ABS
The Antilock Brake System (ABS) regulates
the brake pressure so that the wheels do
not lock during braking. This allows you to
maintain the ability to steer your vehicle.
The ABS is functional above a speed of ap-
proximately 5 mph (8 km/h) independent
of road surface conditions.
On slippery road surfaces, the ABS will re-
spond even to light brake pressure.
The - indicator lamp in the instrument
cluster (
page 28) comes on when you
switch on the ignition (
page 370). It goes
out when the engine is running.
Warning!
G
The following factors increase the risk of ac-
cidents:

Excessive speed, especially in turns


Wet and slippery road surfaces


Following another vehicle too closely
The driving safety systems described in this
section cannot reduce these risks or pre-
vent the natural laws of physics from acting
on the vehicle.
Always adapt your driving style to the pre-
vailing road and weather conditions and
keep a safe distance to other road users and
objects on the street.
i
In winter operation, the maximum effective-
ness of the ABS, Adaptive Brake, BAS,
BAS Plus*, EBP, ESP
® and 4MATIC is only
achieved with winter tires (
page 610), or snow
chains as required.
Warning!
G
Do not pump the brake pedal. Use firm,
steady brake pedal pressure instead. Pump-
ing the brake pedal defeats the purpose of
the ABS and significantly reduces braking
effectiveness.

Switching on Rear View Camera
Switch on the ignition (
page 370).

Switch on COMAND (
page 87).

Move gear selector lever to reverse
gearR.
The COMAND display will show the
area behind the vehicle with guide
lines.
Warning!
G
Make sure no persons or animals are in the
area in which you are maneuvering. You
could otherwise injure them.Warning!
G
The Rear View Camera may not function if:

the trunk lid is not completely closed


it is raining or snowing heavily, or if
there is thick fog


in a very dark area


the camera is exposed to very strong
white light (white stripes may appear on
the COMAND display)


the surrounding area is lit with fluores-
cent light (the COMAND display can
flicker)


outside temperatures are very high (lens
condensation)


there is a sudden change in tempera-
ture, for example when you drive out of
the cold into a heated garage in winter
(lens condensation)


the camera lens is dirty or covered, see
“Cleaning the Rear View Camera* lens”
(page 621)


the rear of your vehicle is damaged. In
this case, have the position and setting
of the camera checked by a qualified
technician. Contact an authorized
Mercedes-Benz Center.
Do not use the Rear View Camera if the
roads are icy, slippery or covered with snow.
The vehicle could slip causing the actual ve-
hicle position to deviate from the one shown
on the COMAND display.
This may cause injury to you or others, or
damage the vehicle or objects.
Mounting tires/rims of other specification
than the original equipment tires/rims may
impair the function of the Rear View Cam-
era. Contact an authorized Mercedes-Benz
Center.
Warning!
G
Use of Rear View Camera can be dangerous
if you are color-blind or have impaired color
vision.
Only use Rear View Camera if you can see
and distinguish all colored guide lines shown
by Rear View Camera on the COMAND dis-
play.i
The Rear View Camera must be activated in
the instrument cluster control system in order
for it to be switched on (
page 303).

564 OperationDriving instructionsTire traction
The safe speed on a wet, snow covered or
icy road is always lower than on a dry road.
You should pay particular attention to the
condition of the road whenever the outside
temperatures are close to the freezing
point.Mercedes-Benz recommends winter tires
(
page 610) with a minimum tread depth
of approximately
1/6in (4 mm) on all four
wheels for the winter season to ensure
normal balanced handling characteristics.
On packed snow, they can reduce your
stopping distance compared to summer
tires.
Stopping distance, however, is still consid-
erably greater than when the road is not
covered with snow or ice. Exercise appro-
priate caution.
Tire speed rating
Regardless of the tire speed rating, local
speed limits should be obeyed. Use pru-
dent driving speeds appropriate to prevail-
ing conditions.
Warning!
G
If ice has formed on the road, tire traction
will be substantially reduced. Under such
weather conditions, drive, steer and brake
with extreme caution.
!
Avoid spinning of a drive wheel. This may
cause serious damage to the drivetrain which is
not covered by the Mercedes-Benz Limited War-
ranty.
Warning!
G
Even when permitted by law, never operate
a vehicle at speeds greater than the maxi-
mum speed rating of the tires.
Exceeding the maximum speed for which
tires are rated can lead to sudden tire fail-
ure, causing loss of vehicle control and pos-
sibly resulting in an accident and/or serious
personal injury and possible death, for you
and for others.

565 Operation
Driving instructions
An electronic speed limiter prevents your
vehicle from exceeding a speed of

All models except S 63 AMG and
S65AMG:
130 mph (210 km/h)


S 63 AMG:
S 65 AMG:
155 mph (250 km/h)


S 63 AMG with Performance Package*:
S 63 AMG with increased top speed*:
S 65 AMG with increased top speed*:
186 mph (300 km/h)
The factory equipped tires on your vehicle
may have a tire speed rating above the
maximum speed permitted by the elec-
tronic speed limiter.
Make sure your tires have the required tire
speed rating as specified for your vehicle in
the “Technical data” section (
page 754),
for example when purchasing new tires.
For information on how to identify the tire
speed rating on a tire’s sidewall, see “Tire
size designation, load and speed rating”
(
page 598).If you are uncertain about the correct read-
ing of the information given on a tire’s side-
wall, any authorized Mercedes-Benz
Center will be glad to assist you.
Winter driving instructions
The most important rule for slippery or icy
roads is to drive sensibly and to avoid
abrupt acceleration, braking and steering
maneuvers. Do not use the cruise control
or DISTRONIC Plus* system under such
conditions.
When the vehicle is in danger of skidding,
move gear selector lever to neutral
positionN. Try to keep the vehicle under
control by corrective steering action.Road salts and chemicals can adversely af-
fect braking efficiency. Increased pedal
force may become necessary to produce
the normal braking effect.
Depressing the brake pedal periodically
when traveling at length on salt-strewn
roads can bring road-salt impaired braking
efficiency back to normal.
If the vehicle is parked after being driven
on salt-treated roads, the braking efficien-
cy should be tested as soon as possible af-
ter driving is resumed.i
For information on speed ratings for winter
tires, see (
page 601) and (
page 610).
i
For information on driving with snow chains,
see “Snow chains” (
page 611).
Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of control loss.

582 OperationTires and wheelsContact an authorized Mercedes-Benz
Center for information on tested and
recommended rims and tires for summer
and winter operation. They can also offer
advice concerning tire service and
purchase.
Important guidelines

Only use sets of tires and rims of the
same type and make.


Tires must be of the correct size for the
rim.


Break in new tires for approximately
60 miles (100 km) at moderate
speeds.


Regularly check the tires and rims for
damage. Dented or bent rims can
cause tire inflation pressure loss and
damage to the tire beads.


If vehicle is heavily loaded, check tire
inflation pressure and correct as
required.


Do not allow your tires to wear down
too far. Adhesion properties on wet
roads are sharply reduced at tread
depths of less than
1/8in (3 mm).


When replacing individual tires, you
should mount new tires on the front
wheels first (on vehicles with
same-sized wheels all around).
Warning!
G
Replace rims or tires with the same designa-
tion, manufacturer and type as shown on the
original part. Contact an authorized
Mercedes-Benz Center for further informa-
tion. If incorrectly sized rims and tires are
mounted:

The wheel brakes or suspension
components can be damaged.


The operating clearance of the wheels
and the tires may no longer be correct.
Warning!
G
Worn, old tires can cause accidents. If the
tire tread is worn to minimum tread depth,
or if the tires have sustained damage, re-
place them.
When replacing rims, only use genuine
Mercedes-Benz wheel bolts specified for the
particular rim type. Failure to do so can
result in the bolts loosening and possibly an
accident.
Retreaded tires are not tested or recom-
mended by Mercedes-Benz, since previous
damage cannot always be recognized on re-
treads. The operating safety of the vehicle
cannot be assured when such tires are used.
