DRIVING AND OPERATING 209
{Warning
FAB is an emergency crash
preparation feature and is not
designed to avoid crashes. Do not
rely on FAB to brake the vehicle.
FAB will not brake outside of its
operating speed range and only
responds to detected vehicles.
FAB may not:. Detect a vehicle ahead on
winding or hilly roads.
. Detect all vehicles, especially
vehicles with a trailer,
tractors, muddy vehicles, etc.
. Detect a vehicle when
weather limits visibility, such
as in fog, rain, or snow.
. Detect a vehicle ahead if it is
partially blocked by
pedestrians or other objects.
Complete attention is always
required while driving, and you
should be ready to take action and
apply the brakes and/or steer the
vehicle to avoid crashes. FAB may slow the vehicle to a
complete stop to try to avoid a
potential crash. If this happens, FAB
may engage the Electric Parking Brake
(EPB) to hold the vehicle at a stop. To
release automatic braking, release the
EPB or firmly press the accelerator
pedal.
{Warning
FAB may automatically brake the
vehicle suddenly in situations
where it is unexpected and
undesired. It could respond to a
turning vehicle ahead, guardrails,
signs, and other non-moving
objects. To override FAB, firmly
press the accelerator pedal, if it is
safe to do so.
Intelligent Brake Assist (IBA)
IBA may activate when the brake
pedal is applied quickly by providing a
boost to braking based on the speed
of approach and distance to a vehicle
ahead.
Minor brake pedal pulsations or pedal
movement during this time is normal
and the brake pedal should continue
to be applied as needed. IBA will
automatically disengage only when
the brake pedal is released.
{Warning
IBA may increase vehicle braking in
situations when it may not be
necessary. You could block the flow
of traffic. If this occurs, take your
foot off the brake pedal and then
apply the brakes as needed.
FAB and IBA can be disabled through
vehicle personalization. See “Collision/
Detection Systems” underVehicle
Personalization 0144.
{Warning
Using FAB or IBA while towing a
trailer could cause you to lose
control of the vehicle and crash.
Turn the system to Off when
towing a trailer.

DRIVING AND OPERATING 211
When the System Does Not
Seem to Work Properly
SBZA displays may not come on when
passing a vehicle quickly, for a
stopped vehicle, or when towing a
trailer. The SBZA detection zones that
extend back from the side of the
vehicle do not move further back
when a trailer is towed. Use caution
while changing lanes when towing a
trailer. SBZA may alert to objects
attached to the vehicle, such as a
trailer, bicycle, or object extending out
to either side of the vehicle. This is
normal system operation; the vehicle
does not need service.
SBZA may not always alert the driver
to vehicles in the side blind zone,
especially in wet conditions. The
system does not need to be serviced.
The system may light up due to
guardrails, signs, trees, shrubs, and
other non-moving objects. This is
normal system operation; the vehicle
does not need service.
SBZA may not operate when the SBZA
sensors in the left or right corners of
the rear bumper are covered with
mud, dirt, snow, ice, or slush, or inheavy rainstorms. For cleaning
instructions, see "Washing the
Vehicle" under
Exterior Care0278.
If the DIC still displays the system
unavailable message after cleaning
both sides of the vehicle toward the
rear corners of the vehicle, see your
dealer.
If the SBZA displays do not light up
when vehicles are in the blind zone
and the system is clean, the system
may need service. Take the vehicle to
your dealer.
When SBZA is disabled for any reason
other than the driver turning it off,
the Side Blind Zone Alert On option
will not be available on the
personalization menu.
Lane Departure
Warning (LDW)
If equipped, LDW may help avoid
crashes due to unintentional lane
departures. It may provide an alert if
the vehicle is crossing a lane without
using a turn signal in that direction.
LDW uses a camera sensor to detect
the lane markings at speeds of 56
km/h (35 mph) or greater.
{Warning
The LDW system does not steer the
vehicle. The LDW system may not:
. Provide enough time to avoid
a crash.
. Detect lane markings under
poor weather or visibility
conditions. This can occur if
the windshield or headlamps
are blocked by dirt, snow,
or ice; if they are not in
proper condition; or if the sun
shines directly into the
camera.
. Detect road edges.
. Detect lanes on winding or
hilly roads.
If LDW only detects lane markings
on one side of the road, it will only
warn you when departing the lane
on the side where it has detected a
lane marking. Always keep your
attention on the road and maintain
proper vehicle position within the
lane, or vehicle damage, injury, (Continued)

Warning (Continued)
weather. Insert the refueling
nozzle slowly and wait for any
hiss noise to stop prior to
beginning to flow fuel.
If equipped, the fuel door is locked
when the vehicle doors are locked.
Press
Kon the RKE transmitter to
unlock. To open the fuel door, push
and release the rearward center edge
of the door. The vehicle has a capless refueling
system and does not have a fuel cap.
The filling nozzle must be fully
inserted and latched prior to starting
fuel flow.
{Warning
Overfilling the fuel tank by more
than three clicks of a standard fill
nozzle may cause:
. Vehicle performance issues,
including engine stalling and
damage to the fuel system.
. Fuel spills.
. Potential fuel fires.
Be careful not to spill fuel. Wait a few
seconds before removing the nozzle.
After initial shutoff, do not partially
remove the nozzle to add more fuel as
this will result in fuel spillage. Clean
fuel from painted surfaces as soon as
possible. See Exterior Care0278.
{Warning
If a fire starts while you are
refueling, do not remove the nozzle.
Shut off the flow of fuel by shutting
off the pump or by notifying the
station attendant. Leave the area
immediately.
Filling the Tank with a Portable
Gas Can
If the vehicle runs out of fuel and
must be filled from a portable gas can:
1. Locate the capless funnel adapter from under the carpet in
the trunk.
2. Insert and latch the funnel into the capless fuel system.

carbon monoxide (CO) from the
exhaust can get into the vehicle.
SeeEngine Exhaust 0182.
Safety Chains
Always attach chains between the
vehicle and the trailer. Cross the safety
chains under the tongue of the trailer
to help prevent the tongue from
contacting the road if it becomes
separated from the hitch. Leave
enough slack so the rig can turn.
Never allow safety chains to drag on
the ground.
Trailer Brakes
Does the trailer have its own brakes?
Be sure to read and follow the
instructions for the trailer brakes so
they are installed, adjusted, and
maintained properly.
Because the vehicle has antilock
brakes, do not tap into the vehicle's
brake system. If this is done, both
brake systems will not work well or
at all.
Conversions and
Add-Ons
Add-On Electrical
Equipment
{Warning
The Data Link Connector (DLC) is
used for vehicle service and
Emission Inspection/Maintenance
testing. See Malfunction Indicator
Lamp (Check Engine Light) 0120.
A device connected to the DLC —
such as an aftermarket fleet or
driver-behavior tracking device —
may interfere with vehicle systems.
This could affect vehicle operation
and cause a crash. Such devices
may also access information stored
in the vehicle’s systems.
Caution
Some electrical equipment can
damage the vehicle or cause
components to not work and would
not be covered by the vehicle
warranty. Always check with your
dealer before adding electrical
equipment.
Add-on equipment can drain the
vehicle's 12-volt battery, even if the
vehicle is not operating.
The vehicle has an airbag system.
Before attempting to add anything
electrical to the vehicle, see Servicing
the Airbag-Equipped Vehicle 079
and Adding Equipment to the
Airbag-Equipped Vehicle 079.
