For 1990-2009 cars only

If your vehicle has all-wheel drive (AWD), the AWD system operates automatically without any action required by the driver. If the front drive wheels begin to slip, the rear wheels will automatically begin to drive the vehicle as required. There may be a slight engagement noise during hard use but this is normal.

This light is located on the instrument panel cluster.

It will come on and stay on to indicate there may be a problem with the drive system and service is required. If the light stays on, it must be reset. To reset the light, turn the ignition off and then back on again. If the light stays on, see your dealer/retailer for service.

If the vehicle is exposed to extended heavy AWD usage, the AWD system will shut itself off to protect the system from overheating. When the system cools down, the AWD system will activate itself again automatically; this cool-down can take up to 20 minutes depending on outside temperature and vehicle use.
