2015 MERCEDES-BENZ SLK-CLASS ROADSTER fuel consumption

the values in theFrom Resetsubmenu are
calculated from the last time the submenu
was reset ( Ypage 198).
The
From Starttrip computer is automati-
cally reset when:
R the ignition has been switched off for more
than four hours.
R 999 hours have been exceeded.
R 9,999 miles have been exceeded.
The
From Resettrip computer is automati-
cally reset if the value exceeds 9,999 hours or 99,999 miles.
ECO display
Example: ECO display
X Press the =or; button on the steer-
ing wheel to select the
Tripmenu.
X Press the 9or: button to select
ECO DISPLAY.
If the ignition remains switched off for longer than four hours, the ECO display will be auto-
matically reset.
For further information on the ECO display,
see ( Ypage 165).
Displaying the range and current fuel
consumption
For AMG vehicles, only the approximate
range will be displayed. X
Press the =or; button on the steer-
ing wheel to select the
Tripmenu.
X Press the 9or: button to select the
current fuel consumption and approximate range.
The approximate range that can be covered
depends on the fuel level and your current
driving style. If there is only a small amount of
fuel left in the fuel tank, the display shows a
vehicle being refueled Cinstead of the
range.
Digital speedometer
X Press the =or; button on the steer-
ing wheel to select the
Tripmenu.
X Press the 9or: button to select
digital speedometer ;.
A gearshift recommendation :Zmay also
be displayed.
Observe the information on gearshift rec-
ommendation :for manual transmission
( Y page 151) or when shifting manually
(automatic transmission) ( Ypage 154).
AMG vehicles: a gearshift recommendation
appears in the status area of the multifunc-
tion display and not in the display of the
digital speedometer.

pressure to the value specified for cold tires.The tire pressure would otherwise be too low.
Observe the recommended tire pressures for
cold tires:
R on the Tire and Loading Information placard
on the B-pillar on the driver's side
R in the tire pressure table on the inside of the
fuel filler flap
R printed in yellow on the rim of the emer-
gency/collapsible spare wheel (depending
on vehicle equipment)
Underinflated or overinflated tires
Underinflation
GWARNING
Tires with pressure that is too low can over-
heat and burst as a consequence. In addition, they also suffer from excessive and/or irreg-
ular wear, which can severely impair the brak-ing properties and the driving characteristics.There is a risk of an accident.
Avoid tire pressures that are too low in all the
tires, including the spare wheel.
Underinflated tires may:
R overheat, leading to tire defects
R have an adverse effect on handling charac-
teristics
R wear quickly and unevenly
R have an adverse effect on fuel consumption
Overinflation
GWARNING
Tires with excessively high pressure can burst
because they are damaged more easily by
road debris, potholes etc. In addition, they
also suffer from irregular wear, which can
severely impair the braking properties and the
driving characteristics. There is a risk of an
accident.
Avoid tire pressures that are too high in all the
tires, including the spare wheel. Overinflated tires may:
R increase the braking distance
R have an adverse effect on handling charac-
teristics
R wear quickly and unevenly
R have an adverse effect on ride comfort
R be more susceptible to damage
Maximum tire pressures
:Example: maximum permissible tire pres-
sure
Never exceed the maximum permissible tire
inflation pressure. Always observe the rec-
ommended tire pressure for your vehicle
when adjusting the tire pressure( Y page 315).
iThe actual values for tires are vehicle-
specific and may deviate from the values in
the illustration.
Checking the tire pressures
Important safety notes
Observe the notes on tire pressure ( Y page 315).
Information on air pressure for the tires on
your vehicle can be found:
R on the vehicle's Tire and Loading Informa-
tion placard on the B-pillar
R on the tire pressure label on the fuel fillerflap
R in the "Tire pressure" section
318Tire pressure
Wheels and tires

XAMG vehicles and vehicles with AMG
equipment: insert the cover into the outer
sill.
X Check the tire pressure of the newly moun-
ted wheel and adjust it if necessary.
Observe the recommended tire pressure ( Y page 315).
iWhen 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 sys-
tem/the tire pressure monitor when the
damaged wheel has been replaced with a
new wheel.
Vehicles with a tire pressure control
system: all installed wheels must be equip-
ped with functioning sensors.
Wheel and tire combinations
General notes
!
For safety reasons, Mercedes-Benz rec-
ommends that you only use tires and
wheels which have been approved by
Mercedes-Benz specifically for your vehi-
cle.
These tires have been specially adapted for use with the control systems, such as ABS
or ESP ®
, and are marked as follows:
R MO = Mercedes-Benz Original
R MOE = Mercedes-Benz Original Extended
(tires featuring run-flat characteristics)
R MO1 = Mercedes-Benz Original (only cer-
tain AMG tires)
Mercedes-Benz Original Extended tires
may only be used on wheels that have been
specifically approved by Mercedes-Benz.
Only use tires, wheels or accessories tes-
ted and approved by Mercedes-Benz. Cer-
tain characteristics, e.g. handling, vehicle
noise emissions or fuel consumption, may
otherwise be adversely affected. In addi-
tion, when driving with a load, tire dimen- sion variations could cause the tires to
come into contact with the bodywork and
axle components. This could result in dam-
age to the tires or the vehicle.
Mercedes-Benz accepts no liability for
damage resulting from the use of tires,
wheels or accessories other than those tes-
ted and approved.
Information on tires, wheels and approved
combinations can be obtained from any
qualified specialist workshop.
!Retreaded tires are neither tested nor rec-
ommended by Mercedes-Benz, since pre-
vious damage cannot always be detected
on retreaded tires. As a result, Mercedes-
Benz cannot guarantee vehicle safety if
retreaded tires are mounted. Do not mount used tires if you have no information about
their previous usage.
Overview of abbreviations used in the follow-
ing tire tables: R BA: both axles
R FA: front axle
R RA: rear axle
The recommended pressures for various
operating conditions can be found:
R on the Tire and Loading Information placard
with the recommended tire pressures on
the B-pillar on the driver's side
R in the tire pressure table on the inside of the
fuel filler flap
Observe the notes on recommended tire
pressures under various operating conditions ( Y page 315).
Check tire pressures regularly, and only when the tires are cold. Comply with the mainte-
nance recommendations of the tire manufac-
turer in the vehicle document wallet.
Notes on the vehicle equipment – always
equip the vehicle with:
R tires of the same size on a given axle (left/
right)
R the same type of tires at a given time (sum-
mer tires, winter tires, MOExtended tires)
