The front floor mats hook over the floor
anchors, which keep the mats from sliding
forward. To remove a mat for cleaning, turn
the anchor knobs to the unlock position.
When reinstalling the mat after cleaning, turn
the knobs to the lock position.
Do not put additional floor mats on top of
the anchored mat.
Vacuum dirt and dust from the leather frequently. Pay close attention to the pleats
and seams. Clean the leather with a soft cloth dampened with a 90% water and
10% neutral soap solution. Then buff it with a clean, dry cloth. Remove any dust or
dirt on leather surfaces immediately.
