Tire pressure monitoring system (USA only) Important safety information The tire pressure monitoring system consists of sensors installed in the vehicle wheels that monitor the air pressure in all four tires. The tire pressure monitoring system warns you when the pressure in one or more tires decreases. It only works when the

corresponding sensors are installed on all the wheels. The tire pressure monitor informs you via a yellow warning lamp in the instrument cluster about pressure loss or if the system is malfunctioning. Whether the warning lamp flashes or lights up indicates whether a tire pressure is too low or the tire pressure monitor is malfunctioning: RIf the warning lamp is lit up constantly, one

or more of your tires are significantly underinflated. The tire pressure monitor is not malfunctioning.

RIf the warning lamp flashes for 60 seconds and is then lit constantly, the tire pressure monitor is malfunctioning. G Warning! Each tire, including the spare (if provided), should be checked at least once a month when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the tire and loading information table on the driver's door B-pillar or the tire inflation pressure table 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 table or the tire inflation pressure table, you should determine the proper tire inflation pressure for those tires. As an added safety feature, your vehicle has been equipped with a tire pressure monitor (TPMS). An indicator lamp lights up if one or more of your tires are significantly underinflated. Accordingly, when the low tire pressure indicator lamp lights up, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. 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. Please note that the TPMS is not a substitute for proper tire maintenance and it is the driver's

responsibility to maintain correct tire pressure, even if underinflation has not reached the level at which the low tire pressure indicator lamp of the TPMS lights up. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure indicator lamp. When the system detects a malfunction, the indicator lamp will flash for approximately 1 minute and then remain illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. When the malfunction indicator is lit, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of incompatible replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction indicator after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly.

i If the tire pressure monitoring system

malfunctions, it may take up to 10 minutes before the malfunction is displayed to you by the tire pressure warning lamp flashing for 60 seconds and then remaining lit. When the error has been rectified, the tire pressure warning lamp goes out after a few minutes of driving.

Information on tire pressures is displayed in the multifunction display. After a few minutes of driving, the current tire pressure of each tire is shown in the multifunction display. i The tire pressure values in the on-board computer may deviate from the inflation pressure as measured using a tire pressure checker at the filling station. The tire pressures shown in the on-board computer refer to pressures at sea level. At high

altitudes, a tire pressure checker will display a higher tire pressure than the on- board computer. In this case do not reduce the tire pressure.

i If radio transmitting equipment (e.g. radio headphones, a two-way radio) is operated in or near the vehicle, this can lead to the function of the tire pressure monitor being impaired.

i This device complies with Part 15 of the

FCC Rules. Operation is subject to the following two conditions: 1. This device may not cause harmful interference, and 2. This device must withstand any interference received, including interference that may cause undesired operation. Any unauthorized modification to this device could void the user's authority to operate the equipment.

Monitor Active message appears instead of the tire pressure display. The tire pressures are already being monitored. i If a spare wheel is installed, the system may continue to show the tire pressure of the wheel that has been removed for a few minutes. If this occurs, note that the value displayed for the position where the emergency spare wheel/spare wheel is installed is not the same as the current tire pressure for the spare wheel.

TPMS warning messages If the TPMS detects a significant pressure loss on one or more tires, a warning message is shown in the multifunction display. In addition, a warning tone sounds and the tire pressure warning lamp lights up in the instrument cluster. Each tire in which a significant pressure loss has been detected is highlighted with a red triangle.

Restarting the tire pressure monitoring system G Warning It is the driver's responsibility to set the tire inflation pressure to the recommended cold tire inflation pressure. Underinflated tires affect the ability to steer or brake the vehicle. You might lose control over the vehicle.

When you restart the TPMS, all existing warning messages are deleted and the warning lamps go out. The currently set tire pressures are adopted as the specified values for monitoring. The TPMS must be restarted when you set the tire pressure to a new value (as a result of changed handling or load characteristics, for example). The TPMS then monitors the new tire pressure values. Restart the TPMS after the tire pressure has been set, as desired, according to the recommended values for the driving

conditions (Y page 326). Only correct tire pressures on cold tires. Comply with the tire pressures recommended on the Tire and Loading Information placard on the B-pillar on the driver's side. Additional tire pressure values for driving at high speeds or with heavy loads can be found in the tire pressure table on the inside of the fuel filler flap.

Maximum tire pressures

G Warning Never exceed the maximum 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 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.

Steps for determining the maximum cargo 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". X Step 1: Locate the statement "The combined weight of occupants and cargo should never

exceed XXX kg or XXX lbs." on your vehicle's Tire and Loading Information placard.

X Step 2: Determine the combined weight of the driver and passengers that will be traveling

X Step 3: Subtract the combined weight of the driver and passengers from XXX kilograms or

in your vehicle.

XXX lbs.

X Step 4: The resulting figure equals the available amount of cargo and luggage load capacity. For example, if the "XXX" amount equals 1400 lbs and there will be five 150 lbs passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs (1400 - 750 (5 x 150) = 650 lbs).

X Step 5: Determine the combined weight of luggage and cargo being loaded on the vehicle. For reasons of safety, that weight must not exceed the available cargo and luggage cargo capacity calculated in step 4.

X Step 6 (if applicable): If you intend to tow a trailer behind your vehicle, the load on the

trailer is transferred to your vehicle. Consult this manual to determine how this reduces the available cargo and luggage load capacity of your vehicle (Y page 338).

The following table shows examples on how to calculate total load and cargo capacities with varying seating configurations and number and size of occupants. The following examples use a cargo limit of 1 500 lbs (680 kg). This is for illustration purposes only. Make sure you always use the actual load limit for your vehicle stated on the vehicle's Tire and Loading Information placard (Y page 335).

Example 3
1500 lbs (680 kg) - 150 lbs (68 kg) = 1350 lbs (612 kg)

The greater the combined weight of the occupants, the lower the maximum luggage load. Further information can be found under "Towing a trailer" (Y page 338).

Vehicle identification plate Even if you have calculated the total cargo carefully, you should still make sure that the gross vehicle weight rating and the gross axle weight rating are not exceeded. Details can be found on the vehicle identification plate on the B-pillar on the driver's side (Y page 334). Gross vehicle weight: the gross weight of the vehicle, all passengers, cargo and trailer load/noseweight (if applicable) must not exceed the permissible gross vehicle weight.

Gross axle weight rating: the maximum permissible load that can be carried by one axle (front or rear axle). To ensure that your vehicle does not exceed the maximum permissible values (gross vehicle weight and maximum gross axle weight rating), have your loaded vehicle (including driver, occupants, cargo, and full trailer load if applicable) weighed on a suitable vehicle weighbridge.

338 Uniform Tire Quality Grading Standards

Trailer load/noseweight The trailer load/noseweight affects the gross weight of the vehicle. If a trailer is attached, the trailer load/noseweight is included in the load along with occupants and luggage. The trailer load/noseweight is usually approximately 8 % - 15 % of the gross weight of the trailer and its cargo.

Maximum tire load

G Warning Do not overload the tires by exceeding the specified load limit as indicated on the Tire and Loading Information placard 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.

Direction of rotation

Tires with a specified direction of rotation have additional benefits, e.g. if there is a risk of hydroplaning. You will only gain these benefits if the correct direction of rotation is observed. An arrow on the sidewall of the tire indicates its correct direction of rotation. You may mount an emergency spare wheel/ spare wheel against the direction of rotation. Observe the time restriction on use as well as the speed limitation specified on the emergency spare wheel/spare wheel.

i The actual values for tires are specific to

each vehicle and may deviate from the values in the illustration.

Maximum tire load : is the maximum permitted weight for which the tire is approved. Further information on tire loads (Y page 340).

The Uniform Tire Quality Grading Standards are U.S. government specifications. Their purpose is to provide drivers with uniform reliable information on tire performance data. Tire manufacturers grade tires using three performance factors: tread wear :, tire traction ; and heat resistance =. All tires sold in North America are provided with the corresponding quality class mark on the sidewall of the tire, even though these regulations do not apply to Canada. i The actual values for tires are specific to

each vehicle and may deviate from the values in the illustration.

Quality grades can be found, where applicable, on the tire sidewall between the tread shoulder and maximum tire width. For example: Tread wear Traction 200

Temperature

AA

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

Tread wear The tread wear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified U.S. government test track. For example, a tire graded 150 would wear one and one-half times as well on the government test track 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 conditions.

Traction G 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.

The traction grades, from highest to lowest, are AA, A, B, and C. These grades represent the tire's ability to stop on a wet surface as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance.

G Warning If ice has formed on the road, tire traction will be substantially reduced. Under such weather conditions, drive, steer and brake with extreme caution.

The safe speed on a wet, snow covered or icy road is always lower than on dry road surfaces. You should pay special attention to road conditions when temperatures are around the freezing point. Mercedes-Benz recommends a minimum tire tread depth of 1/6 in (4 mm) for all four winter tires (Y page 165) to maintain normal driving characteristics in winter. Winter tires can reduce the braking distance on snow covered surfaces in comparison to summer tires. The braking distance is still much further than on surfaces that are not icy or covered with snow. Take appropriate care when driving. ! Avoid wheelspin. This can lead to damage to the drive train which is not covered by the Mercedes-Benz warranty conditions.

Temperature G 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.

The temperature grades are A (the highest), B, and C, representing the tire's resistance 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 temperature 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.

Tire labeling Overview of tire labeling The following markings are on the tire in addition to the tire name (sales designation) and the manufacturer's name:

Interchanging the wheels

G 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. G Warning! Have the tightening torque checked after changing a wheel. The wheels could come loose if they are not tightened to a torque of 110 lb-ft (150 Nm). Only use genuine Mercedes-Benz wheel bolts specified for your vehicle’s rims.

The wear patterns on the front and rear tires differ, depending on the operating conditions. Rotate the wheels before a clear wear pattern has formed on the tires. Front tires typically wear more on the shoulders and the rear tires in the center. If your vehicle's tire configuration allows, you can rotate the wheels according to the intervals in the tire manufacturer's warranty book in your vehicle documents. If no warranty book is available, the tires should be rotated every 3000 to 6000 miles (5000 to 10000 km), or earlier if tire wear requires. Do not change the direction of wheel rotation. Clean the contact surfaces of the wheel and the brake disc thoroughly every time a wheel is rotated. Check the tire pressures.

General: depending on the manufacturer's standards, the size imprinted in the tire wall may not contain any letters or may contain one letter that precedes the size description. If there is no letter preceding the size description (as shown above): passenger vehicle tires according to European manufacturing standards. If "P" precedes the size description: passenger vehicle tires according to U.S. manufacturing standards. If "LT" precedes the size description: light truck tires according to U.S. manufacturing standards. If "T" precedes the size description: compact emergency spare wheels at high tire pressure, only for temporary use in an emergency. Tire width: tire width : shows the nominal tire width in millimeters. Aspect ratio: aspect ratio ; is relationship between tire height and tire width and is specified in percent. The aspect ratio is

Tire labeling 341

calculated by dividing the tire width by the tire height. Tire code: tire code = specifies the tire type. "R" represents radial tires. "D" represents diagonal tires, "B" represents diagonal radial tires. Optionally, tires with a maximum speed of over 149 mph (240 km/h) may have "ZR" in the size description depending on the manufacturer (e.g. 245/40 ZR 18). Rim diameter: rim diameter ? is the diameter of the bead seat, not the diameter of the rim flange. The rim diameter is specified in inches (in). Load bearing index: load bearing index A is a numerical code that specifies the maximum load-bearing capacity of a tire. G Warning The tire load rating must always be at least half of the GAWR of your vehicle. Otherwise, sudden tire failure may be the result which could cause an accident and/or serious injury to you or others. Always replace rims and tires with rims and tires having the same specifications (designation, manufacturer and type) as shown on the original part. G Warning Do not overload the tires by exceeding the specified load limit as indicated on the Tire and Loading Information placard 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.

Example: The load bearing index 91 is equivalent to a maximum load of 1356 lbs (615 kg) that the tire can carry. For further information on the maximum tire load in kilograms and pounds, see (Y page 338).

Wheel/tire combinations Points to remember G Warning Observe the "Important safety information" (Y page 324).

! For safety reasons, Mercedes-Benz recommends that you only use tires, wheels and accessories which have been approved by Mercedes-Benz specifically for your vehicle. These tires have been specially adapted for use with the control systems, such as ABS or ESP®, and are marked as follows: RMO = Mercedes-Benz Original RMOE = Mercedes-Benz Original Extended

(tires with run-flat characteristics)

RMO1 = Mercedes-Benz Original (AMG)

Only use Mercedes-Benz Original Extended tires on wheels that have been specifically approved by Mercedes-Benz. If you use other tires, wheels and accessories, Mercedes-Benz cannot accept any responsibility for damage that may result from this. Further information about tires, wheels and approved combinations can be obtained from any authorized Mercedes-Benz Center.

! If you mount tires other than those tested

and recommended by Mercedes-Benz, characteristics such as handling, noise levels and fuel consumption, etc. may be adversely affected. In addition, when driving with a load, tire dimensional variations could cause the tires to come into contact with the bodywork and axle components. This could result in damage to the tires or the vehicle.

i Further information about tires and

wheels can be obtained from any authorized Mercedes-Benz Center.

i The Tire and Load Information placard with the recommended tire pressures is attached to the B-pillar on the driver's side. Further information about driving at high speeds or driving with vehicle loads that are lighter than the maximum vehicle load can be found in the tire pressure table on the inside of the fuel filler flap. Check tire pressures regularly, and only when the tires are cold. Comply with the maintenance recommendations of the tire manufacturer in the vehicle document wallet.

Further information on the recommended tire inflation pressure and on tire pressures for specific driving conditions, see (Y page 326). i Notes on the vehicle equipment:

Ralways mount tires of the same size on a

given axle (left/right).

Ralways mount the same type of tires on

your vehicle at a given time (summer tires, winter tires, MOExtended tires).

i Vehicles featuring the MOExtended run- flat system are not equipped with a TIREFIT kit. It is therefore recommended that you additionally equip your vehicle with the TIREFIT kit if you mount tires that do not feature run-flat properties, e.g. winter tires. A TIREFIT kit is available from any qualified specialist workshop, e.g. an authorized Mercedes-Benz Center.

i The following pages contain information on approved wheel rims and tire sizes for equipping your vehicle with winter tires. Winter tires are not available at the factory as standard equipment or as an optional extra. If you want to equip your vehicle with approved winter tires, it may be necessary to obtain wheel rims in the corresponding size, as the size of the approved winter tires may differ from the standard tires. This is dependent on the model and the equipment installed at the factory. Tires, wheel rims and further information can be obtained at a qualified specialist workshop, e.g. an authorized Mercedes- Benz Center.
