224Vehicle careJump startingDo not start with a quick charger.
A vehicle with a discharged vehicle
battery can be started using jump
leads and the vehicle battery of
another vehicle.9 Warning
Be extremely careful when starting
with jump leads. Any deviation
from the following instructions can
lead to injuries or damage caused
by battery explosion or damage to the electrical systems of both
vehicles.
9 Warning
Avoid contact of the battery with
eyes, skin, fabrics and painted
surfaces. The fluid contains
sulphuric acid which can cause
injuries and damage in the event
of direct contact.
■ Never expose the 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 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, automatictransmission in P.
■ Open the positive terminal protection caps of both vehicle
batteries.

Service and maintenance233
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 236.
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 3 236.
All of the recommended viscosity
grades are suitable for high ambient
temperatures.Coolant and antifreeze
Use only silicate-free long life coolant (LLC) antifreeze. Consult a
workshop.
The system is factory filled with
coolant designed for excellent
corrosion protection and frost
protection down to approx. -28 °C. In
northern countries with very low
temperatures the factory filled coolant
provides frost protection down to
approx. -37 °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 Over time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should
therefore be replaced at the specified
interval.
