NOTE:TSC cannot stop all trailers from swaying. Always
use caution when towing a trailer and follow the
trailer tongue weight recommendations. See
Úpage 197 for further information.
When TSC is functioning, the ESC Activation/
Malfunction Indicator Light will flash, the engine
power may be reduced, and you may feel the
brakes being applied to individual wheels to
attempt to stop the trailer from swaying. TSC is
disabled when the ESC system is in the “Partial
Off” or “Full Off” modes.
AUXILIARY DRIVING SYSTEMS
BLIND SPOT MONITORING (BSM) —
I
F EQUIPPED
The BSM system uses two radar sensors, located
inside the taillights, to detect highway licensable
vehicles (automobiles, trucks, motorcycles, etc.)
that enter the blind spot zones from the rear/front/
side of the vehicle.
Rear Detection Zones

When the vehicle is started, the BSM Warning Light
will momentarily illuminate in both outside
rearview mirrors to let the driver know that the
system is operational. The BSM system sensors
operate when the vehicle is in any forward gear.
The BSM detection zone covers approximately one
lane width on both sides of the vehicle 12 ft
(3.8 m). The zone starts at the outside rearview
mirror and extends approximately 10 ft (3 m)
beyond the rear fascia/bumper of the vehicle. The
BSM system monitors the detection zones on both
sides of the vehicle when the vehicle speed
reaches approximately 6 mph (10 km/h) or higher
and will alert the driver of vehicles in these areas.
NOTE:
The BSM system DOES NOT alert the driver
about rapidly approaching vehicles that are
outside the detection zones.
The BSM system detection zone DOES NOT
change if your vehicle is towing a trailer. There -
fore, visually verify the adjacent lane is clear for
both your vehicle and trailer before making a
lane change. If the trailer or other object (i.e.,
bicycle, sports equipment) extends beyond the
side of your vehicle, this may result in the BSM
Warning Light remaining illuminated the entire
time the vehicle is in a forward gear. See
Ú page 215 for more information.
The Blind Spot Monitoring (BSM) system may
experience dropouts (blinking on and off) of the
side mirror warning indicator lights when a
motorcycle or any small object remains at the
side of the vehicle for extended periods of time
(more than a couple of seconds).
The BSM system can become blocked if snow, ice,
mud, or other road contaminations accumulate on
the rear fascia/bumper where the radar sensors
are located. The system may also detect a
blockage if the vehicle is operated in areas with
extremely low radar returns, such as a desert, or
parallel to a large elevation drop. If a blockage is
detected, a “Blind Spot Temporarily Unavailable,
Wipe Rear Corners” message will display in the
instrument cluster, both mirror lights will
illuminate, and BSM and RCP alerts will be
disabled. This is normal operation. The system will
automatically resume function when the condition
clears. To minimize system blockage, do not block
WARNING!
If TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and
adjust the trailer load to eliminate trailer sway.6

23_JT_OM_EN_USC_t.book Page 287

SAFETY299
Beginning with the next ignition cycle, the TPMS
will no longer chime or display the “SERVICE TIRE
PRESSURE 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 TIRE
PRESSURE SYSTEM” message and then display
pressure values in place of the dashes. On the next
ignition cycle the "SERVICE TIRE PRESSURE
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 Ú page 318.
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 Ú page 318.
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 428 for customer service contact
information.
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.

ALR — Switchable Automatic Locking Retractor

If the passenger seating position is equipped with
an ALR and is being used for normal usage, only
pull the seat belt webbing out far enough to
comfortably wrap around the occupant’s
mid-section so as to not activate the ALR. If the ALR
is activated, you will hear a clicking sound as the
seat belt retracts. Allow the webbing to retract
completely in this case and then carefully pull out
only the amount of 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.
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.
WARNING!
The seat belt assembly must be replaced if the
switchable Automatic Locking Retractor (ALR)
feature or any other seat belt function is not
working properly when checked according to
the procedures in the Service Manual.
Failure to replace the seat belt assembly
could increase the risk of injury in collisions.
Do not use the Automatic Locking Mode to
restrain occupants who are wearing the seat
belt or children who are using booster seats.
The locked mode is only used to install
rear-facing or forward-facing child restraints
that have a harness for restraining the child.6
