Programming the integrated remote
control
Step 1:
Switch on the ignition (page 37).Step 2:
If you have previously programmed a
signal transmitter button and wish to
retain its programming, proceed to
step 3.
If you are programming the integrated
remote control for the first time, press
and hold the two outer signal transmit-
ter buttons2 and4 and release
them only when indicator lamp1
begins to flash after approximately
20 seconds (do not hold the button for
longer than 30 seconds). This proce-
dure erases any previous settings for
all three channels and initializes the
memory.
If you later wish to program a second
and/or third hand-held transmitter to
the remaining two signal transmitter
buttons, do not repeat this step and
begin directly with step 3.Step 3:Hold the end of hand-held remote
control5 of the device you wish
to train approximately
2 to 5 in (5 to12 cm) away from the
signal transmitter button (2, 3 or4)
to be programmed, while keeping indi-
cator lamp1 in view.
Step 4:
Using both hands, simultaneously
press hand-held remote control
button6 and the desired signal trans-
mitter button (2, 3 or4). Do not
release the buttons until step 5 is com-
pleted.
Indicator lamp1 will flash, first slowly
and then rapidly.
When programming a garage door opener, it
is advised to park outside the garage.
Do not run the engine while programming
the integrated remote control. Inhalation of
exhaust gas is hazardous to your health.
All exhaust gas contains carbon monoxide
(CO), and inhaling it can cause unconscious-
ness and possible death.
iIndicator lamp1 flashes immediately the
first time the signal transmitter button is pro-
grammed. If this button has already been pro-
grammed, the indicator lamp will only start
flashing after 20 seconds.

Reprogramming a single signal trans-
mitter button
To program a device using a signal trans-
mitter button previously trained, follow
these steps:
Switch on the ignition (page 37).
Press and hold the desired signal
transmitter button (2, 3 or4).
Do not release the button.
Indicator lamp1 will begin to flash
after 20 seconds. Without releasing
the signal transmitter button, proceed
with programming starting with step 3.Operation of integrated remote control
Switch on the ignition (page 37).
Select and press the appropriate inte-
grated signal transmitter button (2,
3 or4) to activate the remote con-
trolled device.
The integrated remote control trans-
mitter continues to send the signal as
long as the button is pressed – up to
20 seconds.Erasing the integrated remote control
memorySwitch on the ignition (page 37).
Simultaneously press and hold outer
signal transmitter buttons2 and 4,
for approximately 20 seconds, until
indicator lamp1 flashes rapidly. Do
not hold for longer than 30 seconds.
The codes of all three channels are
erased.
iIf you sell your vehicle, erase the codes of all
three channels.

294 Operation
Engine compartment
Hood
Opening
1Hood lock release lever
Warning!G
Do not pull the release lever while the vehi-
cle is in motion. Otherwise the hood could
be forced open by passing air flow.
This could cause the hood to come loose
and injure you and/or others.
Warning!G
If you see flames or smoke coming from the
engine compartment, or if the coolant tem-
perature gauge indicates that the engine is
overheated, do not open the hood. Move
away from the vehicle and do not open the
hood until the engine has cooled. If neces-
sary, call the fire department.
Warning!G
You could be injured when the hood is open
– even when the engine is turned off.
Parts of the engine can become very hot. To
prevent burns, let the engine cool off com-
pletely before touching any components on
the vehicle. Comply with all relevant safety
precautions.
Warning!G
To help prevent personal injury, stay clear of
moving parts when the hood is open and the
engine is running.
The radiator fan may continue to run for
approximately 30 seconds or may even
restart after the engine has been turned off.
Stay clear of fan blades.
Warning!G
The engine is equipped with a transistorized
ignition system. Because of the high voltage
it is dangerous to touch any components
(ignition coils, spark plug sockets,
diagnostic socket) of the ignition system

with the engine running

while starting the engine

if ignition is “on” and the engine is
turned manually

296 Operation
Engine compartment
Engine oil
The amount of oil your engine needs will
depend on a number of factors, including
driving style. Higher oil consumption can
occur when

the vehicle is new

the vehicle is driven frequently at
higher engine speeds
Engine oil consumption checks should only
be made after the vehicle break-in period.Checking engine oil level with the
control system (SLK 55 AMG only)
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, the vehicle must have been
stationary for at least 30 minutes with
the engine turned off.To check the engine oil level via the
multifunction display, do the following:
Switch on the ignition (page 37).
The standard display appears in the
multifunction display (
page 127).
Press buttonk orj on the mul-
tifunction steering wheel repeatedly
until the following message appears in
the multifunction display (
page 122):
!Do not use any special lubricant additives,
as these may damage the drive assemblies.

316 Operation
Tires and wheels
Restarting the Run Flat Indicator
The tire inflation pressure monitor must be
restarted in the following situations:

If you have changed the tire inflation
pressure

If you have replaced the wheels or tires

If you have installed new wheels or
tires
Using the Tire and Loading Information
placard on the driver’s door B-pillar or,
if available, the tire inflation pressure
label on the inside of the fuel filler flap,
make sure the tire inflation pressure of
all four tires is correct.
Switch on the ignition (page 37).
The standard display menu appears in
the multifunction display (
page 127).
Press buttonk orj repeatedly
until the following message appears in
the multifunction display:
Run Flat Indicator

After a certain “learning phase”, the Run
Flat Indicator checks the set pressure
values for all four tires.
If you wish to cancel activation:
Press buttonç.
or
Wait until the message
Restart
Run Flat Indicator?
disappears.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.

319 Operation
Tires and wheels
Tire inflation pressure warnings
If the system detects a significant loss of
tire inflation pressure in one or more than
one tire, a message appears in the multi-
function display.
Example illustration
In addition, a warning signal sounds.Restarting the TPMS
The TPMS must be restarted when you
have adjusted the tire inflation pressure to
a new level (e.g. because of different load
or driving conditions). The TPMS is then
recalibrated to the current tire inflation
pressures.
Using the Tire and Loading Information
placard on the driver’s door B-pillar
(
page 307) or, if available, the
supplemental tire inflation pressure
information on the inside of the fuel
filler flap (
page 291), make sure the
tire inflation pressure of all four tires is
correct.
Switch on the ignition (page 37).
Press buttonè orÿ on the
multifunction steering wheel repeat-
edly until the standard display menu
appears in the multifunction
display (
page 127).
Press button j ork repeatedly
until the following message appears in
the multifunction display:
Tire Pressure Monitor
Active
Menu: R-Button
Warning!G
It is the driver’s responsibility to calibrate
the TPMS on the recommended cold infla-
tion pressure. Underinflated tires affect the
ability to steer or brake the vehicle. You
might lose control over the vehicle.
iRestart the TPMS after adjusting the tire in-
flation pressure to the inflation pressure recom-
mended for the vehicle operating condition. Tire
pressure should only be adjusted on cold tires.
Observe the recommended tire inflation pres-
sure on the Tire and Loading Information placard
on the driver’s door B-pillar (
page 307). Some
vehicles may have supplemental tire inflation
pressure information for driving at high speeds
(
page 313) or for vehicle loads less than the
maximum loaded vehicle condition
(
page 313). If such information is provided, it
can be found on the inside of the fuel filler flap.
