2010 MERCEDES-BENZ R320 Owner's Manual

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:
X Step 4: Press and hold the signal
transmitter button ( ;, = or ?). Do not
release this button until it has been
successfully trained.
X While still holding down the signal
transmitter button ( ;, = or ?), “cycle”
your hand-held remote control button B
as follows: Press and hold button B 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 training, indicator
lamp : will flash slowly and then rapidly
after several seconds.
X Proceed with programming step 5 and
step 6 to complete.
i Upon 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.
Reprogramming a single signal
transmitter button To program a device using a signal
transmitter button previously trained, follow
these steps: X
Switch on the ignition.
X Press and hold the desired signal
transmitter button ( ;, = or ?). Do not
release the button.
Indicator lamp : will begin to flash after
20 seconds.
X Without releasing the signal transmitter
button,

proceed with programming starting
with step 3.
Operation of integrated remote control X
Switch on the ignition.
X Select and press the appropriate
integrated signal transmitter button ( ;,
=

or ?) 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 20 seconds.
Erasing the integrated remote control
memory i
If
you sell your vehicle, erase the codes of
all three channels.
X Switch on the ignition.
X Simultaneously press and hold outer signal
transmitter buttons ; and ?, for
approximately 20 seconds, until indicator
lamp : 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:
R
Check the frequency of hand-held remote

control is compatible with radio-frequency
devices operating between 280-390 MHz
.
R Put a new battery in hand-held remote
control A. This will increase the likelihood
of the hand-held remote control sending a
stronger and more accurate signal to the
integrated remote control.
R While performing step 3, hold hand-held
remote control A at different lengths and
angles from the signal transmitter button
(;, = or ?) you are programming.
Attempt varying angles at the distance of 2
to 12 inches (5 to 30 cm) away or the same
angle at varying distances.
R 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.
R Straighten the antenna wire from the
garage door opener assembly. This may
help improve transmitting and/or receiving
signals.
i Certain 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 Center, or call
the Mercedes-Benz Customer Assistance
Center (in the USA) at
1-800-FOR-MERCedes, or the HomeLink ®

G
Warning!
Whenever you are using floormats, make sure
there is enough clearance and that the
floormats are securely fastened.
Floormats should always be securely fastened
using the fastening equipment.
Before driving off, check that the floormats
are securely in place and adjust them if
necessary. A loose floormat could slip and
hinder proper functioning of the pedals.
Do not place several floormats on top of each
other as this may impair pedal movement.
X Move the driver’s seat or front passenger
seat as far to the rear as possible. X
Removing: Pull floormat off of retainer
pins :.
X Installing: Press floormat eyelets ; onto
retainer pins :. Infrared reflecting windshield
Infrared reflecting glass reduces the amount
of radiated heat entering the vehicle interior
through the windows.
The infrared reflecting glass also prevents the
transmission of signals through the glass by
in-vehicle electronic devices, e.g. electronic
toll collection devices. To allow the use of these devices in the
vehicle, infrared transparent areas
: are
placed in the windshield. Useful features

i This Operator’s Manual describes all
features, standard or optional, potentially
available for your vehicle at the time of
purchase. Please be aware that your
vehicle might not be equipped with all
features described in this manual. The first 1000 miles (1500 km)
The more cautiously you treat your vehicle
during
the break-in period, the more satisfied
you will be with its performance later on.
R Drive your vehicle during the first
1 000 miles (1 500 km) at varying but
moderate vehicle and engine speeds.
R During this period, avoid heavy loads (full
throttle driving) and excessive engine
speeds (no more than 2
/ 3 of maximum rpm
in each gear).
R Select C as the preferred shift program
(Y page 120) for the first 1 000 miles
(1 500 km).
R Avoid accelerating by kickdown.
R Do not attempt to slow the vehicle down by
shifting to a lower gear using the gear
selector lever.
R Select gear ranges 3, 2 or 1 (Y page 119)
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 the
rear differential have been replaced.

Refueling
G
Warning!
Gasoline and diesel fuels are highly flammable
and poisonous. They burn violently and can
cause serious injury.
Never allow sparks, flames or smoking
materials near gasoline or diesel fuel!
Turn off the engine before refueling.
Whenever you are around gasoline or diesel
fuel, avoid inhaling fumes and any skin or
clothing contact. Extinguish all smoking
materials.
Direct skin contact with fuels and the
inhalation of fuel vapors are damaging your
health. G
Warning!
Overfilling of the fuel tank may create
pressure in the system which could cause a
gas discharge. This could cause the gas to
spray

back out when removing the fuel pump
nozzle, which could cause personal injury. G
Warning!
Do not fill diesel tanks with gasoline. Do not
mix diesel fuel with gasoline. Otherwise the
fuel

system and engine could be damaged. In
addition, the vehicle could catch fire.
! Never use diesel fuel in vehicles with
gasoline engine. Never refuel vehicles with
gasoline engine with diesel fuel. Even small
amounts of incorrect fuel will damage the
fuel system and engine. Damage resulting
from the use of non-approved fuels or fuel
additives or resulting from mixing gasoline
with diesel fuel or vice versa is not covered
by the Mercedes-Benz Limited Warranty.
! If you have accidentally filled the tank
with incorrect or non-approved fuel, do not
switch on the ignition. Otherwise the
incorrect or non-approved fuel will get into
the fuel lines. The fuel system must be 220

Mercedes-Benz Center to have the fuel
system drained completely.
! Gasoline engine:
To prevent damage to the catalytic
converters, only use premium unleaded
gasoline in this vehicle.
Any noticeable irregularities in engine
operation should be repaired promptly.
Otherwise, excessive unburned fuel may
reach the catalytic converter, causing it to
overheat and potentially start a fire.
! Diesel engine:
When filling the diesel fuel tank using fuel
containers, place a filling filter, a suede
cloth or a clean flannel cloth as a filter.
Otherwise, particles from the fuel container
could clog the fuel lines and/or the diesel
injection system.

The engine is more susceptible to wear and
damage if you use
R marine diesel fuel
R heating oil
R additives
The exhaust aftertreatment device will be
seriously damaged if you use any other
diesel fuel than ULTRA-LOW SULFUR
HIGHWAY DIESEL FUEL (15 ppm SULFUR
MAXIMUM).
The use of such non-approved fuels and/or
special additives is not covered by the
Mercedes-Benz Limited Warranty.
i Gasoline engine:
