the wheels are steel or aluminum.

Lockable wheel nuts: 81 ft. lbs. (110 Nm)
Steel rims – type 1 wheel nuts
Steel rims are normally secured using type 1
wheel nuts, although these rims may also be
secured with type 2 nuts.
WARNING
Never use type 1 wheel nuts for aluminum
wheels. This could cause the wheel to come
loose.
Aluminum wheels – type 2 wheel nuts
Only type 2 wheel nuts can be used for alumi-
num wheels.
NOTE
These nuts can also be used on steel
wheels.
Lockable wheel nut
If steel wheels with lockable wheel nuts are
used in combination with wheel covers, the
lockable wheel nut must be fitted to the stud

otherwise be installed on the wheel.

The issue may be caused by an electrical fault, likely related to a bad ground or faulty wiring. In similar cases, problems with the Central Electronic Module (CEM) or its connectors can cause unusual behavior with interior lights and the dashboard. It’s possible the car is misinterpreting the door open signal or the interior light circuit is interfering with other systems. Checking and reseating the CEM connectors and inspecting grounding points may help identify the cause.
