Driving and operating143Cruise control is deactivated, but not
switched off. Last stored speed
remains in memory for later speed
resume.
Cruise control is deactivated
automatically when:
● The brake pedal is depressed.
● Vehicle speed is below 40 km/h.
● The Traction Control system or Electronic Stability Control is
operating.
● The manual transmission is in N,
first or second gear.
● The automatic transmission is in position M and first gear.
Resume stored speed
Move thumb wheel to RES/+ at a
speed above 40 km/h. The stored
speed will be obtained.
Switching off the system
Press m: the cruise control mode is
deselected and the cruise control
indication extinguishes in the Driver
Information Centre.Pressing ß to activate the speed
limiter deactivates cruise control.
Switching off the ignition cancels any
programmed speed value.
Fault
In the event of a cruise control fault, the speed is cleared resulting in
flashing of the dashes.
The speed limit recognition may not
operate correctly if traffic signs do not
comply with the Vienna Convention
on Road Signs and Signals.
Speed limiter
The speed limiter prevents the
vehicle from exceeding a preset
maximum speed.
The maximum speed can be set at
speeds above 30 km/h.
The driver can accelerate the vehicle
up to the preset speed. Deviations
from the limited speed may occur
when driving downhill.
The preset speed can be exceeded
temporarily by pressing the
accelerator pedal firmly.The status and preset speed limit is
displayed in the Driver Information Centre.
Switching on the system
Press ß, symbol ß and a message
are displayed in the Driver
Information Centre. The system is still not active.

170Driving and operatingTrailer towingTrailer loadsThe permissible trailer loads are
vehicle and engine-dependent
maximum values which must not be
exceeded. The actual trailer load is
the difference between the actual
gross weight of the trailer and the
actual coupling socket load with the
trailer coupled.
The permissible trailer loads are
specified in the vehicle documents. In
general, they are valid for inclines up
to 12%.
The permissible trailer load applies
up to the specified incline and at sea
level. Since engine power decreases
as altitude increases due to the air
becoming thinner, therefore reducing
climbing ability, the permissible gross train weight also decreases by 10%
for every 1000 m of altitude. The
gross train weight does not have to be
reduced when driving on roads with
slight inclines (less than 8%, e.g.
motorways).The permissible gross train weight must not be exceeded. This weight is
specified on the identification plate
3 221.
Vertical coupling load
The vertical coupling load is the load
exerted by the trailer on the coupling
ball. It can be varied by changing the
weight distribution when loading the
trailer.
The maximum permissible vertical
coupling load of 65 kg is specified on the towing equipment identification
plate and in the vehicle documents.
For vehicles with engine DV5RC and
automatic transmission, the
maximum permissible vertical
coupling load is 55 kg. Always aim for the maximum load, especially in the
case of heavy trailers. The vertical
coupling load should never fall below
25 kg.Rear axle load
When the trailer is coupled and the
towing vehicle fully loaded, the
permissible rear axle load (see
identification plate or vehicle
documents) may be exceeded by
60 kg , the gross vehicle weight rating
must not be exceeded. If the
permissible rear axle load is
exceeded, a maximum speed of
100 km/h applies.
Towing equipmentCaution
When operating without a trailer,
remove the coupling ball bar.
Stowage of coupling ball bar
The bag with the coupling ball bar is
stowed on the rear floor cover in the
load compartment.

208Vehicle care● The vehicles must not come intocontact with each other during
the jump starting process.
● Apply the parking brake, transmission in neutral,
automatic transmission in P.
Open the positive terminal protection
caps of both vehicle batteries.
Lead connection order: 1. Connect the red lead to the positive terminal of the booster
battery.
2. Connect the other end of the red lead to the positive terminal of the
discharged battery.
3. Connect the black lead to the negative terminal of the boosterbattery.
4. Connect the other end of the black
lead to a vehicle grounding point
of your vehicle in the engine
compartment.
Route the leads so that they cannot
catch on rotating parts in the engine
compartment.
To start the engine: 1. Start the engine of the vehicle providing the jump.
2. After 5 minutes, start the other engine. Start attempts should be
made for no longer than
15 seconds at an interval of
1 minute.
3. Allow both engines to idle for approx. 3 minutes with the leads
connected.
4. Switch on electrical consumers (e.g. headlights, heated rear
window) of the vehicle receiving
the jump start.
5. Reverse above sequence exactly when removing leads.Towing
Towing the vehicle
Wrap a cloth around the tip of a flat
screwdriver to prevent paint damage.
Insert a screwdriver in the slot at the
bottom of the cap. Release the cap by carefully moving the screwdriver
downwards.
The towing eye is stowed with the vehicle tools 3 194.
Page 211 of 253

Vehicle care209
Screw in the towing eye as far as it will
go until it stops in a horizontal
position.
Attach a tow rope – or better still a tow
rod – to the towing eye.
The towing eye must only be used for towing and not for recovering the
vehicle.
Switch on ignition to release steering
wheel lock and to permit operation of
brake lights, horn and windscreen
wiper.
Caution
Deactivate the driver assistance
systems like active emergency
braking 3 147, otherwise the
vehicle may automatically brake during towing.
Switch the selector lever to neutral.
Release the parking brake.
Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
When the engine is not running,
considerably more force is needed to
brake and steer.
To prevent the entry of exhaust gases from the towing vehicle, switch on the
air recirculation and close the
windows.
Vehicles with automatic transmission: The vehicle must be towed facing
forwards, not faster than 80 km/h nor further than 100 km. In all other cases
and when the transmission is
defective, the front axle must be
raised off the ground.
Seek the assistance of a workshop.
After towing, unscrew the towing eye.
Insert cap with the outer flange into
the recess and fix cap by pushing.
Towing another vehicle
Wrap a cloth around the tip of a flat
screwdriver to prevent paint damage.
Insert a screwdriver in the slot at the
bottom of the cap. Release the cap by carefully moving the screwdriver
downwards.
