Dynamic Traction Control
DTC
The concept The DTC system is a version of the DSC in
which forward momentum is optimized.
The system ensures maximum forward mo‐
mentum on special road conditions, e.g., unp‐
lowed snowy roads, but driving stability is lim‐
ited.
It is therefore necessary to drive with appropri‐
ate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:▷When driving in sand, on snowy inclines, in
slush, or on unplowed, snow-covered road
surfaces▷When rocking a vehicle free or starting off
in deep snow, sand, or on loose ground▷When driving with snow chains.
Deactivating/activating DTC Dynamic
Traction Control
Activating the Dynamic Traction Control DTC
provides maximum traction on loose ground.
Driving stability is limited during acceleration
and when driving in bends.
Activating DTC
Press the button.
TRACTION is displayed in the instru‐
ment cluster and the indicator lamp for
DSC OFF lights up.

Performance Control
Performance Control enhances the agility of
your vehicle. To enhance performance during
sporty driving, the rear wheel on the inside of
the curve is braked while the resulting braking
effect is largely compensated by engine inter‐
vention.
xDrivexDrive is the all-wheel-drive system of your ve‐
hicle. The combined effects of xDrive and DSC
further optimize the traction and dynamic driv‐
ing characteristics. The 4-wheel drive system
xDrive variably distributes the drive forces to
the front and rear axle depending on the driv‐
ing situation and prevailing road conditions.
Hill Descent Control HDC
The concept HDC is a downhill driving assistant that auto‐
matically controls vehicle speed on steep
downhill gradients. Without requiring brake ap‐
plication, the vehicle moves at slightly more
than twice walking speed.
You can activate the Hill Descent Control at
speeds below approx. 22 mph/35 km/h. When
driving downhill at below approx.
22 mph/35 km/h, the vehicle reduces its speed
to approx. twice walking speed and keeps it
constant.
While you are actively braking, the system is
on standby. The system does not brake the
vehicle during this time.
Increasing or reducing speed
The speed can be changed in the range from
roughly twice walking speed to approx.
15 mph/25 km/h by pressing the accelerator or
brake pedal lightly.
A target speed within the same range can be
specified using the lever of the cruise control.1Increasing speed2Decreasing speedSeite 99Driving stability control systemsControls99

There is an increased danger of hydroplaning if
the tread depth is less than 0.12 in/3 mm.
Winter tires Do not drive with a tire tread depth of less than
0.16 in/4 mm.
Below a tread depth of 0.16 in/4 mm, tires are
less suitable for winter operation.
Minimum tread depth
Wear indicators are distributed around the
tire's circumference and have the legally re‐
quired minimum height of 0.063 in/1.6 mm.
They are marked on the side of the tire with
TWI, Tread Wear Indicator.
Tire damage
General information
Inspect your tires often for damage, foreign
objects 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
suspension parts. This is more likely to occur
with low-profile tires, which provide less cush‐
ioning between the wheel and the road. Be
careful to avoid road hazards and reduce your
speed, especially if your vehicle is equipped
with low-profile tires.
Indications of tire damage or other vehicle de‐
fects:▷Unusual vibrations during driving.▷Unusual handling such as a strong ten‐
dency 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; other‐
wise, 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.
