2.Release the foot brake and drive away
without delay.
Depending on the vehicle load, the vehicle may
roll back slightly.
Driving off without delay
After releasing the foot brake, start driv‐
ing without delay, since the drive-off assistant
will not hold the vehicle in place for more than
approx. 2 seconds and the vehicle will begin
rolling back.◀
Self-leveling suspension The concept The self-leveling suspension on the rear axle
assures a continuous ground clearance.
To do so, the height of the vehicle is measured
by sensors at both rear wheels.
If the actual height deviates from the defined
height, such as due to cargo in the vehicle, this
difference is compensated very quickly. In ad‐
dition, spring motions resulting from cornering
or irregularities in the road surface are reduced
to a minimum.
The system works automatically.
Malfunctions Malfunctions are displayed via Check Control,
refer to page 76.
Active steering The concept
The active steering actively varies the steering
angle of the front wheels in relation to the
steering wheel movements. In addition, it also
varies the steering force required for steering
depending on the vehicle's speed.
When you are driving in the low speed range,
for instance in a town or when parking, the
steering angle increases, i.e., steering be‐
comes very direct. In the higher speed range,
on the other hand, the steering angle is re‐
duced more and more. This improves the han‐
dling of your vehicle over the entire speed
range.
In critical situations, the system can make tar‐
geted corrections to the steering angle pro‐
vided by the driver and thus stabilize the vehi‐
cle before the driver intervenes.
Malfunction The warning lamp lights up yellow
and a message is shown on the Con‐
trol Display. The active steering is de‐
fective or has been temporarily deac‐
tivated. At low speeds, greater steering wheel
movements are required, whereas at higher
speeds, the vehicle reacts more sensitively to
steering wheel movements. The stability-pro‐
moting intervention can also be deactivated.
Proceed cautiously and drive defensively.
Deactivation
Active steering deactivates in order to carry
out an initialization. This deactivation is dis‐
played by means of a message. The initializa‐ tion can take several minutes.
If the message does not disappear during the
current trip, have the system checked.
Defect In the event of a defect, a corresponding text
message is displayed. Have the system
checked.Seite 101Driving stability control systemsControls101

Driving in wet conditionsWhen roads are wet or there is heavy rain,
briefly exert gentle pressure on the brake pedal
every few miles.
Ensure that this action does not endanger
other road users.
The heat generated in this process helps dry
the brake discs and pads.
In this way braking efficiency will be available
when you need it.
Hills
Drive long or steep downhill gradients in the
gear in which the least braking is required.
Otherwise, the brake system may overheat, re‐
sulting in a reduction in the brake system effi‐
ciency.
You can increase the engine's braking effect
by shifting down in the manual mode of the au‐
tomatic transmission, refer to page 67.
Avoid load on the brakes
Avoid placing excessive load on the
brake system. Light but consistent brake pres‐
sure can lead to high temperatures, brake wear
and possibly even brake failure.◀
Do not drive in neutral
Do not drive in neutral or with the engine
stopped, as doing so disables engine braking.
In addition, steering and brake assist is un‐
available with the engine stopped.◀
Brake disc corrosion
Corrosion on the brake discs and contamina‐
tion on the brake pads are furthered by:▷Low mileage.▷Extended periods when the vehicle is not
used at all.▷Infrequent use of the brakes.
Corrosion occurs when the minimum pressure
that must be exerted by the pads during brake
applications to clean the discs is not reached.
Should corrosion form on the brake discs, the
brakes will tend to respond with a pulsating ef‐
fect that generally cannot be corrected.
Condensation under the parkedvehicle
When using the automatic climate control,
condensation water develops that exits under‐
neath the vehicle.
Therefore, traces of condensed water under
the vehicle are normal.
Driving on poor roads Your vehicle combines an all-wheel drive sys‐
tem with the advantages of a normal passen‐
ger car.
Do not drive on unpaved terrain
Do not drive on unpaved terrain, as oth‐
erwise the vehicle may be damaged.◀
For your own safety and the safety of passen‐
gers and the vehicle, adhere to the following
points:▷Familiarize yourself with the vehicle before
driving; never take risks.▷Adjust speeds according to road condi‐
tions. The steeper and rougher the road
surface is, the lower the speed should be.▷When driving on steep uphill and downhill
grades: the engine oil and coolant should
be filled nearly to the MAX mark.▷Use Hill Descent Control HDC, refer to
page 99, on steep downhill grades.▷Watch for stones, holes, and other obsta‐
cles and drive around these where possi‐
ble.▷On bumps and rough roads, avoid contact
between the vehicle body and the ground.
The maximum ground clearance is 8 in‐
ches/20 cm and may vary with the loaded
cargo.Seite 148Driving tipsThings to remember when driving148
