When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
The seats can still be adjusted when there is no
SmartKey in the ignition lock.
GWARNING
When you adjust a seat, you or other vehicle
occupants could become trapped, e.g. on the seat guide rail. There is a risk of injury.
Make sure when adjusting a seat that no one
has any body parts in the sweep of the seat.
Observe the safety notes on "Air bags"
(
Ypage 40) and "Children in the vehicle"
(Ypage 46).
GWARNING
You could lose control of your vehicle if you do the following while driving:
Radjust the driver's seat, head restraint,
steering wheel or mirrors
Rfasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt before starting the engine.
GWARNING
If the head restraints are not installed or not
adjusted correctly, they cannot provide pro-
tection as intended. There is an increased risk
of injury in the head and neck area, e.g. in the event of an accident or when braking.
Always drive with the head restraints instal-
led. Before driving off, make sure for every
vehicle occupant that the center of the head
restraint supports the back of the head at
about eye level.
Make sure that you do not rotate the head
restraints of the front and rear seats when
adjusting the head restraints. Otherwise, you
cannot adjust the height and angle of the head
restraints correctly.
Adjust the head restraint so that it is as close as
possible to your head.
GWARNING
According to accident statistics, children are
safer when properly restrained on the rear
seats than on the front-passenger seat. Thus,
we strongly recommend that children be
placed in the rear seat whenever possible.
Regardless of seating position, children 12
years old and under must be seated and prop-
erly secured in an appropriately sized child
restraint system or booster seat recommen-
ded for the size and weight of the child. For
additional information, see the "Children in
the vehicle" section.
A child's risk of serious or fatal injuries is sig-
nificantly increased if the child restraints are
not properly secured in the vehicle and/or the
child is not properly secured in the child
restraint.
!To avoid damage to the seats and the seat
heating, observe the following information:
Rkeep liquids from spilling on the seats. If
liquid is spilled on the seats, dry them as
soon as possible.
Rif the seat covers are damp or wet, do not
switch on the seat heating. The seat heat-
ing should also not be used to dry the seats.
Rclean the seat covers as recommended;
see the "Interior care" section.
Rdo not transport heavy loads on the seats.
Do not place sharp objects on the seat
cushions, e.g. knives, nails or tools. The
seats should only be occupied by passen-
gers, if possible.
Rwhen the seat heating is in operation, do
not cover the seats with insulating materi-
als, e.g. blankets, coats, bags, seat covers,
child seats or booster seats.
!Make sure that there are no objects in the
footwell under or behind the seats when mov-
ing the seats back. There is a risk that the
seats and/or the objects could be damaged.
!When the rear bench seat is folded for-
wards, the front seats cannot be moved to
their rearmost position. You could otherwise
damage the seats and the rear bench seat.
!Make sure that the sun visor is folded up
before adjusting the backrest and head
restraint height. The head restraint and sun

HOLD function
General notes
The HOLD function can assist the driver in the
following situations:
Rwhen pulling away, especially on steep slopes
Rwhen maneuvering on steep slopes
Rwhen 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 driving
off-road, on steep uphill or downhill gradients
or on slippery or loose surfaces. The HOLD
function cannot hold the vehicle on such sur-
faces.
Activation conditions
You can activate the HOLD function if:
Rthe vehicle is stationary
Rthe engine is running or if it has been auto-
matically switched off by the ECO start/stop
function
Rthe engine is running
Rthe driver's door is closed or your seat belt is
fastened
Rthe transmission is in position D,R or N
RDISTRONIC 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.
XMake sure that the activation conditions are
met.
XDepress the brake pedal.
XQuickly depress the brake pedal further until
ë appears in the multifunction display.
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 away despite being braked by the HOLD function if:
Rthere is a malfunction in the system or in
the voltage supply.
Rthe HOLD function has been deactivated by
pressing the accelerator pedal or the brake
pedal, e.g. by a vehicle occupant.
Rthe electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
Rthe 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 automatically if:
Ryou accelerate and the transmission is in
position Dor R.
Ryou shift the transmission to position P.
Ryou depress the brake pedal again with a cer-
tain amount of pressure untilëdisap-
pears from the multifunction display.
Ryou 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 vehi-
cle with all wheels in full contact with the
ground.
!When testing the parking brake, operate the
vehicle only briefly (for a maximum of ten sec-
onds) on a brake test dynamometer. When
doing this, turn the SmartKey to position 0or
1 in the ignition. Failure to do this can cause
damage to the drive train or the brake system.
