Overview
The ABS
and stability control systems are comprised of the following subsystems
to assist the driver in maintaining control of the vehicle:
ABS
Curve control
Drive away release (EPB)
EBD
EPB control
ESC
Hill descent control
Hill start assist
Hydraulic fade compensation
RSC
Selectable drive modes
Supplemental braking assist
Supports adaptive cruise control
Supports collision avoidance
Traction control
Trailer sway control
The ABS helps maintain steering control during hard braking by preventing wheel lockup...

Removal
WARNING:
The following procedure prescribes critical repair steps
required for correct restraint system operation during a crash. Follow
all notes and steps carefully. Failure to follow step instructions may
result in incorrect operation of the restraint system and increases the
risk of serious personal injury or death in a crash...
Categories
The front outboard and rear safety restraints
in the vehicle are combination lap and
shoulder belts.
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 that
you securely fasten the tongue in the
buckle.

To unfasten, press the release button
and remove the tongue from the buckle.
