Characteristics when ESP®is deactivated
If ESP®is deactivated and one or more wheels
start to spin, the ÷ESP®warning lamp in the
instrument cluster flashes. In such situations,
ESP
®will not stabilize the vehicle.
If you deactivate ESP®:
RESP®no longer improves driving stability.
REngine torque is no longer limited and the
drive wheels are able to spin.
RTraction control is still activated.
RESP®still provides support when you brake
firmly.
RMercedes-AMG vehicles: and are driving a
speed at above 62 mph (100 km/h), ESP®still
intervenes when one wheel reaches its grip
limit even though it is deactivated.
RAll other models: and are driving at a speed
above 37 mph (60 km/h), ESP®still inter-
venes when one wheel reaches its grip limit
even though it is deactivated.
Mercedes-AMG vehicles: if ESP
®is deactiva-
ted, it is reactivated automatically if you are
driving at a speed above 62 mph (100 km/h) or
you exceed a certain lateral acceleration.
All other models: if ESP
®is deactivated, it is
re
activated automatically if you are driving at a
speed above 37 mph (60 km/h) or you exceed a
certain lateral acceleration.
Trailer stabilization
General information
If your vehicle/trailer combination begins to
swerve, ESP®assists you in this situation. ESP®
slows the vehicle down by braking and limiting
the engine output until the vehicle/trailer com-
bination has stabilized.
Important safety notes
GWARNING
If road and weather conditions are poor,
trailer stabilization will not be able to prevent
the vehicle/trailer combination from swerv-
ing. Trailers with a high center of gravity can
tip over before ESP
®can detect this. There is
a risk of an accident.
Always adapt your driving style to the prevail-
ing road and weather conditions.
If your vehicle with trailer (vehicle/trailer com-
bination) begins to lurch, you can only stabilize
the vehicle/trailer combination by depressing
the brake firmly.
ESP
®trailer stabilization is active above speeds
of approximately 37 mph (60 km/h).
ESP
®trailer stabilization does not work if ESP®
is deactivated or malfunctioning.
EBD (electronic brake force distribu-
tion)
General information
EBD monitors and controls the brake pressure
on the rear wheels to improve driving stability
while braking.
Important safety notes
iObserve the "Important safety notes" sec-
tion (Ypage 58).
GWARNING
If EBD is malfunctioning, the rear wheels can
lock, e.g. under full braking. This increases the
risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified spe-
cialist workshop.
Observe information regarding indicator and
warning lamps (
Ypage 194) as well as display
messages (Ypage 176).
ADAPTIVE BRAKE
ADAPTIVE BRAKE provides increased braking
safety. In addition to the braking function,
ADAPTIVE BRAKE also has the HOLD function
(
Ypage 142) and hill start assist (Ypage 107).

SmartKey
Important safety notes
GWARNING
If children are left unsupervised in the vehicle,
they could:
Ropen the doors, thus endangering other
people or road users.
Rget out and disrupt traffic.
Roperate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
Rrelease the parking brake.
Rshifting the automatic transmission out of
park position P
RStart the engine.
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 or animals unattended in the
vehicle. Always keep the SmartKey out of
reach of children.
GWARNING
If you attach heavy or large objects to the
SmartKey, the SmartKey could be uninten-
tionally turned in the ignition lock. This could
cause the engine to be switched off. There is a risk of an accident.
Do not attach any heavy or large objects to the
SmartKey. Remove any bulky key rings before
inserting the SmartKey into the ignition lock.
!Keep the SmartKey away from strong mag-
netic fields. Otherwise, the remote control
function could be affected.
Strong magnetic fields can occur in the vicin-
ity of powerful electrical installations.
Do not keep the SmartKey:
Rwith electronic devices, e.g. a mobile phone
or another SmartKey.
Rwith metallic objects, e.g. coins or metal foil.
Rinside metallic objects, e.g. a metal case.
This can affect the functionality of the Smart- Key. A check which periodically establishes a radio
connection between the vehicle and the Smart-
Key determines whether a valid SmartKey is in
the vehicle. This occurs, for example:
Rwhen starting the engine
Rwhile driving

tacts. There is a risk of fatal injury.
Never touch the parts or the electrical con-
tacts of the Xenon bulb. Always have work onthe Xenon bulbs carried out at a qualified spe-
cialist workshop.
GWARNING
Bulbs, lamps and connectors can get very hot
when operating. If you change a bulb, you
could burn yourself on these components.
There is a risk of injury.
Allow these components to cool down before
changing a bulb.
Do not use a bulb if it has been dropped or if its glass tube has been scratched.
The bulb may explode if:
Ryou touch it
Rit is hot
Ryou drop it
Ryou scratch it
Use bulbs only in closed lamps that have been
designed for this purpose. Only install spare
bulbs of the same type and the specified volt-
age.
Marks on the glass tube reduce the service life
of the bulbs. Do not touch the glass tube with
your bare hands. If necessary, clean the glass
tube when cold with alcohol or spirit and rub it
off with a lint-free cloth.
Protect bulbs from moisture during operation.
Do not allow bulbs to come into contact with

Notes on breaking-in a new vehicle
Important safety notes
The sensor system of some driving and driving
safety systems adjusts automatically while a
certain distance is being driven after the vehiclehas been delivered or after repairs. Full system
effectiveness is not reached until the end of this
teach-in procedure.
New and replaced brake pads and discs only
reach their optimum braking effect after several hundred kilometers of driving. Compensate for
this by applying greater force to the brake pedal.
The first 1000 miles (1500 km)
The more you look after the engine when it is
new, the more satisfied you will be with its per-
formance in the future.
RYou should therefore drive at varying vehicle
and engine speeds for the first 1,000 miles
(1,500 km).
RAvoid heavy loads, e.g. driving at full throttle,
during this period.
RWhen shifting gears manually, shift up in good
time, before the tachometer needle reaches
Ô of the way to the red area of the tachom-
eter display.
RDo not manually shift to a lower gear to brake
the vehicle.
RTry to avoid depressing the accelerator pedal
beyond the pressure point (kickdown).
Additional breaking-in notes for Mercedes-AMG
vehicles:
RDo not drive faster than 85 mph (140 km/h)
for the first 1,000 miles (1,500 km).
ROnly briefly allow the engine to reach a max-
imum engine speed of 4,500 rpm.
RAvoid driving off-road before the first differ-
ential oil change at 2,000 miles (3,000 km).
RIdeally, for the first 1,000 miles (1,500 km),
drive in program C.
After 1,000 mile s(1,500 km), you can increase
the engine speed gradually and bring the vehicle
to full speed.
You shoul
d also observe these notes on break-
ing in if the engine or parts of the drive train on
your vehicle have been replaced.
Always observe the maximum permissible
speed.
Axle differential transmission
(Mercedes-AMG vehicles)
Change the oil after a breaking-in period of
2,000 miles (3,000 km) to improve protection of
the axle differential transmission.
This oil change prolongs the service life of the
axle differential transmission. Have the oil
change carried out at a qualified specialist work- shop.
Axle differential transmission and
portal transmission (G 500 4x42)
Change the oil after a breaking-in period of
2,000 miles (3,000 km) to improve protection of
the axle differential transmission and portal
transmission.
This oil change prolongs the service life of the
axle differential and portal transmission. Have
the oil change carried out at a qualified special-ist workshop.
Driving
Important safety notes
GWARNING
Objects in the driver's footwell may restrict
the clearance around the pedals or block a
depressed pedal. This jeopardizes the oper-
ating and road safety of the vehicle. There is a risk of an accident.
Stow all objects securely in the vehicle so that
they do not get into the driver's footwell.
When using floormats or carpets, make sure
that they are properly secured so that they do not slip or obstruct the pedals. Do not place
several floormats or carpets on top of one
another.
GWARNING
Unsuitable footwear can hinder correct usage of the pedals, e.g.:
Rshoes with thick soles
Rshoes with high heels
Rslippers
104Driving
Driving and parking
Page 107 of 294

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:
Roverheat and cause a fire
Rlose 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 sta-
tionary.
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 other-
wise be significantly shortened. Do not use
the engine's full performance until it has
reached operating temperature.
!Mercedes-AMG vehicles: at low engine oil
temperatures below 68 ‡ (+20 †), the max-
imum engine speed is restricted in order to
protect the engine. To protect the engine and
maintain smooth engine operation, avoid driv-
ing at full throttle when the engine is cold.

Starting the engine
Important safety notes
GWARNING
If children are left unsupervised in the vehicle,
they could:
Ropen the doors, thus endangering other
people or road users.
Rget out and disrupt traffic.
Roperate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
Rrelease the parking brake.
Rshifting the automatic transmission out of
park position P
RStart the engine.
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 or animals unattended in the
vehicle. Always keep the SmartKey out of
reach of children.
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.
GWARNING
Flammable materials introduced through
environmental influence or by animals can
ignite if in contact with the exhaust system or
parts of the engine that heat up. There is a risk
of fire.
Carry out regular checks to make sure that
there are no flammable foreign materials in
the engine compartment or in the exhaust
system.
!Do not depress the accelerator when start-
ing the engine.
Starting procedure
XShift the automatic transmission to position
j.
XMake sure that the parking brake is applied.
XTurn the SmartKey to position 3in the igni-
tion lock (Ypage 105) and release it as soon

You can also use the touch-start function. To do
this, turn the SmartKey to position 3
(
Ypage 105) and release it immediately. The
engine then starts automatically.
Pulling away
General notes
GWARNING
If the engine speed is above the idling speed
and you engage transmission position Dor R,
the vehicle could pull away suddenly. There is
a risk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do not simultaneously accelerate.
!Do not depress the accelerator pedal while
depressing the brake pedal. This impairs
engine performance and results in premature
wear on the brake system and drivetrain.
!If a warning tone sounds and the ReleasePark. Brakemessage appears in the multi-
function display, the parking brake is still
applied. Release the parking brake.
Depress the accelerator carefully when pulling
away.
The vehicle locks centrally once you have pulled
away. The locking knobs in the doors drop down.
You can open the doors from the inside at any
time.
You can also deactivate the automatic locking
feature (
Ypage 170).
It is possible to shift the transmission from posi-
tion jto the desired position only if you
depress the brake pedal. Only then is the selec-
tor lever lock released.
