HOLD function
General notes
The HOLD function can assist the driver in the
following situations: R when pulling away, especially on steep
slopes
R when maneuvering on steep slopes
R when waiting in traffic
The vehicle is kept stationary without the
driver having to depress the brake pedal.
The braking effect is canceled and the HOLD
function deactivated when you depress the
accelerator pedal to pull away.
iDo not use the HOLD function when driv-
ing off-road, on steep uphill or downhill gra- dients or on slippery or loose surfaces. The
HOLD function cannot hold the vehicle on
such surfaces.
Activation conditions
You can activate the HOLD function if: R the vehicle is stationary.
R the engine is running or it has been
switched off by the ECO start/stop func-
tion (AMG vehicles).
R the engine is running.
R the driver's door is closed or your seat belt
is fastened.
R the transmission is in position D,R or N.
R DISTRONIC PLUS is deactivated.
Activating the HOLD function
The vehicle's brakes are applied when the
HOLD function is activated. For this reason,
deactivate the HOLD function while in the car
wash or while towing.
X Make sure that the activation conditions
are met.
X Depress the brake pedal.
X Quickly depress the brake pedal furtheruntil ë appears in the multifunction dis-
play.
The HOLD function is activated. You can
release the brake pedal.
iIf depressing the brake pedal the first
time does not activate the HOLD function,
wait briefly and then try again.

Deactivating the HOLD function
GWARNING
When leaving the vehicle, it can still roll awaydespite being braked by the HOLD function if:
R there is a malfunction in the system or in
the voltage supply.
R the HOLD function has been deactivated by
pressing the accelerator pedal or the brake
pedal, e.g. by a vehicle occupant.
R the electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
R the battery is disconnected
There is a risk of an accident.
If you wish to exit the vehicle, always turn off the HOLD function and secure the vehicle
against rolling away.
The HOLD function is deactivated automati-
cally if: R you accelerate and the transmission is in
position Dor R.
R you shift the transmission to position P.
R you depress the brake pedal again with a
certain amount of pressure until ëdis-
appears from the multifunction display.
R you activate DISTRONIC PLUS.
On steep uphill or downhill gradients or if
there is a malfunction, the transmission may
also be automatically shifted into position P.
Permanent all-wheel drive
!
Never tow the vehicle with one axle
raised. This may damage the transfer case. Damage of this sort is not covered by the
Mercedes-Benz Limited Warranty. All
wheels must remain either on the ground or
be fully raised. Observe the instructions for
towing the vehicle with all wheels in full
contact with the ground.
!When testing the parking brake, operate
the vehicle only briefly (for a maximum of ten seconds) on a brake test dynamometer.
When doing this, turn the SmartKey to posi-
tion 0or 1in the ignition. Failure to do this
can cause damage to the drive train or the brake system.
!A function or performance test should
only be carried out on a two-axle dyna-
mometer. Before you operate the vehicle
on such a dynamometer, please consult a
qualified workshop. You could otherwise
damage the drive train or the brake system.
The all-wheel drive system ensures that all
four wheels are permanently driven. The all-
wheel drive system improves vehicle traction together with ESP ®
and 4ETS if a drive wheel
spins due to insufficient grip.
If a drive wheel spins due to insufficient grip: R Only depress the accelerator pedal as far as
necessary when pulling away.
R Take your foot off the accelerator, slowly,
while the vehicle is in motion.
The permanent all-wheel drive system can
neither reduce the risk of accident nor over-
ride the laws of physics if you fail to adapt
your driving style or if you are inattentive. The
all-wheel drive system cannot take into
account road, weather or traffic conditions.
The all-wheel drive system is only an aid. You
are responsible for maintaining a safe dis-
tance to the vehicle in front, for vehicle speed, for braking in good time and for staying in
lane.
In wintry driving conditions, always use winter
tires (M+S tires) and if necessary, snow
chains ( Ypage 232). Only in this way can the
maximum effect of all-wheel drive be ach-
ieved.
For information on driving off-road, see the
Digital Operator's Manual.

PARKTRONIC
Important safety notes
!When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer drawbars.
PARKTRONIC does not detect such objects
when they are in the immediate vicinity of
the vehicle. You could damage the vehicle
or the objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic
car wash, the compressed-air brakes on a
truck or a pneumatic drill could cause
PARKTRONIC to malfunction.
PARKTRONIC may not function correctly on uneven terrain.
PARKTRONIC is an electronic parking aid with ultrasonic sensors. It indicates visually and
audibly the distance between your vehicle
and an object.
PARKTRONIC is only an aid. It is not a replace-
ment for your attention to your immediate
surroundings. You are always responsible for
safe maneuvering, parking and exiting a park-
ing space. Ensure that the areas in front,
behind and to the side of the vehicle are safe
before maneuvering, parking or pulling away. There must not be any persons, animals or
objects in the area in which you are maneu-vering.
PARKTRONIC does not take into account any persons or objects located below or above
the detection range. As a result,
PARKTRONIC cannot warn you about objects
in this area.
PARKTRONIC is activated automatically when
you:
R switch on the ignition
R shift the transmission to position D,R or N
R release the parking brake
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h). It is reactivated at lowerspeeds. PARKTRONIC monitors the area around your
vehicle using six sensors in the front bumper
and four sensors in the rear bumper.Range of the sensors
General notes
:Example: sensors in the front bumper,
right-hand side
Side view
Top view
The sensors must be free from dirt, ice or
slush. Otherwise, they may not function cor-
rectly. Clean the sensors regularly, taking
care not to scratch or damage them( Y page 211).

Differential locks
General notes
GWARNING
When the differential locks are engaged, ABS, 4ETS, ESP ®
and BAS are deactivated. As a
result, the wheels could lock when braking
and the braking distance is increased. There is
a risk of an accident.
Disengage the differential locks immediately
on firm surfaces with good grip.
!In order to avoid damage to the transfer
case, you must operate the vehicle on a
dynamometer (1-axle dynamometer) onlyif:
R the axle not driven on is jacked up or
R the corresponding propeller shaft is dis-
connected and the transfer case differ-
ential lock is engaged.
Otherwise, the transfer case can be dam-aged.
Differential locks improve the traction of the vehicle.
Your vehicle is equipped with a differential
lock each for: R the transfer case: this controls the balance
between the front and rear axles.
R the rear axle: this controls the balance
between the wheels on the rear axle.
R the front axle: this controls the balance
between the wheels on the front axle.
Information on differential gear system
and differential lock
When the vehicle drives around a curve, the
wheels on the outside of the curve must cover
a greater distance. Therefore, the wheels turn more rapidly than on the inside. The differen-
tial, a gear system in the drive train, allows for
differing rotational speeds and facilitates cor- nering.

Coupling up a trailer
GWARNING
If you uncouple a trailer with the overrun
brake engaged, you could trap your hand
between the vehicle and the trailer drawbar.
There is a risk of injury.
Do not uncouple a trailer if the overrun brake
is engaged.
!Do not connect the trailer's brake system
(if featured) to the hydraulic brake system
of the towing vehicle, as the latter is equip-
ped with an anti-lock brake system. Doing
so will result in a loss of function of the
brake systems of both the vehicle and the
trailer.
Observe the maximum permissible trailer
dimensions (width and length). Most U.S. states and all Canadian provinces
require by law:
R safety chains between the towing vehicle
and the trailer. The chains should be cross-
wound under the trailer drawbar. They must
be fastened to the vehicle's trailer cou-
pling, not to the bumper or the axle.
Allow for enough play in the chains to facil- itate turning tight corners.
R a separate brake system for certain types
of trailer.
R a safety switch for braked trailers. Check
the specific legal requirements applicable
to your state.
If the trailer detaches from the towing vehi-
cle, the safety switch applies the trailer's
brakes.
X Make sure that the automatic transmission
is set to position P.
X Apply the vehicle's parking brake.
X Couple up the trailer.
X Establish all electrical connections.
Towing a trailer
There are numerous legal requirements con-
cerning the towing of a trailer, e.g. speed
restrictions. Make sure that your vehicle/
trailer combination complies with the local
requirements not only in your area of resi-
dence but also at any location to which you
are traveling. The police and local authorities
can provide reliable information.
Please observe the following when towing a
trailer:
R To acquaint yourself with driving with a
trailer and with the resulting changes to
handling, you should practice cornering,
