Checklist (Continued) 7. When leaving the vehicle, take all keys with you.
8. Place an emergency warning triangle to indicate the position of your vehicle to other road users.
9. Allow the engine to cool and check if a specialist is required.
When being towed with the hazard warning lights system on, a change in
direction or traffic lane can be indicated as usual using the turn signals lev-
er. The hazard lights will be interrupted temporarily.
Examples of when to use the hazard warning lights system:
● If the vehicles ahead suddenly slow down or reach the end of a traffic
jam, to warn the vehicles behind.
● In case of an emergency.
● If the vehicle breaks down.
● When tow-starting or towing.
Always comply with the applicable laws regarding the use of hazard warn-
ing lights.
If the hazard warning lights system is not working, you must use an alterna-
tive method of drawing attention to your vehicle. This method must comply
with traffic legislation.
WARNING
Failure to follow the checklist prepared for your own safety could lead to
accidents and severe injuries.
● Always complete the operations given in the checklist and observe
the general rules of safety.
WARNING
The components of the exhaust system reach very high temperatures.
This could cause a fire and considerable damage.
● Always park your vehicle so that no part of the exhaust system can
come in contact with flammable materials (such as dried grass or fuel).
Note
The vehicle battery will discharge and run down if the hazard warning lights
remain on for too much time (even with the ignition turned off).
Note
For some vehicles, the brake lights will blink when braking suddenly at
speeds of approximately 80 km/h (50 mph) to warn vehicles behind. If brak-
ing continues, then the hazard warning lights system will automatically be
turned on at the speed of less than approximately 10 km/h (6 mph). The
brake lights remain lit. Upon accelerating, the hazard warning lights system
will be automatically turned off. 

Practical information
Starting
5. Start the engine of the vehicle with the boosting battery and let it run at idling speed.
6. 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
7. Before you remove the jump leads, switch off the headlights (if they are switched on).
8. When the engine is running, disconnect the leads in reverse or- der 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 182.
● 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.
WARNING (Continued)
● 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.
● 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. 

Towing and tow starting
Introduction
When towing or tow starting, respect the legal requirements.
For technical reasons, it is not possible to tow a vehicle if the battery is flat.
Additional information and warnings:
● Exterior detail ⇒ page 6
● Electronic power control and exhaust gases purification system
⇒  page 236
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. Then the vehicle will be uncontrollable.
You may lose control of the vehicle and there is a risk of serious accident.
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 injury:
● As the driver of the vehicle being towed:
– The brake must be depressed must harder 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 steer-
ing does not operate 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 towing ring and its cover to avoid damage to
the vehicle (for example, paintwork).
● When towing, fuel could enter the catalytic converter and cause dam-
age!
Note
Fitting a towline anchorage to the rear bumper is not possible. The vehicle is
not suitable for towing other vehicles. 

Practical information
Instructions for tow starting
In general, the vehicle should not be started by towing. Jump-starting is
much more preferable ⇒  page 273.
For technical reasons, the following vehicles can not be tow started:
● Vehicles with an automatic gearbox.
● If the vehicle battery is flat, it is possible that the engine control unit
does not operate correctly.
However, if your vehicle must absolutely be tow-started (manual gearbox):
● Engage the 2nd or 3rd gear.
● Keep the clutch pressed down.
● Switch on the ignition and the hazard warning 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 towing vehicle.
CAUTION
When tow-starting, fuel could enter the catalytic converter and damage it. 
Notes on towing
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 similarly elastic mate-
rial. Only secure the tow rope or tow bar to the tow ring or specially designed
fitting.
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) when towing a vehicle.
● 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.
Situations in which the vehicle should not be towed
In the following cases, the vehicle should not be towed but transported on a
trailer or special vehicle:
● If the vehicle gearbox does not contain lubricant due to a fault.
● If the battery is flat as the steering cannot be unlocked, as a result, the
electronic steering lock and electronic parking brake cannot be disengaged.
● 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 steering lock electronic gearbox lock is
deactivated. If the vehicle has no power supply or there is an electric system
fault, the engine must be started using jump leads to deactivate the steer-
ing column electronic gearbox lock. 

● Passengers.
● Total equipment.
● Roof load, included in the carrier.
WARNING
Exceeding the maximum authorised weight and the load on the axles
could cause damage to the vehicle, accidents and serious injuries.
● The real load on the axles should never exceed the maximum permit-
ted.
● The load and its distribution in the vehicle have effects on the vehicle
handling and the braking ability. Always drive at a suitable speed.
CAUTION
Distribute the load as uniformly and as low down on the vehicle as possible.
When transporting heavy objects in the luggage compartment, these
should be placed as far forward as possible or over the rear axle to have as
little influence on handling as possible. 
Information on fuel consumption
The consumption and emission values indicated do not refer to one specific
vehicle. They are only to be used to compare the values of the different ve-
hicle versions. The fuel consumption and CO 2 emissions of a vehicle not on-
ly depend on the effective use of fuel. They also depend on your driving
style and other non-technical factors.
Calculation of fuel consumption
Fuel consumption and emission values are determined according to the cur-
rent version of the 715/2007/EC or 80/1268/EEC regulation and are valid
for the vehicle kerb weight. The specifications do not refer to an individualvehicle. To measure the fuel consumption, two measuring cycles are carried
out on a rolling road test bed. The test criteria are as follows:
Urban cycleMeasurement of the urban cycle starts with an engine cold
start. City driving is then simulated at between 0 and 50 km/
h (0 and 31 mph).
Road cycle
In the road cycle simulation, the vehicle undergoes frequent
acceleration and braking in all gears, as in normal everyday
driving. The road speed ranges from 0 to 120 km/h (0 and
75 mph).
CombinedThe average combined consumption is calculated with a
weighting of around 37 % for the urban cycle and 63 % for
the road cycle.
CO
2 emis-
sions of the
combinationThe exhaust gases are collected during both driving cycles
to calculate carbon dioxide emissions (urban and road). The
gas composition is then analysed to evaluate the CO 2 con-
tent and other emissions.
Note
The kerb weight may vary according to the vehicle equipment. This could
raise consumption and the CO 2 emissions slightly.
Note
In practice, consumption values could be different to the values calculated
based on the 715/2007/EC or 80/1268/EEC regulations. 
