2010 MERCEDES-BENZ R320 gas type

Vehicle equipment
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.
i Always obey applicable speed limits. At the gas station
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

Snow chains
! Vehicles with Adaptive Damping System
(ADS):
When driving with snow chains, do not
select SPORT mode as this may result in
damage to your vehicle.
! Some tire sizes do not leave adequate
clearance for snow chains. To help avoid
serious damage to your vehicle or tires,
make sure the use of snow chains is
permissible as specified in the “Technical
data” section of this Operator’s Manual.
Snow chains should only be driven on snow-
covered roads at speeds not to exceed
30 mph (50 km/h)
. Remove chains as soon
as possible when driving on roads without
snow.
Observe the following guidelines when using
snow chains:
R Use of snow chains is not permissible with
all wheel/tire combinations ( Y page 347).
R Use snow chains in pairs and on rear
wheels only. Follow the manufacturer’s
mounting instructions.
! If snow chains are mounted to the front
wheels, they may scrape against the body
or axle components. The tires or the vehicle
could be damaged as a result.
R Only use snow chains that are approved by
Mercedes-Benz. Any authorized Mercedes-
Benz Center will be glad to advise you on
this subject.
R Use of snow chains may be prohibited
depending on location. Always check local
and state laws before installing snow
chains.
R Do not use snow chains on the spare wheel.
i When driving with snow chains, you may
wish to switch off the ESP ®
(Y page 65)
before setting the vehicle in motion. This
will improve the vehicle’s traction. Winter driving instructions
G
Warning!
If the vehicle becomes stuck in snow, make
sure snow is kept clear of the exhaust pipe
and from around the vehicle with the engine
running. Otherwise, deadly carbon monoxide
(CO) gases may enter vehicle interior
resulting in unconsciousness and death.
To

assure sufficient fresh air ventilation, open
a window slightly on the side of the vehicle
not facing the wind. G
Warning!
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Indicated temperatures just above the
freezing

point do not guarantee that the road
surface is free of ice. The road may still be icy,
especially in wooded areas or on bridges. G
Warning!
On slippery road surfaces, never downshift in
order to obtain braking action. This could
result

in drive wheel slip and reduced vehicle
control. Your vehicle’s ABS will not prevent
this type of loss of control.
The most important rule for slippery or icy
roads is to drive sensibly and to avoid abrupt
acceleration, braking and steering
maneuvers. Do not use the cruise control
system under such conditions.
When the vehicle is in danger of skidding, shift
the automatic transmission to neutral
position N. Try to keep the vehicle under
control by corrective steering action.
i For information on driving with snow
chains, see “Snow chains” ( Y page 252).
Road salts and chemicals can adversely
affect braking efficiency. Increased pedal
force may become necessary to produce the
normal brake effect.
Depressing the brake pedal periodically when
traveling at length on salt-strewn roads can 252
