During all seasons, add MB Windshield Washer Concentrate “MB SummerFit” to water. Premix the windshield washer fluid in a suitable container.

! Always use washer solvent/antifreeze where temperatures may fall below freezing point. Failure to do so could result in damage to the washer system/reservoir.

Warning!

! Only use washer fluid which is suitable for plastic lenses. Improper washer fluid can dam- age the plastic lenses of the headlamps.

Washer solvent/antifreeze is highly flamma- ble. Do not spill washer solvent/ antifreeze on hot engine parts, because it may ignite and burn. You could be seriously burned.

For more information, see “Windshield and headlamp washer fluid mixing ratio” (컄 page 500).

왘 Use the tab to pull cap 1 upwards. 왘 Refill the reservoir with MB Windshield

Washer Concentrate and water (or commercially available premixed wind- shield washer solvent/antifreeze, de- pending on ambient temperatures).

왔 Tires and wheels See an authorized Mercedes-Benz Center for information on tested and recommend- ed rims and tires for summer and winter operation. They can also offer advice con- cerning tire service and purchase.

Warning!

Replace rims or tires with the same designa- tion, manufacturer and type as shown on the original part. See an authorized Mercedes-Benz Center for further informa- tion. If incorrectly sized rims and tires are mounted: 앫 The wheel brakes or suspension compo-

nents can be damaged

앫 The correct operating clearance of the wheels and the tires are no longer guar- anteed

Warning!

Worn, old tires can cause accidents. If the tire tread is badly worn, or if the tires have sustained damage, replace them.

When replacing rims, only use Genuine Mercedes-Benz wheel bolts specified for the particular rim type. Failure to do so can re- sult in the bolts loosening and possibly an accident.

Retreaded tires are not tested or recom- mended by Mercedes-Benz, since previous damage cannot always be recognized on re- treads. The operating safety of the vehicle cannot be assured when such tires are used.

Operation Tires and wheels

Important guidelines

앫 Only use sets of tires and rims of the

same type and make.

앫 Tires must be of the correct size for the

rim.

앫 Break in new tires for approximately

60 miles (100 km) at moderate speeds.

앫 Regularly check the tires and rims for

damage. Dented or bent rims can cause tire inflation pressure loss and damage to the tire beads.

앫 If vehicle is heavily loaded, check tire

inflation pressure and correct as required.

앫 Do not allow your tires to wear down too far. Adhesion properties on wet roads are sharply reduced at tread depths of less than 1/8 in (3 mm).

앫 When replacing individual tires, you should mount new tires on the front wheels first (on vehicles with same-sized wheels all around).

333

Tire inspection Every time you check your tire inflation pressure, you should also inspect your tires for the following: 앫 excessive treadwear (컄 page 335) 앫 cord or fabric showing through the

tire’s rubber

Life of tire The service life of a tire is dependent upon varying factors including but not limited to: 앫 Driving style 앫 Tire inflation pressure 앫 Distance driven

앫 bumps, bulges, cuts, cracks or splits in

the tread or side of the tire

Warning!

Tires and spare tire should be replaced after 6 years, regardless of the remaining tread.

Replace the tire if you find any of the above conditions. Make sure you also inspect the spare tire periodically for condition and inflation. Spare tires will age and become worn over time even if never used, and thus should be inspected and replaced when necessary.

Operation Tires and wheels

Tire care and maintenance

Warning!

Regularly check the tires for damage. Dam- aged tires can cause tire inflation pressure loss. As a result, you could lose control of your vehicle.

Worn, old tires can cause accidents. If the tire tread is badly worn, or if the tires have sustained damage, replace them.

Regularly check your tire inflation pressure at least once a month. For more informa- tion on checking tire inflation pressure, see “Recommended tire inflation pres- sure” (컄 page 341).

334

Tread depth Do not allow your tires to wear down too far. Adhesion properties on wet roads are sharply reduced at tread depths of less than 1/8 in (3 mm). Treadwear indicators (TWI) are required by law. These indicators are located in six places on the tread circumference and become visible at a tread depth of approx- imately 1/16 in (1.6 mm), at which point the tire is considered worn and should be re- placed. Recommended minimum tire tread depth: 앫 Summer tires 1/8 in (3 mm) 앫 Winter tires 1/6 in (4 mm)

Warning!

Although the applicable federal motor safety laws consider a tire to be worn when the treadwear indicators (TWI) become visible at approximately 1/16 in (1.6 mm), we recom- mend that you do not allow your tires

to wear down to that level. As tread depth approaches 1/8 in (3 mm), the adhesion properties on a wet road are sharply re- duced.

Depending upon the weather and/or road surface (conditions), the tire traction varies widely.

Operation Tires and wheels

Storing tires

! Keep unmounted tires in a cool, dry place with as little exposure to light as possible. Pro- tect tires from contact with oil, grease and gaso- line.

Cleaning tires

! Never use a round nozzle to power wash tires. The intense jet of water can result in dam- age to the tire. Always replace a damaged tire.

1 TWI (Tread Wear Indicator) The treadwear indicator appears as a solid band across the tread.

Operation Tires and wheels

Direction of rotation

Loading the vehicle

Unidirectional tires offer added advan- tages, such as better hydroplaning perfor- mance. To benefit, however, you must make sure the tires rotate in the direction specified. An arrow on the sidewall indicates the intended direction of rotation (spinning) of the tire.

i Spare wheels may be mounted against the direction of rotation (spinning) even with a unidi- rectional tire for temporary use only until the reg- ular drive wheel has been repaired or replaced. Always observe and follow applicable temporary use restrictions and speed limitations indicated on the spare wheel.

Two labels on your vehicle show how much weight it may properly carry. 1) The Tire and Loading Information

placard can be found on the driver’s door B-pillar. This placard tells you im- portant information about the number of people that can be in the vehicle and the total weight that can be carried in the vehicle. It also contains information on the proper size and recommended tire inflation pressures for the original equipment tires on your vehicle.

2) The certification label, also found on

the driver’s door B-pillar tells you about the gross weight capacity of your vehi- cle, called the Gross Vehicle Weight Rating (GVWR). The GVWR includes the weight of the vehicle, all occupants, fuel and cargo. The certification label also tells you about the front and rear axle weight capacity, called the Gross Axle Weight Rating (GAWR).

336

The GAWR is the total allowable weight that can be carried by a single axle (front or rear). Never exceed the GVWR or GAWR for either the front axle or rear axle.

1 Driver’s door B-pillar Following is a discussion on how to work with the information contained on the two placards with regards to loading your vehi- cle.

Tire and Loading Information

Tire and Loading Information placard

Warning!

Do not overload the tires by exceeding the specified load limit as indicated on the plac- ard on the driver’s door B-pillar. Overloading the tires can overheat them, possibly caus- ing a blowout. Overloading the tires can also result in handling or steering problems, or brake failure.

i Data shown on placard examples are for il- lustration purposes only. Load limit data are spe- cific to each vehicle and may vary from data shown in the illustrations below. Refer to placard on vehicle for actual data specific to your vehi- cle.

1 Load limit information on the Tire and

Loading Information placard

The placard showing the load limit informa- tion is located on the driver’s door B-pillar. 왘 Locate the statement “The combined weight of occupants and cargo should never exceed XXX kilograms or XXX lbs.” on this placard.

The combined weight of all occupants, car- go/luggage and trailer tongue load (if ap- plicable) should never exceed the weight referenced in that statement.

Operation Tires and wheels

Seating capacity The seating capacity gives you important information on the number of occupants that can be in the vehicle. Observe front and rear seating capacity. The Tire and Loading Information placard showing the seating capacity information is located on the driver’s door B-pillar (컄 page 336).

i Data shown on placard examples are for il- lustration purposes only. Seating data are specif- ic to each vehicle and may vary from data shown in the illustrations below. Refer to placard on ve- hicle for actual data specific to your vehicle.

load from your trailer will be trans- ferred to your vehicle. Consult this manual to determine how this reduces the available cargo and luggage load capacity of your vehicle (컄 page 340).

The following table shows examples on how to calculate total and cargo load capacities with varying seating configura- tions and number and size of occupants. The following examples use a load limit of 1500 lbs. This is for illustration purposes only. Make sure you are using the actual load limit for your vehicle stated on the vehicle’s placard (컄 page 337).

Operation Tires and wheels

Steps for determining correct load limit The following steps have been developed as required of all manufacturers under Title 49, Code of U.S. Federal Regulations, Part 575 pursuant to the “National Traffic and Motor Vehicle Safety Act of 1966”. Step 1
왘 Locate the statement “The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs.” on your vehicle’s placard.

Step 2
왘 Determine the combined weight of the

driver and passengers that will be riding in your vehicle.

Step 3
왘 Subtract the combined weight of the driver and passengers from XXX kilo- grams or XXX lbs.

339

Operation Tires and wheels

Certification label Even after careful determination of the combined weight of all occupants, cargo and the trailer tongue load (if applicable) (컄 page 340) as to not exceed the permis- sible load limit, you must make sure that your vehicle never exceeds the Gross Vehi- cle Weight Rating (GVWR) and the Gross Axle Weight Rating (GAWR) for either the front or rear axle. You can obtain the GVWR and GAWR from the certification la- bel. The certification label can be found on the driver’s door B-pillar, see “Technical data” (컄 page 476).

Gross Vehicle Weight Rating (GVWR): The total weight of the vehicle, all occupants, all cargo, and the trailer tongue load (컄 page 340) must never exceed the GVWR. Gross Axle Weight Rating (GAWR): The to- tal allowable weight that can be carried by a single axle (front or rear). To assure that your vehicle does not ex- ceed the maximum permissible weight limits (GVWR and GAWR for front and rear axle), have the loaded vehicle (including driver, passengers and all cargo and, if ap- plicable, trailer fully loaded) weighed on a suitable commercial scale.

Trailer tongue load The tongue load of any trailer is an impor- tant weight to measure because it affects the load you can carry in your vehicle. If a trailer is towed, the tongue load must be added to the weight of all occupants riding and any cargo you are carrying in the vehicle. The tongue load typically is 10 percent of the trailer weight and every- thing loaded in it. Your Mercedes-Benz has been designed primarily to carry passengers and their cargo. Mercedes-Benz does not recom- mend trailer towing with your vehicle.

Recommended tire inflation pressure

Warning!

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.

Your vehicle is equipped with either the Tire and Loading Information placard locat- ed on the driver’s door B-pillar (컄 page 336).

The tire inflation pressure should be checked regularly and should only be ad- justed on cold tires. The tires can be con- sidered cold if the vehicle has been parked for at least 3 hours or driven less than 1 mile (1.6 km). Follow recommended cold tire inflation pressures listed on Tire and Loading Information placard on the driver’s door B-pillar. Keeping the tires properly inflated provides the best handling, tread life and riding comfort. In addition to the Tire and Loading Information placard on the driver’s door B-pillar, also consult the fuel filler flap for any additional information pertaining to special driving situations. For more infor- mation, see “Important notes on tire infla- tion pressure” (컄 page 342).

i Data shown on placard examples are for il- lustration purposes only. Tire data are specific to each vehicle and may vary from data shown in the illustrations below. Refer to placard on vehi- cle for actual data specific to your vehicle.

Operation Tires and wheels

Important notes on tire inflation pressure

Warning!

If the tire inflation pressure repeatedly drops: 앫 Check the tires for punctures from

foreign objects.

앫 Check to see whether air is leaking from

the valves or from around the rim.

Tire temperature and tire inflation pressure are also increased while driving, depending on the driving speed and the tire load. If you will be driving your vehicle at high speeds of 100 mph (160 km/h) or higher, where it is legal and conditions allow, consult the placard on the inside of the fuel filler flap on how to adjust the cold tire in- flation pressure. If you do not adjust the tire inflation pressure, excessive heat can build up and result in sudden tire failure.

342

i Driving comfort may be reduced when the tire inflation pressure is adjusted to the value for speeds above 100 mph (160 km/h) as specified on the placard located on the inside of the fuel filler flap.

Be sure to readjust the tire inflation pressure for normal driving speeds. You should wait until the tires are cold before adjusting the tire inflation pressure. Some vehicles may have supplemental tire inflation pressure information for vehicle loads less than the maximum loaded vehi- cle condition. If such information is provid- ed, it can be found on the placard located on the inside of the fuel filler flap (컄 page 321). Tire inflation pressure changes by approxi- mately 1.5 psi (0.1 bar) per 18°F (10°C) of air temperature change. Keep this in mind when checking tire inflation pressure where the temperature is different from the outside temperature.

Checking tire inflation pressure

Regularly check your tire inflation pressure at least once a month. Check and adjust the tire inflation pressure when the tires are cold. The tires can be considered cold if the vehicle has been parked for at least 3 hours or driven less than 1 mile (1.6 km). If you check the tire inflation pressure when the tires are warm (the vehicle has been driven for several miles or sitting less than 3 hours), the reading will be approximately 4 psi (0.3 bar) higher than the cold reading. This is normal. Do not let air out to match the specified cold tire in- flation pressure. Otherwise, the tire will be underinflated.

Operation Tires and wheels

Warning!

Follow recommend 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 overheated.

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.

Do not overload the tires by exceeding the specified load limit or vehicle capacity weight as indicated on the placard on the driver’s door B-pillar. Overloading the tires can overheat them, possibly causing a blowout.

Checking tire inflation pressure manually Follow the steps below to achieve correct tire inflation pressure: 왘 Remove the cap from the valve on one

tire.

왘 Firmly press a tire gauge onto the

valve.

왘 Read tire inflation pressure on tire gauge and check against the recom- mended tire inflation pressure on the placard on the driver’s door B-pillar (컄 page 336). If necessary, add air to achieve the recommended tire inflation pressure.

i If you have overfilled the tire, release tire in- flation pressure by pushing the metal stem of the valve with e.g. a tip of a pen. Then recheck the tire inflation pressure with the tire gauge. 왘 Install the valve cap. 왘 Repeat this procedure for each tire.

Run Flat Indicator (Canada only) While the vehicle is being driven, the Run Flat Indicator monitors the set tire inflation pressures by evaluating each wheel’s rota- tional speed. This allows the system to de- tect a significant loss of pressure in a tire. If a wheel’s rotational speed changes due to falling tire inflation pressure, you will see a corresponding warning message in the multifunction display. The Run Flat Indicator may function in a restricted manner or with a delay 앫 if snow chains are mounted to the

vehicle

앫 in winter road conditions prevail in

presence of ice and snow

앫 if you are driving on a loose surface

(e.g. sand or gravel)

앫 if you are driving in a very sporty man- ner (involving rapid acceleration or high speeds in curves)

Warning!

Warning!

The Run Flat Indicator does not provide a warning for wrongly selected tire inflation pressures. Always adjust tire inflation pres- sure according to the placard on the driver’s door B-pillar or fuel filler flap.

The Run Flat Indicator does not replace reg- ular checks of the tire inflation pressures since a gradual pressure loss in more than one tire cannot be detected by the Run Flat Indicator.

The Run Flat Indicator is not able to issue a warning due to a sudden dramatic loss of tire inflation pressure (e.g. tire blowout caused by a foreign object). In this case bring the vehicle to a halt by carefully apply- ing the brakes and avoiding abrupt steering maneuvers.

When the multifunction display shows the message Tire pressure Check tires, one or more of your tires is significantly un- derinflated. You should stop and check your tires as soon as possible, and inflate them to the proper tire inflation pressure as indicat- ed on the vehicle’s tire information placard. 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 vehicle’s handling and stopping ability. Each tire, including the spare, should be checked monthly when cold and set to the recommended tire inflation pressure as specified in the vehicle placard and owner’s manual.

i The recommended tire inflation pressures for your vehicle can be found on the tire placard located on the driver’s door B-pillar (컄 page 336). The tire inflation pressures are not listed in the owner’s manual.

344

Reactivating the Run Flat Indicator The tire inflation pressure monitor must be reactivated in the following situations: 앫 If you have changed the tire inflation

pressure

앫 If you have replaced the wheels or tires 앫 If you have installed new wheels or

tires

왘 Using the tire placard on the driver’s door B-pillar or, if available, the inside of the fuel filler flap, make sure the tire inflation pressure of all four tires is cor- rect.

Warning!

The Run Flat Indicator can only warn you in a reliable manner if you have set the correct tire inflation pressures for each tire.

If an incorrect tire inflation pressure was set, the system will monitor the pressure ac- cording to the incorrect value.

Warning!

Warning!

The TPMS does not indicate a warning for wrongly selected inflation pressures. Always adjust tire inflation pressure according to the placard on the driver’s door B-pillar or, if available, the supplemental tire pressure in- formation on the inside of the fuel filler flap.

The TPMS is not able to issue a warning due to a sudden dramatic loss of pressure (e.g. tire blowout caused by a foreign object). In this case bring the vehicle to a halt by care- fully applying the brakes and avoiding abrupt steering maneuvers.

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 vehicle placard or the tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or the tire inflation pressure label, you should determine the proper tire infla- tion pressure for those tires). As an added safety feature, your vehicle has been equipped with a tire pressure monitor- ing system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires are significantly underinflated. Accord- ingly, when the low tire pressure telltale illu- minates, you should stop and check your tires as soon as possible. Driving on a signif- icantly underinflated tire causes the tire to overheat and can lead to tire failure.

Operation Tires and wheels

Underinflation also reduces fuel efficiency and tire tread life, and may effect the vehi- cle’s handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driv- er’s responsibility to maintain correct tire pressure, even if underinflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale.

i Operating radio transmission equipment (e.g. wireless headsets, two-way radios) in or near the vehicle could cause the TPMS to mal- function.

347

Operation Tires and wheels

Reactivating Advanced TPMS* The TPMS must be reactivated when you have adjusted the tire inflation pressure to a new level (e.g. because of different load or driving conditions). The TPMS is then recalibrated to the current tire inflation pressures.

Warning!

It is the driver’s responsibility to calibrate the TPMS on the recommended cold infla- tion pressure. Underinflated tires affect the ability to steer or brake the vehicle. You might lose control over the vehicle.

왘 Using the tire placard on the driver’s door B-pillar (컄 page 336) or, if avail- able, the supplemental tire pressure information on the inside of the fuel filler flap (컄 page 321), make sure the tire inflation pressure of all four tires is correct.

348

i Reactivate the TPMS after adjusting the tire inflation pressure to the inflation pressure rec- ommended for the vehicle operating condition. Tire pressure should only be adjusted on cold tires. Observe the recommended tire inflation pressure on the placard on the driver’s door B-pillar (컄 page 336). Some vehicles may have supplemental tire pressure information for driv- ing at high speeds (컄 page 342) or for vehicle loads less than the maximum loaded vehicle con- dition (컄 page 342).

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

General: Depending on the design standards used, the tire size molded into the sidewall may have no letter or a letter preceding the tire size designation. No letter preceding the size designation (as illustrated above): Passenger car tire based on European design standards. Letter “P” preceding the size designation: Passenger car tire based on U.S. design standards. Letter “LT” preceding the size designation: Light Truck tire based on U.S. design standards. Letter “T” preceding the size designation: Temporary spare tires which are high pressure compact spares designed for temporary emergency use only.

Tire width The tire width 1 (컄 page 350) indicates the nominal tire width in mm.

Aspect ratio The aspect ratio 2 (컄 page 350) is the dimensional relationship between tire section height and section width and is expressed in percentage. The aspect ratio is arrived at by dividing section height by section width.

Tire code The tire code 3 (컄 page 350) indicates the tire construction type. The “R” stands for radial tire type. Letter “D” means diagonal or bias ply construction; letter “B” means belted-bias ply construction. 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 example: 245/40 ZR 18). For additional information, see “Tire speed rating” (컄 page 352).

The tire load rating must always be at least half of the GAWR (컄 page 360) of your vehi- cle. Otherwise, tire failure may be the result which may cause an accident and/or seri- ous injury to you or others.

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

Do not overload the tires by exceeding the specified load limit as indicated on the plac- ard 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.

For additional information on tire load rating, see “Load identification” (컄 page 354). i Tire load rating 5 (컄 page 350) and Tire speed rating 6 (컄 page 350) are also referred to as “service description”.

Tire speed rating The tire speed rating 6 (컄 page 350) 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 se- rious injury and possible death, for you and for others.

i Tire load rating 5 (컄 page 350) and Tire speed rating 6 (컄 page 350) are also referred to as “service description”.

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 350) and the tire speed rating 6 (컄 page 350). If your tire includes “ZR” in the size designation and no service description 5 and 6 (컄 page 350) is given, the tire manufacturer must be consulted for the maximum speed ca- pability. If a service description 5 and 6 (컄 page 350) is given, the speed capa- bility is limited by the speed symbol in the service description. Example: 245/40 ZR18 97Y. In this example, “97Y” is the service description. The letter “Y” designates the speed rating and the speed capabil- ity of the tire is limited to 186 mph (300 km/h).

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.

Always follow the recommended tire inflation pressure (컄 page 341) 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, adverse- ly affect handling and fuel economy, and are more likely to fail from being overheated.

Do not overinflate tires. Overinflated tires can adversely affect handling and ride com- fort, wear unevenly, increase stopping dis- tance, and result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road de- bris, potholes etc.

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

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

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.

357

Operation Tires and wheels

Quality grades can be found, where appli- cable, 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 ex- ample, 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.

358

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 ex- cessive 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 Mo- tor 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.

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.

Traction The traction grades, from highest to low- est, are AA, A, B, and C. Those grades rep- resent 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.

Warning!

Tire ply material

The temperature grade for this tire is estab- lished for a tire that is properly inflated and not overloaded. Excessive speed, underin- flation, or excessive loading, either sepa- rately or in combination, can cause excessive heat build-up and possible tire failure.

1 Plies in sidewall 2 Plies under tread

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 336). 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.

Warning!

Have the tightening torque checked after changing a wheel. Wheels could become loose if not tightened with a torque of 96 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 432) and (컄 page 452).

If applicable to your vehicle’s tire configu- ration, tires can be rotated according to the tire manufacturer’s recommended in- tervals 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 neces- sary, according to the degree of tire wear. The same rotation (spinning) direction must be maintained (컄 page 336). 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.

Operation Winter driving

Before the onset of winter, have your vehicle winterized at an authorized Mercedes-Benz 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 “S” to a premixed windshield washer solvent/antifreeze which is formulated for temperatures below freezing point (컄 page 500). 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.

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 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 Can- ada (RAC) and have been designed specif- ically for use in snow conditions. Use of winter tires is the only way to achieve the maximum effectiveness of the ABS, ESP® and 4MATIC in winter operation. For safe handling, make sure that all mounted winter tires are of the same make and have the same tread design.

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 ve- hicle, you must place a notice to this effect where it will be seen by the driver. Such no- tices are available at your tire dealer or any authorized Mercedes-Benz Center.

Warning!

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.

364

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

Block heater* (Canada only)

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

Snow chains

! When driving with snow chains, always se- lect the raised level of the level control system Airmatic (컄 page 266). Other settings may result in damage to your vehicle.

! Even on vehicles with all-wheel-drive, use snow chains on rear tires only. Some tire sizes do not leave adequate clearance for snow chains. To help avoid serious damage to your vehicle or tires, make sure that the use of snow chains is permissible as specified in the “Technical data” section of this Operator’s Man- ual, see “Rims and tires” (컄 page 481).

Snow chains should only be driven on snow-covered roads at speeds not to ex- ceed 30 mph (50 km/h). Remove chains as soon as possible when driving on roads without snow. Please observe the following guidelines when using snow chains: 앫 Use of snow chains is not permissible

with all wheel/tire combinations (컄 page 481).

앫 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. 앫 Only use snow chains that are ap-

proved by Mercedes-Benz. Any autho- rized Mercedes-Benz Center will be glad to advise you on this subject.

Operation Winter driving

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

앫 Do not use snow chains on the spare

wheel (컄 page 487).

i When driving with snow chains, you may wish to switch off the ESP® (컄 page 102) before setting the vehicle in motion. This will improve the vehicle’s traction.

i E 63 AMG: Do not switch off the ESP® when driving in snow or with snow chains mounted.

i If the maintenance service indicator was in- advertently reset, have an authorized Mercedes-Benz Center correct it. Only reset if the proper maintenance service has been performed. Resetting the system without performing the proper service as called for by the maintenance service indicator will result in engine damage and/or other vehicle damage not covered by the Mercedes-Benz Limited Warranty.

왔 Vehicle care Cleaning and care of vehicle

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 de- signed for cleaning your vehicle.

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

While in operation, even while parked, your vehicle is subjected to varying external in- fluences which, if gone unchecked, can at- tack the paintwork as well as the vehicle underbody and cause lasting damage.

Such damage is caused not only by ex- treme 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 elimi- nates the aggressiveness and potency of the above adverse influences.

Operation Vehicle care

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 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
