FASTENING THE SAFETY BELTS
The front outboard and rear safety restraints in your vehicle are
combination lap and shoulder belts.
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.
Using the Safety Belt with Cinch Tongue (Front Center and Rear
Center Seats Only)
The cinch tongue will slide up and down the belt webbing when the belt
is stowed or while putting safety belts on. When the lap and shoulder
safety belt is buckled, the cinch tongue will allow the lap portion to be
shortened, but pinches the webbing to keep the lap portion from getting
longer. The cinch tongue is designed to slip during a crash, so always
wear the shoulder belt properly and don’t allow any slack in either the
lap or shoulder portions.
