Do not remove foreign bodies from
the tyres.
Tyre damage exceeding 4 mm or that
is at tyre's side wall cannot be
repaired with the tyre repair kit.9 Warning
Do not drive faster than 80 km/h.
Do not use for a lengthy period.
Steering and handling may be
affected.
If you have a flat tyre:
Apply the parking brake and engage
first gear, reverse gear or P.
The tyre repair kit is in a compartment
under the floor cover in the load
compartment.
1. Take the tyre repair kit from the compartment.
2. Remove the compressor.3. Remove the electrical connection cable and air hose from the
stowage compartments on the
underside of the compressor.

248Vehicle care
Make the following preparations and
observe the following information:
■ Park the vehicle on a level, firm and
non-skid surface. The front wheels
must be in the straight-ahead
position.
■ Apply the parking brake and engage first gear, reverse gear or
P .
■ Remove the spare wheel 3 250.
■ Never change more than one wheel
at once.
■ Use the jack only to change wheels
in case of puncture, not for
seasonal winter or summer tyre
change.
■ If the ground on which the vehicle is standing is soft, a solid board
(max. 1 cm thick) should be placed
under the jack.
■ No people or animals may be in the
vehicle when it is jacked-up.
■ Never crawl under a jacked-up vehicle.■ Do not start the vehicle when it is
raised on the jack.
■ Clean wheel nuts and thread with a
clean cloth before mounting the
wheel.9 Warning
Do not grease wheel bolt, wheel
nut and wheel nut cone.
1. Disengage wheel nut caps with a screwdriver and remove. Pull off
the wheel cover with the hook.
Vehicle tools 3 239.
Alloy wheels: Disengage wheel
nut caps with a screwdriver and
remove. To protect the wheel,
place a soft cloth between the
screwdriver and the alloy wheel.
2. Fold out the wheel wrench and install ensuring that it locates
securely and loosen each wheel
nut by half a turn.

Vehicle care253
■Never expose the vehicle battery to
naked flames or sparks.
■ A discharged vehicle battery can already freeze at a temperature of
0 °C. Defrost the frozen battery
before connecting jump leads.
■ Wear eye protection and protective
clothing when handling a battery.
■ Use a booster battery with the same voltage (12 Volts). Its
capacity (Ah) must not be much less than that of the discharged
vehicle battery.
■ Use jump leads with insulated terminals and a cross section of at
least 16 mm 2
(25 mm 2
for diesel
engines).
■ Do not disconnect the discharged vehicle battery from the vehicle.
■ Switch off all unnecessary electrical
consumers.
■ Do not lean over the vehicle battery
during jump starting.
■ Do not allow the terminals of one lead to touch those of the other
lead.■ The vehicles must not come into contact with each other during the
jump starting process.
■ Apply the parking brake, transmission in neutral, automatic
transmission in P.
■ If there is a cover over the vehicle
battery, remove it to charge or jumpstart the vehicle battery. Lift up the
cover at the rear and unlatch it at
the front.
■ 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 booster
battery.
4. Connect the other end of the black
lead to a vehicle grounding point,
such as the engine block or an
engine mounting bolt. Connect as

OPC: insert screwdriver in the slot at
the upper bend of the cap. Release
the cap by carefully moving the
screwdriver downwards. To prevent
damage it is recommended to place a cloth between the screwdriver and
the frame.
The towing eye is stowed with the
vehicle tools 3 239.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.
Transmission in neutral.
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 manual transmission
and All-wheel drive: If the vehicle is
towed with all four wheels on the
ground then there are no technical
limitations for speed and distance. If
only one axle has been raised, the
maximum speed is 50 km/h. There is
no distance limitation.
Vehicles with automatic transmission and Front-wheel drive: 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.

Service and maintenance263
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 266.
Additional engine oil additives
The use of additional engine oil
additives could cause damage and
invalidate the warranty.
Engine oil viscosity grades
The SAE viscosity grade gives
information of the thickness of the oil.
Multigrade oil is indicated by two
figures, e.g. SAE 5W-30. The first
figure, followed by a W, indicates the
low temperature viscosity and the
second figure the high temperature viscosity.
Select the appropriate viscosity grade depending on the minimum ambient
temperature 3 266.
All of the recommended viscosity
grades are suitable for high ambient
temperatures.Coolant and antifreeze
Use only silicate-free long life coolant (LLC) antifreeze.
The system is factory filled with
coolant designed for excellent
corrosion protection and frost
protection down to approx. -28 °C.
This concentration should be
maintained all year round. The use of
additional coolant additives that
intend to give additional corrosion
protection or seal against minor leaks can cause function problems. Liability
for consequences resulting from the
use of additional coolant additives will be rejected.
Brake and clutch fluid Only use high-performance brake
fluid approved for the vehicle, consult a workshop.
Over time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should
therefore be replaced at the specified
interval.Brake fluid should be stored in a
sealed container to avoid water
absorption.
Ensure brake fluid does not become
contaminated.
