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
and solid.
● Al

l passengers and particularly children
must
keep a safe distance from the work area.
● Turn on the hazard warning lights to warn
other roa
d users.
● Use the tyre mobility system only if you are
famili
ar with the necessary procedures. Oth-
erwise, you should seek professional assis-
tance.
● The tyre mobility set is intended for tempo-
rary
emergency use only until you can reach
the nearest specialised workshop.
● Replace the repaired tyre with the tyre mo-
bility
set as soon as possible. » 95

●
The sea l
ant is a health hazard and must be
cleaned immediately if it comes into contact
with the skin.
● Always keep the tyre mobility set out of the
reac
h of small children.
● Never use an equivalent jack, even if it has
been appro
ved for your vehicle.
● Always stop the engine, apply the hand-
brake l
ever firmly and engage gear if using a
manual gearbox, in order to reduce the risk of
vehicle involuntary movement. WARNING
A tyre filled with sealant does not have the
same per f

ormance properties as a conven-
tional tyre.
● Never drive faster than 80 km/h (50 mph).
● Avoid heavy acceleration, hard braking and
fas
t cornering.
● Drive for only 10 minutes at a maximum
speed of 80
km/h (50 mph) and then check
the tyre. For the sake of the environment
Dispose of used or expired sealant observing
any l

egal requirements. Note

 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

connection shearing off during towing (acci-
dent risk).
● If your car has a towing bracket, only use
speci
al towing ropes. Risk of accident! CAUTION
In vehicles fitted with a towing bracket, only
use s pec

ial tow bars to prevent damage to
the ball joint. These tow bars have been spe-
cially approved for use with towing brackets. Towing vehicles with a manual gear-

If you choose to change the engine compart-
ment l
amp
s yourself, remember that it is a
dangerous area ››› in Working in the en-
gine c omp
ar

tment on page 270.
Always use identical bulbs with the same
designation. The name can be found on the
base of the bulb holder.
Depending on how equipped the vehicle is,
there are different sets of headlights and tail
lights:
● Halogen headlights.
● Full-LED main headlights*
● Halogen headlights with LED daytime run-
ning lights*
● Re

ar bulb light
● LED rear light*
Ful
l-LED headlight system*
Full-LED headlights handle all light functions
(daylight, side light, turn signal, dipped
beam and route light) with light emitting di-
odes (LEDs) as a light source.
Full-LED headlights are designed to last the
lifetime of the car and light bulbs cannot be
replaced. In case of headlight failure, go to
an authorised workshop to have it replaced. WARNING
● Tak e p

articular care when working on com-
ponents in the engine compartment if the en-
gine is warm. Risk of burns.
● Bulbs are highly sensitive to pressure. The
glas
s can break when you touch the bulb,
causing injury.
● When changing bulbs, please take care not
to injure
yourself on sharp edges, in particu-
lar on the headlight housing. CAUTION
● Remo v

e the ignition key before working on
the electric system. Otherwise, a short circuit
could occur.
● Switch off the lights and the parking light
before c
hanging a bulb.
● Take good care to avoid damaging any com-
ponents. For the sake of the environment
Please ask your specialist retailer how to dis-
pose of u

sed bulbs in the proper manner. Note
● Ple a

se check at regular intervals that all
lighting (especially the exterior lighting) on
your vehicle is functioning properly. This is
not only in the interest of your own safety,
but also that of all other road users. ●
Bef or

e changing a bulb, make sure you
have the correct new bulb.
● Do not touch the glass part of the bulb with
your bar
e hands, use a cloth or paper towel
instead, since the fingerprints left on the
glass will vaporise as a result of the heat gen-
erated by the bulb, they will be deposited on
the reflector and will impair its surface.
● Depending on the level of equipment fitted
in the vehic
le, LEDs may be used for part or
all of the interior and/or exterior lighting.
LEDs have an estimated life that exceeds than
that of the car. If an LED light fails, go to an
authorised workshop for its replacement. 104
