Starting the engine
General information Enclosed 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.◀
Frequent starting in quick succession
Avoid repeated futile attempts at starting
the car and avoid starting the car frequently in
quick succession. Otherwise, the fuel is not
burned or is inadequately burned, and there is
the danger of overheating and damaging the
catalytic converter.◀
Do not wait for the engine to warm up while the
vehicle remains stationary. Start driving at mod‐
erate engine speeds.

In this way braking efficiency will be available
when you need it.
Hills
Drive long or steep downhill gradients in the gear
in which the least braking is required. Otherwise,
the brake system may overheat, resulting in a
reduction in the brake system efficiency.
Automatic transmission:
You can increase the engine's braking effect by
shifting down in the manual mode of the auto‐
matic transmission.
Avoid load on the brakes
Avoid placing excessive load on the brake
system. Light but consistent brake pressure can
lead to high temperatures, brake wear and pos‐
sibly 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 is unavailable
with the engine stopped.◀
Brake disc corrosion
Corrosion on the brake discs and contamination
on the brake pads are furthered by:▷Low mileage.▷Extended periods when the vehicle is not
used at all.▷Infrequent use of the brakes.
Corrosion occurs when the minimum pressure
that must be exerted by the pads during brake
applications to clean the discs is not reached.
Should corrosion form on the brake discs, the
brakes will tend to respond with a pulsating ef‐
fect that generally cannot be corrected.
Condensation under the parked vehicle
When using the automatic climate control, con‐
densation water develops that exits underneath
the vehicle.
Therefore, traces of condensed water under the
vehicle are normal.Seite 158Driving tipsThings to remember when driving158
