or ⇒
fig. 169 + of the vehicle with the flat bat-
tery A.
3. Connect the other end of the red jump lead to the positive ter-
minal +
in the vehicle providing assistance B.
4. On vehicles with no Start-Stop system , connect one end of the
black jump lead to the negative terminal -
in the vehicle pro-
viding assistance B ⇒ fig. 168.
5. On vehicles with the Start-Stop system , connect one end of the
black jump lead X
to a suitable ground terminal, to a solid
metal part bolted to the engine block or to the engine block it-
self ⇒ fig. 169.
6. Connect the other end of the black jump lead X
to a solid met-
al component bolted to the engine block or to the engine block
itself of the vehicle with the flat battery. Do not connect it to a
point near the battery A
.
7. Position the leads in such a way that they cannot come into contact with any moving parts in the engine compartment.
Starting
8. Start the engine of the vehicle with the boosting battery and let it run at idling speed.
9. Start the engine of the vehicle with the flat battery and wait one or two minutes until the engine is running.
Removing the jump leads
10. Before you remove the jump leads, switch off the headlights (if they are switched on). 11. Turn on the heater blower and heated rear window in the vehi-
cle with the flat battery. This helps minimise voltage peaks
which are generated when the leads are disconnected.
12. When the engine is running, disconnect the leads in reverse order to the details given above.
Connect the battery clamps so they have good metal-to-metal contact with
the battery terminals.
If the engine fails to start, switch off the starter after about 10 seconds and
try again after about half a minute.
WARNING
● Please note the safety warnings referring to working in the engine
compartment ⇒ page 194, Working in the engine compartment.
● The battery providing assistance must have the same voltage 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 batteries is frozen. Danger of
explosion! Even after 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 away from batteries, dan-
ger of explosion. Failure to comply could result in an explosion.
● Observe the instructions provided by the manufacturer of the jump
leads.
● Do not connect the negative cable from the other vehicle directly to
the negative terminal of the flat battery. The gas emitted from the battery
could be ignited by sparks. Danger of explosion.
● Do not attach the negative cable from the other vehicle to parts of the
fuel system or to the brake line.

242If and when
WARNING (Continued)
● The non-insulated parts of the battery clamps must not be allowed to
touch. The jump lead attached to the positive battery terminal must not
touch metal parts of the vehicle, this can cause a short circuit.
● Position the leads in such a way that they cannot come into contact
with any moving parts in the engine compartment.
● Do not bend over the batteries. This could result in chemical burns.
Note
The vehicles must not touch each other, otherwise electricity could flow as
soon as the positive terminals are connected.

243
If and when
Towing and tow-starting
Tow-starting*
The use of jump leads is preferable to tow-starting.
We recommend that you do not tow-start your vehicle. Jump-start-
ing is preferable ⇒ page 240.
However, if your vehicle has to be tow-started:
– Engage the 2nd or the 3rd gear.
– Keep the clutch pressed down.
– Switch the ignition on.
– Once both vehicles are moving, release the clutch.
– As soon as the engine starts, press the clutch and move the
gear lever into neutral. This helps to prevent driving into the
towing vehicle.
WARNING
The risk of accidents is high when tow-starting. The vehicle being towed
can easily collide with the towing vehicle.
CAUTION
When tow-starting, fuel could enter the catalytic converter and damage it. Comments
Please observe the following points if you use a tow-rope:
Notes for the driver of the towing vehicle
–
Drive slowly at first until the tow-rope is taut. Then accelerate
gradually.
– Begin and change gears cautiously. If you are driving an auto-
matic vehicle, accelerate gently.
– Remember that the brake servo and power steering are not
working in the vehicle you are towing. Brake sooner than nor-
mal and pressing the pedal gently.
Notes for the driver of the towed vehicle
– Ensure that the tow-rope remains taut at all times when towing.
Tow-rope or tow-bar
It is easier and safer to tow a vehicle with a tow-bar. You should only use a
tow-rope if you do not have a tow-bar.
A tow-rope should be slightly elastic to reduce the loading on both vehicles.
It is advisable to use a tow-rope made of synthetic fibre or similarly elastic
material.
Attach the tow-rope or the tow-bar only to the towing eyes provided or a
towing bracket.
Driving style
Towing requires some experience, especially when using a tow-rope. Both
drivers should be familiar with the technique required for towing. Inexper-
ienced drivers should not attempt to tow.
Safety FirstOperating InstructionsPractical TipsTechnical Specifications

244If and when
Do not pull too hard with the towing vehicle and take care to avoid jerking
the tow-rope. When towing on an unpaved road, there is always a risk of
overloading and damaging the anchorage points.
The ignition of the vehicle being towed must be switched on to prevent the
steering wheel from locking and also to allow the use of the turn signals,
horn, windscreen wipers and washers.
As the brake servo does not work if the engine is not running, you must ap-
ply considerably more pressure to the brake pedal than you normally would.
As the power assisted steering does not work if the engine is not running,
you will need more strength to steer than you normally would.
Towing vehicles with an automatic gearbox
● Put the selector lever into position “N”.
● Do not drive faster than 50 km/h.
● Do not tow further than 50 km.
● If a breakdown vehicle is used, the vehicle must be towed with the front
wheels raised.
Note
● Observe legal requirements when towing or tow-starting.
● Switch on the hazard warning lights of both vehicles. However, observe
any regulations to the contrary.
● For technical reasons, vehicles with an automatic gearbox must not be
tow-started.
● If damage to your vehicle means that there is no lubricant in the gear-
box, you must raise the drive wheels while the vehicle is being towed.
● If the vehicle has to be towed more than 50 km, the front wheels should
be raised during towing, and towing should be carried out by a qualified
person. ●
The steering wheel is locked when the vehicle has no electrical power.
The vehicle must then be towed with the front wheels raised. Towing should
be carried out by a qualified person.
● The towing eye should always be kept in the vehicle.
Towing eyesFig. 170 Fitting the tow-
ing eye to front rear of
the vehicle
Fitting the towing eye
– Take the towing ring from the on-board tool set.
– Remove the front cover by pressing down on its left-hand side.
For FR finishes, press down and pull outwards.
– Bolt the eye to its limit to the left, in the direction of the arrow
⇒ fig. 170.

Information on fuel consumption
Fuel consumption
The consumption and emission details shown on the vehicle
data sticker differ from one vehicle to another.
The vehicle's fuel consumption and CO 2 emissions can be consulted on the
vehicle data sticker in the spare wheel well, inside the luggage compart-
ment and on the rear cover of the Maintenance Programme.
The fuel consumption and CO 2 emission values refer to the weight category
assigned to your vehicle according to the engine and gearbox combination,
as well as the specific equipment fitted, and is only used to compare be-
tween the different models.
The fuel consumption and CO 2 emissions do not depend only on the per-
formance of the vehicle, they can also differ from the established values de-
pending on other factors such as driving style, road conditions, traffic con-
ditions, environmental conditions, load and number of passengers.
Calculation of fuel consumption
The consumption values have been calculated based on measurements per-
formed or supervised by certified CE laboratories according to the latest ver-
sion of directives 715/2007/EC and 80/1268/CEE (for more information
consult the European Union Publications Office at EUR-Lex: © European Un-
ion, http://eur-lex.europa.eu/en/index.htm) and are valid for the kerb
weight indicated for the vehicle.
Note
In practice, and considering all the factors mentioned here, consumption
values can differ from those calculated in the current European regulations. Weights
Kerb weight refers to the basic model with a fuel tank filled to 90% capacity
and without optional extras. The figure quoted includes 75 kg to allow for
the weight of the driver.
For special versions and optional equipment fittings or for the addition of
accessories, the weight of the vehicle will increase
⇒
.
WARNING
● Please note that the centre of gravity may shift when transporting
heavy objects; this may affect the vehicle's handling and lead to an acci-
dent. Always adjust your speed and driving style to suit road conditions
and requirements.
● Never exceed the gross axle weight rating or the gross vehicle weight
rating. If the allowed axle load or the allowed total weight is exceeded,
the driving characteristics of the vehicle may change, leading to acci-
dents, injuries and damage to the vehicle.
Towing a trailer Trailer weights
Trailer weight
The trailer weights and drawbar loads approved are selected in intensive tri-
als according to precisely defined criteria. The approved trailer weights are
valid for vehicles in the EU for maximum speeds of 80 km/h (in certain cir-
cumstances up to 100 km/h). The figures may be different in other coun-
tries. All data in the official vehicle documents take precedence over these
data ⇒
.

249
Description of specifications
Drawbar load
The maximum permitted drawbar load on the ball joint of the towing bracket
must not exceed 75 kg.
In the interest of road safety, we recommend that you always tow approach-
ing the maximum drawbar load. The response of the trailer on the road will
be poor if the drawbar load is too small.
If the maximum permissible drawbar load cannot be met (e.g. with small,
empty and light-weight single axle trailers or tandem axle trailers with a
wheelbase of less than 1 metre), a minimum of 4% of the actual trailer
weight is legally required for the drawbar load.
WARNING
● For safety reasons, do not exceed the 80 km/h limit. This is also valid
in countries where higher speeds are permitted.
● Never exceed the maximum trailer weights or the drawbar load. If the
permissible axle load or the permissible total weight is exceeded, the
driving characteristics of the vehicle may change, leading to accidents,
injuries and damage to the vehicle.
Wheels
Tyre pressure, snow chains, wheel bolts
Tyre pressures
The sticker with the tyre pressure values can be found on the inside of the
tank flap. The tyre pressure values given there are for cold tyres. The slightly
raised pressures of warm tyres must not be reduced. ⇒
Snow chains
Snow chains may be fitted only to the front wheels, and only for the follow-
ing tyres:
175/70R14
185/60R15Chains with links not exceeding 15 mm (including the chain
closure)
215/45R16Chains with links not exceeding 9 mm (including the chain
closure)
215/40R17Chains with links not exceeding 7 mm (including the chain
closure)
Wheel bolts
After the wheels have been changed, the tightening torque of the wheel
bolts should be checked as soon as possible with a torque wrench ⇒
.
The tightening torque for steel and alloy wheels is 120 Nm.
WARNING
● Check the tyre pressure at least once per month. Checking the tyre
pressure is very important. If the tyre pressure is too high or too low,
there is an increased danger of accidents, particularly at high speeds.
● If the torque of the wheel bolts is too low, they could loosen while the
vehicle is in motion. Risk of accident! If the tightening torque is too high,
the wheel bolts and threads can be damaged.
Note
We recommend that you ask your Authorised Service Centre for information
about appropriate wheel, tyre and snow chain size.
