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 339).
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 336).
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.

Certification label Even after careful determination of the combined weight of all occupants, cargo and the trailer tongue load (if applicable) (컄 page 339) 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 339) 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 the Tire and Loading Information placard located on the driver’s door B-pillar (컄 page 335).
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 placard. Keeping the tires properly inflated provides the best handling, tread life and riding comfort. In addition to the tire 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 information, see “Important notes on tire inflation pressure” (컄 page 341).
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.

1 Tire and Loading Information placard with recommended cold tire inflation pressures
The Tire and Loading Information placard lists the recommended cold tire inflation pressures for maximum loaded vehicle weight. The tire inflation pressures listed apply to the tires installed as original equipment.
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.
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.
Operation Tires and wheels
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.
341
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 335). 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 335). The tire inflation pressures are not listed in the owner’s manual.
Operation Tires and wheels
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

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.
346
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.
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 335) 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.
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 335). Some vehicles may have supplemental tire pressure information for driv- ing at high speeds (컄 page 341) or for vehicle loads less than the maximum loaded vehicle con- dition (컄 page 341).

Rim diameter The rim diameter 4 (컄 page 349) is the diameter of the bead seat, not the diameter of the rim edge. Rim diameter is indicated in inches (in).
Tire load rating The tire load rating 5 (컄 page 349) is a numerical code associated with the maximum load a tire can support. For example, a load rating of 91 corre- sponds to a maximum load of 1356 lb (615 kg) the tire is designed to support. See also “Maximum tire load” (컄 page 355) where the maximum load as- sociated with the load index is indicated in kilograms and lb.
Tire width The tire width 1 (컄 page 349) indicates the nominal tire width in mm.
Aspect ratio The aspect ratio 2 (컄 page 349) 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 349) 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 351).
Warning!
i Tire load rating 5 (컄 page 349) and Tire speed rating 6 (컄 page 349) are also referred to as “service description”.
The tire load rating must always be at least half of the GAWR (컄 page 359) of your vehi- cle. Otherwise, tire failure may be the result which may cause an accident and/or serious injury to you or others.
Always replace rims and tires with the same designation, manufacturer and type as shown on the original part.
Tire speed rating The tire speed rating 6 (컄 page 349) indicates the approved maximum speed for the tire.

Tire manufacturers are required to grade tires based on three performance factors: treadwear, traction and temperature resis- tance.
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
1 Treadwear 2 Traction 3 Temperature resistance

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.
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.
Operation Tires and wheels
Warning!
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.

Uniform Tire Quality Grading Standards A tire information system that provides consumers with ratings for a tire’s traction, temperature and treadwear. Ratings are determined by tire manufacturers using government testing procedures. The ratings are molded into the sidewall of the tire.
Vehicle maximum load on the tire Load on an individual tire that is determined by distributing to each axle its share of the maximum loaded vehicle weight and dividing it by two.
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 335). 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.
Operation Tires and wheels
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 335). 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.

왔 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 494). 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.
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 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.

Snow chains
! When driving with snow chains, always se- lect the raised level of the level control system Airmatic (컄 page 262). 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 480).
364
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 483).
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.
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 480).
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.
왔 Maintenance We strongly recommend that you have your vehicle serviced by an authorized Mercedes-Benz Center, in accordance with the Maintenance Booklet at the times called for by the maintenance service indi- cator display. Failure to have the vehicle maintained in accordance with the Maintenance Booklet and maintenance service indicator at the designated times/mileage will result in ve- hicle damage not covered by the Mercedes-Benz Limited Warranty.

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.
368
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
! Follow the instructions provided by the pow- er washer manufacturer on maintaining a dis- tance 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, seals, or other rubber parts.
i 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 prox- imity, i.e. within approximately 3 ft (approxi- mately 1 m), the vehicle could be inadvertently locked or unlocked.
Tar stains Quickly remove tar stains before they dry and become more difficult to remove. A tar remover is recommended.
Paintwork, painted body components
! Affixing stickers, magnets, 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, de- pending on the climate and washing deter- gent 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. 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.).

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 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.
i 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 prox- imity, i.e. within approximately 3 ft (approxi- mately 1 m), the vehicle could be inadvertently locked or unlocked.
370
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 dif-
fused 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 automatic climate control to air recir- culation mode (컄 page 216) or (컄 page 233).
! Do not clean your vehicle in an automatic touchless car wash which uses caustic spray. Otherwise the caustic spray will damage the paint or ornamental moldings.
If the vehicle is very dirty, prewash it be- fore running it through the automatic car wash.
Operation Vehicle care
! Make sure that the windshield wiper switch is set to M (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 dam- age to the mirrors.
i After running the vehicle through an auto- matic car wash, wipe any wax off of the wind- shield (컄 page 372) and the wiper blade inserts (컄 page 372). This will prevent smears and re- duce wiping noise which can be caused by resid- ual wax on the windshield. When leaving the car wash, make sure that the mirrors are folded out. Otherwise they may vibrate.
Ornamental moldings For regular cleaning and care of ornamen- tal moldings, use a damp cloth.
Headlamps, tail lamps, side markers, turn signal lenses 왘 Use a mild car wash detergent, such as
! 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 clean- er. If in doubt whether an ornamental molding is chrome-plated, contact an authorized Mercedes-Benz Center.
Mercedes-Benz approved Car Sham- poo, with plenty of water.
! Only use window cleaning solutions that are suitable for plastic lamp lenses. Window clean- ing solutions which are not suitable may damage the plastic lamp lenses of the headlamps. There- fore, do not use abrasives, solvents or cleaners that contain solvents. Never apply strong force and only use a soft, non-scratching cloth when cleaning the lenses. Do not attempt to wipe dirty lenses with a dry cloth or sponge. Otherwise you may scratch or damage the lens surface.

Cleaning the windows and the wiper blades
! The windshield wipers must be in a vertical position before folding them away from the wind- shield. They could otherwise damage the hood. Never open the hood when the wiper arms are folded forward. 왘 Make sure the hood is fully closed. 왘 Switch on the ignition (컄 page 38). 왘 Turn combination switch to wiper
setting u (컄 page 58).
왘 With wiper arms in vertical position,
switch off the ignition (컄 page 63).
For safety reasons, switch off wipers and re- move SmartKey from starter switch (vehi- cles with KEYLESS-GO*: Make sure the vehicle’s on-board electronics have status 0) before cleaning the windshield and/or the wiper blades. Otherwise, the wiper motor could suddenly turn on and cause injury.
! Do not pull on the wiper blade inserts. They could tear. 왘 Fold the wiper arms forward until they
snap into place.
왘 Clean the wiper blade inserts with a
clean cloth and detergent solution.
왘 Use a soft, clean cloth and a mild win-
dow cleaning solution on all outside and inside glass surfaces. An automotive glass cleaner is recom- mended.
1 Distronic system sensor cover 왘 Switch off the ignition (컄 page 38). 왘 Use a mild car wash detergent, such as
Mercedes-Benz approved Car Sham- poo, with plenty of water and a non-scratching cloth to clean sensor cover 1.
! To prevent scratches or damage, never ap- ply strong force and only use a soft, non-scratch- ing cloth when cleaning the sensor cover 1. Do not attempt to wipe dirty sensors with a dry cloth or sponge.
372
! Fold the windshield wiper arms back onto the windshield before turning the SmartKey in the starter switch or pressing the KEYLESS-GO start/stop button (vehicles with KEYLESS-GO*). Hold on to the wiper when folding the wiper arm back. If released, the force of the impact from the tensioning spring could crack the windshield.
! To clean the window interior, do not use a dry cloth, abrasives, solvents or cleaners con- taining solvents. Do not touch the inside of the front, rear or side windows with hard objects such as an ice scraper or ring. Doing so may damage the windows.
Light alloy wheels If possible, clean wheels once a week. 왘 Use Mercedes-Benz approved Wheel Care, a soft bristle brush and a strong spray of water for cleaning the light al- loy wheels.
! Only use acid-free cleaning materials. Acid may cause corrosion or damage the clear coat.
! The vehicle should not be parked for an ex- tended period of time immediately after it has been cleaned, especially not after the wheel rims have been cleaned with wheel rim cleaner. Wheel rim cleaners can lead to increased corro- sion of the brake disks and brake pads. Non-ap- proved wheel cleaners may also damage the wheel paint if the car is not driven after cleaning. Therefore, the vehicle’s brake system should al- ways be warmed-up before it is parked after cleaning. To do so, please drive your vehicle for several minutes to allow the brakes to dry. When applying Mercedes-Benz approved Tire Care and Mercedes-Benz approved Wheel Care products, take care not to spray them on the brake disks.
Operation Vehicle care
Plastic and rubber parts 왘 Use a gentle dishwashing detergent or mild detergent for delicate fabrics as a washing solution.
왘 Wipe with a cloth moistened in a luke-
warm solution. The surface may temporarily change color. If this is the case, wait for it to dry.
