In addition to driving style, the actual consump-
tion is affected by other factors, such as: R
Load R
Tire pressure R
Cold start R
Choice of route R
Active electrical consumers
These factors are not include dint he ECO dis-
play.
An economical driving style specially requires
driving at moderate engine speeds.
Achieving ah igher valu eint he categories
"Acceleration" and "Constant": R
observe the gearshift recommendations. R
drive the vehicle in drive program C or E
(vehicles with aD YNAMIC SELECT button).
On long journeys at ac onstant speed ,e .g. on the
highway, only the outer area for "constant" will
change.
The ECO display summarizes the driving style
from the start of the journey to its completion.
Therefore, there are more marked changes in
the outer area satt he start of aj ourney. On lon-
ger journeys, there are fewer changes. For more
marked changes, perform am anua lr est
( Y
page 181).
For more information on the ECO display, see
( Y
page 180).
Braking
Important safety notes
G WARNING
If you shift down on as lippery road surface in
an attempt to increase the engine's braking
effect, the drive wheel sc ould lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on as lippery road surface.
Downhill gradients
! On long and steep gradients, you must
reduce the load on the brakes by shifting to a
lowe rg ear in good time. This allows you to
take advantage of engine braking. For this you
must first activate manua lg earshifting. This helps you to avoid overheating the brakes and
wearing them out excessively.
When you take advantage of engine braking, it
is possible that ad rive wheel wil ln ot rotate for
some time, e.g. on as lippery road surface.
This could cause damage to the drive train.
This type of damage is not covered by the
Mercedes-Benz warranty.
Briefly depressing the accelerator peda lo n
downhill gradients whil et he manua ld rive pro-
gram M is temporaril ya ctivated: the automatic
transmission may switch to the last active auto-
matic drive program E or S .T he automatic trans-
missio nm ay shift to ah ighe rg ear. This can
reduce the engine's braking effect.
Heavy and light loads
G WARNING
If you rest you rf oot on the brake peda lw hile
driving, the braking system can overheat. This
increases the stopping distance and can even
cause the braking system to fail .T here is a
risk of an accident.
Never use the brake peda lasaf ootrest. Never
depres st he brake peda la nd the accelerator
peda latt he same time.
! Depressing the brake peda lc onstantly
results in excessive and premature wea rt o
the brake pads.
If the brakes have been subjected to ah eavy
load ,don ot stop the vehicle immediately .D rive
on for as hort while. This allows the airflow to
cool the brakes more quickly.
Wet roads If you have driven for al ong time in heavy rain
withou tb raking, there may be ad elayed reac-
tion from the brakes when braking for the first
time. This may also occur after the vehicle has
been washed or driven through deep water.
You have to depres st he brake peda lm ore
firmly .M aintai nag reater distance from the
vehicle in front.
After driving on aw et road or having the vehicle
washed, brake firmly whil ep aying attention to
the traffic conditions. This wil lw arm up the
brake discs, thereby drying them more quickly
and protecting them against corrosion.146

system (Canad ao nly) or tire pressure monitor
(USA only).
If ap ressure loss warning message appears
in the multifunction display: R
observe the instructions in the displa ym es-
sages ( Y
page 211).R
check the tire for damage R
if driving on, observe the following notes
The driving distance possible in run-flat mode is
approximately 50 miles (80 km) when the vehi-
cle is partiall yl aden. When the vehicle is fully
laden it is approximately 19 miles (30 km).
In addition to the vehicle load, the driving dis-
tance possible depends upon: R
vehicle speed R
road condition R
outside temperature
The driving distance possible in run-flat mode
may be reduced by extreme driving conditions
or maneuvers, or it can be increased through a
moderate style of driving.
The driving distance possible in run-flat mode is
counted from the moment the tire pressure loss
warning appears in the multifunction display.
You must not exceed am aximum speed of
50 mph (80 km/h).
When replacing one or all tires, please observe
the following specifications for your vehicle's
tires: R
size R
type and R
the "MOExtended" marking
If at ire has gone flat and cannot be replaced
with aM OExtended tire, as tandard tire may be
used as at emporary measure. Make sure that
you use the proper size and type (summer or
winter tire).
Vehicles equipped with MOExtended tires are
not equipped with aT IREFIT kit at the factory. It
is therefore recommended that you additionally
equip your vehicle with aT IREFIT kit if you mount
tires that do not feature run-flat properties, e.g.
winter tires. AT IREFIT kit may be obtained from
aq ualified specialist workshop.
Important safety notes
G WARNING
When driving in emergency mode, the driving
characteristics deteriorate, e.g. when corner- ing, accelerating quickly and when braking.
There is ar isk 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 al aden
vehicle.
Stop driving in emergency mode if: R
you hear banging noises. R
the vehicle starts to shake. R
you see smoke and smell rubber. R
ESP ®
is intervenin gc onstantly.R
there are tears in the sidewalls of the tire.
After driving in emergency mode, have the
wheel rims checked at aq ualified specialist
workshop with regard to their further use. The
defective tire must be replaced in every case.
TIREFIT kit
Important safety notes TIREFIT is at ire sealant.
Only valid for USA: You can use TIREFIT to seal
punctures of up to 0.16 in (4 mm), particularly
those in the tire tread. You can use TIREFIT at
