8Safe driving
you and your passengers can achieve the greatest possible benefit from the
safety equipment fitted. This manual includes important warnings that you
and your passengers should note in order to reduce the risk of injury.
Safety is everyone's business!
Before setting off
The driver is responsible for the safety of the passengers
and the safe operation of the vehicle.
For your own safety and the safety of your passengers, always note
the following points before every trip:
– Make sure that the vehicle's lights and turn signals are working
properly.
– Check tyre pressure.
– Ensure that all windows provide a clear and good view of the
surroundings.
– Ensure that all luggage is correctly secured ⇒ page 16.
– Make sure that no objects can interfere with the pedals.
– Adjust front seat, head restraint and mirrors properly according
to your size.
– Ensure that the passenger in the central rear seat always has
the head restraint in the correct position for use.
– Instruct passengers to adjust the head restraints according to
their height. –
Protect children with appropriate child seats and properly ap-
plied seat belts ⇒ page 42.
– Assume the correct sitting position. Instruct your passengers al-
so to assume a proper sitting position. ⇒ page 10.
– Fasten your seat belt securely. Instruct your passengers also to
fasten their seat belts properly. ⇒ page 18.
What affects driving safety?
Driving safety is largely determined by your driving style
and the personal behaviour of all occupants. As a driver, you are responsible for yourself and your passengers.
When your concentration or driving safety is affected by any cir-
cumstance, you endanger yourself as well as others on the road
⇒
, for this reason:
– Always pay attention to traffic and do not get distracted by pas-
sengers or telephone calls.
– Never drive when your driving ability is impaired (e.g. by medi-
cation, alcohol, drugs).
– Observe traffic laws and speed limits.
– Always reduce your speed as appropriate for road, traffic and
weather conditions.
– When travelling long distances, take breaks regularly - at least
every two hours.
– If possible, avoid driving when you are tired or stressed.

68Cockpit
There is a fault in the ABS if:
● The warning lamp does not light up when the ignition is switched on.
● The warning lamp does not go out again after a few seconds
● The warning lamp lights up when the vehicle is moving
The vehicle can still be braked in the normal way, without the ABS function.
Take the vehicle to a specialised workshop as soon as possible. For further
information on the ABS go to ⇒ page 162.
If there is a fault in the ABS, the ESP* and the tyre pressure warning lamp
will also light up.
Brake system fault
If the ABS warning lamp lights up together with the brake warning lamp
, this indicates not only a fault in the ABS function, but also a possible
fault in the brake system ⇒
.
WARNING
● Before opening the bonnet, read and observe the warnings on
⇒ page 193, Working in the engine compartment.
● If the brake warning lamp should light up together with the ABS
warning lamp , stop the vehicle immediately and check the brake fluid
level in the reservoir ⇒ page 205, Brake fluid. If the fluid level has drop-
ped below the “MIN” mark you must not drive on. Risk of accident. Ob-
tain technical assistance.
● If the brake fluid level is correct, the fault in the brake system may
have been caused by a failure of the ABS system. This could cause the
rear wheels to lock quickly when you brake. This could cause the rear to
break away. Risk of skidding. Stop the vehicle and seek technical assis-
tance.
Differential lock fault (EDL)*
EDL operates along with the ABS in vehicles equipped with
an Electronic Stability Programme (ESP)*
A malfunction in the EDL is indicated by the ABS warning lamp . Take the
vehicle to a specialised workshop as soon as possible. For further informa-
tion on the EDL see ⇒ page 164, Electronic differential lock (EDL)*.
Traction control system (TCS)* /
The traction control system prevents the driven wheels from
spinning when the vehicle is accelerating
There are two warning lamps for the traction control system: and . Both
warning lamps light up together when the ignition is switched on and
should turn off after approximately 2 seconds. This is the time taken for the
function check.
The lamp has the following function:
● It flashes when the TCS is on, and the vehicle is moving.
If the system is deactivated or if it has any fault, the warning lamp will re-
main lit. It will also come on if a fault should occur in the ABS because the
TCS operates in conjunction with the ABS. For further information, see
⇒ page 161, Brakes
The lamp provides information about the disconnection status of the
system:
● It stays lit when the TCS is disconnected after pressing the TCS OFF
switch.
By pressing again, TCS function is reactivated and the warning lamp switch-
ed off.

Tyre pressure*
Fig. 40 Centre console:
tyre monitor system but-
ton
The tyre warning lamp 1)
compares wheel revolutions and with this informa-
tion, the diameter of each wheel using the ESP sensors. If the diameter of a
wheel changes, the tyre warning lamp lights up. The wheel diameter
changes when:
● Tyre pressure is insufficient.
● The tyre structure is damaged.
● The vehicle is unbalanced because of a load.
● The wheels of one axle are under more pressure (for example, driving
with a trailer or on extreme slopes).
● The vehicle is fitted with snow chains.
● The temporary spare wheel is fitted.
● The wheel on one axle is changed. Tyre pressure adjustment
Following the modification to tyre pressure or changing one or more wheels,
the button ⇒ fig. 40 must be kept pressed while the ignition is on until an
acoustic signal is heard.
If the wheels are under excessive load (for example, driving with a trailer or
heavy load), the tyre pressure must be increased to the recommended value
for a full load (see the sticker on the inside of the fuel flap). If the tyre moni-
tor system button is pressed down, the new tyre pressures are confirmed.
The tyre pressure warning lamp lights up
If the tyre pressure of a wheel is much lower than the value set by the driver,
then the tyre pressure warning lamp ⇒
will light up.
WARNING
● When the tyre pressure warning lamp lights up, reduce speed imme-
diately and avoid any sudden manoeuvre or braking. Stop when possible,
and check the tyre pressure and status.
● The driver is responsible for maintaining correct tyre pressures. For
this reason, tyre pressure must be regularly checked.
● Under certain circumstances (for example, when driving in a sports-
like manner, in winter conditions or on a dirt track) the tyre warning lamp
may light up or function incorrectly.
Note
If the battery is disconnected, the yellow warning lamp lights up after
turning the ignition on. This should turn off after a brief journey.

WARNING
● The risk of accident is higher if you drive too fast, if you do not keep
your distance to the vehicle in front, and when the road surface is slip-
pery or wet. The increased accident risk cannot be reduced by the brake
assist system.
● The brake assist system cannot defy the laws of physics. Slippery
and wet roads are dangerous even with the brake assist system! There-
fore, it is essential that you adjust your speed to suit the road and traffic
conditions. Do not let the extra safety features tempt you into taking any
risks when driving.
Anti-lock brake system and traction control
ABS Anti-lock brake system (ABS)
The anti-lock brake system prevents the wheels locking dur-
ing braking.
The anti-lock brake system (ABS) is an important part of the vehicle's active
safety system.
How the ABS works
If one of the wheels is turns too slowly in relation to the road speed, and is
close to locking, the system will reduce the braking pressure for this wheel.
The driver is made aware of this control process by a pulsating of the brake
pedal and audible noise. This is a deliberate warning to the driver that one
or more of the wheels is tending to lock and the ABS control function has
intervened. In this situation it is important to keep the brake pedal fully de-
pressed so the ABS can regulate the brake application. Do not “pump”. If you brake hard on a slippery road surface, the best possible control is re-
tained as the wheels do not lock.
However, ABS will not necessarily guarantee shorter braking distances in
all
conditions. The braking distance could even be longer if you brake on gravel
or on fresh snow covering a slippery surface.
WARNING
● The anti-lock brake system cannot defy the laws of physics. Slippery
and wet roads are dangerous even with ABS! If you notice that the ABS is
working (to counteract locked wheels under braking), you should reduce
speed immediately to suit the road and traffic conditions. Do not let the
extra safety features tempt you into taking any risks when driving.
● The effectiveness of ABS is also determined by the tyres fitted
⇒ page 209.
● If the running gear or brakes are modified, the effectiveness of the
ABS could be severely limited.
Traction control system (TCS)*
The traction control system prevents the drive wheels from
spinning when the vehicle is accelerating. The system al-
ways includes ABS
Description and operation of the traction control system during
acceleration (TCS)
TCS reduces engine power to help prevent the drive wheels of front-wheel
drive vehicles losing traction during acceleration. The system works in the
entire speed range in conjunction with ABS. If a malfunction occurs in the
ABS, the TCS will also be inoperative.

169
Driving and the environment
Drive anticipating the traffic situation
A vehicle uses most fuel when accelerating. When you anticipate the situa-
tion, you have to brake less often and, thus, accelerate less. If it is possible,
let the vehicle roll with a gear engaged, for example, if you see a red light
ahead. The braking effect achieved in this way helps to reduce the wear of
brakes and tyres; emissions and fuel consumption are reduced to zero (dis-
connection due to inertia).
Change gear early to save energy
An effective way of saving fuel is to change up quickly through the gears.
Running the engine at high rpm in the lower gears uses an unnecessary
amount of fuel.
Manual gearbox: Change from first to second gear as quickly as possible.
We recommend that, whenever possible, you change to a higher gear upon
reaching 2000 rpm. Follow the “recommended gear” indication that ap-
pears on the instrument panel ⇒ page 56.
Avoid driving at high speed
We advise you not to drive at the top speed permitted by the vehicle. Fuel
consumption, exhaust emissions and noise levels all increase very rapidly
at higher speeds. Driving at moderate speeds will help to save fuel.
Avoid idling
It is worthwhile switching off the engine when waiting in a traffic jam, at lev-
el crossings or at traffic lights with a long red phase. The fuel saved after
only 30 - 40 seconds is greater than the amount of fuel needed to restart
the engine.
The engine takes a long time to warm up when it is idling. Mechanical wear
and pollutant emissions are also especially high during this initial warm-up
phase. It is therefore best to drive off immediately after starting the engine.
Avoid running the engine at high speed.
Periodic maintenance
Periodic maintenance work guarantees that, before beginning a journey,
you will not consume more than the required amount of fuel. A well-serviced engine gives you the benefit of
improved fuel efficiency as well as maxi-
mum reliability and an enhanced resale value.
A badly serviced engine can consume up to 10% more fuel than necessary.
Avoid short journeys
To reduce the consumption and emission of polluting gases, the engine and
the exhaust filtration systems should reach the optimum service tempera-
ture.
With the engine cold, fuel consumption is proportionally higher. The engine
does not warm up and fuel consumption does not normalise until having
driven approximately four kilometres. This is why we recommend avoiding
short trips whenever possible.
Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an adequate pressure saves fuel. If
the tyre pressure is just one bar too low, fuel consumption can increase by
as much as 5%. Due to the greater rolling resistance, under-inflation also
increases tyre wear and impairs handling.
The tyre pressures should always be checked when the tyres are cold.
Do not use winter tyres all year round as they increase fuel consumption by
up to 10%.
Avoid unnecessary weight
Every kilo of extra weight will put up the fuel consumption, so it is worth
checking the luggage compartment occasionally to make sure that no un-
necessary loads are being transported.
A roof rack is often left in place for the sake of convenience, even when it is
no longer needed. At a speed of 100-120 km/h your vehicle will use about
12% more fuel as a result of the extra wind resistance caused by the roof
rack even when it is not in use.

172Driving and the environment
The figures for trailer weights and drawbar loads that are given on the data
plate of the towing bracket are for certification purposes only. The correct
figures for your specific model, which may be lower than these figures for
the towing bracket, are given in the vehicle documents or in ⇒ chapter Tech-
nical Data.
Distributing the load
Distribute loads in the trailer so that heavy objects are as near to the axle as
possible. Loads carried in the trailer must be secured to prevent them mov-
ing.
Tyre pressure
Set tyre pressure to the maximum permissible pressure shown on the stick-
er on the inside of the fuel tank flap. Set the tyre pressure of the trailer tyres
in accordance with the trailer manufacturer's recommendations.
Exterior mirrors
Check whether you can see enough of the road behind the trailer with the
standard mirrors. If this is not the case, you should have additional mirrors
fitted. Both exterior mirrors should be mounted on hinged extension brack-
ets. Adjust the mirrors to give sufficient vision to the rear.
WARNING
Never transport people in a trailer. This could result in fatal accidents.
Note
● Towing a trailer places additional demands on the vehicle. We recom-
mend additional services between the normal inspection intervals if the ve-
hicle is used frequently for towing a trailer.
● Find out whether special regulations apply to towing a trailer in your
country. Ball coupling of towing bracket*
The ball coupling is provided with instructions on fitting and removing the
ball coupling of the towing bracket.
WARNING
The towing bracket ball coupling must be stored securely in the luggage
compartment to prevent them being flung through the vehicle and caus-
ing injury.
Note
● By law, the ball coupling must be removed if a trailer is not being towed
and it obscures the number plate.
Driving tips
Driving with a trailer always requires extra care. Weight distribution
The weight distribution of a loaded trailer with an unladen vehicle is very
unfavourable. However, if this cannot be avoided, drive extra slowly to allow
for the unbalanced weight distribution.
Speed
The stability of the vehicle and trailer is reduced with increasing speed. For
this reason, it is advisable not to drive at the maximum permissible speed
in an unfavourable road, weather or wind conditions. This applies especially
when driving downhill.
You should always reduce speed immediately if the trailer shows the slight-
est sign of snaking. Never try to stop the “snaking” by increasing speed.
