2007 Mercedes-benz G Class Owners Manual

For example, a load rating of 91 corre- sponds to a maximum load of 1356 lbs (615 kg) the tire is designed to support. See also “Maximum tire load” (컄 page 300) where the maximum load associated with the load index is indicated in kilograms and lbs.

Warning!

The tire load rating must always be at least half of the GAWR (컄 page 305) of your vehicle. Otherwise, tire failure may be the result which may cause an accident and/or serious personal injury to you or others.

Always replace rims and tires with the same designation, manufacturer and type as shown on the original part.

Warning!

Do not overload the tires by exceeding the specified load limit as indicated on the Tire and Loading Information placard located on the driver’s door B-pillar. Overloading the tires can overheat them, possibly causing a blowout. Overloading the tires can also result in handling or steering problems, or brake failure.

i Tire load rating 5 (컄 page 295) and tire speed rating 6 (컄 page 295) are also referred to as “service description”.

Tire speed rating The tire speed rating 6 (컄 page 295) indicates the approved maximum speed for the tire.

Warning!

Even when permitted by law, never operate a vehicle at speeds greater than the maximum speed rating of the tires.

Exceeding the maximum speed for which tires are rated can lead to sudden tire failure, causing loss of vehicle control and possibly resulting in an accident and/or personal injury and possible death, for you and for others.

Operation Tires and wheels

앫 At the tire manufacturer’s option, any

tire with a speed capability above 149 mph (240 km/h) can include a “ZR” in the size designation (for exam- ple: 245/40 ZR18). To determine the maximum speed capability of the tire, the service description for the tire must be referred to. The service description is comprised of the tire load rating 5 (컄 page 295) and the tire speed rating 6 (컄 page 295). If your tire includes “ZR” in the size designation and no service description 5 and 6 (컄 page 295) is given, the tire manufacturer must be consulted for the maximum speed capability.

In addition to tire load rating, special load identification 1 may be molded into the tire sidewall following the letter designat- ing the tire speed rating (컄 page 295). No specification given: absence of any text (like in above example) indicates a standard load (SL) tire. XL or Extra Load: designates an extra load (or reinforced) tire. Light Load: designates a light load tire. C, D, E: designates load range associated with the maximum load a tire can carry at a specified pressure.

DOT, Tire Identification Number (TIN)

U.S. tire regulations require each new tire manufacturer or tire retreader to mold a TIN into or onto a sidewall of each tire produced. The TIN is a unique identifier which facili- tates efforts by tire manufactures to notify purchasers in recall situations or other safety matters concerning tires and gives purchasers the means to easily identify such tires. The TIN is comprised of “Manufacturer’s identification mark”, “Tire size”, “Tire type code” and “Date of manufacture”.

1 Maximum permissible tire inflation

pressure

i For illustration purposes only. Actual data on tires are specific to each vehicle and may vary from data shown in above illustration.

This is the maximum permissible tire inflation pressure for the tire.

Operation Tires and wheels

Always follow the recommended tire inflation pressure (컄 page 286) for proper tire inflation.

Warning!

Never exceed the max. tire inflation pressure. Follow recommended tire inflation pressures.

Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely affect handling and fuel economy, and are more likely to fail from being over- heated.

Do not overinflate tires. Overinflated tires can adversely affect handling and ride comfort, wear unevenly, increase stopping distance, and result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road debris, potholes etc.

301

Quality grades can be found, where applicable, on the tire sidewall between tread shoulder and maximum section width. For example:

Treadwear Traction Temperature 200

AA

All passenger car tires must conform to federal safety requirements in addition to these grades.

Treadwear The treadwear grade is a comparative rat- ing based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and one-half (1 1/2) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate.

Operation Tires and wheels

Uniform Tire Quality Grading Standards (U.S. vehicles)

Tire manufacturers are required to grade tires based on three performance factors: treadwear, traction and temperature resistance.

1 Treadwear 2 Traction 3 Temperature resistance

i For illustration purposes only. Actual data on tires are specific to each vehicle and may vary from data shown in above illustration.

302

Traction The traction grades, from highest to lowest, are AA, A, B, and C. Those grades represent the tire’s ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction perfor- mance.

Warning!

The traction grade assigned to this tire is based on straight-ahead braking traction tests, and does not include acceleration, cornering, hydroplaning, or peak traction characteristics.

Temperature The temperature grades are A (the high- est), B, and C, representing the tire’s resis- tance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high tem- perature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law.

Operation Tires and wheels

Warning!

The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause excessive heat build-up and possible tire failure.

Operation Tires and wheels

Rotating tires

Warning!

Rotate front and rear wheels only if the tires are of the same dimension.

If your vehicle is equipped with mixed-size tires (different tire dimensions front vs. rear), tire rotation is not possible.

Tire rotation can be performed on vehicles with tires of the same dimension all around. If your vehicle is equipped with tires of the same dimension all around, tires can be rotated, observing a front-to-rear rotation pattern that will maintain the intended rotation (spinning) direction of the tire (컄 page 280). In some cases, such as when your vehicle is equipped with mixed-size tires (different tire dimension front vs. rear), tire rotation is not possible.

307

Warning!

Have the tightening torque checked after changing a wheel. Wheels could become loose if not tightened with a torque of 97 lb-ft (130 Nm).

Only use genuine Mercedes-Benz wheel bolts specified for your vehicle’s rims.

For information on wheel change, see the “Practical hints” section (컄 page 366) and (컄 page 390).

Operation Tires and wheels

If applicable to your vehicle’s tire confi- guration, tires can be rotated according to the tire manufacturer’s recommended intervals in the tire manufacturer’s warranty pamphlet located in your vehicle literature portfolio. If none is available, tires should be rotated every 3000 to 6000 miles (5000 to 10000 km), or sooner if necessary, according to the degree of tire wear. The same rotation (spinning) direction must be maintained (컄 page 280). Rotate tires before the characteristic tire wear pattern becomes visible (shoulder wear on front tires and tread center wear on rear tires). Thoroughly clean the mounting face of wheels and brake disks, i.e. the inner side of the wheels/tires, during each rotation. Check for and ensure proper tire inflation pressure.

308

왔 Winter driving Before the onset of winter, have your vehicle winterized at an authorized Mercedes-Benz Light Truck Center. This service includes: 앫 Check of anticorrosion and antifreeze

concentration.

앫 Addition of cleaning concentrate to the water of the windshield and headlamp cleaning system. Add MB Concentrate “MB SummerFit” to a premixed wind- shield washer solvent/antifreeze which is formulated for below freezing temperatures (컄 page 430).

앫 Battery test. Battery capacity drops

with decreasing ambient temperature. A well charged battery helps to make sure that the engine can be started, even at low ambient temperatures. 앫 Tire change. Mercedes-Benz recom-

mends M+S rated radial-ply tires with a minimum tread depth of approximately 1/6 in (4 mm) on all four wheels for the winter season.

Winter tires

Always use winter tires at temperatures below 45°F (7°C) and whenever wintry road conditions prevail. Not all M+S rated tires provide special winter performance. Make sure the tires you use show M+S and the mountain/snowflake marking . on the tire sidewall. These tires meet specific snow traction performance requirements of the Rubber Manufacturers Association (RMA) and the Rubber Association of Canada (RAC) and have been designed specifically for use in snow conditions. Using winter tires is the only way to achieve the maximum effectiveness of the ABS, ESP® and 4-ETS in winter operation. For safe handling, make sure all mounted winter tires are of the same make and have the same tread design.

Operation Winter driving

Warning!

Winter tires with a tread depth of less than 1/6 in (4 mm) must be replaced. They are no longer suitable for winter operation.

Always observe the speed rating of the winter tires installed on your vehicle. If the maximum speed for which your tires are rated is below the speed rating of your vehicle, you must place a notice to this effect where it will be seen by the driver. Such notices are available from your tire dealer or from any authorized Mercedes-Benz Light Truck Center.

309

Operation Winter driving

Warning!

Block heater (Canada only)

If you use your spare tire when winter tires are fitted on the other wheels, be aware that the difference in tire characteristics may very well impair turning stability and that overall driving stability may be reduced. Adapt your driving style accordingly.

Have the spare tire replaced with a winter tire at the nearest authorized Mercedes-Benz Light Truck Center.

The engine is equipped with a block heater. The electrical cable may be installed at an authorized Mercedes-Benz Light Truck Center.

Snow chains

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.

i When driving with snow chains, you may wish to deactivate the ESP® (컄 page 92) before setting the vehicle in motion. This will improve the vehicle’s traction.

Please observe the following guidelines when using snow chains: 앫 Use of snow chains is not permissible

with all wheel/tire combinations (컄 page 417).

앫 Snow chains should only be used on the rear wheels. Follow the manufac- turer’s mounting instructions. 앫 Only use snow chains that are

approved by Mercedes-Benz. Any authorized Mercedes-Benz Light Truck Center will be glad to advise you on this subject.

앫 Use of snow chains may be prohibited depending on location. Always check local and state laws before installing snow chains.

Operation Vehicle care

Cleaning and care of the vehicle

Regular and proper care will help to main- tain the value of your vehicle. The best way to protect your vehicle from harmful envi- ronmental influences is to wash it and use protective treatments regularly.

Warning!

Many cleaning products can be hazardous. Some are poisonous, others are flammable. Always follow the instructions on the partic- ular container. Always open your vehicle’s doors or windows when cleaning the inside.

Never use fluids or solvents that are not designed for cleaning your vehicle.

Always lock away cleaning products and keep them out of reach of children.

314

While in operation, even while parked, your vehicle is subjected to varying external influences which, if gone unchecked, can attack the paintwork as well as the under- body and cause lasting damage. Such damage is caused not only by extreme and varying climatic conditions, but also by: 앫 Air pollution 앫 Road salt 앫 Tar 앫 Gravel and stone chipping

To avoid paint damage, you should imme- diately remove: 앫 Grease and oil 앫 Fuel 앫 Coolant 앫 Brake fluid 앫 Bird droppings 앫 Insects 앫 Tree resins, etc. Frequent washing reduces and/or eliminates the aggressiveness and potency of the above adverse influences. More frequent washings are necessary to deal with unfavorable conditions: 앫 near the ocean 앫 in industrial areas (smoke, exhaust

emissions)

앫 during winter operation

Operation Vehicle care

You should check your vehicle from time to time for stone chipping or other damage. Any damage should be repaired as soon as possible to prevent corrosion. In doing so, do not neglect the underbody of the vehicle. A prerequisite for a thor- ough check is a washing of the underbody followed by a thorough inspection. Dam- aged areas need to be re-undercoated. Your vehicle has been treated at the factory with a wax-base rustproofing in the body cavities which will last for the lifetime of the vehicle. Post-production treatment is neither necessary nor recommended by Mercedes-Benz because of the possibility of incompatibility between materials used in the production process and others applied later.

We have selected car-care products and compiled recommendations which are specially matched to our vehicles and which always reflect the latest technology. You can obtain Mercedes-Benz approved car-care products at an authorized Mercedes-Benz Light Truck Center. Scratches, corrosive deposits, corrosion or damage due to negligent or incorrect care cannot always be removed or repaired with the car-care products recommended here. In such cases it is best to seek aid at an authorized Mercedes-Benz Light Truck Center. The following topics deal with the cleaning and care of your vehicle and give important “how-to” information as well as references to Mercedes-Benz approved car-care products.

Power washer

! Follow the instructions provided by the power washer manufacturer on maintaining a distance between the vehicle and the nozzle of the power washer. Never use a round nozzle to power-wash tires. The intense jet of water can result in damage to the tire. Always replace a damaged tire. Always keep the jet of water moving across the surface. Do not aim directly at electrical parts, electrical connectors, sensors, seals, or other rubber parts.

Tar stains Quickly remove tar stains before they dry and become more difficult to remove. A tar remover is recommended.

315

Operation Vehicle care

Paintwork, painted body components

! Affixing stickers, adhesive tape or similar materials to painted body components may damage the paintwork.

Mercedes-Benz approved Paint Care should be applied when water drops on the paint surface do not “bead up”. This should normally be done every 3 to 5 months, depending on the climate and washing detergent used. Mercedes-Benz approved Paint Cleaner should be applied if the paint surface shows signs of dirt embedding (i.e. loss of gloss). Do not apply any of these products or wax if your vehicle is parked in the sun or if the hood is still hot. 왘 Use the appropriate MB-Touch-Up

Stick for quick and provisional repairs of minor paint damage (i.e. chips from stones, vehicle doors, etc.).

316

Engine cleaning Prior to cleaning the engine compartment, make sure to protect electrical compo- nents and connectors from the intrusion of water and cleaning agents. Corrosion protection, such as MB Anticorrosion Wax, should be applied to the engine compartment after every engine cleaning. Before applying, all con- trol linkage bushings and joints should be lubricated. The poly-V-belt and all pulleys should be protected from any wax.

Vehicle washing In the winter, thoroughly remove all traces of road salt as soon as possible. When washing the vehicle underbody, do not forget to clean the inner sides of the wheels.

Hand-wash Do not use hot water or wash your vehicle in direct sunlight. 왘 Only use a mild car wash detergent,

such as Mercedes-Benz approved Car Shampoo.

왘 Thoroughly spray the vehicle with a

diffused jet of water. Direct only a very weak spray towards the ventilation intake.

왘 Use plenty of water and rinse the

sponge and chamois frequently.

왘 Rinse with clean water and thoroughly

dry with a chamois. Do not allow cleaning agents to dry on the finish.

! Do not use scouring agents on these parts. Never apply strong force and only use a soft, non-scratching cloth when cleaning the vehicle. Do not attempt to wipe the surface with a dry cloth or sponge. Otherwise you may scratch or damage the paint.

Automatic car wash You can have your car washed in an auto- matic car wash from the start. Automatic car washes without brushes are prefera- ble. 왘 To protect the filter system, switch the

climate control to air recirculation mode (컄 page 183).

! Do not clean your vehicle in an automatic touchless car wash which use caustic spray. Otherwise the caustic spray will damage the paint or ornamental moldings.

If the vehicle is very dirty, prewash it before running it through the automatic car wash.

! Make sure that the windshield wiper switch is set to 0 (컄 page 58). Otherwise, e.g. the rain sensor could activate and cause the wipers to move unintentionally. This may lead to vehicle damage. Due to the width of the vehicle, fold in exterior rear view mirrors prior to running the vehicle through an automatic car wash to prevent damage to the mirrors.

i After running the vehicle through an auto- matic car wash, wipe any wax off of the wind- shield (컄 page 319). This will prevent smears and reduce wiping noise which can be caused by residual wax on the windshield. When leaving the car wash, make sure that the mirrors are folded out. Otherwise they may vibrate.

Operation Vehicle care

Ornamental moldings For regular cleaning and care of ornamental moldings, use a damp cloth.

! Do not use chrome cleaner on ornamental moldings. Although ornamental moldings may have chrome appearance, they could be made of anodized aluminum that will be damaged when cleaned with chrome cleaner. Instead, use a damp cloth to clean those ornamental moldings. For very dirty ornamental moldings of which you are sure are chrome-plated, use a chrome cleaner. If in doubt whether an ornamental molding is chrome-plated, contact an authorized Mercedes-Benz Light Truck Center.

317

Cleaning the Rear Parking Assist sensors

! Do not apply strong pressure to the sensor covers. Applying strong pressure may damage the sensor covers. Follow the instructions provided by the power washer manufacturer on maintaining a distance between the vehicle and the nozzle of the power washer.

왘 Have the Advanced TPMS checked at

an authorized Mercedes-Benz Light Truck Center.

After the malfunction has been remedied the combination low tire pressure/TPMS malfunction telltale goes out after few minutes driving.

335

Practical hints What to do if …

Warning!

Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recom- mended by the vehicle manufacturer on the Tire and Loading Information placard on the driver’s door B-pillar or, if available, the tire inflation pressure label on the inside of the fuel filler flap. If your vehicle has tires of a different size than the size indicated on the Tire and Loading Information placard or the tire inflation pressure label, you should determine the proper tire inflation pressure for those tires. As an added safety feature, your vehicle has been equipped with a Advanced Tire Pres- sure Monitoring System (Advanced TPMS) that illuminates a low tire pressure telltale when one or more of your tires is signifi- cantly underinflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure.

336

When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended.

Advanced TPMS malfunctions may occur for a variety of reasons, including the installa- tion of replacement or alternate tires or wheels on the vehicle that prevent the Ad- vanced TPMS from functioning properly. Al- ways check the Advanced TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to en- sure that the replacement or alternate tires and wheels allow the Advanced TPMS to continue to function properly.

Driving on a significantly underinflated tire causes the tire to overheat and can lead to tire failure.

Underinflation also reduces fuel efficiency and tire tread life, and may affect the vehi- cle’s handling and stopping ability. Please note that the Advanced TPMS is not a sub- stitute for proper tire maintenance, and it is the driver’s responsibility to maintain cor- rect tire pressure, even if underinflation has not reached the level to trigger illumination of the Advanced TPMS low tire pressure tell- tale.

USA only: Your vehicle has also been equipped with a Advanced TPMS malfunc- tion indicator to indicate when the system is not operating properly. The Advanced TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately 1 minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists.
