Maximum tire inflation pressure
1 Maximum permissible tire inflation
pressure
For illustration purposes only. Actual data on tires is specific to each vehicle and may vary from data shown in above illustration.
This is the maximum permissible tire inflation pressure for the tire.
334
Always follow the recommended tire inflation pressure (컄 page 320) 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 resistance.
1 Treadwear 2 Traction 3 Temperature resistance
For illustration purposes only. Actual data on tires is specific to each vehicle and may vary from data shown in above illustration.
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. 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
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.
335
Operation Tires and wheels
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.
336
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
For illustration purposes only. Actual data on tires is specific to each vehicle and may vary from data shown in above illustration.
This marking tells you about the type of cord and number of plies in the sidewall and under the tread.

Operation Tires and wheels
Rotating tires
Warning!
Rotate front and rear wheels only if they are of the same size. 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 314). 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.
340
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 6 000 miles (5000 to 10 000 km), or sooner if neces- sary, according to the degree of tire wear. The same rotation (spinning) direction must be maintained (컄 page 314). 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, activating the tire pressure mon- itoring system* if necessary.
If your vehicle is equipped with a tire pressure monitoring system*, there are electronic components built into the wheel. Do not use mounting tools in the area of the valve as they could damage the electronic components. To prevent damage or incorrect instal- lation, have the tires changed at an au- thorized Mercedes-Benz Center.
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 407) and (컄 page 425).
왔 Winter driving Before the onset of winter, have your vehi- cle winterized at an authorized Mercedes-Benz Center. This service in- cludes: 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 467).
앫 Battery test
Battery capacity drops with decreasing ambient temperature. A well charged battery helps to make sure that the en- gine can be started and the SBC brake system will be fully operational, even at low ambient temperatures.
앫 Tire change
Mercedes-Benz recommends M+S rat- ed radial-ply tires with a minimum tread depth of approximately 1/6 in (4 mm) on all four wheels for the winter sea- son.
Winter tires
Always use winter tires at temperatures below 45°F (7°C) and whenever wintry road conditions prevail. Use of winter tires is the only way to achieve the maximum ef- fectiveness 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.
Operation Winter driving
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.
Have the spare tire replaced with a winter tire at the nearest authorized Mercedes-Benz Center.

! Even on vehicles with all-wheel-drive, use snow chains on rear tires only. Use of snow chains is not permissible with tire sizes: 앫 265/35 ZR18
앫 T 155/70 R17 110M 앫 T 175/55-18 95POperation Winter driving
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.
When driving with snow chains, you may wish to deactivate the ESP (컄 page 89) before setting the vehicle in motion. This will improve the vehi- cle’s traction.
Snow chains
When driving with snow chains, always select the raised level of the level con- trol system Airmatic* (컄 page 248). Other settings may result in damage to your vehicle.
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.
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 ap-
proved by Mercedes-Benz. Your autho- rized Mercedes-Benz 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.

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.
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 underbody and cause lasting damage.
348
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.
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 followed by a thorough inspection. Dam- aged areas need to be re-undercoated. Your vehicle has been treated at the facto- ry 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 ap- plied later.
Operation Vehicle care
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 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 au- thorized Mercedes-Benz 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 prod- ucts.
Power washer When using a power wash for cleaning the vehicle, always observe the manufactur- er’s operating instructions.
Tar stains Quickly remove tar stains before they dry and become more difficult to remove. A tar remover is recommended.
Vehicles with KEYLESS-GO*: If a door handle is hit by a strong jet of water, and a SmartKey with KEYLESS-GO* is in close proximity, i.e. within approximately 3 ft (approxi- mately 1 m), the vehicle could be inad- vertently locked or unlocked.
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 connec- tors, seals, or other rubber parts.
Paintwork, painted body components Mercedes-Benz approved Paint Care should be applied when water drops on the paint surface do not“bead up”, normally every three to five months, depending on climate and washing detergent used. Mercedes-Benz approved Paint Cleaner should be applied if the paint surface shows signs of embedded dirt (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. Use the appropriate MB-Touch-Up Stick for quick and provisional repairs of minor paint damage (i.e. chips from stones, vehi- cle doors, etc.).
349
Operation Vehicle care
Engine cleaning Prior to cleaning the engine compartment, make sure to protect electrical compo- nents and connectors from contact with water and cleaning agents. Corrosion protection, such as MB Anticor- rosion Wax should be applied to the engine compartment after every engine cleaning. Before applying, all control linkage bush- ings and joints should be lubricated. The poly-V-belt and all pulleys should be pro- tected from any wax.
Vehicle washing Do not use hot water or wash your vehicle in direct sunlight. Only use a mild car wash detergent, such as Mercedes-Benz ap- proved Car Shampoo. Thoroughly spray the vehicle with a dif- fused jet of water. Direct only a very weak spray towards the ventilation intake. Use plenty of water and rinse the sponge and chamois frequently.
350
Rinse with clear water and thoroughly dry with a chamois. Do not allow cleaning agents to dry on the finish. 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. In the winter, thoroughly remove all traces of road salt as soon as possible. When washing the underbody, do not for- get to clean the inner sides of the wheels.
Vehicles with KEYLESS-GO*: If a door handle is hit by a strong jet of water, and a SmartKey with KEYLESS-GO* is in close proximity, i.e. within approximately 3 ft (approxi- mately 1 m), the vehicle could be inad- vertently locked or unlocked.
Ornamental moldings For regular cleaning and care of very dirty chrome-plated parts, use a chrome clean- er.
Headlamps, tail lamps, side markers, turn signal lenses Use a mild car wash detergent, such as Mercedes-Benz approved Car Shampoo, with plenty of water. To prevent scratches, never apply strong force and only use a soft, non-scratchy cloth when cleaning the lenses. Do not at- tempt to wipe dirty lenses with a dry cloth or sponge.

Problem H The yellow warning lamp for the tire pressure monitoring system comes on.
Possible cause The tire pressure monitoring system de- tects a loss of pressure in at least one tire.
Warning!
When the tire pressure monitoring system warning light is lit, one or more of your tires is significantly under-inflated. You should stop and check your tires as soon as possi- ble, and inflate them to the proper pressure as indicated on the vehicle’s tire information placard. Driving on a significantly under-in- flated tire causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehi- cle’s handling and stopping ability. Each tire, including the spare, should be checked monthly when cold and set to the recom- mended inflation pressure as specified in the vehicle placard and owner’s manual.
Practical hints What to do if …
Suggested solution 왘 Bring the vehicle to a halt, avoiding
abrupt steering and braking maneuvers. Observe the traffic situation around you. 왘 Take note of the messages in the multi-
function display.
The warning lamp goes out once the tire pressure monitoring system has been reac- tivated after the tire inflation pressures have been corrected.
The recommended tire inflation pres- sures for your vehicle can be found on the placard on the driver’s door B-pillar or the inside of the fuel filler flap, not in the owner’s manual.
