Product information

Kindly observe the following in your own best interest:

We recommend using Mercedes-Benz original parts as well as conversion parts and accessories
explicitly approved by us for your vehicle model.

We have tested these parts to determine their reliability, safety and their special
suitability for Mercedes-Benz vehicles.

We are unable to make an assessment for other products and therefore cannot be held responsible
for them, even if in individual cases an official approval or authorization by governmental or other
agencies should exist. Use of such parts and accessories could adversely affect the safety,
performance or reliability of your vehicle. Please do not use them.

Mercedes-Benz original parts as well as conversion parts and accessories approved by us are available

Operator’s manual

This Operator’s Manual contains a great deal of useful information. We urge you to read it carefully and familiarize
yourself with the vehicle before driving.

For your own safety and longer service life of the vehicle, we urge you to follow the instructions and warnings
contained in this manual. Ignoring them could result in damage to the vehicle or personal injury to you or others.
Vehicle damage caused by failure to follow instructions is not covered by the Mercedes-Benz Limited Warranty.

Your vehicle may have some or all of the equipment described in this manual. Therefore, you may find explanations
for optional equipment not installed in your vehicle. If you have any questions about the operation of any equipment,
your authorized Mercedes-Benz Light Truck Center will be glad to demonstrate the proper procedures.

Service and warranty information

The Service and Warranty Information Booklet contains detailed information about the warranties covering your
Mercedes-Benz, including:

• New Light Truck Limited Warranty,

• Emission System Warranty,

• Emission Performance Warranty,

• California, Maine, Massachusetts, and Vermont Emission Control System Warranty

(California, Maine, Massachusetts, and Vermont only),

• State Warranty Enforcement Laws (Lemon Laws).

Important notice for California retail buyers of Mercedes-Benz automobiles

Under California law you may be entitled to a replacement of your vehicle or a refund of the purchase price, if
Mercedes-Benz USA, LLC or its authorized Mercedes-Benz Center fails to conform the vehicle to its express warranties
after a reasonable number of repair attempts during the period of one year or 12 000 miles from original delivery of
the vehicle. A reasonable number of repair attempts is presumed for a retail buyer (1) if the vehicle is out of service by
reason of repair of substantial nonconformities for a cumulative total of more than 30 calendar days or (2) the same
substantial non-conformity has been subject to repair four or more times and you have at least once directly

notified us in writing of the need to repair the non-conformity and have given us an opportunity to perform the
repair ourselves. Notifications should be sent to the nearest Mercedes-Benz Regional Office listed in the
Service and Warranty Information Booklet.

Maintenance

The Service Booklet describes all the necessary maintenance work which should be performed at regular intervals.

Always have the Service Booklet with you when you take the vehicle to your authorized Mercedes-Benz Light Truck
Center for service. The service advisor will record each service in the booklet for you.

Roadside assistance

The Mercedes-Benz Roadside Assistance Program provides factory trained technical help in the event of a breakdown.
Calls to the toll-free Roadside Assistance number:

1-800-FOR-MERCedes (in the USA)
1-800-387-0100 (in Canada)

will be answered by Mercedes-Benz Client Assistance Representatives 24 hours a day, 365 days a year.

Roadside assistance will be provided in accordance with standard program guidelines which include providing service
to the vehicle up to a reasonable distance from a paved roadway. We will make every effort to assist in a breakdown
situation, however, the accessibility of your vehicle will be determined by our authorized Mercedes-Benz Light Truck
Center technician or the tow service provider on a case by case basis and may be a factor in our ability to respond.

Additional charges may be applicable for a breakdown location determined not to be a reasonably accessible roadside
location as determined by our authorized technician and tow service provider.

For additional information refer to the Mercedes-Benz Roadside Assistance Program brochure in your glove box.

Change of address or ownership

If you change your address, be sure to send in the “Change of Address Notice” found in the Service and Warranty
Information Booklet, or simply call the Mercedes-Benz Client Assistance Center (in the USA) at
1-800-FOR-MERCedes, or Customer Service (in Canada) at 1-800-387-0100. It is in your own interest that we can
contact you should the need arise.

If you sell your Mercedes, please leave all literature with the vehicle to make it available to the next operator.

If you bought this vehicle used, be sure to send in the “Notice of Purchase of Used Car” found in the Service and
Warranty Information Booklet, or call the Mercedes-Benz Client Assistance Center (in the USA) at
1-800-FOR-MERCedes, or Customer Service (in Canada) at 1-800-387-0100.

Operating your vehicle outside the USA or Canada

If you plan to operate your vehicle in foreign countries, please be aware that:

• Service facilities or replacement parts may not be readily available,

• unleaded gasoline for vehicles with catalytic converters may not be available; the use of leaded fuels will damage

the catalysts,

• gasoline may have a considerably lower octane rating, and improper fuel can cause engine damage.

12Introduction

We continuously strive to improve our product, and ask for your understanding that we reserve the right to make
changes in design and equipment. Therefore, information, illustrations and descriptions in this Operator’s Manual
might differ from your vehicle.

Optional equipment is also described in this manual, including operating instructions wherever necessary. Since they
are special-order items, the descriptions and illustrations herein may vary slightly from the actual equipment of your
vehicle.

If there are any equipment details that are not shown or described in this Operator’s Manual, your authorized
Mercedes-Benz Light Truck Center will be glad to inform you of correct care and operating procedures.

The Operator’s Manual and Service Booklet are important documents and should be kept with the vehicle.

War ning!

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 were 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, 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.

Explanation of color used:

Warning notices for the protection of yourself and
others appear on red background.

Problems with your vehicle

If you should experience a problem with your vehicle, particularly one that you believe may affect
its safe operation, we urge you to immediately contact your authorized Mercedes-Benz Light Truck
Center to have the problem diagnosed and corrected if required. If the matter is not handled to

death, you should immediately inform the National Highway Traffic Safety Administration
(NHTSA) in addition to notifying Mercedes-Benz USA, LLC.

If NHTSA receives similar complaints, it may open an investigation, and if it finds that a safety
defect exists in a group of vehicles, it may order a recall and remedy campaign. However, NHTSA
cannot become involved in individual problems between you, your retailer, or
Mercedes-Benz USA, LLC.

To contact NHTSA, you may either call the Auto Safety Hotline toll-free at 1-800-424-9393

Vehicl e keys

Included with your vehicle are:

• 2 remote controls with folding master keys,

• 1 reserve key,

War ning!

When leaving the vehicle always remove the key
from the steering lock, and lock your vehicle. Do
not leave children unattended in the vehicle, or
with access to an unlocked vehicle. Unsupervised
use of vehicle equipment may cause serious
personal injury.

Remote control with folding master key

The remote control operates all locks on the vehicle.

To release the key, press button (1). The key unfolds

The transmitter for the remote control is located in the
key ho lder.

Reserve key

The reserve key fits all locks on the vehicle.

For notes on the mechanical keys refer to page 29.

Note:

We recommend that you carry the reserve key with you
and keep it in a safe place (e.g. your wallet) so that it is
always handy. Never leave the reserve key in the
vehicle.

Obtaining replacement keys

Your vehicle is equipped with a theft deterrent locking
system requiring a special key manufacturing process.
For security reasons, replacement keys can only be
obtained from your authorized Mercedes-Benz Light
Truck Center.

Start lock-out

Important!

Removing the key from the steering lock activates the
start lock-out. The engine cannot be started.

Turning the key in the steering lock to position 2
deactivates the start lock-out.

Note:

In case the engine cannot be started and the
messages Á and î are shown in the odometer
