Your vehicle may also be equipped with Dynamic Steering
Torque (DST), Hill Descent Control (HDC), Rain Brake
Support (RBS), Ready Alert Braking (RAB), Selec-Speed
Control (SSC), and Trailer Sway Control (TSC).
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sensing
the rate and amount of brake application and then applies
optimum pressure to the brakes. This can help reduce
braking distances. The BAS complements the Anti-Lock
Brake System (ABS). Applying the brakes very quickly
results in the best BAS assistance. To receive the benefit
of the system, you must apply continuous braking
pressure during the stopping sequence (do not “pump”
the brakes). Do not reduce brake pedal pressure unless
braking is no longer desired. Once the brake pedal is
released, the BAS is deactivated.
Brake System Warning Light
The red Brake System Warning Light will turn on when the
ignition is placed in the ON/RUN mode and may stay on for
as long as four seconds.
If the Brake System Warning Light remains on or comes on
while driving, it indicates that the brake system is not
functioning properly and that immediate service is
required. If the Brake System Warning Light does not
come on when the ignition is placed in the ON/RUN mode,
have the light repaired as soon as possible.
Dynamic Steering Torque (DST)
DST is a feature of the Electronic Stability Control (ESC)
and the Electric Power Steering (EPS) modules, that
provides torque at the steering wheel for certain driving
conditions, in which the ESC module is detecting vehicle
instability. The torque that the steering wheel receives is
only meant to help the driver realize optimal steering
behavior in order to reach/maintain vehicle stability. The
only notification the driver receives that the feature is
active is the torque applied to the steering wheel.
NOTE:The DST feature is only meant to help the driver realize the
correct course of action through small torques on the
steering wheel, which means the effectiveness of the DST
feature is highly dependent on the driver’s sensitivity and
overall reaction to the applied torque. It is very important
to realize that this feature will not steer the vehicle,
meaning the driver is still responsible for steering the
vehicle.
Electronic Brake Force Distribution (EBD)

EBD function manages the distribution of the braking
torque between the front and rear axles by limiting braking
pressure to the rear axle. This is done to prevent overslip of
the rear wheels to avoid vehicle instability, and to prevent
the rear axle from entering ABS before the front axle.

Electronic Roll Mitigation (ERM)
ERM anticipates the potential for wheel lift by monitoring
the driver’s steering wheel input and the speed of the
vehicle. When ERM determines that the rate of change of
the steering wheel angle and vehicle’s speed are
sufficient to potentially cause wheel lift, it then applies the
appropriate brake and may also reduce engine power to
lessen the chance that wheel lift will occur. ERM can only
reduce the chance of wheel lift occurring during severe or
evasive driving maneuvers; it cannot prevent wheel lift
due to other factors, such as road conditions, leaving the
roadway, or striking objects or other vehicles.
NOTE:ERM is disabled any time the ESC is in “Full Off” mode (if
equipped) Úpage 145.
WARNING!
The Brake Assist System (BAS) cannot prevent the natu -
ral laws of physics from acting on the vehicle, nor can it
increase the traction afforded by prevailing road condi -
tions. BAS cannot prevent collisions, including those
resulting from excessive speed in turns, driving on very
slippery surfaces, or hydroplaning. The capabilities of a
BAS-equipped vehicle must never be exploited in a
reckless or dangerous manner, which could jeopardize
the user's safety or the safety of others.
WARNING!

Many factors, such as vehicle loading, road conditions
and driving conditions, influence the chance that wheel
lift or rollover may occur. ERM cannot prevent all wheel
lift or rollovers, especially those that involve leaving the
roadway or striking objects or other vehicles. The capa -
bilities of an ERM-equipped vehicle must never be
exploited in a reckless or dangerous manner which could
jeopardize the user's safety or the safety of others.

Rear Monitoring

Overtaking Traffic
If you pass another vehicle slowly with a relative speed
less than 15 mph (24 km/h) and the vehicle remains in
the blind spot for approximately 1.5 seconds, the warning
light will be illuminated. If the difference in speed between
the two vehicles is greater than 15 mph (24 km/h), the
warning light will not illuminate.

Overtaking/Approaching
Overtaking/Passing

The BSM system is designed not to issue an alert on
stationary objects such as guardrails, posts, walls, foliage,
berms, etc. However, occasionally the system may alert on
such objects. This is normal operation and your vehicle
does not require service. The BSM system will not alert you of objects that are
traveling in the opposite direction of the vehicle in
adjacent lanes
Úpage 262.

Opposing Traffic

WARNING!
The Blind Spot Monitoring system is only an aid to help
detect objects in the blind spot zones. The BSM system
is not designed to detect pedestrians, bicyclists, or
animals. Even if your vehicle is equipped with the BSM
system, always check your vehicle’s mirrors, glance
over your shoulder, and use your turn signal before
changing lanes. Failure to do so can result in serious
injury or death.

SAFETY155
When FCW status is set to “Only Warning”, this
prevents the system from providing limited active
braking, or additional brake support if the driver is not
braking adequately in the event of a potential frontal
collision.
 When FCW status is set to “Warning and Braking”, this
allows the system to warn the driver of a possible colli -
sion with the vehicle in front using audible/visual warn -
ings and it applies autonomous braking.
 The system will retain the last setting selected by the
driver after ignition shutdown.
FCW Braking Status And Sensitivity

The FCW Sensitivity and Active Braking status are
programmable through the Uconnect system
Ú
page 126.

 Far
 When the sensitivity of FCW is set to the “Far”
setting and the system status is “Only Warning”,
this allows the system to warn the driver of a
possible more distant collision with the vehicle in
front using audible/visual warnings.
 More cautious drivers that do not mind frequent
warnings may prefer this setting.
NOTE:The “Far” setting may result in a greater number of FCW
possible collision warnings experienced.
Medium
 When the sensitivity of FCW is set to the “Medium”
setting and the system status is “Only Warning”,
this allows the system to warn the driver of a
possible collision with the vehicle in front using
audible/visual warnings. 
Near
 When the sensitivity of FCW is set to the “Near”
setting and the system status is “Only Warning”,
this allows the system to warn the driver of a
possible closer collision with the vehicle in front
using audible/visual warnings.
 This setting provides less reaction time than the
“Far” and “Medium” settings, which allows for a
more dynamic driving experience.
 More dynamic or aggressive drivers that want to
avoid frequent warnings may prefer this setting.
NOTE:The “Near” setting may result in a lesser number of FCW
possible collision warnings experienced.
FCW Limited Warning
If the instrument cluster display reads “ACC/FCW Limited
Functionality” or “ACC/FCW Limited Functionality Clean
Front Windshield” momentarily, there may be a condition
that limits FCW functionality. Although the vehicle is still
drivable under normal conditions, the active braking may
not be fully available. Once the condition that limited the
system performance is no longer present, the system will
return to its full performance state. If the problem persists,
see an authorized dealer.
Service FCW Warning
If the system turns off, and the instrument cluster display
reads:
ACC/FCW Unavailable Service Required
 Cruise/FCW Unavailable Service Required This indicates there is an internal system fault. Although
the vehicle is still driveable under normal conditions, have
the system checked by an authorized dealer.
TIRE PRESSURE MONITORING SYSTEM
(TPMS)
The TPMS will warn the driver of a low tire pressure based
on the vehicle recommended cold placard pressure.
The tire pressure will vary with temperature by
approximately 1 psi (7 kPa) for every 12°F (6.5°C). This
means that when the outside temperature decreases, the
tire pressure will decrease. Tire pressure should always be
set based on cold inflation tire pressure. This is defined as
the tire pressure after the vehicle has not been driven for
at least three hours, or driven less than 1 mile (1.6 km)
after a three hour period. The cold tire inflation pressure
must not exceed the maximum inflation pressure molded
into the tire sidewall. The tire pressure will also increase
as the vehicle is driven. This is normal and there should be
no adjustment for this increased pressure.
See
Úpage 235 on how to properly inflate the vehicle’s
tires.
The TPMS will warn the driver of a low tire pressure if the
tire pressure falls below the low-pressure warning limit for
any reason, including low temperature effects and natural
pressure loss through the tire.

SERVICE TPMS WARNING
When a system fault is detected, the TPMS Warning Light
will flash on and off for 75 seconds and then remain on
solid. The system fault will also sound a chime. In addition,
the instrument cluster will display a "SERVICE TPM
SYSTEM" message for a minimum of five seconds and
then display dashes (- -) in place of the pressure value to
indicate which sensor is not being received.

Tire Pressure Monitoring System Service Warning

If the ignition key is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault no
longer exists, the TPMS Warning Light will no longer flash,
and the “SERVICE TPM SYSTEM” message will no longer
display, and a pressure value will display in place of the
dashes. A system fault can occur due to any of the
following:
Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors.
 Installing some form of aftermarket window tinting that
affects radio wave signals. 
Lots of snow or ice around the wheels or wheel hous -
ings.
 Using tire chains on the vehicle.
 Using wheels/tires not equipped with TPMS sensors.
Vehicles With Compact Spare Or Non-Matching Full Size
Spare

1. The compact spare tire or non-matching full size does not have a TPMS sensor. Therefore, the TPMS
will not monitor the pressure in the compact spare
tire.

2. If you install the compact or non-matching full size spare tire in place of a road tire that has a pressure
below the low-pressure warning limit, upon the next
ignition key cycle, the TPMS Warning Light will remain
on and a chime will sound. In addition, the graphic in
the instrument cluster will still display a different
color pressure value and an "Inflate to XX" message.
3. After driving the vehicle for up to 20 minutes above 15 mph (24 km/h), the TPMS Warning Light will flash
on and off for 75 seconds and then remain on solid.
In addition, the instrument cluster will display a
“Service Tire Pressure System” message for five
seconds and then display dashes (- -) in place of the
pressure value.
4. For each subsequent ignition key cycle, a chime will sound, the TPMS Warning Light will flash on and off
for 75 seconds and then remain on solid, and the
instrument cluster will display a “SERVICE TPM
SYSTEM” message for five seconds and then display
dashes (- -) in place of the pressure value.
5. Once you repair or replace the original road tire and reinstall it on the vehicle in place of the compact spare or non-matching full size, the TPMS will update
automatically. In addition, the TPMS Warning Light
will turn off and the graphic in the instrument cluster
will display a new pressure value instead of dashes
(- -), as long as no tire pressure is below the
low-pressure warning limit in any of the four active
road tires. The vehicle may need to be driven for up to
20 minutes above 15 mph (24 km/h) in order for the
TPMS to receive this information.
TIRE PRESSURE MONITORING LOW PRESSURE
WARNINGS
The TPMS Warning Light will illuminate in the
instrument cluster and a chime will sound
when tire pressure is low in one or more of the
four active road tires. In addition, the
instrument cluster will display a "Tire Low" message for a
minimum of five seconds, an "Inflate to XX" message and
a graphic showing the pressure values of each tire with the
low tire pressure values in a different color.

Tire Pressure Monitoring System Low Pressure Warning

23_KL_OM_EN_USC_t.book Page 157

158SAFETY

Should this occur, you should stop as soon as possible and
inflate the tires with low pressure (those in a different color
in the instrument cluster graphic) to the vehicle’s
recommended cold placard pressure value as shown in the
"Inflate to XX" message. Once the system receives the
updated tire pressures, the system will automatically
update, the pressure values in the graphic display in the
instrument cluster will return to their original color, and the
TPMS Warning Light will turn off. The vehicle may need to
be driven for up to 20 minutes above 15 mph (24 km/h) in
order for the TPMS to receive this information.

NOTE:When filling warm tires, the tire pressure may need to be
increased up to an additional 4 psi (28 kPa) above the
recommended cold placard pressure in order to turn the
TPMS Warning Light off.
TIRE FILL ALERT
Tire Fill Alert notifies the user when the placard tire
pressure is attained while inflating or deflating the tire.
The customer may choose to disable or enable the Tire Fill
Alert feature through use of the customer settings in the
radio.
NOTE:
Only one tire can be filled at a time when using the Tire
Fill Alert system.
 The Tire Fill Alert feature cannot be entered if an
existing TPMS fault is set to “active” or if the system is
in deactivation mode (if equipped). The system will be activated when the system detects an
increase of tire pressure while inflating the tire. The
ignition must be in the RUN mode, with the transmission
in PARK (P).
NOTE:It is not required to have the engine running to enter Tire
Fill Alert mode.
The hazard lamps will come on to confirm the vehicle is in
Tire Fill Alert mode.
When Tire Fill Alert mode is entered, the tire pressure
display screen will be displayed in the instrument cluster.
Operation:

The horn will chirp once to let the user know when to
stop filling the tire, when it reaches recommended
pressure.
 The horn will chirp three times if the tire is over filled
and will continue to chirp every five seconds if the user
continues to inflate the tire.
 The horn will chirp once again when enough air is let
out to reach proper inflation level.
 The horn will also chirp three times if the tire is then
under-inflated and will continue to chirp every five
seconds if the user continues to deflate the tire.
 If the hazard lamps do not come on while inflating the
tire, the TPMS sensor may be in an inoperative posi -
tion, preventing the TPMS sensor signal from being
received. In this case, the vehicle may need to be
moved slightly forward or backward.
TPMS DEACTIVATION — IF EQUIPPED
The TPMS can be deactivated if replacing all four wheel
and tire assemblies (road tires) with wheel and tire
assemblies that do not have TPMS sensors, such as when
installing winter wheel and tire assemblies on your
vehicle.
To deactivate the TPMS, first replace all four wheel and
tire assemblies (road tires) with tires not equipped with
TPMS sensors. Then, drive the vehicle for 20 minutes
above 15 mph (24 km/h). The TPMS will chime, the TPMS
Warning Light will flash on and off for 75 seconds and then
remain on. The instrument cluster will display the
“SERVICE TPM SYSTEM” message and then display
dashes (--) in place of the pressure values.
Beginning with the next ignition cycle, the TPMS will no
longer chime or display the “SERVICE TPM SYSTEM”
message in the instrument cluster but dashes (--) will
remain in place of the pressure values.
To reactivate the TPMS, replace all four wheel and tire
assemblies (road tires) with tires equipped with TPMS
sensors. Then, drive the vehicle for up to 20 minutes
above 15 mph (24 km/h). The TPMS will chime, the TPMS
Warning Light will flash on and off for 75 seconds and then
turn off. The instrument cluster will display the “SERVICE
TPM SYSTEM” message and then display pressure values
in place of the dashes. On the next ignition cycle the
"SERVICE TPM SYSTEM" message will no longer be
displayed as long as no system fault exists.

OCCUPANT RESTRAINT SYSTEMS
Some of the most important safety features in your vehicle
are the restraint systems:
OCCUPANT RESTRAINT SYSTEMS
F
EATURES
 Seat Belt Systems
 Supplemental Restraint Systems (SRS) Air Bags
 Child Restraints
Some of the safety features described in this section may
be standard equipment on some models, or may be
optional equipment on others. If you are not sure, ask an
authorized dealer.
IMPORTANT SAFETY PRECAUTIONS
Please pay close attention to the information in this
section. It tells you how to use your restraint system
properly, to keep you and your passengers as safe as
possible.
Here are some simple steps you can take to minimize the
risk of harm from a deploying air bag:

1. Children 12 years old and under should always ride buckled up in the rear seat of a vehicle with a rear
seat.

2. A child who is not big enough to wear the vehicle seat belt properly must be secured in the appropriate child
restraint or belt-positioning booster seat in a rear
seating position
Úpage 176. 3. If a child from 2 to 12 years old (not in a rear-facing
child restraint) must ride in the front passenger seat,
move the seat as far back as possible and use the
proper child restraint
Úpage 176.
4. Never allow children to slide the shoulder belt behind them or under their arm.
5. You should read the instructions provided with your child restraint to make sure that you are using it
properly.
6. All occupants should always wear their lap and shoulder belts properly.
7. The driver and front passenger seats should be moved back as far as practical to allow the front air
bags room to inflate.
8. Do not lean against the door or window. If your vehicle has side air bags, and deployment occurs, the side air
bags will inflate forcefully into the space between
occupants and the door and occupants could be
injured.
9. If the air bag system in this vehicle needs to be modified to accommodate a disabled person, see
Úpage 258 for customer service contact
information.
SEAT BELT SYSTEMS
Buckle up even though you are an excellent driver, even
on short trips. Someone on the road may be a poor driver
and could cause a collision that includes you. This can
happen far away from home or on your own street.
Research has shown that seat belts save lives, and they
can reduce the seriousness of injuries in a collision. Some
of the worst injuries happen when people are thrown from
the vehicle. Seat belts reduce the possibility of ejection
and the risk of injury caused by striking the inside of the
vehicle. Everyone in a motor vehicle should be belted at all
times.
Enhanced Seat Belt Use Reminder System
(BeltAlert)
Driver And Passenger BeltAlert — If Equipped
BeltAlert is a feature intended to remind the
driver and outboard front seat passenger (if
equipped with outboard front passenger seat
BeltAlert) to buckle their seat belts. The
BeltAlert feature is active whenever the ignition switch is
in the START or ON/RUN position.WARNING!
 Never place a rear-facing child restraint in front of an
air bag. A deploying passenger front air bag can
cause death or serious injury to a child 12 years or
younger, including a child in a rear-facing child
restraint.
Never install a rear-facing child restraint in the front
seat of a vehicle. Only use a rear-facing child
restraint in the rear seat. If the vehicle does not have
a rear seat, do not transport a rear-facing child
restraint in that vehicle.

webbing necessary to comfortably wrap around the
occupant’s mid-section. Slide the latch plate into the
buckle until you hear a "click."
In Automatic Locking Mode, the shoulder belt is
automatically pre-locked. The seat belt will still retract to
remove any slack in the shoulder belt. Use the Automatic
Locking Mode anytime a child restraint is installed in a
seating position that has a seat belt with this feature.
Children 12 years old and under should always be properly
restrained in the rear seat of a vehicle with a rear seat.
How To Engage The Automatic Locking Mode

1. Buckle the combination lap and shoulder belt.

2. Grab the shoulder portion and pull downward until
the entire seat belt is extracted.
3. Allow the seat belt to retract. As the seat belt retracts, you will hear a clicking sound. This indicates the seat
belt is now in the Automatic Locking Mode. How To Disengage The Automatic Locking Mode
Unbuckle the combination lap/shoulder belt and allow it
to retract completely to disengage the Automatic Locking
Mode and activate the vehicle sensitive (emergency)
locking mode.
SUPPLEMENTAL RESTRAINT SYSTEMS

The ORC contains a backup power supply system that may
deploy the air bag system even if the battery loses power
or it becomes disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight seconds
for a self-check when the ignition switch is first in the ON/
RUN position. After the self-check, the Air Bag Warning
Light will turn off. If the ORC detects a malfunction in any
part of the system, it turns on the Air Bag Warning Light,
either momentarily or continuously. A single chime will
sound to alert you if the light comes on again after initial
startup.
The ORC also includes diagnostics that will illuminate the
instrument panel Air Bag Warning Light if a malfunction is
detected that could affect the air bag system. The
diagnostics also record the nature of the malfunction.
While the air bag system is designed to be maintenance
free, if any of the following occurs, have an authorized
dealer service the air bag system immediately.

The Air Bag Warning Light does not come on during the
four to eight seconds when the ignition switch is first in
the ON/RUN position.
 The Air Bag Warning Light remains on after the four to
eight-second interval.
 The Air Bag Warning Light comes on intermittently or
remains on while driving.
NOTE:If the speedometer, tachometer, or any engine related
