Starting the engine
Hints Enclosed areas
Do not let the engine run in enclosed
areas, since breathing in exhaust fumes may
lead to loss of consciousness and death. The
exhaust gases contain carbon monoxide, an
odorless and colorless, but highly toxic gas.◀
Unattended vehicle
Do not leave the vehicle unattended with
the engine running; doing so poses a risk of
danger.
Before leaving the vehicle with the engine run‐
ning, set the parking brake and place the trans‐
mission in selector lever position P or neutral
to prevent the vehicle from moving.◀
Repeated starting in quick succession
Avoid repeated unsuccessful attempts to
start the vehicle or starting the vehicle several
times in quick succession. Otherwise, the fuel
is not burned or is inadequately burned, posing
a risk of overheating and damage to the cata‐
lytic converter.◀
Do not wait for the engine to warm-up while
the vehicle remains stationary. Start driving at
moderate engine speeds.
Diesel engine
If the engine is cold and temperatures are be‐
low approx. 32 ℉/0 ℃, the start process may
be delayed somewhat due to automatic pre‐
heating.

Coasting
The concept The system helps to conserve fuel.
To do this, under certain conditions the engine
is automatically decoupled from the transmis‐
sion when selector lever position D is engaged.
The vehicle continues traveling with the engine
idling to reduce fuel consumption. Selector
lever position D remains engaged.
This driving condition is referred to as coast‐
ing.
As soon as the brake or accelerator pedal is depressed, the engine is automatically coupled
to the transmission again.
Hints
Coasting is a component of the ECO PRO, re‐
fer to page 194, driving mode.
Coasting is automatically activated when ECO
PRO mode is called via the Driving Dynamics
Control.
The function is available in a certain speed
range.
A forward-looking driving style helps the driver
to use the function as often as possible and
supports the fuel-conserving effect of coast‐
ing.
Safety mode
The function is not available if one of the fol‐
lowing conditions is satisfied.▷DSC OFF or TRACTION activated.▷Driving in the dynamic limit range and on
steep uphill or downhill grades.▷Battery charge status temporarily too low
or vehicle electrical system drawing exces‐
sive current.▷Cruise control activated.
