Mercedes-Benz GL-Class: Starting the engine
Important safety notes
WARNING
Inhalation of exhaust gas is hazardous to your
health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause
unconsciousness and possible death.
Do not run the engine in confined areas (such
as a garage) which are not properly ventilated.
If you think that exhaust gas fumes are
entering the vehicle while driving, have the
cause determined and corrected
immediately. If you must drive under these
conditions, drive only with at least one
window fully open at all times.
Do not depress the accelerator pedal
when starting the engine.
Vehicles with a gasoline engine: the
catalytic converter is preheated for up to
30 seconds after a cold start. During this
time, the engine sound may be different.
Automatic transmission
► Shift the transmission to position P.
The transmission position display in the multifunction display shows P.
You can also start the engine when the
transmission is in position 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.
► To start a gasoline engine: turn the SmartKey to position 3 in the ignition lock and release it as soon as the engine is running.

not leave children unattended in the vehicle,

result in an accident and/or serious personal
injury.
The Start/Stop button can be used to
start the vehicle without inserting the
