•Seatbelt warning light and chime.
•Crash sensors and monitoring systemwith readiness indicator.
The seatbelt pretensioners and rearinflatable seatbelts are designed to activatein frontal, near-frontal and side crashes, andin rollovers. The seatbelt pretensioners atthe front seating positions are designed totighten the seatbelts firmly against the
occupant’s body when activated. This helpsincrease the effectiveness of the seatbelts.In frontal crashes, the seatbelt pretensionerscan be activated alone or, if the crash is ofsufficient severity, together with the frontairbags.

Seatbelt Locking Modes
WARNING: If your vehicle is involvedin a crash, have the seatbelts andassociated components inspected as soonas possible. Failure to follow this instructioncould result in personal injury or death.
All safety restraints in the vehicle arecombination lap and shoulder belts. Thedriver seatbelt has the vehicle sensitivelocking mode. The front outboard passengerand rear seatbelts have both the vehiclesensitive locking mode and the automaticlocking mode.
Vehicle Sensitive Mode
This is the normal retractor mode, whichallows free shoulder belt length adjustmentto your movements and locking in responseto vehicle movement. For example, if thedriver brakes suddenly or turns a cornersharply, or the vehicle receives an impact ofabout 5 mph (8 km/h) or more, thecombination seatbelts lock to help reduceforward movement of the driver andpassengers.
In addition, the retractor is designed to lockif you pull the webbing out too quickly. If theseatbelt retractor locks, slowly lower theheight adjuster to allow the seatbelt toretract. If the retractor does not unlock, pullthe seatbelt out slowly then feed a small

length of webbing back toward the stowedposition. For rear seatbelts, recline the rearseat backrest or push the seat backrestcushion away from the seatbelt. Feed a smalllength of webbing back toward the stowedposition.
Automatic Locking Mode
In this mode, the shoulder belt automaticallypre-locks. The belt still retracts to removeany slack in the shoulder belt. The automaticlocking mode is not available on the driverseatbelt.
When to Use the Automatic Locking Mode
Use this mode when you install a child safetyseat, except a booster, in the passenger frontor rear seating positions. Properly restrainchildren 12 years old and under in a rearseating position whenever possible. SeeSeatbelts (page 39).

How to Disengage the Automatic LockingMode
Unbuckle the combination lap and shoulderbelt and allow it to retract completely todisengage the automatic locking mode andactivate the vehicle sensitive (emergency)locking mode.
Rear Inflatable Seatbelt (If Equipped)
WARNING: Do not attempt to service,repair, or modify the supplementaryrestraint system or associated components.Failure to follow this instruction could resultin personal injury or death.
The rear inflatable seatbelts are in theshoulder portion of the seatbelts of thesecond-row outermost seating positions.
Note:The rear inflatable seatbelts arecompatible with most infant and child safetycar seats and belt positioning booster seatswhen you properly install them. This isbecause they are designed to fill with acooled gas at a lower pressure and at aslower rate than traditional airbags. Afterinflation, the shoulder portion of the seatbeltremains cool to the touch.
The rear inflatable seatbelt consists of thefollowing:
•An inflatable bag in the shoulder seatbeltwebbing.
•Lap seatbelt webbing with automaticlocking mode.
•The same warning light, electroniccontrol and diagnostic unit as used forthe front seatbelts.
•Impact sensors in various parts of thevehicle.
How does the rear inflatable seatbeltsystem work?
WARNING: If a supplementaryrestraint system component has deployed,it will not function again. Have the systemand associated components inspected assoon as possible. Failure to follow thisinstruction could result in personal injuryor death.
The rear inflatable seatbelts function likestandard restraints in everyday usage.

SeatbeltsE146364

During a crash of sufficient force, theinflatable belt inflates from inside thewebbing.
The fully inflated seatbelt's increaseddiameter more effectively holds the occupantin the appropriate seating position, andspreads crash forces over more area of thebody than regular seatbelts. This helpsreduce pressure on the chest and helpscontrol head and neck motion forpassengers.
The rear inflatable seatbelts are designed toinflate in frontal or near-frontal crashes, sideimpact crashes and rollovers. The fact thatthe rear inflatable seatbelt did not inflate ina crash does not mean that something iswrong with the system. Rather, it means theforces were not of the type sufficient tocause activation.
SEATBELT HEIGHT ADJUSTMENT
WARNING: Position the seatbeltheight adjuster so that the belt rests acrossthe middle of your shoulder. Failure toadjust the seatbelt properly could reducethe effectiveness of the seatbelt andincrease the risk of injury in a crash.
To adjust the shoulder belt height, squeezethe button and slide the height adjuster upor down. Release the button and pull downon the height adjuster to make sure it islocked in place.
