Transfer case
!
Performance tests may only be carried
out on a 2-axle dynamometer. The brake
system or transfer case could otherwise be
damaged. Contact a qualified specialist
workshop for a performance test.
!To prevent ESP®from intervening, the
ignition must be switched off (SmartKey or
the Start/Stop button in position 0or 1) if:
Rthe electric parking brake is being tested
on a brake dynamometer.
Rthe vehicle is being towed with only one
axle raised (not permitted for vehicles
with 4MATIC).
The brake system could otherwise be dam-
aged.
!Vehicles with 4MATIC must not be towed
with either the front or the rear axle raised,
as doing so will damage the transmission.
This section is only valid for vehicles with 4-
wheel drive (4MATIC). Power is always trans-
mitted to both axles.
Refueling
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
Fuel is poisonous and hazardous to health.
There is a risk of injury.
You must make sure that fuel does not come into contact with your skin, eyes or clothing
and that it is not swallowed. Do not inhale fuel
vapors. Keep fuel away from children.
Refueling167
Driving and parking
Z

If you or others come into contact with fuel,
observe the following:
RWash away fuel from skin immediately
using soap and water.
RIf fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance with-
out delay.
RIf fuel is swallowed, seek medical assis-
tance without delay. Do not induce vomit-
ing.
RImmediately change out of clothing which
has come into contact with fuel.
GWARNING
Electrostatic buildup can create sparks and
ignite fuel vapors. There is a risk of fire and
explosion.
Always touch the vehicle body before opening
the fuel filler flap or touching the fuel pump
nozzle. Any existing electrostatic buildup is
thereby discharged.
Do not get into the vehicle again during the
refueling process. Otherwise, electrostatic
charge could build up again.
!Do not use diesel to refuel vehicles with a
gasoline engine. Do not switch on the igni-
tion if you accidentally refuel with the
wrong fuel. Otherwise, the fuel will enter
the fuel system. Even small amounts of the wrong fuel could result in damage to the
fuel system and the engine. Notify a quali-
fied specialist workshop and have the fuel
tank and fuel lines drained completely.
!Overfilling the fuel tank could damage the
fuel system.
!Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
!Use a filter when refueling from a fuel can.
Otherwise, the fuel lines and/or injection
system could be blocked by particles from
the fuel can. If you overfill the fuel tank, fuel could spray
out when the fuel pump nozzle is removed.

Driving tips
General driving tips
Important safety notes
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 you operate mobile communication equip-
ment while driving, you will be distracted from traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate this equipment when the vehicle
is stationary.
Observe the legal requirements for the coun-
try in which you are driving. Some jurisdic-
tions prohibit the driver from using a mobile
phone while driving a vehicle.
If you make a call while driving, always use
hands-free mode. Only operate the telephone
when the traffic situation permits. If you are
unsure, pull over to a safe location and stop
before operating the telephone.
Bear in mind that at a speed of only 30 mph
(approximately 50 km/h), the vehicle covers
a distance of 44 ft (approximately 14 m) per
second.
Drive sensibly – save fuel
Observe the following tips to save fuel:
XThe tires should always be inflated to the
recommended tire pressure.
XRemove unnecessary loads.
XRemove roof racks when they are not nee-
ded.
XWarm up the engine at low engine speeds.
XAvoid frequent acceleration or braking.
XHave all maintenance work carried out as
indicated by the service intervals in the
Maintenance Booklet or by the service
interval display.
Fuel consumption also increases when driv-
ing in cold weather, in stop-start traffic and in
hilly terrain.
Drinking and driving
GWARNING
Drinking and driving and/or taking drugs and driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and judg-
ment.
The possibility of a serious or even fatal acci-
dent is greatly increased when you drink or
take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or tak-
ing drugs.
Emission control
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.
Certain engine systems are designed to keep
the level of poisonous components in exhaust
fumes within legal limits.
174Driving tips
Driving and parking

additional warning messages in the multi-
function display.
The brake fluid level may be too low due to
brake pad wear or leaking brake lines.
Have the brake system checked immedi-
ately. This work should be carried out at a
qualified specialist workshop.
!Vehicles with 4MATIC:function or per-
formance tests may only be carried out on
a 2-axle dynamometer. If you wish to oper-
ate the vehicle on such a dynamometer,
please consult an authorized Mercedes-
Benz Center in advance. You could other-
wise damage the drive train or the brake
system.
!Vehicles with 4MATIC: the ESP®system
operates automatically. The engine and the
ignition must therefore be switched off (the
SmartKey must be in position 0or 1in the
ignition lock or the Start/Stop button must
be in position 0or 1) if the electric parking
brake is tested on a brake dynamometer.
Braking triggered automatically by ESP
®
may cause severe damage to the brake
system.
!Vehicles without 4MATIC: the ESP®
system operates automatically. The engine
and the ignition must therefore be switched
off (the SmartKey must be in position 0or 1
in the ignition lock or the Start/Stop button
must be in position 0or 1) if:
Rthe electric parking brake is tested using
a brake dyn
amometer.
Rthe vehicle is towed with one axle raised.
Braking triggered automatically by ESP
®
may cause severe damage to the brake
system.
All checks and maintenance work on the
brake system must be carried out at a quali-
fied specialist workshop. Consult a qualified
specialist workshop to arrange this.
Have brake pads installed and brake fluid
replaced at a qualified specialist workshop. If the brake system has only been subject to
moderate loads, you should test the function-
ality of your brakes at regular intervals.
Information on BAS (Brake Assist) (
Ypage 68)
and BAS PLUS (Brake Assist PLUS)
(
Ypage 69).
For safety reasons, Mercedes-Benz recom-
mends only installing the following brake
disks and brake pads/linings:
Rbrake disks that have been approved by
Mercedes-Benz
Rbrake pads/linings that have been
approved by Mercedes-Benz or that are of
an equivalent standard of quality
Other brake disks or brake pads/linings can
compromise the safety of your vehicle.
Always replace all brake disks and brake
pads/linings on an axle at the same time.
Always install new brake pads/linings when
replacing brake disks.
The vehicle is equipped with lightweight
brake disks to which the wheel assembly with rim and threaded connection is matched.
The use of brake disks other than th ose
appr

oved by Mercedes-Benz can change the
track width and is subject to approval, if appli-
cable.
Shock-type loads when handling the brake
disks, such as when changing wheels, can
lead to a reduction in comfort when driving
with lightweight brake disks. Avoid shock-
type loads on the lightweight brake disks,
particularly on the brake plate.
Mercedes-Benz recommends that you only
use brake fluid that has been specially
approved for your vehicle by Mercedes-Benz,
or which corresponds to an equivalent quality
standard. Brake fluid which has not been
approved for Mercedes-Benz vehicles or
which is not of an equivalent quality could
affect your vehicle's operating safety.

MAGIC BODY CONTROL
General notes
MAGIC BODY CONTROL consists of Active
Body Control (ABC), ROAD SURFACE SCAN,
the CURVE cornering function as well as auto-
matic vehicle stabilization in the event of a
crosswind.
Your vehicle automatically adjusts its ride
height to reduce fuel consumption. The sus-
pension mode is adjusted according to your
selection (SPORT, COMFORT or CURVE), the
road surface conditions and the vehicle load.
A multifunction camera detects bumps in the
road surface before the vehicle drives over
them. This reduces chassis movements.
Important safety notes
GWARNING
When the vehicle is being lowered, people
could become trapped if their limbs are
between the vehicle body and the wheels or
underneath the vehicle. There is a risk of
injury.
Make sure no one is underneath the vehicle or
in the immediate vicinity of the wheel arches
when the vehicle is being lowered.
!The vehicle is lowered when the engine is
switched off. When parking, position your
vehicle so that it does not make contact
with the curb as the vehicle is lowered. Your
vehicle could otherwise be damaged.
Crosswind Assist
The crosswind stabilization operates by
changing wheel loads through distortion of
the ABC spring struts. It reduces impairments
in handling when driving in a straight line and
assists during countersteering. Crosswind Assist is active in the speed range
between 50 mph (80 km/h) and
130 mph (210 km/h) when driving straight
ahead or cornering gently.
Active Body Control ABC
Vehicle level
All vehicles except AMG vehicles:
depend-
ing on the vehicle level that has been set, the
vehicle automatically adjusts its height
dependent on the current speed. The vehicle
is lowered by up to 0.6 in (15 mm) as the
speed increases. As the speed is reduced, the
vehicle is raised up to the set vehicle height.
In the event of poor road surface conditions,
the vehicle automatically raises by up to 0.4 in
(10 mm) and harder damping is selected.
AMG vehicles: depending on the vehicle
level that has been selected, the vehicle auto-
matically adjusts its height dependent on the current speed. The vehicle is lowered by up to
0.4 in (10 mm) below the normal level as thespeed increases. As the speed is reduced, the
vehicle is raised up to the set vehicle height.
Select the "Normal" setting for normal road
conditions and "Raised" for driving with snow
chains or in particularly poor road conditions.
Your selection remains stored even if you
remove the SmartKey from the ignition lock.
The "Raised level" setting is canceled if you:
Rare driving faster than approximately
75 mph (120 km/h).
Rdrive for approximately three minutes at a
speed over 50 mph (80 km/h).

Suspension tuning
The electro-hydraulically controlled ABC sus-
pension system works continuously. This
improves driving safety and comfort. The sys-
tem detects the vehicle level and the vehicle
load and adjusts the setting accordingly. You
can also choose between a particularly sporty
mode (SPORT), a comfortable mode (COM-
FORT), as well as a comfortable mode with
cornering function (CURVE).
The ABC suspension system is tuned individ-
ually to each wheel and depends on:
Ryour driving style, e.g. sporty
Rthe road surface condition, e.g. bumps
Ryour individual selection, i.e. sporty or com-
fort or comfort with the CURVE dynamic
cornering function
Rthe vehicle load
Rthe force of the side wind
Your selection remains stored even if you
remove the SmartKey from the ignition lock.
The firmer suspension setting in SPORT mode
ensures even better contact with the road.
The steering response behavior is sporty.
Select this mode on winding country roads or
highways, for example.
