Vehicle tools, tyre repair kit and spare wheel
Vehicle Tools
The vehicle tools are located under the floor panel in the
luggage compartment. – Lift the cover of the luggage compartment, by pulling it up with
a finger in the fitting.
– Take the vehicle tools out of the vehicle.
The vehicle tool kit includes:
● Jack*
● Hook for removing wheel covers* or hub caps*
● Box spanner for wheel bolts*
● Towline anchorage
● Adapter for the anti-theft wheel bolts*
Some of the items listed are only provided in certain model versions, or are
optional extras.
WARNING
● The factory-supplied jack* is only designed for changing wheels on
this model. On no account attempt to use it for lifting heavier vehicles or
other loads. Risk of injury.
● Use the jack* only on firm, level ground.
WARNING (Continued)
● Never start the engine when the vehicle is on the jack. Risk of acci-
dent.
● If work is to be carried out underneath the vehicle, this must be se-
cured by suitable stands. Otherwise, there is a risk of injury.
Compact temporary spare wheel (emergency wheel)
The compact spare wheel (temporary spare wheel for vehi-
cles without the anti-puncture kit) should only be used when
strictly necessary.

If and when
Wheel change Preparation work
What you must do before changing a wheel.
– If you have a flat tyre or puncture, park the vehicle as far away
from the flow of traffic as possible. Choose a location that is as
level as possible.
– All vehicle occupants should leave the vehicle. They should
wait in a safe area (for instance behind the roadside crash barri-
er).
– Switch off the engine. Switch on the hazard warning lights.
– Apply the  handbrake firmly.
– Engage the first gear , or put the selector lever to position  P for
those vehicles with an automatic gearbox.
– If you are towing a trailer, unhitch it from your vehicle.
– Take the vehicle tools and the spare wheel out of the luggage
compartment.
WARNING
Put the hazard warning lights on and place the warning triangle in posi-
tion. This is for your own safety and also warns other road users.
CAUTION
If you have to change the tyre on a gradient, block the wheel opposite the
wheel being changed by placing a stone or similar object under it to prevent
the vehicle from rolling away.
Note
Please observe legal requirements when doing so. 
Changing a wheel
Change the wheel as described below
– Remove the hub cap. Also see ⇒ page 262.
– Slacken the wheel bolts.
– Raise the vehicle with the jack at the corresponding point.
– Remove the wheel and then  mount the spare wheel.
– Lower the vehicle.
– Tighten the wheel bolts  firmly with the box spanner.
– Replace the hub cap. 
After changing a wheel
After changing the wheel there are still tasks to complete. – Put the tools and jack back in the luggage compartment.

Jump-starting
Jump leads
The jump lead must have a sufficient wire cross section. If the engine fails to start because of a discharged battery, the battery can
be connected to the battery of another vehicle to start the engine.
Jump leads
Jump leads must comply with standard  DIN 72553 (see cable manufactur-
er's instructions). The wire cross section must be at least 25  mm 2
 for petrol
engines and at least 35 mm 2
 for diesel engines.
Note
● The vehicles must not touch each other, otherwise electricity could flow
as soon as the positive terminals are connected.
● The discharged battery must be properly connected to the on-board net-
work.

Jump lead terminal connections
1. Switch off the ignition of both vehicles  ⇒ 
.
2. For vehicles without Start-Stop system :–
Connect one end of the  red jump lead to the positive  +
 termi-
nal of the vehicle with the flat battery  A ⇒ Fig. 204.
– Connect the other end of the  red jump lead to the positive ter-
minal  +
 in the vehicle providing assistance  B.
– Connect one end of the  black jump lead to the negative terminal
–
 of the vehicle providing assistance  B ⇒ Fig. 204.
– Connect the other end of the  black jump lead X
 to a solid met-
al component bolted to the engine block or to the engine block
itself of the vehicle with the flat battery. However, connect it to
a point as far as possible from the battery  A
.
3. For vehicles with Start-Stop system :
– Connect one end of the  red jump lead to the positive  +
 termi-
nal of the vehicle with the flat battery  A ⇒ Fig. 205.
– Connect the other end of the  red jump lead to the positive ter-
minal  +
 in the vehicle providing assistance  B.
– Connect one end of the  black jump lead X
 to a suitable ground
terminal, a solid piece of metal in the engine block, or to the en-
gine block  ⇒ Fig. 205.
– Connect the other end of the  black jump lead X
 to a solid met-
al component bolted to the engine block or to the engine block
itself of the vehicle with the flat battery. However, connect it to
a point as far as possible from the battery  A
.
4. Position the leads in such a way that they cannot come into contact with any moving parts in the engine compartment. 
Safety FirstOperating InstructionsPractical TipsTechnical Specifications  

284If and when
Starting
5. Start the engine of the vehicle with the boosting battery and let
it run at idling speed.
6. Start the engine of the vehicle with the flat battery and wait two or three minutes until the engine is “running”.
Removing the jump leads
7. Before you remove the jump leads, switch off the dipped beam headlights (if they are switched on).
8. Turn on the heater blower and heated rear window in the vehi- cle with the flat battery. This helps minimise voltage peaks
which are generated when the leads are disconnected.
9. When the engine is running, disconnect the leads in reverse or- der to the details given above.
Connect the battery clamps so they have good metal-to-metal contact with
the battery terminals.
If the engine fails to start, switch off the starter after about 10 seconds and
try again after about half a minute.
WARNING
● Please note the safety warnings referring to working in the engine
compartment  ⇒ page 233, Working in the engine compartment.
● The battery providing assistance must have the same voltage as the
flat battery (12V) and approximately the same capacity (see imprint on
battery). Failure to comply could result in an explosion.
WARNING (Continued)
● Never use jump leads when one of the batteries is frozen. Danger of
explosion! Even after the battery has thawed, battery acid could leak and
cause chemical burns. If a battery freezes, it should be replaced.
● Keep sparks, flames and lighted cigarettes away from batteries, dan-
ger of explosion. Failure to comply could result in an explosion.
● Observe the instructions provided by the manufacturer of the jump
leads.
● Do not connect the negative cable from the other vehicle directly to
the negative terminal of the flat battery. The gas emitted from the battery
could be ignited by sparks. Danger of explosion.
● Do not attach the negative cable from the other vehicle to parts of the
fuel system or to the brake line.
● The non-insulated parts of the battery clamps must not be allowed to
touch. The jump lead attached to the positive battery terminal must not
touch metal parts of the vehicle, this can cause a short circuit.
● Position the leads in such a way that they cannot come into contact
with any moving parts in the engine compartment.
● Do not lean on the batteries. This could result in chemical burns.
Note
The vehicles must not touch each other, otherwise electricity could flow as
soon as the positive terminals are connected.
