22 In Brief
Front Automatic Braking
(FAB) System If the vehicle has Forward Collision
Alert (FCA), it also has FAB, which
includes Intelligent Brake
Assist (IBA). When the system
detects a vehicle ahead in your path
that is traveling in the same
direction that you may be about to
crash into, it can provide a boost to
braking or automatically brake the
vehicle. This can help avoid or
lessen the severity of crashes when
driving in a forward gear.
See Front Automatic Braking (FAB)
System 0 240 .
Front Pedestrian Braking
(FPB) System If equipped, the FPB system may
help avoid or reduce the harm
caused by front-end crashes with
nearby pedestrians when driving in
a forward gear. FPB displays an
amber indicator,
~ , when a nearby
pedestrian is detected directly
ahead. When approaching a
detected pedestrian too quickly, FPB provides a red flashing alert on
the windshield and rapidly beeps or
pulses the driver seat. FPB can
provide a boost to braking or
automatically brake the vehicle.
See Front Pedestrian Braking (FPB)
System 0 241 .
Lane Keep Assist (LKA) If equipped, LKA may help avoid
crashes due to unintentional lane
departures. It may assist by gently
turning the steering wheel if the
vehicle approaches a detected lane
marking without using a turn signal
in that direction. It may also provide
a Lane Departure Warning (LDW)
alert as the lane marking is crossed.
The system will not assist or alert if
it detects that you are actively
steering. Override LKA by turning
the steering wheel. LKA uses a
camera to detect lane markings
between 60 km/h (37 mph) and
180 km/h (112 mph).
See Lane Departure Warning (LDW)
0 248 and Lane Keep Assist
(LKA) 0 248 . 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 moving
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. The Side Blind
Zone Alert (SBZA) system is
included as part of the LCA system.
See Side Blind Zone Alert (SBZA)
0 246 and Lane Change Alert
(LCA) 0 246 .
Surround Vision If equipped, views around the
vehicle display on the center stack
to aid with parking and low-speed
maneuvers.

Tire Pressure Monitor This vehicle may have a Tire
Pressure Monitor System (TPMS). The low tire pressure warning light
alerts to a significant loss in
pressure of one of the vehicle's
tires. If the warning light comes on,
stop as soon as possible and inflate
the tires to the recommended
pressure shown on the Tire and
Loading Information label. See
Vehicle Load Limits 0 198 . 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.
See Tire Pressure Monitor
System 0 308 . Engine Oil Life System The engine oil life system calculates
engine oil life based on vehicle use
and displays the CHANGE ENGINE
OIL SOON message when it is time

The oil life system should be reset
to 100% only following an oil
change.
