Some customers may comment that the outside rearview mirror is loose or moves out of adjustment while driving the vehicle.
The mirror movement may be caused by insufficient friction between the inner and outer cups that retain the mirror.
DO NOT REPLACE THE MIRROR ASSEMBLY .
Follow the procedure outlined below to adjust the retaining ring, which will increase the friction between the inner and outer cups of the mirror assembly.
5.1. | Insert your fingers as far as possible behind the mirror toward the center of the back. |
5.2. | With force sufficient to disengage the snap-fits from the adjuster mechanism, pull the mirror back out of the housing. |
8.1. | Place foam below the mirror assembly to catch the glass if the mirror should fall. |
8.2. | Hold the assembly so that the mirror glass is face down. While taking care that the mirror housing is not scratched, slap the upward surface of the housing. The mirror glass should stay retained in the housing. |
Tighten
Tighten the nuts to 25 N·m (18 lb ft).
