GETTING TO KNOW YOUR VEHICLE27
The Vehicle Security system is designed to
protect your vehicle. However, you can create
conditions where the system will give you a false
alarm. If one of the previously described arming
sequences has occurred, the Vehicle Security
system will arm regardless of whether you are in
the vehicle or not. If you remain in the vehicle
and open a door, the alarm will sound. If this
occurs, disarm the Vehicle Security system.
If the Vehicle Security system is armed and the
battery becomes disconnected, the Vehicle
Security system will remain armed when the
battery is reconnected; the exterior lights will
flash, and the horn will sound. If this occurs,
disarm the Vehicle Security system.
REARMING OF THE SYSTEM
If something triggers the alarm, and no action is
taken to disarm it, the Vehicle Security system
will turn the horn off after 29 seconds, five
seconds between cycles, and up to eight cycles
if the trigger remains active. The Vehicle
Security system will then rearm itself.
SECURITY SYSTEM MANUAL OVERRIDE
The Vehicle Security system will not arm if you
lock the doors using the manual door lock.
DOORS
MANUAL DOOR LOCKS
The power door locks can be manually locked
from inside the vehicle by using the door lock
knob. To lock each door, push the door lock
knob on each door trim panel downward. To
unlock the front doors, pull the inside door
handle to the first detent. To unlock the rear
doors, pull the door lock knob on the door trim
panel upward. If the lock knob is down when the
door is closed, the door will lock. Therefore,
make sure the key fob is not inside the vehicle
before closing the door.
NOTE:
Manually locking the vehicle will not arm the
Vehicle Security system.

Door Lock Knob

WARNING!
For personal security and safety in the
event of a collision, lock the vehicle doors
before you drive as well as when you park
and leave the vehicle.
When exiting the vehicle, always make sure
the keyless ignition is in the OFF mode,
remove the key fob from the vehicle and
lock your vehicle.
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 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 of 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.

Power Outlet Fuse Locations

When the vehicle is turned off, be sure to
unplug any equipment as to not drain the
battery of the vehicle. All accessories connected
to the outlet(s) should be removed or turned off
when the vehicle is not in use to protect the
battery against discharge.POWER INVERTER — IF EQUIPPED
A 115 Volt (400 Watts Maximum) inverter may
be located inside the center console towards
the right hand side. This inverter can power
cellular phones, electronics and other low
power devices requiring power up to 400 Watts.
Certain high-end video game consoles exceed
this power limit, as will most power tools.

WARNING!
To avoid serious injury or death:
Only devices designed for use in this type of
outlet should be inserted into any 12 Volt
outlet.
Do not touch with wet hands.
Close the lid when not in use and while
driving the vehicle.
If this outlet is mishandled, it may cause an
electric shock and failure.
CAUTION!
Many accessories that can be plugged in
draw power from the vehicle's battery, even
when not in use (i.e., cellular phones, etc.).
Eventually, if plugged in long enough, the
vehicle's battery will discharge sufficiently
to degrade battery life and/or prevent the
engine from starting.
Accessories that draw higher power (i.e.,
coolers, vacuum cleaners, lights, etc.), will
discharge the battery even more quickly.
Only use these intermittently and with
greater caution.
After the use of high power draw accesso -
ries, or long periods of the vehicle not being
started (with accessories still plugged in),
the vehicle must be driven a sufficient
length of time to allow the generator to
recharge the vehicle's battery.
CAUTION! (Continued)

ESCRIPTIONS — GASOLINE

1. Tachometer

Indicates the engine speed in revolutions
per minute (RPM x 1000).
2. Voltmeter
When the vehicle is in the RUN state, the
gauge indicates the electrical system
voltage. The pointer should stay within
the normal range if the battery is
charged. If the pointer moves to either
extreme left or right and remains there
during normal driving, the electrical
system should be serviced.
NOTE:
In vehicles equipped with Stop/Start, a reduced
voltage may be present during an Autostop.
3. Instrument Cluster Display
When the appropriate conditions exist,
this display shows the instrument cluster
display messages Ú page 114.
Instrument Cluster Display/Controls Location

The display always show one of the main
menu item after ignition on.
4. Oil Pressure Gauge
The pointer should always indicate the oil
pressure when the engine is running. A
continuous high or low reading under
normal driving conditions may indicate a
lubrication system malfunction. Imme -
diate service should be obtained from an
authorized dealer.
NOTE:
In vehicles equipped with Stop/Start, an oil
pressure indication of zero is normal during an
Autostop. 5. Speedometer
Indicates vehicle speed.
6. Fuel Gauge
The pointer shows the level of fuel in the
fuel tank when the ignition is in the ON/
RUN position.
 The fuel pump symbol points to the
side of the vehicle where the fuel door
is located.
7. Temperature Gauge
The pointer shows engine coolant
temperature. The pointer positioned
within the normal range indicates that
the engine cooling system is operating
satisfactorily.
The pointer will likely indicate a higher
temperature when driving in hot weather,
up mountain grades, or when towing a
trailer. It should not be allowed to exceed
the upper limits of the normal operating
range.

NOTE:
Your vehicle may be transmitting data
Ú page 482 as authorized by the subscriber.
Once a connection is made between the
vehicle’s SOS Call system and the SOS oper -
ator, the SOS operator may be able to open a
voice connection with the vehicle to deter -
mine if additional help is needed. Once the
SOS operator opens a voice connection with
the vehicle’s SOS Call system, the operator
should be able to speak with you or other
vehicle occupants and hear sounds occurring in the vehicle. The vehicle’s SOS Call system
will attempt to remain connected with the
SOS operator until the SOS operator termi
-
nates the connection.
5. The SOS operator may attempt to contact appropriate emergency responders and
provide them with important vehicle
information and GPS coordinates.
WARNING!
ALWAYS obey traffic laws and pay attention to
the road. ALWAYS drive safely with your hands
on the steering wheel. You have full
responsibility and assume all risks related to
the use of the features and applications in
this vehicle. Only use the features and
applications when it is safe to do so. Failure
to do so may result in an accident involving
serious injury or death.
WARNING!
If anyone in the vehicle could be in danger
(e.g., fire or smoke is visible, dangerous
road conditions or location), do not wait for
voice contact from an Emergency Services
Agent. All occupants should exit the vehicle
immediately and move to a safe location.
Never place anything on or near the
vehicle’s operable network and GPS
antennas. You could prevent operable
network and GPS signal reception, which
can prevent your vehicle from placing an
emergency call. An operable network and
GPS signal reception is required for the SOS
Call system to function properly.
The SOS Call system is embedded into the
vehicle’s electrical system. Do not add
aftermarket electrical equipment to the
vehicle’s electrical system. This may
prevent your vehicle from sending a signal
to initiate an emergency call. To avoid inter -
ference that can cause the SOS Call system
to fail, never add aftermarket equipment
(e.g., two-way mobile radio, CB radio, data
recorder, etc.) to your vehicle’s electrical
system or modify the antennas on your
vehicle. IF YOUR VEHICLE LOSES BATTERY
POWER FOR ANY REASON (INCLUDING
DURING OR AFTER AN ACCIDENT), THE
UCONNECT FEATURES, APPS AND
SERVICES, AMONG OTHERS, WILL NOT
OPERATE.
Modifications to any part of the SOS Call
system could cause the air bag system to
fail when you need it. You could be injured
if the air bag system is not there to help
protect you.
