Downloaded from www.Manualslib.com manuals search engine Reducing idling
If the vehicle is fitted with the START - STOP system there is an automatic re-
duction of the idling. If the engine is stopped on vehicles without START-STOP
system, such as when waiting in a traffic jam, the fuel economy is already
greater after 30 - 40 s than the fuel quantity which is required for engine re-
start.
Avoid short distances
When driving a short distance of less than about 4 km, the engine cannot
reach its operating temperature. As long as the engine has not reached oper-
ating temperature, the fuel consumption is significantly higher than with the
engine hot.
Pay attention to the correct tyre inflation pressure being maintained
Further information » page 161.
Avoid unnecessary ballast
Per 100 kg of weight, consumption increases by about 0.3 l/100 km. At a speed of 100 - 120 km/h, a vehicle fitted with a roof rack cross member without a load
will use about 10 % more fuel than normal due to the increased aerodynamic
drag.
Saving electricity
Electrical consumers (e.g. seat heating, air conditioning and the like) should
only be turned on for as long as necessary.
Use the cooling system economically
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
interior has been strongly heated through the effect of direct sunlight in order
to allow the heated air to escape.
The cooling system should not be switched on if the windows are open.DriveGreen functionFig. 121

Avoiding damage to your vehicle

Driving Tips

Driving through water
113
This section of the manual contains important information on preventing dam-
age to the vehicle while driving.
Driving Tips
Only drive on such roads and in such terrain, which match the vehicle parame-
ters » page 192 , Technical data as well as your driving skills.
The driver is always responsible for deciding whether the vehicle can handle
travelling in the given terrain.WARNING■ Always adjust your driving to the current terrain and weather conditions.
Excessive speed or incorrect driving manoeuvres can cause damage to the
vehicle and lead to serious injuries.■
Combustible objects such as dry leaves or twigs caught under the base of
the vehicle could ignite on hot vehicle parts - risk of fire!
CAUTION
■ Pay attention to the ground clearance of the vehicle! When driving over ob-
jects which are larger than the ground clearance, the vehicle can get damaged.■
Any objects that get trapped under the vehicle floor must be removed as
soon as possible. These objects can damage the fuel lines, the brake system,
seals and other parts of the vehicle.
■
Drive slowly in unknown terrain and watch out for unexpected obstacles,
such as potholes, rocks, stumps, etc.
■
Check up on confusing sections of unpaved roads before travelling on them
and consider whether such travelling is possible without risk.
Driving through water
Fig. 122
Maximum permissible water lev-
el when driving through water
The following instructions must be observed if vehicle damage is to be avoided
when driving through water (e.g. flooded roads).
113Starting-off and driving
Downloaded from www.Manualslib.com manuals search engine During an intervention of the system, the warning light flashes in the instru-
ment cluster.
Anti-lock braking system (ABS)
Read and observe
on page 114 first.
ABS prevents the wheels locking when braking. Thereby, it helps the driver to
maintain control of the vehicle.
The intervention of the ABS is noticeable from the pulsating movements of
the brake pedal which is accompanied by noises.
When the ABS system is active, do not pump the brakes or lift off the brake
pedal.
Traction control (TCS)
Fig. 123
System button: Activating/deac-
tivating TCS
Read and observe on page 114 first.
TCS prevents the spinning of the wheels of the driven axle. TCS reduces the drive power transmitted to the wheels in the case of slipping wheels. Thereby,
for example, driving on road surfaces with low grip is made easier.
During a TCS intervention, the indicator light flashes in the instrument clus-
ter.
Activating/deactivating TCS
The activation or deactivation of TCS can be done, depending on equipment, in
one of the following ways.
› Infotainment
» Operating instructions Infotainment , chapter CAR - vehicle
settings .
› By briefly pressing the symbol key
» Fig. 123 .
Upon deactivation, in the instrument cluster the indicator light illuminates
and the display shows the following message.
Traction control (ASR) deactivated.
ASR OFF
Upon activation, in the instrument cluster the indicator turns
and the display
shows the following message.
Traction control (ASR) activated.
ASR ON
The TCS should normally always be enabled. The system should be deactivated
only in the following situations, for example.
› When driving with snow chains.
› When driving in deep snow or on a very loose surface.
› When “rocking a car free” when it has become stuck.
Electronic differential lock (EDL and XDS)
Read and observe
on page 114 first.
EDL
EDL prevents the turning of the respective wheel of the driven axle. EDL
brakes the spinning wheel, if necessary, and transmits the driving force to the
other driving wheel. Driving becomes easier on road surfaces with different
traction under each wheel of the driven axle.
EDL switches off automatically to avoid excessive heat generation on the
brake of the wheel being braked. Once the brakes have cooled down, there is
an automatic re-activation of EDL.
XDS
XDL is an extension to the electronic differential lock. XDL does not respond to
traction, but to the load relief of the inner front wheel of the driving axle dur-
ing fast cornering.
The automatic brake intervention on the brake of the wheel with reduced load
prevents the wheel from spinning. Thus, the traction is improved and the vehi-
cle can continue to follow the desired track.
Brake Assist (HBA)
Read and observe
on page 114 first.
HBA increases the braking effect and helps to shorten the braking distance.

The interval between the acoustic signals becomes shorter as the clearance is
reduced. A continuous tone sounds from a distance of approx. 30 cm - danger
area. From this moment on do not continue driving!

Activation
The activation of the system is initiated when the reverse gear is engaged, or
vehicles with the Variant 2, also by pressing the symbol key
» Fig. 127
.
This is confirmed by a short acoustic signal (the symbol in the button lights
up).
Deactivation
On vehicles with Version 1, the system can be deactivated by moving out of re-
verse gear.
For vehicles with Version 2, the system is deactivated by pressing the symbol
button or automatically at a speed over 10 km/h (the symbol
in the but-
ton goes out).
Displaying an error
If a warning signal sounds for about 3 seconds after activating the system and
there is no obstacle close to your car, this indicates a system fault. The fault is
also indicated by the symbol
flashing in the button. Seek help from a spe-
cialist garage.
Note
The system can only be activated with the symbol key at a speed of below
approx. 10 km / hr.
