90 Safety and SecurityDriving safety systems
The electro-hydraulic brake system is auto-
matically activated when you

unlock the vehicle with the SmartKey
or the KEYLESS-GO*


open the driver’s or passenger door


turn the SmartKey in the starter switch
to position1


in vehicles with KEYLESS-GO*, press
the start/stop button on the gear
selector lever once


depress the brake pedal


release the parking brake
Warning!
G
The electro-hydraulic brake system requires
electrical power to operate.
A malfunction in the vehicle’s power supply
or electrical system may impair brake sys-
tem operation and switch it into its emer-
gency operation mode. In such a case, the
red brake warning lamp (
page 354) and
warning messages in the instrument cluster
(
page 363) come on while driving. To
brake, the driver must then apply signifi-
cantly greater brake pedal pressure and
depress the pedal much further to obtain
the expected braking effect. If necessary,
apply full pressure to the brake pedal.
Brakes may only be applied to the front
wheels. Stopping distance is increased!
If there is a malfunction in the
electro-hydraulic brake system, we recom-
mend that the vehicle be transported with
all wheels off the ground using flatbed or ap-
propriate wheel lift/dolly equipment.
A tow bar must be used if circumstances do
not permit the use of the recommended
towing methods and the vehicle requires
towing with all four wheels on the ground.
Towing the vehicle with all four wheels on
the ground is only permissible for distances
up to 30 miles (50 km) and at a speed not to
exceed 30 mph (50 km/h). For more infor-
mation, refer to “Towing the vehicle”
(page 437).

96 Safety and SecurityAnti-theft systemsArming the tow-away alarm

KEYLESS-GO*.
The tow-away alarm is automatically
armed after about 30 seconds.
Disarming the tow-away alarm
To prevent triggering the tow-away alarm
feature, switch off the tow-away alarm
before towing the vehicle, or when parking
on a surface subject to movement, such as
a ferry or auto train.The button is located on the overhead con-
trol panel.

KEYLESS-GO*) an lock button at each
outside door handle.
iYou cannot disarm the tow-away alarm
when the ignition is switched on.
iWhen you unlock the vehicle, the
tow-away protection disarms automati-
cally.
The tow-away alarm remains disarmed
until you lock the vehicle again.

122 Controls in detailLocking and unlockingAutomatic central locking
The doors and the trunk automatically lock
when the ignition is switched on and the
wheels are turning at vehicle speeds of
approximately 9 mph (15 km/h) or more.
You can open a locked door from the in-
side. Open door only when conditions are
safe to do so.For more information on towing the vehi-
cle, see the “Practical hints” section
(
page 437).
You can deactivate the automatic locking
mode using the control system
(page 168).
Locking and unlocking from the inside
You can lock or unlock the doors and the
trunk from inside using the central locking
switch. This can be useful, for example, if
you want to lock the vehicle before starting
to drive.
The fuel filler flap cannot be locked or
unlocked with the central locking switch.
iThe doors unlock automatically after an
accident if the force of the impact ex-
ceeds a preset threshold.
The vehicle automatically locks when
the ignition is switched on and the
wheels are turning at vehicle speeds of
approximately 9 mph (15 km/h) or
more. You could therefore lock yourself
out when the vehicle

is pushed or towed


is on a test stand
Warning!
G
When leaving the vehicle, always remove the
SmartKey or the SmartKey with
KEYLESS-GO* from the starter switch, take
it with you, and lock the vehicle. Do not
leave children unattended in the vehicle, or
with access to an unlocked vehicle. Unsu-
pervised use of vehicle equipment may
cause an accident and/or serious personal
injury.

266 Controls in detailUseful featuresThe 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.
iThe 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 263) 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 COMAND System.

mation, refer to “Towing the vehicle”
(page 437). For more information, see
“Electro-hydraulic brake system”
(page 89).
With the engine not running, there is no
power assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the
vehicle.
Warning!
G
After driving in heavy rain for some time
without applying the brakes or through wa-
ter deep enough to wet brake components,
the first braking action may be somewhat
reduced and increased pedal pressure may
be necessary to obtain expected braking ef-
fect. Maintain a safe distance from vehicles
in front.
Resting your foot on the brake pedal will
cause excessive and premature wear of the
brake pads.
It can also result in the brakes overheating,
thereby significantly reducing their effec-
tiveness. It may not be possible to stop the
vehicle in sufficient time to avoid an acci-
dent.

308 OperationTires and wheelsStep 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 310).
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 305).


310 OperationTires and wheelsCertification label
Even after careful determination of the
combined weight of all occupants, cargo
and the trailer tongue load (if applicable)
(page 310) 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 446).Gross Vehicle Weight Rating (GVWR): The
total weight of the vehicle, all occupants,
all cargo, and the trailer tongue load
(
page 310) 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.
