MERCEDES-BENZ SLS AMG GT COUPE 2015 C197 Owner's Manual

GVWR (Gross Vehicl
eWeight Rating)
The GVWR is the maximu mpermitted gross
weight of the fullyl oaded vehicle (weight of
the vehicle including all accessories, occu-
pants, fuel,l uggage and the drawbar nose-
weight if applicable).T he gross vehicle weight
rating is specified on the vehicle identification plate on the B-pilla ronthe driver's side.
Maximum loaded vehicle weight
The maximu mweight is the sum of the curb
weight of the vehicle ,the weight of the acces-
sories ,the total loadl imitand the weight of
the optional equipment installed at the fac-
tory.
Kilopascal (kPa)
Metric unit for tire pressure. 6.9 kPa is the
equivalent of 1psi.A nother unit for tire pres-
sure is bar. There are 100 kilopascals (kPa) to
1b ar.
Load index
In addition to the load-bearing index, the load index may alsobei mprinted on the sidewallof
the tire. This specifies the load-bearing capa-
city more precisely.
Curb weight
The weight of avehicle with standard equip-
ment including the maximu mcapacity of fuel,
oil and coolant. It alsoi ncludes the air-condi-
tioning system and optional equipment if
these are installed in the vehicle ,but does not
includ epassengers or luggage.
Maximum load rating
The maximu mloadr ating in kilograms or
pounds is the maximu mweight for which a
tire is approved.
Maximum permissible tire pressure
Maximu mpermissibl etire pressure for one
tire.
Maximum load on one tire
Maximu mloadono ne tire. This is calculated
by dividing the maximu maxle loadofo ne axle
by two. PSI (pounds per square inch)
As
tandard unit of measure for tire pressure.
Aspec tratio

width in percent.
tire pressure
This is pressure inside the tire applying an
outward force to each square inch of the tire's surface. The tire pressure is specified in
pounds per square inch (psi), in kilopascal
(kPa) or in bar. The tire pressure shoul donly
be corrected when the tires are cold. For this,
the vehicle must have been stationary for at
least three hours or not have traveled more
than 1.6 km (1 mile)int his time.
Tire pressure of coldt ires
The tires are cold:
R if the vehicle has been parked without
direct sunlight on the tires for at least three
hours and
R if the vehicle has not been driven more than
1m ile (1.6 km)
Tread
The part of the tire that comes into contact
with the road.
Bead
The tire beade nsures that the tire sits
securel yonthe wheel. There are severa lsteel
wiresint he beadtop revent the tire from
coming loose from the wheelr im.
Sidewall
The part of the tire betwee nthe tread and the
bead.
Weight of optional extras
The combined weight of those optional extras
that weigh more than the replaced standard
part and more than 2.3 kilograms (5 lbs).
These optional extras, such as high-perform-
ance brakes, level control, aroof rack or a
high-performance battery, are not included in Alla

Using lug wrench 0043,loosen the bolts on
the wheel you wish to change by abouto ne
full turn. Do not unscrew the wheel bolts
completely.
The mounting for the jack is centered
between the front and rear wheel housings
(arrow). !
The jack is designed exclusively for jack-
ing up the vehicle at the jacking points.
Otherwise, your vehicle could be damaged. X
Position jack 0087at jacking point 0044. Example
X Make sure that the base of the jack is posi-
tioned directly under jacking point 0044.
X Turn crank 0085clockwise until jack 0087sits
completely on jacking point 0044and the
base of the jack lies evenly on the ground.
X Turn crank 0085until the tire is raised amax-
imum of 1.2 inches (3 cm) off the ground.
Removing awheel X
Unscrew the uppermost wheel bolt com-
pletely.
X Screw alignment bolt 0083into the thread
instead of the wheel bolt.
X Unscrew the remaining wheel bolts fully.
! Do not place wheel bolts in sand or on a
dirty surface. The bolt and wheel hub
threads could otherwise be damagedw hen

WARNING
Oiled or greased wheel bolts or damaged
wheel bolts/hub threads can cause the wheel bolts to come loose. As aresult, you could
lose awheel while driving. There is arisk of
accident.
Never oil or grease wheel bolts. In the event of damage to the threads, contact aqualified
specialist workshop immediately. Have the
damaged wheel bolts or hub threads
replaced/renewed. Do not continue driving. G
WARNING
If you tighten the wheel bolts or wheel nuts
when the vehicle is raised, the jack could tip
over. There is arisk of injury.
Only tighten the wheel bolts or wheel nuts
when the vehicle is on the ground.
Always pay attention to the instructions and
safety notes in the "Changing awheel" sec-
tion (Y page 270).
Only use wheel bolts that have been designed for the wheel and the vehicle. For safety rea-
sons, Mercedes-Benz recommends that you
only use wheel bolts which have been
approved for Mercedes-Benz vehicles and the
respective wheel. 0043

General notes
! For safety reasons, Mercedes-Benz rec-
ommends that you only use tires and
wheels which have been approved by Mercedes-Benz specifically for your vehi-
cle.
These tires have been specially adapted for
use with the control systems, such as ABS
or ESP ®
,a nd are marked as follows:
R MO =Mercedes-Benz Original
R MOE =Mercedes-Benz Original Extended
(tires featuring run-flat characteristics)
R MO1 =Mercedes-Benz Original (only cer-
tain AMG tires)
Mercedes-Benz Original Extended tires
may only be used on wheels that have been
specifically approved by Mercedes-Benz.
Only use tires, wheels or accessories
tested and approved by Mercedes-Benz.
Certain characteristics, e.g. handling, vehi-
cle noise emissions or fuel consumption,
may otherwise be adversely affected. In
addition, when driving with aload, tire
dimension variations could cause the tires
to come into contact with the bodywork
and axle components. This could result in
damage to the tires or the vehicle.
Mercedes-Benz accepts no liability for
damage resulting from the use of tires,
wheels or accessories other than those
tested and approved.
Information on tires, wheels and approved
combinations can be obtained from any
qualified specialist workshop.
i The Tire and Load Information placard
with the recommended tire pressures is on the B-pillar on the driver's side. Further
information about driving at high speeds or driving with vehicle loads that are lighter
than the maximum vehicle load can be
found in the tire pressure table on the
inside of the fuel filler flap. Check tire pres- sures regularly, and only when the tires arecold. Comply with the maintenance recom-
mendation softhe tire manufacturer. These
are located in the vehicle document wallet.

pressures as well as tire pressures for spe-
cific driving situations, see (Y page 253). Wheel and tirec

Notes on the vehicle equipment –always
equipt he vehicle with:
R tires of the same size on agiven axle
(left/right)
R with the same type of tires on all wheels
at ag iven time (summer tires, winter
tires)
i The following pagesc
ontain information
on approved wheel rims and tire sizes for
equipping yourv ehicle with winter tires.
Winter tires are not available at the factory as standard equipment or optional extras.
If you wish to equipy ourv ehicle with
approved winter tires, you willa lso require,
in certain circumstances, wheel rims of an
appropriate size, as the sizes of approved
winter tires can deviate from those of
standard tires. This is dependent on the
model and the equipment installe datthe
factory.
The tires and wheel rims, as well as further information, can be obtained at aqualified
specialist workshop. 276
