(Continued)
PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE OUTSIDE THE VEHICLE
Tires
Examine tires for excessive tread wear and uneven
wear patterns. Check for stones, nails, glass, or
other objects lodged in the tread or sidewall.
Inspect the tread for cuts and cracks. Inspect
sidewalls for cuts, cracks, and bulges. Check the
lug nut/bolt torque for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check the area under vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel or
brake fluid leaks are suspected, the cause should
be located and corrected immediately.
 ALWAYS REMOVE THE EXISTING
FLOOR MAT FROM THE VEHICLE before
installing any other floor mat. NEVER
install or stack an additional floor mat
on top of an existing floor mat.
ONLY install floor mats designed to fit your
vehicle. NEVER install a floor mat that cannot
be properly attached and secured to your
vehicle. If a floor mat needs to be replaced,
only use a FCA approved floor mat for the
specific make, model, and year of your
vehicle.
ONLY use the driver’s side floor mat on the
driver’s side floor area. To check for interfer -
ence, with the vehicle properly parked with the
engine off, fully press the accelerator, the
brake, and the clutch pedal (if present) to
check for interference. If your floor mat inter -
feres with the operation of any pedal, or is not
secure to the floor, remove the floor mat from
the vehicle and place the floor mat in your
trunk.
ONLY use the passenger’s side floor mat on
the passenger’s side floor area.
WARNING!
ALWAYS make sure objects cannot fall or slide
into the driver’s side floor area when the
vehicle is moving. Objects can become
trapped under accelerator, brake, or clutch
pedals and could cause a loss of vehicle
control.
NEVER place any objects under the floor mat
(e.g., towels, keys, etc.). These objects could
change the position of the floor mat and may
cause interference with the accelerator,
brake, or clutch pedals.
If the vehicle carpet has been removed and
re-installed, always properly attach carpet to
the floor and check the floor mat fasteners are
secure to the vehicle carpet. Fully press each
pedal to check for interference with the accel -
erator, brake, or clutch pedals then re-install
the floor mats.
It is recommended to only use mild soap and
water to clean your floor mats. After cleaning,
always check your floor mat has been properly
installed and is secured to your vehicle using
the floor mat fasteners by lightly pulling mat.

3. If using another vehicle to jump start the battery, park the vehicle within the jumper
cable’s reach, apply the parking brake and
make sure the ignition is OFF.
JUMP STARTING PROCEDURE
NOTE:Make sure at all times that unused ends of jumper
cables are not contacting each other or either
vehicle while making connections.
Connecting The Jumper Cables

1. Connect the positive
(+) end of the jumper
cable to the positive (+)
post of the discharged
vehicle.

2. Connect the opposite end of the positive (+)
jumper cable to the positive (+) post of the
booster battery. 3. Connect the negative
(-) end of the jumper
cable to the negative (-) post of the booster
battery.
4. Connect the opposite end of the negative (-)
jumper cable to a good engine ground. A
“ground” is an exposed metallic/unpainted
part of the engine, frame or chassis, such as
an accessory bracket or large bolt. The ground
must be away from the battery and the fuel
injection system.

Jump Starting Label

WARNING!
Do not allow vehicles to touch each other as
this could establish a ground connection and
personal injury could result.
Take care to avoid the radiator cooling fan
whenever the hood is raised. It can start
anytime the ignition switch is ON. You can be
injured by moving fan blades.
Remove any metal jewelry such as rings,
watch bands and bracelets that could make
an inadvertent electrical contact. You could be
seriously injured.
Batteries contain sulfuric acid that can burn
your skin or eyes and generate hydrogen gas
which is flammable and explosive. Keep open
flames or sparks away from the battery.
WARNING!
Failure to follow this jump starting procedure
could result in personal injury or property
damage due to battery explosion.
CAUTION!
Failure to follow these procedures could result in
damage to the charging system of the booster
vehicle or the discharged vehicle.
WARNING!
Do not connect the jumper cable to the negative
(-) post of the discharged battery. The resulting
electrical spark could cause the battery to
explode and could result in personal injury.

346IN CASE OF EMERGENCY
5. Start the engine in the vehicle that has the booster battery, let the engine idle a few
minutes, and then start the engine in the
vehicle with the discharged battery.
6. Once the engine is started, follow the discon -
necting procedure.
Disconnecting The Jumper Cables

1. Disconnect the negative
(-)
end of the jumper
cable from the engine ground of the vehicle
with the discharged battery.

2. Disconnect the opposite end of the negative (-)
jumper cable from the negative (-) post of the
booster battery. 3. Disconnect the positive
(+) end of the jumper
cable from the positive (+) post of the booster
battery.
4. Disconnect the opposite end of the positive (+)
jumper cable from the positive (+) post of the
discharged vehicle.
5. Reinstall the protective cover over the positive (+) post of the discharged vehicle.
If frequent jump starting is required to start your
vehicle you should have the battery and charging
system tested at an authorized dealer.
REFUELING IN EMERGENCY – IF EQUIPPED
The vehicle may be equipped with a refueling
funnel. Vehicles with diesel engines will have a cap
to remove to begin the refueling process. If
refueling is necessary, while using an approved
gas can, insert the refueling funnel into the filler
neck opening. Take care to open both flappers with
the funnel to avoid spills.

Diesel Fuel Cap

NOTE:In certain cold conditions, ice may prevent the fuel
door from opening. If this occurs, lightly push on
the fuel door to break the ice buildup and
re-release the fuel door using the inside release
button. Do not pry on the door.
CAUTION!
Do not run the booster vehicle engine above
2,000 RPM since it provides no charging benefit,
wastes fuel, and can damage booster vehicle
engine.
CAUTION!
Accessories plugged into the vehicle power
outlets draw power from the vehicle’s battery,
even when not in use (i.e., cellular devices, etc.).
Eventually, if plugged in long enough without
engine operation, the vehicle’s battery will
discharge sufficiently to degrade battery life
and/or prevent the engine from starting.

23_JT_OM_EN_USC_t.book Page 346

IN CASE OF EMERGENCY347
Emergency Gas Can Refueling
Most gas cans will not open the flapper doors. A
funnel is provided to allow emergency refueling
with a gas can.
See the following steps for refueling:

1. Retrieve funnel from under the right rear seat.

Fuel Funnel Location
Refueling Funnel
2. Remove the fuel filler cap and insert the funnel
into same filler pipe opening as the fuel nozzle.

Inserting Funnel

3. Ensure funnel is inserted fully to hold flapper doors open.
4. Pour fuel into funnel opening.
5. Remove funnel from filler pipe, clean off prior to putting back in the spare tire storage area.
6. Tighten the fuel filler cap until clicking is heard. This is an indication the cap is properly
tightened.
IF YOUR ENGINE OVERHEATS
If the vehicle is overheating, it will need to be
serviced by an authorized dealer.
Potential signs of vehicle overheating:
Temperature gauge is at HOT (H)
Strong smell of coolant
White smoke coming from engine or exhaust
Coolant bottle coolant has bubbles present
CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after 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 state and federal
fire regulations and may cause the Malfunc -
tion Indicator Light to turn on.
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.
