The Tele Aid* system
(Tele
matic Alarm Identification on
D
emand)
The Tele Aid system consists of three
types of response:
Automatic and manual emergency
Roadside Assistance
Information
The Tele Aid system is operational provid-
ing that the vehicle’s battery is charged,
properly connected, not damaged and cel-
lular and GPS coverage is available.
The speaker volume of a Tele Aid call can
be adjusted when using the volume control
on the multifunction steering wheel. To
raise, press buttonæ and to lower,
press buttonç or use the volume knob
on your audio system or COMAND* head
unit.
To activate, press the SOS button, the
Roadside Assistance button• or
the Information button¡, depend-
ing on the type of response required.
iThe SOS button is located in the overhead
control panel.
The Roadside Assistance button•
(
page 265) and the Information button¡
(
page 267) are located below the center
armrest cover.
!The Tele Aid system utilizes the cellular net-
work for communication and the GPS (Global
Positioning System) satellites for vehicle loca-
tion. 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.
iWhen a Tele Aid call has been initiated, the
audio system or COMAND* system audio is mut-
ed and the selected mode (radio, tape or CD)
pauses. The optional cellular phone* (if installed)
and inserted in cradle switches off. If you must
use this phone, we recommend that you use it
only with the vehicle at a standstill in a safe loca-
tion. Remove the phone from the cradle and
place the call. The COMAND* navigation system
(if engaged) will continue to run. The display in
the instrument cluster is available for use, and
spoken commands are only available by pressing
the RPT button on the COMAND* unit. A pop-up
window will appear in the COMAND* display to
indicate that a Tele Aid call is in progress. After
the Tele Aid call has ended, the optional cellular
phone switches on again. A PIN entry might be
necessary.
281 Operation
Driving instructions
Refer to the description of the Brake Assist
System (BAS) (
page 86).
Brake pad wear or a leak in the system may
be the reason for low brake fluid in the res-
ervoir.
The brake fluid level in the reservoir may
be too low if the brake warning lamp in
the instrument cluster (
page 26)
comes on although the parking brake is
released (
page 348). Observe additional
messages that may appear in the multi-
function display (
page 367).
Have the brake system inspected immedi-
ately. Contact an authorized
Mercedes-Benz Center.All checks and service work on the brake
system should be carried out by qualified
technicians only. Contact an authorized
Mercedes-Benz Center.
Install only brake pads and brake fluid
recommended by Mercedes-Benz.
After hard braking, it is advisable to drive
on for some time, rather than immediately
park, so that the air stream will cool down
the brakes faster.High-performance brake system
(SLK 55 AMG only)
The high-performance brake system is de-
signed to operate under the extremely high
operating demands required to accommo-
date the performance capabilities of the
vehicle. The brakes may produce a squeak-
ing-type noise depending on the
vehicle speed
brake force applied
ambient conditions, e.g. temperature
and humidity
As with any brake system, the wear of indi-
vidual brake system components such as
brake pads or discs strongly depends on
your driving style and the conditions under
which you operate the vehicle. Thus, a driv-
ing style calling for high demand braking
will cause your vehicle’s brakes to wear
more quickly.
Warning!G
Make sure not to endanger any other road
users when carrying out these braking
maneuvers.
Warning!G
If other than recommended brake pads are
installed, or other than recommended brake
fluid is used, the braking properties of the
vehicle can be degraded to an extent that
safe braking is substantially impaired. This
could result in an accident.
!When driving down long and steep grades,
relieve the load on the brakes by shifting into a
lower gear to use the engine’s braking power.
This helps prevent overheating of the brakes and
reduces brake pad wear.
282 Operation
Driving instructions
Driving off
Apply the brakes to test them briefly after
driving off. Perform this procedure only
when the road is clear of other traffic.
Warm up the engine smoothly. Do not
place full load on the engine until the oper-
ating temperature has been reached.Parking
Warning!G
New vehicle brake pads and discs, and
replacement brake pads and discs may take
several hundred miles of driving until they
provide optimum braking efficiency. Until
that time, you may need to use increased
brake pedal pressure while braking. Please
be aware of this and adjust your driving and
braking accordingly during this break-in
period.
Excessive high demand braking will cause
correspondingly high brake wear. Please be
attentive to the brake warning lamp in the
instrument cluster and brake condition mes-
sages in the multifunction display. Especial-
ly for high performance driving, it is
important to maintain the brake system and
have it checked regularly.
!When starting off on a slippery surface, do
not allow a drive wheel to spin for an extended
period with the ESP
® switched off. Doing so may
cause serious damage to the drivetrain which is
not covered by the Mercedes-Benz Limited
Warranty.
!Simultaneously depressing the accelerator
pedal and applying the brake reduces engine
performance and causes premature brake and
drivetrain wear.
Warning!G
Do not park this vehicle in areas where
combustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.
To reduce the risk of personal injury or
damage to the vehicle drivetrain as a result
of vehicle movement, before turning off the
engine and leaving the vehicle always:
Keep right foot on brake pedal.
Pull the parking brake lever up as many
notches as possible.
Manual transmission: Move the gear-
shift lever into first or reverse gear.
Automatic transmission*: Move the
gear selector lever to position P.
