pulling away on wet or slippery roads. ESP®
can also stabilize the vehicle during braking.
ETS (Electronic Traction System)
iObserve the "Important safety notes" sec-
tion (
Ypage 61).
ETS traction control is part of ESP
®.
ETS brakes the drive wheels individually if
they spin. This enables you to pull away and
accelerate on slippery surfaces, for example
if the road surface is slippery on one side. In
addition, more drive torque is transferred to
the wheel or wheels with traction.
ETS remains active when you deactivate
ESP
®.
iMercedes-AMG vehicles: your vehicle
may be equipped with 20-inch tires on the
rear axle. After changing to 19 inch wheels,
ETS may intervene noticeably earlier during
the first few kilometers. After approx-
imately 10 km ETS will function as usual
again. Information on the dimensions and
types of wheels and tires for your vehicle
can be found in the "Wheel/tire combina-
tions" section (
Ypage 335).
Important safety notes
GWARNING
If ESP
®is malfunctioning, ESP®is unable to
stabilize the vehicle. Additionally, further driv-
ing safety systems are deactivated. This
increases the risk of skidding and an accident.
Drive on carefully. Have ESP
®checked at a
qualified specialist workshop.
When towing the vehicle with the rear axle
raised, observe the notes on ESP®
(Ypage 303).
ESP
®is only deactivated if the åwarning
lamp is lit continuously.
If the ÷ warning lamp and the åwarn-
ing lamp are lit continuously, ESP
®not avail-
able due to a malfunction. Observe the information on warning lamps
(
Ypage 245) and display messages which
may be shown in the instrument cluster
(
Ypage 212).
iOnly use wheels with the recommended
tire sizes. Only then will ESP®function
properly.
Characteristics of ESP®
General information
If the ÷ ESP
®warning lamp goes out
before beginning the journey, ESP®is auto-
matically active.
If ESP
®intervenes, the ÷ESP®warning
lamp flashes in the instrument cluster.
If ESP
®intervenes:
XDo not deactivate ESP®under any circum-
stances.
XOnly depress the accelerator pedal as far as
necessary when pulling away.
XAdapt your driving style to suit the prevail-
ing road and weather conditions.
ECO start/stop function
The ECO start/stop function switches the
engine off automatically when the vehicle
stops moving. The engine starts automati-
cally when the driver wants to pull away again.
ESP
®remains in its previously selected sta-
tus. Example: if ESP®was deactivated before
the engine was switched off, ESP®remains
deactivated when the engine is switched on
again.
Deactivating/activating ESP®(except
Mercedes ‑AMG vehicles)

larly in the event of sudden braking or a sud-

Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey.

GWARNING
When opening or closing the roof, body parts
could be trapped by, for example, the roof
mechanism, trunk lid or side windows. There
is a risk of injury.
When raising or lowering the roof, make sure
that no body parts are in the vicinity of moving
components. If someone becomes trapped,
release the button.

Traction
Traction is the result of friction between the
tires and the road surface.
Treadwear indicators
Narrow bars (tread wear bars) that are dis-
tributed over the tire tread. If the tire tread is
level with the bars, the wear limit ofáin
(1.6 mm) has been reached.
Occupant distribution
The distribution of occupants in a vehicle at
their designated seating positions.
Total load limit
Rated cargo and luggage load plus
68 kilograms (150 lb) multiplied by the num-
ber of seats in the vehicle.
Changing a wheel
Flat tire
The "Breakdown assistance" section
(
Ypage 291) contains information and notes
on how to deal with a flat tire. Information on driving with MOExtended tires in the event of
a flat tire can be found under "MOExtended
tires (tires with run-flat characteristics"
(
Ypage 291).
Rotating the wheels
GWARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
the wheels or tires have different dimensions. The wheel brakes or suspension components
may also be damaged. There is a risk of acci-
dent.
Rotate front and rear wheels only if the wheels and tires are of the same dimensions.
!On vehicles equipped with a tire pressure
monitor, electronic components are loca-
ted in the wheel. Tire-mounting tools should not be used
near the valve. This could damage the elec-
tronic components.
Only have tires changed at a qualified spe-
cialist workshop.
Always pay attention to the instructions and
safety notes when changing a wheel
(
Ypage 331).
The wear patterns on the front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before a clear wear pattern
has formed on the tires. Front tires typically
wear more on the shoulders and the rear tires
in the center.
On vehicles that have the same size front and
rear wheels, you can rotate the wheels
according to the intervals in the tire manu-
facturer's warranty book in your vehicle docu-
ments. If no warranty book is available, the
tires should be rotated every 3,
000 to
6,000 miles (5,000 to 10,000 km). Depending on tire wear, this may be required earlier. Do
not change the direction of wheel rotation.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is rotated. Check the tire pressure and, if nec-
essary, restart the tire pressure loss warning
system or the tire pressure monitor.
Direction of rotation
Tires with a specified direction of rotation
have additional benefits, e.g. if there is a risk
of hydroplaning. These advantages can only
be gained if the tires are installed correspond-
ing to the direction of rotation.
An arrow on the sidewall of the tire indicates
its correct direction of rotation.
Storing wheels
Store wheels that are not being used in a cool,
dry and preferably dark place. Protect the
tires from oil, grease, gasoline and diesel.

Emergency spare wheel
Important safety notes
GWARNING
The wheel or tire size as well as the tire type of the spare wheel or emergency spare wheel
and the wheel to be replaced may differ.
Mounting an emergency spare wheel may
severely impair the driving characteristics.
There is a risk of an accident.
To avoid hazardous situations:
Radapt your driving style accordingly and
drive carefully.
Rnever mount more than one spare wheel or
emergency spare wheel that differs in size.
Ronly use a spare wheel or emergency spare
wheel of a different size briefly.
Rdo not switch ESP®off.
Rhave a spare wheel or emergency spare
wheel of a different size replaced at the
nearest qualified specialist workshop.
Observe that the wheel and tire dimensions
as well as the tire type must be correct.
When using an emergency spare wheel or
spare wheel of a different size, you must not
exceed the maximum speed of 50 mph
(80 km/h).
Snow chains must not be mounted on emer-
gency spare wheels.
General notes
You should regularly check the pressure of
the emergency spare wheel, particularly prior
to long trips, and correct the pressure as nec-
essary (
Ypage 311). The applicable value is
3Use of snow chains not permitted. Observe the notes in the "Snow chains" section.
