Tread depth
Check tread depth regularly. Should the
front tyres show greater wear than the rear
tyres, have both front wheels exchanged
with the rear wheels so that the tyres with
deeper tread are on the front axle.
For information on how to change a wheel
- see page 178.
Check the tyre pressures - see page 224.For safety reasons, tyres should be
replaced when their tread depth has worn
down to 2 to 3 mm. The legal permissible
minimum tread depth (1.6 mm) has been
reached when the tread has worn down as
far as one of the wear indicators.
A number of wear indicators are spaced at
equal intervals around the tyre, within the
tread. Their position is indicated by
markings on the tyre sidewall.General information
Note that the danger
of aquaplaning is
greater if the tyres are worn and if the tyre
pressures are not correct.
Tyres age, even if they are used only very
little or not at all. A spare wheel which has
not been used for six years should be used
only in emergencies: drive slowly when
using such tyres.
Never fit used tyres the previous history
and use of which you do not know.

Notes on temporary spare wheel
zUsing a temporary spare wheel may
change the driving behaviour of the
vehicle, particularly if using winter
tyres 3. Replace defective tyre as quickly
as possible, balanc e wheel and fit to
vehicle.
z Fit only one temporary spare wheel.
z Do not drive faster than 80 km/h
(50 mph).
z Take curves slowly.
z Do not use the temporary spare wheel
for a lengthy period.
z Replace temporary spare wheel with full
specification wheel without delay.
z When temporary spare wheel is fitted, do
not take the vehicle through an
automatic car wash with guide rails. The
temporary spare wheel may get caught
on the rails, causing damage to the tyre,
wheel and other vehicle parts.
z Tyre chains are not permitted on the
temporary spare wheel.
If tyre chains are necessary after a front
wheel puncture, fit the temporary spare
wheel to the rear and a rear wheel to the
front. Check tyre pressure and adjust if
necessary - see page 224.
z Follow the temporary spare wheel
instructions on pages 153, 181, 223. Notes on directional tyres
3
Tyres with a prescribed rotating direction
can only achieve their maximum
performance if they are fitted in the
prescribed rotating direction.
If a tyre or spare wheel is fitted that is
rotating in the wrong direction due to a
puncture, the following must be noted:
z The handling of the vehicle may be
different. Replace defective tyres as soon
as possible, have wheel balanced and
fitted to the vehicle.
z Do not drive faster than 80 km/h
(50 mph).
z Drive particularly carefully on wet and
snow-covered road surfaces.
z For more information on tyres with a
prescribed rotating direction -
see page 149.Wheel changing
In order to reduce the chance of possible
injuries, make the following preparations
and note the procedure:
zPark on a level, firm and non-slippery
surface.
z Switch on hazard warning lamps and
apply hand brake. Engage 1st gear or
reverse (automatic transmission 3 in P).
z Correctly set up warning triangle 3.
z Ensure all vehicle passengers are out of
the vehicle and clear of the vehicle and
other traffic.
z Take the spare wheel from under the
luggage compartment floor cover -
see page 177.
z Before raising the vehicle, turn front
wheels to straight-ahead position.

Self-help, vehicle care179
zRemove wheel trim 3.
z Slacken wheel nuts one turn only before
raising the vehicle, but do not totally
unscrew or remove the nuts until the
wheel is off the ground.
z Never change more th an one wheel at a
time.
z Block wheel diagonally opposite the
wheel to be changed, by placing wedge
blocks or equivalent in front and behind
the wheel.
z Do not jack-up the vehicle when traffic is
too close.
z Use jack only when changing wheels.
z Never exceed jack maximum working
load (900 kg).
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.
Using a thicker board could lead to
damage of the jack and the vehicle. z
Do not raise the vehicle more than is
necessary to change a wheel.
z No people or animals may be in the
vehicle when it is jacked-up.
z Never start or run the engine or crawl
under a jacked-up vehicle.
z Before screwing on the wheel nuts when
changing a wheel, ap ply a light coating
of grease to the cone of each wheel nut.
z Fully tighten the wheel nuts after
lowering the vehicle all the way, ensuring
nuts have been tightened to the correct
torque (see page 223).
z If conditions are not satisfactory to
change a wheel safely, consult a
workshop. 1. Prise off the wheel trim 3
.
2. Slacken the wheel nuts by one turn each using the wrench, putting the
wrench on as far as possible.

Electrical system
Fuses
There are two fuse boxes in the vehicle:
the instrument panel fu se box is located on
the left-hand side of the front passenger’s
footwell, the engine compartment fuse box
is located next to the coolant reservoir.
It is advisable to carry a full set of fuses.
Spare fuses are kept in the engine
compartment fuse box.
7. Change the wheel.
Notes on spare wheel - see page 178.
8. Screw on wheel nuts and tighten slightly by hand until wheel is held
against the hub.
9. Rotate wrench anti-clockwise and lower vehicle to the ground.
10. Tighten wheel nuts in a cross wise sequence, putting the wrench on as far
as possible.
11. Stow replaced wheel in luggage compartment.
12. Stow the jacking equipment and warning triangle 3 - see pages 176,
177.
13. Check the tyre pressure of the newly fitted wheel - see page 224. Adjust as
necessary.
14. Have the new wheel balanced on the vehicle and have the tightening torque
of the wheel nuts checked as soon as
possible, and if necessary, corrected.
Tightening torque - see page 223.
15. Replace defective tyre on the wheel that was removed.
16. Replace temporary spare wheel with a full specification wheel without delay.
9 Warning
Electronic ignition systems generate very
high voltages. Do not touch the ignition
system; high voltage can be fatal.

The paintwork of your vehicle is exposed to
environmental influences, e.g. continuous
changes in weather conditions, industrial
waste gases and dust or thawing salts, so
wash and wax your vehicle regularly. When
using automatic car washes, select a
program which includes waxing.
Bird droppings, dead insects, resin, pollen
and the like should be cleaned off
immediately, as they contain aggressive
constituents which can cause paint
damage.
If using a car wash, comply with the
pertinent instructions of the car wash
manufacturer. The windscreen wipers and
tailgate wipers must be switched off –
see pages 92, 93. Remove detachable rod
antenna by unscrewing it.
Do not use high-pressure jet cleaners.
If you wash your vehicle by hand, make
sure that the insides of the wings are also
thoroughly rinsed out. Do not use
household dishwashing liquid, to avoid
removing wax from the paintwork.
Clean edges and folds on opened doors
and flaps as well as the areas they cover.
Thoroughly rinse off and leather-off the
vehicle. Rinse leather frequently. Use
separate leathers for paint and window
surfaces; remnants of wax on the windows
will impair vision.
Also wash aluminium trim parts, avoiding
the use of abrasive materials such as
automotive or chrome polish, steam or
caustic soap. Washing with water is
normally sufficient.
Observe national regulations.
