KEYS
Key Fobs
Your vehicle uses either a wireless ignition node system or
keyless ignition system. The ignition system consists of a
key fob with a Remote Keyless Entry (RKE) and an ignition
switch. The keyless ignition system consists of a key fob
and Keyless Enter-N-Go button.
NOTE:The key fob may not be found if it is located next to
a mobile phone, laptop or other electronic device; these
devices may block the key fob’s wireless signal.
The key fob operates the ignition switch. Insert the square
end of the key fob into the ignition switch located on the
instrument panel and rotate to the desired position. It also
contains the key fob and an emergency key, which stores in
the rear of the key fob.
The emergency key allows for entry into the vehicle should
the battery in the vehicle or the key fob go dead. You can
keep the emergency key with you when valet parking.
To remove the emergency key, slide the mechanical latch at
the top of the key fob sideways with your thumb and then
pull the key out with your other hand. NOTE:
When using the emergency key to gain access to
your vehicle, be aware that the security alarm may be
triggered. Insert the key into the ignition and place the
ignition in the ON/RUN mode to disarm the security
system.
This Keyless Push Button Ignition key fob allows the driver
to operate the ignition switch with the push of a button, as
long as the key fob is in the passenger compartment. The
Keyless Push Button Ignition has four operating positions,
three of which are labeled and will illuminate when in
position. The three positions are OFF, ACC, and ON/RUN.

40 GETTING TO KNOW YOUR VEHICLE

Onboard Diagnostic System (OBD II) Cybersecurity
Your vehicle is required to have an Onboard Diagnostic
system (OBD II) and a connection port to allow access to
information related to the performance of your emissions
controls. Authorized service technicians may need to ac-
cess this information to assist with the diagnosis and
service of your vehicle and emissions system.
WARNING!
•ONLY an authorized service technician should con-
nect equipment to the OBD II connection port in
order to diagnose or service your vehicle.
• If unauthorized equipment is connected to the OBD
II connection port, such as a driver-behavior tracking
device, it may:
• Be possible that vehicle systems, including safety
related systems, could be impaired or a loss of
vehicle control could occur that may result in an
accident involving serious injury or death.
• Access, or allow others to access, information
stored in your vehicle systems, including personal
information.
For further information, refer to “Cybersecurity” in “Mul-
timedia”.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass an
inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration. For states that require an Inspection and Mainte-
nance (I/M), this check verifies the “Malfunction
Indicator Light (MIL)” is functioning and is not on
when the engine is running, and that the OBD II system is
ready for testing.
Normally, the OBD II system will be ready. The OBD II
system may notbe ready if your vehicle was recently
serviced, recently had a dead battery or a battery replace-
ment. If the OBD II system should be determined not ready
for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition actuated test, which you
can use prior to going to the test station. To check if your
vehicle’s OBD II system is ready, you must do the follow-
ing:
1. Cycle the ignition switch to the ON position, but do not crank or start the engine.
NOTE: If you crank or start the engine, you will have to
start this test over.
