Drive sensibly–save fuel
Observe the following tips to save fuel:
RThe tires should always be inflated to the
recommended tire pressure.
RRemove unnecessary loads.
RRemove roof racks whenthey are not
needed.
RWarm up the engine at low engine speeds.
RAvoid frequent acceleration or braking.
RHave all maintenance work carried out as
indicated by the service intervals in the
Maintenance Booklet or by the service
interval display.
Fuel consumption also increases when
driving in cold weather, in stop-start traffic
and in hilly terrain.
Drinking and driving
GWARNING
Drinking and driving and/or taking drugs and
driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and
judgment.
The possibility of a serious or even fatal
accident is greatly increased when you drink
or take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or
taking drugs.
Emission control
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces
without sufficient ventilation.
Certain engine systems are designed to keep
the level of poisonous components in exhaust
fumes within legal limits.
These systems only work at peak efficiency if
they are serviced exactly in accordance with
the manufacturer's specifications. For this
reason, only have work on the engine carried
out by qualified and authorized Mercedes-
Benz technicians.
The engine settings must not be changed
under any circumstances. Furthermore, all
specific service work must be carried out at
regular intervals and in accordance with the
Mercedes-Benzservice requirements. Details
can be found in the Maintenance Booklet.
ECO display
The ECO display gives you information on how
economical your driving style is. The ECO
display assists you in achieving the optimum
driving style in terms of consumption, taking
the actual and selected conditions into
consideration.Your driving style can
significantly influence the vehicle's
consumption.
Example: ECO display
The ECO display consists of three bars:
RAcceleration
RConstant
RCoasting
The percent value is the average value of the
three bars. The three bars and the mean value
begin at the value of 50%.Ahigher
percentage indicates a moreeconomical
driving style.
The ECO display does not indicate the actual
fuel consumption and a fixed percentage
count in the ECO display does not indicate a
fixed consumption figure.

Check
Tire Pressure Soon
Canada only:
The tire pressure loss warningsystem has detected a significant
loss in pressure.
Awarning tone also sounds.
GWARNING
With tire pressures which are too low, there is a riskofthe
following hazards:
Rthey may burst, especially as the load and vehicle speed
increase.
Rthey may wear excessively and/or unevenly, which may greatly
impair tire traction.
Rthe driving characteristics, as well as steering and braking, may
be greatly impaired.
There is a risk of an accident.
XStop the vehicle without making any sudden steering or braking
maneuvers. Pay attention to the traffic conditions as you do so.
XSecure the vehicle against rolling away (Ypage 153).
XCheck the tires and, if necessary, follow the instructions for a
flat tire (Ypage 295).
XCheck the tire pressures and, if necessary, correct the tire
pressure.
XRestart the tire pressure loss warning system when the tire
pressure is correct (Ypage 319).
CheckTirePressure
Then Restart Run
Flat Indicator
Canada only:
The tire pressure loss warning system generated a display
message and has not been restarted since.
XSet the correct tire pressure in all four tires.
XRestart the tire pressure loss warning system (Ypage 319).

Inoperative
Canada only:
The tire pressure loss warning system is faulty.
XVisit a qualified specialist workshop.
Correct Tire
Pressure
The tire pressure is too low in at least one of the tires, or the tire
pressure difference between the wheels is too great.
XCheck the tire pressures at the next opportunity (Ypage 320).
XIf necessary, correct the tire pressure.
XRestart the tire pressure monitor (Ypage 322).

If you drive with a flat tire, there is a risk of the following hazards:
Ra flat tire affects the ability to steer or brake the vehicle.
RYou could lose control of the vehicle.
Rcontinued driving with a flat tire will cause excessive heat build-
up and possibly a fire.
There is a risk of an accident.

Manual. Country-specific differences are
possible. Please note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.

Vehicle tool kit
General notes
Vehicles with a TIREFIT kit: the TIREFIT kit is
located in the stowage well under the trunk
floor.
Vehicles with a tire-changetool kit: the tire-
change tool kit is in the stowage well under
the trunk floor.
iApart from certain country-specific
variations, the vehicles are not equipped
with a tire-change tool kit. Some tools for
changing a wheel are specific to the
vehicle. For more information on which
tools are required and approved to perform
a wheel change on your vehicle, consult a
qualified specialist workshop.
Tools required for changingawheel may
include, for example:
RJack
RWheel chock
RLug wrench

Preparing the vehicle
Your vehicle may be equipped with:
RMOExtended tires (tires with run-flat
properties) (Ypage 295)
Vehicle preparation is not necessary on
vehicles with MOExtended tires.
Ra TIREFIT kit (Ypage 294)
Information on changing/mounting a wheel
(Ypage 336).
XStop the vehicle on solid, non-slippery and
level ground, as far away as possible from
traffic.
XSwitch on the hazard warning lamps.
XSecure the vehicle against rolling away
(Ypage 153).
XIf possible, bring the frontwheels into the
straight-ahead position.
XSwitch off the engine.
XRemove the SmartKey from the ignition
lock.
XAll occupants must get out of the vehicle.
Make sure that they are not endangered as
they do so.
XMake 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.
XGet out of the vehicle. Pay attention to
traffic conditions when doing so.
XClose the driver's door.
iVehicles equipped with MOExtended tires
are not equipped with a TIREFIT kit at the
factory. It is therefore recommended that
you additionally equip your vehicle with a
TIREFIT kit if you mount tires that do not
feature run-flat properties, e.g. winter tires.
A TIREFIT kit can be obtained from a
qualified specialist workshop.
MOExtended tires (tires with run-flat
properties)
General notes
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. The affected
tire must not show any clearly visible damage.
You can recognize MOExtended tires by the
MOExtended marking which appears on the
sidewall of the tire. You will find this marking
next to the tire size designation, the load-
bearing capacity and the speed index
(Ypage 330).
MOExtended tires may only be used in
conjunction with an active tire pressure loss
warning system or with an active tire pressure
monitor.
If the pressure loss warning message
appears in the multifunction display:
RObserve the instructions in the display
messages (Ypage 234).
RCheck the tire for damage.
RIf driving on, observe the following notes.
The maximum driving distance is
approximately 50 miles (80 km) when the
vehicle is partially laden and approximately
18 miles (30 km) when the vehicle is fully
laden.
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
