187 Control systems
COMAND navigation (introduction)
General notes
Operational readiness of the navigation
system following a system software
update by an authorized
Mercedes-Benz Center
After a system software update by an au-
thorized Mercedes-Benz Center, the in-
stalled map software may no longer be
compatible. If this is the case, the naviga-
tion system will not be operational.
You will know if this is the case, when the
following message will appear when you
switch to navigation mode: “The system
software has been updated. The map soft-
ware must be updated now. Please insert
the DVD with the map software.”
Updating map software: Proceed as
described in the “Updating the map
software” section (
page 183). Use
map software which is compatible with
the system software.Initial use or use following a system
software update
In both these cases, the navigation system
must determine the position of the vehicle.
You may have to drive for a while before
precise route guidance is possible.
GPS reception
Correct functioning of the navigation sys-
tem depends on GPS reception, among
other things. In certain situations, GPS re-
ception may be impaired, there may be in-
terference or no reception at all, e.g. in
tunnels, in multistory parking garages or
there is snow covering the trunk lid where
the GPS antenna is located. If there is
snow on the trunk lid it should be removed.Route guidance after vehicle transpor-
tation
COMAND has to redetermine the position
of the vehicle if the vehicle has been trans-
ported (e.g. by ferry, by train or after tow-
ing).
Positioning takes place automatically even
when COMAND is switched off. The dura-
tion varies from one case to another.
Route guidance may be restricted as fol-
lows during vehicle positioning:


Navigation announcements, route
guidance displays and displayed street
names are not consistent with the ac-
tual location of the vehicle.


COMAND does not generate navigation
announcements.


Instead of the route guidance displays,
you see the “Off Road” display and a di-
rection arrow. The direction arrow
shows the compass heading to the des-
tination.
i
Please note that the update must be allowed
to run to the end in this case. If you interrupt it,
the navigation system will continue to be non-op-
erational.

423 Controls in detail
Automatic transmission
Vehicles with SmartKey:
With the vehicle at a standstill and the
ignition switched on shift the
automatic transmission to neutral
positionN.

If engaged, manually release the
electronic parking brake (
page 413).

Switch off the ignition and leave the
SmartKey in the starter switch.
Vehicles with KEYLESS-GO*:

With the vehicle at a standstill, depress
the brake pedal and keep it pressed.

With the ignition switched on shift the
automatic transmission to park
positionP.

Release the brake pedal.

Remove the KEYLESS-GO start/stop
button from the starter switch
(page 366).

Insert the SmartKey with KEYLESS-GO
into the starter switch.

Switch on the ignition.

Depress the brake pedal.

Shift the automatic transmission to
neutral positionN.

Release the brake pedal.

If engaged, manually release the
electronic parking brake (
page 413).

Switch off the ignition and leave the
SmartKey with KEYLESS-GO in the
starter switch.
!
Coasting the vehicle, or driving for any other
reason in neutral positionN can result in trans-
mission damage that is not covered by the
Mercedes-Benz Limited Warranty.
!
Observe instructions


when taking the vehicle through an
automatic conveyor type car wash
(page 598)


when towing the vehicle (
page 710)
Effect
ê
Drive
The transmission shifts
automatically. All forward gears
are available.
Warning!
G
Getting out of your vehicle without shifting
into park positionP is dangerous. Also, park
positionP alone is not intended to or capa-
ble of preventing your vehicle from moving,
possibly hitting people or objects.
Always engage the electronic parking brake
(page 412) in addition to shifting to park
positionP.
When parked on an incline, turn the front
wheels towards the road curb.
Do not park this vehicle in areas where com-
bustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.

469 Controls in detail
Driving systems
The Park Assist system deactivates at
speeds over approximately 10 mph
(16 km/h). At lower speeds the Parktronic
system turns on again.
Park Assist is also switched off when you
set the automatic transmission to park
positionP or switch off the engine.
While the transmission is in neutral
positionN, Park Assist is switched off if
you secure the vehicle in place with the
electronic.
The Park Assist system monitors the sur-
roundings of your vehicle with four sensors
in the front bumper and two sensors in the
rear bumper.
Range of the sensors
The sensors of the Park Assist system are
integrated in the front and rear bumpers.
Make sure that the bumpers are clear of
dirt, ice and slush in the area of the sen-
sors, as otherwise, Park Assist may not
function properly, see “Cleaning the driv-
ing systems sensors” (
page 601).Front sensors
Rear sensors
i
Due to the sensors’ broad detection range,
it is possible that Park Assist also detects the fol-
lowing obstacles and issues a warning:


obstacles in the ground, e.g. sewer canal
covers, rails, bumps in the road or gutters


obstacles moving upward quickly, e.g. rolling
garage doors
Center
approx. 40 in (100 cm)
Corners
approx. 24 in (60 cm)
Center
approx. 50 in (125 cm)
Corners
approx. 24 in (60 cm)
!
While parking, pay particular attention to ob-
jects over or underneath the sensors, e.g. flower
boxes, an elevated crossbar or a trailer tow
hitch. Park Assist does not detect such nearby
objects. You could otherwise damage the vehicle
or the objects.

542 OperationDriving instructions
Driving off
Apply the brakes to test them briefly after
driving off. Perform this procedure only
when the road is clear of other traffic.
Warm up the engine smoothly. Do not
place full load on the engine until the oper-
ating temperature has been reached.
Parking
Warning!
G
New vehicle brake pads and discs, and
replacement brake pads and discs may take
several hundred miles of driving until they
provide optimum braking efficiency. Until
that time, you may need to use increased
brake pedal pressure while braking. Please
be aware of this and adjust your driving and
braking accordingly during this break-in
period.
Excessive high demand braking will cause
correspondingly high brake wear. Please be
attentive to the brake warning lamp in the
instrument cluster and brake condition mes-
sages in the multifunction display. Especial-
ly for high performance driving, it is
important to maintain and have the brake
system checked regularly.
!
When driving off on a slippery surface, do
not allow a drive wheel to spin for an extended
period with the ESP
® switched off. Doing so may
cause serious damage to the drivetrain which is
not covered by the Mercedes-Benz Limited War-
ranty.
!
Simultaneously depressing the accelerator
pedal and applying the brakes reduces engine
performance and causes premature brake wear
and drivetrain wear.
Warning!
G
Do not park this vehicle in areas where com-
bustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.
To reduce the risk of personal injury, or
damage to the vehicle drivetrain, as a result
of inadvertent vehicle movement, before
turning off the engine and leaving the vehi-
cle always:

Keep right foot on brake pedal.


Engage electronic parking brake.


Shift the automatic transmission toP.


Slowly release brake pedal.


When parked on an incline, turn front
wheels towards the road curb.

707 Practical hints
Jump starting
Jump starting
If the starter battery is discharged, the en-
gine can be started with jumper cables and
the battery of another vehicle. Observe the
following:

Jump starting should only be performed
when the engine and catalytic convert-
er are cold.


Do not start the engine if the battery is
frozen. Let the battery thaw out first.


Only use 12-volt battery to jump start
your vehicle. Jump starting with a high-
er voltage battery could damage the ve-
hicle’s electrical system, which will not
be covered by the Mercedes-Benz Lim-
ited Warranty.


Only use jumper cables with sufficient
cross-section and insulated terminal
clamps.


Always make sure that the jumper ca-
bles are not on or near pulleys, fans or
other parts that move when an engine
is started or running.
Warning!
G
Failure to follow these directions will cause
damage to the electronic components, and
can lead to a battery explosion and severe
injury or death.
Never lean over batteries while connecting
or jump starting, you might get injured.
Battery fluid contains sulfuric acid. Do not
allow this fluid to come in contact with eyes,
skin or clothing. In case it does, immediately
flush affected area with water, and seek
medical help if necessary.
A battery will also produce hydrogen gas,
which is flammable and very explosive. Keep
flames or sparks away from battery, avoid
improper connection of jumper cables,
smoking, etc.
Attempting to jump start a frozen battery
can result in it exploding, causing personal
injury.
Read all instructions before proceeding.
!
Do not tow-start the vehicle.
!
Jump starting should only be performed on
the starter battery installed in the engine com-
partment.
Avoid repeated and lengthy starting attempts.
Do not attempt to start the engine using a bat-
tery quick charge unit.
If engine does not run after several unsuccessful
starting attempts, have it checked at the nearest
authorized Mercedes-Benz Center.
Excessive unburned fuel generated by repeated
failed starting attempts may damage the catalyt-
ic converter and may present a fire risk.
Make sure the jumper cables do not have loose
or missing insulation.
Make sure the cable clamps do not touch any
other metal part while the other end is still at-
tached to a battery.
