Warning!G
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front seat-
ing position. Thus, we strongly recommend
that children be placed in the rear seats
whenever possible. Regardless of seating
position, children 12 years old and under
must be seated and properly secured in an
appropriately sized infant restraint, toddler
restraint, or booster seat recommended for
the size and weight of the child.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and
the child is not properly secured in the child
restraint.
iAfter unlocking the vehicle or turning off the
engine, the seat adjustment can be operated for
up to approximately 3 minutes with the
SmartKey or KEYLESS-GO* (Canada only) in
starter switch position0 or removed from the
starter switch.
Vehicles with memory function* (Canada only):
The memory function* is operational at any time.
Seat and steering wheel adjustment is always
possible.

Steering wheel
Easy-entry/exit feature* (Canada only)
This feature allows for easier entry into and
exit from the vehicle. When entering and
exiting the vehicle, the steering wheel is in
its uppermost position.
The easy-entry/exit feature can be activat-
ed or deactivated in the
Convenience sub-
menu of the control system (
page 174).With the easy-entry/exit feature activated
the steering wheel tilts upwards when you:

remove the SmartKey from the starter
switch,
or

open the driver’s door with the
SmartKey in starter switch position0
or1 or the KEYLESS-GO* start/stop
button in position1
Warning!G
You must make sure no one can become
trapped or injured by the moving steering
wheel when the easy-entry/exit feature is
activated.
To stop steering wheel movement, do one of
the following:

Move steering wheel adjustment stalk.

Press one of the memory position but-
tons or the memory buttonM.
Do not leave children unattended in the ve-
hicle, or with access to an unlocked vehicle.
Children could open the driver’s door and
unintentionally activate the easy-entry/exit
feature, which could result in an accident
and/or serious personal injury.
Warning!G
Let the system complete the adjustment
procedure before setting the vehicle in mo-
tion. All steering wheel adjustments must be
completed before setting the vehicle in mo-
tion. Driving off with the steering wheel still
adjusting could cause the driver to lose con-
trol of the vehicle.
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.
The adjustment procedure is briefly interrupted
when the engine is started.
