STARTING AND OPERATING241

(Continued)
The following indicators should be used to
ensure that you have properly engaged the
transmission into the PARK position:
When shifting into PARK, pull the gear
selector toward you and move it all the way
counterclockwise until it stops.
Release the gear selector and make sure it is
fully seated in the PARK gate.
Look at the transmission gear position
display and verify that it indicates the PARK
position (P).
With brake pedal released, verify that the
gear selector will not move out of PARK.
REVERSE (R)
This range is for moving the vehicle backward.
Shift into REVERSE only after the vehicle has
come to a complete stop.
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 accel -
erate 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 come to a complete stop,
then apply the parking brake, shift the
transmission into PARK, turn the engine off,
and remove the key fob. When the ignition
is in the LOCK/OFF (key removal) position
(or, with Keyless Enter-N-Go, when the igni -
tion is in the 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 OFF mode,
remove the key fob from the vehicle, and
lock the vehicle.
WARNING! (Continued)
Never leave children alone in a vehicle, or
with access to an unlocked vehicle.
Allowing children to be in a vehicle unat -
tended 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 chil -
dren), and do not leave the ignition (in a
vehicle equipped with Keyless Enter-N-Go)
in the ACC or ON/RUN mode. A child could
operate power windows, other controls, or
move the vehicle.
CAUTION!
Before moving the transmission gear
selector out of PARK, you must turn the igni -
tion to the ON/RUN mode, and also press
the brake pedal. Otherwise, damage to the
gear selector could result.
WARNING! (Continued)
DO NOT race the engine when shifting from
PARK or NEUTRAL into another gear range,
as this can damage the drivetrain.
CAUTION! (Continued)

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.

JACKING AND TIRE CHANGING NOTE:
If your vehicle is equipped with an air suspen -
sion system, there is a feature which allows the
automatic leveling to be disabled to assist with
changing a tire.
This feature can be activated through the Ucon -
nect system.
Refer to “Uconnect Settings” in “Multimedia”
for further information.
JACK LOCATION
The jack and tools are stored under the front
passenger seat.
REMOVAL OF JACK AND TOOLS
To access the jack and jack tools, you must
remove the plastic access cover located on the
side of the front passenger’s seat. To remove
the cover, pull the front part of the cover
(closest to the front of the seat) toward you to
release a locking tab. Once the front of the
cover is loose, slide the cover toward the front
of the seat until it is free from the seat frame.
Jack Access Cover

Remove the jack and tools by turning the wing
bolt counterclockwise, remove the wing bolt
and then slide the assembly out from under the
seat.

Wing Bolt/Jack And Tools

WARNING!
Do not attempt to change a tire on the side
of the vehicle close to moving traffic. Pull
far enough off the road to avoid the danger
of being hit when operating the jack or
changing the wheel.
Being under a jacked-up vehicle is
dangerous. The vehicle could slip off the
jack and fall on you. You could be crushed.
Never put any part of your body under a
vehicle that is on a jack. If you need to get
under a raised vehicle, take it to a service
center where it can be raised on a lift.
Never start or run the engine while the
vehicle is on a jack.
The jack is designed to be used as a tool for
changing tires only. The jack should not be
used to lift the vehicle for service purposes.
The vehicle should be jacked on a firm level
surface only. Avoid ice or slippery areas.
