the driver's footwell. Install the floormats
securely and as specified in order to ensure
sufficient clearance for the pedals. Do not useloose floormats and do not place floormats ontop of one another.
GWARNING
Unsuitable footwear can hinder correct usage of the pedals, e.g.:
R shoes with thick soles
R shoes with high heels
R slippers
There is a risk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals.
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
GWARNING
If the parking brake has not been fully
released when driving, the parking brake can:
R overheat and cause a fire
R lose its hold function.
There is a risk of fire and an accident. Release
the parking brake fully before driving off.
!Warm up the engine quickly. Do not use
the engine's full performance until it has
reached operating temperature.
Only shift the automatic transmission to
the desired drive position when the vehicle
is stationary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery
roads. You could otherwise damage the
drive train.
!Avoid high engine speeds when the
engine is cold. The engine's service life
could otherwise be significantly shortened.
Do not use the engine's full performance
until it has reached operating temperature.
!AMG vehicles: at low engine oil temper-
atures below 68 ‡ (+20 †), the maximum
engine speed is restricted in order to pro-
tect the engine. To protect the engine and
maintain smooth engine operation, avoid
driving at full throttle when the engine is
cold.
SmartKey positions
gTo remove the SmartKey
1Power supply for some consumers, such
as the windshield wipers
2Ignition (power supply for all consumers)
and drive position
3To start the engine
As soon as the ignition is switched on, all the
indicator lamps in the instrument cluster light up. If an indicator lamp does not go out after
starting the engine or lights up while driving,
see ( Ypage 162).
If the SmartKey is in position 0in the ignition
lock for an extended period of time, it can no
longer be turned in the ignition lock. The
steering is then locked. To unlock, remove the SmartKey and reinsert it into the ignition lock.
The steering is locked when you remove the
SmartKey from the ignition lock.

Manual drive program
General information
The manual drive program is only available on AMG vehicles . In manual drive program M,
you can permanently change gear yourself by
using the steering wheel paddle shifters. The
transmission must be in position D. The gear
currently selected and engaged is shown in
the multifunction display.
Manual drive program Mdiffers from drive
programs Eand Swith regard to spontaneity,
responsiveness and smoothness of gear
changes.
Switching on the manual drive program
X Shift the transmission to position D.
X Press the program selector button repeat-
edly until Mappears in the multifunction
display, see Digital Operator's Manual.
Upshifting
!In manual drive program M, the automatic
transmission does not shift up automati-
cally even when the engine limiting speed
for the current gear is reached. When the engine limiting speed is reached, the fuel
supply is cut to prevent the engine from
overrevving. Always make sure that the
engine speed does not reach the red area of
the tachometer. There is otherwise a risk of
engine damage.
X If relevant gearshift recommendation :
appears in the multifunction display on the instrument cluster, pull on the right-hand
steering wheel paddle shifter (see the Dig-
ital Operator's Manual).
The automatic transmission shifts to rec-
ommended gear ;.

Important safety notes
GWARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is a risk of fire and explo-
sion.
You must avoid fire, open flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating before
refueling.

GWARNING
The automatic transmission switches to neu-
tral position Nwhen you switch off the engine.
The vehicle may roll away. There is a risk of an
accident.
After switching off the engine, always switch
to parking position P. Prevent the parked vehi-
cle from rolling away by applying the parkingbrake.
Information in the Digital Operator'sManual
A description of how to switch off the engine
can be found in the Digital Operator's Manual.
Parking brake
GWARNING
If you must brake the vehicle with the parking brake, the braking distance is considerably
longer and the wheels could lock. There is anincreased danger of skidding and accidents.
Only use the parking brake to brake the vehi-cle when the service brake is faulty. Do not
apply the parking brake too firmly. If the
wheels lock, release the parking brake until
the wheels begin turning again.
GWARNING
If you leave children unsupervised in the vehi- cle, they could set it in motion by, for example:
R release the parking brake.
R shift the automatic transmission out of the
parking position P.
R start the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
iWhen you apply parking brake ;to brake
the vehicle, the brake lamps do not light up.
X To apply: pull parking brake ;up firmly.
Parking brake ;is applied.
When the ignition is switched on or the
engine is running, the F(USA only) or
J (Canada only) indicator lamp is lit in
the instrument cluster.

stopping and backing up in a traffic-free location.
R Before driving, check:
- Trailer tow hitch
- Safety switch for braked trailers
- Safety chains
- Electrical connections
- Lights
- Wheels
R Adjust the exterior mirrors to provide an
unobstructed view of the rear section of the
trailer.
R If the trailer features electronically control-
led brakes, pull away the vehicle/trailer
combination carefully, manually brake
using the brake controller, and check the
brakes for correct function.
R Secure any objects on the trailer to prevent
the cargo from slipping when the vehicle is
in motion.
R If you couple up a trailer, regularly check
the cargo for secure fastening and make
sure that the trailer lamps and (if applica-
ble) the trailer brakes are functioning cor-rectly.
R Bear in mind that the handling will be less
stable when towing a trailer than when driv-
ing without one. Avoid sudden steeringmovements.
R The vehicle/trailer combination is heavier,
accelerates more slowly, has a decreased
gradient climbing capability and a longer
braking distance.
It is more susceptible to side winds and
requires more careful steering.
R If possible, avoid abrupt braking. Depress
the brake pedal moderately at first, so that
the trailer can activate its own brakes. Thenincrease the pressure on the brake pedal.
R If the automatic transmission continues to
shift back and forth between two gears
when driving up or downhill, restrict the
shift range. Select shift range 4, 3, 2,or1.
A lower gear and lower speed reduce the
risk of engine failure. R
When driving downhill, shift to a lower gear
to utilize the engine's braking effect.
Avoid continuous brake application as this
may overheat the vehicle brakes and, if
installed, the trailer brakes.
R If the coolant temperature increases dra-
matically while the air-conditioning system
is switched on, switch off the air-condition-
ing system.
Coolant heat can additionally be dissipated
by opening the windows and by setting the
blower fan and the interior temperature tomaximum.
R When overtaking, pay particular attention
to the extended length of your vehicle/
trailer combination.
Due to the length of your vehicle/trailer
combination, you will have to travel an addi-
tional distance beyond the vehicle you are
overtaking before returning to the previous lane.
Decoupling a trailer
!
Do not disconnect a trailer with an
engaged overrun brake. Otherwise, your
vehicle could be damaged by the rebound- ing of the overrun brake.
X Make sure that the automatic transmission
is set to position P.
X Apply the parking brake.
X Start the engine.
X Close all doors, including the rear door.
X Apply the trailer's parking brake.
X Detach the trailer cable and decouple thetrailer.
X Switch off the engine.
