Driving Tips
Only drive on roads and terrain that correspond to the vehicle parame-
ters » page 173 , Technical data .
The driver is always responsible for deciding whether the vehicle can cope
with the conditions and the terrain.
WARNING■ Adjust the speed and driving style to the current visibility, weather, road
and traffic conditions. Too high a speed or an erroneous manoeuvre may
cause serious injury and damage to the vehicle.■
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 items can cause damage to the vehicle (e.g. to parts of
the fuel or brake system).
Driving through water
Fig. 124
Maximum permissible water lev-
el when driving through water
99Starting-off and driving
The following instructions must be observed if vehicle damage is to be avoided
when driving through water (e.g. flooded roads).›
Therefore, always determine the depth of the water before driving through
water. The water level must not go above the web of the lower beam
» Fig. 124 .
›
Drive at no more than walking pace, otherwise a wave may form in front of
the vehicle, which could cause the water to enter into the vehicle’s systems
(e.g. the air intake system for the engine).
›
Never stop in the water, do not reverse and do not switch the engine off.
CAUTION
■ If water gets into the vehicle’s systems (e.g. the air intake system for the en-
gine) it can cause serious damage to the vehicle!■
Oncoming vehicles can generate water waves which can exceed the permis-
sible water level for your vehicle.
■
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.
Assist systems
General information
Introduction
This chapter contains information on the following subjects:
Radar sensor
100WARNING■ The assistance systems only serve to support and do not relieve the driv-
er of the responsibility for driving the vehicle.■
The increased safety provision, as well as the increased occupant protec-
tion provided by the assistance systems must not tempt you to take risks -
risk of 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 enable, disable or set the assistance systems so that you have the
car fully under control in every traffic situation - risk of accident!
Radar sensor
Fig. 125
Installation location of the radar
sensor
Read and observe on page 100 first.
The radar sensor » Fig. 125 (hereinafter on referred to as sensor) uses electro-
magnetic waves to capture the traffic situation ahead of the vehicle.
100Driving
The sensor is part of the ACC» page 110 and Front Assist » page 114systems.
The sensor function may be impaired in the events of one of the following. ▶ The sensor cover is soiled (e.g. with mud, snow etc.).
▶ The area in front of and around the sensor cover is obscured (e.g. by labels,
auxiliary headlights etc.).
▶ When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
If the sensor is covered or dirty, the corresponding message appears in the in-
strument cluster display for the ACC system » page 114, Malfunctions or Front
Assist system » page 116, Malfunctions .WARNING■
If you suspect that the sensor is damaged, deactivate the ACC system and
Front Assist system » page 111, » page 116 . Have the sensor checked by a
specialist garage.■
A collision or damage in the front or lower area of the vehicle could affect
the sensor function - there is risk of accident! Have the sensor checked by
a specialist garage.
■
Do not cover the area in front of and around the sensor cover. This can
lead to impaired function of the sensor - risk of accidents!
CAUTION
Remove the snow with a brush and the ice with a solvent-free de-icer.

The brake and stabilization systems are automatically activated each time the
ignition is switched on, unless otherwise indicated.
The error display is in Chapter » page 28, Warning lights .WARNINGThe general information relating to the use of assistance systems must be
observed » page 100, in section Introduction .
Stability Control (ESC)
Read and observe
on page 101 first.
The ESC improves vehicle stability when driving at the limit (e.g. if the vehiclestarts to skid) by braking individual wheels to maintain the desired direction.
If there is a TCS intervention, the indicator light flashes in the instrument
cluster.
Anti-lock braking system (ABS)
Read and observe
on page 101 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.
Engine drag torque control (MSR)
Read and observe
on page 101 first.
MSR counteracts the tendency of the drive wheels to lock during downshifts
or sudden deceleration (e.g. on icy or an otherwise slippery road surface).
If the drive wheels should lock, then the engine speed is automatically in-
creased. This reduces the braking effect of the engine and the wheels can ro-
tate freely again.
101Assist systems
Traction control (TCS)Fig. 126
Key for the TCS system
Read and observe on page 101 first.
TCS prevents the spinning of the wheels of the driven axle. TCS reduces thedrive 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.
The deactivation/activation of TCS can be carried out, depending on equip-
ment, in one of the following ways. ▶ Infotainment » Owner's Manual Infotainment .
▶ By pressing the
» Fig. 126 button.
During deactivation the warning light lights up in the instrument cluster
and
an appropriate message is displayed in the instrument cluster.
During activation extinguished the warning light
is and an appropriate mes-
sage is displayed in the instrument cluster.
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 101 first.
EDL prevents the turning of the respective wheel of the driven axle. EDL
brakes a spinning wheel if required and transfers the drive power force to the
other drive wheel. Driving becomes easier on road surfaces with different trac-
tion 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 is an extension to the electronic differential lock (EDL). XDS does not re-
spond to the relieved inner curve wheel of the driven axle in the case of fast
cornering.
By applying braking force to the relieved wheel, spinning is prevented by the
XDS. This has a positive effect on the driving stability and steerability of the
vehicle.
Brake Assist (HBA)
Read and observe
on page 101 first.
HBA increases the braking effect and helps to shorten the braking distance.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 101 first.
When moving off on a gradient, HHC allows you to move your foot from thebrake pedal to the accelerator pedal without the vehicle rolling downhill.
The vehicle is braked by the system for about 2 seconds after releasing the
brake pedal.
The HHC is active on gradients upwards of 5 % if the driver door is closed. HHC
is always only active on slopes pulling away forwards or in reverse.
102Driving
Distance of the orientation lines behind the vehicle » Fig. 133

The Adaptive Cruise Control (hereinafter referred to as ACC) maintains the set
speed or the distance to the vehicle ahead without the accelerator or brake
pedal being pressed.
The front of the vehicle and the distance to the vehicle ahead is monitored by
a radar sensor » page 100.
The state in which the ACC maintains the speed or the proximity is described
as control from here on.
WARNING■
The general information relating to the use of assistance systems must
be observed » page 100, in section Introduction .■
The driver must always be ready to take over the operation of the accel-
erator and brake pedal.
■
The ACC does not react when approaching a stationary obstacle, such as
traffic jams, vehicle breakdowns or vehicles waiting at a traffic light.
■
The ACC does not respond to crossing or oncoming objects.
■
If the ACC does not decelerate fast enough, immediately apply the vehi-
cle's foot brake.
WARNINGFor safety reasons, do not use the ACC under the following conditions.■When driving in turning lanes, motorway exits or construction sites, to
avoid an unwanted acceleration to the stored speed.■
When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
■
When road conditions are poor (e.g. ice, slippery road, gravel, dirt road).
■
Driving into “sharp” corners or in steep gradients / on steep inclines.
■
When driving through places where metal objects (such as metal build-
ings, railway tracks, etc.) can be found.
■
When driving through very divided and enclosed spaces (such as large-ca-
pacity garages, car ferries, tunnels and the like.).
Note
■ The ACC is designed primarily for use on motorways.■The ACC reduces the speed by automatically releasing the accelerator or by
means of a braking procedure as appropriate. If the brakes are used for an au-
tomatic speed reduction at any moments, then the brake light illuminates.■
In case of failure of more than one brake light on the vehicle or on the con-
nected trailer, the ACC becomes unavailable.
■
The control automatically cancels the engagement of the brake supportive
assistance systems (e.g. ESC) or when the maximum permitted engine speed is
exceeded.

The ACC allows a speed of 30-160 km/h to be set or a distance to the preced-
ing vehicle to be very short of very long to be set.
The ACC adjusts the set speed with respect to the detected vehicle ahead,
thus maintaining the selected proximity.
The ACC can detect a vehicle that is up to approx. 120 m ahead using the radar
sensor.

Note to reduce speed
If the delay of the ACC is insufficient in relation to the vehicle in front, the
warning light lights up in the instrument cluster and the display shows a
message to engage the brake pedal.
1234NoteSome ACC notifications in the display of the instrument cluster may be hidden
by notifications for other functions. An ACC notification automatically appears
for a brief moment when there is a change in status of the ACC.
Automatic stop-start
Read and observe
on page 110 first.
Vehicles with an automatic transmission can decelerate to a complete stop
and start moving again using the ACC.
Decelerate to a complete stop
If a vehicle ahead decelerates to a standstill, the ACC will also decelerate your
vehicle to a complete stop.
Starting to drive again after a holding period
As soon as the vehicle ahead starts moving again after a holding period, your
vehicle will also move and the speed will continue to be controlled. Control is
automatically disconnected in case of longer holding periods.
