Notes on programing the remote control
Canadian radio frequency laws require a
"break" (or interruption) of the transmission
signals after broadcasting for a few seconds.
Therefore, these signals may not last long
enough for the integrated garage door
opener. The signal is not recognized during
programing. Comparable with Canadian law,
some U.S. garage door openers also feature a
"break".
Proceed as follows:
Rif you live in Canada
Rif you have difficulties programing the
garage door opener (regardless of where
you live) when using the programing steps.
XPress and hold one of buttons ;to? on
the integrated garage door opener.
After a short time, indicator lamp :lights
up yellow.
XRelease the button.
Indicator lamp :flashes yellow.
XPress button Bof garage door remote
control Afor two seconds, then release it
for two seconds.
XPress button Bagain for two seconds.
XRepeat this sequence on button Bof
remote control Auntil indicator lamp :
lights up green.
When indicator lamp :lights up green:
programing is finished. When indicator lamp
:flashes green: pro-
graming was successful. The next step is to
synchronize the rolling code.
XRelease button Bof remote control Aof
the garage door drive.
If indicator lamp :lights up red: repeat the
programing process for the corresponding
button on the rear-view mirror. When doing
so, vary the distance between remote con-
trol Aand the rear-view mirror.
The required distance between remote
control Aand the integrated garage door
opener depends on the garage door drive
system. Several attempts might be neces-
sary. You should test every position for at
least 25 seconds before trying another
position.
Problems when programing
If you experience problems programing the
integrated garage door opener on the rear-
view mirror, take note of the following instruc-
tions:
RCheck the transmitter frequency used by
garage door drive remote control Aand
whether it is supported. The transmitter
frequency can usually be found on the back
of the garage door drive remote control.
The integrated garage door opener is com- patible with devices that have units which
operate in the frequency range of 280 to
433 MHz.
RReplace the batteries in garage door
remote control A. This increases the like-
lihood that garage door remote control A
will transmit a strong and precise signal to
the integrated garage door opener.
RWhen programing, hold remote control A
at varying distances and angles from the
button which you are programing. Try vari-
ous angles at a distance between 2and
12 inches (5to 30 cm) or at the same angle
but at varying distances.
RIf another remote control is available for the
same garage door drive, repeat the same
programing steps with this remote control.

!When towing, pull away slowly and
smoothly. If the tractive power is too high,
the vehicles could be damaged.
!The vehicle can be towed a maximum of
30 miles (50km). The towing speed of
30 mph (50km/h) must not be exceeded.
If the vehicle has to be towed more than
30 miles (50km), the front axle must be
raised or the entire vehicle raised and
transported.
!Do not tow with sling-type equipment.
This could damage the vehicle.
!To tow vehicles with KEYLESS-GO, use
the SmartKey instead of the Start/Stop
button. The transmission may otherwise
shift to position Pwhen you open the driv-
er's or front-passenger door, which could
damage the transmission.
Observe the legal requirements for the rele-
vant countries when towing away.
Make sure that no charging cable is plugged
in. The parking lock cannot be released if a
charging cable is plugged in.
It is better to have the vehicle transported
than to have it towed away.
If the vehicle can no longer be driven because
of an accident or breakdown, you have the
following options:
RTransporting the vehicle
As a rule, you should have the vehicle trans-
ported.
RTowing the vehicle with a tow rope or tow
bar
Only tow the vehicle in exceptional cases.
Observe the following notes.
The vehicle may not be towed and must
always be transported if:
Rthe multifunction display is not working
Rone of more of the following warning lamps
is lit up:
-Drive system
-12 V battery
Rone or both of the following display mes-
sages have appeared:
-Stop Switch Engine off
-Do Not Shift Gears Visit Dealer
Ryou have to tow the vehicle over a longer
distance than 30 miles (50 km).
The battery must be connected and charged.
Otherwise, you:
Rcannot turn the SmartKey to position 2in
the ignition lock
Rcannot release the electric parking brake
Rcannot shift the transmission to position N
The function of the electric parking brake and
the parking lock is dependent on the on-board voltage.
If the on-board voltage is low or there is a
system malfunction, it is possible that:
Rthe electric parking brake may not be
applied in certain circumstances, or
Rthe transmission may not be shifted to P
Switch off non-essential consumers, e.g. the
radio.
Disarm the automatic locking feature before
the vehicle is towed (
Ypage 198). You could
otherwise be locked out when pushing or
towing the vehicle.

sequence will be repeated every time the vehi-
cle is started as long as the malfunction
exists. When the malfunction indicator is illu-
minated, the system may not be able to detect
or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of incom-
patible replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one
or more tires or wheels on your vehicle to
ensure that the replacement or alternate Tires
and wheels allow the TPMS to continue to
function properly.
It is the driver's responsibility to set the tire
pressure to that recommended for cold tires
which is suitable for the operating situation
(
Ypage 305). Note that the correct tire pres-
sure for the current operating situation must
first be taught-in to the tire pressure monitor.
If there is a substantial loss of pressure, the
warning threshold for the warning message is
aligned to the reference values taught-in.
Restart the tire pressure monitor after adjust-
ing the pressure of the cold tires
(
Ypage 311). The current pressures are
saved as new reference values. As a result, a
warning message will appear if the tire pres-
sure drops significantly.
The tire pressure monitor does not warn you
of an incorrectly set tire pressure. Observe
the notes on the recommended tire pressure (
Ypage 305).
The tire pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the
tire is penetrated by a foreign object. In the
event of a sudden loss of pressure, bring the
vehicle to a halt by braking carefully. Avoid
abrupt steering movements. The tire pressure monitor has a yellow warn-
ing lamp in the instrument cluster for indicat-
ing pressure loss or a malfunction. Whether
the warning lamp flashes or lights up indi-
cates whether a tire pressure is too low or the
tire pressure monitor is malfunctioning:
Rif the warning lamp is lit continuously, the
tire pressure on one or more tires is signif-
icantly too low. The tire pressure monitor is
not malfunctioning.
Rif the warning lamp flashes for around a
minute and then remains lit constantly, the
tire pressure monitor is malfunctioning.
In addition to the warning lamp, a message
appears in the multifunction display. Observe
the information on display messages
(
Ypage 223).
It may take up to ten minutes for a malfunc-
tion of the tire pressure monitor to be indica-
ted. A malfunction will be indicated by the tire
pressure warning lamp flashing for approx-
imately one minute and then remaining lit.
When the malfunction has been rectified, the
tire pressure warning lamp goes out after a
few minutes of driving.
The tire pressure values indicated by the on-
board computer may differ from those meas-
ured at a gas station with a pressure gauge.
The tire pressures shown by the on-board
computer refer to those measured at sea
level. At high altitudes, the tire pressure val-
ues 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 radio trans-
mitting equipment (e.g. radio headphones,
two-way radios) that may be being operated
in or near the vehicle.

Instruction labels for tires and loads
GWARNING
Overloaded tires can overheat, causing a
blowout. Overloaded tires can also impair the steering and driving characteristics and lead
to brake failure. There is a risk of accident.
Observe the load rating of the tires. The load
rating must be at least half of the GAWR of
your vehicle. Never overload the tires by
exceeding the maximum load.
Two instruction labels on your vehicle show
the maximum possible load.
(1) The Tire and Loading Information placard is on the B-pillar on the driver's side. The
Tire and Loading Information placard
shows the maximum permissible numberof occupants and the maximum permis-
sible vehicle load. It also contains details
of the tire sizes and corresponding pres-
sures for tires mounted at the factory.
(2) The vehicle identification plate is on the B-pillar on the driver's side. The vehicle
identification plate informs you of the
gross vehicle weight rating. It is made up
of the vehicle weight, all vehicle occu-
pants, the fuel and the cargo. You can
also find information about the maximum
gross axle weight rating on the front and
rear axle.
The maximum gross axle weight rating is
the maximum weight that can be carried
by one axle (front or rear axle). Never
exceed the maximum load or the maxi-
mum gross axle weight rating for the
front or rear axle.
