the Xenon bulb and touch the electrical con-
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
liquids.

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

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
as the engine is running.
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.
iUpshifts take place at higher engine speeds
after a cold start. This helps the catalytic con-

verter to reach its operating temperature
more quickly.
Pulling away with a trailer
To ensure that you do not roll back when pulling
away on an uphill slope, apply the parking brake.
XDepress the brake pedal and keep it
depressed.
XShift the automatic transmission to position
hork.
iAlways wait until the shifting process is
complete before driving off.
XRelease the parking brake (Ypage 123).
XRelease the brake pedal.
XCarefully depress the accelerator pedal.
Hill start assist
Hill start assist helps you when pulling away
forward or in reverse on an uphill gradient. It
holds the vehicle for a short time after you have
removed your foot from the brake pedal. This
gives you enough time to move your foot from
the brake pedal to the accelerator pedal and to
depress it before the vehicle begins to roll.
GWARNING
After a short time, hill start assist will no lon-
ger brake your vehicle and it could roll away.
There is a risk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist will not function if:
Ryou are pulling away on a level road or on a
downhill gradient
Rthe transmission is in position i
Rthe parking brake is applied
RESP®is malfunctioning
ECO start/stop function
Important safety notes
GWARNING
If the engine is switched off automatically and
you exit the vehicle, the engine is restarted
automatically. The vehicle may begin moving.
There is a risk of accident and injury.
If you wish to exit the vehicle, always turn off
the ignition and secure the vehicle against
rolling away.
General notes
The ECO start/stop function switches the
engine off automatically when the vehicle stops
moving.
The engine starts automatically when the driver
wants to pull away again. The ECO start/stop
function thereby helps you to reduce the fuel
consumption and emissions of your vehicle.
The ECO start/stop function is activated each
time the engine is switched on or when you
switch the drive program (except Mercedes-
AMG vehicles).
Mercedes-AMG vehicles: the ECO start/stop
function is activated after the engine is restarted
and is only available in drive program C. When
drive program Sor Mis selected, the ECO start/
stop function is deactivated.
The system is operational if all conditions for
automatic engine switch-off have been fulfilled
(
Ypage 108) and the èsymbol is shown in
green in the multifunction display.
If not all conditions for automatic engine switch-
off are fulfilled (
Ypage 108), the èECO
symbol is shown in yellow in the multifunction
display.
If the ECO start/stop function has been man-
ually deactivated (
Ypage 108) or a malfunction
has caused the system to be deactivated, the
è ECO symbol is not displayed.
