Possible causes/consequences and X Solutions At least one tire is deflating. X Carefully bring the vehicle to a halt, avoiding abrupt

steering and braking maneuvers.

X If necessary, change the wheel (Y page 465).

The tire inflation pressure in at least one tire is significantly below the reference value. X Carefully bring the vehicle to a halt, avoiding abrupt

steering and braking maneuvers.

X Check and adjust tire inflation pressure as required. X If necessary, change the wheel (Y page 465).

G Warning! Do not drive with a flat tire. A flat tire affects the ability to steer or brake the vehicle. You may lose control of the vehicle. Continued driving with a flat tire will cause excessive heat build-up and possibly a fire.

G 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 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.

What to do if … Lamps in instrument cluster Notes If any of the following lamps in the instrument cluster fails to come on during the bulb self- check when switching on the ignition, have the respective bulb checked and replaced if necessary.

When you switch on the ignition, all lamps in the instrument cluster come on. The high- beam headlamp indicator lamp and turn signal indicator lamps will only come on if activated. If a lamp in the instrument cluster fails to come on when the ignition is switched on, have it checked and replaced if necessary.

After the malfunction has been remedied, the combination low tire pressure/TPMS malfunction telltale goes out after a few minutes of driving.

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 placard on the driver’s door B- pillar or the tire inflation pressure label 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 placard or the tire inflation pressure label, 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 monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires are significantly underinflated. Accordingly, when the low tire pressure telltale illuminates, 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.

What to do if … 459

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 to trigger illumination of the TPMS low tire pressure telltale. USA only: 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 telltale. When the system detects a malfunction, the telltale will flash for approximately 1 minute and then

remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. When the malfunction indicator is illuminated, 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 telltale 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.

Possible causes/consequences and X Solutions The system is malfunctioning. X Have the system checked as soon as possible at an authorized

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.

Mounting the spare wheel Introduction X Prepare the vehicle as described

(Y page 465).

X Take the following out of the vehicle:

Rspare wheel Rjack Rvehicle tool kit Rwheel bolts for spare wheel

For information on where to find the respective items, see “Where will I find ...?” (Y page 412) and (Y page 413). i Vehicles without spare wheel are not

factory-equipped with the tools required for a wheel change such as a jack or a wheel wrench. Some tools required for a wheel change are specific to your vehicle. Contact an authorized Mercedes-Benz Center to obtain the tools approved for your vehicle. This section describes the wheel change using the tools approved and recommended for your vehicle.

Lifting the vehicle G Warning! When jacking up the vehicle, only use the jack which has been specifically approved by Mercedes-Benz for your vehicle. The jack is designed exclusively for jacking up the vehicle at the jack take-up brackets built into both sides of the vehicle. Make sure the jack arm is fully seated in the jack take-up bracket. The jack must always be vertical when in use, especially on inclines or declines. The jack is intended only for lifting the vehicle briefly for wheel changes. It is not suited for performing maintenance work under the vehicle. To help avoid personal injury, use the jack only to lift the vehicle during a wheel change.

Version: 2.11.8.1

Never get beneath the vehicle while it is supported by the jack. Keep hands and feet away from the area under the lifted vehicle. Always lower the vehicle onto sufficient capacity jackstands before working under the vehicle. Always make sure the electronic parking brake is engaged. In addition, block the wheels with wheel chocks or other sizeable objects before raising the vehicle with the jack. Do not disengage the electronic parking brake while the vehicle is raised. Make sure that the ground on which the vehicle is standing and where you place the jack is solid, level and not slippery. If necessary, use a large underlay. On slippery surfaces, such as tiled floors, you should use a non-slip underlay, for example a rubber mat. Do not use wooden blocks or similar objects to support the jack. Otherwise the jack may not be able to achieve its load-bearing capacity if it is not at its full height. Never start the engine when the vehicle is raised. Also observe the notes on the jack.

X Prevent the vehicle from rolling away by

blocking wheels with wheel chocks or other sizeable objects. When your vehicle is equipped with a wheel chock, it is included with the vehicle tool kit (Y page 412). For information on setting up the collapsible wheel chock, see (Y page 412).

When changing a wheel on a level surface: X Place a wheel chock or other sizeable

object in front of and another wheel chock or other sizeable object behind the wheel that is diagonally opposite to the wheel being changed.

Battery Safety notes A battery should always be sufficiently charged in order to achieve its rated service

life. Refer to Maintenance Booklet for battery maintenance intervals. If you use your vehicle mostly for short- distance trips, you will need to have the battery charge checked more frequently. When replacing a battery, always use a battery approved by Mercedes-Benz. If you do not intend to operate your vehicle for an extended period of time, contact an authorized Mercedes-Benz Center about steps you need to observe. G Warning! Observe all safety instructions and precautions when handling automotive batteries.

Risk of explosion.

Fire, open flames and smoking are prohibited when handling batteries. Avoid creating sparks. Battery acid is caustic. Do not allow it to come into contact with skin, eyes or clothing. Wear suitable protective clothing, especially gloves, apron and faceguard. Wear eye protection. Rinse any acid spills immediately with clear water. Contact a physician if necessary. Keep children away.

Follow the instructions in this Operator’s Manual.

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
