With front axle damage
\1
Turn the key to position
1 in the igni-
tion lock(
\2
page 111).
In the event of a malfunction in the
electrical systemIf the battery is malfunctioning, the auto-
matic transmission will be locked in
position
P. To shift the automatic trans-
mission to position
N, you must provide
power to the vehicle’s electrical system
in the same way as jump-starting
(
\2
page 581).
Have the vehicle transported on a trans-
porter or trailer.The towing eye can be used to pull the
vehicle onto a special transporter or
trailer for transportation.
\1
Shift the transmission to neutral or
move the selector lever to
position
N.
!
CAUTION
The vehicle must not be towed with
its front wheels raised and with the
key in position
2 in the ignition lock.
Active brake intervention by ESP
® or
ASR could otherwise lock the wheels
and damage the brake system.
Transporting the vehicle!
CAUTION
Only secure the vehicle at the
wheels / rims. Your vehicle could oth-
erwise be damaged.

INSTALLATION OF RADIO TRANSMITTING
EQUIPMENT
Special design considerations are incorporated into this
vehicle's electronic system to provide immunity to radio
frequency signals. Mobile two-way radios and telephone
equipment must be installed properly by trained person-
nel. The following must be observed during installation.
The positive power connection should be made directly
to the battery and fused as close to the battery as possible.
The negative power connection should be made to body
sheet metal adjacent to the negative battery connection.
This connection should not be fused.
Antennas for two-way radios should be mounted on the
roof or the rear area of the vehicle. Care should be used
in mounting antennas with magnet bases. Magnets may
affect the accuracy or operation of the compass on
vehicles so equipped.The antenna cable should be as short as practical and
routed away from the vehicle wiring when possible. Use
only fully shielded coaxial cable.
Carefully match the antenna and cable to the radio to
ensure a low Standing Wave Ratio (SWR).
Mobile radio equipment with output power greater than
normal may require special precautions.
All installations should be checked for possible interfer-
ence between the communications equipment and the
vehicle's electronic systems.
