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
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.

Emergency Gas Can Refueling
Most gas cans will not open the flapper door.
A funnel is provided to open the flapper door
to allow emergency refueling with a gas can.
1. Retrieve funnel from the spare tirestorage area.
2. Insert funnel into same filler pipe opening as the fuel nozzle.
3. Ensure funnel is inserted fully to hold flapper door open.
4. Pour fuel into funnel opening.
Fuel Funnel
5. Remove the funnel from filler pipe, clean off prior to putting back in the spare tire
storage area.REFUELING THE VEHICLE —
DIESEL ENGINE
The Capless Fuel System uses a flapper
placed at the filler pipe of the fuel tank; it
opens and closes automatically upon inser -
tion/extraction of the fuel nozzle. The
Capless Fuel System is designed so that it
prevents the filling of an incorrect type of
fuel.
1. Unlock the fuel filler door by pushing the unlock button on the key fob or the
unlock button on the driver-side door
trim panel.
2. Open the fuel filler door by pushing on the rear edge of the Fuel Door.
3. There is no fuel filler cap. A flapper door inside the pipe seals the system.
4. Insert the fuel nozzle fully into the filler pipe; the nozzle opens and holds the
flapper door while refueling.
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.

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

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!
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.

FUEL REQUIREMENTS —
GASOLINE ENGINES
2.0L Engine
This engine is designed to meet all emission
regulations, and provide satisfactory fuel
economy and performance when using
high-quality unleaded gasoline with a recom-
mended RON of 95.
While operating on gasoline with the
required octane number, hearing a light
knocking sound from the engine is not a
cause for concern. However, if the engine is
heard making a heavy knocking sound, see
your dealer immediately. Use of gasoline
with a lower than recommended octane
number can cause engine failure and may
void or not be covered by the New Vehicle
Limited Warranty.
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.
2.4L And 3.2L Engines
These engine are designed to meet all emis -
sions regulations and provide excellent fuel
economy and performance when using high
quality unleaded gasoline with a minimum
research octane rating (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.
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
EN16942
The following symbols make it easier to
recognize the correct type of fuel to be used
on your vehicle. Before proceeding with the
supply, check the symbols placed inside the
fuel filler flap (if present) and compare them
with the symbol on the fuel pump (if
present).

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.
Fuel Icon Identification Compliant To
EN16942
The following symbols make it easier to
recognize the correct type of fuel to be used
on your vehicle. Before proceeding with the
supply, check the symbols placed inside the
fuel filler flap (if present) and compare them
with the symbol on the fuel pump (if
present).
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.
