2016 MERCEDES-BENZ SLK-Class keyless

iMercedes-AMG vehicles:the exhaust
flap of the exhaust system is checked after
each cold start. A resulting noise can be
heard during this process.
iDuring a cold start, the engine runs at
higher speeds to enable the catalytic con-
verter to reach its operating temperature.
The sound of the engine may change during
this time.
Automatic transmission
XShift the transmission to position P.
The transmission position display in the
multifunction display shows P.
iYou can start the engine in transmission
position Pand N.
Starting procedure with the SmartKey
To start the engine using the SmartKey
instead of KEYLESS-GO, pull the Start/Stop
button out of the ignition lock.
XTurn the SmartKey to position 3in the igni-
tion lock and release it as soon as the
engine is running (
Ypage 139).
Using KEYLESS-GO to start the engine
The Start/Stop button can be used to start
the vehicle manually without inserting the
SmartKey into the ignition lock. The Start/
Stop button must be inserted in the ignition
lock and the SmartKey must be in the vehicle.
This mode for starting the engine operates
independently of the ECO start/stop auto-
matic engine start function.
XDepress the brake pedal and keep it
depressed.
XPress the Start/Stop button once
(
Ypage 140).
The engine starts.
Pulling away
General notes
GWARNING
If the engine speed is above the idling speed
and you engage transmission position Dor R,
the vehicle could pull away suddenly. There is
a risk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do not simultaneously accelerate.
!Change gear in good time and avoid spin-
ning the wheels. You could otherwise dam-
age the vehicle.
Depress the accelerator carefully when pull-
ing away.
The vehicle locks centrally once you have
pulled away. The locking knobs in the doors
drop down.
You can open the doors from the inside at any
time.
You can also deactivate the automatic locking
feature (
Ypage 206).
It is only possible to shift the transmission
from position Pto the desired position if you
depress the brake pedal. Only then is the shift
lock released.
iUpshifts take place at higher engine
speeds after a cold start. This helps the
catalytic converter to reach its operating
temperature more quickly.
Information on the automatic release of the
electric parking brake (
Ypage 161).
Hill start assist
Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient. It
holds the vehicle for a short time after you
have removed your foot from the brake pedal.
This gives you enough time to move your foot
from the brake pedal to the accelerator pedal
and to depress it before the vehicle begins to
roll.

Refueling
Important safety notes
GWARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is a risk of fire and explo-
sion.
You must avoid fire, open flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating before refueling.
GWARNING
Fuel is poisonous and hazardous to health.
There is a risk of injury.
You must make sure that fuel does not come into contact with your skin, eyes or clothing
and that it is not swallowed. Do not inhale fuel
vapors. Keep fuel away from children.
If you or others come into contact with fuel,
observe the following:
RWash away fuel from skin immediately
using soap and water.
RIf fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance with-
out delay.
RIf fuel is swallowed, seek medical assis-
tance without delay. Do not induce vomit-
ing.
RImmediately change out of clothing which
has come into contact with fuel.
GWARNING
Electrostatic buildup can create sparks and
ignite fuel vapors. There is a risk of fire and
explosion.
Always touch the vehicle body before opening
the fuel filler flap or touching the fuel pump
nozzle. Any existing electrostatic buildup is
thereby discharged.
Do not get into the vehicle again during the
refueling process. Otherwise, electrostatic
charge could build up again.
!Do not use diesel to refuel vehicles with a
gasoline engine. Do not switch on the igni-
tion if you accidentally refuel with the
wrong fuel. Otherwise, the fuel will enter
the fuel system. Even small amounts of the wrong fuel could result in damage to the
fuel system and the engine. Notify a quali-
fied specialist workshop and have the fuel
tank and fuel lines drained completely.
!Overfilling the fuel tank could damage the
fuel system.
!Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
!Use a filter when refueling from a fuel can.
Otherwise, the fuel lines and/or injection
system could be blocked by particles from
the fuel can.
If you overfill the fuel tank, fuel could spray
out when the fuel pump nozzle is removed.

Preparing the vehicle
Your vehicle may be equipped with:
Rtires with run-flat characteristics
(MOExtended tires) (
Ypage 291)
Vehicle preparation is not necessary on
vehicles with MOExtended tires
Ran emergency spare wheel (Ypage 339)
Vehicles equipped with MOExtended tires are
not equipped with a TIREFIT kit at the factory.
It is therefore recommended that you addi-
tionally 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 may
be obtained from a qualified specialist work-
shop.

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 324).
MOExtended tires may only be used in con-
junction with an active tire pressure loss
warning system or with an active tire pressure
monitor.
If a pressure loss warning message
appears in the multifunction display:
Robserve the instructions in the display mes-
sages (
Ypage 234).
Rcheck the tire for damage.
Rif driving on, observe the following notes.
The driving distance possible in run-flat mode
is approximately 50 miles (80 km) when the
vehicle is partially laden and approximately
18 miles (30 km) when the vehicle is fully
laden.
