Seats
With the easy-entry/exit feature activated
the steering wheel tilts upwards and the
driver’s seat moves a few inches to the
rear when you:
remove the SmartKey from the starter
switch,
or
open the driver’s door with the
SmartKey in starter switch position 0
or 1 or the KEYLESS-GO* start/stop
button (
page 337) in position 1
iFor safety reasons, the driver’s seat will not
return to its last set position with the easy-en-
try/exit feature activated if the system recogniz-
es the last set position as an extreme forward
position. Instead, the driver’s seat will remain at
or move to a factory-set maximum forward posi-
tion. To again fully return the driver’s seat to your
last set position or to memory position, adjust
the seat to the desired position or press and hold
the respective memory position button
(
page 358).
iThe last set driver’s seat and steering wheel
positions are stored when
the ignition is switched off (page 336)
the position is stored in memory
(
page 357)
iIf the current position for the steering wheel
is in the uppermost tilt position, the steering
wheel will no longer be able to move upward
when the easy-entry/exit feature is activated.
If the current seat position falls into a factory-set
position range and the system recognizes the
current seat position to be rearward enough for
easy entry and exit, the driver’s seat will not
move to the rear when the easy-entry/ exit fea-
ture is activated.
The adjustment procedure is briefly interrupted
when the engine is started.
Warning!G
Let the system complete the adjustment
procedure before setting the vehicle in mo-
tion. All driver’s seat and steering wheel ad-
justments must be completed before setting
the vehicle in motion. Driving off with the
driver’s seat/steering wheel still adjusting
could cause the driver to lose control of the
vehicle.
