Fastening the safety belts
The front outboard and rear safety restraints in your vehicle are combination lap and shoulder belts.
The presenter arm (available on the coupe only) is intended to improve access to the safety belt and to allow access to the rear seat.

Rotate the presenter arm toward the front of the vehicle until it locks into place. This allows easier access to the front safety belt for the front seat occupant.
To access the second row seats, rotate the arm back to its original position against the trim panel.

1. Insert the belt tongue into the proper buckle (the buckle closest to the direction the tongue is coming from) until you hear a snap and feel it latch. Make sure the tongue is securely fastened in the buckle.

2. To unfasten, press the release button and remove the tongue from the buckle.
Restraint of Pregnant Women

Pregnant women should always wear their safety belts. The lap belt portion of a combination lap and shoulder belt should be positioned low across the hips below the belly and worn as tight as comfort will allow. The shoulder belt should be positioned to cross the middle of the shoulder and the center of the chest.
Safety Belt Locking Modes
All safety restraints in the vehicle are combination lap and shoulder belts. The driver safety belt has the first type of locking mode, and the front outboard passenger and rear seat safety belts have both types of locking modes described as follows:
Vehicle Sensitive Mode
This is the normal retractor mode, which allows free shoulder belt length adjustment to your movements and locking in response to vehicle movement. For example, if the driver brakes suddenly or turns a corner sharply, or the vehicle receives an impact of about 8 km/h or more, the combination safety belts will lock to help reduce forward movement of the driver and passengers.
In addition, the retractor is designed to lock if the webbing is pulled out too quickly. If this occurs, let the belt retract slightly and pull webbing out again in a slow and controlled manner.
Automatic Locking Mode
In this mode, the shoulder belt is automatically pre-locked. The belt will still retract to remove any slack in the shoulder belt. The automatic locking mode is not available on the driver safety belt.
When to Use the Automatic Locking Mode
This mode should be used any time a child safety seat, except a booster, is installed in passenger front or rear seating positions. Children 12 years old and under should be properly restrained in a rear seating position whenever possible. See the Child Safety chapter.
How to Use the Automatic Locking Mode

1. Buckle the combination lap and shoulder belt.
2. Grasp the shoulder portion and pull downward until the entire belt is pulled out.
3. Allow the belt to retract. As the belt retracts, you will hear a clicking sound.
This indicates the safety belt is now in the automatic locking mode.
How to Disengage the Automatic Locking Mode
Unbuckle the combination lap and shoulder belt and allow it to retract completely to disengage the automatic locking mode and activate the vehicle sensitive (emergency) locking mode.
Safety Belt Extension Assembly
If the safety belt is too short when fully extended, you can obtain a safety belt extension assembly from an authorized dealer.
Use only extensions manufactured by the same supplier as the safety belt. Manufacturer identification is located at the end of the webbing on the label. Also, use the safety belt extension only if the safety belt is too short for you when fully extended.
