Temporary spare wheel
Caution
The use of a spare wheel that is smaller than the other wheels or in combination with winter tyres
could affect driveability. Have the defective tyre replaced as soon as
possible.
Only mount one temporary spare
wheel. Do not drive faster than
50 mph. Take curves slowly. Do not
use for a long period of time.
If your vehicle gets a flat tyre on the
rear while towing another vehicle,
mount the temporary spare wheel in
the front and the full tyre in the rear.
Tyre chains 3 263.
Spare wheel with directional tyre Fit directional tyres such that they rollin the direction of travel. The rolling
direction is indicated by a symbol
(e.g. an arrow) on the sidewall.
The following applies to tyres fitted
opposing the rolling direction:
■ Driveability may be affected. Have the defective tyre renewed or
repaired as soon as possible.
■ Drive particularly carefully on wet and snow-covered road surfaces.Jump starting
Do not start with 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.

276Vehicle care
■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 vehicle
battery before connecting jump
leads.
■ Wear eye protection and protective
clothing when handling a vehicle
battery.
■ Use a booster vehicle 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.
■ 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
vehicle battery.
2. Connect the other end of the red lead to the positive terminal of the
discharged vehicle battery.
3. Connect the black lead to the negative terminal of the booster
vehicle 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 far away from the discharged
vehicle battery as possible,
however at least 60 cm.
Route the leads so that they cannot
catch on rotating parts in the engine
compartment.
To start the engine: 1. Start the engine of the vehicle providing the jump.
