20 In Brief
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.
SeeFront Pedestrian Braking (FPB)
System 0211.
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)
0 215 andLane Keep Assist (LKA)
0 216.
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 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)
0 213 andLane Change Alert (LCA)
0 214.
Rear Vision
Camera (RVC)
RVC displays a view of the area
behind the vehicle on the
infotainment display when the
vehicle is shifted into R (Reverse) to
aid with parking and low-speed
backing maneuvers.
See Assistance Systems for Parking
or Backing 0204.
Rear Cross Traffic Alert
(RCTA) System
If equipped, the RCTA system uses
a triangle with an arrow displayed
on the infotainment display to warn
of traffic behind your vehicle that
may cross your vehicle's path while
in R (Reverse). In addition, beeps
will sound, or the driver seat will
pulse.
See Assistance Systems for Parking
or Backing 0204.
Parking Assist
If equipped, Rear Parking
Assist (RPA) 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). RPA may
display a warning triangle on the
infotainment display and a graphic
on the instrument cluster to provide
the object distance. In addition,
multiple beeps or seat pulses may
occur if very close to an object.
See Assistance Systems for Parking
or Backing 0204.

inspection and might require
several days of routine driving
before the system is ready for
inspection. This can happen if
the 12-volt battery has recently
been replaced or run down, or if
the vehicle has been recently
serviced.
See your dealer if the vehicle will
not pass or cannot be made ready
for the test.
Brake System Warning
Light
The vehicle brake system consists
of two hydraulic circuits. If one
circuit is not working, the remaining
circuit can still work to stop the
vehicle. For normal braking
performance, both circuits need to
be working.
If the warning light comes on, there
is a brake problem. Have the brake
system inspected right away.
MetricEnglish
This light should come on briefly
when the engine is started. If it does
not come on then, have it fixed so it
will be ready to warn you if there is
a problem.
If the light comes on and stays on,
there is a brake problem.
{Warning
The brake system might not be
working properly if the brake
system warning light is on.
Driving with the brake system
warning light on can lead to a
crash. If the light is still on after
the vehicle has been pulled off
the road and carefully stopped,
have the vehicle towed for
service.
Electric Parking Brake
Light
MetricEnglish
This light comes on when the
parking brake is applied. If the light
continues flashing after the parking
brake is released, or while driving,
there is a problem with the Electric
Parking Brake system. A message
may also display in the Driver
Information Center (DIC).
If the light does not come on,
or remains flashing, see your dealer.

when starting the vehicle. If it does
not come on, have it fixed so it will
be ready to warn if there is a
problem.
If this light stays on, take the vehicle
to your dealer as soon as possible.

Antilock Brake System
(ABS) Warning Light
This light comes on briefly when the
engine is started.
If the light does not come on, have it
fixed so it will be ready to warn if
there is a problem.
If the light comes on while driving,
stop as soon as it is safely possible
and turn off the vehicle. Then start
the engine again to reset the
system. If the ABS light stays on,
or comes on again while driving, the
vehicle needs service. A chime may
also sound when the light comes on
steady.
If the ABS light is the only light on,
the vehicle has regular brakes, but
the antilock brakes are not
functioning. If both the ABS and the brake
system warning light are on, the
vehicle's antilock brakes are not
functioning and there is a problem
with the regular brakes. See your
dealer for service.

systems and disable the airbags.
While driving, only shut the
vehicle off in an emergency.
If the ignition must be shut off in an
emergency: 1. Brake using a firm and steady pressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to N (Neutral). This can be done while the
vehicle is moving. After shifting
to N (Neutral), firmly apply the
brakes and steer the vehicle to
a safe location.
3. Come to a complete stop, shift to P (Park), and press ENGINE
START/STOP.
4. Set the parking brake. See Electric Parking Brake 0188. If the vehicle cannot be pulled over
and must be shut off while driving,
press and hold ENGINE START/
STOP for longer than two seconds,
or press twice in five seconds.
