Driving Tips
–
Do not, as far as possible, drive with your vehicle unladen and the trailer laden.
– Do not make full use of the legal maximum speeds. This applies in particular to
downhill sections.
– Apply the brakes in good time.
– Keep a check on the coolant temperature gauge if the outside temperature is
high.
Distribution of weight
The distribution of the weight is very poor if your vehicle is unladen and the trailer
is laden. Maintain a particularly low speed if you cannot avoid driving with this
combination.
Driving speed
Do not drive faster than 80
km/h for safety reasons. This also applies for countries
in which higher speeds are allowed.
The fact that the driving stability of the vehicle + trailer combination reduces with
increasing speed means that the legally allowed speed should not be used when
there are unfavourable road, weather or wind conditions, particularly near acci-
dent black spots.
You must always reduce your speed immediately as soon as you detect even just
the slightest swaying of the trailer. On no account attempt to stop the trailer
from “swaying” by accelerating.
Apply the brakes in good time! If the trailer is fitted with a trailer brake, apply the
brakes gently at first and then brake firmly. This will avoid brake jolts resulting
from the trailer wheels locking. Shift down gears in good time before negotiating
a downhill section to allow the engine to also act as a brake.
Engine overheating
Please keep a check on the coolant temperature gauge if you have to negotiate a
lengthy slope in a low gear at a high engine speed when the outside temperature
is very high ⇒ page 11.
If the needle of the coolant temperature gauge moves into the right-hand area or
even the red area of the scale, reduce your speed immediately. Stop and switch
off the engine if the warning light in the instrument cluster begins flashing.
Wait a few minutes and check the level of coolant in the coolant expansion bottle
⇒ page 154, Inspecting the coolant level. Please refer to the following guidelines
⇒
page 23, Coolant temperature/ Coolant
quantity .
The coolant temperature can be reduced by switching on the heating.
Any increase in the cooling effect of the coolant fan through shifting down a gear
and increasing the engine speed is not possible since the fan speed is independ-
ent of the engine speed. One should also not drop a gear for this reason when
towing a trailer as long as the engine can manage the slope without any drop in
speed. 140

Engine oil Check engine oil level The dipstick indicates the level of oil in the engine.
Fig. 124 Dipstick
Checking the oil level
– Ensure that the vehicle is positioned on a level surface and the engine has
reached its operating temperature.
– Switch the engine off.
– Open the bonnet ⇒ in Working in the engine compartment on page 151.
– Wait a few minutes until the engine oil flows back into the oil sump. Take out
the dipstick.
– Wipe off the dipstick with a clean cloth and insert it again fully.
– Then withdraw the dipstick again and read off the oil level.

6 Oil level within range
a –
You must not top up the oil.
Oil level within range b –
You may top up the oil. It is possible that the oil level may then be within
range a after doing this. The optimum lies in the middle of the range
b .
Oil level within range c –
You must top up the oil ⇒ page 152. It is sufficient, once this is done, to keep
the oil level is within range b .
It is normal for the engine to consume oil. The oil consumption may be as much as
0.5 l/1 000 km depending on your style of driving and the conditions under which
you operate your vehicle. The oil consumption may be slightly higher than this
during the first 5 000 kilometres.
One should therefore check the oil level at regular intervals, preferably every time
after the fuel tank is filled or after driving for long stretches.
We recommend maintaining the oil level within the range b if the engine has
been operating at high loads, for example during a lengthy motorway trip during
the summer months, towing a trailer or negotiating a high mountain pass, but not
above this .
The warning light in the instrument cluster will indicate whether the oil level is
too low ⇒ page 23,
Engine oil . In this case, check the oil level as soon as
possible. Top up with an appropriate quantity of oil. CAUTION
● The oil level must on no account extend beyond the range A . Danger of dam-
aging the catalytic converter.
● Do not continue your journey if for some reason it is not possible under the
conditions prevailing to top up with oil. Switch the engine off and obtain profes-
sional assistance from a specialist garage, otherwise it could lead to severe en-
gine damage. Note

page 152. £152
Inspecting and Replenishing

CAUTION
One should contact a specialist garage as soon as possible if the source of over-
heating itself cannot be determined and removed, since there may be grave dam-
age to the engine.
Replenishing the coolant –
Switch the engine off.
– Allow the engine to cool down.
– Place a cloth over the cap of the coolant expansion reservoir ⇒ fig. 125 and un-
screw the cap carefully by turning it to the left ⇒ .
– Top up the coolant.
– Screw the cap tight until it is heard to lock.
The coolant which you use for replenishing the system, must comply with one
specific specification ⇒ page 153, Coolant. Do not use an alternative additive if the
specified coolant additive is not available in exceptional cases. Just top up the sys-
tem with water and as soon as possible arrange adjustment to correct the mixing
ratio of water and coolant additive again by a specialist garage.
Only use fresh coolant for topping up the system.
Do not fill up over the
“MAX” marking! Excess coolant which is heated up is forced
out of the cooling system through the pressure relief valve in the cap of the cool-
ant compensation bottle.
Wait until the engine has cooled down for a system which has suffered a major
loss of coolant before pouring in coolant. This is necessary to avoid engine dam-
age. WARNING
● The cooling system is pressurized! Do not open the cap of the coolant ex-
pansion bottle if the engine is still hot - risk of scalding!
● The coolant additive and thus all of the coolant is harmful to your health.
Avoid contact with the coolant. Coolant vapours are also harmful to the
health. It is important, therefore, to always safely store any coolant additive in
its original container out of the reach of children - risk of poisoning! WARNING (Continued)
● If any splashes of coolant get into your eyes, rinse out your eyes immedi-
ately with clear water and contact a doctor as soon as possible.
● You should also consult a doctor without delay if you have inadvertently
swallowed coolant. CAUTION
Do not continue your journey if for some reason it is not possible under the condi-
tions prevailing to top up with coolant. Switch the engine off and obtain profes-
sional assistance from a specialist garage, otherwise it could lead to severe en-
gine damage. For the sake of the environment
Do not re-use coolant if it is necessary to drain the coolant in the system. It should
be collected and disposed of in compliance with environmental protection regula-
tions.
Radiator fan The radiator fan may switch on suddenly.
The radiator fan is driven by an electric motor and controlled according to the
coolant temperature.
The radiator fan may continue running for up to 10 minutes after the engine has
been switched off - even if the ignition is also off. It may also switch on suddenly
after a certain time, if
● the coolant temperature has risen because of an accumulation of heat or
● the warm engine compartment is heated up additionally by strong sunlight. WARNING
You must therefore be aware when working in the engine compartment that
the fan may switch on suddenly - risk of injury! 155
