Cleaning and care of the vehicle
While in operation, even while parked, your 
vehicle is subjected to varying external in-
fluences which, if gone unchecked, can at-
tack the paintwork as well as the 
underbody and cause lasting damage.
Such damage is caused not only by ex-
treme and varying climatic conditions, but 
also by:
Air pollution
Road salt
Tar, gravel and stone chippingTo avoid paint damage, you should imme-
diately remove:
Grease and oil
Fuel
Coolant
Brake fluid
Bird droppings
Insects
Tree resins, etc.
Frequent washing reduces and / or elimi-
nates the aggressiveness and potency of 
the above adverse influences.
More frequent washings are necessary to 
deal with unfavorable conditions:
Near the ocean
In industrial areas (smoke, exhaust 
emissions)
During winter operationYou should check your vehicle from time to 
time for stone chipping or other damage. 
A n y  d a m a g e  s h o u l d  b e  r e p a i r e d  a s  s o o n  a s  
possible to prevent corrosion.
In doing so, do not neglect the underbody 
of the vehicle. A prerequisite for a thor-
ough check is a washing of the underbody 
followed by a thorough inspection. Dam-
aged areas need to be re-undercoated.
Your vehicle has been treated at the facto-
ry with a wax-base rustproofing in the body 
cavities which will last for the lifetime of 
the vehicle. Post-production treatment is 
neither necessary nor recommended by 
Mercedes-Benz because of the possibility 
of incompatibility between materials used 
in the production process and others ap-
plied later.
We have selected car-care products and 
compiled recommendations which are 
specially matched to our vehicles and 
which always reflect the latest technology. 
You can obtain Mercedes-Benz approved 
car-care products at your authorized 
Mercedes-Benz Center.
Warning!
G
Many cleaning products can be hazardous. 
Some are poisonous, others are flammable. 
Always follow the instructions on the partic-
ular container. Always open your vehicle’s 
doors or windows when cleaning the inside.
Never use fluids or solvents that are not de-
signed for cleaning your vehicle.

Engine oils
Engine oils are specifically tested for their 
suitability in our engines. Therefore, only 
use engine oils recommended by 
Mercedes-Benz. Information on recom-
mended brands is available in the Factory 
Approved Service Products pamphlet, or at 
your authorized Mercedes-Benz Center.
Please follow FSS recommendations for 
scheduled oil changes. Failure to do so 
could result in engine damage not covered 
by the Mercedes-Benz Limited Warranty.
Engine oil additives
Do not blend oil additives with engine oil. 
They may be harmful to the engine opera-
tion.
Damage or malfunctions resulting from 
blending oil additives are not covered by 
the Mercedes-Benz Limited Warranty.Air conditioner refrigerant
R-134a (HFC) refrigerant and special PAG 
lubricating oil are used in the air condition-
er system.
Never use R-12 (CFC) or mineral-based lu-
bricating oil, otherwise damage to the 
system will occur.
Brake fluid
During vehicle operation, the boiling point 
of the brake fluid is continuously reduced 
through the absorption of moisture from 
the atmosphere. Under extremely strenu-
ous operating conditions, this moisture 
content can lead to the formation of bub-
bles in the system, thus reducing the sys-
tem’s efficiency.
Therefore, the brake fluid must be re-
placed every two years, preferably in the 
spring.
Only brake fluid approved by 
Mercedes-Benz is recommended. Your au-
thorized Mercedes-Benz Center will pro-
vide you with additional information.
