226Vehicle careTemporary spare wheelCaution
The use of a spare wheel that issmaller 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
80 km/h. 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 at
the front and the full size tyre at the
rear.
Tyre chains 3 217.
Spare wheel with directional tyre
Fit directional tyres such that they roll in 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
and fit it instead of the spare
wheel.
● 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.
● Never expose the battery to naked flames or sparks.

Vehicle care227● A discharged vehicle battery canalready 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
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
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,
automatic transmission in P.
● Open the positive terminal protection caps of both 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 far away from the discharged
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.
2. After 5 minutes, start the other engine. Start attempts should be
made for no longer than
15 seconds at an interval of
1 minute.
3. Allow both engines to idle for approx. 3 minutes with the leads
connected.
