In case of a flat tire, you may temporarily use the Minispare wheel when observing the following restrictions: 앫 Do not exceed a vehicle speed of

50 mph (80 km/h).

앫 Drive to the nearest tire repair facility

to have the flat tire repaired or replaced as appropriate.

앫 Do not operate vehicle with more than

one Minispare wheel mounted.

For more information, see “Rims and Tires” (컄 page 403).

1 Wheel bolt for light alloy rims 2 Wheel bolt for Minispare wheel (locat-

MOExtended system*

The MOExtended system allows you to continue driving your vehicle even if there is a total loss of pressure in one or more tires. You may only use the MOExtended system in conjunction with the Run Flat Indicator*.

! The maximum distance in emergency mode depends on the vehicle’s load. It is 30 miles (50 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 distance begins in emergency mode is when the warning message appears in the multifunction display indicating that there is a loss of tire inflation pressure. Do not exceed the maximum speed of 50 mph (80 km/h).

382

Warning!

In emergency mode, your vehicle’s driving characteristics are diminished in such situa- tions as: 앫 driving around curves 앫 while braking 앫 while accelerating rapidly Therefore, your driving style must be adapt- ed 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 ve- hicle 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 앫 you notice knocking sounds 앫 the vehicle starts to shake 앫 smoke develops and you smell rubber 앫 ESP® is intervening continuously 앫 you 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.

i When replacing individual or all tires on the vehicle, make sure only matching tires marked with “MOExtended” are mounted in the size specified for your vehicle (컄 page 403).

Practical hints Jump starting

Warning!

! Vehicles with automatic transmission and/or 4MATIC: Do not tow-start the vehicle.

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 very 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.

386

! Avoid repeated and lengthy starting attempts. Do not attempt to start the engine using a bat- tery quick charge unit. If 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 catalyt- ic 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 at- tached to a battery.

If the battery is discharged, the engine can be started with jumper cables and the battery of another vehicle. Observe the following: 앫 Jump starting should only be performed

when the engine and catalytic con- verter are cold.

앫 Do not start the engine if the battery is

frozen. Let the battery thaw out first.

앫 Only jump start from batteries with the

same voltage rating (12V). Jump starting with a higher voltage battery could damage the vehicle’s electrical system, which will not be covered by the Mercedes-Benz Limited Warranty. 앫 Only use jumper cables with sufficient

cross-section and insulated terminal clamps.

앫 Always make sure the jumper cables are not on or near pulleys, fans, or oth- er parts that move when an engine is started or running.

Warning!

Keep flames or sparks away from battery. Do not smoke.

Observe all safety instructions and precau- tions when handling automotive batteries (컄 page 279).

The battery is located in the engine compartment on the right hand side. The terminals for jump starting are located in front of the battery. 왘 Make sure the two vehicles do not

touch.

왘 Turn off all electrical consumers. 왘 Apply the parking brake (컄 page 54). 왘 Make sure the gear selector lever* is set to position P (컄 page 153) (manual transmission: to Neutral (컄 page 149)).

왘 Open the hood (컄 page 274). 왘 Flip up cover from the positive under hood terminal 2 in front of the filter box (컄 page 383).

When circumstances do not permit the recommended towing methods, the vehicle may be towed with all wheels on the ground or front wheels raised (except vehicles with 4MATIC) only so far as necessary to have the vehicle moved to a safe location where the recommended towing methods can be employed.

! Vehicles with 4MATIC: Do not tow with one axle raised. Doing so could damage the transfer case, which is not covered by the Mercedes-Benz Limited Warranty. All wheels must be on or off the ground. Observe instructions for towing the vehicle with all wheels on the ground.

! If the vehicle is towed with the front axle raised (not permissible for vehicles with 4MATIC), the gear selector lever* must be in po- sition N (manual transmission: gear shift lever in neutral position) and the engine must be shut off (SmartKey in starter switch position 0 or 1). Oth- erwise the ESP® will immediately be engaged and will apply the rear wheel brakes. When towing the vehicle with all wheels on the ground, the gear selector lever* must be in position N (manual transmission: gears disen- gaged) and the SmartKey must be in starter switch position 2. When towing the vehicle with all wheels on the ground or the front axle raised, the vehicle may be towed only for distances up to 30 miles (50 km) and at a speed not to exceed 30 mph (50 km/h).

Practical hints Towing the vehicle

Mercedes-Benz recommends that the vehicle be transported with all wheels off the ground using flatbed or appropriate wheel lift/dolly equipment. This method is preferable to other types of towing.

! Vehicles with automatic transmission* and/or 4MATIC: Do not tow-start the vehicle.

! Use flatbed or wheel lift/dolly equipment with the SmartKey in the starter switch turned to position 0. Do not tow with sling-type equipment. Towing with sling-type equipment over bumpy roads will damage radiator and supports. To prevent damage during transport, do not tie down vehicle by its chassis or suspension parts. Switch off the automatic central locking (컄 page 143).

388

i To signal turns while being towed with the hazard warning flasher in use, switch on the igni- tion and activate the combination switch for the left or right turn signal in the usual manner – only the selected turn signal will operate. Upon canceling the turn signal, the hazard warn- ing flasher will operate again.

Warning!

With the engine not running, there is no power assistance for the brake and steering systems. In this case, it is important to keep in mind that a considerably higher degree of effort is necessary to brake and steer the ve- hicle. Adapt your driving accordingly.

Warning!

If circumstances require towing the vehicle with all wheels on the ground, always tow with a tow bar if: 앫 the engine will not run 앫 there is a malfunction in the power supply or in the vehicle’s electrical system

as that will be necessary to adequately control the towed vehicle.

Prior to towing the vehicle with all wheels on the ground, make sure the SmartKey is in starter switch position 2.

If the SmartKey is left in starter switch position 0 for an extended period of time, it can no longer be turned in the switch. In this case, the steering is locked. To unlock, remove SmartKey from starter switch and reinsert.

Practical hints Towing the vehicle

! When towing the vehicle with all wheels on the ground, please note the following: With the automatic central locking activated and the SmartKey in starter switch position 2, the ve- hicle doors lock if the left front wheel as well as the right rear wheel are turning at vehicle speeds of approx. 9 mph (15 km/h) or more. To prevent the vehicle doors from locking, deac- tivate the automatic central locking (컄 page 143). Towing of the vehicle should only be done using the properly installed towing eye bolt. Never at- tach tow cable, tow rope or tow rod to vehicle chassis, frame or suspension parts.

i If the battery is disconnected or discharged 앫 the SmartKey will not turn in the starter

switch. For more information, see “Battery” (컄 page 383) and “Jump starting” (컄 page 386).

앫 the gear selector lever will remain locked in position P. For information on manually un- locking the transmission gear selector lever see (컄 page 363).
