Once the tow-away alarm is armed, a visual
and audible alarm will be triggered when
someone attempts to raise the vehicle.Arming the tow-away alarm
Lock the vehicle with the SmartKey.
The tow-away alarm is automatically
armed after about 30 seconds.
Disarming the tow-away alarm
To prevent triggering the tow-away alarm,
switch off the tow-away alarm feature
before towing the vehicle, or when parking
on a surface subject to movement, such as
a ferry or auto train.
i
The alarm system will rearm automati-
cally after approximately 40 seconds if
neither a door nor the trunk lid was
opened.i
If the alarm stays on for more than
30 seconds, a call to the Response
Center is initiated automatically by the
Tele Aid system* (

ed Tele Aid service was subscribed to
and properly activated, and that neces-
sary cellular service and GPS coverage
are available.

269 Controls in detail
Useful features
The Mercedes-Benz Roadside Assistance
dispatcher will either dispatch a qualified
Mercedes-Benz technician or arrange to
tow your vehicle to the nearest
Mercedes-Benz Center. For services such
as labor and/or towing, charges may ap-
ply. Refer to the Roadside Assistance Man-
ual for more information.
These programs are only available in the
USA:
Sign and Drive services: Services such
as jump start, a few gallons of fuel or
the replacement of a flat tire with the
vehicle spare tire are obtainable.
i
The indicator lamp on the Roadside
Assistance button• remains illumi-
nated in red for approximately
10 seconds during the system
self-check after switching on the igni-
tion (together with the SOS button and
the Information button¡).
See system self-check (
page 266) if
the indicator lamp does not come on in
red or stays on longer than
approximately 10 seconds.
If the indicator lamp on the Roadside
Assistance button• is flashing
continuously and there was no voice
connection to the Response Center
established, then the Tele Aid system
could not initiate a Roadside Assis-
tance call (e.g. the relevant cellular
phone network was not available). The
message
Call failed appears in the
multifunction display.
Roadside Assistance calls can be
terminated using thet button on
the multifunction steering wheel or the
END Button on the audio system or
COMAND* System.
312 Operation
Tires and wheels
Step 6 (if applicable)
If your vehicle will be towing a trailer,
load from your trailer will be trans-
ferred to your vehicle. Consult this
manual to determine how this reduces
the available cargo and luggage load
capacity of your vehicle (
page 314).
The following table shows examples on
how to calculate total and cargo load
capacities with varying seating configura-
tions and number and size of occupants.
The following examples use a load limit
of 1500 lbs. This is for illustration
purposes only. Make sure you are using
the actual load limit for your vehicle stated
on the vehicle’s placard (
page 309).
314 Operation
Tires and wheels
Certification label
Even after careful determination of the
combined weight of all occupants, cargo
and the trailer tongue load (if applicable)
(
page 314) as to not exceed the permis-
sible load limit, you must make sure that
your vehicle never exceeds the Gross Vehi-
cle Weight Rating (GVWR) and the Gross
Axle Weight Rating (GAWR) for either the
front or rear axle. You can obtain the
GVWR and GAWR from the Certification la-
bel. The Certification Label can be found
on the driver’s door B-pillar, see “Technical
data” (
page 426).Gross Vehicle Weight Rating (GVWR): The
total weight of the vehicle, all occupants,
all cargo, and the trailer tongue load
(
page 314) must never exceed the
GVWR.
Gross Axle Weight Rating (GAWR): The to-
tal allowable weight that can be carried by
a single axle (front or rear).
To assure that your vehicle does not ex-
ceed the maximum permissible weight
limits (GVWR and GAWR for front and rear
axle), have the loaded vehicle (including
driver, passengers and all cargo and, if ap-
plicable, trailer fully loaded) weighed on a
suitable commercial scale.Trailer tongue load
The tongue load of any trailer is an impor-
tant weight to measure because it affects
the load you can carry in your vehicle. If a
trailer is towed, the tongue load must be
added to the weight of all occupants riding
and any cargo you are carrying in the
vehicle. The tongue load typically is ten
percent of the trailer weight and every-
thing loaded in it.
Your Mercedes-Benz has been designed
primarily to carry passengers and their
cargo. Mercedes-Benz does not recom-
mend trailer towing with your vehicle.

Storage position
Turn crank handle in the direction of ar-
row as far as it will go.
Warning!G
The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into both sides of the vehicle. To help
avoid personal injury, use the jack only to lift
the vehicle during a wheel change. Never
get beneath the vehicle while it is supported
by the jack. Keep hands and feet away from
the area under the lifted vehicle. Always
firmly set parking brake and block wheels
before raising vehicle with jack.
Do not disengage parking brake while the
vehicle is raised. Be certain that the jack is
always vertical (plumb line) when in use,
especially on hills. Always try to use the jack
on level surface. Make sure the jack arm is
fully seated in the jack take-up bracket.
Always lower the vehicle onto sufficient
capacity jackstands before working under
the vehicle.
