raised
When towing your vehicle with the front axle
raised, it is important that you observe the
safety instructions (Y page 327).
Only vehicles without 4MATIC can be towed
with the front axle raised.
! Vehicles with 4MATIC must not be towed
with the front or rear axle raised; otherwise,
the transmission may be damaged.
Vehicles with 4MATIC may either be towed with
both axles on the ground or be loaded and trans- ported.
! The ignition must be switched off if you are
towing the vehicle with the front axle raised. Intervention by ESP
®
could otherwise dam-
age the brake system.
X On vehicles with KEYLESS-GO or the KEY-
LESS-GO start function: you must use the
key instead of the Start/Stop button
(Y page 145).
X Make sure that the vehicle is stationary.
X Turn the key to position 2in the ignition
lock.
X When the vehicle is stationary, depress the
brake pedal and keep it depressed.
X Vehicles with automatic transmission:

you reset the combination switch, the hazard warning lamps start flashing again. Transporting the vehicle
4MATIC vehicles or vehicles with auto-

The towing eye or trailer tow hitch can be used
to pull the vehicle onto a trailer or transporter if
you wish to transport it. Notes for 4MATIC vehicles
! Vehicles with 4MATIC must not be towed
with the front or rear axle raised; otherwise,
the transmission may be damaged. 330
Towing away and tow-startingBreakdown assistance
Vehicles with 4MATIC may only be either towed
away with both axles on the ground or be loadedup and transported.
If the vehicle has transmission damage or dam-
age to the front or rear axle, have it transported on a transporter or trailer.
In the event of damage to the electrical sys-
tem:
If the battery is defective, the automatic trans-
mission will be locked in position j. To shift the
automatic transmission to position i, you
must provide power to the vehicle's on-board
electrical system in the same way as when jump- starting (Y page 325).
Have the vehicle transported on a transporter or trailer. Tow-starting (emergency engine
starting)
! Do not tow-start vehicles with automatic
transmission. You could otherwise damage
the automatic transmission.
i You can find information on "Jump-starting"
under (Y page 325).
Before tow-starting, the following conditions
must be fulfilled: R the battery is connected
R the engine has cooled down
R the exhaust system has cooled down
When tow-starting, it is important that you
observe the safety notes (Y page 327) and the
legal requirements in each respective country.
X Switch on the hazard warning lamps
(Y page 118).
X Fit the towing eye (Y page 328).
X Secure the rigid towing bar or the towing

X Release the brake pedal.
X Tow-start the vehicle.
X Release the clutch pedal slowly; do not
depress the accelerator pedal while doing so. X
When the engine has been started, immedi-
ately depress the clutch pedal fully and shift
to neutral.
X Pull over at a suitable place and stop the vehi-
cle safely, paying attention to road and traffic
conditions.
X Use the electric parking brake to secure the
vehicle and prevent it from rolling away.
X Remove the rigid towing bar or towing rope.
X Remove the towing eye (Y page 329).
X Switch off the hazard warning lamps. Fuses

WARNING
If you manipulate, bridge or replace a faulty
fuse with a fuse of a higher amperage, the
electric cables could be overloaded. This may result in a fire. There is a risk of an accident
and injury.
Always replace faulty fuses with specified newfuses of the correct amperage.
! Only use fuses that have been approved for
Mercedes-Benz vehicles and which have the
correct fuse rating for the system concerned.
Only use fuses marked with an "S". Compo-
nents or systems could otherwise be dam-
aged.
! Make sure that no moisture can enter the
fuse box when the cover is open.
! When closing the cover, make sure that it is
lying correctly on the fuse box. Moisture seep-
ing in or dirt could otherwise impair the oper- ation of the fuses.
The fuses in your vehicle disconnect faulty cir-
cuits. If a fuse blows, all the components in the circuit and their functions will fail.
Blown fuses must be replaced with fuses of the same rating, which you can recognise by the
colour and fuse rating. The fuse ratings are listed
in the fuse allocation chart.
The fuse allocation chart is in the fuse box in the front-passenger footwell (Y page 332).
If the newly inserted fuse also blows, have the
cause traced and rectified at a qualified special- Fuses

the wheels or tyres have different dimensions.
The wheel brakes or suspension components may also be damaged. There is a risk of acci-
dent.
Interchange front and rear wheels only if the
wheels and tyres are of the same dimensions.
! On vehicles fitted with a tyre pressure mon-
itor, electronic components are located in the wheel.
Tyre-fitting tools should not be applied in thearea of the valve, as this could damage the
electronic components.
Only have tyres changed at a qualified spe-
cialist workshop.
Interchanging the front and rear wheels of dif-
fering dimensions can render the general oper-
ating permit invalid.
Observe the instructions and safety notes in the "Changing a wheel" section (Y page 342).
The wear patterns on the front and rear tyres
differ depending on the operating conditions.
Interchange the wheels before a clear wear pat-
tern has formed on the tyres. Front tyres typi-
cally wear more on the shoulders, while rear
tyres wear more in the centre.
On vehicles that have front and rear wheels of
the same size, you can interchange the wheels
every 5,000 to 10,000 km depending on the
degree of tyre wear. Ensure the direction of
rotation is maintained.
Clean the contact surfaces of the wheel and the
brake disc thoroughly every time a wheel is
interchanged. Check the tyre pressure and, if
necessary, restart the tyre pressure loss warn-
ing system or the tyre pressure monitor. Direction of rotation
Tyres with a specified direction of rotation have additional benefits, e.g. if there is a risk of aqua-
planing. These advantages can only be gained if the tyres are fitted corresponding to the direc-
tion of rotation.
An arrow on the sidewall of the tyre indicates its correct direction of rotation. Storing wheels
Store wheels in a cool, dry and preferably dark
place if they are not being used. Protect the
tyres against oil, grease, petrol and diesel. Fitting a wheel
Preparing the vehicle X
Stop the vehicle on solid, non-slippery and
level ground.
X Apply the electric parking brake manually.
X Move the front wheels to the straight-ahead
position.
X Vehicles with manual transmission: fully
depress the clutch pedal and engage first or
reverse gear.
X Vehicles with automatic transmission:
shift the transmission to position
j.
X Switch off the engine.
X Vehicles without KEYLESS-GO: remove the
key from the ignition lock.
X Vehicles with KEYLESS-GO start-function
or KEYLESS-GO: open the driver's door.
The vehicle electronics are now in position
u. This is the same as “key removed”.
X Vehicles with KEYLESS-GO start function
or KEYLESS-GO: remove the Start/Stop but-
ton from the ignition lock (Y page 144).
X If included in the vehicle equipment, remove
the tyre-change tool kit from the vehicle.
X Additionally secure the vehicle against rolling
away (Y page 166).
i Apart from some country-specific variants,
vehicles are not equipped with a tyre-change
tool kit. Some tools for changing a wheel are
specific to the vehicle. For more information
on which tools are required to perform a
wheel change on your vehicle, consult a quali-
fied specialist workshop.
Necessary tyre-changing tools may include,

ity
Note that the vehicle's gradient-climbing capa-
bility depends on the off-road conditions and the road surface conditions.
All vehicles (except GLA 220 (156.945),
Mercedes-AMG vehicles and vehicles with
4MATIC): maximum gradient climbing ability is
40 %.
Vehicles with 4MATIC: the maximum gradient
climbing ability is 65%.
Missing values for the GLA 220 (156.945) and
Mercedes‑AMG GLA 45 4MATIC models were
unavailable at time of going to print.
Carefully depress the accelerator pedal and
make sure that the wheels do not spin when
driving on steep terrain.
If the load on the front axle is reduced when
pulling away on a steep uphill slope, the front
wheels have a tendency to spin. 4ETS recogni-
ses this and brakes the wheels accordingly. The
rear wheel torque is increased and it is easier to pull away.

climbing ability (Y page 175). Trailer tow hitch
