2018 MERCEDES-BENZ SLC ROADSTER wheel

must be positioned vertically, directly under
the jacking point of the vehicle.
!Only position the jack at the appropriate
jacking point of the vehicle. Otherwise, you
could damage the vehicle.
Observe the following when raising the vehicle:
RTo rais ethe vehicle, only use the vehicle-spe-
cific jack that has been tested and approved
by Mercedes-Benz. If used incorrectly, the
jack could tip over with the vehicler aised.
RThe jack is designed only to raiseand hold the
vehiclef oras hort time while awheelisb eing
changed. It must not be used for performing
maintenance work under the vehicle.
RAvoid changing the wheelonu phill and down-
hill slopes.
RBefore raising the vehicle, secure it from roll-
ing awa ybyapplying the parking brake and
inserting wheelc hocks. Do not disengage the
parking brake whilet he vehicleisraised.
RThe jack must be placed on afirm, flat and
non-slip surface. On aloose surface, alarge,
flat, load-bearing underlay must be used .Ona
slippery surface, anon-slip underlay must be
used ,e.g. rubber mats.
RDo not use wooden blocks or similar objects
as ajack underlay.O therwise, the jack willn ot
be abletoa chieve its load-bearing capacity
due to the restricted height.
RMake sure that the distance betweent he
underside of the tires and the ground does not
exceed 1.2 in (3 cm).
RNever place you rhands and feet under the
raised vehicle.
RDo not lie under the vehicle.
RDo not start the engine when the vehiclei s
raised.
RDo not open or close adoor or the trunk lid
when the vehicleisr aised.
RMake sure that no persons are present in the
vehiclewhen the vehicleisr aised.

wheely ou wish to change by abouto ne full
turn. Do not unscrew the bolts completely.
The jacking points are located just behind the
front wheelh ousings and just in front of the rear
wheelh ousings (arrows).
Vehicles with AMG equipment: the vehicle
has covers installed to protect the vehicleb ody
next to the jacking points on the outer sills.

Removing awheel
!Do not place wheel bolts in sand or on adirty
surface. The bolt and wheel hub threads could
otherwise be damaged when you screw them
in.
XUnscrew the uppermost wheel bolt com-
pletely.
XScrew alignment bolt :into the thread
instead of the wheel bolt.
XUnscrew the remaining wheel bolts fully.
XRemove the wheel.
Mounting anew wheel
GWARNING
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.
GWARNING
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 instruction sand
safety notes in the "Changing awheel" section
(
Ypage 280).
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.
!To prevent damage to the paintwork ,hold
the wheel securely against the wheel hub
while screwing in the first wheel bolt.

Wheel and tir ecombinations
You can ask for informatio nregardin gpermitted

Mercedes-Ben zCenter.
!For safety reasons, Mercedes-Ben zrecom-
men dsthat you only use tires and wheels
whichh ave been approvedbyM ercedes-Benz
specifically for your vehicle.
284Wheel and tir ecombinations
Wheels and tires

These tires have been specially adapted for
use with the control systems, such as ABS or
ESP
®,and are marked as follows:
RMO = Mercedes-Benz Original
RMOE = Mercedes-Benz Original Extended
(tires featuring run-flat characteristics)
RMO1 = Mercedes-Benz Original (only cer-
tain AMG tires)
Mercedes-Benz Original Extended tires may
only be used on wheels that have been spe-
cifically approved by Mercedes-Benz.
Only use tires, wheels or accessories tested
and approved by Mercedes-Benz.C ertain
characteristics, e.g. handling, vehicle noise
emissions or fuel consumption, may other-
wise 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 vehi- cle.
Mercedes-Benz accepts no liability for dam-
age 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 quali-
fied specialist workshop.
!Retreaded tires are neither tested nor rec-
ommended by Mercedes-Benz,s ince previ-
ous damage cannot alwaysbed etected on
retreaded tires. As aresult, Mercedes-Benz
cannot guarantee vehicle safety if retreaded
tires are mounted. Do not mount used tires if
you have no information about their previous
usage.
The recommended pressures for various oper-
ating conditions can be found:
Ron the Tire and Loading Information placard
on the B-pillar on the driver's side
Rin the tire pressure table on the fuel filler flap
Observe the notes on recommended tire pres-
sures under various operating conditions
(
Ypage 263).
Check tire pressures regularly, and only when
the tires are cold. Comply with the maintenance
recommendations of the tire manufacturer in
the vehicle document wallet. Notes on the vehicle equipment
–alwayse quip
the vehicle:
Rwith tires of the same size on agiven axle (left
and right)
Rwith the same type of tires at agiven time
(summer tires, winter tires, MOExtended
tires)
Exception: it is permissible to mount adiffer-
ent type or make in the event of aflat tire.
Observe t

he "MOExtended tires (tires with
run-flat characteristics)" section
(
Ypage 247).
Vehicles equipped with MOExtended tires are
not equipped with aTIREFIT kit at the factory. It
is therefor erecommended that you additionally
equip your vehicle with aTIREFIT kit if you mount
tires that do not feature run-flat characteristics,
e.g. winter tires. ATIREFIT kit may be obtained
from aqualified specialist workshop.
Emergency sparew heel
Important safety notes
GWARNING
The wheel or tire size as well as the tire type of the spare wheel or emergencys pare wheel
and the wheel to be replaced may differ.
Mountin ganemergencys pare wheel may
severely impair the driving characteristics.
There is arisk of an accident.
To avoid hazardous situations:
Radapt your driving style accordingly and
drive carefully.
Rnever mount more than one spare wheel or
emergencys pare wheel that differs in size.
Ronly useaspare wheel or emergencys pare
wheel of adifferent size briefly.
Rdo not switch ESP®off.
Rhave aspare wheel or emergencys pare
wheel of adifferent 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 emergencys pare wheel or spare
wheel of adifferent size, you must not exceed
the maximum speed of 50 mph (80 km/h).

General notes
You can as kfor information regarding permitted
emergency spare wheel satanauthorized
Mercedes-Benz Center.
You shoul dregularl ycheck the pressure of the
emergency spare wheel ,particularly prior to
long trips, and correct the pressure as neces-
sary (
Ypage 263). The value on the wheel is
valid.
An emergency spare wheel may also be moun-
ted against the direction of rotation. Observe
the time restriction on us easwellast he speed
limitation specified on the emergency spare
wheel.
Replace the tire saftersix years at the latest,
regardless of wear. Thisa lsoa pplies to the
emergency spare wheel.
Wheny ouare driving with the collapsibl espare
wheel mounted, the tire pressure loss warning
system or the tire pressure monitor canno tfunc-
tion reliably. Only restart the tire pressure loss
warning system or tire pressure monitor when
the defectiv ewheel hasb eenr eplaced with a
new wheel.
Vehicles with tire pressure monitor: after
mounting an emergency spare wheel ,the sys-
tem may stil ldisplay the tire pressure of the
removed wheel for afew minutes. The value dis-
played for the mounted emergency spare wheel
is not the same as the current tire pressure of
the emergency spare wheel.
