the SmartKey from the ignition lock.
X Vehicles with KEYLESS-GO: open the
driver's door. The on-board electronics have status 0, which is the same as the SmartKey having been removed.
X Vehicles with KEYLESS-GO: remove the
Start/Stop button from the ignition lock (Y page 307).
X All occupants must get out of the vehicle. Make sure that they are not endangered as they do so.
X Make sure that no one is near the danger
area while a wheel is being changed. Anyone who is not directly assisting in the wheel change should, for example, stand behind the barrier.
X Get out of the vehicle. Pay attention to
traffic conditions when doing so.
X Close the driver's door.
Rhave a spare wheel or emergency spare wheel of a different size replaced at the nearest qualified specialist workshop. Observe that the wheel and tire dimensions as well as the tire type must be correct.
i Vehicles without aspare wheel or
emergency spare wheel are not equipped with a tire-change tool kit at the factory. For more information on which tools are required to perform a wheel change on your vehicle, e.g. wheel chock, lug wrench or alignment bolt, consult an authorized Mercedes-Benz Center.
X Prepare the vehicle as described
(Y page 479).
X Remove the following items (depending on the vehicle's equipment) from the stowage well under the trunk floor:
Remergency spare wheel or spare wheel
Rwheel bolts for the spare wheel/
emergency spare wheel
480 Flat tire
Rvehicle tool kit
Rfolding wheel chock
Rjack
the wheel that is diagonally opposite the wheel you wish to change.
X Secure the vehicle to prevent it from rolling
away.
Securing the vehicle to prevent it from
rolling away
If your vehicle is equipped with a wheel chock, it can be found in the vehicle tool kit (Y page 478).
The folding wheel chock is an additional securing measure to prevent the vehicle from rolling away, for example when changing a wheel.
X Fold both plates upwards :. X Fold out lower plate ;.
Securing the vehicle on slight downhill gradients
X On downhill gradients: place chocks or other suitable items in front of the wheels of the front and rear axle.
Raising the vehicle
G WARNING If you do not position the jack correctly at the appropriate jacking point of the vehicle, the jack could tip over with the vehicle raised. There is a risk of injury.
Only position the jack at the appropriate jacking point of the vehicle. The base of the jack must be positioned vertically, directly under the jacking point of the vehicle.
X Guide the lugs on the lower plate fully into
the openings in base plate =.
The following must be observed when raising the vehicle:
Rto raise the vehicle, only use the vehicle-
specific jack that has been tested and approved by Mercedes-Benz. If used incorrectly, the jack could tip over with the vehicle raised.
Rthe jack is designed only to raise and hold the vehicle for a short time while a wheel is being changed. It is not suited for performing maintenance work under the vehicle.
Ravoid changing the wheel on uphill and
downhill slopes.
Rbefore raising the vehicle, secure it from
rolling away by applying the parking brake
Securing the vehicle on level ground
X On level ground: place chocks or other
suitable items under the front and rear of
Flat tire 481
and inserting wheel chocks. Never disengage the parking brake while the vehicle is raised.
Rthe jack must be placed on a firm, flat and
non-slip surface. On a loose surface, a large, load-bearing underlay must be used. On a slippery surface, a non-slip underlay must be used, e.g. rubber mats.
Rdo not use wooden blocks or similar
objects as a jack underlay. Otherwise, the jack will not be able to achieve its load- bearing capacity due to the restricted height.
RThe maximum clearance between the
underside of the tire and the ground must be 1.2 in (3 cm).
Rnever place your hands and feet under the
raised vehicle.
Rnever lie under the raised vehicle.
Rnever start the engine when the vehicle is
raised.
Rnever open or close a door or the trunk lid
when the vehicle is raised.
Rmake sure that no persons are present in
the vehicle when the vehicle is raised.
! The jack is designed exclusively for
jacking up the vehicle at the jacking points. Otherwise, your vehicle could be damaged.
X Position jack = at jacking point ;.
X Using lug wrench :, loosen the bolts on
the wheel you wish to change by about one full turn. Do not unscrew the bolts completely.
The jacking points are located just behind the wheel housings of the front wheels and just in front of the wheel housings of the rear wheels (arrows).
X Make sure that the base of the jack is
positioned directly under the jacking point. X Turn crank ? clockwise until jack = sits
completely on jacking point ; and the base of the jack lies evenly on the ground.
X Turn handle ? until the tire is 1.2 in
(3 cm) from the ground at most.

Removing a wheel
X Unscrew the uppermost wheel bolt
completely.
X Screw alignment bolt : into 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 damaged when you screw them in.
X Remove the wheel.
Mounting a new wheel
G WARNING Oiled or greased wheel bolts or damaged wheel bolts/hub threads can cause the wheel bolts to come loose. As a result, you could lose a wheel while driving. There is a risk of accident.
Never oil or grease wheel bolts. In the event of damage to the threads, contact a qualified 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 a risk 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 notices in "Changing a wheel" (Y page 521).
Only use wheel bolts that have been designed for the wheel and the vehicle. For safety reasons, Mercedes-Benz recommends that you only use wheel bolts which have been approved for Mercedes-Benz vehicles and the respective wheel.
Be sure to use the original-length wheel bolts when refitting the original wheel after it has been repaired.
Wheel bolts for: : All alloy wheels and the "Minispare"
emergency spare wheel for alloy wheels ; "Minispare" emergency spare wheel for
steel wheels
! Always use wheel bolts : to fit the
"Minispare" emergency spare wheel with light-alloy wheel. Using other wheel bolts when fitting the "Minispare" emergency spare wheel with light-alloy wheel could damage the brake system. Always use wheel bolts ; to fit the "Minispare" emergency spare wheel with steel wheel. Using other wheels when fitting the "Minispare" emergency spare wheel with steel wheel could damage the brake system.
X Clean the wheel and wheel hub contact
surfaces.
! To prevent damage to the paintwork, hold the wheel securely against the wheel hub while screwing in the first wheel bolt.

X Slide the emergency spare wheel onto the
alignment bolt and push it on.
X Tighten the wheel bolts until they are
finger-tight.
X Unscrew the alignment bolt.
X Tighten the last wheel bolt until it is finger-
tight.
G WARNING The wheels could work loose if the wheel nuts and bolts are not tightened to the specified tightening torque. There is a risk of accident.
Have the tightening torque immediately checked at a qualified specialist workshop after a wheel is changed.
Lowering the vehicle
G WARNING Tire pressure that is too high or too low can lead to a blowout of the mounted emergency spare wheel/spare wheel, particularly when driving with a heavy load and increasing speed. There is a risk of accident.
Check the tire pressure of the emergency spare wheel or spare wheel and adjust it. When doing so, observe the specified tire pressure.
X Turn the crank of the jack counter-
clockwise until the vehicle is once again standing firmly on the ground.
X Place the jack to one side.
X Tighten the wheel bolts evenly in a crosswise pattern in the sequence indicated (: to A). The tightening torque must be 110 lb-ft (150 Nm).
X Turn the jack back to its initial position and
store it together with the rest of the tire- change tool kit in the stowage well under the trunk floor.
i When you are driving with the emergency
spare wheel mounted, the tire pressure monitoring system cannot function reliably. Only restart the tire pressure monitoring system when the defective wheel has been replaced with a new wheel.
All wheels mounted must be equipped with functioning sensors. The defective wheel should no longer be in the vehicle.
MOExtended tires (tires with run-flat
properties)
With MOExtended tires (tires with run flat characteristics), you can continue to drive your vehicle even if there is a total loss of pressure in one or more tires.
484 Battery
MOExtended tires may only be used in conjunction with the activated tire pressure loss warning system or with the activated tire pressure monitoring system.
i When replacing one or all tires, make sure
that you only use tires marked MOExtended. Also ensure that they are of the specified size for the vehicle.
The driving distance in partially laden condition is approximately 50 miles (80 km), and approximately 18 miles (30 km) when fully loaded.
In addition to the vehicle load, the driving distance possible depends upon:
Rspeed
Rroad condition
Routside temperature
The driving distance possible in run-flat mode may be reduced by extreme driving conditions/maneuvers, or it can be increased through a moderate style of driving.
The maximum permissible distance which can be driven in run-flat mode is counted from the moment the tire pressure loss warning appears in the multifunction display.
Do not exceed a vehicle speed of 50 mph (80 km/h).
G WARNING When driving in emergency mode, the driving characteristics deteriorate, e.g. when cornering, accelerating quickly and when braking. There is a risk of an accident.
Do not exceed the stated maximum speed. Avoid abrupt steering and driving maneuvers, and driving over obstacles (curbs, potholes, off-road). This applies in particular to a laden vehicle.
Stop driving in emergency mode if:
Ryou hear banging noises.
Rthe vehicle starts to shake.
Ryou see smoke and smell rubber.
RESP® is intervening constantly.
Rthere are tears in the sidewalls of the tire.
After driving in emergency mode, have the wheel rims checked at a qualified specialist workshop with regard to their further use. The defective tire must be replaced in every case.
