cluster displayPractical hints Car care Index KEYLESS-GO-card
The KEYLESS-GO-card (1) does not have a removable
mechanical key.
The functions of the KEYLESS-GO-card (1) are identical
to those of the electronic main key. Carrying the card
with you permits the use of the vehicle.The validity of the KEYLESS-GO-card is checked every
time when grasping a door handle or pushing the trunk
lid release. Once the KEYLESS-GO-card is recognized
outside the vehicle, the doors, trunk lid and fuel filler
flap are unlocked, depending on the selected mode
(global or selective unlocking mode, see page 43).
Starter switch KEYLESS-GO, see page 228.
Starting and turning off the engine with KEYLESS-GO,
see page 231 and page 232.
Note:
In the case of a malfunction in the KEYLESS-GO-system,
we recommend that you carry the electronic key plus
mechanical key with you and keep them in a safe place
so that they are always handy. Never leave the electronic
key or a KEYLESS-GO-card in the vehicle.
Obtaining replacement keys
Your vehicle is equipped with a theft deterrent locking
system requiring a special key manufacturing process.
For security reasons, replacement keys can only be
obtained from your authorized Mercedes-Benz Center.

cluster displayPractical hints Car care Index General notes on the central locking system
If the electronic key is inserted in the starter switch, the
vehicle cannot be locked or unlocked with the remote
control.
If the vehicle cannot be locked or unlocked:
•Aim transmitter eye at a receiver on either front
door handle. Check the batteries of the electronic
main key, see page 363, or synchronize the remote
control, see page 365.
•Use the mechanical key to unlock the vehicle. To
start engine, insert the electronic key in the starter
switch. There could be a slight delay until the
electronic key can be turned in the starter switch.
•Vehicles with KEYLESS-GO only:
A KEYLESS-GO-card must be recognized by the
system as being outside the vehicle to enable the
vehicle to be locked or unlocked (maximum distance
between card and doors or trunk is approx. 3 ft.
(1 m). Check the location of the KEYLESS-GO-card,
see page 38. Check the batteries of the KEYLESS-
GO-card, see page 366. The trunk lid will open
automatically if a KEYLESS-GO card is detected in
the trunk, see page 38.Note:
If neither the remote control nor KEYLESS-GO system
functions, use the mechanical key to unlock or lock the
vehicle. To start engine, insert the electronic key in the
starter switch. There could be a slight delay until the
electronic key can be turned in the starter switch.
Important!
When unlocking the driver’s door with the mechanical
key, the exterior lamps will flash and the alarm will
sound.
To cancel the alarm, insert the electronic key in the
starter switch, or press buttonŒ or‹ on the
electronic main key; or with the optional KEYLESS-GO-
system, when carrying a KEYLESS-GO-card, by grasping
a door handle or pressing the start- / stop button on the
gear selector lever.

Te ch n ica l
data Instruments
and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index Notes:
Following a tire inflation pressure reactivation process
the real tire inflation pressures are displayed only after
a few minutes travel time.
Possible differences between readings of a tire pressure
gauge of an air hose, e.g. gas station equipment, and the
vehicle’s multifunction display can occur. The vehicle’s
multifunction display of the tire inflation pressure
monitor is a more precise reading.Activation of tire inflation pressure monitor
Activation of tire inflation pressure monitor is
necessary if tire inf lation pressure is being changed,
wheels or tires are replaced, or new wheels are installed
on the vehicle.
Tire inf lation pressure should be checked and corrected
according to the label affixed inside the fuel filler flap.
For a detailed description, refer to page 348.
Turn electronic key in starter switch to position 2 (the
engine must not be running).
Notes:
When checking the tire inflation pressure of the road
wheels, also check the spare tire.
The tire inflation pressure of the spare wheel, mounted
or not mounted, is not monitored by the tire inflation
pressure monitor.
See page 338 for location of the spare wheel, and
page 348 for tire inflation pressure.

Engine oil level indicator
To check the engine oil level, park vehicle on level
ground, with engine at normal operational temperature.
Check oil level approximately 5 minutes after stopping
the engine, allowing for the oil to return to the oil pan.
The message “PERF. SERV. ON TIME” (perform service
[engine oil level check] on time) will be displayed if the
required waiting period has not been observed after
stopping the engine:
•with engine at operational temperature
approximately 5 minutes.•with engine not at operational temperature up to
approximately 30 minutes.
The engine oil level check can be repeated after a short
time.
Turn the electronic key in starter switch to position 2.
To call up the trip odometer and main odometer, press
button è or ÿ on the multifunction steering
wheel until the display appears. See page 124.
Press button j or k on the multifunction
steering wheel repeatedly until the “MEASUREMENT
CORRECT – ONLY IF VEH. LEVEL” engine oil level
indicator appears. This indicator is only a reminder.
Measurement can be cancelled by pressing button j
or k if the vehicle is not parked on level ground. An
incorrect reading will be recorded if you do not cancel
the measurement. Move the vehicle to level ground and
measure again.
The electronic key in starter switch is not in position 2 if
the “ENGINE OIL LEVEL – SWITCH ON IGNITION”
message appears.
The “ENGINE OIL LEVEL – MEASURING NOW”
message is displayed after approximately 3 seconds.

on the indicator:
“ENGINE OIL LEVEL – O.K.”
No oil needs to be added.
“ENGINE OIL LEVEL – ADD 1.0 QUART”
(Canada: 1.0 L)
“ENGINE OIL LEVEL – ADD 1.5 QUART”
(Canada: 1.5 L)
“ENGINE OIL LEVEL – ADD 2.0 QUART”
(Canada: 2.0 L)
See “Checking engine oil level”, on page 334 for
instructions on adding engine oil.
“ENGINE OIL LEVEL – REDUCE OIL LEVEL”
Do not overfill the engine.
Excessive oil must be siphoned or drained off. It could
cause damage to the engine and catalytic converter not
covered by the Mercedes-Benz Limited Warranty.
The “MEASURING NOT POSSIBLE” message will be
displayed if a proper oil level check cannot be
performed. The engine oil level check can be repeated
after a short while.S 430, S 500 and S 55 AMG only:
Perform the engine oil level check with the dipstick, if it
cannot be completed via the multifunction display.
See “Checking engine oil level”, page 334.
In this case we recommend that you have the system
checked at a Mercedes-Benz Center.
Notes:
See malfunction and warning messages on page 303
and page 318 if an engine oil level indicator appears in
the multifunction display when the engine is running.
The engine oil level cannot be checked while the engine
is running. The “ENGINE OIL LEVEL – NOT WHEN
ENGINE ON” message will appear.
Engine oil consumption
Engine oil consumption checks should only be made
after the break-in period. During the break-in period,
higher oil consumption may be noticed and is normal.
Frequent driving at high engine speeds results in
increased consumption.

167 Automatic climate control
Te ch n ica l
data Instruments
and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index Automatic climate control
The system is always at operational readiness, except
when manually switched off.
The automatic climate control only operates with the
engine running.
The temperature selector should be left at the desired
temperature setting. The temperature selected is
reached as quickly as possible.
Th e system w il l not hea t or c ool a ny q uicker by setting a
higher or lower temperature.
The desired interior temperature and air distribution
can be selected separately for the left and right side of
the passenger compartment.
The automatic climate control removes considerable
moisture from the air during operation in the cooling
mode. It is normal for water to drip on the ground
through ducts in the underbody.
The air conditioning will not engage (no cooling) if the
economy mode S is selected, see page 173. Notes:
Do not obstruct the air flow by placing objects on the air
flow-through exhaust slots below the rear window.
Also keep the air intake grill in front of the windshield
free of snow and debris.
The storage compartment between the front seats can be
ventilated. See page 175 for notes on ventilating the
storage space under the armrest in the center console.
The air conditioner switches itself off for its own
protection if refrigerant is lost. No cooling will then take
place. Economy mode S cannot be switched off. Have
the air conditioner checked by a Mercedes-Benz Center
should this happen.
Dust filter
Nearly all dust particles and pollen are filtered out
before outside air enters the passenger compartment
through the air distribution system.
