270 Replacing wiper blades

Replacing wiper blades Safety notes G Warning! For safety reasons, switch off the wipers and remove the SmartKey from the starter switch (vehicles with KEYLESS-GO: Make sure the vehicle’s on-board electronics have status 0) before replacing a wiper blade. Otherwise, the wiper motor could suddenly turn on and cause injury. G Warning! Wiper blades are components that are subject to wear and tear. Replace the wiper blades twice a year, preferably in the spring and fall. Otherwise the windshield will not be wiped properly. As a result, you may not be able to observe surrounding traffic conditions and could cause an accident.

! To avoid damage to the hood, the wiper arms should only be folded forward when in the vertical position.

! Never open the hood when a wiper arm is

folded forward. Hold on to the wiper when folding a wiper arm back. If released, the force of the impact from the tensioning spring could crack the windshield. Do not allow a wiper arm to contact the windshield glass without a wiper blade inserted. Mercedes-Benz recommends that you have this work carried out at an authorized Mercedes-Benz Center.

You may only use the MOExtended system in conjunction with the tire pressure loss warning system (Y page 186), the TPMS (Y page 188), or the Advanced TPMS (Y page 190). The maximum distance in emergency mode depends on the vehicle’s load. It is 50 miles (80 km) if the vehicle is partially loaded and 18 miles (30 km) if the vehicle is fully loaded. The point at which the maximum driving

Flat tire 277

distance in emergency mode begins is when the warning message appears in the multifunction display indicating that there is a loss of tire inflation pressure. X Do not exceed the maximum speed of

50 mph (80 km/h). G Warning! In emergency mode, your vehicle’s driving characteristics are diminished in such situations as: Rdriving around curves Rwhile braking Rwhile accelerating rapidly Therefore, your driving style must be adapted accordingly. Avoid abrupt steering and driving maneuvers, as well as driving over obstacles (road curbs, potholes, or off-road areas). This is especially important if the vehicle is heavily loaded. The emergency driving distance that can be achieved greatly depends on the demands placed on the vehicle. Depending on speed, load, driving maneuvers, road conditions, outside temperature, etc., the distance can be significantly shorter or, if the vehicle is driven cautiously, somewhat longer. Do not continue driving in emergency mode if Ryou notice knocking sounds Rthe vehicle starts to shake Rsmoke develops and you smell rubber RESP® is intervening continuously Ryou notice tears on the tire sidewalls After driving in emergency mode, you must have the rims inspected by an authorized Mercedes-Benz Center to check if they are suitable for further use. The failed tire must be replaced in any case. When replacing individual or all tires on the vehicle, make sure only tires marked with “MOExtended” are mounted in the size specified for your vehicle (Y page 291).

Keep children away.

Follow the instructions in this Operator’s Manual.

A battery contains materials that can harm the environment if disposed of improperly. A large 12 V storage battery contains lead. Recycling of the battery is the preferred method of disposal. Many states (USA only) or provinces (Canada only) require sellers of batteries to accept the old battery for recycling. G Warning! Failure to follow these instructions can result in severe injury or death. Never lean over batteries while connecting. You might get injured. Battery fluid contains sulfuric acid. Do not allow this fluid to come in contact with eyes, skin or clothing. In case it does, immediately flush affected area with water and seek medical help if necessary. A battery will also produce hydrogen gas, which is flammable and explosive. Keep flames or sparks away from battery, avoid improper connection of jumper cables, smoking etc. G Warning! Do not place metal objects on the battery as this could result in a short circuit. Use leak-proof batteries only to avoid the risk of acid burns in the event of an accident. Take care that you do not become statically charged, e.g. by wearing synthetic clothing or rubbing against textiles. For this reason, you also should not pull or push the battery over carpets or other synthetic materials. Never touch the battery first. First touch the outside body of the vehicle in order to release any possible electrostatic charges.

Do not rub the battery with rags or cloths. The battery could explode if touched due to electrostatic charge or due to spark formation.

! The battery is a Valve-Regulated Lead Acid (VRLA) battery, also referred to as “fleece” battery. Such batteries do not require topping-up of the electrolyte level. VRLA batteries therefore do not have cell caps and the battery cover is non-removable. Do not attempt to open the battery as otherwise the battery will be damaged. VRLA batteries do not require topping-up of the electrolyte level. They cannot be opened to check the electrolyte level. However, the battery condition must be checked periodically by performing a battery conductance test. Refer to Maintenance Booklet for battery condition testing intervals. The factory-equipped battery may only be replaced with a battery that Rhas the same security features Ris of identical size Ris of identical voltage Ris of identical capacity

! As any other battery, the battery may

discharge if you do not operate the vehicle for an extended period of time. Have the battery disconnected at a qualified workshop or an authorized Mercedes-Benz Center in such a case. You may also connect an accessory battery charge unit expressly approved by Mercedes-Benz for your vehicle model to maintain the battery charge. Contact an authorized Mercedes- Benz Center for further information. The battery, the battery ventilation hose and the lateral plug must always be securely installed when the vehicle is in operation.

! Never loosen or detach battery terminal clamps while the engine is running or the SmartKey is in the starter switch or KEYLESS-GO button is in position 1. Otherwise the alternator and other electronic components could be severely damaged. Have the battery checked regularly at an authorized Mercedes-Benz Center.

G Warning! Failure to follow these directions will cause damage to the electronic components, and can lead to a battery explosion and severe injury or death. Never lean over batteries while connecting or jump starting. You might get injured. Battery fluid contains sulfuric acid. Do not allow this fluid to come in contact with eyes, skin or clothing. In case it does, immediately flush affected area with water, and seek medical help if necessary. A battery will also produce hydrogen gas, which is flammable and explosive. Keep flames or sparks away from battery, avoid improper connection of jumper cables, smoking, etc. Attempting to jump start a frozen battery can result in it exploding, causing personal injury. Read all instructions before proceeding.

! Do not tow-start the vehicle. You could

otherwise seriously damage the automatic transmission which is not covered by the Mercedes-Benz Limited Warranty.

! Jump starting should only be performed using the jump-start terminals located in the engine compartment. Avoid repeated and lengthy starting attempts. Do not attempt to start the engine using a battery quick-charge unit.

If the engine does not run after several unsuccessful starting attempts, have it checked at the nearest authorized Mercedes-Benz Center. Excessive unburned fuel generated by repeated failed starting attempts may damage the catalytic converter and may present a fire risk. Make sure the jumper cables do not have loose or missing insulation. Make sure the cable clamps do not touch any other metal part while the other end is still attached to a battery.

If the battery is discharged, the engine can be started with jumper cables and the fully charged battery of another vehicle or an equivalent starter pack. Observe the following: RAccess to the battery is not possible on all vehicles. If you cannot access the battery of the other vehicle, provide jump start power by an external battery or starter pack.

RJump starting should only be performed when the engine and catalytic converter are cold.

RDo not jump start the engine or charge the

battery if the battery is frozen. Let the battery thaw out first.

ROnly jump start from batteries with the

same voltage rating (12 V). Jump starting with a more powerful battery could damage the vehicle’s electrical system. Such damage will not be covered by the Mercedes-Benz Limited Warranty.
