Starting the combustion engineEnclosed areas
Do not let the engine run in enclosed
areas; otherwise, breathing of 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 dan‐
ger.
Before leaving the vehicle with the engine run‐
ning, set the parking brake and place the trans‐
mission in 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 catalytic
converter.◀
The combustion engine is started with Activate
drive, refer to page 64, readiness under the fol‐
lowing conditions:▷The drive system is not at operating tem‐
perature.▷The temperature of the hybrid system is too
high.▷The high-voltage battery has an insufficient
charge.
Driving away
1.Activate drive readiness.2.Select transmission position D, M/S or R.3.Release the parking brake.4.Drive away.Deactivating drive readiness
After parking the vehicle, you may hear noises
due to operation of the hybrid system, such as
for cooling of the high-voltage battery.
After stopping the vehicle:1.Select transmission position P.2.Press the Start/Stop button.3.Set the parking brake.
Before driving into a car wash
In order for the vehicle to be able to roll into a car
wash, heed the information regarding Washing
in automatic car washes, refer to page 200.
Auto Start/Stop function
The concept
The Auto Start/Stop function helps save fuel.
The system switches off the combustion engine
when conditions for electric driving, refer to
page 66, have been met. The ignition remains
switched on.
READY appears on the tachometer. If neces‐
sary, the combustion engine starts automati‐
cally.
The combustion engine is also stopped during
the trip when braking or coasting. This driving
condition, in which the vehicle is traveling with‐
out power and energy recovery is not active, is
referred to as coasting, refer to page 66.
Note
The combustion engine is not switched off au‐
tomatically in the following situations:
▷The combustion engine is not yet at oper‐
ating temperature.▷The transmission selector lever is in position
M/S.▷The high-voltage battery charge is very low
or there is a high load on the vehicle electri‐Seite 65DrivingControls65

Socket for OBD Onboard
Diagnosis
Position
There is an OBD socket on the driver's side for
checking the primary components in the vehicle
emissions.
Emissions
▷The warning lamp lights up:
Emissions are deteriorating. Have
the vehicle checked as soon as pos‐
sible.
Canadian model: warning light indi‐
cates the engine symbol.▷The warning lamp flashes under certain cir‐
cumstances:
This indicates that there is excessive misfir‐
ing in the engine.
Reduce the vehicle speed and have the sys‐
tem checked immediately; otherwise, seri‐
ous engine misfiring within a brief period can
seriously damage emission control compo‐
nents, in particular the catalytic converter.
Fuel cap
The indicator lamp lights up.
If the fuel cap is not properly tightened,
the OBD system may conclude that fuel
vapor is escaping. If the cap is then tightened,
the display should go out in a short time.
