As the air bags deflate, you may see some
smoke-like particles. The particles are a
normal by-product of the process that
generates the non-toxic gas used for air
bag inflation. These airborne particles may
irritate the skin, eyes, nose, or throat. If
you have skin or eye irritation, rinse the
area with cool water. For nose or throat irri-
tation, move to fresh air. If the irritation
continues, see your doctor. If these parti -
cles settle on your clothing, follow the
garment manufacturer’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. 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 Occupant Restraint Controller
(ORC) will determine whether to have the
Enhanced Accident Response System
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

REFUELING THE VEHICLE
Fuel Filler Cap
The fuel filler cap is located on the
passenger'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.Fuel Filler Door Fuel Filler Cap
WARNING!
Never have any smoking materials lit in
or near the vehicle when the fuel door is
open or the tank is being filled.
Never add fuel when the engine is
running. This is in violation of most
countries regulations and may cause the
“Malfunction Indicator Light” to turn on.
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 a quarter
turn until you hear one click. This is an
indication that the cap is properly tight-
ened.
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.

CAUTION!
For diesel engines, only use diesel fuel for
motor vehicles in accordance with EN 590
European specifications. The use of other
products or mixtures may damage the
engine beyond repair and consequently
void the warranty, due to the damage
caused. If you accidentally introduce other
types of fuel into the tank, do not start the
engine. Empty the tank. If the engine has
been run for even an extremely limited
amount of time, you must not only drain
the fuel tank, but the rest of the supply
circuit as well.

3.6L Engine
This engine is designed to meet all emissions
regulations and provide excellent fuel
economy and performance when using
high-quality unleaded gasoline with a
minimum Research Octane Number (RON)
of 91.
Light spark knock at low engine speeds is not
harmful to your engine. However, continued
heavy spark knock at high speeds can cause
damage, and immediate service is required.
Poor quality gasoline can cause problems
such as hard starting, stalling, and hesita-
tions. If you experience these symptoms, try
another brand of gasoline before considering
service for the vehicle. 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 may help improve fuel
economy, reduce emissions, and maintain
vehicle performance.
Poor quality gasoline can cause problems
such as hard starting, stalling, and hesita
-
tions. If you experience these symptoms, try
another brand of gasoline before considering
service for the vehicle.
Materials Added To Fuel
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 Icon Identification Compliant To

FUEL REQUIREMENTS —
DIESEL ENGINE
Use good quality diesel fuel from a reputable
supplier. If the outside temperature is very
low, the diesel fuel thickens due to the
formation of paraffin clots with consequent
defective operation of the fuel supply
system.
In order to avoid these problems different
types of fuel are distributed according to the
season: summer type, winter type and arctic
type (cold/mountain areas). If fueling with
diesel fuel whose features are not suitable
for the temperature of use, it is advisable to
mix in a suitable additive with the fuel. With
the proportions shown on the container, pour
the additive in the tank before fueling.
When using or parking the vehicle for a long
time in the mountains or cold areas, it is
advisable to refuel using locally available
fuel. In this case, it is also advisable to keep
the tank over half full.
This vehicle must only use premium diesel
fuel that meets the requirements of EN 590.
Biodiesel blends up to 7% that meet EN
590 may also be used.Diesel fuel is seldom completely free of
water. To prevent fuel system trouble, drain
the accumulated water from the fuel/water
separator using the provided fuel/water
separator drain. If you buy good quality fuel
and follow the cold weather advice above,
fuel conditioners should not be required in
your vehicle. If available in your area, a high
cetane “premium” diesel fuel may offer
improved cold-starting and warm-up perfor
-
mance.

WARNING!
Do not use alcohol or gasoline as a
fuel-blending agent. They can be unstable
under certain conditions and hazardous or
explosive when mixed with diesel fuel.
CAUTION!
The manufacturer requires that you must
fuel this vehicle with Ultra Low Sulfur
Highway Diesel fuel (15 ppm Sulfur
maximum) and prohibits the use of Low
Sulfur Highway Diesel fuel.
