299 Operation
Tires and wheels
Tread depth 
Do not allow your tires to wear down too 
far. Adhesion properties on wet roads are 
sharply reduced at tread depths under 1/8in (3 mm).
Treadwear indicators (TWI) are required by 
law. These indicators are located in six 
places on the tread circumference and 
become visible at a tread depth of approx-
imately 
1/16
in (1.6 mm), at which point 
the tire is considered worn and should be 
replaced.
Recommended minimum tire tread depth:
Summer tires 
1/8in (3 mm)
Winter tires 
1/6in (4 mm)
1TWI (T

ndicator)
The treadwear indicator appears as a solid 
band across the tread.Storing tires

Warning!
G
Although the applicable federal motor safety 
laws consider a tire to be worn when the 
treadwear indicators (TWI) become visible at 
approximately 
1/16in (1.6 mm), we recom-
mend that you do not allow your tires
to wear down to that level. As tread depth 
approaches 
1/8in (3 mm), the adhesion 
properties on a wet road are sharply re-
duced.
Depending upon the weather and/or road 
surface (conditions), the tire traction varies 
widely.
!Keep unmounted tires in a cool, dry 
place with as little exposure to light as 
possible. Protect tires from contact 
with oil, grease and gasoline.!Never use a round nozzle to power 
wash tires. The intense jet of water can 
result in damage to the tire.
Always replace a damaged tire. 

332 OperationVehicle careCleaning and care of vehicle
In operation, even while parked, your vehi-
cle is subjected to varying external influ-
ences which, if gone unchecked, can 
attack the paintwork as well as the under-
body 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 chipping
To 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 operation
You should check your vehicle from time to 
time for stone chipping or other damage. 
Any damage should be repaired as soon as 
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.
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. 

437 Technical data
Fuels, coolants, lubricants, etc.
Engine oils
Engine oils are specifically tested for their 
suitability in our engines and durability for 
our service intervals. Therefore, only use 
approved engine oils and oil filters 
required for vehicles with Maintenance 
System (U.S. vehicles) or FSS (Canada 
vehicles). For a listing of approved engine 
oils and oil filters, refer to the Factory 
Approved Service Products pamphlet, or 
contact an authorized Mercedes-Benz 
Center.
Using engine oils and oil filters of 
specification other than those expressly 
required for the Maintenance System 
(U.S. vehicles) or FSS (Canada vehicles), or 
changing of oil and oil filter at change 
intervals longer than those called for by 
the Maintenance System (U.S. vehicles) or 
FSS (Canada vehicles) will result in engine 
damage not covered by the 
Mercedes-Benz Limited Warranty.Please follow Maintenance System 
(U.S. vehicles) or FSS (Canada vehicles) 
recommendations for scheduled oil 
changes. Failure to do so will 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 damage the engine.Damage or 
malfunctions resulting from blending oil 
additives are not covered by the 
Mercedes-Benz Limited Warranty.Air conditioning refrigerant
R-134a (HFC) refrigerant and special PAG 
lubricating oil are used in the air condition-
ing 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. 
Only brake fluid approved by 
Mercedes-Benz is recommended. Your au-
thorized Mercedes-Benz Center will pro-
vide you with additional information.Warning!
G
Under extremely strenuous operating condi-
tions, this moisture content can lead to the 
formation of bubbles in the system, thus re-
ducing the system’s efficiency.
Therefore, the brake fluid must be replaced 
every two years, preferably in the spring. 

440 Technical dataFuels, coolants, lubricants, etc.The coolant solution must be used 
year-round to provide the necessary corro-
sion protection and increase boil-over pro-
tection. Refer to Maintenance Booklet for 
replacement interval.
Coolant system design and coolant used 
determine the replacement interval. The 
replacement interval published in the 
Maintenance Booklet is only applicable if 
MB 325.0 anticorrosion/antifreeze solu-
tion or other Mercedes-Benz approved 
products of equal specification (see 
Factory Approved Service Products pam-
phlet) are used to renew the coolant con-
centration or bring it back up to the proper 
level. 
To provide important corrosion protection, 
the solution must be at least 45% anticor-
rosion/antifreeze [equivalent to freeze 
protection to approximately - 22°F 
(-30°C)]. If you use a solution that is more 
than 55% anticorrosion/antifreeze [freeze 
protection to approximately - 49°F 
(-45°C)], the engine temperature will in-
crease due to the lower heat transfer capa-bility of the solution. Therefore, do not use 
more than this amount of anticorrosion/ 
antifreeze.
If the coolant level is low, water and 
MB 325.0 Anticorrosion/Antifreeze 
should be used to bring it up to the proper 
level (have cooling system checked for 
signs of leakage).
The water in the cooling system must meet 
minimum requirements, which are usually 
satisfied by normal drinking water. If you 
are not sure about the water quality, con-
sult an authorized Mercedes-Benz Center.Anticorrosion/antifreeze
Your vehicle contains a number of alumi-
num parts. The use of aluminum compo-
nents in motor vehicle engines 
necessitates that anticorrosion/antifreeze 
coolant used in such engines be specifical-
ly formulated to protect the aluminum 
parts. (Failure to use such anticorrosion/ 
antifreeze coolant will result in a signifi-
cantly shortened service life.)
Therefore, the following product is strongly 
recommended for use in your vehicle: 
Mercedes-Benz 325.0 anticorrosion/ 
antifreeze agent.
Before the start of the winter season (or 
once a year in hot southern regions), you 
should have the anticorrosion/antifreeze 
concentration checked. The coolant is also 
regularly checked each time you bring your 
vehicle to an authorized Mercedes-Benz 
Center for service.
