Using the air conditioning system economically
First read and observe the introductory information and safety warn-ings
on page 77.
The air conditioning system compressor uses power from the engine when in
cooling mode, which will affect the fuel consumption.
It recommended to open the windows or the doors of a vehicle for which the inte-rior has been strongly heated through the effect of direct sunlight in order to al-
low the heated air to escape.
The cooling system should not be switched on if the windows are open.
For the sake of the environment
Pollutant emissions are also lower when fuel is being saved » page 104.
Operational problems
First read and observe the introductory information and safety warn-
ings
on page 77.
If the cooling system does not operate at outside temperatures higher than +5 °C,
there is a problem in the system. The reasons for this may be.
› One of the fuses has blown. Check the fuse and replace if necessa-
ry » page 192 .
› The cooling system has switched off automatically for a short time because the
coolant temperature of the engine is too hot » page 11.
If you are not able to resolve the fault yourself, or if the cooling output has re- duced, switch off the cooling system and obtain assistance from a specialist ga-
rage.

The ball head is released in this position and falls freely into the hand. If it does
not fall freely into the hand, use your other hand to push it upwards.
At the same time, the ball head latches into the ready position and is thus readyto be re-inserted into the mounting recess »
.
›
Fit the cover for the mounting recess

» Fig. 100 on page 118 in the opposite
direction to the arrow.
›
Offer up the cap to the rear bumper
2
» Fig. 100 on page 118 aligning it with
“check mark” in the lower bumper area.
›
Push the cap in first on the left and right and then at the top.
WARNINGNever allow the ball head to remain unsecured in the boot. This could cause damage in a sudden braking manoeuvre and put the safety of the occupantsat risk.
CAUTION
■ If the lever is held firm and not pushed downwards as far as it can go, it will go
back up after the ball head is removed and will not latch into the ready position.
The ball head then needs to be brought into this position before the next time it
is fitted.■
Stow the ball head in the ready position with the key inserted in the box. When
doing so, make the side opposite to the inserted key face downwards – there is a
risk of damaging the key.
■
Do not use excessive force when handling the operating lever (e.g. do not step
on it).
Note
■ We recommend that you put the protective cap on the ball before removing the
ball head.■
Clean any dirt from the ball head before stowing it away in the box with the ve-
hicle tool kit.
Use and care
First read and observe the introductory information and safety warn-
ings
on page 118.
Close the mounting recess with the cap to prevent any ingress of dirt.
Always check the ball head before hitching a trailer. Apply a suitable grease where necessary.
Fit the protective cap when stowing away the ball head to protect the luggage
compartment against dirt.
In the event of dirt, clean the surfaces of the mounting recess and treat with a
suitable preservative.
CAUTION
Apply grease to the upper part of the mounting recess. Make sure you do not re-
move any grease.
Trailer
Introduction
This chapter contains information on the following subjects:
Loading a trailer
121
Towing a trailer
122
Anti-theft alarm system
123WARNINGAlways drive particularly carefully with the trailer.
Loading a trailer
First read and observe the introductory information and safety warn-
ings
on page 121.
The vehicle/trailer combination must be balanced, whereby the maximum permis-
sible drawbar load must be utilised. If the drawbar load is too low, it jeopardises the performance of the vehicle/trailer combination.
Distribution of the load
Distribute the load in the trailer in such a way that heavy items are located as close to the axle as possible. Secure the items from slipping.
121Towing a trailer
The distribution of the weight is very poor if your vehicle is unladen and the trail-
er is laden. Maintain a particularly low speed if you cannot avoid driving with this
combination.
Tyre pressure
Correct the tyre inflation pressure on your vehicle for a “full load” » page 174,
Tyre service life .
Trailer load
The permissible trailer load must not be exceeded under any circumstan- ces » page 201 , Technical data .
The trailer loads specified apply only to altitudes up to 1 000 metres above mean
sea level.
The engine output falls as altitude increases, as does the ability to climb. There-
fore, for every additional 1000 m in height (or part), the maximum permissible
towed weight must be reduced by 10 %.
The towed weight comprises the actual weights of the (loaded) towing vehicleand the (loaded) trailer.
The trailer and drawbar load information on the type plate of the towing equip- ment are merely test data for the towing equipment. The vehicle-specific values
are detailed in the vehicle documents.WARNING■ Do not exceed the maximum permissible axle and drawbar load and the
maximum permissible total or towed weight of the vehicle and the trailer –
there is the risk of an accident and serious injury.■
Slipping loads can significantly affect the stability and safety of the vehicle/
trailer combination – there is the risk of an accident and serious injury.
Towing a trailer
First read and observe the introductory information and safety warn-
ings
on page 121.
Exterior mirrors
You have to have additional exterior mirrors fitted if you are not able to see the
traffic behind the trailer with the standard rear-view mirrors. National legal re-
quirements must be observed.
Headlights
The front of the vehicle can be lifted when a trailer is being towed and the head-
lights can dazzle other road users.
Adjust the headlight setting on the headlight range control » page 44, Headlight
beam adjustment .
Driving speed
For safety reasons, do not drive faster than 80 km/h when towing a trailer.
Immediately reduce your speed as soon as even the slightest swaying of the trail- er is detected. Never attempt to stop the trailer from “swaying” by accelerating.
Brakes
Apply the brakes in good time! If the trailer is fitted with a trailer brake, apply the
brakes gently at first, then brake firmly. This will avoid brake jolts resulting from
the trailer wheels locking.
On downhill sections shift down a gear in good time to also use the engine as a
brake.
Engine overheating
The speed must be reduced immediately if the needle for the coolant tempera- ture gauge moves into the right-hand area or the red area of the scale.
Stop and switch off the engine if the warning light
in the instrument cluster
starts to flash. Wait a few minutes and check the level of coolant » page 167,
Checking the coolant level .
The following guidelines must be observed » page 22,
Coolant .
The coolant temperature can be reduced by switching on the heating.WARNING■ Adapt your speed to the conditions of the road surface and to the traffic sit-
uation.■
Improper or incorrectly connected electric cables can energise the trailer and
cause functional faults to the vehicle's entire electrical system as well as acci-
dents and severe injuries.
■
Work on the electrical system must only be carried out by specialist garages.
■
Never directly connect the trailer's electrical system with the electrical con-
nections for the tail lights or other current sources.
