Technical Data The airbag develops enormous forces when triggered, which can lead to injuries if
the sitting position or seated position is not correct ⇒ in “Important safety
information regarding the front airbag system” on page 141.
Important safety information regarding the front airbag system
Correct use of the airbag system considerably reduces the risk of
injury!
WARNING
•
Never transport children on the front seat of a vehicle without using a
proper restraint system. If airbags are deployed in the event of an accident,
the child might suffer severe or even fatal injuries!
•
For the driver and front passenger it is important to maintain a distance
of at least 25 cm from the steering wheel or dash panel ⇒fig. 152. Not main-
taining this minimum distance will mean that the airbag system will not be
able to properly protect you - hazard! The front seats and the head restraints
must always also be correctly adjusted to match the body size of the occu-
pant.
•
It is essential to always switch off ⇒page 145, “Deactivating airbags” the
front passenger airbag when attaching a child safety seat on the front
passenger seat where the child is seated with its back facing in direction of
travel (in some countries also when the child is facing the direction of travel). If this is not done, there is a risk of the child suffering severe or even fatal
injuries if the front passenger airbag is deployed. In certain countries
national legal provisions also require that the side or head passenger
airbags be deactivated. When transporting a child on the front passenger
seat, please comply with the appropriate national regulations regarding the
use of child safety seats.
•
There must not by any further persons, animals or objects positioned
between the front seated occupants and the deployment area of the airbag.
•
The steering wheel and the surface of the airbag module in the dash
panel on the passenger side must not be stuck onto, covered or modified in
any other way. These parts should only be cleaned with a dry cloth or a cloth
moistened with water. No objects such as cup holders, mobile phone
mounts, etc. may be attached to the covers of the airbag modules or be
located within the immediate area.
•
No modifications of any kind may be made to parts of the airbag system.
Any work on the airbag system including installing and removing system
components because of other repair work (e.g. removing the steering
wheel) must only be carried out by a specialist garage.
•
Never carry out changes on the front bumper or on the body.
•
Never place any objects on the surface of the dash panel on the front
passenger side.

– Pull off the full wheel trim/cap from the wheel hub or cap from the
safety wheel bolt.
– Insert the adapter with its toothed side fully into the inner toothing
of the safety wheel bolt right down in such a way that only the
outer hexagon is jutting out ⇒page 210, fig. 199.
– Insert the wheel wrench fully onto the adapter .
– Slacken the wheel bolt, or tighten it firmly ⇒page 209.
– Reinstall the full wheel trim/wheel cap after removing the adapter or
place the cap onto the safety wheel bolt.
–Have the tightening torque checked w i t h a t o rq u e w re n c h a s s o o n a s
possible. Steel and light alloy wheels must be tightened to a tightening
torque of 120 Nm.The safety wheel bolts on vehicles fitted with them (one safety wheel bolt per
wheel) can only be loosened or tighten up by using the adapter provided.
It is meaningful to note the code number hammered into the rear side of the
adapter or the rear side of the safety wheel bolts. You can obtain a replacement
adapter from a specialist garage, if necessary, by quoting this number.
We recommend that you always carry the adapter for the wheel bolts with you in
the vehicle. It should be stowed in the vehicle tool kit.
Caution
•
Damage can occur to the adapter and safety wheel bolt if the safety wheel bolt
is tightened up too much.
•
On steel wheels, the theft-deterrent wheel bolt must always be installed in the
hole, which is close to the valve. Otherwise the full wheel trim cannot be mounted
and the full wheel trim can be damaged during the assembly.Note
The set of safety wheel bolts can be obtained from a specialist garage.
Jump-startingInitial stepsYou can use the battery of another vehicle for jump-starting yours if the engine
does not start because the battery on your vehicle is flat. You will require jump-start
cables for this purpose.
Both batteries must have a rated voltage of 12 V. The capacity (Ah) of the battery
supplying the power must not be significantly less than the capacity of the
discharged battery in your vehicle.
Jump-start cables
Only use jump-start cables which have an adequately large cross-section and insu-
lated terminal clamps. Please pay attention to the manufacturer's instructions.
Positive cable - colour coding in the majority of cases red.
Negative cable - colour coding in the majority of cases black.
WARNING
•
A discharged battery may already freeze at temperatures just below 0°C.
In case of frozen battery carry out no jump-starting - risk of explosion! Also
after thawing of the battery there is a risk of caustic burns due to leaking
acid. Replace the frozen battery.
•
Please pay attention to the warning instructions relating to working in
the engine compartment ⇒page 185.Note
•
There must not be any contact between the two vehicles otherwise current may
flow as soon as the negative terminals are connected.
•
The discharged battery must be properly connected to the system of the
vehicle.
•
Switch off any installed telephone and also pay attention to the instructions for
use of the telephone in such a situation.
