15.4 DRIVER ERGONOMICS 
15.4.1  System Description 
Adjustment of the  seats, steering column  and exterior  rear view  mirrors  position is  effected by means  of  control 
switches.  The switches maintain the adjustment facility while  depressed, movement ceasing when the switch is  re- leased. 
Manual adjustment  can be achieved either  with the ignition  key in place  or with  the driver‘s  door open,  or having  been 
closed  within the last 
30 seconds. 
The  system  offers the  following facilities: 
Entry 
/ Exit  mode;  an automatic  seat /column  position setting  for ease  of driver entry  into / exit from  the vehicle. 
Driving position  set; automatic recall  of up to three preferred  settings. 
Passenger seat  set; automatic recall  of up to three preferred  settings. 
Remote recall;  automatic recall of up to two  memory positions  from 
a remote transmitter  (in key  fob). 
Reverse  mirror dip;  automatic adjustment of  passenger rear view  mirror  when reversing. 
U: Vehicles  intended  for the  Japanese  market are fitted with  an additional ‘fold  away’ mirror  function.  This func- tion allows  mirrors  to fold  flat against  the car when  parking  in enclosed  areas. 
15.4.1.1  Entry/  Exit Mode 
Entry / Exit mode  is designed  to give  easier  vehicle  entry and exit  for the driver.  The facility  is selected  by positioning 
the  mode switch, located  on the LH side of the  column  cowl, to ‘auto’  which  designates  the current  seat / column posi- tion, ie driving positions,  as the  memorized  position. On removal  of ignition  key or opening  of driver‘s  door, with igni- tion key still  in place,  the driver’s  seat will move  to the  rear  (current position allowing)  and the column  will adopt  ‘tilt 
away’  mode automatically creating additional  space for  driver exit 
/ entry. Insertion of key  in ignition  or closure of 
driver‘s  door (with  ignition  key in place)  returns  seat / column positions  to the memorized (previous) position. 
Operation  of eitherthe  brake pedal  or 
seat/column manual controls during entry/exit mode  execution  will abort posi- tional  adjustments.  Setting the mode switch  to OFF disables operation of  entry / exit mode. 
15.4.1.2  Driving  Position Set 
Setting of  seat, column  and external  rear view mirrors  to preferred  driving position is  available using the memory  but- tons located  on the drivers door switch  pack. With the ignition  key in place enter  settings to be  memorized  as follows: 
Adjust  seat, column  and mirrors  to desired positions. 
Press  the ’memory’  button 
so that it becomes illuminated. 
Press  button 
1,2 or 3 to store  configuration  within four seconds  of memory  button operation. Memory light  will extin- guish  and a chime  will sound,  indicating  procedure complete. 
The above  procedure may be repeated  two more times  until each  button 
(1,2 & 3) has a preferred position stored  in 
memory,  accommodating different driver  settings.  Operation of any  push-button (1,2 or 3) will re-position  seat col- 
umn  and mirrors  to the stored  settings. 
Memory  recall will operate under  the following  conditions: 
. Ignition key in and  gear  selector  in park. 
8 Ignition  key in and  handbrake  on. 
8 Ignition key out and  driver’s door open  (or having  been closed  within the last 30 seconds). 
Re
-setting  the preferred position  on any  setting button automatically  erases previously  stored information.  Memory 
information  is not  erased if power supply  to the  seat  and column / mirror  control modules  is lost (e.g. battery  discon- nected). 
15.4.1.3 Passenger  Seat Set 
The procedure  for setting  and recalling a preferred  passenger  seat position is identical  to that  for a driving  position. 
Memory  recall will only  operate  with ignition  key in auxiliary position or  passenger door open,  or having  been closed 
within  the last 
30 seconds.
