Possible cause/consequence
Possible solution
Run Flat Indicator
inactive
Run Flat Indicator* is malfunctioning.

Have the Run Flat Indicator* checked by an autho-
rized Mercedes-Benz Center.
Check tires
Then reactivate
Run Flat Indicator
There was a warning message about a
loss in the tire inflation pressure and
the Run Flat Indicator* has not been
reactivated yet.

Make sure that the correct tire inflation pressure is
set for each tire.

Then reactivate the Run Flat Indicator*.
Run Flat Indicator
unavailable
The Run Flat Indicator* has been
switched off due to an error.

Have the Run Flat Indicator* checked by an autho-
rized Mercedes-Benz Center.
Tire pressure
Check tires
The Run Flat Indicator* indicates that
the pressure is too low in one or more
tires.

Carefully bring the vehicle to a halt, avoiding
abrupt steering and braking maneuvers. Observe
the traffic situation around you.

Check and adjust tire inflation pressure as
required (
page 328).

If necessary, change the wheel (
page 420).

Reactivate the Run Flat Indicator* after adjusting
the tire inflation pressure values (
page 330).
Warning!
G
Do not drive with a flat tire. A flat tire affects
the ability to steer or brake the vehicle.
You may lose control of the vehicle. Contin-
ued driving with a flat tire will cause exces-
sive heat build-up and possibly a fire.

420 Practical hintsFlat tire
Preparing the vehicle
Park the vehicle in a safe distance from
moving traffic on a hard, flat surface
when possible.

Turn on the hazard warning flasher
(page 137).

Turn the steering wheel so that the
front wheels are in a straight ahead
position.

Set the parking brake (
page 57).

Move the gear selector lever toP.
Vehicles with SmartKey:

Turn off the engine (
page 58).

Remove the SmartKey from the starter
switch.Vehicles with SmartKey with
KEYLESS-GO*:

Turn off the engine by pressing the
KEYLESS-GO* start/stop button on the
gear selector lever once (
page 58).

Open the driver’s door (this puts the ig-
nition in position0 (
page 36), same
as with the SmartKey removed from
the starter switch). The driver’s door
then can be closed again.

Have any passenger exit the vehicle at
a safe distance from the roadway.
Warning!
G
The dimensions of the spare wheel is differ-
ent from those of the road wheels. As a re-
sult, the vehicle handling characteristics
change when driving with a spare wheel
mounted. Adapt your driving style accord-
ingly.
The spare wheel is for temporary use only.
When driving with spare wheel mounted,
ensure proper tire pressure and do not ex-
ceed a vehicle speed of 50 mph (80 km/h).
Drive to the nearest Mercedes-Benz Center
as soon as possible to have the spare wheel
replaced with a regular road wheel.
Never operate the vehicle with more than
one spare wheel mounted.
Do not switch off the ESP
® when a Minis-
pare wheel is mounted.
iOpen door only when conditions are
safe to do so.

425 Practical hints
Flat tire
Before storing the jack, it should be fully
collapsed, with handle folded in (storage
position) (
page 400).

Store the jack and the other vehicle
tools in the trunk.
MOExtended system*
The MOExtended system allows you to
continue driving your vehicle even if there
is a total loss of pressure in one or more
tires.
You may only use the MOExtended system
in conjunction with the Run Flat Indicator*.
!The maximum distance in emergency
mode depends on the vehicle’s load. It
is 30 miles (50 km) if the vehicle is par-
tially loaded and 18 miles (30 km) if the
vehicle is fully loaded.
The point at which the maximum driv-
ing distance begins in emergency
mode is when the warning message
appears in the multifunction display
indicating that there is a loss of tire
inflation pressure.
Do not exceed the maximum speed of
50 mph (80 km/h). Warning!
G
In emergency mode, your vehicle’s driving
characteristics are diminished in such situa-
tions as:

driving around curves


while braking


while accelerating rapidly
Therefore, your driving style must be adapt-
ed accordingly. Avoid abrupt steering and
driving maneuvers, as well as driving over
obstacles (road curbs, potholes, or off-road
areas). This is especially important if the ve-
hicle is heavily loaded.
The emergency driving distance that can be
achieved greatly depends on the demands
placed on the vehicle. Depending on speed,
load, driving maneuvers, road conditions,
outside temperature, etc., the distance can
be significantly shorter or, if the vehicle is
driven cautiously, somewhat longer.
Do not continue driving in emergency mode
if

you notice knocking sounds


the vehicle starts to shake


smoke develops and you smell rubber


ESP
® is intervening continuously


you notice tears on the tire sidewalls
After driving in emergency mode, you must
have the rims inspected by an authorized
Mercedes-Benz Center to check if they are
suitable for further use. The failed tire must
be replaced in any case.iWhen replacing individual or all tires on
the vehicle, make sure only matching
tires marked with “MOExtended” are
mounted in the size specified for your
vehicle (
page 445).

445 Technical data
Rims and tires
Rims and tires
!
Only use tires which have been tested
and approved for your vehicle by
Mercedes-Benz. Tires approved by
Mercedes-Benz are developed to pro-
vide best possible performance in con-
junction with the driving safety
systems on your vehicle such as ABS or
ESP
®. Tires specially developed for
your vehicle and tested and approved
by Mercedes-Benz can be identified by
finding the following on the tire’s side-
wall:


MO = M
ercedes-Benz O
riginal
equipment tires


MOE = M
ercedes-Benz O
riginal
E
xtended (tires with limited run-flat
characteristics) original equipment
tires
Using tires other than those approved
by Mercedes-Benz may result in dam-
age that is not covered by the
Mercedes-Benz Limited Warranty.
iFor information on driving with
MOExtended tires, see
“MOExtendedsystem*” (
page 332).
!Using tires other than those approved
by Mercedes-Benz can have detrimen-
tal effects, such as

poor handling characteristics


increased noise


increased fuel consumption
Moreover, tires and rims not approved
by Mercedes-Benz may, under load,
exhibit dimensional variations and dif-
ferent tire deformation characteristics
that could cause them to come into
contact with the vehicle body or axle
parts. Damage to the tires or the vehi-
cle may be the result.
iFurther information on tires and rims is
available at any authorized
Mercedes-Benz Center. A placard with
the recommended tire inflation pres-
sures is located on the driver’s door
B-pillar. Some vehicles may have sup-
plemental tire inflation pressure infor-
mation for driving at high speeds
(page 327) or for vehicle loads less
than the maximum loaded vehicle con-
dition (
page 326). If such information
is provided, it can be found on the plac-
ard located on the inside of the fuel fill-
er flap. The tire inflation pressure
should be checked regularly and
should only be adjusted on cold tires.
Follow tire manufacturer’s mainte-
nance recommendation included with
vehicle.

!Please compare the recommended tire
inflation pressure for your vehicle with
the tire inflation pressure on the yellow
label located on the spare wheel rim.
If the tire inflation pressure on the yel-
low label on the spare wheel rim differs
from the values given in this Operator’s
Manual, inflate the spare wheel tire to
the recommended tire inflation pres-
sure given on the yellow label on the
spare wheel rim.
iPlease note that the tire inflation pres-
sure of the Minispare tire differs from
the tire inflation pressure of the road
tires.
Make sure the Minispare tire is inflated
to approximately 60 psi (4.1 bar).
