Washer fluid
Check level
The fluid level has dropped to about 1/3 of total reservoir capacity.
Add washer fluid (
page 278).
Warning!
G
Do not spill antifreeze on hot engine parts. 
Antifreeze contains ethylene glycol which 
may ignite when if it comes into contact with 
hot engine parts. You could be seriously 
burned.

402 Practical hintsBatteriesWarning!
G
Failure to follow these instructions can re-
sult in severe injury or death.
Never lean over batteries while connecting, 
you might get injured.
Battery fluid contains sulfuric acid. Do not 
allow this fluid to come in contact with eyes, 
skin or clothing. In case it does, immediately 
flush affected area with water and seek 
medical help if necessary.
A battery will also produce hydrogen gas, 
which is flammable and explosive. Keep 
flames or sparks away from battery, avoid 
improper connection of jumper cables, 
smoking, etc.
!Never loosen or detach battery termi-
nal clamps while the engine is running 
or the SmartKey is in the starter switch. 
Otherwise the alternator and other 
electronic components could be se-
verely damaged.
Have the starter battery checked regu-
larly by an authorized Mercedes-Benz 
Center.
Refer to Maintenance Booklet for main-
tenance intervals or contact an autho-
rized Mercedes-Benz Center for further 
information.
Warning!
G
Do not place metal objects on the battery as 
this could result in a short circuit. 
Use leak-proof batteries only to avoid the 
risk of acid burns in the event of an acci-
dent.

406 Practical hintsJump starting
If the starter battery is discharged, the en-
gine can be started with jumper cables and 
the battery of another vehicle. Observe the 
following:
Jump starting should only be performed 
when the engine and catalytic convert-
er are cold.
Do not start the engine if the battery is 
frozen. Let the battery thaw out first.
Only jump start from batteries with the 
same voltage rating (12 V). Jump start-
ing with a more powerful battery could 
damage the vehicle’s electrical system, 
which will not be covered by the 
Mercedes-Benz Limited Warranty.
Only use jumper cables with sufficient 
cross section and insulated terminal 
clamps.
Always make sure the jumper cables 
are not on or near pulleys, fans, or oth-
er parts that move when an engine is 
started or running.
Warning!
G
Failure to follow these directions will cause 
damage to the electronic components, and 
can lead to a battery explosion and severe 
injury or death.
Never lean over batteries while connecting 
or jump starting, you might get injured.
Battery fluid contains sulfuric acid. Do not 
allow this fluid to come in contact with eyes, 
skin or clothing. In case it does, immediately 
flush affected area with water, and seek 
medical help if necessary.
A battery will also produce hydrogen gas, 
which is flammable and very explosive. Keep 
flames or sparks away from battery, avoid 
improper connection of jumper cables, 
smoking, etc.
Attempting to jump start a frozen battery 
can result in it exploding, causing personal 
injury.
Read all instructions before proceeding.
!Jump starting may only be performed 
on the battery installed in the engine 
compartment.
Avoid repeated and lengthy starting at-
tempts.
Do not attempt to start the engine us-
ing a battery quick charge unit.
If the engine does not run after several 
unsuccessful starting attempts, have it 
checked at the nearest authorized 
Mercedes-Benz Center.
Excessive unburned fuel generated by 
repeated failed starting attempts may 
damage the catalytic converter and 
may present a fire risk.
Make sure the jumper cables do not 
have loose or missing insulation.
Make sure the cable clamps do not 
touch any other metal part while the 
other end is still attached to a battery.

433 Technical data

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 re-
quired 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 Ap-
proved Service Products pamphlet, or con-
tact an authorized Mercedes-Benz Center.
Using engine oils and oil filters of specifica-
tion other than those expressly required 
for the Maintenance System 
(U.S. vehicles) or FSS (Canada vehicles), or 
changing oil and oil filter at change inter-
vals 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.
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 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.

438 Technical dataFuels, coolants, lubricants, etc.Windshield and headlamp washer system
Both the windshield and headlamp washer 
systems are supplied from the windshield 
washer fluid reservoir.
The windshield and headlamp washer fluid 
reservoir has a capacity of approx. 
7.4 US qt (7 l).
Refill the reservoir with MB Windshield 
Washer Concentrate and water (or con-
centrate and commercially available 
premixed windshield washer 
solvent / antifreeze, depending on am-
bient temperatures).Windshield and headlamp washer fluid 
mixing ratio
For temperatures above freezing point, use 
MB Windshield Washer Concentrate “S” 
and water:
1 part “S” to 100 parts water
(1.34 fl oz [40 ml] “S” to 1 gal [4.0 l] 
water)
For temperatures below freezing point, use 
MB Windshield Washer Concentrate “S” 
and commercially available premixed 
windshield washer solvent / antifreeze:
1 part “S” to 100 parts solvent
(1.34 fl oz [40 ml] “S” to 1 gal [4.0 l] 
solvent).
Warning!
G
Washer solvent/antifreeze is highly flamma-
ble. Do not spill washer solvent/antifreeze 
on hot engine parts because it may ignite 
and burn. You could be seriously burned.
