Seat Belt Service Precautions

  1. Do not bleach or dye the seat belt webbing. Use only the following items in order to clean the seat belt webbing: A mild soap and water solution A soft brush or cloth
  2. Keep sharp edges and damaging objects away from the seat belts. Do not bend or damage any part of the seat belt buckle or the latch plate. Replace any seat belts that are cut or damaged in any manner.
  3. Use only the correct seat belt anchor nuts/bolts. Tighten the correct seat belt anchor nut/bolt/screw to the correct torque value. Refer to «Fastener Tightening Specifications»(ref-277867-S19153936092008012100000) .
  4. Some seat belts and retractors require service as a set with service replacement components only. Do not repair individual components that must require service as a set.
  5. Verify that the replacement part number is correct for the vehicle at that seating position. Do not substitute a seat belt from a different seating position.

Child Seat Restraint System

CAUTIONA child in a rear-facing child restraint can be seriously injured if the right-front passengers air bag inflates. This is because the back of a rear-facing child restraint would be very close to the inflating air bag. NEVER use a rear-facing child restraint in this vehicle. If a forward-facing child restraint is suitable for your child, ALWAYS move the front passenger seat as far back as it will go and then install the child restraint. Be sure the child restraint position does not conflict with any additional requirements provided by the manufacturer. For more information, refer to the vehicle owners manual and the instruction that came with the child restraint.

The child seat may only be used in a forward facing seating location. The child seat should be installed and secured according to the manufacturer's directions. If the child seat has a top strap it will need to be anchored. Refer to Child Restraint Tether Anchor Replacement .

All vehicles are equipped with a dual-mode type retractor with emergency and automatic locking features. The automatic locking feature is for restraint of a child seat. The child seat can be secured by pulling the seat belt all the way out to lock it. Then, tighten the seat belt around the child seat.

If a child seat is to be used in the second seat position, a special dealer-installed anchor must be used to anchor the child seat top strap. (This only applies to the seats designed with the top strap provision and for the vehicles sold in Canada). In order to assure the correct top strap angle, the child seat is only to be used at the seating position for which the top strap anchor is installed.

Fasten Safety Belt Indicator

The fasten safety belt indicator may only be illuminated during RUN. The instrument panel cluster (IPC) illuminates the fasten safety belt indicator under the following conditions

  1. During bulb check
  2. The inflatable restraint sensing and diagnostic module (SDM) sends the status of the driver seat belt switch to the IPC via a class 2 message. If the driver seat belt is unfastened, the IPC will illuminate the fasten safety belt indicator for 72 seconds or until the driver seat belt is fastened. If the driver seat belt is unfastened within 8 seconds following the bulb check, the IPC will send a class 2 serial message requesting 5 chimes to sound.
