Driving systems
Parktronic system (Parking assist)*
The Parktronic system is an electronic aid
designed to assist the driver during park-
ing maneuvers. It visually and audibly indi-
cates the relative distance between the
vehicle and an obstacle.
The Parktronic system is automatically ac-
tivated when you switch on the ignition, re-
lease the parking brake, and placed the
gear selector lever in positionD,R,orN.
The Parktronic system deactivates at
speeds over approximately 11 mph
(18 km/h). At lower speeds the Parktronic
system turns on again.
The Parktronic system also deactivates
when you place the gear selector lever in
positionP or depress the parking brake
pedal.The Parktronic system monitors the sur-
roundings of your vehicle with six sensors
in the front bumper and four sensors in the
rear bumper.
1Sensors in the front bumper
Range of the sensors
To function properly, the sensors must be
free of dirt, ice, snow and slush. Clean the
sensors regularly, being careful not to
scratch or damage the sensors, see
“Cleaning the Parktronic system* sensors”
(
page 373).
Warning!
G
Parktronic is a supplemental system. It is
not intended to, nor does it replace, the
need for extreme care. The responsibility
during parking and other critical maneuvers
always rests with the driver.
Special attention must be paid to objects
with smooth surfaces or low silhouettes
(e.g. trailer couplings, painted posts, or road
curbs). Such objects may not be detected by
the system and can damage the vehicle.
The operational function of the Parktronic
system can be affected by dirty sensors, es-
pecially at times of snow and ice, see
“Cleaning the Parktronic system* sensors”
(page 373).
Interference caused by other ultrasonic sig-
nals (e.g. working jackhammers, car wash or
the air brakes of trucks) can cause the sys-
tem to send erratic indications, and should
be taken into consideration.
Warning!
G
Make sure no persons or animals are in the
area in which you are maneuvering. You
could otherwise injure them.

The lighter socket can be used to accommo-
date 12 V DC electrical accessories (up to a
maximum of 85 W) designed for use with the
standard “cigarette lighter” plug type. Keep in
mind, however, that connecting accessories to
the lighter socket (for example extensive con-
necting and disconnecting, or using plugs that do
not fit properly) can damage the lighter socket.
With the socket damaged, the lighter may no
longer be able to be placed in the heating
(pushed-in) position, or the lighter may pop out
too early with the lighter not hot enough.
To help avoid damaging the cigarette lighter
socket, we recommend connecting 12 V DC
electrical accessories designed for use with a
standard “cigarette lighter” plug type to the 12 V
power outlets in your vehicle whenever possible.

Programming the integrated remote
control
Step 1:
Switch on the ignition (
page 37).Step 2:

If you have previously programmed a
signal transmitter button and wish to
retain its programming, proceed to
step 3.
If you are programming the integrated
remote control for the first time, press
and hold the two outer signal transmit-
ter buttons2 and4 and release
them only when the indicator lamp1
begins to flash after approximately
20 seconds (do not hold the button for
longer than 30 seconds). This proce-
dure erases any previous settings for
all three channels and initializes the
memory.
If you later wish to program a second
and/or third hand-held transmitter to
the remaining two signal transmitter
buttons, do not repeat this step and be-
gin directly with step 3.
Warning!
G
Before programming the integrated remote
control to a garage door opener or gate
operator, make sure people and objects are
out of the way of the device to prevent po-
tential harm or damage. When programming
a garage door opener, the door moves up or
down. When programming a gate operator,
the gate opens or closes.
Do not use the integrated remote control
with any garage door opener that lacks
safety stop and reverse features as required
by U.S. federal safety standards (this
includes any garage door opener model
manufactured before April 1, 1982).
A garage door that cannot detect an object
- signaling the door to stop and reverse -
does not meet current U.S. federal safety
standards.
When programming a garage door opener,
park vehicle outside the garage.
Do not run the engine while programming
the integrated remote control. Inhalation of
exhaust gas is hazardous to your health. All
exhaust gas contains carbon monoxide
(CO), and inhaling it can cause unconscious-
ness and possible death.

Reprogramming a single signal trans-
mitter button
To program a device using a signal trans-
mitter button previously trained, follow
these steps:
Switch on the ignition (
page 37).

Press and hold the desired signal
transmitter button (2, 3 or4).
Do not release the button.

Indicator lamp1 will begin to flash af-
ter 20 seconds. Without releasing the
signal transmitter button, proceed with
programming starting with step 3.Operation of integrated remote control

Switch on the ignition (
page 37).

Select and press the appropriate inte-
grated signal transmitter button (2,
3 or4) to activate the remote con-
trolled device.
The integrated remote control trans-
mitter continues to send the signal as
long as the button is pressed – up to
20 seconds.
Erasing the integrated remote control
memory

Switch on the ignition (
page 37).

Simultaneously press and hold outer
signal transmitter buttons2 and 4,
for approximately 20 seconds, until
indicator lamp1 flashes rapidly. Do
not hold for longer than 30 seconds.
The codes of all three channels are
erased.Programming tips
If you are having difficulty programming
the integrated remote control, here are
some helpful tips:


Check the frequency of hand-held re-
mote control5 (typically located on
the reverse side of the remote). The in-
tegrated remote control is compatible
with radio-frequency devices operating
between 280-390 MHz.


Put a new battery in hand-held remote
control5. This will increase the likeli-
hood of the hand-held remote control
sending a faster and more accurate sig-
nal to the integrated remote control.


While performing step 3, hold
hand-held remote control5 at differ-
ent lengths and angles from the signal
transmitter button (2, 3 or4) you
are programming. Attempt varying an-
gles at the distance of 2 to 5 inches
(5 to 12 cm) away or the same angle at
varying distances.
i
Upon completion of programming the inte-
grated remote control, make sure you retain the
hand-held remote control that came with the ga-
rage door opener, gate operator or other device.
You may need it for use in other vehicles, for fu-
ture programming of an integrated remote con-
trol, or simply for continued use as a hand-held
remote control to operate the respective device
in other situations.
i
If you sell your vehicle, erase the codes of all
three channels.
