DTC Dynamic Traction
Control
The concept
The DTC system is a version of the DSC where
forward momentum is optimized.The system ensures maximum headway on
special road conditions or loose road surfaces,
e.g., unplowed snowy roads, but with some‐
what limited driving stability.
Activating the Dynamic Traction Control DTC
provides maximum traction. Driving stability is
limited during acceleration and when driving in
curves.
Therefore drive with appropriate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:▷When driving in slush or on uncleared,
snow-covered roads.▷When freeing vehicle from deep snow or
driving off from loose grounds.▷When driving with snow chains.

TRACTION is displayed in the instru‐
ment cluster and the indicator lamp for DSC

tor lamp go out.
Performance Control Performance Control enhances the agility of
the vehicle.
To increase maneuverability, with a corre‐
spondingly sporty driving style, wheels are
braked individually. The resulting braking
power is simultaneously largely compensated
by an engine intervention.

xDrivexDrive is the all-wheel-drive system of your ve‐
hicle. Concerted action by the xDrive and DSC
further optimize traction and driving dynamics.
The xDrive all-wheel-drive system variably dis‐
tributes the drive forces to the front and rear
axles as demanded by the driving situation and
road surface.

HDC Hill Descent Control
The concept HDC is a downhill driving assistant that auto‐
matically controls vehicle speed on steep
downhill gradients. Without applying the
brakes, the vehicle moves at slightly more than
walking speed.
Hill Descent Control can be activated at
speeds below approx. 22 mph/35 km/h. When
driving downhill, the vehicle reduces its speed
to approx. walking speed and then keeps its
speed constant.
As long as there is active braking, the system
is on standby. The system does not brake the
vehicle during this time.
Only use HDC in low gears or in selector lever
position D or R.
Increasing or decreasing vehicle
speed
Specify desired speed in the range from ap‐
prox. 4 mph/6 km/h to approx. 15 mph/25 km/h
using the rocker reel of the cruise control on
the steering wheel. Vehicle speed can be
changed by lightly accelerating.▷Press the rocker reel up to the point of re‐
sistance: the speed increases gradually.▷Press up the rocker reel past the point of
resistance: the speed increases while the
rocker reel is pressed.▷Press the rocker reel down to the point of
resistance: the speed decreases gradually.▷Press the rocker reel down past the point
of resistance: when driving forward, the
speed decreases to approx.
6 mph/10 km/h; when reversing, the speed
decreases to approx. 4 mph/6 km/h.

Cruise controlThe concept The system maintains a preset speed via the
buttons on the steering wheel. The system
brakes on downhill gradients if engine braking
is insufficient.
General information
Depending on the driving settings, the features
of the cruise control can change in certain
areas.
Hints Unfavorable conditions
Do not use the system if unfavorable
conditions make it impossible to drive at a con‐
stant speed, e.g.:▷On winding roads.▷In heavy traffic.▷On slippery roads, in fog, snow or rain, or
on a loose road surface.

Things to remember when drivingVehicle features and options
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems.
Breaking-in period
General information Moving parts need time to adjust to one an‐
other (break-in time).
The following instructions will help accomplish
a long vehicle life and good efficiency.
During break-in, do not use the Launch Con‐
trol, refer to page 78.
Engine, transmission, and axle drive Always obey the official speed limit.
Up to 1,200 miles/2,000 km
Do not exceed the maximum engine and road
speed:▷For gasoline engine 4,500 rpm and
100 mph/160 km/h.▷For diesel engine 3,500 rpm and
93 mph/150 km/h.
Avoid full load or kickdown under all circum‐
stances.
From 1,200 miles/2,000 km The engine and vehicle speed can gradually be
increased.
Tires
Tire traction is not optimal due to manufactur‐
ing circumstances when tires are brand-new;
they achieve their full traction potential after a
break-in time.
Drive conservatively for the first
200 miles/300 km.
Brake system
Brakes require an initial break-in period of ap‐
prox. 300 miles/500 km to achieve optimal per‐
formance between brake discs and brake
pads. Drive moderately during this break-in pe‐
riod.
Following part replacement The same break-in procedures should be ob‐
served if any of the components above-men‐
tioned have to be renewed in the course of the
vehicle's operating life.
Driving on poor roads
The vehicle connects four wheel drive to the
advantages of a normal truck
Do not drive on unpaved terrain
Do not drive on unpaved terrain; other‐
wise, the vehicle may be damaged.◀
For your own safety, for the safety of passen‐
gers and of the vehicle, heed the following
points:▷Become familiar with the vehicle before
starting a trip; do not take risks in driving.▷Adjust the speed to the road surface con‐
ditions. The steeper and more uneven the
road surface, the slower the speed should
be.▷When driving on steep uphill or downhill
grades: add engine oil and coolant up toSeite 172Driving tipsThings to remember when driving172

Coasting
The concept
The system helps to conserve fuel.
To do this, under certain conditions the engine
is automatically decoupled from the transmis‐
sion when selector lever position D is set. The
vehicle continues traveling with the engine
idling to reduce fuel consumption. Selector
lever position D remains engaged.
This driving condition is referred to as coast‐
ing.
As soon as you step on the brake or accelera‐
tor pedal, the engine is automatically coupled
again.
Hints
Coasting is a component of the ECO PRO, re‐
fer to page 180, driving mode.
Coasting is automatically activated when ECO
PRO mode is called via the Driving Dynamics
Control.
The function is available in a certain speed
range.
A proactively driving style helps the driver to
use the function as often as possible and sup‐
ports the fuel-conserving effect of coasting.
Safety mode
The function is not available under one of the
following conditions.▷DSC OFF or TRACTION activated.▷Driving in the dynamic limit range and on
steep uphill or downhill grades.▷Battery charge status temporarily too low
or vehicle electrical system drawing exces‐
sive current.▷Cruise control activated.
Functional requirements
In ECO PRO mode, this function is available in
a speed range from approximately 30 mph, ap‐
prox. 50 km/h to 100 mph, approx. 160 km/h, if
the following conditions are met:
▷Accelerator pedal and brake pedal are not
operated.▷The selector lever is in selector lever posi‐
tion D.▷Engine and transmission are at operating
temperature.
The driving status Coast can be influenced
with the shift paddles.
