Mirrors
Exterior mirrors
General information The mirror on the passenger side is more
curved than the driver's side mirror.
Depending on the vehicle equipment, the mir‐
ror setting is stored for the profile currently in
use. When the vehicle is unlocked via the re‐
mote control, the position is automatically re‐
trieved if this function is active.
Note Estimating distances correctly
Objects reflected in the mirror are closer
than they appear. Do not estimate the distance
to the traffic behind you based on what you
see in the mirror, as this will increase your risk
of an accident.◀

Selecting a mirror
To change over to the other mirror:
Slide the switch.
Adjusting electrically
The setting corresponds to the direc‐
tion in which the button is pressed.
Saving positions
Seat, mirror, and steering wheel memory, refer
to page 61.
Adjusting manually In case of electrical malfunction press edges of
mirror.
Automatic Curb Monitor
The concept
If reverse gear is engaged, the mirror glass on
the front passenger side is tilted downward.
This improves your view of the curb and other
low-lying obstacles when parking, e.g.
Activating1. Slide the switch to the driver's side
mirror position.2.Engage selector lever position R.
Deactivating
Slide the switch to the passenger side mirror
position.
Fold in and out Press button.
Possible at speeds up to approx.
15 mph/20 km/h.
E. g. this is advantageous
▷In car washes.▷In narrow streets.▷For folding mirrors back out that were
folded away manually.Seite 62ControlsAdjusting62

wash, e.g., ensure that the ignition is not
switched off accidentally.◀
The ignition automatically cuts off while the
vehicle is stationary and the engine is stopped:▷When locking the vehicle, and when the
low beams are activated.▷Shortly before the battery is discharged
completely, so that the engine can still be
started. This function is only available
when the low beams are turned off.▷When opening or closing the driver door, if
the driver's safety belt is unbuckled and
the low beams are turned off.▷While the driver's safety belt is unbuckled

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.
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.
A Check Control message is displayed.
Steptronic transmission
