Poddomkrachivaniye and towage

Poddomkrachivaniye

The automobile jack is in an additional compartment under a trunk floor, near a spare wheel.

For the translation of a jack into position take it from the luggage compartment, wring out up and turn to the right against the stop a driving neck.

Before laying of a jack to the luggage compartment bring it to a transport state: develop a persistent finger to a jack support, wring out a neck up and turn to the left against the stop.

The regular jack is intended only for short-term raising of the car when replacing a wheel! Before performance of any works under the car it is necessary to establish it on special props.


The heel of a jack should be rested against a plain and firm surface. At friable soil use a special lining (in winter season it is useful to have a piece of a wide board in the car).

Park the car on the flat horizontal platform, whenever possible with a hard coating.

Firmly cock the parking brake.

At the corresponding complete set transfer the AT selector lever to situation "P".

Prop up antiretractable boots the wheel located on diagonal from a subject to replacement.


At implementation of the procedure on a bias it is necessary to enclose boots under both wheels of the second axis from descent.


Take from a luggage carrier the necessary tool (a jack, a balloon key) and a spare wheel (see the Head the Operation manual). Make assembly of a two-section balloon key.
At the corresponding complete set take off a protective cap of a disk, then weaken bolts of fastening of wheels.

Having hooked the screw-driver, remove an opening cap under installation of a jack. Openings under installation of a jack are in body thresholds behind arches of lobbies and ahead of arches of back wheels.


Rotating a driving neck, achieve a full separation of the wheel which is subject to replacement from the earth.

Fill a basic finger of a jack against the stop (completely) in a reception opening of a threshold. Bring a jack into strictly vertical position (even if the car is parked on a slope)

Turn out the top bolt of fastening of a wheel and screw instead of it the aligning pin from a set of the onboard tool. Turn out the remained bolts and make replacement of the failed wheel.

For fastening of wheels only company bolts with designation of the Mercedes-Benz logo have to be used

1 — the Bolts applied to fastening of wheels 8 Ѕ by Jx18 with the disks AMG on 5 openings
2 — the Bolts applied to fastening of wheels 7 Ѕ by Jx16 with stamped disks on 5 or 6 openings
3 — the Bolts applied to fastening of wheels 7 Ѕ by Jx16 with cast disks


Put the failed wheel and the tool on the regular places in the luggage compartment of the car.

Towage

Transportation of the emergency car on a tow truck platform.

For loading of the emergency vehicle on the tow truck towing eyes can be used, - at the corresponding complete set do not forget to transfer the AT selector lever to situation "N".

Fastening of the car is made only on wheels/disks.

In order to avoid damages do not fix the car for suspension bracket elements at all!

Towage of the emergency car

Strictly speaking, the emergency car should be towed with the driving (back) wheels which are torn off from the earth (even better - on a tow truck platform).

Models with AT

The cars equipped with AT can be towed by the forward course on all four wheels with a speed which is not exceeding 50 km/h and on distance no more than 50 km.



Non-compliance maximum speeds or distances of towage can lead to damage of the transmission.


Before towage check the level of transmission liquid (see the Section Check of the ATF Level, replacement of the AT filter of the Head Routine maintenance), - at the insufficient ATF level, it is necessary to make necessary adjustment, or to tow the car only with the driving wheels which are torn off from the earth.



Towage of the equipped car AT on long distances, and also with the failed transmission has to be made only with a separation of driving wheels from the earth, or with the shaft disconnected cardan! Ideally - on a tow truck platform. Make the following preparatory procedures:

   a) Release the parking brake;
   b) Start the engine;
   c) Transfer the selector lever to situation "D", then - to neutral ("N");
   d) Kill the engine;
   e) Turn the ignition key in situation 2 (do not leave it in situation 0 at all);
   f) The "Automatic Locking of Doors during the Movement" function can be switched off.

All models

Use the towing cable which is only specially intended for this purpose at towage of the emergency vehicle. Use of modern synthetic materials allowed to market towing cables of the elastic design minimizing danger of breaks as a result of hit of a sling under wheels of the towed car.



The most convenient and safe means of towage of the car on wheels is the rigid towing bar.


The towing element (cable/bar) has to cling only to a special towing eye, - at all not to a bumper or elements of a suspension bracket.

The back towing eye is located under a bumper, a forward towing eye on the right - on the right under a decorative cover. Enter a hand into a groove of a cover and remove the last, having left suspended on safety tapes.


At installation of a decorative cover track reliability of a zashchelkivaniye of the top clamp.
The driver of the towing car has to try to move as much as possible evenly, smoothly releasing coupling at gear shifting and, especially, at start-off from the place.


At control of the towed vehicle you watch that during the movement the cable constantly remained tense, - manipulating a foot brake, try not to allow sharp breakthroughs and arrivals on a proslablenny cable.
Do not forget to turn a key in the lock of ignition of the towed car in position of ON, otherwise inevitably there will be a blocking of a steering column. Besides, at the included ignition also indexes of turns and stoplights are activated.



Activation of indexes of turns at the switched-on alarm system leads to temporary shutdown of the last.


Remember that at the switched-off engine efficiency of braking of the car considerably decreases because the vacuum amplifier of brakes ceases to function. At the same time it is necessary to squeeze out a pedal of a foot brake with much big, than usually by effort. On the models equipped with the power steering when performing maneuvering the bigger effort should be put to a steering wheel.

Before a start of motion drivers of both vehicles (towing and towed) should coordinate among themselves a route.

The movement has to be carried out only with moderate speeds, along the shortest route and observance of traffic regulations. Avoid sharp braking, accelerations and maneuvering. Remember that at towage of the car on the region of the dirt road there is always a danger of demolition on a roadside.

After a detachment of plugs of the rechargeable battery or at the discharged rechargeable battery the electronic key in the ignition lock does not turn any more, and the lever of the AT selector remains blocked in situation "P". (Charging of the rechargeable battery is considered in the Head Routine maintenance or Start of the engine by means of the auxiliary rechargeable battery - address the materials Introduction to the Management).

Turning of an electronic key in the lock of ignition is possible only at the attached and charged rechargeable battery. If the electronic key in the lock of ignition does not give in to turning, the lever of the AT selector remains blocked in situation "P".

At towage with the lifted forward bridge or control of the parking brake at the stand for test of brakes the engine has to be switched off. Otherwise owing to the active braking action of electronic antistrange (ESP) there will be a damage of the brake system of the back bridge.

Towage for the purpose of start of the engine

Before starting start of the engine by method of towage of the car, it is necessary whenever possible to try to use the auxiliary power supply.

Try not to allow situations of locking of keys in salon when pushing the car, - activators of door locks work at rotation of the left forward wheel when the key is in situation 2.

Models with RKPP

Towage for the purpose of start of the engine has to be made at the connected rechargeable battery and turned in the lock situation 2 by the ignition key.

Start of the engine by method of pushing or towage has to be made only at the cold engine and the catalytic converter. Avoid repeated long attempts of start.

Models with AT

Start of the engine of the equipped AT by method of towage or pushing is not possible, - in case of need use the auxiliary power supply.
