by local radio waves, such as by a mobile phone
in the immediate vicinity of the remote control or
when a mobile phone is being charged in the
vehicle.
If this occurs, open or close the vehicle using the
buttons on the remote control or use the
integrated key in the door lock.
To start the engine afterward, insert the remote
control into the ignition switch.
Warning lamps The warning lamp in the instrument
cluster lights up when you attempt to
start the engine: the engine cannot be
started.
The remote control is not in the vehicle or has a
malfunction. Take the remote control with you
inside the vehicle or have it checked. If neces‐
sary, insert another remote control into the ig‐
nition switch.
The warning lamp in the instrument
cluster lights up while the engine is
running: the remote control is no lon‐
ger inside the vehicle.
After switching off the engine, the engine can
only be started again within approx. 10 seconds
if no door has been opened.
The indicator lamp in the instrument
cluster comes on and a message ap‐
pears on the Control Display: replace
the remote control battery.Replacing the battery
The remote control for Comfort Access con‐
tains a battery that will need to be replaced from
time to time.1.Take the integrated key out of the remote

tomatic engine start/stop function no
longer switches of the engine auto‐
matically.A message appears on the Control
Display. It is possible to continue driving. Have
the system checked.
Handbrake
The concept
The handbrake is primarily intended to prevent
the vehicle from rolling while parked; it brakes
the rear wheels.

The indicator lamp lights up and an
acoustic signal sounds when driving
away. The handbrake is still set.
Setting
The lever engages automatically.
Releasing
Pull up slightly, press the button, and lower the
lever.
Notes Using the handbrake while driving
If it should become necessary to use the
handbrake while driving, do not pull the hand‐
brake too forcefully. Keep the button on the
handbrake lever pressed at all times.
Excessive application of the handbrake can
block the rear wheels and lead to fishtailing of
the vehicle.◀
To prevent corrosion and uneven brake action,
lightly apply the handbrake from time to time
when coasting, traffic conditions permitting.
The brake lamps do not light up when the hand‐
brake is pulled.

Check Control
The concept
The Check Control monitors vehicle functions
and alerts you to any malfunctions in the sys‐
tems monitored.
A Check Control message consists of indicator
and warning lamps in the instrument cluster and,
in some circumstances, an acoustic signal and
text messages at the top of the Control Display.
Indicator/warning lamps
The indicator and warning lamps can light up in
a variety of combinations and colors.
Several of the lamps are checked for proper
functioning and light up temporarily when the
engine is started or the ignition is switched on.

messages have been stored. The Check Control
messages can be displayed later.
Text messages
Text messages at the upper edge of the Control
Display in combination with a symbol in the in‐
strument cluster explain a Check Control mes‐
sage and the meaning of the indicator and warn‐
ing lamps.
Supplementary text messages
Addition information, such as on the cause of a
fault or the required action, can be called up via

The turning lamps are automatically switched
on depending on the steering angle or the use
of turn signals.
To avoid blinding oncoming traffic, the Adaptive
Light Control does not swivel to the driver's side
when the vehicle is at a standstill.
When driving in reverse, both turning lamps are
active.
Malfunction The warning lamp lights up.A mes‐
sage appears on the Control Display.
Adaptive light control is malfunction‐
ing or has failed. Have the system checked as

After parking the vehicle, press the lever up or
down beyond the resistance point for ap‐
prox. 2 seconds, arrow 3.
The roadside parking lamps drain the battery.
Therefore, do not leave them on for unduly long
periods of time; otherwise, the battery might not
have enough power to start the engine.
Switching off
Briefly press the lever in the opposite direction
to the pressure point, arrow 3.
High-beam Assistant
The concept
When the lights are switched on, this system
automatically switches the high beams on and
off. The procedure is controlled by a sensor on
the front of the interior rearview mirror. The as‐
sistant ensures that the high beams are
switched on whenever the traffic situation al‐
lows. The driver can intervene at any time and
switch the high beams on and off as usual.
Activating the High-beam Assistant1.Turn the light switch to .2.With the low beams switched on, briefly
push the turn indicator lever in the direction
of the high beam.
The indicator lamp in the instrument
cluster lights up. The high beams are
switched on and off automatically.
The system responds to light from oncoming
traffic and traffic driving ahead of you, and to ad‐
equate illumination, e.g., in towns and cities.

Indication of a flat tire The warning lamp lights up red. A
message appears on the Control Dis‐
play. In addition, a signal sounds.
There is a flat tire or a major loss in tire inflation
pressure.
Reduce your speed and stop cautiously. Avoid
sudden braking and steering maneuvers.
Do not continue driving without run-flat
tires
Do not continue driving if the vehicle is not
equipped with run-flat tires; continued driving
may result in serious accidents.◀
When a flat tire is indicated, DSC Dynamic Sta‐
bility Control is switched on if necessary.
Actions in the event of a flat tire
Run-flat tires
Maximum speed
You can continue driving with a damaged tire at
speeds up to 50 mph/80 km/h.
Continued driving with a flat tire
If continuing to drive with a damaged tire:1.Avoid sudden braking and steering maneu‐
vers.2.Do not exceed a speed of 50 mph/80 km/h.3.At the next opportunity, check the inflation
pressure in all four tires.
If the tire inflation pressure in all four tires is
correct, the Flat Tire Monitor may not have
been initialized. In this case, initialize the
system.
Possible driving distance with complete loss of
tire inflation pressure:
The possible driving distance after a loss of tire
inflation pressure depends on the cargo load
and the driving style and conditions.
For a vehicle containing an average load, the
possible driving distance is ap‐
prox. 50 miles/80 km.
When the vehicle is driven with a damaged tire,
its handling characteristics change, e.g., re‐
duced lane stability during braking, a longer
braking distance, and altered self-steering
properties. Adjust your driving style accord‐
ingly. Avoid abrupt steering maneuvers or driv‐
ing over obstacles, e. g., curbs, potholes, etc.
Because the possible driving distance depends
on how the vehicle is used during the trip, the
actual distance may be smaller or greater de‐
pending on the driving speed, road conditions,
external temperature, cargo load, etc.
Continued driving with a flat tire
Drive moderately and do not exceed a
speed of 50 mph/80 km/h.
A loss of tire inflation pressure results in a
change in the handling characteristics, e.g., re‐
duced lane stability during braking, a longer
braking distance and altered self-steering prop‐
erties.◀

After driving for a few minutes, the set tire infla‐
tion pressures are applied as set values. The re‐
setting process is completed automatically as
you drive. The tires are shown in green and
"TPM active" is shown on the Control Display.
The trip can be interrupted at any time. If you
drive away again, the process resumes auto‐
matically.
If a flat tire is detected while the system is re‐
setting, all tires on the Control Display are dis‐
played in yellow. The message "Low tire!" is
shown.
Low tire pressure message The small warning lamp lights up yel‐
low and the large warning lamp lights
up red. A message appears on the
Control Display. In addition, a signal
sounds.
▷There is a flat tire or a major loss in tire in‐
flation pressure.▷The system was not reset after a wheel
change and thus issues warnings based on
the inflation pressures initialized last.
Reduce your speed and stop cautiously. Avoid
sudden braking and steering maneuvers.
Do not continue driving without run-flat
tires
Do not continue driving if the vehicle is not
equipped with run-flat tires; continued driving
may result in serious accidents.◀
