Fuel tank not
closed cor-
rectly.Stop the vehicle and close the tank
flap properly.
Several warning and control lamps light up
for a few seconds when the ignition is switch-
ed on, signalling that the function is being verified. They will switch off after a few sec-
onds.
When the control lamp lights up
or
the
auxiliary heating and heater running off pet-
rol automatically switch off. WARNING
Driving with insufficient fuel reserve could re-
sult in the vehicle breaking down in traffic
and a serious accident.
● If the fuel level is too low then the fuel sup-
ply to the engine can become irregular espe-
cially on slopes.
● If the engine “is choked” or stalls due to
lack of or irregularity of the fuel supply, the
power steering as well as all of the driver as-
sistance systems including braking assis-
tance will stop working.
● Always refuel when there is only one quar-
ter of the fuel tank left to avoid running out of
fuel. CAUTION
● Always pay attention to any lit control
lamps and to the corresponding descriptions
and instructions to avoid damage to the vehi-
cle.
● Never run the fuel tank completely dry. An
irregular fuel supply may lead to ignition
faults and unburnt fuel could enter the ex-
haust system. This could damage the catalyt-
ic converter filter or the diesel particulate fil-
ter! Note

wheel could lock ››› .
WARNING
A vehicle with a flat battery should never be
towed.
● Never remove the key from the ignition
lock. Otherwise, the steering wheel lock
could suddenly lock. The vehicle would not
be controlled and a serious accident could
ensue. WARNING
When towing the vehicle, the handling and
braking efficiency change considerably.
Please observe the following instructions to
minimise the risk of serious accidents and in-
jury:
● As the driver of the vehicle being towed:
– The brake must be depressed must hard-
er as the brake servo does not operate.
Always remain aware to avoid collision
with the towing vehicle.
– More strength is required at the steering
wheel as the power steering does not op-
erate when the engine is switched off.
● As the driver of the towing vehicle:
– Accelerate gently and carefully.
– Avoid sudden braking and manoeuvres.
– Brake well in advance than usual and
brake gently. CAUTION
● Carefully fit and remove the towline anchor-
age and its cover to avoid damage to the ve-
hicle (e.g. paintwork).
● When towing, fuel could enter the catalytic
converter and cause damage! Instructions for tow starting
In general, the vehicle should not be started
by towing. Jump-starting is much more pref-
erable
› › ›
page 253.
For technical reasons, the following vehicles
can
not be tow started:
● Vehicles with an automatic gearbox.
● Vehicles with the Keyless Access locking
and ignition system, since the electronic
steering lock may not unlock.
● Vehicles with an electronic parking brake,
given that it is possible that the brake will
not be disengaged.
● If the vehicle battery is flat, it is possible
that the engine control units do not operate
correctly.
However, if your vehicle must absolutely be
tow-started (manual gearbox):
● Put it into second or third gear.
● Keep the clutch pressed down. ●
Switch on the ignition and the hazard warn-
ing lights.
● Release the clutch when both vehicles are
moving.
● As soon as the engine starts, press the
clutch and move the gear lever into neutral.
This helps to prevent a collision with the tow-
ing vehicle. CAUTION
When tow-starting, fuel could enter the cata-
lytic converter and damage it. Towing instructions
Tow rope or tow bar
When towing, the tow bar is the safest and
vehicle friendly way. You should only use a
tow rope if you do not have a tow bar.
A tow rope should be slightly elastic to avoid
damage to both vehicles. It is advisable to
use a tow rope made of synthetic fibre or sim-
ilarly elastic material.
Only secure the tow rope or tow bar to the
towline anchorage or specially designed fit-
ting.
Vehicles with a
factory fitted towing device ,
can only
be used for towing with a tow bar,
s
pecially designed to fit on a tow hitch ball

Emergencies
Towing vehicles with an automatic gearbox
Note the following for a towed vehicle:
● Make sure the gear selector lever is in the N
position.
● Do not drive faster than 50 km/h (30 mph).
● Do not tow further than 50 km (30 miles).
● If a breakdown truck is used, the vehicle
must be towed with the front wheels raised.
Note the following instructions for towing
four all-wheel drive vehicles.
Instructions for towing all-wheel drive
vehicles
All-wheel drive vehicles can be towed using a
toolbar or tow rope. If the vehicle is towed
with the front or rear axle raised, the engine
must be turned off to avoid transmission
damage.
For vehicles with a double clutched DSG ®
(di-
rect shift gearbox) the instructions for towing
vehicles with an automatic gearbox apply
››› page 257 .
Sit uation
s in which the vehicle should not be
towed
In the following cases, the vehicle should not
be towed but transported on a trailer or spe-
cial vehicle:
● If the vehicle gearbox does not contain lu-
bricant due to a fault. ●
If the vehicle battery is flat and, as a result,
the electronic steering lock and electronic
parking brake cannot be disengaged if ap-
plied.
● If the vehicle to be towed has an automatic
gearbox and the distance to be covered is
greater than 50 km (30 miles). Note
● The vehicle can only be towed if the elec-
tronic parking brake and steering lock are de-
activated. If the vehicle has no power supply
or there is an electric system fault, the en-
gine must be started using jump leads to de-
activate the electronic parking brake and
electronic steering lock.
● Vehicles with the Keyless Access locking
and ignition system should only be towed
with the ignition connected since, otherwise,
the electronic steering lock will not unlock. Fitting the front towline anchorage

Advice
● After towing, remove the towline anchorage
by turning it clockwise and put the cover
b ac
k in place. CAUTION
The towline anchorage must always be com-
pletely and firmly tightened. Otherwise, it
could be released while towing and tow-start-
ing. Fitting the rear towline anchorage

vehicles with a facto-
ry
fitted towing bracket , there is no fitting be-
hind the cover to insert the towline anchor-
age. For towing, fit and use the tow hitch
››› page 179, ››› . Note the instructions for towing
››› page 256.
Fitting the towline anchorage to the rear for
vehicles without factory fitted tow hitch ● Take the towline anchorage from the vehi-
cle tool kit in the luggage compartment
››› page 244 .
● Pr e
ss on the upper cover and carefully re-
move it back. This may require some
strength. Allow the cover to hang.
● Screw in the towline anchorage into its po-
sition anticlockwise as far as it will go ›
›› .
Use a suitable tool to firmly tighten the tow-
line anchorage in its location.
● After towing, remove the towline anchorage
by turning it clockwise and put the cover
b ac
k in place. CAUTION
● The towline anchorage must always be
completely and firmly tightened. Otherwise,
it could be released while towing and tow-
starting.
● Vehicles with a factory fitted towing brack-
et, can only be used for towing with a tow
bar, specially designed to fit on a tow hitch
ball. Otherwise, the tow hitch ball and the ve-
hicle may be damaged. Otherwise, a tow rope
should be used. Towing advice
Towing requires some experience, especially
when using a tow rope. Both drivers should
be familiar with the technique required for
towing. For this reason, inexperienced drivers
should abstain.
While driving, avoid excessive traction forces
and jerking. When towing on an unpaved
road, there is always a risk of overloading
and damaging the anchorage points.
If the vehicle is towed, with the hazard warn-
ing lights on and the ignition switched on,
the turn signal may be used to indicate
changes of direction. Simply operate the turn
signal lever as usual. Meanwhile, the hazard
warning lights will go off. When the turn sig-
nal lever is returned to the rest position, the
hazard warning lights will be turned on auto-
matically.
Notes for the driver of the towed vehicle
●
Leave the ignition on to avoid locking the
steering wheel, to release the electronic
parking brake and to activate the turn sig-
nals, the horn as well as the window wipers
and window washers.
● As the power assisted steering does not
work if the engine is not running, you will
need more strength to steer than normally.
