Traction control system (TCS) The traction control system prevents
the driven wheels from spinning
when accelerating.General The TCS makes it much easier, and sometimes at all possible, to start off, accelerate and climb a steep hill when the conditio
ns of the road surface are unfavourable.
Operating principle The TCS switches on automatically when th
e engine is started and then conducts a
self-test. The system monitors the speeds of the driven wheels with the aid of the ABS sensors. If the wheels are spinning, the force transmitted to the road surface is automatically adapted by redu
cing the engine speed. Th
is occurs at all speeds.
The TCS operates in combination with the ABS
⇒page 135, “Antilock brake system
(ABS)*”. The TCS will not function if a fault exists in the ABS system. The TCS warning light
⇒page 33 lights up in the instrument cluster when there is a
fault on the TCS. Switching off You can switch the TCS off and on again
as you wish by pressing the button
⇒ fig. 140
. The TCS warning light
⇒page 33 lights up in the instrument cluster
when the TCS is switched off.
The TCS should normally always be switched on. It may be good practice in certain exceptional cases, such as when you wish
to have wheel slip, to switch off the
system. Examples:•
when driving with snow chains
•
when driving in deep snow or on a loose surface
•
when it is necessary to rock a vehicle when it has become stuck.
then you should switch on the TCS again.
WARNING
You should always adjust your style of driving to the conditions of the road surface and the traffic situation. The increased safety offered must not tempt you to take greater risks than otherwise - risk of an accident!
Note
•
All four wheels must be fitted with the same tyres in order to achieve problem-
free operation of the TCS. Differing rolling circumferences of the tyres can lead to an undesirable reduction in the engine output.•
Changes to vehicle (e.g. on engine, on
the brakes, on chassis or another combi-
nation of tyres and wheels) can in
fluence the function of the TCS
⇒page 179,
“Accessories, changes and replacement of parts”.BrakesWhat has a negative effect on braking efficiency?Wear-and-tear Wear-and-tear to the brake pads is greatly dependent on the operating conditions of the vehicle and your style of driving. Particularly if you drive a great deal in towns and over short distances or if you adopt a sporty style of driving, it may be neces- sary to have the thickness of the brake
pads inspected at a specialist garage
between the service inspections.

Check engine oil level The dipstick indicates the level of oil in the engine.Checking the oil level – Ensure that the vehicle is positioned on a level surface. – Switch the engine off.– Open the bonnet
⇒
in “Working in the engine compartment” on
page 160.
– Wait a few minutes and pull out the oil dipstick . – Wipe off the dipstick with a clea
n cloth and insert it again fully.
– Then withdraw the dipstick ag
ain and read off the oil level.
Oil level within range – You must
not
top up the oil.
Oil level within range – You
may
top up the oil. It is possible that the oil level may then be
within range after doing this.
Oil level within range –You
must
top up the oil
⇒
page 163. It is sufficient, once this is done,
to keep the oil level within range .
It is normal for the engine to consume oi
l. 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 consumpt
ion 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 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 31. 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 ex
tend beyond the range . Danger of
damaging the cata
lytic converter.
•
Do not continue your journey
if for some reason it is not possible under the
conditions prev
ailing to top up with oil.
Switch the engine off
and obtain profes-
sional assistance from a specialist garage, otherwise it could lead to severe engine damage.Replenishing engine oil– Inspecting the engine oil level

The coolant expansion bottle is loca
ted in the engine compartment on
the right. – Switch the engine off. – Open the bonnet
⇒
in “Working in the engine compartment” on
page 160.
– Check the level of coolant in the coolant expansion bottle
⇒
page 165, fig. 154
. When the engine is cold, the coolant level must
lie between the and markings. When the engine is warm, the level may also lie slightly above the hatched part.
If the coolant level in the reservoir is too low, this is indicated by the warning light in the instrument cluster
⇒page 30. We nevertheless recommend inspecting
the coolant level directly at th
e reservoir from time to time.
Loss of coolant A loss of coolant is first and foremost an
indication of a leak
in the system. You
should not merely top up the coolant in the reservoir. It is also important to have the cooling system inspected without delay by a specialist garage. Losses can only occur through the pressure
relief in the cap of the coolant expan-
sion bottle which is completely free of leak
s if the coolant boils as a result of over-
heating and is forced out of the cooling system.
WARNING
Read and observe the warning notes
⇒page 160, “Working in the engine
compartment” before working in the engine compartment.
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
damage 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
⇒
page 165, fig. 154
and unscrew 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 165, “Coolant”. Do not use an alternative additive if
the coolant additive G12 PLUS - PLUS is not av
ailable in exceptional cases. Just top
up the system 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 top up the fluid above the hatched
part! Excess coolant which is heated up
is forced out of the cooling system through the pressure relief valve in the cap of the coolant 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 damage.
WARNING
•
The cooling system is pressurized! Do not open the cap of the coolant
expansion 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!•
If any splashes of coolant get into yo
ur 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 conditions prevailing to top up with coolant. Switch the engine off
and obtain
professional assistance from a specialist garage, otherwise it could lead to severe engine 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 comp
liance with environmental protection
regulations.Radiator fan The radiator fan may switch on suddenly.The radiator fan is driven by an electr
ic motor and controlled according to the
coolant temperature. The radiator fan may continue running fo
r 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 beca
use of an accumulation of heat or
•
the warm engine compartment is heated
up additionally by
strong sunlight.
WARNING
You must therefore be aware when work
ing in the engine compartment that
the fan may switch on suddenly - risk of injury!
Brake fluidInspecting the brake fluid levelThe brake fluid reservoir is located on the left of the engine compartment. The brake fluid reservoir on right-hand steering models is positioned on the other side of the engine compartment. – Switch the engine off.– Open the bonnet
⇒
in “Working in the engine compartment” on
page 160.
– Inspect the brake fluid level in the reservoir
⇒
fig. 155
. The level must
be between the “MIN” and “MAX” markings.
A slight drop in the fluid level results when driving due to normal wear-and-tear and automatic adjustment of the br
ake pads, and is perfectly normal.
There may be an indication of a leak in the brake system, however, if the fluid level drops significantly within a short time or if it drops below the “MIN” marking. A situ- ation where the brake fluid level is too low is indicated by the warning light
lighting up in the instrument cluster
⇒page 34. In this case
stop immediately and
do not drive any further! Obtain professional assistance.
