

If Elsa shows other open action(s), inform your customer so that the work can also be completed at
the same time the vehicle is in the workshop for this campaign.

The snow flap in the inlet air box housing may remain partially to fully open. Should this occur,
excess warm air could enter the air intake through the snow flap inlet.
The oxygen sensor will be checked during this service and, if measured degradation
tolerances are met, the sensor will be replaced.
