X
Replace cap 0085on the filler neck and
tighten.
When doing so, make sure that the cap
engages correctly.
X Check the oil level with the oil dipstick
(Y page 251) or on the display
(Y page 250).
X Close the hood. Coolant
G
WARNING
The engine cooling system is pressurized, par- ticularly when the engine is warm. When
opening the cap, you could be scalded by hotcoolant spraying out. There is a risk of injury.
Let the engine cool down before opening the
cap. Wear eye and hand protection when
opening the cap. Open the cap slowly half a
turn to allow pressure to escape.
Only check the coolant level and/or fill the
coolant if the vehicle is on a level surface and the engine has cooled down. The coolant tem-
perature must be below 122 ‡ (50 †).
! Check the engine cooling and heating sys-
tem regularly for leaks.
If a large quantity of coolant is lost, have the
cause traced and rectified at a qualified
specialist workshop. G
WARNING
Coolant contains glycol and is therefore toxic. Do not swallow the coolant. See a doctor
immediately if you swallow coolant.
Make sure that coolant does not come into
contact with skin, eyes or clothing. In case of
contact with eyes, rinse immediately with
plenty of clean water. Clean affected areas of skin and clothing with soap and water imme-
diately. Change any affected clothing imme-
diately. G
WARNING
If antifreeze comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Let the engine cool down before you add anti-
freeze. Make sure that antifreeze is not spilled
next to the filler neck. Thoroughly clean the
antifreeze from components before starting
the engine.
! Take care not to spill any coolant on pain-
ted surfaces. You could otherwise damage
the paintwork. Example: cap and coolant expansion tank
Checking the coolant level
X Stop your vehicle as far away from traffic as
possible on level ground.
X Switch off the engine.
X Secure the vehicle to prevent it from rolling
away.
X Open the hood (Y page 248).
X Slowly turn cap 0043half a turn counter-
clockwise to allow excess pressure to
escape.
X Turn cap 0043further and remove it.
X Check the coolant level.
If the coolant reaches the maximum mark
on coolant expansion tank 0044, there is
enough coolant in coolant expansion
tank 0044. Engine compartment
253Maintenance and care Z

Adding coolant
X If the coolant drops under the minimum
mark on coolant expansion tank 0044, add
coolant to the maximum mark.
Observe the information on coolant mix-
ture ratio and water quality in the "Techni-
cal data" section (Y page 325). To prevent
damage to the engine cooling system, use
only approved corrosion inhibitor/anti-
freeze that comply with the Mercedes-Benz Specifications for Service Products.
X Replace cap 0043and turn it clockwise to
tighten.
X Start the engine.
X After approximately 5 minutes, switch off
the engine and allow it to cool down.
X Check the coolant level again and add cool-
ant if necessary.
X Close the hood. Brake fluid

WARNING
Service products may be poisonous and haz-
ardous to health. There is a risk of injury.
Comply with instructions on the use, storage
and disposal of service products on the labels of the respective original containers. Always
store service products sealed in their original containers. Always keep service products out
of the reach of children.
Brake fluid is hazardous to health. Also
observe the safety notes in the "Service prod-
ucts and capacities" section (Y page 318).G
WARNING
The brake fluid constantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake fluid is too low, vapor pockets may form in the brake system when the brakes are applied
hard. This would impair braking efficiency.
There is a risk of an accident. You should have the brake fluid renewed at
the specified intervals.
! Brake fluid corrodes paint, plastic and
rubber. If paint, plastic or rubber has come into contact with brake fluid, rinse with
water immediately.
Have the brake fluid renewed every 2 years at
a qualified specialist workshop. Observe the
information on brake fluid in the "Technical
data" section (Y page 324). Check the brake fluid level regularly, e.g.
weekly or when refueling.
Checking the brake fluid level
X Stop your vehicle as far away from traffic as
possible on level ground.
X Switch off the engine.
X Secure the vehicle to prevent it from rolling
away.
X Open the hood (Y page 248).
X Check the brake fluid level.
The brake fluid level is correct if the level is
between the MIN mark and MAX mark on
brake fluid reservoir 0043.
X Close the hood.
! If the brake fluid level in the brake fluid
reservoir has fallen to the MIN mark or
below, check the brake system immedi-
ately for leaks. Also check the thickness of the brake linings. Visit a qualified specialist
workshop immediately.
Do not add brake fluid. This does not cor-
rect the malfunction. 254

Observe the following points when towing
with a tow rope:
R Secure the tow rope on the same side on
both vehicles.
R Ensure that the tow cable is not longer
than legally permitted. Mark the tow
cable in the middle, e.g. with a white
cloth (30 x 30 cm). This will make other
road users aware that the vehicle is being towed.
R Only secure the tow cable to the towing
eye.
R Observe the brake lamps of the towing
vehicle while driving. Always maintain a
distance so that the tow rope does not
sag.
R Do not use steel cables or chains to tow
your vehicle. You could otherwise dam-
age the vehicle.
! Do not use the towing eye for recovery,
this could damage the vehicle. If in doubt,
recover the vehicle with a crane.
! When towing, pull away slowly and
smoothly. If the tractive power is too high,
the vehicles could be damaged.
When towing away, you must observe the
legal requirements for the country in which
you are currently driving.
It is preferable to have the vehicle transpor-
ted on a transporter or trailer instead of tow-
ing it.
The automatic transmission selector lever
must be in the Nposition when towing the
vehicle.
The battery must be connected and charged.
Otherwise, you:
R cannot turn the key in the ignition lock to
position 2
R cannot move the selector lever to position
N on vehicles with automatic transmission
Before the vehicle is towed, switch off the
automatic locking feature (Y page 71). You
could otherwise lock yourself out of the vehi-
cle when pushing or towing away the vehicle. Installing/removing the towing eye
The fixture for the front towing eye is located in the
bumper. Rear towing eye under the bumper, attached to the
chassis
Your vehicle may be equipped with rear tow-
ing eye 0044. If you tow or tow-start a vehicle,
attach the towing device to rear towing
eye 0044.
If your vehicle is equipped with a trailer tow
hitch, attach the towing device to the trailer
tow hitch (Y page 173).
Installing the front towing eye

with a raised front or rear axle:
R the information on towing in the event of
malfunctions (Y page 279) and
R the important safety notes (Y page 277).If the front axle is damaged, raise the vehicle
at the front axle and if the rear axle is dam-
aged, raise the vehicle at the rear axle.
Towing If the front axle is raised, the vehicle may be
towed a maximum of 30 miles (50 km). For a
towing distance of over 30 miles (50 km), the propeller shafts to the driven axles must be
