Deflation detection system (DDS)3
The deflation detection system monitors
the revolutions of all four vehicles from a
speed of approximately 30 km/h. If there is
a loss of pressure in one of the tyres, its
diameter is reduced, and therefore also the
wheel rotation speed. Warning lamp w
lights red.
Stop immediately and check tyre pressure.
Fit the spare wheel if necessary 3 196,
3 200. Control indicator
w
If control indicator w lights up red while
driving, there is a loss of pressure. Stop
immediately and check tyre pressures. A
maximum speed of 80 km/h is permitted
for tyres run flat 3 3 171.
Control indicator illumination w in yellow
indicates a fault in the system. Have cause
of fault remedied by a workshop. The
system’s integrated se lf diagnostics allow
faults to be quickly remedied.
The control indicator flashes three times
when the system is initialising.
Tyre pressure 3169, 3264.
Picture no: 18245s.tif
System initialisationAfter correcting the tyre pressure or
changing a tyre/wheel, the system must be
initialised: turn the ignition on, press the
DDS button for approx. 4 seconds. Control
indicator w flashes three times. The system
is operational after driving a certain
distance.
Only initialise the system if all tyres have
the prescribed pressure.
9
Warning
The deflation detection system does not
replace manual checks with a suitable
gauge.
Check tyre pressures at least every
14 days and prior to any long journey;
the tyres should be checked when cold.
Don’t forget to check the spare 3.

Driving and operation

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.

First place the front (1) tail lamp, then the
rear (2) tail lamp in the recesses and push
down as far as possible. Push cables all the

system into the bumper until it engages.
Release lever must return to original
position.

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.

Minor damage to the tyre tread or side wall
can be repaired using the tyre repair kit
(does not apply to run-flat tyres).
Do not remove the foreign body from the
tyre.
T y r e d a m a g e e x c e e d i n g 4 m m o r t ha t i s o n
the rim cannot be repaired with the tyre
repair kit.
Important 3207.
In the event of a flat tyre:
z Switch on hazard warning lights, apply
handbrake, engage 1st or reverse gear,
in the case of automatic transmission 3
move selector lever to position P.
z Erect warning triangle 3 as specified.
Warning triangle 3196.
Picture no: 18317s.tif
The tyre repair kit is located in the
compartment to the right in the luggage
compartment.
To open the compartment, disengage the
cover and open it.

Warning
Do not drive faster than 80 km/h.
Do not use the temporary spare wheel
for a lengthy period.
Steering and handling may be affected.

Self-help, vehicle care
Polishing and waxing
Wax the vehicle regularly (by the time the
water no longer beads at the latest).
Otherwise, the paintwork will dry out.
Polishing is necessary only if the paint has
become dull or if solid deposits have
become attached to it.
Paintwork polish with silicone forms a
protective film, making waxing
unnecessary.
Plastic body parts should not be treated
with wax and polish.
Wheels and tyres
Do not use high-pressure jet cleaners.
Clean wheels with a pH-neutral wheel
cleaner.
Wheels are painted and can be treated
with the same agents as the body.
Paintwork damage
Rectify minor paintwork damage with a
touch-up pen before rust forms. Have more
extensive damage or rust areas repaired
by a workshop. Exterior lights
Headlamp and other lamp covers are
made of plastic. Do not use any caustic
agents, do not use an ice scraper, and do
not clean them when dry.
Plastic and rubber parts
Plastic and rubber parts can be cleaned
with the same cleaner as used to clean the
body. Use interior cleaner if necessary. Do
not use any other agent. Avoid solvents
and petrol in particular. Do not use high-
pressure jet cleaners.
Interior and upholstery
Only clean the vehicle interior, including
the instrument panel fa
scia and panelling,
with a dry cloth or interior cleaner.
The instrument pane l should only be
cleaned using a soft damp cloth.
Clean fabric upholstery with a vacuum
cleaner and brush. Remove stains with an
upholstery cleaner.
Clean seat belts with lukewarm water or
interior cleaner.
Caution
Close Velcro fasteners as open Velcro
fasteners on clothing could damage
seat upholstery.
