There may be areas inside your vehicle where the IA key is not detected.
If the message NO KEY DETECTED appears on your message center
when you press the START/STOP button, it may be necessary to move
your IA key to another area within the vehicle. The IA key may not be
detected near the roof (between the driver or passenger sunvisor and
the roof, or in the overhead console area) or in the extreme corners of
the rear package tray, near your audio speakers. It is not recommended
that you stow the IA key in these locations. If you move the IA key to a
location where it has been detected before and you still see the NO KEY
DETECTED message, your IA key’s battery may be low or you may be in
an area with excessive radio frequency interference. If this occurs, you
can use the backup method to start your vehicle (see below).
Backup Method of Starting:Your
IA key uses a radio frequency signal
to communicate with your vehicle
and authorize your vehicle to start
when you press the START/STOP
button and apply the brake pedal. If
excessive radio frequency
interference is present in the area,
or if the battery in your IA key is
low, it may be necessary to start
your car by inserting the IA key in
the backup slot, located in your glove box. Insert the IA key into the slot
with buttons facing out and with key ring up. After inserting the IA key

Press the parking brake pedal
downward again to release the
parking brake. Driving with the

ADVANCETRACSTABILITY ENHANCEMENT SYSTEM
WARNING:Vehicle modifications involving braking system,
aftermarket roof racks, suspension, steering system, tire
construction and/or wheel/tire size may change the handling
characteristics of the vehicle and may adversely affect the performance
of the AdvanceTracsystem. In addition, installing any stereo
loudspeakers may interfere with and adversely affect the AdvanceTrac
system. Install any aftermarket stereo loudspeaker as far as possible
from the front center console, the tunnel, and the front seats in order
to minimize the risk of interfering with the AdvanceTracsensors.
Reducing the effectiveness of the AdvanceTracsystem could lead to
an increased risk of loss of vehicle control, vehicle rollover, personal
injury and death.
WARNING:Remember that even advanced technology cannot
defy the laws of physics. It’s always possible to lose control of a
vehicle due to inappropriate driver input for the conditions. Aggressive
driving on any road condition can cause you to lose control of your
vehicle increasing the risk of personal injury or property damage.
Activation of the AdvanceTracsystem is an indication that at least
some of the tires have exceeded their ability to grip the road; this
could reduce the operator’s ability to control the vehicle potentially
resulting in a loss of vehicle control, vehicle rollover, personal injury
and death. If your AdvanceTracsystem activates, SLOW DOWN.

Note:If the system cannot be turned off in a MyKey™ equipped vehicle,
refer toMyKey™in theLocks and Securitychapter for more
information.
Note:If collision warnings are perceived as being too frequent or
disturbing then the warning sensitivity can be reduced, though the
manufacturer recommends using the highest sensitivity setting where
possible. Setting lower sensitivity would lead to fewer and later system
warnings. Refer to theMessage centerin theInstrument Cluster
chapter for instructions on reducing the sensitivity.
ACTIVE PARK ASSIST (APA) (IF EQUIPPED)
Active Park Assist (APA) will detect an available parallel parking space
and automatically steer the vehicle into the space (hands free) while you
control the accelerator, gearshift and brakes. The system will visually
and/or audibly instruct the driver to park the vehicle.
WARNING:This system is designed to be a supplementary park
aid. It is not intended to replace the driver’s attention and
judgment. The driver is responsible for avoiding hazards and
maintaining a safe distance and speed, even when the APA is in use.
Automatic Search for Parking Space
To start, press the APA control
switch (on the center console). The
message center will display ACTIVE
PARK SEARCHING. To designate
what side of the street to search on,
use the turn signal. The arrow
symbols >> and << in the message
center indicate on which side of the
vehicle APA will park. (If the turn
signal is not on, the system will
automatically search the passenger
side.)
