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 rota-ted. Check the tire pressure and, if necessary,
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 hydro-
planing. These advantages can only be gained if
the tires are installed corresponding 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.
Mounting a wheel
Preparing the vehicle
XVehicle with emergency spare wheel:
when mounting the emergency spare wheel in
the event of a flat tire, follow the additional
notes on vehicle preparation under "Flat tire"
(
Ypage 315).
XStop the vehicle on solid, non-slippery and
level ground.
XApply the electric parking brake manually.
XUnload heavy luggage.
XBring the front wheels into the straight-ahead position.
XShift the transmission to position P.
XVehicles with the AIRMATIC package:
make sure that the normal vehicle level is
selected (
Ypage 183).
XSwitch off the engine.
XVehicles without KEYLESS-GO:remove the
SmartKey from the ignition lock.
XVehicles with KEYLESS-GO: open the driv-
er's door.
The on-board electronics now have status 0.
This is the same as the SmartKey having been
removed.
XVehicles with KEYLESS-GO: remove the
Start/Stop button from the ignition lock
(
Ypage 134).
XMake sure that the engine cannot be started
via your smartphone (Ypage 136).
XIf included in the vehicle equipment, remove
the tire-change tool kit from the vehicle.
XSafeguard the vehicle against rolling away.
iApart from certain country-specific varia-
tions, vehicles are not equipped with a tire-
change tool kit. For information on which
tools are required to perform a wheel change
on your vehicle, consult an authorized
Mercedes-Benz Center.
Necessary tire-changing tools can include, for example:
RJack
RWheel chock
RLug wrench
Securing the vehicle to prevent it from
rolling away
If your vehicle is equipped with a wheel chock, itcan be found in the tire-change tool kit
(
Ypage 315).
The folding wheel chock is an additional safety
measure to prevent the vehicle from rolling
away, for example when changing a wheel.
XFold both plates upwards :.
XFold out lower plate;.
XGuide the lugs on the lower plate fully into the
openings in base plate =.

Climate control system refrigerant
Important safety notes
The climate control system of your vehicle is fil-
led with refrigerant R ‑134a.
The instruction label regarding the refrigerant
type used can be found on the radiator cross
member.
!Only the refrigerant R ‑134a and the PAG oil
approved by Mercedes-Benz may be used.
The approved PAG oil may not be mixed with
