Loosening/tightening wheel boltsFig. 167
Loosening the wheel bolts
›
Insert the wheel wrench onto the wheel bolt to the stop. Use the associated
attachment for the anti-theft wheel bolts » Fig. 166 on page 143 .
›
To loosen the screws , grasp the key end and turn the screw about one turn
rotation in the direction of the arrow » Fig. 167.
›
Totighten the screws , grasp the key end and turn the screw about against
the direction of the arrow » Fig. 167, until it is tight.
WARNINGIf it proves difficult to undo the bolts, carefully apply pressure to the end of
the wrench with your foot. Keep hold of the vehicle when doing so, and
make sure you keep your footing - danger of injury.
Raising the vehicle
Fig. 168
Jacking points for the jack
Fig. 169
Attach lifting jack
Before the vehicle is raised, please take note of the safety instructions »
.
In order to raise the vehicle, the jack from the tool kit is to be used. Position
the car jack at the jacking point closest to the flat tyre.
The jacking points are located on the lower sill » Fig. 168.
›
Position the base plate of the jack with its full area resting on level ground
and ensure that the jack will fit in the jacking point when raised » Fig. 169 -
.
›
Use the crank to raise the jack until its pawl covers the jacking
point » Fig. 169 -
.
›
Raise the vehicle until the wheel is a little off the floor.
WARNINGThe following instructions must be observed, otherwise there is risk of in-
jury.■
Ensure the vehicle cannot unexpectedly roll away.
■
Always ensure the base plate of the lifting jack cannot slip.
■ Place a wide and stable base material under the jack if on a loose surfa-
ces (e.g. gravel).
■ Place an anti-slip base material (e.g. a rubber mat) under the jack if on a
smooth surface (e.g. cobblestones).
■
Always raise the vehicle with the doors closed.
■
Never position any body parts (e.g. arms or legs) under the vehicle while
the vehicle is raised.
■
When the vehicle is raised, never start the engine.
CAUTION
It is important to ensure that the jack is correctly positioned against the bar of
the lower beam - otherwise there is a risk of damage to the vehicle.144Do-it-yourself
If the tyre pressure is 1.3 bar or more›Set the tyre pressure back to the correct value » page 137.›
Continue driving carefully to the nearest specialist garage at a maximum
speed of 80 km/h (50 mph).
WARNINGA tyre filled with sealant has the same driving characteristics as a standard
tyre. The following guidelines must be observed.■
Do not drive faster than 80 km/h (50 mph).
■
Avoid accelerating at full throttle, sharp braking and fast cornering.
Jump-starting
Introduction
This chapter contains information on the following subjects:
Jump-starting using the battery from another vehicle
147WARNING■ The following instructions must be followed at all times when working on
the engine compartment » page 128.■
When handling the vehicle battery, the following warnings must be ob-
served » page 133 .
■
A discharged vehicle battery may already freeze at temperatures just be-
low 0 °C. If the battery is frozen, do not carry out a jump start with the bat-
tery of another vehicle – risk of explosion and injury!
■
Never jump-start vehicle batteries with an electrolyte level that is too low
– risk of explosion and caustic burns.
Jump-starting using the battery from another vehicleFig. 171
Start help:
- Discharged battery,
- power-supplying battery /
ground point of the engine for the START-STOP system
Fig. 172
Earth point and positive terminal on vehicles with the vehicle
battery in the luggage compartment
Read and observe
on page 147 first.
If, because of a discharged battery, it is not possible to start the engine, the
battery of another vehicle can be used to start the engine. To do this, jump-
start cables are required which have a sufficiently large cross-section and in-
sulated terminal clamps.
The rated voltage of the two batteries must be 12 V. The capacity (Ah) of the
power-supplying battery must not be significantly lower than the capacity of
the discharged battery.
The jump-start cables must be attached in the following sequence.
›
Attach clamp
1
to the positive terminal of the discharged battery.
›
Attach clamp
2
to the positive terminal of the power-supplying battery.
147Emergency equipment and self-help
›Attach clamp 3 to the negative terminal of the power-supplying battery.›For vehicles
with the START-STOPsystem, attach clamp 4 to the earth point
of the engine A
» Fig. 171 .
›
For vehicles without the START-STOPsystem, attach clamp
4
to a solid
metal part firmly attached to the engine block or directly to the engine block.
Installation location of the positive terminal and the earth point in vehicles
with the vehicle battery in the luggage compartment
The positive terminal
B
is located under a cover in the engine compartment
» Fig. 172 .
›
Unlock the lock buttons of the cover in the direction of arrow
1
and remove
the cover in the direction of arrow
2
.
›
Clamp the positive terminal of the jumper cable to the position
B
» Fig. 172 .
›
Clamp the negative terminal of the jumper cable to the earth point of the en-
gine
A
or on a metal part firmly connected to the engine block or directly on
the engine block.
Starting engine
›
Start the engine on the vehicle providing the power and allow it to idle.
›
Initiate the starting process in the vehicle with the discharged battery.
›
If the engine does not start within 10 s, then cancel the starting procedure
and repeat after half a minute.
›
Remove the jump start cables in the reverse order as attachment.
WARNING■
Never clamp the jump cable to the negative terminal of the discharged
battery - risk of explosion.■
The non-insulated parts of the terminal clamps must never touch each
other – there is a risk of short circuit!
■
The jump-start cable connected to the positive terminal of the battery
must not come into contact with electrically conducting parts of the vehicle
– there is a risk of short circuit!
■
Position the jump cables so that they cannot be caught in rotating parts
in the engine compartment - danger of injuries and the risk of vehicle dam-
age.
Towing the vehicle
Information about the towing process
Fig. 173
Braided tow rope / Spiral tow rope
To tow with a tow rope, only use a braided synthetic fibre rope » Fig. 173 -
»
.
Attach the tow rope or the tow bar to the towing eyes at the front
» page 149 , towing eyes at the rear » page 149 or to the towing device of
the trailer device » page 111 .
Conditions for towing. Cars with automatic gearboxes must not be towed with the rear wheels
raised - there is a risk of gearbox damage!
If the gearbox has no oil, your vehicle must be towed with the front axle
raised clear of the ground or on a breakdown vehicle or trailer.
The maximum towing speed is 50 km/h.
The vehicle must be transported on a special breakdown vehicle or trailer
if it is not possible to tow the vehicle in the way described or if the towing
distance is greater than 50 km.
Driver of the tow vehicle
›
On vehicles with manual transmission , engage gear slowly when starting.
›
On vehicles with automatic transmission , accelerate with particular care.
›
Only then approach correctly when the rope is taut.
Driver of the towed vehicle
›
If possible, the vehicle should be towed with the engine running. The brake
booster and power steering only operate if the engine is running, otherwise
much greater force has to be applied to the brake pedal and more power has
to be expended for steering.
