Warning!
G
When leaving the vehicle, always remove the
SmartKey from the starter switch and lock
the vehicle. Do not leave children unattend-
ed in the vehicle, or with access to an un-
locked vehicle. Unsupervised use of vehicle
equipment may cause an accident and/or
serious personal injury.iVehicles with automatic transmission:
The SmartKey can only be removed
from the starter switch with the gear
selector lever in positionP.
!If the key is left in starter switch
position0 for an extended period of
time, it can no longer be turned in the
starter switch.

Remove the key from the starter
switch and reinsert.
If the key can still not be turned, the
battery may not be sufficiently
charged.


Check the battery and charge it if
necessary (
page 240).


Get a jump start (
page 306).
To prevent accelerated battery dis-
charge and a possible dead battery, al-
ways remove the key from the starter
switch.

32 Getting startedAdjusting
AdjustingSeats
The seats can be adjusted either manually
or electrically, depending on the vehicle’s
equipment.Warning!
G
All seat, head restraint, steering wheel, and
rear view mirror adjustments, as well as fas-
tening of seat belts, must be done before
the vehicle is put into motion.Warning!
G
Do not adjust the driver’s seat while driving.
Adjusting the seat while driving could cause
the driver to lose control of the vehicle.
Never ride in a moving vehicle with the seat
back reclined. Sitting in an excessively re-
clined position can be dangerous. You could
slide under the seat belt in a collision. If you
slide under it, the belt would apply force at
the abdomen or neck.
That could cause serious or fatal injuries.
The seat back and seat belts provide the
best restraint when the wearer is in an up-
right position and belts are properly posi-
tioned on the body. Your seat must be
adjusted so that you can correctly fasten
your seat belt (
page 41).
Never place hands under the seat or near
any moving parts while a seat is being ad-
justed.
Warning!
G
When leaving the vehicle, always remove the
key from the starter switch, and lock your
vehicle.
The power seats* can also be operated with
the driver’s or front passenger door open.
Do not leave children unattended in the ve-
hicle, or with access to an unlocked vehicle.
Unsupervised use of vehicle equipment may
cause an accident and/or serious personal
injury.
Warning!
G
Children 12 years old and under must never
ride in the front seat, except in a
Mercedes-Benz authorized BabySmart
TM
compatible child seat, which operates with
the BabySmart
TM system installed in the ve-
hicle to deactivate the passenger side front
airbag when it is properly installed. Other-
wise they will be struck by the airbag when
it inflates in a crash. If this happens, serious
or fatal injury will result.
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front seat-
ing positions. Infants and small children
must ride in back seats and be seated in an
appropriate infant or child restraint system,
which is properly secured with the vehicle’s
seat belt and top tether strap, or secured via
lower anchors and top tether strap, fully in
accordance with the child seat manufactur-
er’s instructions.

65 Safety and Security
Occupant safety
Children in the vehicle
If an infant or child is traveling with you in
the vehicle:

Secure the child using an infant or child
restraint appropriate to the age and
size of the child and recommended for
use by Mercedes-Benz.


Ensure that the infant or child is prop-
erly secured by a belt at all times while
the vehicle is in motion.
Infant and child restraint seats and infor-
mation on choosing an appropriate re-
straint system can be obtained from any
Mercedes-Benz Center.
Infant and child restraint systems
Use only a BabySmart
TM compatible child
restraint for the front passenger seat in
this vehicle.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 re-
straint instructions for mounting. Then pull
the shoulder belt out completely and let it
retract. During the 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. The seat
belt can again be used in the usual man-
ner.
iInformation on child seats with anchor
fittings for tether anchorages
(page 68).
For information on child seat anchors -
“LATCH” type (
page 69).
Warning!
G
Never release the seat belt buckle while the
vehicle is in motion, since the special seat
belt retractor will be deactivated.!The use of infant or child restraints is
required by law in all 50 states, the
District of Columbia, the U.S. territo-
ries, and all Canadian provinces.
Infants and small children should be
seated in an appropriate infant or child
restraint system properly secured by a
lap-shoulder belt or, if so equipped, a
child restraint lower anchorage system
that complies with U.S. Federal Motor
Vehicle Safety Standards 213 and 225
and Canadian Motor Vehicle Safety
Standards 213 and 210.2.
A statement by the child restraint man-
ufacturer of compliance with this stan-
dard can be found on the instruction

Installation of infant and child restraint
systems
This vehicle is equipped with tether an-
chorages for a top tether strap at each of
the rear seating positions.
1Cover of top anchorage ring
Make sure that the rear backrest is
locked in its upright position
(page 200).

Remove cover1 from anchorage
ring3.

Guide tether strap between head
restraint and top of seat back.
Head restraint must be installed (if
removable) and positioned such that
the top tether strap can pass freely
between the head restraint and top of
seat back.
Make sure that the tether strap is not
twisted.
Warning!
G
Please be sure to check the indicator every
time you use the special system child seat.
Should the light go out while the restraint is
installed, please check installation. If the
light remains out, do not use the
BabySmart
TM restraint to transport children
on the front passenger seat until the system
has been repaired.
Warning!
G
Do not place powered-on laptops, cell
phones and like electronic devices on the
front passenger seat. Signals from such de-
vices may interfere with the BabySmart
TM
system. Such signal interference may cause
the
7
indicator lamp not to come on
during self-test or be continuously lit, indi-
cating that the system is not functioning.
Warning!
G
Always lock backrest in its upright position
when rear seat bench is occupied by pas-
sengers, or the extended cargo area is not in
use. Check for secure locking by pushing
and pulling on the backrest.
