87 Safety and Security
Occupant safety
If you place a child in a forward-facing 
child restraint on the passenger seat, 
move the seat as far back as possible, 
use the proper child restraint recom-
mended 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 
(
page 74). 
Warning!G
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.
Warning!G
Children too big for a toddler restraint must 
ride in seats using regular seat belts. Posi-
tion the 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. A child’s 
unsupervised access to a vehicle could 
result in an accident and/or serious 
personal injury.

340 Operation
Vehicle care
Headliner
Use a soft bristle brush or a dry-sham-
poo cleaner in case of excessive dirt. 
Seat belts
Only use clear, lukewarm water and 
soap.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
Please note that leather upholstery is a 
natural product and is therefore subject 
to a natural aging process. Leather 
upholstery may also react to certain 
ambient influences such as high humidity 
or high temperature by showing wrinkles 
for example.
Wipe leather upholstery with a damp 
cloth and dry thoroughly or clean with 
Mercedes-Benz approved Leather 
Care.Exercise particular care when cleaning 
perforated leather as its underside should 
not become wet.
Wood trims
Dampen cloth using water and use 
damp cloth to clean wood trims in your 
vehicle.
Chrome-plated exhaust tip*
Regular cleaning and care of 
chrome-plated exhaust tips will help 
to maintain their shine and the classy 
appearance.
Use Mercedes-Benz approved Chrome 
Polishing Paste each time the vehicle 
has been washed, especially during the 
winter.
!The seat belts must not be treated with 
chemical cleaning agents. Do not dry the seat 
belts at temperatures above 176°F (80°C) or in 
direct sunlight.
Warning!G
Do not bleach or dye seat belts as this may 
severely weaken them. In a crash they may 
not be able to provide adequate protection.
!Wipe with light pressure, to avoid damage to 
the upholstery.
!Do not use solvents like tar remover or 
wheel cleaner nor polishes or waxes as these 
may be abrasive.
!Do not use alkaline cleaners such as wheel 
cleaners as they could cause corrision.
