Information
The Tele Aid system is operational provid-
ing that the vehicle’s battery is charged,
properly connected, not damaged and
cellular and GPS coverage is available.
The Tele Aid system utilizes the cellular
network for communication and the GPS
(Global P
ositioning S
ystem) satellites for
vehicle location. If either of these signals
are unavailable, the Tele Aid system may
not function and if this occurs, assistance
must be summoned by other means.
!
In order to activate the Tele Aid system, a
subscriber agreement must be completed. To
ensure your system is activated and operational,
please press the ¡button to perform the ac-
quaintance call. Failure to complete either of
these steps may result in a system that is not ac-
tivated.
If you have any questions regarding activation,
please call the Response Center at
1-800-756-9018 (in the USA) or
1-888-923-8367 (in Canada).

Location of the vehicle on a map is only pos-
sible if the vehicle is able to receive signals from
the GPS satellite network and pass the informa-
tion on to the Response Center.

226 Controls in detailUseful featuresProgramming tips
If you are having difficulty programming
the integrated remote control, here are
some helpful tips:

Check the frequency of the hand-held
remote control5 (typically located on
the reverse side of the remote). The in-
tegrated remote control is compatible
with radio-frequency devices operating
between 280-390 MHz.


Put a new battery in hand-held remote
control5. This will increase the likeli-
hood of the hand-held remote control
sending a faster and more accurate sig-
nal to the integrated remote control.


While performing step 3, hold
hand-held remote control5 at differ-
ent lengths and angles from the signal
transmitter button (2, 3 or4) you
are programming. Attempt varying
angles at the distance of 2 to 5 in
(5 to 12 cm) away or the same angle at
varying distances.


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.


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 in-
compatible 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 Mercedes-Benz Customer Assistance
Center (in the USA) at 1-800-FOR-MERCedes, or
Customer Service (in Canada) at
1-800-387-0100.

ciently charged in order to achieve its rat-
ed service life. A flat battery must be fully
recharged. Refer to Maintenance Booklet
for battery maintenance intervals.
If you use your vehicle mostly for
short-distance trips, you will need to have
the battery charge checked more
frequently.
When replacing batteries, always use bat-
teries approved by Mercedes-Benz. Have
this work only carried out by an authorized
Mercedes-Benz Center.
If you do not intend to operate your vehicle
for an extended period of time, consult an
authorized Mercedes-Benz Center about
steps you need to observe.For more information on battery mainte-
nance, see “Batteries” (

292 OperationWinter drivingBefore the onset of winter, have your
vehicle winterized at an authorized
Mercedes-Benz Center. This service
includes:

Check of anticorrosion and antifreeze
concentration.


Addition of cleaning concentrate to the
water of the windshield and headlamp
cleaning system. Add MB Concentrate
“MB Summerfit” to a premixed wind-
shield washer solvent/antifreeze
which is formulated for below freezing
temperatures (
page 401).


Battery test. Battery capacity drops
with decreasing ambient temperature.
A well charged battery helps to make
sure that the engine can be started,
even at low ambient temperatures.


Tire change. Mercedes-Benz recom-
mends M+S rated radial-ply tires with a
minimum tread depth of approximately 1/6in (4 mm) on all four wheels for the
winter season.
Winter tires*
Always use winter tires at temperatures
below 45°F (7°C) and whenever wintry
road conditions prevail. Not all M+S rated
tires provide special winter performance.
Make sure the tires you use show the
mountain/snowflake.marking on the
tire sidewall. These tires meet specific
snow traction performance requirements
of the Rubber Manufacturers Association
(RMA) and the Rubber Association of Can-
ada (RAC) and have been designed specif-
ically for use in snow conditions. Use of
winter tires is the only way to achieve the
maximum effectiveness of the ABS and
ESP
® in winter operation.
For safe handling, make sure that all
mounted winter tires are of the same make
and have the same tread design.Always observe the speed rating of the
winter tires installed on your vehicle. If the
maximum speed for which your tires are
rated is below the speed rating of your
vehicle, you must place a notice to this
effect where it will be seen by the driver.
Such notices are available from your tire
dealer or from any authorized
Mercedes-Benz Center.
After you have fitted the winter tires,
restart the TPMS (
page 274).
!
A wheel change should only be carried out
at an authorized Mercedes-Benz Center. Other-
wise there is a danger of damaging the vehicle by
jacking it up incorrectly.
Warning!
G
Winter tires with a tread depth of less than 1/6in (4 mm) must be replaced. They are no
longer suitable for winter operation, in par-
ticular because they do not provide suffi-
cient grip. This could cause you to lose
control of your vehicle and cause an acci-
dent.

If the vehicle is not be used for a longer pe-
riod of time, do not disconnect the consumer
battery. Instead, maintain the condition of the
battery by using the battery charger approved by
Mercedes-Benz for use on the SLR and supplied
with the car (
page 372). This charger automat-
ically controls the charge rate, and can be left
connected to the car for long periods without
damage to the battery.
If the battery supplying the vehicle’s electrical
consumers is disconnected, the days of discon-
nection will not be included in the count shown
by the maintenance service indicator. To arrive
at the true maintenance service deadline, you
will need to subtract these days from the days
shown in the maintenance service indicator.
Do not confuse the maintenance service indica-
tor with the engine oil level indicator:.

Suggested solutions
-
The yellow ABS indicator
lamp comes on while the
engine is running.
Risk of accident!
The ABS has detected a malfunction and
has switched off. The BAS and the ESP
®
are also switched off.
If the ABS control unit is malfunctioning,
other systems such as the automatic
transmission may also be malfunctioning.
The electro-hydraulic brake system is still
functioning normally but without ABS
available.

Continue driving with added caution. Wheels
may lock during hard braking, reducing
steering capability.

Have the system checked at an authorized
Mercedes-Benz Center immediately.
Failure to follow these instructions increases
the risk of an accident.

Read and observe messages in the
multifunction display (
page 319).
The charging voltage has fallen below
10 volts. The ABS has switched off.
The battery may not be charged
sufficiently.
When the voltage is above this value again, the
ABS is operational again and the ABS indicator
lamp should go out.
If the ABS indicator lamp does not go out:
Have the generator (alternator) and the
battery checked.
