Checking coolant temperature G
Warning!
Driving when your engine is overheated can
cause some fluids which may have leaked into
the engine compartment to catch fire. You
could be seriously burned.
Steam from an overheated engine can cause
serious burns which can occur just by opening
the engine hood. Stay away from the engine
if you see or hear steam coming from it.
Stop the vehicle in a safe location away from
other traffic. Turn off the engine, get out of the
vehicle and do not stand near the vehicle until
the engine has cooled down.
X Press button & or * repeatedly until
the coolant temperature appears in the
multifunction display. During severe operating conditions, e.g. stop-
and-go traffic, the coolant temperature may
rise close to 248‡ (120†).
!
Excessive coolant temperature triggers a
warning in the multifunction display. The engine should not be operated with a
coolant temperature above 248‡
(120†). Doing so may cause serious
engine damage which is not covered by the
Mercedes-Benz Limited Warranty.
Calling up digital speedometer or
outside temperature You can select whether the digital
speedometer or the outside temperature
appears in the multifunction display
(Y page 104).
G
Warning!
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Indicated temperatures just above the
freezing point do not guarantee that the road
surface is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
X Press button & or * repeatedly until
the digital speedometer or the outside
temperature appears in the multifunction
display. Digital speedometer
AMG menu

transmitter button ( ;, = or ?). Do not
release the button.
Indicator lamp : will begin to flash after
20 seconds.
X Without releasing the signal transmitter
button,
proceed with programming starting
with step 3.
Operation of integrated remote control X
Switch on the ignition.
X Select and press the appropriate
integrated signal transmitter button ( ;,
=

or ?) to activate the remote controlled
device.
The integrated remote control transmitter
continues to send the signal as long as the
button is pressed – up to 20 seconds.
Erasing the integrated remote control
memory i
If
you sell your vehicle, erase the codes of
all three channels.
X Switch on the ignition.
X Simultaneously press and hold outer signal
transmitter buttons ; and ?, for
approximately 20 seconds, until indicator
lamp : flashes rapidly. Do not hold for
longer than 30 seconds.
The

codes of all three channels are erased.
Programming tips If you are having difficulty programming the
integrated remote control, here are some
helpful tips:
R
Check the frequency of hand-held remote
control A

(typically located on the reverse
side of the remote). The integrated remote control is compatible with radio-frequency
devices operating between 280-390 MHz

.
R Put a new battery in hand-held remote
control A. This will increase the likelihood
of the hand-held remote control sending a
stronger and more accurate signal to the
integrated remote control.
R While performing step 3, hold hand-held
remote control A at different lengths and
angles from the signal transmitter button
(;, = or ?) you are programming.
Attempt varying angles at the distance of 2
to 12 inches (5 to 30 cm) away or the same
angle at varying distances.
R If another hand-held remote control is
available for the same device, try the
programming steps again using that other
hand-held remote control. Make sure new
batteries are in the hand-held remote
control before beginning the procedure.
R Straighten the antenna wire from the
garage door opener assembly. This may
help improve transmitting and/or receiving
signals.
i Certain types of garage door openers are
incompatible with the integrated remote
control. If you should experience further
difficulties with programming the
integrated remote control, contact an
authorized Mercedes-Benz Center, or call
the Mercedes-Benz Customer Assistance
Center (USA only) at
1-800-FOR-MERCedes, or the HomeLink ®
Hotline (USA only) at 1-800-355-3515, or
the Customer Service (Canada only) at
1-800-387-0100. 186

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.
Opening G
Warning!
Do not open the hood when the engine is
overheated. You could be seriously injured.
Observe the coolant temperature display to
determine whether the engine may be
overheated. If you see flames or smoke
coming from the engine compartment, move
away from the vehicle. Wait until the engine
has cooled. If necessary, call the fire
department. G
Warning!
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 completely
before touching any components on the
vehicle. Comply with all relevant safety
precautions. G
Warning!
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.

The amount of oil your engine consumes will
depend on a number of factors, including
driving style. Increased oil consumption can
occur when the vehicle is new or the vehicle
is driven frequently at higher engine speeds. Engine oil consumption checks should only
be made after the vehicle break-in period.
!
Do not use any special lubricant additives,
as these may damage the drive assemblies.
Using special additives not approved by
Mercedes-Benz may cause damage not
covered by the Mercedes-Benz Limited
Warranty.
For further information contact an
authorized Mercedes-Benz Center.

Coolant level
The engine coolant is a mixture of water and
anticorrosion/antifreeze.
When checking the coolant level, the vehicle
must be parked on level ground, and the
coolant temperature must be below 158‡
(70†). G
Warning!
In order to avoid any potentially serious burns:
R Use extreme caution when opening the
hood if there are any signs of steam or
coolant leaking from the cooling system, or
if the coolant temperature display indicates
that the coolant is overheated.
R Do not remove the cap on the coolant
expansion tank if the coolant temperature
is above 158‡ (70†). Allow the engine to
cool down before removing the cap. The
coolant expansion tank contains hot fluid
and is under pressure.
R Using a rag, slowly open the cap
approximately 1
/ 2 turn counterclockwise
to relieve excess pressure. If opened
immediately, scalding hot fluid and steam
will be blown out under pressure.
R Do not spill antifreeze on hot engine parts.
Antifreeze contains ethylene glycol which
may burn if it comes into contact with hot
engine parts. Example illustration: SLK 350
X
Using a rag, slowly open cap ;
approximately 1
/ 2 turn counterclockwise
to relieve excess pressure.
X Continue turning cap ; counterclockwise
and remove it.

Do not allow cleaning agents to dry on the
finish.
Automatic car wash
You can have your vehicle washed in an
automatic
car wash from the start. Brushless
car washes are preferable.
X To protect the filter system, activate the air
recirculation mode using button g on
the climate control panel.
! Do
not clean your vehicle in an automatic
touchless car wash which uses caustic
spray. Caustic spray will damage the paint
or ornamental moldings.
If the vehicle is very dirty, prewash it before
running it through the automatic car wash.
! Make sure the combination switch is set
to wiper setting 0. Otherwise, the rain
sensor could activate and cause the wipers
to move unintentionally. This may lead to
vehicle damage.
Due to the width of the vehicle, fold in
exterior rear view mirrors prior to running
the vehicle through an automatic car wash
to prevent damage to the mirrors.
Vehicles with automatic transmission:
X When taking the vehicle through an
automatic conveyor-type car wash:
Make sure the automatic transmission
remains in neutral position N.
When leaving the automatic car wash, make
sure the mirrors are folded out.
After running the vehicle through an
automatic car wash, wipe any wax off of the
windshield and the wiper blade inserts. This
will prevent smears and reduce wiping noise
which can be caused by residual wax on the
windshield.
Ornamental moldings X
For regular cleaning and care of ornamental
moldings, use a damp cloth. !
Do
not use chrome cleaner on ornamental
moldings. Although ornamental moldings
may have chrome appearance, they could
be made of anodized aluminum that will be
damaged when cleaned with chrome
cleaner. Instead, use a damp cloth to clean
those ornamental moldings.
For very dirty ornamental moldings of
which you are sure are chrome-plated, use
a chrome cleaner. If in doubt whether an
ornamental molding is chrome-plated,
contact an authorized Mercedes-Benz
Center.
Headlamps, brake lamps, tail lamps,
side markers, turn signal lenses X
Use a mild vehicle wash detergent, such as
Mercedes-Benz approved Car Shampoo,
with plenty of water.
! Only use window cleaning solutions that
are suitable for plastic lamp lenses.
Window cleaning solutions which are not
suitable may damage the plastic lamp
lenses

of the headlamps. Therefore, do not
use abrasives, solvents or cleaners that
contain solvents.
Cleaning the windows and the wiper
blades !
The windshield wipers must be in a
vertical position before folding them away
from the windshield. They could otherwise
damage the hood.
Never

open the hood when the wiper arms
are folded forward.
X Make sure the hood is fully closed.
X Switch on the ignition.
X Turn combination switch to wiper setting
II (Y page 76).
X With wiper arms in vertical position, switch
