ing that the vehicle’s battery is charged,
properly connected, not damaged and mo-
bile phone and GPS coverage are available.
The speaker volume of a Tele Aid call can

!
The initial activation of the Tele Aid system
may only be performed by completing the sub-

call using the Information button¡. Failure
to complete either of these steps will result in a
system that is not activated.

The Tele Aid system utilizes the mobile
phone network for communication and the GPS
(Global Positioning System) satellites for vehicle
location. If either of these signals are unavail-
able, the Tele Aid system may not function and if
this occurs, assistance must be summoned by
other means.

710 Practical hintsTowing the vehicleMercedes-Benz recommends that the
vehicle be transported with all wheels off
the ground using flatbed or appropriate
wheel lift/dolly equipment. This method is
preferable to other types of towing.
When circumstances do not permit the
recommended towing methods, the
vehicle may be towed with all wheels on
the ground or front axle raised only so far
as necessary to have the vehicle moved to
a safe location where the recommended
towing methods can be employed.!
To prevent damage during transport, do not
tie down vehicle by its chassis or suspension
parts.
!
Before towing the vehicle observe the fol-
lowing instructions:
Do not tow-start the vehicle.
Use flatbed or wheel lift/dolly equipment
with the ignition switched off.
Do not tow with sling-type equipment. Tow-
ing with sling-type equipment over bumpy
roads will damage radiator and supports.
Towing of the vehicle should only be done
using the properly installed towing eye bolt.
Never attach a tow cable, tow rope or tow
rod to the vehicle chassis, frame or suspen-
sion parts. For more information see “Install-
ing towing eye bolt” (
page 713).
i
If the battery is disconnected or discharged
the SmartKey will not turn in the starter
switch
the automatic transmission will remain
locked in park positionP.
