The essentials
Towline anchorages
Att ac
h the b
ar or rope to the towline ancho-
rages.
The towline anchorages are located under
the floor panel in the luggage compartment,
next to the vehicle tools ›››
 page 95.
Screw the towline anchorage into the screw
connection ››› Fig. 77 o ››› Fig. 78 and tighten
it with the wheel brace.
Tow rope or tow bar
The tow bar offers increased safety and a
lower risk of damage.
The tow rope is recommended when there is
no tow bar. It must be elastic so that it does
not damage the vehicle.
Notes for the driver of the towing vehicle
● The tow rope must be taut before you drive
off.
● Rel

ease the clutch very carefully when start-
ing the v
ehicle (manual gearbox), or acceler-
ate gently (automatic gearbox).
Driving style
Towing requires some experience, especially
when using a tow rope. Both drivers should
realise how difficult it is to tow a vehicle. In-
experienced drivers should not attempt to
tow. Do not pull too hard with the towing vehicle
and take c

are to avoid jerking the tow rope.
When towing on an unpaved road, there is al-
ways a risk of overloading and damaging the
anchorage points.
Switch on the ignition so that the turn sig-
nals, windscreen wipers and windscreen
washer can work. Ensure that the steering
wheel is unlocked and moves freely.
Place the gear lever in neutral on vehicles
with a manual gearbox. With an automatic
gearbox, place the lever in N.
To brake, press the brake pedal firmly. The
brake servo does not work when the engine
is switched off.
The power steering only works when the igni-
tion is switched on and the vehicle is moving,
provided that the battery is sufficiently charg-
ed. Otherwise, it will need more force.
Ensure that the tow rope remains taut at all
times.

If the engine will not start, first try starting it
us
in

g the battery of another vehicle
››› page 70. You should only attempt to tow-
start a vehicle if charging the battery does
not work. This is done by leveraging wheel
movement.
When tow-starting a vehicle with a petrol en-
gine, do not tow it more than a short dis-
tance, otherwise unburned fuel can enter the
catalytic converter.
● Engage 2nd or 3rd gear before moving off.
● Press the clutch and hold the pedal down.
● Switch the ignition on.
● Once both vehicles are moving, release the
clut c

h.
● As soon as the engine has started, press
the clutc
h and move the gear lever to neutral.
How to jump start Jump lea
ds The jump lead must have a sufficient wire
c
r
o

ss section.
If the engine fails to start because of a dis-
charged battery, the battery can be connec-
ted to the battery of another vehicle to start
the engine. 70

The essentials
Jump leads must comply with standard DIN
72553 (see c ab
l
e manufacturer's instruc-
tions). The wire cross section must be at least
25 mm 2
for petrol engines and at least
35 mm 2
for diesel engines. Note
● The v ehic

les must not touch each other,
otherwise electricity could flow as soon as
the positive terminals are connected.
● The discharged battery must be properly
connected t
o the on-board network. How to jump start: description

The essentials
Make sure the battery clamps have sufficient
met al-t
o-met
al contact with the battery termi-
nals.
If the engine fails to start after about 10 sec-
onds, switch off the starter and try again after
about 1 minute. WARNING
● Ple a

se note the safety warnings referring to
working in the engine compartment
›››  page 270.
● The battery providing assistance must have
the same v
oltage as the flat battery (12V) and
approximately the same capacity (see imprint
on battery). Failure to comply could result in
an explosion.
● Never use jump leads when one of the bat-
teries
is frozen. Danger of explosion! Even af-
ter the battery has thawed, battery acid could
leak and cause chemical burns. If a battery
freezes, it should be replaced.
● Keep sparks, flames and lighted cigarettes
awa
y from batteries, danger of explosion.
Failure to comply could result in an explo-
sion.
● Observe the instructions provided by the
manufact
urer of the jump leads.
● Do not connect the negative cable from the
other vehic
le directly to the negative terminal
of the flat battery. The gas emitted from the
battery could be ignited by sparks. Danger of
explosion. ●
Never att ac

h the negative cable to fuel sys-
tem components or the brake lines in the oth-
er vehicle.
● The non-insulated parts of the battery
clamp
s must not be allowed to touch. The
jump lead attached to the positive battery
terminal must not touch metal parts of the ve-
hicle, this can cause a short circuit.
● Position the leads in such a way that they
cannot c
ome into contact with any moving
parts in the engine compartment.
● Do not lean on the batteries. This could re-
sult
in chemical burns. Note
The vehicles must not touch each other, oth-
erw i

se electricity could flow as soon as the
positive terminals are connected. Changing the wiper blades

Airbag system
such as the properties of the object the vehi-
c l
e hits
(hard/soft), angle of impact, vehicle
speed, etc.
Deceleration trajectory is key for airbag acti-
vation.
The control unit analyses the collision trajec-
tory and activates the respective restraint
system.
If the deceleration rate is below the prede-
fined reference value in the control unit the
airbags will not be triggered, even though
the accident may cause extensive damage to
the car.
The following airbags are triggered in seri-
ous head-on collisions:
● Driver airbag.
● Front passenger front airbag
● Knee airbag for the driver.
The fol
lowing airbags are triggered in seri-
ous side-on collisions:
● Front side airbag on the side of the acci-
dent.
● Re

ar side airbag on the side of the acci-
dent.
● Cur

tain (head) airbag on the side of the ac-
cident. In an ac

cident with airbag activation:
● the interior lights switch on (if the interior
light swit
ch is in the courtesy light position);
● the hazard warning lights switch on;
● all doors are unlocked;
● the fuel supply to the engine is cut.

The Anti-puncture kit* (Tyre Mobility System)
will reliably seal punctures caused by the
penetration of a foreign body of up to about
4 mm in diameter. Do not remove foreign ob-
jects, e.g. screws or nails, from the tyre.
After inserting the sealant residue in the tyre,
you must again check the tyre pressure about
10 minutes after starting the engine.
You should only use the tyre mobility set if
the vehicle is parked in a safe place, you are
familiar with the procedure and you have the
necessary tyre mobility set! Otherwise, you
should seek professional assistance.
Do not use the tyre sealant in the following
cases:
● If the wheel rim has been damaged.
● In outside temperatures below -20°C (-4°F). ●
In the ev ent
of

cuts or perforations in the
tyre greater than 4 mm.
● If you have been driving with very low pres-
sure or a c
ompletely flat tyre.
● If the sealant bottle has passed its use by
date. WARNING
Using the tyre mobility system can be dan-
ger ou

s, especially when filling the tyre at the
roadside. Please observe the following rules
to minimise the risk of injury:
● Stop the vehicle safely as soon as possible.
Park it
at a safe distance from surrounding
traffic to fill the tyre.
● Ensure the ground on which you park is flat

 page 69.
Tow-starting means starting the engine of
the vehicle while another pulls it.
Towing means one vehicle pulling another
that is not roadworthy.
If the vehicle comes with the Keyless Access
system, towing is only allowed with the igni-
tion on!
The vehicle battery drains if the vehicle is
towed with the engine switched off and the
ignition connected. Depending on the battery
charge status, the drop in voltage may be so
large, even after just a few minutes, that no
electrical device in the vehicle may work e.g.
the hazard warning lights. In vehicles with
the Keyless Access system, the steering
wheel could lock up. WARNING
If the vehicle has no electrical power, the
brak e light

s, turn signals and all other lights
will no longer function. Do not have the vehi-
cle towed away. Failure to follow this instruc-
tion could result in an accident. WARNING
The risk of accidents is high when tow-start-
ing, f or e

xample, the towed vehicle can easily
be driven into the towing vehicle. CAUTION
If there is no oil in the gearbox or no lubricant
in the autom atic

transmission the car may
only be towed with the driven wheels lifted
clear of the road, or transported on a special
car transporter or trailer. CAUTION
Do not tow a vehicle for more than 50 m in at-
tempt t

o start it. There is risk of damage to
the catalytic converter. Note
● Ple a

se observe related legal requirements.
● Switch on the hazard warning lights of both
vehicl
es. However, observe any regulations
to the contrary. 98

Self-help
●
The to w r
ope must not be twisted. Other-
wise the front tow line anchorage could be
pulled off the vehicle. Indications for tow-starting
Vehicle's should not generally be tow-star-
ted.
The jump s

tart should be used instead
›››  page 70.
For technical reasons, towing the following
vehicles is not allowed:
● Vehicles with an automatic gearbox.
● If the vehicle battery is discharged, be-
cau se in

vehicles with the Keyless Access
locking and ignition system the steering re-
mains locked and the electronic parking
brake cannot be deactivated nor can the elec-
tronic lock of the steering column be re-
leased if they are activated.
● If the battery is flat, it is possible that the
engine contr
ol units may not operate correct-
ly.
However, if the vehicle must absolutely be
tow-started (in the case of manual gearbox-
es):
● Engage the 2nd or 3rd gear.
● Keep the clutch pressed down.
● Switch on the ignition and the hazard warn-
ing lights. ●
Once both v
ehicles are moving, release the
clutch.
● Once the engine starts, press the clutch
and diseng
age the gear to avoid colliding
with the towing vehicle. Note
The vehicle can only be tow-started if the
electr onic

parking brake and, if appropriate,
the electronic lock of the steering column are
deactivated. If the vehicle has no power sup-
ply or there is an electric system fault, the
engine must be tow-started to deactivate the
electronic parking brake and the electronic
lock of the steering column. Anchoring the front tow line
