The selector lever is locked in the P and N modes to prevent the forwards trav-
el mode from being selected accidentally and setting the vehicle in motion.
The selector lever is locked only when the vehicle is stationary and at speeds
up to 5 km/h.
The selector lever lock is indicated by the illumination of the warning light.
The selector lever is not locked when quickly moving across the position N
(e.g. from R to D/S ). This, for example, helps to rock out a vehicle that is stuck,
e.g. in a bank of snow. The selector lever lock will engage if the lever is in posi-
tion N for more than approx. 2 seconds without the brake pedal being de-
pressed.

Defective selector lever lock
If the selector lever lock is defective or its power supply is interrupted (e.g. dis-
charged vehicle battery, faulty fuse), the selector lever can no longer be moved
out of position P in the normal manner and the vehicle can no longer be driven.
The selector lever must be emergency released » page 179.

Note
■
It may be advantageous to use manual gear shifting when driving downhill,
for example. Shifting to a lower gear reduces the load on the brakes and hence
brake wear » page 106.■
When accelerating, the gearbox automatically shifts up into the higher gear
just before the maximum permissible engine speed is reached.
■
If a lower gear is selected, the gearbox does not shift down until there is no
risk of the engine overrevving.

of the vehicle – there is a risk of an accident.
Running-in and economical driving
Introduction
This chapter contains information on the following subjects:
Running-in
111
Tips for economical driving
111
DriveGreen function
112The 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 not to use
a trailer.
In the range of 1,000 to 1,500 kilometres, the engine load can be increased up
to the maximum permitted engine speed.
New tyres
New tyres have to be “run in” since they do not offer optimal grip at first.
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.
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.
Change gear in an energy saving and timely manner
Observe the recommended gear » page 39.
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.
111Starting-off and driving
Page 115 of 216

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

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

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
Page 117 of 216

Downloaded from www.Manualslib.com manuals search engine ›Therefore, always determine the depth of the water before driving through
water.
The water level must not reach above the web of the lower sill » Fig. 122.›
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 intake 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 risk
of serious damage to the engine parts!■
When driving through water, some vehicle parts such as chassis, electrics or
transmissions may 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 water.
■
Do not drive through salt water, as the salt can cause corrosion. A vehicle
coming into contact with salt water is to be thoroughly rinsed with fresh wa-
ter.

This chapter describes the functions of the brake and stabilization systems.
The error display is in Chapter » page 31, Warning lights .
The brake and stabilization systems are automatically activated each time the
ignition is switched on, unless otherwise indicated.
WARNING■ A lack of fuel can cause irregular engine running or cause the engine to
shut down. The brake assist systems could then fail to function – risk of ac-
cident!■
The increased safety provided by the brake assist systems must not
tempt you to take safety risks – risk of accident!
■
Adjust the speed and driving style to the current visibility, weather, road
and traffic conditions.
Stability Control (ESC)
Read and observe
on page 114 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.
114Driving
Page 118 of 216

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.
115Assist systems
Page 119 of 216

Downloaded from www.Manualslib.com manuals search engine The HBA is activated by very rapid depression of the brake pedal. To achieve
the shortest possible braking distance, the brake pedal must be applied firmly
until the vehicle has come to a complete standstill.
HBA is automatically switched off when the brake pedal is released.
Hill Start Assist (HHC)
Read and observe
on page 114 first.
HHC allows you to move your foot from the brake pedal to the accelerator ped-al without having to use the handbrake when pulling away on a gradient.
The system holds the brake pressure produced by the activation of the brake
pedal for approx. 2 seconds after the brake pedal is released.
HHC is active on slopes of >5 % when the driver door is closed. HHC is always
only active on slopes pulling away forwards or in reverse.
Multi collision brake (MCB)
Read and observe
on page 114 first.
The MCB helps to decrease speed after a collision through automatic brakinginterventions and to stabilize the vehicle. This reduces the risk of a subse-
quent crash due to uncontrolled vehicle movement.
The automatic brake interventions can take place only if the following condi-
tions are met.
There was a front, side and rear-end collision of a certain severity.
The impact speed was higher than approx. 10 km/h.
The brakes, the ESL and other required electrical systems remain function-
al after impact.
The accelerator pedal is not actuated.

The parking aid (hereinafter referred to only as system) draws attention via
acoustic signals or the Infotainment display when manoeuvring around obsta-
cles in the vicinity of the vehicle.
WARNING■ The system only serves as an assistance and does not relieve the driver
of the responsibility for the vehicle operation.■
Moving persons or objects may not be recognised 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 to be not 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. in front or behind your vehi-
cle. Such obstacles may not be recognised by the system sensors.
CAUTION
■ Keep the system sensors » Fig. 124 on page 117 clean, snow-and ice-free
and do not cover with any objects of any kind, otherwise the system function-
ing may be impaired.■
Under adverse weather conditions (heavy rain, water vapour, very low or
high temperatures etc.) system function may be limited “incorrect obstacle de- tection ”.
■
Additionally installed accessories such as e.g. bicycle carriers can impair the
system function.
