Emergency spare wheel
Important safety notes
G
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 mount 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.
When using an emergency spare wheel or
spare wheel of a different size, you must not
exceed the maximum speed of 50 mph
(80 km/h).
Snow chains must not be mounted on
emergency spare wheels. General notes
You should regularly check the pressure of
the emergency spare wheel, particularly prior
to long trips, and correct the pressure as
necessary (Y page 311). The applicable value
4 Use of snow chains is not permitted .Observe the notes in the "Snow chains" section. Emergency spare wheel

is found on the wheel or under "Technical
data" (
Ypage 343).
An emergency spare wheel may also be
mounted against the direction of rotation.
Observe the time restriction on use as well as
the speed limitation specified on the
emergency spare wheel.
Replace the tires after six years at the latest,
regardless of wear. This also applies to the
emergency spare wheel.
i When you are driving with the collapsible
spare wheel mounted, the tire pressure
loss warning system or the tire pressure
monitor cannot function reliably. Only
restart the tire pressure loss warning
system/the tire pressure monitor when the
damaged wheel has been replaced with a
new wheel.
Vehicles with tire pressur emonitor:
after mounting an emergency spare wheel,
the system may still display the tire
pressure of the removed wheel for a few
minutes .The value displayed for the
mounted emergency spare wheel is not the
same as the current tire pressure of the
emergency spare wheel. Removing the emergency spare wheel
Example
The collapsible spare wheel can be found in
the stowage well under the trunk floor. X
Turn retaining screw 0004counter-clockwise
and remove it.
X Remove collapsible spare wheel 0003. AMG vehicles

the trunk.
X Loosen tensioning straps 0003on both sides.
X Unhook retaining spring hooks 0004and 0024
tensioning strap 0003from the bracket.
X Remove the bag with the collapsible spare
wheel.
X Open the bag and remove the collapsible
spare wheel.
Information on the tire-change tool kit can be
found in the "Where will Ifind...?" section
(Y page 291). Stowing the emergency spare wheel
! Only place the collapsible spare wheel in
the vehicle when it is dry. Otherwise,
moisture may get into the vehicle.
Take the following steps to stow a used
collapsible spare wheel. Otherwise, the
collapsible spare wheel will not install in the
trunk in the intended manner. Mercedes-
Ben zrecommends that you have this work
carried out at a qualified specialist workshop.
X Unscrew the valve cap from the valve.
X If possible, unscrew the valve insert from
the valve and release the air. 340

i
Fully deflating the tires can take a few
minutes.
X Screw the valve insert back into the valve.
X Screw the valve cap back on.
X Pull the protective sheet provided with the
spare wheel over the collapsible spare
wheel.
X Stow the collapsible spare wheel in the
emergency spare wheel well under the
trunk.
X Use the retaining screw to pierce the
protective sheet and fasten the collapsible
spare wheel in place.
X AMG vehicles: pull the bag over the
collapsible spare wheel and close it.
X Place the bag with the collapsible spare
wheel in the trunk.
X Hook in the retaining strap carabiners and
lash the collapsible spare wheel to the
bracket. Inflating the collapsible spare wheel
! Inflate the collapsible spare wheel using
the tire inflation compressor before
lowering the vehicle. The wheel rim could
otherwise be damaged.
! Do not operate the tire inflation
compressor for longer than ten minutes at
a time withou tabreak. It may otherwise
overheat.
The tire inflation compressor can be
operated again once it has cooled down. X
Mount the collapsible spare wheel as
described (Y page 330).
The collapsible spare wheel must be
mounted before it is inflated.
X Pull plug 0023out of the housing.
X Take the air hose out of the housing.
X Insert the yellow hose connector of the air
hose into the guide in the housing and push
it into the fixture until the hose connector
engages.
X Remove the cap from the valve on the
collapsible spare wheel.
X Screw union nut 0003on the air hose onto the
valve.
X Make sure the tire inflation compressor's
on/off switch 0021is set to OFF.
X Insert plug 0023into the socket of the
cigarette lighter or int oa12Vpower socket
in your vehicle.
Observe the notes on the cigarette lighter
(Y page 261). Observe the notes on
sockets (Y page 261).
X Turn the SmartKey to position 1in the
ignition lock (Y page 135).
X Press on/offs witch0021on the tire inflation
compressor to ON.
The tire inflatio ncompressor is switched
on. The tire is inflated. The tire pressure is
shown on pressure gauge 0024.
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, press on/offs witch0021toOFF , on
the tire inflatio ncompressor.
The tire inflation compressor is switched
off.
X Turn the SmartKey to position 0in the
ignition lock.
X If the tire pressure is higher than the
specified pressure, press pressure release

Never allow sparks, flames or smoking
materials near gasoline.
Turn off the engine before refueling.
Whenever you are around gasoline, avoid
inhaling fumes and any skin or clothing
contact.
Direct skin contact with fuels and the
inhalation of fuel vapors are damaging to your
health.

Fuel grade
!
Do not use diesel to refuel vehicles with a
gasoline engine. Even small amounts of the
wrong fuel resultind amage to the fuel
system and engine.
! You should only refuel with unleaded
premium-grade gasoline as this avoids
damaging the catalytic converter.
If engine running problem sare apparent,
have the cause checked immediately and
repaired .Excess unburned fuel can
otherwise enter the catalytic converter,
leading to overheating and possibly
causing a fire.
! To ensure the longevity and full
performance of the engine, only premium-
grade unleaded gasoline may be used. If there is no premium-grade unleaded
gasoline available and regular unleaded
gasoline must be used, please observe the
following precautions:
R
only fill the fuel tank to half full with
regular unleaded gasoline and fill the rest
with premium-grade unleaded gasoline
as soo nas possible.
R do not drive at the maximum speed.
R avoid sudden acceleration.
R if the vehicle is carrying a light load, e.g.
two passengers without luggage, do not
allow the engine to rev above 3000 rpm.
R if the vehicle is fully loaded or is being
operated in mountainous terrain, do not
depress the accelerator pedal further
than 0002of the pedal travel.
Only refuel using premium-grade unleaded
gasoline with a minimum octane rating of 91.
Reformulated Gasoline (RFG) and/or
unleaded gasoline with additives can be used.
The concentration of additives in the fuel,
however, must not exceed 10%, e.g.:
R Ethanol
R TAME
R ETBE
R IPA
R TBA
For MTBE, the concentration should not
exceed 15%.
The concentration of methanol in gasoline,
including other additives, must not exceed
3%.
Using mixtures of methanol and ethanol is not
permitted. Gasohol, a mixture of 10% ethanol
and 90% unleaded gasoline, may be used.
All of these mix fuels must fulfill the fuel
requirements, e.g.:
R knock resistance
R boiling point
R vapor pressure
