CAUTION!
life and/or prevent the engine from start-
ing.
• Accessories that draw higher power (i.e.,
coolers, vacuum cleaners, lights, etc.),
will degrade the battery even more
quickly. Only use these intermittently
and with greater caution.
• After the use of high power draw acces-
sories, or long periods of the vehicle not
being started (with accessories still
plugged in), the vehicle must be driven a
sufficient length of time to allow the
alternator to recharge the vehicle's bat-
tery.
• Power outlets are designed for accessory
plugs only. Do not hang any type of
accessory or accessory bracket from the
plug. Improper use of the power outlet
can cause damage.
Power Inverter — If Equipped
There is a 230 Volt, 150 Watt inverter outlet
located on the back of the center console to
convert DC current to AC current.
This outlet can power cellular phones, elec-
tronics and other low power devices requiring
power up to 150 Watts. Certain high-end
video game consoles exceed this power limit,
as will most power tools.The power inverter is designed with built-in
overload protection. If the power rating of
150 Watts is exceeded, the power inverter
automatically shuts down. Once the electri-
cal device has been removed from the outlet,
the inverter should automatically reset. If the
power rating exceeds approximately
170 Watts, the power inverter may have to be
reset manually.
WARNING!
To avoid serious injury or death:
• Do not insert any objects into the
receptacles.
• Do not touch with wet hands.
• Close the lid when not in use.
• If this outlet is mishandled, it may
cause an electric shock and failure.

• As the air bags deflate, you may see some
smoke-like particles. The particles are a
normal by-product of the process that gen-
erates the non-toxic gas used for air bag
inflation. These airborne particles may irri-
tate the skin, eyes, nose, or throat. If you
have skin or eye irritation, rinse the area
with cool water. For nose or throat irritation,
move to fresh air. If the irritation continues,
see your doctor. If these particles settle on
your clothing, follow the garment manufac-
turer’s instructions for cleaning.
Do not drive your vehicle after the air bags
have deployed. If you are involved in another
collision, the air bags will not be in place to
protect you.
WARNING!
Deployed air bags and seat belt preten-
sioners cannot protect you in another col-
lision. Have the air bags, seat belt preten-
sioners, and the seat belt retractor
assemblies replaced by an authorized
dealer immediately. Also, have the Occu-
pant Restraint Controller System serviced
as well.NOTE:
• Air bag covers may not be obvious in the
interior trim, but they will open during air
bag deployment.
• After any collision, the vehicle should be
taken to an authorized dealer immediately.
Enhanced Accident Response System
In the event of an impact, if the communica-
tion network remains intact, and the power
remains intact, depending on the nature of
the event, the ORC will determine whether to
have the Enhanced Accident Response Sys-
tem perform the following functions:
• Cut off fuel to the engine (If Equipped)
• Cut off battery power to the electric motor
(If Equipped)
• Flash hazard lights as long as the battery
has power
• Turn on the interior lights, which remain on
as long as the battery has power or for 15
minutes from the intervention of the En-
hanced Accident Response System.
• Unlock the power door locks.Your vehicle may also be designed to perform
any of these other functions in response to
the Enhanced Accident Response System:
• Turn off the Fuel Filter Heater, Turn off the
HVAC Blower Motor, Close the HVAC Circu-
lation Door
• Cut off battery power to the:
– Engine
– Electric Motor (if equipped)
– Electric power steering
– Brake booster
– Electric park brake
– Automatic transmission gear selector
– Horn
– Front wiper
– Headlamp washer pump
NOTE:
After an accident, remember to cycle the
ignition to the STOP (OFF/LOCK) position
and remove the key from the ignition switch
to avoid draining the battery. Carefully check
the vehicle for fuel leaks in the engine com-
partment and on the ground near the engine
compartment and fuel tank before resetting
the system and starting the engine. If there

Maintaining Your Air Bag System
WARNING!
• Modifications to any part of the air bag
system could cause it to fail when you
need it. You could be injured if the air
bag system is not there to protect you.
Do not modify the components or wiring,
including adding any kind of badges or
stickers to the steering wheel hub trim
WARNING!
cover or the upper passenger side of the
instrument panel. Do not modify the
front bumper, vehicle body structure, or
add aftermarket side steps or running
boards.
• It is dangerous to try to repair any part of
the air bag system yourself. Be sure to
tell anyone who works on your vehicle
that it has an air bag system.
• Do not attempt to modify any part of your
air bag system. The air bag may inflate
accidentally or may not function prop-
erly if modifications are made. Take your
vehicle to an authorized dealer for any
air bag system service. If your seat, in-
cluding your trim cover and cushion,
needs to be serviced in any way (includ-
ing removal or loosening/tightening of
seat attachment bolts), take the vehicle
to an authorized dealer. Only manufac-
turer approved seat accessories may be
used. If it is necessary to modify the air
bag system for persons with disabilities,
contact an authorized dealer.
Event Data Recorder (EDR)
This vehicle is equipped with an event data
recorder (EDR). The main purpose of an EDR
is to record, in certain crash or near crash-
like situations, such as an air bag deployment
or hitting a road obstacle, data that will assist
in understanding how a vehicle’s systems
performed. The EDR is designed to record
data related to vehicle dynamics and safety
systems for a short period of time, typically
30 seconds or less. The EDR in this vehicle is
designed to record such data as:
• How various systems in your vehicle were
operating;
• Whether or not the driver and passenger
safety belts were buckled/fastened;
• How far (if at all) the driver was depressing
the accelerator and/or brake pedal; and,
• How fast the vehicle was traveling.
These data can help provide a better under-
standing of the circumstances in which
crashes and injuries occur.

WARNING!
• 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
portable container that is inside of a
vehicle. You could be burned. Always
place fuel containers on the ground
while filling.
CAUTION!
• Damage to the fuel system or emission
control system could result from using
an improper fuel filler cap. A poorly
fitting cap could let impurities into the
fuel system. Also, a poorly fitting after-
market cap can cause the “Malfunction
Indicator Light (MIL)” to illuminate, due
to fuel vapors escaping from the system.
• To avoid fuel spillage and overfilling, do
not “top off” the fuel tank after filling.NOTE:
• When the fuel nozzle “clicks” or shuts off,
the fuel tank is full.
• Tighten the fuel filler cap about 1/4 turn
until you hear one click. This is an indica-
tion that the cap is properly tightened.
• If the fuel filler cap is not tightened prop-
erly, the MIL will come on. Be sure the cap
is tightened every time the vehicle is
refueled.
Loose Fuel Filler Cap Message
After fuel has been added, the vehicle diag-
nostic system can determine if the fuel filler
cap is possibly loose, improperly installed, or
damaged. If the system detects a malfunc-
tion, the “gASCAP” message will display in
the odometer display. Tighten the gas cap
until a "clicking" sound is heard. This is an
indication that the gas cap is properly tight-
ened. Push the odometer reset button to turn
the message off. If the problem persists, the
message will appear the next time the vehicle
is started. This might indicate a damagedcap. If the problem is detected twice in a row,
the system will turn on the MIL. Resolving the
problem will turn the MIL off.
REFUELING THE VEHICLE —
DIESEL
The fuel filler cap is located on the driver's
side of the vehicle. If the fuel filler cap is lost
or damaged, be sure the replacement cap is
the correct one for this vehicle.

To Reset The Manual Park Release:
1. Pull upward on the tether strap, releasing
it from the “locked” position.
2. Lower the Manual Park Release lever
downward and to the right, into its original
position.
3. Tuck the tether strap into the base of the
console, and reinstall the cover.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or
snow, it can often be moved using a rocking
motion. Turn the steering wheel right and left
to clear the area around the front wheels. For
vehicles with automatic transmission, push
and hold the lock button on the gear selector.
Then, shift back and forth between DRIVE
and REVERSE, while gently pressing the ac-
celerator. Use the least amount of accelerator
pedal pressure that will maintain the rocking
motion, without spinning the wheels or racing
the engine.NOTE:
• For vehicles with automatic transmission:
Shifts between DRIVE and REVERSE can
only be achieved at wheel speeds of 5 mph
(8 km/h) or less. Whenever the transmis-
sion remains in NEUTRAL for more than
2 seconds, you must press the brake pedal
to engage DRIVE or REVERSE.
• Push the "ESC Off" switch, to place the
Electronic Stability Control (ESC) system in
"Partial Off" mode, before rocking the ve-
hicle. Refer to “Electronic Brake Control
System” in “Safety” in your Owner’s
Manual for further details. Once the vehicle
has been freed, push the "ESC Off" switch
again to restore "ESC On" mode.
WARNING!
Fast spinning tires can be dangerous.
Forces generated by excessive wheel
speeds may cause damage, or even failure,
of the axle and tires. A tire could explode
and injure someone. Do not spin your ve-
hicle's wheels faster than 30 mph
(48 km/h) or for longer than 30 seconds
continuously without stopping when you
WARNING!
are stuck and do not let anyone near a
spinning wheel, no matter what the speed.
CAUTION!
• Racing the engine or spinning the
wheels may lead to transmission over-
heating and failure. Allow the engine to
idle with the transmission in NEUTRAL
for at least one minute after every five
rocking-motion cycles. This will mini-
mize overheating and reduce the risk of
clutch or transmission failure during
prolonged efforts to free a stuck vehicle.
• When “rocking” a stuck vehicle by shift-
ing between DRIVE/SECOND GEAR and
REVERSE, do not spin the wheels faster
than 15 mph (24 km/h), or drivetrain
damage may result.
• Revving the engine or spinning the
wheels too fast may lead to transmission
overheating and failure. It can also dam-
age the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear
(no transmission shifting occurring).
201

Your authorized dealer will reset the oil
change indicator message after completing
the scheduled oil change.
Once A Month Or Before A Long Trip
• Check the engine oil level about five min-
utes after a fully warmed engine is shut off.
Checking the oil level while the vehicle is
on level ground will improve the accuracy of
the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
• Check the windshield washer solvent and
add if required.
• Check tire pressure and look for unusual
wear or damage. Rotate tires at the first
sign of irregular wear, even if it occurs
before the oil indicator system turns on.• Inspect the battery and clean and tighten
the terminals as required.
• Check the fluid levels of coolant reservoir,
brake master cylinder and power steering
and fill as needed.
• Check all lights and other electrical items
for correct operation.
At Each Oil Change
• Change the engine oil filter.
• Inspect the brake hoses and lines.
CAUTION!
Failure to perform the required mainte-
nance items may result in damage to the
vehicle.Required Maintenance Intervals
Refer to the Maintenance Plan on the follow-
ing pages for the required maintenance inter-
vals.
Maintenance Plan
NOTE:
Once you have carried out the last interven-
tion in the table, continue with the scheduled
servicing, maintaining the frequency indi-
cated in the plan by marking each operation
with a dot or dedicated note. Simply restart-
ing the maintenance from the start of the
plan may cause the allowed interval to be
exceeded for some operations.

light is on. If necessary, add fluid to bring
level within the designated marks on the side
of the reservoir of the brake master cylinder.
Be sure to clean the top of the master cylin-
der area before removing cap. With disc
brakes, fluid level can be expected to fall as
the brake pads wear. Brake fluid level should
be checked when pads are replaced. If the
brake fluid is abnormally low, check the sys-
tem for leaks.
Refer to “Fluids And Lubricants” in “Techni-
cal Specifications” for further information.
WARNING!
• Brake fluid is poisonous and highly cor-
rosive. In the event of accidental con-
tact, immediately wash the affected
parts with water and neutral soap. Then
rinse thoroughly. Call a doctor immedi-
ately if swallowed.
• Use only manufacturer's recommended
brake fluid. Refer to “Fluids And Lubri-
cants” in “Technical Specifications” for
further information. Using the wrong
type of brake fluid can severely damage
WARNING!
your brake system and/or impair its per-
formance. The proper type of brake fluid
for your vehicle is also identified on the
original factory installed hydraulic mas-
ter 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 cylin-
der reservoir cap secured at all times.
Brake fluid in a 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 fail-
ure. This could result in a collision.
• Overfilling the brake fluid reservoir can
result in spilling brake fluid on hot en-
gine 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
WARNING!
components could be damaged, causing
partial or complete brake failure. This
could result in a collision.
Automatic Transmission
Fluid Level Check
The fluid level is preset at the factory and
does not require adjustment under normal
operating conditions. Routine fluid level
checks are not required; therefore the trans-
mission has no dipstick. An authorized dealer
can check your transmission fluid level using
special service tools. If you notice fluid leak-
age or transmission malfunction, visit an au-
thorized dealer immediately to have the
transmission fluid level checked. Operating
the vehicle with an improper fluid level can
cause severe transmission damage.
CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe
transmission damage may occur. An au-
