Switching off

ESP®
Plus
can be deactivated by pressing
button v 3 .
Switching off is indicated by the control
indicator v lighting up in the
instrument. Also appears on the service
display ESPoff391.
Pressing the v button again or turning on
the ignition switches the ESP®
Plus
on again. Cruise control
3
Cruise control can store and maintain
speeds between 30 and 200 km/h.
Deviation from the stored speed may occur
when driving up or downhill.
For safety reasons the cruise control
system cannot be activated until the foot
brake has been operated, otherwise the
control indicator flashes m.
Cruise control is operated with switch m, g,
and button 0 on the turn signal stalk.
Do not use the cruise control if it is not
advisable to maintain a constant speed
(e.g. in situations presenting a danger to
yourself and other road users, in heavy
traffic or on winding, slippery or greasy
roads). With automatic transmission
3, engage
cruise control only in D, or with manual
transmission automated 3 in automatic
mode only.
9
Warning
If the vehicle has run-flat tyres 3 the
ESP®
Plus
must not be deactivated with
depressurised tyres.
9
Warning
When the cruise control is active, reac-
tion times may be increased due to the
different position of the feet.

Hydraulic brake system The foot brake comprises two independent
brake circuits.
If a brake circuit fails, the vehicle can still be
braked using the other brake circuit.
However, the brake pedal must be
depressed a considerable way before any
braking effect occurs, and much more
force is required. The braking distance is
longer. Contact a workshop for assistance
before continuing to drive. To ensure that full
pedal travel can be
utilised, especially in case of a fault in one
of the brake circuits, there must be no mats
in the vicinity of the pedals 3150.
When the engine is not running, the
support of the brake servo unit disappears
once the brake pedal has been depressed
once or twice. Braking effect is not
reduced, but braking requires significantly
greater force. This is especially important
to bear in mind when towing.
The brake fluid level should be checked
regularly. If the brake fluid level is too low
and the hand brake is not applied, control
indicator R on the instrument panel
illuminates 389.
Picture no: 18257s.tif
Brake system control indicator R
The control indicator lights up when the
ignition is switched on when the hand
brake is applied or when the brake or
clutch fluid level is too low. Brake fluid
level 3246.
For vehicles with manual transmission
automated 3, the control indicator flashes
for a few seconds when the ignition is
turned off when the hand brake is not
applied.
9
Warning
If the control indicator illuminates when
the hand brake is released, stop driving
immediately. Contact a workshop for
assistance.

Hand brake Always apply hand brake firmly without
pressing the release button, and apply as
firmly as possible on steep slopes.
To release the hand brake pull lever up
slightly, press release button, and lower
lever all the way down.
To reduce the operating forces of the hand
brake, depress the foot brake at the same
time.
Brake assist
3
If the brake pedal is operated quickly with
a powerful push, the vehicle is
automatically braked at full braking power
in order to achieve the shortest possible
braking distance when full-on braking
occurs (brake assist).
Maintain steady pressure on the brake
pedal for as long as full-on braking is to
continue. When the brake pedal is
released, the maximum brake force
amplification is taken away.
Hill Start Assist
3 (HSA)
The system helps pull away on inclines.
After releasing the footbrake, if the hand
brake is not applied the brakes are only
released after 2 seconds. As soon as the
acceleration is sufficient to prevent rolling
back, the brake is released.

Driving characteristics, towing tips
Before attaching the trailer/caravan,
lubricate the ball of the trailer/caravan
towing device. However, do not lubricate
the ball if a stabiliser, which acts on the
coupling ball, is being used to damp
hunting.
Check caravan/traile r lighting before
starting to drive. The fog tail lamps on the
vehicle are deactivated when towing a
caravan or trailer.
Trailers with LED turn signals must have a
provision enables lamp monitoring for
commercial bulbs.
Ultrasonic parking sensors 3 are
deactivated in towing mode.
Handling is greatly influenced by the
loading of the trailer/caravan. Loads
should therefore be secured so that they
cannot slip and be placed in the centre of
the trailer/caravan if possible, i.e. above
the axle.
For trailers with low directional control and
for caravans with a permissible gross
vehicle weight of more than 1000 kg, a
speed of 80 km/h must not be exceeded;
use of a roll damper in accordance with the
friction principle is urgently recommended. If the trailer/caravan starts to sway, drive
more slowly, do not attempt to correct the
steering and brake sharply if necessary.
If it is necessary to apply the brakes fully,
depress the brake pedal as hard as
possible.
Remember that the braking distance for
vehicles towing caravans/trailers with and
without brake is always greater than that
for vehicles not towing a caravan/trailer.
When driving downhill, drive in the same
gear as if driving uphill and drive at a
similar speed.
Adjust tyre pressure to the value specified
for full load
3264. Starting on inclines
For vehicles with manual transmission, the
most favourable engine speed when
starting off on an incline is between
2500 and 3000 rpm for petrol engines and
between 2000 and 2200 rpm for diesel
engines. Hold engine speed constant,
engage clutch gradually (let slip), release
hand brake and open throttle. If possible,
the engine speed should not drop during
this procedure.
In vehicles with automatic transmission
3
and manual transmission automated 3 it is
sufficient to give full throttle in D or
(in automatic mode) 3.
Before starting off under extreme
operating conditions, switch off
unnecessary consumers.

200 Self-help, vehicle careChanging wheels There may be a tyre repair kit instead of a
spare wheel 3204.
Make the following preparations and
observe the following information:
z Park the vehicle on a level, firm and non-
skid surface. The front wheels must be in
the straight-ahead position.
z Switch on hazard warning lights, apply
hand brake, automa tic transmission 3 -
selector lever in P , manual transmission
or manual automatic transmission 3 -
engage 1st or reverse gear.
z Erect warning triangle 3 as specified.
Warning triangle 3196.
z Remove spare wheel from luggage
compartment 3196. z
Never change more than one wheel at
once.
z Use the jack 3 only to change wheels.
z If the ground on which the vehicle is
standing is soft, a solid board (max. 1 cm
thick) should be placed under the jack 3.
z Block the wheel diagonally opposite the
wheel to be changed by placing wedge
blocks or equivalent in front and behind
the wheel. z
No people or animals may be in the
vehicle when it is jacked up.
z Never crawl under a jacked-up vehicle.
z Do not start the vehicle when it is raised
on the jack.
z Before screwing in the wheel bolts, clean
them and lightly coat the taper of each
wheel bolt with comm ercially available
grease.
