KEYLESS-GO
General notes
Vehicles with KEYLESS-GO are equipped with a
SmartKey featuring an integrated KEYLESS-GO
start function and adetachable Start/Stop but-
ton.
The Start/Stop button must be inserted in the
ignition lock and the SmartKey must be in the
vehicle.
When you insert the Start/Stop button into the
ignition lock, the system needs approximately
two seconds recognition time. You can then use
the Start/Stop button.
Pressing the Start/Stop button several times in
succession corresponds to the differentk ey
positions in the ignition lock. This is only the
case if you are not depressing the brake pedal. If you depress the brake pedal and press the
Start/Stop button
,the engine start simmedi-
ately.
Ac heck which periodically establishes aradio
connection between the vehicle and the Smart-
Key determines whether avalid SmartKey is in
the vehicle. This occurs,f or example, when
starting the engine.
To start the vehicle without actively using the
SmartKey:
Rthe Start/Stop button must be inserted in the
ignition lock.
Rthe SmartKey must be in the vehicle.
Rthe vehicle must not be locked with the
SmartKey or KEYLESS-GO (Ypage 63).
Do not keep the SmartKey:
Rwith electronic devices, e.g. amobile phone
or another SmartKey.
Rwith metallic objects, e.g. coins or metal foil.
Rinside metallic objects, e.g. ametal case.
This can impair the functionality of the KEY-
LESS-GO key.
If you lock the vehicle with the SmartKey's
remotec ontrol or with KEYLESS-GO, after a
short time:
Ryou will not be able to switch on the ignition
with the Start/Stop button.
Ryou will not be able to start the engine with the
Start/Stop button until the vehicle is
unlocked again.
The engine can be switched off while the vehicle
is in motion by pressing and holding the Start/
Stop button for three seconds. This function
operates independently of the ECO start/stop
automatic engine switch-off function.

Parking Guidance
Important safety notes
Parking Guidance is an electronic parking aid
with ultrasound. Ultrasound is used to measure
the road on both sides of the vehicle. Asuitable
parking space is indicated by the parking sym-
bol. You receive steering instructions when
parking. You may also use PARKTRONIC
(
Ypage 149).
Parking Guidance is only an aid. It is not a
replacement for your attention to your immedi-
ate surroundings. You are always responsible
for safe maneuvering, parking and exiting a
parking space. When maneuvering, parking or
pulling out of aparking space, make sure that
there are no persons, animals or object sinthe
area in which you are maneuvering.
GWARNING
If object sare located above the detection
range, Parking Guidance may provide steering
instructions too soon. You may cause acolli-
sion as aresult. There is arisk of an accident.
If object sare located above the detection
range, stop and switch off Parking Assist.
!If unavoidable, you should drive over obsta-
cles such as curbs slowly and not at asharp
angle. Otherwise, you may damage the
wheels or tires.
When PARKTRONIC is deactivated, Parking
Guidance is also unavailable.
Parking Guidance may also display spaces not
suitable for parking, e.g.:
Rwhere parking or stopping is prohibited
Rin front of driveways or entrances and exits
Ron unsuitable surfaces
Use Parking Guidance for parking spaces:
Rthat are paralleltot he direction of travel
Rthat are on straight roads, not bends
Rthat are on the same level as the road, i.e. not
on the pavement, for example. Parking Guid-
ance may not detect flat curbs
Parking tips:
ROn narrow roads, drive as close to the parking
space as possible.
RParking spaces that are littered or overgrown
might be identified or measured incorrectly.
RParking spaces that are partially occupied by
trailer drawbars might not be identified as
such or be measured incorrectly.

In addition to the warning lamp,amessage
appears in the multifunction display. Observe
the information on display messages
(
Ypage 196).
It may take up to ten minutes for amalfunction
of the tire pressure monitor to be indicated .A
malfunction wil lbeindicated by the tire pres-
sure warning lamp flashing for approximately
one minute and then remaining lit. When the
malfunction has been rectified, the tire pressure
warning lamp goes out after afew minutes of
driving.
The tire pressure values indicated by the on-
board computer may differ from those meas-
ured at agas station with apressure gauge. The
tire pressures shown by the on-board computer
refer to those measured at sea level.Ath igh
altitudes, the tire pressure values indicated by a
pressure gauge are higher than those shown by the on-board computer. In this case, do not
reduce the tire pressures.
The operation of the tire pressure monitor can
be affected by interference from radi otransmit-
ting equipment (e.g. radi oheadphones, two-way
radios) that may be being operated in or near the vehicle.
Checking the tire pressure electroni-
cally

If an emergency spare wheel is mounted, the
system may continue to show the tire pressure of the wheel that has been removed for

played for the positionw here the spare wheel is
mounted is not the same as the current tire
pressure of the emergency spare wheel.

If the tire pressure monitor detects apressure
loss in one or more tires, awarning messag eis
shown in the multifunction display. The yellow
tire pressure warning lamp then lights up.
RIf the Please Correct Tire Pressuremessag eappears in the multifunction display,
the tire pressure in at least one tire is too low.
The tire pressure must be corrected when the
opportunity arises.
RIf the Check Tiresmessag eappears in the

least one tire has droppeds ignificantly. The

RIf the WarningTireMalfunctionmessage

If the wheel positions on the vehicle are rotated,
the tire pressures may be displaye dfor the
wrong positions for ashort time. This is rectified
after afew minutes of driving, and the tire pres-
sures are displaye dfor the correct positions.
Restarting the tire pressure monitor
When you restart the tire pressure monitor, all
existing warning messages are deleted and the
warning lamp sgoout. The monitor uses the cur-
rently set tire pressures as the reference values for monitoring. In most cases, the tire pressure
monitor wil lautomatically detect the new refer-
ence values after you have changed the tire
pressure. However, you can also define refer-
ence values manually as describedh ere. The tire
pressure monitor then monitors the new tire
pressure values.
