The gearbox shifts down one or more gears depending on the vehicle speed
and engine speed, and the vehicle accelerates.
The gearbox does not shift up into the highest gear until the engine has
reached its maximum revolutions for this gear range.WARNINGRapid acceleration, particularly on slippery roads, can lead to loss of vehicle
control – risk of accident!
Running-in and economical driving
Introduction
This chapter contains information on the following subjects:
Running-in
83
Tips for economical driving
83
The fuel consumption, degree of pollution and vehicle wear depend on driving
style, road condition, weather conditions and the like.
Running-in
Driving in the engine
The engine has to be run in during the first 1 500 kilometres. During this peri-
od, the driving style decides on the quality of the driving-in process.
During the first 1 000 km we recommend not driving faster than 3/4 of the
maximum permissible engine speed, not to drive at full throttle and to dis-
pense with the trailer.
In the area of 1,000 to 1,500 kilometres the engine load can be increased up
to the maximum permitted engine speed.
New tyres
New tyres must firstly be “run in” since they do not offer optimal grip at first.
Therefore, drive especially carefully for the first 500 km or so.
New brake pads
New brake pads have to first “grind in” because these do not initially have the
best possible braking effect.
Therefore, drive especially carefully for the first 200 km or so.
Tips for economical driving
To achieve the lowest possible fuel consumption, the following instructions
must be observed.
Looking ahead when driving
Avoid unnecessary acceleration and braking.
Switch in an energy saving and timely manner Observe the recommended gear » page 30.
Avoid full throttle and high speeds
Fuel consumption can be reduced by half if only three-quarters of the possible
top speed of your vehicle is used.
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 117.
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
Only turn on electrical consumers (e.g. seat, window and mirror heating and
similar) 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. 83Starting-off and Driving

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 on if the windows are open.
Avoiding damage to your vehicle

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 142 , 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 waterFig. 96
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).
›
Therefore determine the depth of the water before driving through bodies of
water.
The water level must not reach above the web of the lower beam » Fig. 96.
›
Do not drive any faster than at a walking speed.
At a higher speed, a water wave can form in front of the vehicle, which can
cause water to penetrate into the engine's air induction system or other parts
of the vehicle.
›
Never stop in the water, do not reverse and do not switch the engine off.
CAUTION
■ Should water penetrate into the intake system of the engine, there is a
threat of serious damage being incurred by the engine parts!■
When driving through water, some vehicle parts such as chassis, electrics or
transmission can be severely damaged.
■
Oncoming vehicles can generate water waves which can exceed the permis-
sible water level for your vehicle.
■
Potholes, mud or rocks can be hidden under the water, making it difficult or
impossible to drive through the body of water.
■
Do not drive through salt water, as the salt can cause corrosion. An vehicle
coming into contact with salt water is to be thoroughly rinsed with fresh wa-
ter.

Assist systems
General information
Introduction
WARNINGThe following general instructions regarding the use of assistance systems
must be observed.■
The assistance systems serve merely to support the driver and do not re-
lieve the driver of responsibility for the operation of the vehicle.
■
The increased safety as well as the increased occupant protection offered
by the assistance systems must not tempt you to take safety risks - there
is a risk of an accident!
■
Adjust the speed and driving style to the current visibility, weather, road
and traffic conditions.
■
The assistance systems have physical and system-related limitations. For
this reason, the driver may experience some undesired or delayed system
responses in certain situations. You should therefore always be alert and
ready to intervene!
■
Only activate, deactivate and set the assistance systems to keep you fully
in control of the vehicle in every traffic situation - otherwise there is a risk
of an accident!
Braking and stabilisation systems

Electronic Differential Lock (EDL)
86
Brake Assist (HBA)

This chapter describes the functions of the brake and stabilization systems.
The error display is in Chapter » page 34, Warning lights .
The brake and stabilisation systems are automatically activated each time the
ignition is switched on, unless otherwise indicated.
WARNINGThe general information relating to the use of assistance systems must be
observed » page 85, in section Introduction .
Stability Control (ESC)
Read and observe
on page 85 first.
The ESC improves vehicle stability in dynamic driving situations, such as whenthe vehicle starts to skid.
The ESC monitors whether the desired direction of the current vehicle motion
is occurring. In case of any deviation (e.g. oversteer), the ESC automatically
brakes individual wheels to maintain the desired direction.
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 85 first.
ABS prevents the wheels locking when braking. Thus helping 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 brake periodically or reduce the pres-
sure on the brake pedal.
Traction control (TCS)
Read and observe
on page 85 first.
TCS prevents the spinning of the wheels on the drive axle. TCS reduces the
drive power transmitted to the wheels that are spinning Thus, for example,
driving on road surfaces with low grip is made easier.
If there is a TCS intervention, the warning light flashes in the instrument
cluster.
85Assist systems

Electronic Differential Lock (EDL)Read and observe
on page 85 first.
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.
The EDL switches off automatically in order 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.
Brake Assist (HBA)
Read and observe
on page 85 first.
HBA increases the braking effect and helps to shorten the braking distance.The HBA is activated by very quick operation of the brake pedal. In order to
achieve the shortest possible braking distance, the brake pedal must be ap-
plied firmly until the vehicle has come to a standstill.
The HBA function is automatically switched off when the brake pedal is re-
leased.
Hill Start Assist (HHC)
Read and observe
on page 85 first.
When driving on slopes, HHC allows you to move your foot from the brake ped-al to the accelerator pedal without having to use the handbrake.
The system holds the brake pressure produced by the activation of the brake pedal for approx. 2 seconds after the brake pedal is released.
The HHC is active as of a 5 % slope, if the driver door is closed. HHC is always
only active on slopes when in forward or reverse start off.

The parking aid (hereinafter referred to as: the system) draws attention to any
obstacles via audible signals and a display in the Move & Fun multifunction de-
vice screen when manoeuvring in the vicinity of the vehicle » page 87, Visual
parking system .
WARNING■
The general information relating to the use of assistance systems must
be observed » page 85, in section Introduction .■
Moving persons or objects may not be recognized by the system sensors.
■
Under certain circumstances, surfaces of certain objects and types of
clothing cannot reflect the system signals. For this reason, such people or
objects may not be recognised by the system sensors.
■
External noise sources may affect the signals of the system sensors. Un-
der adverse conditions, this may cause objects or people not to be recog-
nised by the system.
■
Before reversing, you should make sure that there are no small obstacles,
such as rocks, thin posts, trailer drawbars etc. behind your vehicle. Such ob-
stacles may not be recognised by the system sensors.
CAUTION
■ Keep the system sensors clean, snow-and ice-free and do not cover with any
objects of any kind, otherwise the system functioning may be impaired.■
Under adverse weather conditions (heavy rain, water vapour, very low or
high temperatures etc.), the system function may be limited - “incorrect recog-
nition of obstacle”.
■
Additionally installed accessories such as e.g. bicycle carriers can impair the
system function.

City Safe Drive (hereinafter referred to as: the system) monitors the traffic sit-
uation ahead of the vehicle. If the system detects a risk of collision with an ob-
stacle ahead of the vehicle, then automatic braking is applied. The risk of a col-
lision is thus reduced and the consequences of an impact are minimized.
WARNING■ The general information relating to the use of assistance systems must
be observed » page 85, in section Introduction .■
The system does not respond to crossing or oncoming objects.
CAUTION
The system can slow down the vehicle to a standstill. If the vehicle continues
to roll forward after stopping, then it should be stopped with the footbrake.OperationFig. 100

.
The system interventions take place when a risk of collision is detected as fol-
lows.
▶ The brake system is prepared for an emergency stop.
▶ If the driver fails to respond to a detected danger, an automatic braking ac-
tion is performed.
The system is ready to intervene automatically in the following conditions. The engine is running.
The system is activated.
The travel speed is about 5-30 km/h.
