Cleaning the seat covers
General notes
!
Do not use microfiber cloths to clean
genuine leather, artificial leather or
DINAMICA covers. If used often, these can
damage the cover.
i Note that regular care is essential to
ensure that the appearance and comfort of
the covers is retained over time.
Genuine leather seat covers
Leather is a natural product.
It exhibits natural surface characteristics, for
example:
R differences in the texture
R signs of stretching and marking
R slight nuances of color
These are characteristics of leather and not
material defects.
! To retain the natural appearance of the
leather, observe the following cleaning
instructions:
R Clean genuine leather covers carefully
with a damp cloth and then wipe the
covers down with a dry cloth.
R Make sure that the leather does not
become soaked. It may otherwise
become rough and cracked.
R Only use leather care agents that have
been tested and approved by Mercedes-
Benz. You can obtain these from a
qualified specialist workshop.
Seat covers of other materials
! Observe the following when cleaning:
R Clean artificial leather covers with a cloth
moistened with a solution containing
1% detergent (e.g. dish washing liquid).
R Clean cloth covers with a microfiber
cloth moistened with a solution
containing 1% detergent (e.g. dish
washing liquid). Rub carefully and always
wipe entire seat sections to avoid leaving
visible lines. Leave the seat to dry afterwards. Cleaning results depend on
the type of dirt and how long it has been
there.
R Clean Alcantara® covers with a damp
cloth. Make sure that you wipe entire
seat sections to avoid leaving visible
lines.
Cleaning the seat belts G
WARNING
Seat belts can become severely weakened if
bleached or dyed. This could cause the seat
belts to tear or fail, for instance, in the event
of an accident. This poses an increased risk
of injury or fatal injury.
Never bleach or dye the seat belts.
! Do not clean the seat belts using chemical
cleaning agents. Do not dry the seat belts
by heating at temperatures above 176 ‡

Important safety notes
G
WARNING
The rear axle locks when:
R the engine is not running
R the engine stalls while the vehicle is being
towed
R there is a malfunction in the power supply
or the vehicle's electrical system
There is a risk of an accident.
In the event of a breakdown, you should
always have the vehicle transported. G
WARNING
If the brake system or power steering is
malfunctioning and your vehicle is then towed
away, significantly more effort may be
required to steer and brake than is normally
required. There is a risk of an accident.
In such cases, use a tow bar. Before towing,
make sure that the steering moves freely. G
WARNING
If the weight of the vehicle to be towed or tow-
started is greater than the permissible gross
weight of your vehicle:
R the towing eye could detach itself
R the vehicle/trailer combination could
rollover.
There is a risk of an accident.
When towing or tow-starting another vehicle,
its weight should not be greater than the
permissible gross weight of your vehicle. !
Use the SmartKey instead of the Start/
Stop button when towing the vehicle.
Start the engine and keep it running. Turn
the SmartKey to position 2in the ignition.
Set the transmission to Nusing the E-
SELECT lever. Make sure that you then
leave the SmartKey in position 2.
Check the transmission position in the
instrument cluster.
! Make sure that the electric parking brake
is released. If the electric parking brake is
faulty, visit a qualified specialist workshop.
Mercedes-Benz recommends that you use
an authorized Mercedes-Benz Center for
this purpose.
! When towing, pull away slowly and
smoothly. If the tractive power is too high,
the vehicles could be damaged.
! Only secure the tow rope or tow bar at the
towing eyes. Otherwise, the vehicle could
be damaged.
! Do not use the towing eyes for recovery
purposes as this could damage the vehicle.
If in doubt, recover the vehicle with a crane.
! The vehicle can be towed a maximum of
30 miles (50km). The towing speed of
30 mph (50 km/h) must not be exceeded.
If the vehicle has to be towed more than
30 miles (50km), the entire vehicle must be
raised and transported.
! Do not tow with sling-type equipment.
This could damage the vehicle. 242

Information on driving
R If the vehicle is heavily loaded, check the
tire pressures and correct them if
necessary.
R While driving, pay attention to vibrations,
noises and unusual handling
characteristics, e.g. pulling to one side.
This may indicate that the wheels or tires
are damaged. If you suspect that a tire is
defective, reduce your speed immediately.
Stop the vehicle as soon as possible to
check the wheels and tires for damage.
Hidden tire damage could also be causing
the unusual handling characteristics. If you
find no signs of damage, have the wheels
and tires checked at a qualified specialist
workshop.
R When parking your vehicle, make sure that
the tires do not get deformed by the curb
or other obstacles. If it is necessary to drive 248
OperationWheels and tires

Bar indicator
0043for tread wear is integrated
into the tire tread.
Treadwear indicators (TWI) are required by
law. Six indicators are positioned on the tire
tread. They are visible once the tread depth
is approximately 00CDin (1.6 mm). If this is the
case, the tire is so worn that it must be
replaced. Selecting, mounting and replacing
tires
R Only mount tires and wheels of the same
type and make.
R Only mount tires of the correct size onto
the wheels.
R Break in new tires at moderate speeds for
the first 60 miles (100 km). They only reach
their full performance after this distance.
R Do not drive with tires which have too little
tread depth, as this significantly reduces
the traction on wet roads (hydroplaning).
R Replace the tires after six years at the
latest, regardless of wear. Winter operation
General notes
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
Observe the notes in the "Changing a wheel"
section (Y page 268). Driving with summer tires
At temperatures below 45 ‡(+7 †), summer
tires experience a considerable loss in
elasticity and therefore traction and braking
power. Change the tires on your vehicle to
M+S tires. Using summer tires at very cold
temperatures could cause cracks to form,
thereby damaging the tires permanently.
Mercedes-Benz cannot accept responsibility
for this type of damage. M+S tires
G
WARNING
M+S tires with a tire tread depth of less than
00CF in (4 mm) are not suitable for use in winter
and do not provide sufficient traction. There
is a risk of an accident.
M+S tires with a tread depth of less than 00CF
in (4 mm) must be replaced immediately.
At temperatures below 45 ‡ (+7 †), use
winter tires or all-season tires. Both types of
tire are identified by the M+S marking.
Only winter tires bearing the 004Dsnowflake
symbol in addition to the M+S marking
provide the best possible grip in wintry road
conditions. Only these tires will allow driving
safety systems such as ABS and ESP ®
to
function optimally in winter. This is because
these tires were specifically developed for
driving in snow.
Use M+S tires of the same make and tread on
all wheels to maintain safe handling
characteristics.
Always observe the maximum permissible
speed specified for the M+S tires you have
mounted.
When you have mounted the M+S tires:
X Check the tire pressures (Y page 251).
X Restart the tire pressure monitor
(Y page 257). 250

i Tire data is vehicle-specific and may
deviate from the data in the example.
General: depending on the manufacturer's
standards, the size imprinted in the tire wall
may not contain any letters or may contain
one letter that precedes the size description.
If there is no letter preceding the size
description (as shown above): these are
passenger vehicle tires according to
European manufacturing standards.
If "P" precedes the size description: these are
passenger vehicle tires according to U.S.
manufacturing standards.
If "LT" precedes the size description: these
are light truck tires according to U.S.
manufacturing standards.
If "T" precedes the size description: these are
compact emergency spare wheels at high tire
pressure, to be used only temporarily in an
emergency.
Tire width: tire width0043shows the nominal
tire width in millimeters. Aspect ratio:
aspect ratio0044is the size ratio
between the tire height and tire width and is
shown in percent. The aspect ratio is
calculated by dividing the tire width by the tire
height.
Tire code: tire code0087specifies the tire type.
"R" represents radial tires; "D" represents
diagonal tires; "B" represents diagonal radial
tires.
Optionally, tires with a maximum speed of
over 149 mph (240 km/h) may have "ZR" in
the size description depending on the
manufacturer (e.g. 245/40 ZR 18).
Rim diameter: rim diameter0085is the
diameter of the bead seat, not the diameter
of the rim flange. The rim diameter is
specified in inches (in).
Load-bearing index: load-bearing index0083
is a numerical code that specifies the
maximum load-bearing capacity of a tire.
Do not overload the tires by exceeding the
specified load limit. The maximum
permissible load can be found on the
vehicle's Tire and Loading Information
placard on the B-pillar on the driver's side
(Y page 258).
Example:
Load-bearing index 91 indicates a maximum
load of 1,356 lb (615 kg) that the tires can
bear. For further information on the maximum
tire load in kilograms and lbs, see
(Y page 265).
For further information on the load bearing
index, see "Load index" (Y page 265).
Speed rating: speed rating0084specifies the
approved maximum speed of the tire.
Regardless of the speed rating, always
observe the speed limits. Drive carefully and
adapt your driving style to the traffic
conditions. All about wheels and tires
