Roadside Assistance button•
The Roadside Assistance button• is
located below the center armrest cover.
Open the storage compartment under
the center armrest (
page 244).
Press and hold button (for longer than
2 seconds).
A call to a Mercedes-Benz Roadside
Assistance dispatcher will be initiated.
The button will flash while the call is in
progress. The message
Connecting call
will appear in the
multifunction display.
When the connection is established, the
message
Call connected
appears in the
multifunction display. The Tele Aid system
will transmit data generating the vehicle
identification number, model, color and
location (subject to availability of cellular
and GPS signals).A voice connection between the Roadside
Assistance dispatcher and the occupants
of the vehicle will be established.
Describe the nature of the need for
assistance.
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.
Warning!
G
If you feel at any way in jeopardy when in the
vehicle (e.g. smoke or fire in the vehicle,
vehicle in a dangerous road location), please
do not wait for voice contact after you have
pressed the emergency button. Carefully
leave the vehicle and move to a safe loca-
tion. The Response Center will automatically
contact local emergency officials with the
vehicle’s approximate location if they re-
ceive an automatic SOS signal and cannot
make voice contact with the vehicle occu-
pants.
i
While the call is connected you can change
to the navigation menu by pressing NAVI button
on the COMAND System unit.

The resulting figure equals the avail-
able amount of cargo and luggage load
capacity. For example, if the “XXX”
amount equals 1400 lbs. and there will
be five 150 lbs. passengers in your
vehicle, the amount of available cargo
and luggage load capacity is 650 lbs.
(1400-750 (5 x150) = 650 lbs.)
Step 5
Determine the combined weight of
luggage and cargo being loaded on the
vehicle. That weight may not safely
exceed the available cargo and luggage
load capacity calculated in step 4.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 300).
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 297).
300 OperationTires and wheelsCertification label
Even after careful determination of the
combined weight of all occupants, cargo
and the trailer tongue load (if applicable)
(page 300) 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 434).Gross Vehicle Weight Rating (GVWR): The
total weight of the vehicle, all occupants,
all cargo, and the trailer tongue load
(
page 300) 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 be-
tween 10% and 15% of the trailer weight
and everything 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.

Where will I find...?
Store the collapsible tire by carrying
out the steps described in “Removing
the collapsible tire” (
page 392) in re-
verse order.
Compressing the collapsible tire
(CLS 63 AMG with Performance Pack-
age* only)
The 19" collapsible tire must be com-
pressed with two tensioning straps before
you can store it back in the trunk.
Extend the tensioning strap by pulling
the slider.
Place tensioning strap around spare
wheel rim and collapsible tire with the
buckle facing the inside of the rim.
Close the buckle.
Pull the loose end of the tensioning
strap.
The tensioning strap must be pulled as
tight as possible.
Vehicle tool kit
The vehicle tool kit is stored in the com-
partment underneath the trunk floor
(page 391).
The vehicle tool kit includes:
One pair of universal pliers
One towing eye bolt
One wheel wrench
One alignment bolt
One fuse extractor
One collapsible wheel chock
Spare fuses
i
Vehicles with 19" collapsible tire only: Be-
fore storing the collapsible tire in trunk fasten
tensioning straps, see “Compressing the col-
lapsible tire (CLS 63 AMG with Performance
Package* only)” (
page 393).
!
Always lower trunk floor before closing the
trunk.

The electrical air pump is located in the stor-
age well casing (

The tensioning straps are shown in red for
illustration purposes. The tensioning straps on
the spare wheel of your vehicle are black.
425 Practical hints
Towing the vehicle
Towing the vehicle
Mercedes-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 wheels raised only so
far as necessary to have the vehicle moved
to a safe location where the recommended
towing methods can be employed.!
Do not tow-start the vehicle.
!
Use flatbed or wheel lift/dolly equipment
with SmartKey in starter switch turned to
position0.
Do not tow with sling-type equipment. Towing
with sling-type equipment over bumpy roads will
damage radiator and supports.
To prevent damage during transport, do not tie
down vehicle by its chassis or suspension parts.
Switch off the automatic central (
page 165)
locking.
Warning!
G
If circumstances require towing the vehicle
with all wheels on the ground, always tow
with a tow bar if:
the engine will not run
there is a malfunction in the brake sys-
tem
there is a malfunction in the power sup-
ply or in the vehicle’s electrical system
as that will be necessary to adequately con-
trol the towed vehicle.
Prior to towing the vehicle with all wheels on
the ground, make certain that the SmartKey
is in starter switch position2.
If the SmartKey is left in the starter switch
position0 for an extended period of time, it
can no longer be turned in the switch. In this
case, the steering is locked. To unlock,
remove SmartKey from starter switch and
reinsert.
Warning!
G
With the engine not running, there is no
power assistance for the steering system. In
this case, it is important to keep in mind that
a considerably higher degree of effort is nec-
essary to steer the vehicle. Adapt your driv-
ing accordingly.!
If the vehicle is towed with the front axle
raised, the gear selector lever must be in
positionN and the engine must be shut off
(SmartKey in starter switch position0 or1).
Active braking action through the ESP
® may
otherwise seriously damage the brake system.
When towing the vehicle with all wheels on the
ground, the selector lever must be in positionN
and the SmartKey must be in starter switch
position2.
When towing the vehicle with all wheels on the
ground or the front axle raised, the vehicle may
be towed only for distances up to 30 miles
(50 km) and at a speed not to exceed 30 mph
(50 km/h).
