torn webbing, etc.). If
there is any question regarding seat belt
or retractor condition, replace the seat
belt.
Air Bag Warning Light
The Air Bag warning lightwill turn on
for four to eight seconds as a bulb check
when the ignition switch is first turned to
ON/RUN. If the light is either not on
during starting, stays on, or turns on while
driving, have the system inspected at
your authorized dealer as soon as
possible. After the bulb check, this light
will illuminate with a single chime when a
fault with the Air Bag System has been
detected. It will stay on until the fault is
removed. If the light comes on
intermittently or remains on while
driving, have your authorized dealer
service the vehicle immediately. Refer to
“Occupant Restraint Systems” in “Safety”
for further information.
Defroster
Check operation by selecting the defrost
mode and place the blower control on
high speed. You should be able to feel the
air directed against the windshield. See
your authorized dealer for service if your
defroster is inoperable.
Floor Mat Safety Information
Always use floor mats designed to fit
your vehicle. Only use a floor mat that
does not interfere with the operation of
the accelerator, brake or clutch pedals.
Only use a floor mat that is securely
attached using the floor mat fasteners so
it cannot slip out of position and interfere
with the accelerator, brake or clutch
pedals or impair safe operation of your
vehicle in other ways.

with access to an unlocked vehicle.
Allowing children to be in a vehicle
unattended is dangerous for a number of
reasons. A child or others could be seriously
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
children. 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. Refer to “Jump Starting” in “In Case Of Emergency”
for further information.
Caution!
To prevent damage to the starter, do not
continuously crank the engine for more than
25 seconds at a time. Wait 60 seconds
before trying again.
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 (if
equipped), 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.
How To Use Remote Start
All of the following conditions must be
met before the engine will remote start:
Gear selector in PARK (P).

The Windshield Wiper De-Icer timer and
operation will continue.
Cold Weather Operation
To prevent possible engine damage while
starting at low temperatures, this vehicle
will inhibit engine cranking when the
ambient temperature is less than –22° F
(–30° C) and the oil temperature sensor
reading indicates an engine block heater
has not been used. An externally-
powered electric engine block heater is
available as optional equipment or from
your authorized dealer.
The message “plug in engine heater” will
be displayed in the instrument cluster
when the ambient temperature is below
5° F (–15° C) at the time the engine is
shut off as a reminder to avoid possible
crank delays at the next cold start.
Caution!
Use of the recommended oil and adhering to
the prescribed oil change intervals is
important to prevent engine damage and
ensure satisfactory starting in cold

driven for at least 90 days, it is advisable
to follow the indications below. To start the engine, proceed as follows:
1. Briefly push the ignition button
2. If the engine does not start, wait five
seconds and let the starter cool down and
then repeat the starting procedure
3. If the engine does not start after eight
attempts, let the starter cool down for at
least 10 seconds, and then repeat the
starting procedure
If the problem persists, contact your
authorized dealer.
Note:
After prolonged vehicle inactivity,
very difficult starting, that can be noticed
through rapid fatigue of the starter,
might also be due to a partially flat
battery. In this case, refer to "Jump
Starting" in "In Case Of Emergency".
If Engine Fails To Start
Starting the Engine with Key Fob
Battery Run Down or Drained

25 seconds at a time. Wait 60 seconds
before trying again.
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
not dangerous for oncoming traffic.
2. Engage the PARK (P) mode.
3. With engine idling, push the
START/STOP button on the steering
wheel to STOP the engine.

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
START/STOP button three times
consecutively within a few seconds. The
engine will shut down, and the ignition will
be placed in the ON mode
With the keyless ignition system, it is
possible to go away from 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, only if the doors are closed.
Stopping the engine (cycling from the ON
to the STOP position) the accessories are
still powered for about three minutes, or
until a door is opened.
When the ignition is in the STOP/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
compartment 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 suitably 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.

instrument panel and the light on the
switch will turn off.
If the BRAKE warning light on the
instrument panel remains on with the
electric parking brake disengaged, this
indicates a fault: in this case, contact an
authorized dealer.
Warning!
Never leave children alone in a vehicle, or
with access to an unlocked vehicle.
Allowing children to be in a vehicle
unattended is dangerous for a number of
reasons. A child or others could be seriously
or fatally injured. Children should be warned
not to touch the park brake, brake pedal or
the gear selector.
150
STARTING AND OPERATING
Page 153 of 276
Do not leave the key fob in or near the
vehicle or in a location accessible to
children. A child could operate power
windows, other controls, or move the
vehicle.
Be sure the park brake is fully disengaged
before driving; failure to do so can lead to
brake failure and a collision.
Always fully apply the park brake when
leaving your vehicle, or it may roll and cause
damage or injury.
Note: Always engage the electric

AUTOMATIC TRANSMISSION
The vehicle can be equipped with an
electronically controlled 8-speed
automatic transmission where gear
shifting automatically takes place,
depending on the vehicle usage
instantaneous parameters (vehicle
speed, grade, and accelerator pedal
position).
The new transmission is an absolute
innovation, as it can match the
Stop/Start system with the traditional
automatic transmissions with built-in
torque converter. For further
information, refer to the “Stop/Start”
section within this chapter.
Manual gear shifting can still occur
thanks to the "Sequential" mode position
for the gear selector.
Warning!
It is dangerous to shift out of PARK or
NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly pressing
the brake pedal, the vehicle could
accelerate quickly forward or in reverse.
You could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and your
foot is firmly pressing the brake pedal.
Unintended movement of a vehicle could
injure those in or near the vehicle. As with all
vehicles, you should never exit a vehicle
while the engine is running. Before exiting a
vehicle, always apply the park brake, shift
the transmission into PARK, and turn the
ignition STOP/OFF. When the ignition is in
the STOP/OFF mode, the transmission is
locked in PARK, securing the vehicle against
unwanted movement.
When leaving the vehicle, always make
sure the ignition is in the STOP/OFF mode,
remove the key fob from the vehicle, and
lock the vehicle.
Never leave children alone in a vehicle, or
with access to an unlocked vehicle. Allowing
children to be in a vehicle unattended is
dangerous for a number of reasons. A child
or others could be seriously 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
children), and do not leave the ignition in the
AVV or ON mode. A child could operate
power windows, other controls, or move the
vehicle.
Caution!
Damage to the transmission may occur if
the following precautions are not observed:
Shift into or out of PARK or REVERSE
only after the vehicle has come to a
complete stop.
Do not shift between PARK, REVERSE,
NEUTRAL, or DRIVE when the engine is
above idle speed.
Before shifting into any gear, make sure
your foot is firmly pressing the brake pedal.
