The seat adjustment switch is located on
the entry side of each front seat base.

memory function)*
2Seat cushion tilt
3Seat height
4Backrest tilt
5Seat fore and aft adjustment
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. For addi-
tional information, see “Children in the vehi-
cle” (
page 91).
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.
!When moving the seats, make sure there are
no items in the footwell or behind the seats;
otherwise you could damage the seats.
!When the second-row seats are folded
forward, e.g. for cargo compartment expansion
(
page 304), the front seats may not be moved
to the rearmost position. Otherwise you could
damage the front and second-row seats.
!When adjusting the seat backrest tilt and
head restraint height, make sure the sun visor is
folded up (
page 210). If the head restraint is in
the uppermost position, it could hit and damage
the sun visor.
iVehicles without memory function*:
The seats can be adjusted within 5 minutes after
either front door has been opened. The counter
resets each time

you open or close a front door

you insert the SmartKey into the starter
switch

you remove the SmartKey from the starter
switch

you switch the ignition on or off

92 Safety and Security
Occupant safety
Infant and child restraint systems
We recommend all infants and children be
properly restrained at all times while the
vehicle is in motion.
All lap-shoulder belts except the driver’s
seat belt have special seat belt retractors
for secure fastening of child restraints.
To fasten a child restraint, follow child
restraint instructions for mounting. Then
pull the shoulder belt out completely and
let it retract. During seat belt retraction, a
ratcheting sound can be heard to indicate
that the special seat belt retractor is acti-
vated. The belt is now locked. Push down
on child restraint to take up any slack.
To deactivate, release seat belt buckle and
let seat belt retract completely. To deacti-
vate the special seat belt retractor for the
front passenger seat, the front passenger
seat must be in the most backward posi-
tion. The seat belt can again be used in the
usual manner.The use of infant or child restraints is re-
quired by law in all 50 states, the District
of Columbia, the U.S. territories and all
Canadian provinces.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

injure other persons

get out of the car and injure themselves
or be injured by following traffic
Do not carry heavy or hard objects in the
passenger or cargo compartment unless
they are firmly secured in place. For more in-
formation, see “Loading” (
page 295) and
“Useful features” (
page 315).
Unsecured or improperly positioned cargo
increases a child’s risk of injury in the event
of

strong braking maneuvers

sudden changes of direction

an accident
Warning!G
Never release the seat belt buckle while the
vehicle is in motion, since the special seat
belt retractor will be deactivated.
iFor information on child seats with mounting
fittings for tether anchorages, see “Installation
of infant and child restraint system”
(
page 96).
For information on LATCH-type child seat
mounts, see “Child seat anchors – LATCH type”
(
page 95).
