Important safety notes G
WARNING
When the EASY-ENTRY/EXIT feature adjusts
the steering wheel, you and other vehicle
occupants – particularly children – could
become trapped. There is a risk of injury.
While the EASY-ENTRY/EXIT feature is mak-
ing adjustments, make sure that no one has
any body parts in the sweep of the steering

If someone is trapped:
R press one of the memory function position
buttons, or
R move the switch for steering wheel adjust-
ment in the opposite direction to that in
which the steering wheel is moving.

when unattended. There is a risk of injury.
When leaving the vehicle, always take the key with you and lock the vehicle. Never leave
children unattended in the vehicle. G
WARNING
If you drive off while the EASY-ENTRY/EXIT
feature is making adjustments, you could lose
control of the vehicle. There is a risk of an
accident. Always wait until the adjustment process is
complete before driving off.
The EASY-ENTRY/EXIT feature makes getting in and out of your vehicle easier.
