WARNING
The wheel or tire size as well as the tire type
of the spare wheel or emergency spare wheel
and the wheel to be replaced may differ.
Mounting an emergency spare wheel may
severely impair the driving characteristics.
There is a risk of an accident. To avoid hazardous situations:
R
adapt you rdriving style accordingly and
drive carefully.
R never install more than one spare wheel or
emergency spare wheel that differs in size.
R only use a spare wheel or emergency spare
wheel of a different size briefly.
R do not switch ESP ®
off.
R have 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 withou taspare 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

1(Y page 131) in the ignition lock.
X Press on/off switch 0020on the tire inflation
compressor to ON.
The tire inflation compressor is switched
on. The tire is inflated. The tire pressure is
read at pressure gauge 0023.
! Do not operate the tire inflation
compressor for longer than ten minutes at
a time without a break. It may otherwise
overheat.
The tire inflation compressor can be
operated again once it has cooled down. X
Inflate the tire to the specified tire
pressure.
The specified tire pressure is printed on the
yellow label of the emergency spare wheel.
X When the specified tire pressure has been
reached, switch on/off switch 0020on the
tire inflation compressor to OFF.
The tire inflation compressor is switched
off.
X Turn the SmartKey to position 0in the

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.
! Inflate the collapsible spare wheel using
the tire inflation compressor before
lowering the vehicle. The wheel rim could
otherwise be damaged.
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. 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.
X Tighten the wheel bolts evenly in a
crosswise pattern in the sequence
indicated ( 0002to0020). The tightening torque
must be 96 lb-ft (130 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.
X Vehicles with AMG equipment: insert the
cover into the outer sill.
X Place the damaged wheel in the protective
covering (if available) from the tire-change
tool kit, and stow it in the trunk.
The roof must be closed when doing so.
i USA only: 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.
MOExtended tires may only be used in
conjunction with the activated tire pressure
loss warning system or with the activated tire
pressure monitoring system.
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:
R speed
R road condition
R outside 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. Flat tire

Important safety notes
G
WARNING
If you tow the vehicle, you must use a rigid
towing ba rif:
R the engine is not running.
R there is a brake system malfunction.
R there is a malfunction in the power supply
or the vehicle's electrical system.
The power assistance for the steering and the
brake force booster do not work when the
engine is not running. You will need more
force to steer and brake, you may have to
depress the brake pedal with maximu mforce.
Before towing away, make sure that the
steering can be moved and is not locked.
If you tow or tow-start another vehicle, its
weight must not exceed the maximum
permissible gross vehicle weight of your
vehicle.
It is better to have the vehicle transported
than to have it towed.
! The vehicle can be towed a maximum of
30 miles (50km). The towing speed of
30 mph (50 km/h) must not be exceeded.
If the vehicle has to be towed more than
30 miles (50km), the entire vehicle must be
raised and transported.
! Make sure that the electric parking brake
is released. If the electric parking brake is
faulty, visit a qualified specialist workshop.
! Only secure the tow rope or tow bar at the
towing eyes. Otherwise, the vehicle could
be damaged.
! Do not use the towing eye for recovery,
as this could damage the vehicle. If in
doubt, recover the vehicle with a crane.
! Drive slowly and smoothly when towing.
Excessive tractive power could otherwise
damage the vehicles. !
Do not tow with sling-type equipment.
This could damage the vehicle.
! On vehicles with KEYLESS-GO, use the
SmartKey instead of the Start/Stop
button. Turn the SmartKey to position 2in
the ignition lock and shift the automatic
transmission to N. Then, turn the SmartKey
back to 0and leave it in the ignition lock.
When towing a vehicle with an automatic
transmission, the transmission must be in
position N.
The battery must be connected and charged.
Otherwise, you:
R cannot turn the SmartKey to position 2in
the ignition lock
R cannot shift the transmission to position
N on vehicles with automatic transmission
Vehicles with automatic transmission:
