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 00C3of its maximum engine speed.
R switch off the engine in stationary traffic.
R keep an eye on the vehicle's fuel
consumption. 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.
Have aftermarket accessories installed at
a qualified specialist workshop.
You could jeopardize the operating safety of
your vehicle if you use parts, tires and wheels
as well as accessories relevant to safety
which have not been approved by Mercedes.
This could lead to malfunctions in safety-
relevant systems, e.g. the brake system. Use
only genuine Mercedes-Benz parts or parts of
equal quality. Only use tires, wheels and 20
Introduction

accessories that have been specifically
approved for your vehicle.
Genuine Mercedes-Benz parts are subject to
strict quality control. Every part has been
specifically developed, manufactured or
selected for and adapted to Mercedes-Benz
vehicles. Only genuine Mercedes-Benz parts
should therefore be used.
More than 300,000 different genuine
Mercedes-Benz parts are available for
Mercedes-Benz models.
All authorized Mercedes-Benz Centers
maintain a supply of genuine Mercedes-Benz
parts for necessary service and repair work.
In addition, strategically located parts
delivery centers provide quick and reliable
parts service.
Always specify the vehicle identification
number (VIN) when ordering genuine
Mercedes-Benz parts (Y page 342).Operator's Manual

98 Vanderhoof Avenue
Toronto, Ontario M4G 4C9 Sports Utility Vehicle
G
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. Operating safety

repairs carried out at a qualified specialist
workshop. G
