Lane Change Alert (LCA)
If equipped, the LCA system is a
lane-changing aid that assists
drivers with avoiding lane change
crashes that occur with vehicles in
the side blind zone (or spot) areas
or with vehicles rapidly approaching
these areas from behind. The LCA
warning display will light up in the
corresponding outside side mirror
and will flash if the turn signal is on.

If equipped, RVC displays a view of
the area behind the vehicle on the
center stack display when the
vehicle is shifted into R (Reverse).
See Assistance Systems for Parking
or Backing on page 9-47.
Ultrasonic Parking Assist
If equipped, Ultrasonic Rear Parking
Assist (URPA) uses sensors on the
rear bumper to assist with parking
and avoiding objects while in
R (Reverse). It operates at speeds
less than 8 km/h (5 mph). URPA
may display a warning triangle on
the Rear Vision Camera screen and
a graphic on the instrument cluster
to provide the object distance. In
addition, multiple beeps or pulses
may occur if very close to an object.
See Driver Assistance Systems on
page 9-47.
Active Emergency
Braking System
If the vehicle has Adaptive Cruise
Control (ACC) it also has the Active
Emergency Braking System, which
includes the Automatic Collision
Preparation (ACP) System. These
systems can automatically brake the
vehicle to help avoid or lessen the
severity of crashes.
See Active Emergency Braking
System on page 9-52.

Service
Never try to do your own service on
eAssist components. You can be
injured and the vehicle can be
damaged if you try to do your own

The warning light will remain on until
the tire pressure is corrected.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
may be an early indicator that the
tire pressures are getting low and
the tires need to be inflated to the
proper pressure.
The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.

Immobilizer Operation
(Key Access)
This vehicle has a passive
theft-deterrent system.
The system does not have to be
manually armed or disarmed.
The vehicle is automatically
immobilized when the key is
removed from the ignition. The system is automatically
disarmed when the vehicle is
started with the correct key. The key
uses a transponder that matches an
immobilizer control unit in the
vehicle and automatically disarms
the system. Only the correct key
starts the vehicle. The vehicle may
not start if the key is damaged.
The security light in the instrument
cluster comes on if there is a
problem with arming or disarming
the theft-deterrent system.
When trying to start the vehicle, the
security light comes on briefly when
the ignition is turned on.
If the engine does not start and the
security light stays on, there is a
problem with the system. Turn the
ignition off and try again.
