If you live in Canada or if you are having
difficulties programming a gate operator
(regardless of where you live) by using the
programming procedures, replace step 4
with the following:
Step 4:
Press and hold the signal transmitter
button (2,3 , or 4). Do not release
this button until it has been success-
fully trained.
While still holding down the signal
transmitter button ( 2, 3 or 4),
“cycle” your hand-held remote control
button 6 as follows: Press and hold
button 6 for 2 seconds, then release
it for 2 seconds, and again press and
hold it for 2 seconds. Repeat this
sequence on the hand-held remote
control until the frequency signal has
been learned. Upon successful train-
ing, indicator lamp 1 will flash slowly
and then rapidly after several seconds.
Proceed with programming step 5 and
step 6 to complete. Reprogramming a single signal
transmitter button
To program a device using a signal trans-
mitter button previously trained, follow
these steps:
Switch on the ignition (page 39).
Press and hold the desired signal
transmitter button (
2, 3 , or 4).
Do not release the button.
Indicator lamp 1 will begin to flash
after 20 seconds. Without releasing the
signal transmitter button, proceed with
programming starti ng with step 3. Operation of integrated remote control
Switch on the ignition (page 39).
Select and press the appropriate signal
transmitter button (
2, 3 , or 4) to
activate the remote controlled device.
The integrated remote control
transmitter continues to send the
signal as long as the button is
pressed – up to 20seconds.
Erasing the integrated remote control
memory
Switch on the ignition (page 39).
Simultaneously press and hold outer
signal transmitter buttons 2 and 4,
for approximately 20 seconds, until
indicator lamp 1 b l i n k s r a p i d l y . D o n o t
hold for longer than 30 seconds.
The codes of all three channels are
erased.
iUpon completion of programming the
integrated remote control, make sure you retain
the hand-held remote control that came with the
garage door opener, gate operator or other
device. You may need it for use in other vehicles,
for future programming of an integrated remote
control, or simply for continued use as a
hand-held remote control to operate the
respective device in other situations.
iIf you sell your vehicle, erase the codes of all
three channels.

Programming tips
If you are having difficulty programming
the integrated remote control, here are
some helpful tips:

Check the frequency of hand-held
remote control
5 (typically located on
the reverse side of the remote). The
integrated remote control is compati-
ble with radio-frequency devices oper-
ating between 280-390 MHz.

Put a new battery in hand-held remote
control 5. This will increase the
likelihood of the hand-held remote con-
trol sending a faster and more accurate
signal to the integrated remote control.

While performing step 3, hold
hand-held remote control 5 at
different lengths and angles from the
signal transmitter button ( 2, 3 or 4)
you are programming. Attempt varying
angles at the distance of 2 to 5 in
(5 to 12 cm) away or the same angle at
varying distances.

If another hand-held remote control is
available for the same device, try the
programming steps again using that
other hand-held remote control. Make
sure new batteries are in the hand-held
remote control before beginning the
procedure.

Straighten the antenna wire from the
garage door opener assembly. This
may help improve transmitting and/or
receiving signals.
iCertain types of garage door openers are
incompatible with the integrated remote control.
If you should experience further difficulties with
programming the integrated remote control,
contact an authorized Mercedes-Benz Light
Truck Center, or call Mercedes-Benz Customer
Assistance Center (in the USA only) at
1-800-FOR-MERCedes, or Customer Service
(in Canada) at 1-800-387-0100.

244 Operation
In the “Operation” section you will find
detailed information on operating, main-
taining and caring for your vehicle.
The first 1 000 miles (1 500 km)
The more cautiously you treat your vehicle
during the break-in period, the more satis-
fied you will be with its performance later
on.

Drive your vehicle during the first
1 000 miles (1 500 km) at varying but
moderate vehicle and engine speeds.

During this period, avoid heavy loads
(full throttle driving) and excessive
engine speeds (no more than
2/3 of
maximum rpm in each gear).

Shift gears in a timely manner.

Avoid accelerating by kick-down.

Do not attempt to slow the vehicle
down by shifting to a lower gear using
the gear selector lever.

Select gear ranges 3, 2 , or 1
(
page 167) only when driving at
moderate speeds (for hill driving).
After 1 000 miles (1 500 km) you may
gradually increase vehicle and engine
speeds to the permissible maximum. All of the above instructions, as may apply
to your vehicle type, also apply when
driving the first 1 000 miles (1 500 km)
after the engine, the transfer case, the
front differential or th
e rear differential has
been replaced.
!Additional instructions for AMG vehicles:

During the first 1 000 miles (1 500 km), do
not exceed a speed of 85 mph (140 km/h).

During this period, avoid engine speeds
above 4 500 rpm in each gear.
iG55AMG:
For better protection of the front and rear differ-
ential, the oil must be changed after a break-in
period of 1 900 miles (3 000 km).
Changing the oil in the front and rear differential
increases the service life and helps reduce noise
from the differential locks.
See Maintenance Booklet for additional infor-
mation and Factory Approved Service Products
pamphlet (USA only) for information on the
approved service product required to perform
the front and rear axle oil change.
iAlways obey applicable speed limits.

Drive sensibly – save fuel
Fuel consumption, to a great extent,
depends on driving habits and operating
conditions.
To save fuel you should:

Keep tires at the recommended infla-
tion pressures.

Remove unnecessary loads.

Allow engine to warm up under low
load use.

Avoid frequent acceleration and decel-
eration.

Have all maintenance work performed
at the intervals specified in the
Maintenance Booklet and as required
by the Maintenance System. Contact
an authorized Mercedes-Benz Light
Truck Center.
Fuel consumption is also increased by
driving in cold weather, in stop-and-go
traffic, on short trips and in hilly area.
Drinking and drivingPedals
Warning!G
Drinking and driving and/or taking drugs
and driving are very dangerous combina-
tions. Even a small amount of alcohol or
drugs can affect your reflexes, perceptions
and judgment.
The possibility of a se rious or even fatal
accident are greatly increased when you
drink or take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or
taking drugs.
Warning!G
Make sure that absolutely no objects are
obstructing the pedal’s range of movement.
Keep the driver’s footwell clear of all obsta-
cles. If there are any floormats or carpets in
the footwell, make sure that the pedals still
have sufficient clearance.
During sudden driving or braking maneu-
vers, the objects could get caught between
the pedals. You could th en no longer brake
or accelerate. This could lead to accidents
and injury.

Driving instructions
Power assistance
BrakesTo help prevent brake disk corrosion after
driving on wet road surfaces (particularly
salted roads), it is advisable to brake the
vehicle with considerable force prior to
parking. The heat generated serves to dry
the brakes.
If your brake system is normally only
subjected to moderate loads, you should
occasionally test the effectiveness of the
brakes by applying above-normal braking
pressure at higher speeds. This will also
enhance the grip of the brake pads.
Warning!G
With the engine not running, there is no
power assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the
vehicle.
Warning!G
After driving in heavy
rain for some time
without applying the brakes or through
water deep enough to wet brake compo-
nents or salty road conditions, the first brak-
ing action may be somewhat reduced and
increased pedal pressure may be necessary
to obtain expected br aking effect. Maintain
a safe distance from vehicles in front.
Resting your foot on the brake pedal will
cause excessive and premature wear of the
brake pads.
It can also result in the brakes overheating,
thereby significantly reducing their effec-
tiveness. It may not be possible to stop the
vehicle in sufficient ti me to avoid an acci-
dent.
!Operational or performance test must only
be conducted on a two-axle dynamometer. If
such tests are necessary, contact an authorized
Mercedes-Benz Light Truck Center. You could
otherwise seriously damage the brake system or
the transfer case which is not covered by the
Mercedes-Benz Limited Warranty.
!Because the ESP® operates automatically,
the engine and ignition must be shut off
(SmartKey in starter switch position 0 or 1)
when testing the parking brake on a brake test
dynamometer and such testing should be no
longer than 10 seconds.
Active braking action through the ESP
® may
otherwise seriously damage the brake system
which is not covered by the Mercedes-Benz
Limited Warranty.
Warning!G
Make sure not to endanger any other road
users when carrying out these braking
maneuvers.

Operation
Driving instructions
Refer to the description of the Brake Assist
System (BAS) (
page 89).
Brake pad wear or a leak in the system may
be the reason for low brake fluid in the
reservoir.
The brake fluid level in the reservoir may
be too low if the brake warning lamp in the
instrument cluster comes on although the
parking brake is released (
page 326).
Observe additional messages in the
multifunction display that may appear
(
page 336).
Have the brake system inspected
immediately. Contact an authorized
Mercedes-Benz Light Truck Center.
All checks and service work on the brake
system should be carried out by qualified
technicians only. Contact an authorized
Mercedes-Benz Light Truck Center.
Only install brake pads and brake fluid
recommended by Mercedes-Benz. After hard braking, it is advisable to drive
on for some time, rather than immediately
park, so the air stream will cool down the
brakes faster.
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
operating temperature has been reached.
To ensure sufficient traction during
off-road driving, activate differential locks
as needed (
page 175).
Warning!G
If other than recommended brake pads are
installed, or other than recommended brake
fluid is used, the braking properties of the
vehicle can be degraded to an extent that
safe braking is substa ntially impaired. This
could result in an accident.
!When driving down long and steep grades,
relieve the load on the brakes by shifting into a
lower gear to use the engine’s braking power.
This helps prevent overheating of the brakes and
reduces brake pad wear.
!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
Warranty.
!Simultaneously depressing the accelerator
pedal and applying the brake reduces engine
performance and causes premature brake and
drivetrain wear.
