There may be a delay in the reaction of the
tyre 
monitoring indicator or it may not in-
dic
ate anything under certain circumstances
(e.g. sporty driving, snow-covered or un-
paved roads, or when driving with snow
chains).
Calibrating the tyre monitoring
indicator Fig. 180
Glove compartment: tyre control
switch. After changing the tyre pressure or replacing
one or more wheels, the tyre monitoring indi-
cator must be recalibrated. Do the same, for
example, when the front and rear wheels are
swapped.
● Switch the ignition on.

ing the switch located in the glove compart-
ment* ››› Fig. 180 .
When driv in
g, the system self-calibrates the
tyre pressure provided by the driver and the
wheels fitted. After a long journey with varied
speeds the programmed values are collected
and monitored.
With the wheels under very heavy loads, the
tyre pressure must be increased to the total
recommended tyre pressure before the cali-
bration ››› page 243
. Note
● The tyre monitoring indicator does not
function when there is a fault in the ESC or
ABS ››› page 143.
● An err oneou

s indication may be given when
snow chains are in use because they increase
the tread of the wheel. Compact temporary spare
wheel

Vehicles with towline anchorage
On the right of the rear bumper there is a cov-
er which covers a threaded hole. – Take the towline anchorage out of the vehi-
cle tool set ››› page 220 .
– To r
emove the bumper cover, just press the
upper side of the cover inwards (arrow) and
remo

ve the cover by levering on the lower
››› Fig. 192 side.
– Scr

ew the towline anchorage into the screw
connection as far as it will go ››› Fig. 193
and tighten with the wheel brace.
After use, unscrew the towline anchorage
and put it back in the vehicle tool kit. Replace
the cover on the bumper. The towline anchor-
age should always be kept in the vehicle. WARNING
● If the towline anchorage is not screwed in
as far as the stop, there is a risk of the screw
connection shearing off during towing (acci-
dent risk).
● If your car has a towing bracket, only use
special towing ropes. Risk of accident! CAUTION
In vehicles fitted with a towing bracket, only
use special tow bars to prevent damage to
the ball joint. These tow bars have been spe-
cially approved for use with towing brackets. Tow-starting
As a general rule, tow-starting is not recom-
mended.
– 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
clutch.
– As soon as the engine has started, press
the clutch and move the gear lever to neu-
tral.
If the engine will not start, it is best to try
starting it using the battery of another vehi-
cle ›››

s t

art. You should only try to tow-start the en-
gine if jump starting is not successful. Tow-
starting is an attempt to start the engine via
the movement of the wheels.
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. WARNING
The risk of accidents is high when tow-start-
ing, for example, the towed vehicle can easily
be driven into the towing vehicle. CAUTION
Do not tow vehicles for more than 50 km. Risk
of damage to the catalytic converter. Towing vehicles with a manual
gearbox
Towing is relatively straightforward.

either the front or rear wheels lifted off the
road. The maximum towing speed is 50 km/h
(30 mph).
To

wing a vehicle equipped with
automatic gearbox Certain restrictions must be observed when
towing your vehicle.

replace fuses with a fuse of the same amper-
age (same colour and markings) and size.
● Never repair a fuse.
● Never replace a fuse by a metal strip, staple
or similar. CAUTION
● To prevent damage to the vehicle's electric
system, before replacing a fuse always turn
off the ignition, the lights and all electrical
elements and remove the key from the igni-
tion.
● If you replace a fuse with higher-rating
fuse, you could cause damage to another part
of the electrical system.
● Protect the fuse boxes when open to pre-
vent the entry of dust or humidity as they can
damage the electrical system. Note

(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.

● Take particular 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
glass 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
● Remove the ignition key before working on
the electric system. Otherwise, a short circuit
could occur. ●
Switch off the lights and the parking light
before changing 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 used bulbs in the proper manner. Note
● Please 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.
● Before changing a bulb, make sure you
have the correct new bulb.
● Do not touch the glass part of the bulb with
your bare 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. 234
