Transfer case
This section is only valid for vehicles with 4-
wheel drive (4MATIC). Power is always trans-
mitted to both axles.
!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.
!Vehicles with 4MATIC must not be towed
with either the front or the rear axle raised, as
doing so will damage the transmission.
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.
138Refueling
Driving and parking
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.
These systems only work at peak efficiency if
they are serviced exactly in accordance with the
manufacturer's specifications. Always have
work on the engine carried out at a qualified
specialist workshop. Mercedes-Benz recom-
mends that you use an authorized Mercedes-
Benz Center for this purpose. In particular, work
relevant to safety or on safety-related systems
must be carried out at a qualified specialist
workshop.
The engine settings must not be changed under any circumstances. Furthermore, all specific
service work must be carried out at regular
intervals and in accordance with the Mercedes-
Benz service requirements. Details can be found in the Maintenance Booklet.
ECO display
The ECO display provides feedback on how eco-
nomical your driving characteristics are. The
ECO display assists you in achieving the most
economical driving style for the selected set-
tings and prevailing conditions. Your driving
style can significantly influence the vehicle's
consumption.
The ECO display consists of three bars:
RAcceleration
RConstant
RCoasting
The percent value is the average value of the
three bars. The three bars and the mean value
begin at the value of 50%. A higher percentage
indicates a more economical driving style.
The ECO display does not indicate the actual fuel
consumption. A fixed percentage count in the
ECO display does not indicate a fixed consump-
tion.
Apart from driving style, consumption is
dependent on many factors such as, e.g.:
Rload
Rtire pressure
Rcold start
Rchoice of route
Relectrical consumers switched on
These factors are not included in the ECO dis-
play.
The evaluation of your driving style is carried out
using the following three categories:
RAcceleration(evaluation of all acceleration
processes):
-The bar fills up: moderate acceleration,
especially at higher speeds
-The bar empties: sporty acceleration
RConstant(assessment of driving behavior at
all times):
-The bar fills up: constant speed and avoid-
ance of unnecessary acceleration and
deceleration
-The bar empties: fluctuations in speed
RCoasting(assessment of all deceleration
processes):
-The bar fills up: anticipatory driving, keep-
ing your distance and early release of the
accelerator. The vehicle can coast without
use of the brakes.
-The bar empties: frequent braking
iAn economical driving style specially
requires driving at moderate engine speeds.
To achieve a higher value in the categories

and Constant:
Robserve the gearshift recommendations.
Rdrive in drive program E.
iOn long journeys at a constant speed, e.g.

Driving and parking
Have the brake system checked immediately.
Consult a qualified specialist workshop to
arrange this.
!Vehicles with 4MATIC: function or per-
formance tests may only be carried out on a 2-
axle dynamometer. If you wish to operate the
vehicle on such a dynamometer, please con-
sult a qualified specialist workshop in
advance. You could otherwise damage the
drive train or the brake system.
!Vehicles with 4MATIC: as the ESP®sys-
tem operates automatically, the engine and
the ignition must be switched off (SmartKey in
position 0or 1in the ignition lock or Start/
Stop button in position 0or 1) while the park-
ing brake is being tested on a brake dyna-
mometer.
Braking maneuvers triggered automatically
by ESP
®may seriously damage the brake sys-
tem.
!Vehicles with 4MATIC: as the ESP®sys-
tem operates automatically, the engine and
the ignition system must be switched off
(SmartKey in position 0or 1in the ignition
lock or Start/Stop button in position 0or 1)
when:
Rtesting the parking brake on a brake dyna-
mometer.
Ryou intend to have the vehicle towed with
one of the axles raised.
Braking maneuvers triggered automatically
by ESP
®may seriously damage the brake sys-
tem.
All checks and maintenance work on the brake
system must be carried out at a qualified spe-
cialist workshop.
Have brake pads installed and brake fluid
repla
ced at a qualified specialist workshop.
If the brake system has only been subject to
moderate loads, you should test the functional-
ity of your brakes at regular intervals. To do so,
press firmly on the brake pedal when driving at a
high speed. This improves the grip of the brake
pads.
You can find a description of Brake Assist (BAS)
on (
Ypage 65) or of BAS PLUS on (Ypage 65). The braking characteristics of the vehicle can be
seriously impaired if:
Rbrake pads other than those recommended
are installed
Rthe recommended brake fluid is not used
Safe braking can no longer be guaranteed.
AMG high-performance and ceramic
brakes
The high-performance brake system is only
installed on the Mercedes-AMG
CLS 63 S 4MATIC model.
The AMG brake systems are designed for heavy
loads. This may lead to noise when braking. This
will depend on:
RSpeed
RBraking force
REnvironmental conditions, such as tempera-
ture and humidity
The wear of individual components of the brake
system, such as the brake pads/linings or brake
discs, depends on the individual driving style
and operating conditions.
For this reason, it is impossible to state a mile-
age that will be valid under all circumstances. An aggressive driving style will lead to high wear.
You can obtain further information about this
from your authorized Mercedes-Benz Center.
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.
Keep this in mind, and adapt your driving and
braking accordingly during this break-in period.
Excessive heavy braking results in correspond-
ingly high brake wear. Observe the brake wear
warning lamp in the instrument cluster and note
any brake status messages in the multifunction
display. Especially for high performance driving,it is important to maintain and have the brake
system checked regularly.

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 may be lowered if you press the sus-
pension setting selector button or the AMG but-
ton. The vehicle also lowers if it is stationary.
!If Sport or Sport + suspension tuning has
been selected, the vehicle's ground clearance
decreases. Make sure that no objects
become trapped or that the vehicle does not
become damaged, for example, on the curb.
iThe vehicle level may change visibly at the
rear axle if you park the vehicle and the out-
side temperature changes. If the temperature
drops, the vehicle level lowers; with an
increase in temperature, the vehicle level
rises.
Changing the rear axle ride height
This function is only available on the Mercedes-
AMG CLS 63 4MATIC.
The vehicle level at the rear axle depends on the
selected suspension mode and the vehicle
speed.
The vehicle level at the rear axle changes while
driving depending on which suspension mode is
selected:
RComfort: +0.4 in (+10 mm)
RSport + and Sport: -0.6 in (-15 mm)
When changing from Comfort to Sport or Sport
+, the rear axle is lowered by approximately
1.0 in (25 mm). When changing from Sport or
Sport + to Comfort, the rear axle is raised by
approximately 1.0 in (25 mm). This level change
also takes place when the vehicle is stationary.
If you drive faster than 105 mph (170 km/h) , the
rear axle level is set to a middle level. This
increases driving safety and reduces air resist-
ance. If you then drive slower than 93 mph
(150 km/h), the level of the rear axle is again
adjusted to correspond to the selected suspen-
sion mode.
Load compensation
The vehicle can compensate differences in the
vehicle level by raising or lowering the rear axle.
This is the case, for example, if people get out or
if luggage is being loaded.
Load c
ompensation takes place if:
Ra door or the trunk lid is opened
Rthe parked vehicle is unlocked
For larger level changes, the engine must be
running.

ATTENTION ASSIST
General notes
ATTENTION ASSIST helps you during long,
monotonous journeys, such as on highways. It is
active in the 37 mph (60 km/h)to 125 mph
(200 km/h) range. If ATTENTION ASSIST
detects typical indicators of fatigue or increas-
ing lapses in concentration on the part of the
driver, it suggests taking a break.
Important safety notes
ATTENTION ASSIST is only an aid. It might not
always recognize fatigue or increasing inatten-
tiveness in time or fail to recognize them at all.
The system is not a substitute for a well-rested
and attentive driver.
The functionality of ATTENTION ASSIST is
restricted and warnings may be delayed or not
occur at all:
Rif the length of the journey is less than approx-
imately 30 minutes
Rif the road condition is poor, e.g. if the surface
is uneven or if there are potholes
Rif there is a strong side wind
Rif you have adopted a sporty driving style with
high cornering speeds or high rates of accel-
eration
Rif you are predominantly driving at a speed
below 37 mph (60 km/h) or above 124 mph
(200 km/h)
Rif you are driving with the DISTRONIC PLUS
Steering Assist activated
Rif the time has been set incorrectly
Rin active driving situations, such as when you
change lanes or change your speed The attention level evaluation is deleted and
restarts when the journey is continued, if:
Ryou switch off the engine
Ryou take off your seat belt and open the driv-
er's door, e.g. for a change of drivers or to
take a break
