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 
backrest in an excessively reclined position 
as this 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 ab-
domen or neck. That could cause serious or 
fatal injuries. The seat backrest and seat 
belts provide the best restraint when the 
wearer is in a nearly upright position and 
belts are properly positioned on the body. 
Your seat must be adjusted so that you can 
correctly fasten your seat belt (
page 45).
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 
SmartKey or the SmartKey with 
KEYLESS-GO* from the starter switch, take 
it with you, and lock the vehicle.
Even with the SmartKey or the SmartKey 
with KEYLESS-GO* removed from the start-
er switch or the SmartKey with 
KEYLESS-GO* removed from the vehicle, 
the power seats can be operated when the 
respective door is open. Therefore, do not 
leave children unattended in the vehicle, or 
with access to an unlocked vehicle. Unsu-
pervised use of vehicle equipment may 
cause an accident and/or serious personal 
injury.

Special BabySmart
TM compatible child 
seats, designed for use with the 
Mercedes-Benz system and available at 
any authorized Mercedes-Benz Center, are 
required for use with the BabySmart
TM air-
bag deactivation system. With the special 
child seat properly installed, the passenger 
front airbag will not deploy.The 7indicator lamp located on the 
glove box will be illuminated, except with 
the SmartKey removed or in starter switch

 without special 
child seat installed
After turning the SmartKey in the starter 
switch to position1 or2 or pressing the 
KEYLESS-GO* start/stop button once or 
twice, the 7 indicator lamp located on 
the glove box comes on for approximately 
six seconds and then goes out.
If the indicator lamp should not come on or 
is continuously lit, the system is not func-
tioning. You must see an authorized 
Mercedes-Benz Center before seating any 
child on the passenger seat.
Warning!
G
Children too big for child restraint systems 
should use regular seat belts. Position the 
shoulder belt across chest and shoulder, not 
face or neck. A booster seat may be neces-
sary to achieve proper belt positioning for 
children from 41 lbs until they reach a 
height where a lap/shoulder belt fits proper-
ly without a booster.
When the child restraint is not in use, re-
move 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 ac-
cident.
Do not leave children unattended in the ve-
hicle, even if the children are secured in a 
child restraint system. Unsupervised chil-
dren in a child restraint system may use ve-
hicle equipment and cause an accident 
and/or serious personal injury.

321 Operation
Vehicle care
Upholstery
Using aftermarket seat covers or wearing 
clothing that have the tendency to give off 
coloring (e.g. when wet, etc.) may cause 
the upholstery to become permanently dis-
colored. By lining the seats with a proper 
intermediate cover, contact-discoloration 
will be prevented.
Leather upholstery
Wipe leather upholstery with a damp cloth 
and dry thoroughly or clean with 
Mercedes-Benz approved Leather Care. 
Exercise particular care when cleaning per-
forated leather as its underside should not 
become wet.Plastic and rubber parts
Do not use oil or wax on these parts.
Wood trims
Dampen cloth using water and use damp 
cloth to clean wood trims in your vehicle. 
Do not use solvents like tar remover or 
wheel cleaner nor polishes or waxes as 
these may be abrasive.
