Protection of the environment
General notes
H
Environmental note
Daimler's declared policy is one of
comprehensive environmental protection.
The objectives are for the natural resources
that form the basis of our existence on this
planet to be used sparingly and in a manner
that takes the requirements of both nature
and humanity into account.
You too can help to protect the environment
by operating your vehicle in an
environmentally responsible manner.
Fuel consumption and the rate of engine,
transmission, brake and tire wear are affected
by these factors:
R operating conditions of your vehicle
R your personal driving style
You can influence both factors. You should
bear the following in mind:
Operating conditions:
R avoid short trips as these increase fuel
consumption.
R always make sure that the tire pressures
are correct.
R do not carry any unnecessary weight.
R remove roof racks once you no longer need
them.
R a regularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
R always have service work carried out at a
qualified specialist workshop.
Personal driving style:
R do not depress the accelerator pedal when
starting the engine.
R do not warm up the engine when the vehicle
is stationary.
R drive carefully and maintain a safe distance
from the vehicle in front.
R avoid frequent, sudden acceleration and
braking. R
change gear in good time and use each gear
only up to 0001of its maximum engine speed.
R switch off the engine in stationary traffic.
R keep an eye on the vehicle's fuel
consumption. Environmental concerns and
recommendations
Wherever the operating instructions require
you to dispose of materials, first try to
regenerate or re-use them. Observe the
relevant environmental rules and regulations
when disposing of materials. In this way you
will help to protect the environment. Genuine Mercedes-Benz parts
H
Environmental note
Daimler AG also supplies reconditioned major
assemblies and parts which are of the same
quality as new parts. They are covered by the
same Limited Warranty entitlements as new
parts.
! Air bags and Emergency Tensioning
Devices, as well as control units and
sensors for these restraint systems, may be
installed in the following areas of your
vehicle:
R doors
R door pillars
R door sills
R seats
R cockpit
R instrument cluster
R center console
Do not install accessories such as audio
systems in these areas. Do not carry out
repairs or welding. You could impair the
operating efficiency of the restraint
systems. Introduction

WARNING
This Sport Utility Vehicle is designed for both
on-road and off-road use. It can go places and perform tasks for which conventional 2-wheel
drive passenger cars are not intended. This
vehicle will handle and maneuver differently
from conventional passenger cars in driving
conditions which may occur on streets,
highways and off-road use.
This vehicle has a higher ground clearance
and a higher center of gravity than many
passenger cars. As with other vehicles of this
type, if you make sharp turns at excessive
speeds or abrupt maneuvers, the vehicle may
roll over or may go out of control and crash.
Utility vehicles have a significantly higher
rollover rate than other types of vehicles.
Failure to operate this vehicle safely may
result in an accident, rollover of the vehicle,
and severe or fatal injury.
Before you start to drive this vehicle, read the
Operator's Manual. Take time to become
familiar with the driving characteristics of this
vehicle. Be sure you are familiar with all
vehicle controls. Learn how your vehicle
handles on different road surfaces. Do not
attempt sharp turns at excessive speeds or
abrupt maneuvers or other unsafe driving
actions that can cause loss of vehicle control.
When driving off-road or working the vehicle
hard, do not overload it. And, always wear
your seat belts at all times. In a rollover crash,
an unbelted person is significantly more likely
to die than a person wearing a seat belt.

SRS (Supplemental Restraint System)
Introduction SRS consists of:
R
001F SRS warning lamp
R Air bags
R The air bag control unit with crash sensors
R Emergency Tensioning Devices for the
front seat belts and the outer seat belts in
the rear
R Belt force limiters
SRS reduces the risk of occupants coming
into contact with the vehicle's interior in the
event of an accident. It can also reduce the
effect of the forces to which occupants are
subjected during an accident.
SRS warning lamp G
WARNING
The SRS self-chec khas detected a
malfunction if the 001FSRS indicator lamp:
R does no tlight up at all
R does not go out after approximately four
seconds after the engine is started
R lights up after the engin eis started or while
the vehicle is in motion
For your safety, Mercedes-Benz strongly
recommends that you have the system
checked as soon as possible at a qualified
specialist workshop. SRS may otherwise fail
to activate when it is needed in the event of
an accident, which could lead to serious or
fatal injuries. SRS might also be activated
unexpectedly and unnecessarily, which could
also result in injury.
In addition, work carried out improperly on
SRS may render SRS inoperative or cause
unintended air bag deployment. Work on the
SRS system should only be carried out by
qualified specialist personnel. Consult a
qualified specialist workshop.
If it is necessary to modify an air bag system
to accommodate a person with disabilities,
contact an authorized Mercedes-Benz Center for details. USA only: for further information,
contact our Customer Assistance Center at
1-800-FOR-MERCedes (1-800-367-6372).
SRS functions are checked regularly when
you switch on the ignition and when the
engine is running. Therefore, malfunctions
can be detected in good time.
The 001F SRS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out no later than a few seconds
after the engine is started.
The SRS components are in operational
readiness when the 001FSRS warning lamp
goes out while the engine is running.

month-old child seated in astandard child
restraint or as being a small individual (such
as a young teenager or asmall adult), the
001A001C indicator lamp will illuminate for
approximately 6seconds when the engine is

WARNING
According to accident statistics, children are
safer when properly restrained on the rear
seats than on the front-passenger seat. Thus,
we strongly recommend that children be
placed in the rear seats whenever possible.
Regardless of seating position, children 12
years old and under must be seated and
properly secured in an appropriate infant
restraint, toddler restraint, or booster seat
recommended for the size and weight of the
child.
The infant or child restraint must be properly
secured with the vehicle's seat belt, the seat
belt and Top Tether strap, or lower anchors
and Top Tether strap, fully in accordance with
the child seat manufacturer's instructions.
Occupants, especially children, should always
sit as upright as possible, wear the seat belt
properly and use an appropriately sized infant
restraint, toddler restraint, or booster seat
recommended for the size and weight of the
child. Occupant safety

Belt warning for the driver and front
passenger Regardless of whether the driver's and front-
passenger seat belts have already been
fastened, the
0020seat belt warning lamp lights up for six seconds each time the engine
is started. It then goes out if the driver and
the front passenger have already fastened
their seat belts.
If the driver's seat belt is not fastened when
the engine is started, an additional warning
tone will sound. This warning tone stops after
a maximum of six seconds or once the
driver's seat belt is fastened.
If after six seconds, the driver or front
passenger have not fastened their seat belts
and the doors are closed:
R the 0020 seat belt warning lamp remains lit
as long as the driver's or front-passenger's
seat belt is not fastened
and
R if a vehicle speed of 15 mph (25 km/h) is
exceeded, the 0020seat belt warning lamp
begins to flash. Awarning tone also sounds
with increasing intensity for a maximum of
60 seconds or until the driver or front
passenger have fastened their seat belts.
If the driver/front passenger unfasten their
seat belt while the vehicle is in motion, the
0020 seat belt warning lamp lights up and a
warning tone sounds again.
The warning tone ceases eve nifthe driver or
front-passenger seat belt has still not been
