Automatic deactivation
In certain situations, the Auto Start/Stop func‐
tion is deactivated automatically in the interest
of safety, for example if the driver's absence is
detected.
Malfunction The indicator lamp lights up. The au‐
tomatic engine start/stop function no
longer switches of the engine auto‐
matically.A message appears on the Control
Display. It is possible to continue driving. Have
the system checked.
Handbrake
The concept
The handbrake is primarily intended to prevent
the vehicle from rolling while parked; it brakes
the rear wheels.
Indicator lamp
The indicator lamp lights up and an
acoustic signal sounds when driving
away. The handbrake is still set.
Setting
The lever engages automatically.
Releasing
Pull up slightly, press the button, and lower the
lever.
Notes Using the handbrake while driving
If it should become necessary to use the
handbrake while driving, do not pull the hand‐
brake too forcefully. Keep the button on the
handbrake lever pressed at all times.
Excessive application of the handbrake can
block the rear wheels and lead to fishtailing of
the vehicle.◀
To prevent corrosion and uneven brake action,
lightly apply the handbrake from time to time
when coasting, traffic conditions permitting.
The brake lamps do not light up when the hand‐
brake is pulled.

Driving stability control systemsVehicle equipment
This chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series.Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and sys‐
tems.
Antilock Brake System ABS
ABS prevents locking of the wheels during brak‐
ing.
The vehicle remains steerable even during full
brake applications, thus increasing active
safety.
ABS is operational every time you start the en‐
gine.
Electronic brake-force
distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
Brake assistant
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost. It thus helps to achieve the shortest
possible braking distance during full braking.
This system utilizes all of the benefits provided
by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.Dynamic Stability Control
DSC
The concept
DSC prevents traction loss in the driving wheels
when driving away and accelerating.
DSC also recognizes unstable vehicle condi‐
tions, such as fishtailing or nose-diving. Subject
to physical limits, DSC helps to keep the vehicle
on a steady course by reducing engine speed
and by applying brakes to the individual wheels.
Adjust your driving style to the situation
An appropriate driving style is always the
responsibility of the driver.
The laws of physics cannot be repealed, even
with DSC.
Do not reduce the additional safety margin with
a risky driving style, as otherwise there is a risk
of an accident.◀
Deactivating DSC: DSC OFF
When DSC is deactivated, driving stability is re‐
duced during acceleration and when driving in
bends.
To increase vehicle stability, activate DSC again
as soon as possible.
Deactivating DSC
Press and hold the button, but not lon‐
ger than approx. 10 seconds, until the

The system stores and maintains the speed.
Accelerating using the lever
Accelerating slightly:
Press the lever to the resistance point, arrow 1,
until the desired speed is reached.
Accelerating significantly:
Press the lever beyond the resistance point, ar‐
row 1, until the desired speed is reached.
The vehicle accelerates without pressure on the
accelerator pedal. The system stores and main‐
tains the speed.
Decreasing speed
Repeatedly pull the lever to the resistance point
or beyond, arrow 2, until the desired speed is
displayed.▷Each time the lever is pulled to the resist‐
ance point, the desired speed is decreased
by approx. 1 mph/1 km/h.▷Each time the lever is pulled beyond the re‐
sistance point, the desired speed is reduced
by up to 5 mph/10 km/h until the minimum
speed of 20 mph/30 km/h is achieved.
The system stores and maintains the speed.
Deactivating cruise control
Push the lever upwards or downwards, arrow 3.
The displays in the speedometer go out.
In addition, the system is automatically deacti‐
vated when:
▷The brakes are applied.▷Selector lever position N is engaged or
transmission position D is disengaged.▷When DTC is activated or DSC is deacti‐
vated.▷When DSC or ABS is intervening.
Cruise control is not deactivated by depressing
the accelerator pedal. Once the accelerator
pedal is released, the stored speed is achieved
again and maintained.
Warning lamp
The warning lamp comes on when
cruise control has been deactivated as
a result of DSC intervention, for exam‐
ple. A message appears on the Control Display.
Resuming a speed stored beforehand
Press the button, arrow 4. The last stored speed
is resumed and maintained.
In the following cases, the stored speed value is
deleted and cannot be called up again:▷When driving stability control systems inter‐
vene.▷When selector lever position N is engaged
or transmission position D is disengaged.▷When the ignition is switched off.

Do not remove the heat shields installed and
never apply undercoating to them. Make sure
that flammable materials, e. g. hay, leaves, grass,
etc. do not come in contact with the hot exhaust
system during driving, while in idle position
mode, or when parked. Such contact could lead
to a fire, and with it the risk of serious personal
injury as well as property damage.
Do not touch hot exhaust pipes; otherwise, there
is the danger of getting burned.◀
Mobile communication devices in the
vehicle
Mobile communication devices in the ve‐
hicle
It is not recommended to use mobile phones,
such as mobile phones without a direct connec‐
tion to an external aerial in the vehicle's passen‐
ger compartment. Otherwise, the vehicle elec‐
tronics and mobile communication devices can
interfere with each other. In addition, there is no
assurance that the radiation generated during
transmission will be discharged from the vehicle
interior.◀
Hydroplaning
On wet or slushy roads, a wedge of water can
form between the tires and road surface.
This phenomenon is referred to as hydroplan‐
ing. It is characterized by a partial or complete
loss of contact between the tires and the road
surface, ultimately undermining your ability to
steer and brake the vehicle.
Hydroplaning
When driving on wet or slushy roads, re‐
duce your speed to prevent hydroplaning.◀
The risk of hydroplaning increases as the tire
tread depth decreases. Minimum tread depth,
refer to page 234.Driving through water
Drive though calm water only if it is not deeper
than 12 inches/30 cm and at this height, no
faster than walking speed, up to 6 mph/10 km/h.
Adhere to water depth and speed limita‐
tions
Do not exceed this water depth and walking
speed; otherwise, the vehicle's engine, the elec‐
trical systems and the transmission may be
damaged.◀
Braking safely
Your vehicle is equipped with ABS as a standard
feature.
Applying the brakes fully is the most effective
way of braking in situations when this is neces‐
sary.
The vehicle maintains steering responsiveness.
You can still avoid any obstacles with a minimum
of steering effort.
Pulsation of the brake pedal and sounds from
the hydraulic circuits indicate that ABS is in its
active mode.
Do not let your foot rest on the brake pedal
Do not drive with your foot resting on the
brake pedal. Even light but consistent pedal
pressure can lead to high temperatures, brake
wear and possibly even brake failure.◀
Objects in the area around the pedals No objects in the area around the pedals
Keep floor mats, carpets, and any other
objects out of the area of motion of the pedals;
otherwise, the function of the pedals could be
impeded while driving
Do not place additional floor mats over existing
mats or other objects.
Only use floor mats that have been approved for
the vehicle and can be properly fixed in place.Seite 127Things to remember when drivingDriving tips127

Tire damage
General information
Inspect your tires often for damage, foreign ob‐
jects lodged in the tread, and tread wear.
Notes
Driving over rough or damaged road surfaces, as
well as debris, curbs and other obstacles can
cause serious damage to wheels, tires and sus‐
pension parts. This is more likely to occur with
low-profile tires, which provide less cushioning
between the wheel and the road. Be careful to
avoid road hazards and reduce your speed, es‐
pecially if your vehicle is equipped with low-pro‐
file tires.
Indications of tire damage or other vehicle de‐
fects:▷Unusual vibrations during driving.▷Unusual handling such as a strong tendency
to pull to the left or right.
Damage can be caused by driving over curbs,
road damage and similar situations.
In case of tire damage
If there are indications of tire damage, re‐
duce your speed immediately and have the
wheels and tires checked right away; otherwise,
there is the increased risk of an accident.
Drive carefully to the next service center or tire
shop.
If necessary, have the vehicle towed.
Otherwise, tire damage can present a life-
threatening hazard to vehicle occupants and
other road users.◀
Repair of tire damage
For safety reasons, the manufacturer of
your vehicle recommends that you do not have
damaged tires repaired; they should be re‐
placed. Otherwise, damage can occur as a re‐
sult.◀
Changing wheels and tires
Mounting Information on mounting tires
Have mounting and balancing performed
only by a service center or tire specialist.
If this work is not carried out properly, there is
the danger of subsequent damage and related
safety hazards.◀
Wheel and tire combination
Information on the right wheel and tire combi‐
nation and rim version for your vehicle can be
obtained from the service center.
Incorrect wheel and tire combinations impair the
function of a variety of systems such as ABS or
DSC.
To maintain good handling and vehicle re‐
sponse, use only tires with a single tread con‐
figuration from a single manufacturer.
Following tire damage, have the original wheel
and tire combination remounted on the vehicle
as soon as possible.
Approved wheels and tires
The manufacturer of your vehicle recom‐
mends that you use only wheels and tires that
have been approved for your particular vehicle
model.
For example, despite having the same official
size ratings, variations can lead to body contact
and with it, the risk of severe accidents.
The manufacturer of your vehicle cannot evalu‐
ate non-approved wheels and tires to determine
if they are suited for use, and therefore cannot
ensure the operating safety of the vehicle if they
are mounted.◀
Wheels with electronics for TPM Tire

When mounting new tires or changing from
summer to winter tires or vice versa, only use
wheels with TPM electronics; otherwise, theSeite 235Wheels and tiresMobility235

Maintain the battery in an upright position for
transport and storage. Secure the battery so
that it does not tip over during transport.
Fuses Replacing fuses
Never attempt to repair a blown fuse and
do not replace a defective fuse with a substitute
of another color or amperage rating; this could
lead to a circuit overload, ultimately resulting in
a fire in the vehicle.◀
Access to fuse box:
1.Open the glove compartment.2.Release the damper from the bottom holder
by applying pressure toward the front, ar‐
row 1.3.Unlock the glove compartment by pressing
on both tabs, arrows 2, and fold down.
