Engine compartment
Checking engine oil level with the oil
dipstick
When checking the oil level

the vehicle must be parked on level
ground


with the engine at operating tempera-
ture, the vehicle must have been sta-
tionary for at least 5 minutes with the
engine turned off


with the engine not at operating tem-
perature yet, the vehicle must have
been stationary for at least 30 minutes
with the engine turned off1Oil dipstick
2Upper (max) mark
3Lower (min) mark
To check the engine oil level with the oil
dipstick, do the following:

Open the hood (
page 297).

Pull out oil dipstick1.

Wipe oil dipstick1 clean.

Fully insert oil dipstick1 into the
dipstick guide tube.

Pull out oil dipstick1 again after
approximately 3 seconds to obtain ac-
curate reading.
The oil level is correct when it is be-
tween the lower (min) mark3 and
upper (max) mark2 of oil dipstick1.

If necessary, add engine oil.
For adding engine oil, see “Adding en-
gine oil” (
page 300).
For more information on engine oil, see
“Fuels, coolants, lubricants, etc.”
(
page 440).
For more information on messages in the
multifunction display concerning engine
oil, see the “Practical hints” section
(page 375).iThe filling quantity between the upper
and lower marks on the oil dipstick is
approximately 2.1 US qt. (2.0 l).

317 Operation
Tires and wheels

Install the valve cap.

Repeat this procedure for each tire.Run Flat Indicator* (Canada only)
While the vehicle is being driven, the Run
Flat Indicator monitors the set tire inflation
pressures by evaluating each wheel’s rota-
tional speed. This allows the system to de-
tect a significant loss of pressure in a tire.
If a wheel’s rotational speed changes due
to falling tire inflation pressure, you will
see a corresponding warning message in
the multifunction display.
The Run Flat Indicator* may function in a
restricted manner or with a delay if:


snow chains are mounted to the
vehicle


winter road conditions prevail in
presence of ice and snow


you are driving on a loose surface (e.g.
sand or gravel)


you are driving in a very sporty manner
(involving rapid acceleration or high
speeds in curves)
iIf you have overfilled the tire, release
tire inflation pressure by pushing the
metal stem of the valve with e.g. a tip of
a pen. Then recheck the tire inflation
pressure with the tire gauge.
Warning!
G
When the multifunction display shows the
message
Tire pressure Check tires
,
one or more of your tires is significantly un-
der-inflated. You should stop and check
your tires as soon as possible, and inflate
them to the proper tire inflation pressure as
indicated on the vehicle’s tire information
placard. Driving on a significantly under-in-
flated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability. Each tire, including the
spare, should be checked monthly when
cold and set to the recommended tire infla-
tion pressure as specified in the vehicle
placard and owner’s manual.

or

Wait until the messageTire pres. OK now?disappears.Potential problems associated with
underinflated and overinflated tires
Underinflated tire inflation pressure
Underinflated tires can:


cause excessive and uneven tire wear


adversely affect fuel economy


lead to tire failure from being
overheated


adversely affect handling
characteristics
Warning!
G
The Run Flat Indicator* can only warn you in
a reliable manner if you have set the correct
tire inflation pressures for each tire.
If an incorrect tire inflation pressure was
set, the system will monitor the pressure
according to the incorrect value.
Warning!
G
Follow recommended tire inflation pres-
sures.
Do not underinflate tires. Underinflated tires
wear excessively and / or unevenly,
adversely affect handling and fuel economy,
and are more likely to fail from being
overheated.

338 OperationMaintenanceWe strongly recommend that you have
your vehicle serviced by an authorized
Mercedes-Benz Center, in accordance with
the Maintenance Booklet at the times
called for by the maintenance service
indicator display.
Failure to have the vehicle maintained in
accordance with the Maintenance Booklet
and maintenance service indicator at the
designated times /mileage will result in
vehicle damage not covered by the
Mercedes-Benz Limited Warranty.Maintenance service indicator
message
The maintenance service indicator will
notify you when your next maintenance
service is due.
Starting approximately 1 month before
your next maintenance service is due, one
of the following messages will appear in
the multifunction display while you are
driving or when you switch on the ignition
(example service A):Service A in XXXXX Miles
(Km)
Service A in XXX Days
Service A due now
The type of maintenance service due is
indicated in the multifunction display:
9Basic service (A)
½Extended service (B)
iVehicles equipped with FSS (F

vehicles): The interval between
maintenance services depends on your
driving habits. A gentle driving style,
moderate engine speeds and the
avoidance of short-distance trips will
lengthen the interval between services.

339 Operation

Clearing the maintenance service
indicator message
The maintenance service indicator is
automatically cleared

after approximately 10 seconds when
you switch on the ignition or when
reaching the maintenance service
threshold while driving


after approximately 30 seconds, once
the suggested maintenance service
term has passed
You can also clear it yourself.
1Reset button

maintenance service term, you will see the
following message in the multifunction
display:
Service A exceeded by XXXX Miles
(Km)
Service A exceeded by XXX DaysIn addition, a signal sounds when the
message appears.
Any authorized Mercedes-Benz Center will
reset the maintenance service indicator
following a completed maintenance
service.Calling up the maintenance service

358 Practical hintsWhat to do if …Vehicle status messages in the multifunction display
Warning and malfunction messages
appear in the multifunction display located
in the instrument cluster.
Certain warning and malfunction messag-
es are accompanied by an audible signal.
Address these messages accordingly and
follow the additional instructions given in
this Operator’s Manual.
Selecting the vehicle status message
memory menu in the control system
(page 138) displays both cleared and
uncleared messages.
High-priority messages appear in the
multifunction display in red color.Certain messages of high priority cannot
be cleared from the multifunction display
using the reset button (
page 127) or
buttonj, k, ÿ, orè on the
steering wheel.
Other messages of high priority and
messages of less immediate priority can
be cleared from the multifunction display
using the reset button (page 127) or
buttonj, k, ÿ, orè on the
steering wheel. They are then stored in the
vehicle status message memory
(
page 138). Remember that clearing a
message will only make the message
disappear. Clearing a message will not
correct the condition that caused the
message to appear.
Warning!
G
All categories of messages contain
important information which should be
taken note of and, where a malfunction is
indicated, addressed as soon as possible at
an authorized Mercedes-Benz Center.
Failure to repair condition noted may cause
damage not covered by the Mercedes-Benz
Limited Warranty, or result in property
damage or personal injury.Warning!
G
No messages will be displayed if either the
instrument cluster or the multifunction
display is inoperative.
Contact your nearest authorized
Mercedes-Benz Center.

tifunction display in the instrument cluster (
page 24) for the following:
With the seat unoccupied and the ignition turned on,


the 56indicator lamp on the center console should illuminate and remain

60 seconds for the system to complete the necessary check cycles and to make
sure neither message appears in the multifunction display.
If above conditions are met, you can occupy the front passenger seat again. Depend-
ing on the front passenger classification sensed by the OCS (
page 77), the
56indicator lamp will remain illuminated or go out.
If above conditions are not met, the system is not working properly. Have the system
checked as soon as possible by an authorized Mercedes-Benz Center.
Warning!
G
If the 56indicator lamp remains
out even after performing the above correc-
tive steps, do not have any children 12 years
old and under and other small individuals
use the front passenger seat until the sys-
tem has been repaired.
