adjusts the positions of the steering wheel and
outside mirrors when the seat is adjusted using
the power seat switches.
However, the steering wheel and outside mirrors
will not move if the seat is adjusted over
the maximum thresholds. The system considers
that the steering wheel and outside mirror
adjustments are not necessary because the
seat may not be adjusted for the driving position.
Note that the function is set to disabled as
the factory default setting.
The seat synchronization function operates under
the following conditions:
c The ignition switch is in the ON position.
c The selector lever is in the P (Park) position
(Automatic Transmission models) or the
parking brake is applied (Manual Transmission
models).
c The seatback is raised (Coupe).
If the outside mirrors or the steering wheel
reaches its maximum adjustment, the function
is automatically disabled. Restart the function
by selecting a previously stored seat memory
position using the memory switches (1 or 2). An
Intelligent Key that was previously linked to the
stored seat memory can also be used to restart
the function.
If a seat position was not previously stored in
the seat memory, restart the function by adjusting
the steering wheel and outside mirrors
manually for your best driving position and then
drive the vehicle above 4 MPH (7 km/h).
