!
Pay particular attention to objects above
or below the sensors when parking, such
as flower pots or trailer towbars. Parktronic
does not detect such objects when they are
in the immediate vicinity of the vehicle. You
could damage the vehicle or the objects.
Ultrasonic sources such as an automatic
car wash, a lorry's compressed-air brakes
or a pneumatic drill could cause Parktronic
to malfunction.
Minimum distance Centre Approximately 20 cm
Corners Approximately 15 cm If there is an obstacle within this range, all
warning displays light up and a tone sounds.
If the distance falls below the minimum clear-
ance, it may no longer be shown.
Warning displays
The warning displays show the distance
between the sensors and the obstacle. The
warning display for the front area is located
on the dashboard above the centre air vents.
The warning display for the rear area is in the
roof trim at the rear.
Front area warning display
1
Left-hand side of the vehicle
2 Right-hand side of the vehicle
3 Indicator segments The warning display for each side of the vehi-
cle is divided into five yellow and two red
segments. Parktronic is operational if yellow
indicator segments
3 light up.
The selector lever position determines which
warning display is active: Selector lever at Warning display
D Front area activated
R or N Rear and front areas
activated
P No areas activated
One or more segments light up as the vehicle
approaches an obstacle, depending on the
vehicle's distance from the obstacle.
From the:
R
sixth segment onwards, you will hear an
intermittent warning tone for approxi-
mately two seconds.
R seventh segment onwards, you will hear a
warning tone for approximately two sec-
onds. You have reached the minimum dis-
tance. Controls

X Make sure pressure release screw a on
pressure gauge b is fully closed.
X Screw filler hose 8 onto valve 9.
X Insert plug 5 into the socket of the ciga-
rette lighter* (Y page 181) or into a 12V
power socket in your vehicle
(Y page 182).
X Turn the key to position 1 (Y page 74) in
the ignition lock. X
Press on/off switch 4 on the electric air
pump to I.
The electric air pump is switched on. The
tyre is inflated.
i First, TIREFIT is pumped into the tyre. The
pressure can briefly rise to around 5 bar.
Do not switch off the electric pump dur-
ing this phase.
X Let the electric pump run for five minutes.
The tyre should then have a pressure of at
least 1.8 bar.
! Do not operate the electric air pump for
longer than six minutes without a break.
Otherwise, it may overheat.
The air pump can be operated again once
it has cooled down.
If a pressure of 1.8 bar is not reached after
five minutes:
X Switch off and disconnect the electric air
pump and drive the vehicle forwards or
backwards approximately 10 m.
This distributes the TIREFIT more evenly.
X Remove TIREFIT filler bottle 1 from the
electric pump.
X Pump up the tyre again.
G Risk of accident
If a pressure of 1.8 bar is not achieved after
five minutes, the tyre is too badly damaged.
Do not drive any further. Consult a qualified
specialist workshop which has the neces-
sary specialist knowledge and tools to carry
out the work required. Mercedes-Benz rec-
ommends that you use a Mercedes-Benz
Service Centre for this purpose. In particu-
lar, work relevant to safety or on safety-
related systems must be carried out at a
qualified specialist workshop.
If a tyre pressure of 1.8 bar is reached:
X Press on/off switch 4 on the electric air
pump to 0.
The electric air pump is switched off.
X Disconnect the electric air pump and stow
it away.
X Fold up the warning triangle and stow it
away.
X Pull away immediately.
This distributes the TIREFIT more evenly
around the tyre.
X Stop after driving for approximately ten
minutes and check the tyre pressure with
the electric air pump.

it away.
Lowering the vehicle X
Lower the vehicle. To do this, turn the crank
of the jack anti-clockwise until the vehicle
is standing firmly on the ground again.
X Place the jack to one side. 1
– 5 Wheel bolts
X Tighten the wheel bolts evenly in a cross-
wise pattern in the sequence indica-
ted ( 1 to 5). The tightening torque must
be 130 Nm. G
Risk of accident
Have the tightening torque checked imme-
diately after a wheel is changed. The wheels
could work loose if they are not tightened
to a tightening torque of 130 Nm.
X Turn the jack back to its initial position and
store it and the rest of the vehicle tool kit
in the boot.
Vehicles with the "Minispare"/collapsible
emergency spare wheel*:
X Wrap the faulty wheel in the protective film
provided with the "Minispare"/collapsible
emergency spare wheel* and transport the
wheel in the boot.
or
X Depending on the size of the wheel, the
faulty wheel may also be secured in the
spare wheel recess. In this case, the stow-
age well casing will have to be removed
from the spare wheel well and stowed in the
boot.
i Do not activate the tyre pressure moni-
tor* until the deflated tyre has been
removed from the vehicle. Practical advice

Towing and tow-starting
293Towing and tow-starting
Points to remember
G
Risk of accident
If you tow the vehicle, you must use a rigid
towing bar if:
R the engine is not running
R there is a brake system malfunction
R the voltage supply or the vehicle's elec-
trical system is damaged
There
is no power assistance for the steer-
ing when the engine is not running. G
Risk of accident
The vehicle is braked when HOLD is activa-
ted.
Therefore, deactivate HOLD if the vehi-
cle is to be towed.
If you tow or tow-start another vehicle, its
weight must not exceed the maximum per-
missible gross vehicle weight of your vehi-
cle.
It is better to have the vehicle transported
than to have it towed.
When towing, observe the legal requirements
in all countries concerned. !
When towing, pull away slowly and with-
out

jerking. If the tractive power is too high,
the vehicles could be damaged. Do not use
the towing eye for recovery.
! You may tow the vehicle for a maximum
of 50 km. A towing speed of 50 km/h must
not be exceeded.
With towing distances over 50 km, the
entire vehicle needs to be lifted up and
transported.
! Only secure the tow cable or towing bar
to the towing eyes. You may otherwise
damage the vehicle.
R Vehicles with an automatic transmission
must not be tow-started.
R If the engine does not start, try jump-start-
ing it (Y page 291).
R If it is not possible to jump-start the vehicle,
have it towed to the nearest qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre.
R If the vehicle has suffered transmission
damage, only tow it with the propeller shaft
disconnected.
R The selector lever must be in position N on
vehicles with automatic transmission. R
If you are towing the vehicle over a consid-
erable distance, this may only be done with
the rear axle raised.
R The ignition must be switched off if you are
towing the vehicle with the front/rear axle
raised. Intervention by ESP ®
could other-
wise damage the brake system.
R Before towing the vehicle, make sure that
the battery is connected and charged. Oth-
erwise:
-You cannot switch on the ignition
- You cannot move the selector lever to N
- You have no support when braking
i Switch off the automatic locking feature
before the vehicle is towed (Y page 127).
You could otherwise be locked out when
pushing or towing the vehicle. Practical advice
