GETTING TO KNOW YOUR INSTRUMENT PANEL113
 The fuel pump symbol points
to the side of the vehicle where
the fuel filler door is located.
Refer to “Refueling The Vehicle — Gas
Engine” in “Starting And Operating” for
further information.
5. Diesel Exhaust Fluid (DEF) Gauge
The DEF Gauge displays the actual level
of Diesel Exhaust Fluid in the DEF tank.
Diesel Exhaust Fluid (DEF) is required to
maintain normal vehicle operation and
emissions compliance. If something is
wrong with the gauge, a DEF Warning
Message or Malfunction Indicator Light
(MIL) will be displayed. More information
is available in the instrument cluster
display section under the heading of
Diesel Exhaust Fluid (DEF) Warning
Messages. NOTE:

The DEF tank on these vehicles is designed
with a large amount of full reserve. So the level
sensor will indicate a full reading even before
the tank is completely full. To put it another
way, there’s additional storage capacity in the
tank above the Full mark that’s not repre
-
sented in the gauge. You may not see any
movement in the reading – even after driving
up to 200 miles (322 kilometers) in some
cases.

The gauge may take up to five seconds to
update after adding a gallon or more of
Diesel Exhaust Fluid (DEF) to the DEF tank. If
you have a fault related to the DEF system,
the gauge may not update to the new level.
See an authorized dealer for service.
The DEF gauge may also not immediately
update after a refill if the temperature of the
DEF fluid is below 39°F (4°C). The DEF tank
heater will warm up the DEF fluid and allow
the gauge to update after a period of run
time. Under very cold conditions, it is possible
that the gauge may not reflect the new fill
level for several drives.
INSTRUMENT CLUSTER DISPLAY
Your vehicle will be equipped with an
instrument cluster display, which offers useful
information to the driver. With the ignition in the
OFF mode, opening/closing of a door will
activate the display for viewing, and display the
total miles, or kilometers, in the odometer. Your
instrument cluster display is designed to display
important information about your vehicle’s
systems and features. Using a driver interactive
display located on the instrument panel, your
instrument cluster display can show you how
systems are working and give you warnings
when they are not. The steering wheel mounted
controls allow you to scroll through the main
menus and submenus. You can access the
specific information you want and make
selections and adjustments.

STARTING AND OPERATING319

ENGINE RUNAWAY — DIESEL ENGINE
Diesel engine runaway is a rare condition
affecting diesel engines, where the engine
consumes its own lubrication oil and runs at
higher and higher RPM until it overspeeds to a
point where it destroys itself due to either
mechanical failure or engine seizure through
lack of lubrication.
REFUELING THE VEHICLE — GAS ENGINE
The fuel filler cap (gas cap) is located behind the
fuel filler door, on the left side of the vehicle.
Open the fuel door and remove the fuel filler cap
by turning it counter-clockwise.
Fuel Filler Cap

NOTE:
When removing the fuel filler cap, lay the cap
tether in the hook, located on the fuel filler door.
NOTE:
When the fuel nozzle “clicks” or shuts off, the
fuel tank is full.
WARNING!
In case of engine runaway due to flammable
fumes from fuel spills or turbocharger oil
leaks being sucked into the engine, do the
following to help avoid personal injury and/or
vehicle damage:
1. Turn the ignition switch to the OFF position.
2. Using a CO2 or dry chemical type fire
extinguisher, direct the spray from the fire
extinguisher into the grille on the driver side
so that the spray enters the engine air intake.
The inlet for the engine air intake is located
behind the drivers side headlamp and
receives air through the grille.
WARNING!
Never have any smoking materials lit in or
near the vehicle when the gas cap is
removed or the tank is being filled.
Never add fuel to the vehicle when the
engine is running.
A fire may result if gasoline is pumped into
a portable container that is inside of a
vehicle. You could be burned. Always place
gas containers on the ground while filling.
CAUTION!
Damage to the fuel system or emissions
control system could result from using an
improper fuel tank filler tube cap.
A poorly fitting fuel filler cap could let impu-
rities into the fuel system.
A poorly fitting fuel filler cap may cause the
“Malfunction Indicator Light (MIL)” to turn
on.
To avoid fuel spillage and overfilling, do not
“top off” the fuel tank after filling. When the
fuel nozzle “clicks” or shuts off, the fuel
tank is full.
WARNING! (Continued)

320STARTING AND OPERATING
Tighten the gas cap until you hear a “clicking”
sound. This is an indication that the gas cap
is tightened properly. The MIL in the instru -
ment cluster may turn on if the gas cap is not
secured properly. Make sure that the gas cap
is tightened each time the vehicle is refueled.
LOOSE FUEL FILLER CAP MESSAGE
If the vehicle diagnostic system
determines that the fuel filler cap is
loose, improperly installed, or
damaged, a loose gASCAP indicator
will display in the instrument cluster telltale
display area. Refer to “Instrument Cluster Display” in “Getting To Know Your Instrument
Panel” for further information. Tighten the fuel
filler cap properly and push the RIGHT button to
turn off the message. If the problem continues,
the message will appear the next time the
vehicle is started.
REFUELING THE VEHICLE — DIESEL ENGINE

1. Open the fuel filler door.

Fill Locations

NOTE:
There is no fuel filler cap. A flapper door inside
the filler pipe seals the system. 2. Insert the fuel nozzle fully into the filler pipe
– the nozzle opens and holds the flapper
door while refueling.
3. Fill the vehicle with fuel – when the fuel nozzle “clicks” or shuts off the fuel tank is
full.
4. Remove the fuel nozzle and close the fuel door.
Emergency Fuel Can Refueling
NOTE:
In the event that you run the vehicle out of fuel,
once refueled, place the ignition in the ON posi -
tion for 30 seconds, then turn the ignition OFF
and wait 30 seconds. Repeat this procedure
three times, prior to cranking the engine.
Most fuel cans will not open the flapper door.
A funnel is provided to open the flapper door to
allow emergency refueling with a fuel can.

1. Retrieve fuel funnel from the jack kit located under the front passenger seat.

2. Insert funnel into same filler pipe opening as the fuel nozzle.
WARNING!
Always place container on the ground
before filling.
Keep the pump nozzle in contact with the
container when you are filling it.
Use only approved containers for flam -
mable liquid.
Do not leave container unattended while
filling.
A static electric charge could cause a spark
and fire hazard.
