▷When the vehicle is locked using the cen‐
tral locking system.▷Shortly before the battery is discharged
completely, so that the engine can still be
started.
The radio-ready state remains active if, e.g.,
the ignition is automatically switched off for the
following reasons:
▷Opening or closing the driver's door.▷Unfastening of the driver's safety belt.▷When automatically switching from low
beams to parking lights.
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 N to pre‐
vent the vehicle from moving.◀
Repeated starting in quick succession
Avoid trying to start the vehicle repeat‐
edly and in quick succession. Otherwise, the fuel is not burned or is inadequately burned,
posing a risk of overheating and damage to the
catalytic converter.◀
Do not wait for the engine to warm-up while
the vehicle remains stationary. Start driving at
moderate engine speeds.
Steptronic transmission
Starting the engine1.Depress the brake pedal.2.Press the Start/Stop button.
The ignition is activated automatically for a
certain time and is stopped as soon as the en‐
gine starts.
Engine stop
Hints Take the remote control with you
Take the remote control with you when
leaving the vehicle so that children, e.g., can‐
not start the engine.◀
Apply parking brake and further secure
the vehicle if needed.
Set the parking brake firmly when parking; oth‐
erwise, the vehicle could roll. On steep upward
and downward inclines, further secure the ve‐
hicle, e.g., by turning the steering wheel in the
direction of the curb.◀
Before driving into a car wash
So that the vehicle can roll into a car wash ob‐
serve instructions for going into an automatic
car wash, refer to page 228.
Steptronic transmission
Switching off the engine
1.Engage selector lever position P with the
vehicle stopped.2.Press the Start/Stop button.
The engine is switched off.
The radio-ready state is switched on.3.Set the parking brake.Seite 69DrivingControls69

Objects within the range of movement
of the pedals
No objects in the area around the pedals
Keep floor mats, carpets, and any other
objects out of the pedal area; otherwise, the
function of the pedals could be impeded while
driving and create the risk of an accident.
Do not place additional floor mats over existing
mats or other objects.
Only use floor mats that have been approved
for the vehicle and can be properly attached to
floor.
Ensure that the floor mats are securely fas‐
tened again after they were removed for clean‐
ing, e.g.◀
Driving in wet conditions When roads are wet, salted, or in heavy rain,
press brake pedal ever so gently every few
miles.
Ensure that this action does not endanger other traffic.
The heat generated in this process helps dry
the brake discs and pads.
In this way braking efficiency will be available
when you need it.
Hills Avoid stressing the brakes
Avoid placing excessive stress on the
brake system. Light but consistent brake pres‐
sure can lead to high temperatures, brakes
wearing out and possibly even brake failure.◀
Do not drive in neutral
Do not drive in neutral or with the engine
stopped, as doing so disables engine braking.
In addition, steering and brake assist are un‐
available with the engine stopped.◀
Drive long or steep downhill gradients in the
gear that requires least braking efforts. Other‐wise the brakes may overheat and reduce
brake efficiency.
You can increase the engine's braking effect
by shifting down, going all the way to first gear,
if needed.
Brake disc corrosion
Brake disc corrosion and contamination of the
brake pads are favored by:▷Low mileage.▷Extended periods when the vehicle is not
used at all.▷Infrequent use of the brakes.
Corrosion will built up when the maximum
pressure applied to the brake pads during
braking is not reached - thus discs don't get
cleaned.
Corrosion buildup on the brake discs will cause
a pulsating effect on the brakes in their re‐
sponse - generally that cannot be corrected.
Condensation under the parked
vehicle
When using the automatic climate control,
condensation water develops collecting under‐
neath the vehicle.
These traces of water under the vehicle are
normal.
