Tele Aid
Important!
The initial activation of the Tele Aid system may only be
performed by completing the subscriber agreement and
placing an acquaintance call using the “SOS” button.
Failure to complete either of these steps will result in a
system that is not activated. If the system is not
activated the indicator lamp in the “SOS” button stays
on after turning electronic key in starter switch to
position 2 and the message “TELE AID – NOT
ACTIVATED” will be shown in the multifunction display
for approx. 10 seconds.
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).
(Telematic Alarm Identification on Demand)
The Tele Aid system consists of three types of response;
automatic and manual emergency, roadside assistance
and information.
The Tele Aid system is operational providing that the
vehicle’s battery is charged, properly connected, not
damaged and cellular 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, for raising press buttonæ and for
lowering press buttonç.
To activate, press the “SOS” button, the Roadside
Assistance button or t he Informa tion bu tton¡,
depending on the type of response required.
Shortly after the completion of your Acquaintance Call,
you will receive a user ID and password via first call
mail. By visiting www.mbusa.com and selecting
“Tele Aid” (USA only), you will have access to account
information, remote door unlock, Info Services
* profile
and more.
* Optional – available only with COMAND System self-check
Initially, after turning the electronic key in starter
switch to position 2, malfunctions are detected and
indicated (the indicator lamps in the “SOS” button, the
Roadside Assistance button and the Information
button¡ stay on longer than 10 seconds or do not
come on). The message “TELE AID – VISIT
WORKSHOP” appears for approx. 10 seconds in the
multifunction display.

Wa r n i n g !
When leaving the vehicle always remove the
electronic key from the steering lock, and lock the
vehicle. Do not leave children unattended in the
vehicle, or with access to an unlocked vehicle.
Unsupervised use of vehicle equipment may cause
serious personal injury.

cluster displayPractical hints Car care Index Important!
If the el ectronic key is lef t in th e steering lock position 0
for an extended period of time, it can no longer be
turned in the lock. In this case, remove electronic key
from steering lock and reinsert.
Caution!
To prevent accelerated battery discharge and a possible
dead battery, always remove the electronic key from the
steering lock. Do not leave th e ele ctronic key in steering
lock position 0.Notes:
A warning sounds when the driver’s door is opened
while the electronic key is in steering lock position 1
or 0.
With the engine at idle speed, the charging rate of the
alternator (output) is limited.
It is therefore recommended that you turn off
unnecessary electrical consumers while driving in
stop-and-go traffic. This precaution helps to avoid
draining of the battery.
Unnecessary strain on the battery and charging system
may be minimized by turning off the following power
consumers, for example:
Heated seats, rear window defroster. In addition, the
automatic climate air volume control should be set to
the lowest position.
The steering lock can only be unlocked with the vehicle
battery properly charged and connected.

Starting and turning off the engine
Before starting
Ensure that parking brake is engaged and that selector
lever is in position “P” or “N”. Turn electronic key in
steering lock to position 2.
Starting
Do not depress accelerator.
Briefly turn electronic key in steering lock clockwise to
the stop and release. The starter will engage until the
engine is running.
If engine will not run, and the starting procedure stops,
turn electronic key completely to the left and repeat
starting the engine.
After several unsuccessful attempts, have the system
checked at the nearest authorized Mercedes-Benz
Center.Important!
Due to the installed starter non-repeat feature, the
electronic key must be turned completely to the left
before attempting to start the engine again.
In areas where temperatures frequently drop below
-4°F(-20°C) we rec omm end tha t a n e ng ine bl ock h eater
be installed. Your authorized Mercedes-Benz Center will
advise you on this subject, see page 210.
Turning off
Turn t he electronic key in th e steering lock to position 0
to stop the engine.
The electronic key can only be removed with the

cluster displayPractical hints Car care Index Stopping
For brief stops, e.g. at traffic lights, leave the
transmission in gear and hold vehicle with the service
brake.
For longer stops with the engine idling, shift into “N”
or “P” and hold the vehicle with the service brake.
When stopping the vehicle on an uphill gradient, do not
hold it with the accelerator, use the brake. This avoids
unnecessary transmission heat build up.
Maneuvering
To maneuver in tight areas, e.g. when pulling into a
parking space, control the vehicle speed by gradually
releasing the brakes. Accelerate gently and never
abruptly step on the accelerator.
To rock a vehicle out of soft ground (mud or snow),
alternately shift from forward to reverse, while applying
slight partial throttle.Rocking a vehicle free in this manner may cause the
ABS or traction system malfunction indicator lamp to
come on. Turn off and restart the engine to clear the
malfunction indication.
Wa r n i n g !
Getting out of your vehicle with the selector lever
not fully engaged in position “P” is dangerous.
Also, w hen parked on an incline, posi tion “P” alone
may not prevent your vehicle from moving,
possibly hitting people or objects.Always set t he parki ng brake in addi tion to sh ifting
to position “P”, see page 202 for parking brake. When parked on an incline, also turn front wheel
against curb.Wa r n i n g !
When leaving the vehicle always remove the key
from the steering lock, and lock the vehicle. Do not
leave children unattended in the vehicle, or with
access to an u nlocked veh ic le. Ch ildren cou ld m ove
the gear selector lever from position “P”, which
could result in an accident or serious injury.

Selector lever position
The current selector lever position is indicated in the
gear range indicator display. The automatic gear
shifting process can be adapted to specific operating
conditions using the selector lever.Park position
The park position is to be used when parking the
vehicle. Engage only with the vehicle stopped.
The park position is not intended to serve as a
brake when the vehicle is parked. Rather, the
driver should always use the parking brake in
addition to placing the selector lever in park to
secure the vehicle.
Note:
The electronic key can only be removed from the
steering lock with the selector lever in
position “P”. With the electronic key removed, the
selector lever is locked in position “P”.
With a malfunction in the vehicle’s electrical
system the selector lever could remain locked in
position “P”. To unlock the selector lever
manually, see page 284.
