General notes
Depending on your driving style, the vehicle
consumes up to 0.9 US qt (0.8 l) of oil per
600 miles (1000 km). The oil consumption may
be higher than this when the vehicle is new or if
you frequently drive at high engine speeds.
Depending on the engine, the oil dipstick may be
in a different location.
When checking the oil level:
Rpark the vehicle on a level surface
Rthe engine should be switched off for approx-
imately five minutes if the engine is at normal
operating temperature
Rif the engine is not at normal operating tem-
perature, e.g. if the engine was only started
briefly, wait about 30 minutes before carrying
out the measurement
Checking the oil level using the oil dip-
stick (except Mercedes-AMG S 65)
Example: checking the oil level using the oil
dipstick
XPull oil dipstick:out of the dipstick guide
tube.
XWipe off oil dipstick :.
XSlowly slide oil dipstick :into the guide tube
to the stop, and take it out again.
If the level is between MIN mark =and MAX
mark ;, the oil level is correct.
XIf the oil level has dropped to MIN mark =or
below, add 1.1 US qt (1.0 l)of engine oil.

General notes
Apart from certain country-specific variations,
the vehicles are not equipped with a tire-change
tool kit. If your vehicle is equipped with a tire-
change tool kit, it is located in the stowage well
under the trunk floor. Some tools for changing a
wheel are specific to the vehicle. For more infor-
mation on which tire changing tools are required
and approved to perform a wheel change on
your vehicle, consult a qualified specialist work- shop.
Necessary tire-changing tools can include, for

298Towing and tow-starting
Breakdown assistance

Always observe the instructions and safety
notes in the "Mounting a wheel" section
(
Ypage 321).
The wear patterns on the front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before a clear wear pattern
has formed on the tires. Front tires typically
wear more on the shoulders and the rear tires in the center.
On vehicles that have the same size front and
rear wheels, you can rotate the wheels accord-
ing to the intervals in the tire manufacturer's
warranty book in your vehicle documents. If no
warranty book is available, the tires should be
rotate every 3,000 to 6,000 miles(5,00 0 to
10,000 km). Earlier may be necessary, depend-
ing on the degree of tire wear. Do not change the
direction of wheel rotation.
Clean the contact surfaces of the wheel and the
brake disc thoroughly every time a wheel is rota- ted. Check the tire pressure and reactivate the
tire pressure monitor if necessary (
Ypage 310).
Direction of rotation
Tires with a specified direction of rotation have
additional benefits, e.g. if there is a risk of hydro-
planing. These advantages can only be gained if
the tires are installed corresponding to the
direction of rotation.
An arrow on the sidewall of the tire indicates its
correct direction of rotation.
Storing wheels
Store wheels that are not being used in a cool,
dry and preferably dark place. Protect the tires
from oil, grease, gasoline and diesel.
