Even if the SOS Call system is fully functional, factors
beyond FCA US LLC’s control may prevent or stop the SOS
Call system operation. These include, but are not limited to,
the following factors:
• Delayed accessories mode is active.
• The ignition is in the OFF position.
• The vehicle’s electrical systems are not intact.
• The SOS Call system software and/or hardware are
damaged during a crash. • The vehicle battery loses power or becomes disconnected
during a vehicle crash.
• LTE (voice/data) or 4G (data) network and/or Global
Positioning Satellite signals are unavailable or obstructed.
• Equipment malfunction at the SOS operator facility.
• Operator error by the SOS operator.
• LTE (voice/data) or 4G (data) network congestion.
• Weather.
• Buildings, structures, geographic terrain, or tunnels.WARNING!
• Ignoring the overhead console light could mean you
will not have SOS Call services. If the overhead console
light is illuminated, have your authorized dealer
service the SOS Call system immediately.
• The Occupant Restraint Control module turns on the
air bag Warning Light on the instrument panel if a
malfunction in any part of the system is detected. If the
Air Bag Warning Light is illuminated, have your autho -
rized dealer service the Occupant Restraint Control
system immediately.
WARNING!

3. Pull the bulb straight from it's socket and replace.
Removing The Bulb From The Bulb Socket FUSES
WARNING!
• When replacing a blown fuse, always use an appro -
priate replacement fuse with the same amp rating as the
original fuse. Never replace a fuse with another fuse of
higher amp rating. Never replace a blown fuse with
metal wires or any other material. Do not place a fuse
inside a circuit breaker cavity or vice versa. Failure to
use proper fuses may result in serious personal injury,
fire and/or property damage.
• Before replacing a fuse, make sure that the ignition is
off and that all the other services are switched off and/
or disengaged.
• If the replaced fuse blows again, contact an authorized
dealer.
• If a general protection fuse for safety systems (air bag
system, braking system), power unit systems (engine
system, transmission system) or steering system blows,
contact an authorized dealer.

SERVICING AND MAINTENANCE 411
Once A Month Or Before A Long Trip:
• Check engine oil level.
• Check windshield washer fluid level.
• Check the tire inflation pressures and look for unusual
wear or damage. Rotate at the first sign of irregular wear.
• Check the fluid levels of the coolant reservoir, brake
master cylinder, power steering and automatic transmis -
sion (six-speed only), and fill as needed.
• Check function of all interior and exterior lights. Maintenance Plan
Required Maintenance
Refer to the maintenance plan on the following pages for
required maintenance.
At Every Oil Change Interval As Indicated By Oil Change Indicator System:
• Change oil and filter.
• Rotate the tires. Rotate at the first sign of irregular wear, even if it occurs before the oil indicator system turns on.
• Inspect engine cooling system protection and hoses.
• Inspect exhaust system.
• Inspect engine air cleaner if using in dusty or off-road conditions.
• Inspect battery and clean and tighten terminals as required.
• Inspect automatic transmission fluid if equipped with dipstick.
• Inspect brake pads, shoes, rotors, drums, hoses and park brake.
• Inspect front end, and lubricate — If equipped with serviceable fittings. 7

BRAKE SYSTEM
If power assist is lost for any reason (for example, repeated
brake applications with the engine off), the brakes will still
function. However, you will experience a substantial
increase in braking effort to stop the vehicle.
If either the front or rear hydraulic system loses normal
braking capability, the remaining system will still function
with some loss of overall braking effectiveness. This will be
evident by increased pedal travel during application, greater
pedal force required to slow or stop, and activation of the
“Brake Warning Light” and the “ABS Warning Light” (if
equipped) during brake use.
The brake system power assist is provided by a hydro-boost
unit which shares fluid with the power steering system. You
may experience some clicking or hissing noises from the
hydro-boost system during hard braking conditions.
NOTE:
Under cold temperatures, pedal effort will be higher than
normal until the power steering fluid reaches operating
temperature. Hydraulic Brake Assist

WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure that
the wheel is properly mounted to the vehicle. Any time a
wheel has been removed and reinstalled on the vehicle, the
lug nuts/bolts should be torqued using a properly calibrated
torque wrench using a high quality six sided (hex) deep wall
socket.
