Driving and pa rking

When using an emergency spare wheel orspare wheel of a different size, you must notexceed the maximum speed of 50 mph(80 km/h).
Snow chains must not be mounted on emer-gency spare wheels.
General notes
You can ask for information regarding permit-ted emergency spare wheels at an authorizedMercedes-Benz Center.
You should regularly check the pressure of theemergency spare wheel, particularly prior tolong trips, and correct the pressure as neces-sary (Ypage 270). The value on the wheel isvalid.
An emergency spare wheel may also be moun-ted against the direction of rotation. Observethe time restriction on use as well as thespeed limitation specified on the emergencyspare wheel.
Replace the tires after six years at the latest,regardless of wear. This also applies to theemergency spare wheel.
When you are driving with the collapsiblespare wheel mounted, the tire pressure losswarning system or the tire pressure monitorcannot function reliably. Only restart the tirepressure loss warning system or tire pressuremonitor when the defective wheel has beenreplaced with a new wheel.
Vehicles with tire pressure monitor:aftermounting an emergency spare wheel, the sys-tem may still display the tire pressure of theremoved wheel for a few minutes. The valuedisplayed for the mounted emergency sparewheel is not the same as the current tire pres-sure of the emergency spare wheel.
Removing the emergency spare
wheel
Vehicles with a collapsible spare
wheel
The collapsible spare wheel can be found inthe stowage well under the trunk floor(Ypage 227).
XTurn retaining screwDcounter-clockwiseand remove it.

Always observe the instructions and safetynotes in the "Mounting a wheel" section(Ypage 289).
Stowing the emergency spare wheel
!Only place the collapsible spare wheel inthe vehicle when it is dry. Otherwise, mois-ture may get into the vehicle.
Take the following steps to stow a used col-lapsible spare wheel. Otherwise, the collapsi-ble spare wheel will not fit in the trunk in theintended manner. Mercedes-Benz recom-mends that you have this work carried out at aqualified specialist workshop.
XUnscrew the valve cap from the valve.
XIf possible, unscrew the valve insert fromthe valve and release the air.Fully deflating the tires can take a fewminutes.
XScrew the valve insert back into the valve.
XScrew the valve cap back on.
XPull the protective sheet provided with thespare wheel over the collapsible sparewheel.
XStow the collapsible spare wheel in theemergency spare wheel well under thetrunk.
XUse the retaining screw to pierce the pro-tective sheet and fasten the collapsiblespare wheel in place.
