smart center.
R Sit properly belted in a position that is
as upright as possible with your back
against the seat backrest.
R Do not lean on the armrests or lift
yoursel ffrom the seat by using the handle
over the door as this may cause the OCS to

center.
R Read and observe all warnings in this
chapter.
Self-test Occupant Classification
System After turning the key in the starter switch
to position 1or 2, the 00090007
indicator lamp located in the center
console illuminates. If an adult occupant
is properly sitting on the passenger seat
and the system senses the occupant as being
an adult, the 00090007indicator
lamp will illuminate and go out after
approximately 4 seconds.
If the seat is not occupied and the system
senses the passenger seat as being empty,
the 00090007indicator lamp will
illuminate and not go out. G
WARNING
If the 00090007indicator lamp does
not illuminate immediately after
switching on the drive system, the system
is not functioning. You must contact an
authorized electric drive smart center
before seating any child on the passenger
seat.
More information can be found in the
“Practical hints” section (Y page 168). G
WARNING
Never place anything between seat cushion
and child seat (e.g. pillow), since it
reduces the effectiveness of the Occupant
Classification System. The bottom of the
child seat must make full contact with the
passenger seat cushion. An incorrectly
mounted child seat could cause injuries to
the child in case of an accident, instead of
increasing protection for the child.
Follow the manufacturer’s instructions for
installation of child seats. Children in the vehicle
If an infant or child is traveling with you
in the vehicle:
X Secure the child using an infant or child
restraint appropriate to the age and size
of the child.
X Make sure the infant or child is properly
secured at all times while the vehicle is
in motion. G
WARNING
Do not leave children unattended in the
vehicle, even if they are secured in achild
restraint system. The children could
R injure themselves on parts of the vehicle
R be seriously or fatally injured through
excessive exposure to extreme heat or
cold
Do not expose the child restraint system to
direct sunlight. The child restraint
system’s metal parts, for example, could
become very hot, and the child could be
burned on these parts.
If children open a door, they could

belt and use an appropriately sized infant
restraint, toddler restraint, or booster
seat recommended for the size and weight
of the child.
Children can be killed or seriously injured
by an inflating air bag. Note the following
important information when circumstances
require you to place a child in the
passenger seat:
R
Your vehicle is equipped with air bag
technology designed to turn off the
passenger front air bag in your vehicle
when the Occupant Classification System
senses the weight of a typical
12‑month‑old child or less along with the
weight of an appropriate child restraint
on the passenger seat.
R A child in a rear-facing child restraint
on the passenger seat may be seriously
injured or even killed if the passenger
front air bag inflates in a collision.
R If you install a rear-facing child
restraint on the passenger seat, make
sure the 00090007indicator lamp
is illuminated, indicating that the
passenger front air bag is deactivated.
Should the 00090007indicator
lamp not illuminate or go out while the
restraint is installed, please check
installation. Periodically check the
00090007indicator lamp while
driving to make sure the
00090007indicator lamp is
illuminated. If the 00090007
indicator lamp goes out or remains out,
do not transport a child on the passenger
seat until the system has been repaired.
A child in a rear-facing child restraint
on the passenger seat may be seriously
injured or even killed if the passenger
front air bag inflates.
R If you place a child in a forward-facing
child restraint on the passenger seat,
move the seat as far back as possible, use
a proper child restraint recommended
for the age, size and weight of the child, and secure child restraint with the
vehicle’s seat belt according to the child
seat manufacturer’s instructions. For
children larger than the typical
12‑month‑old child, the passenger front
air bag may or may not be activated. G
WARNING
Infants and small children should never
share a seat belt with another occupant.
During an accident, they could be crushed
between the occupant and seat belt.
A child’s risk of serious or fatal injuries
is significantly increased if the child
restraints are not properly secured in the
vehicle and/or the child is not properly
secured in the child restraint.
Children too big for a toddler restraint
must ride in a seat using regular seat belt.
Position shoulder belt across chest and
shoulder, not face or neck. A booster seat
may be necessary to achieve proper seat
belt positioning for children over 41 lbs
until they reach a height where a lap-
shoulder belt fits properly without a
booster.
When the child restraint is not in use,
remove it from the vehicle or secure it with
the seat belt to prevent the child restraint
from becoming a projectile in the event of
an accident.
Do not leave children unattended in the
vehicle, even if the children are secured in
a child restraint system. Unsupervised
children in a child restraint system may
use vehicle equipment and may cause an
accident and/or serious personal injury.
If you are using a rear-facing child
restraint system on the passenger seat, you
must verify that the passenger front air bag
is deactivated. When the passenger front
air bag is deactivated, the
00090007indicator lamp is
illuminated (Y page 39).42
