license plates, vehicle lighting, turn
signals, brake lamps
and wiper blades for
dirt and damage
R tires and wheels for firm seating, correct
tire pressure and general condition
R trailer tow hitch for play and security

Steering G
Warning
Do not switch off the engine while the vehicle
is in motion.
There is no
power assistance for the steering
or the service brake when the engine is not
running.
Steering and braking require significantly
more effort and you could lose control of the
vehicle and cause an accident as a result.
! Do not hold the steering wheel at full
steering angle for a long time, e.g. when
turning or maneuvering.
The hydraulic pump could be damaged if
the hydraulic fluid temperature increases.
Overrun cut-off If you take your foot off the accelerator pedal,
the diesel fuel supply is cut off in overrun
mode when the
engine speed is out of the idle
speed control range. 110

ADR (working speed governor)
When activated, the working speed governor
(ADR) automatically increases the engine
speed to a preset or adjustable speed
(Y page 117).
i After a cold start, the idling speed of the
engine is increased automatically. If the
preset working speed is lower than the
increased idling speed, the working speed
is only reached once the engine has
completed the warm-up phase.
It is only possible to activate ADR with the
vehicle stationary and the parking brake
applied.
The selector lever must be in position P.
Activating/deactivating ADR X
To activate: press upper
section 0046 of the
0093 switch while the engine is running.

ADR is automatically deactivated when:
R you release the parking brake.
R the brake pedal is depressed.
R the vehicle moves.
R the control unit detects a malfunction.

i On vehicles with cruise control, you can
use the cruise control lever to increase or
decrease the engine
speed in the same way
as for the road speed. Set the speed using
the cruise control lever (Y page 119).
i After a cold start, the idling speed of the
engine is increased automatically.
You can only reduce the working speed to
the level of the current idling speed. Driving systems
Overview
The
following pages
describe driving systems
that may be a component in your vehicle:
R Cruise control ( Y page 118) which you can
use to control the speed of your vehicle
R PARKTRONIC ( Y page 119) and the rear

Controls Z
Cruise control
General notes Cruise control maintains the speed of the
vehicle for you.
Use cruise control if road and traffic
conditions make it appropriate to maintain a
steady speed
for
a prolonged period. You can
set any speed from 20 mph upwards in
increments of 1 mph.
i If you have set km/h as the unit for the
digital speedometer , you can set any speed
from 30 km/h upwards in increments of
1 km/h. G
Warning
Cruise control is unable to take account of
road and traffic conditions.
Always pay attention
to the traffic conditions,
even when cruise control is activated.
Cruise control is only an aid designed to assist
driving. You are always responsible for the
vehicle's speed and for braking in good time.
If there is a change of drivers, make sure that
you inform the new driver about the set cruise
speed. Otherwise, sudden acceleration or
braking could endanger you or others. G
Warning
Do not use cruise control:
R in road and traffic conditions which do not
allow you to
maintain a constant speed (e.g.
heavy traffic or winding roads). You could
otherwise cause an accident.
R on slippery roads. Braking or accelerating
could cause the drive wheels to lose
traction and the vehicle could then skid.
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
i Cruise control may not be able to
maintain the stored speed on uphill or
downhill gradients. The stored speed is
resumed if the gradient evens out and the
vehicle's speed does not fall below 20 mph
(30 km/h). Cruise control lever The cruise control lever is the uppermost
lever on the left of the steering column.

R you depress the brake pedal.
R you apply the parking brake and the 0066
indicator lamp in the instrument cluster
lights up.
i Other drive and brake systems not
described in this Operator's Manual, such
as a
