At the operating unit
1. Switch on the ignition (do not start the engine).
2. Press and hold down the two outer HomeLink buttons
⇒page 154, fig. 171 until the indicator diode
⇒ page 154, fig. 171 begins to flash after about
20 seconds. This procedure will delete the standard
factory settings and does not need to be repeated when
programming the other buttons.
3. Press the particular Home Link button which you would
like to program.
4. Wait until the diode begins to flash. The HomeLink module now remains in training mode for 5 minutes.
5. Now step in front of your vehicle with the original hand-
held transmitter for the garage door opener or any other
device you wish to assign to the HomeLink control
button.
At the radiator grille
6. Hold the original hand-held transmitter at or near the
centre of your car's radiator grille ⇒ page 154, fig. 172.
7. Press the activator button on the original hand-held
transmitter .
8. As you do so, watch the tu rn signals on your vehicle.
HomeLink confirms successful programming by flashing
all four turn signals three times.
9. If the turn signals fail to flash three times, repeat the procedure with the transmitter held at a different
distance from the radiator grille.
The proper distance between the hand-held transmitter and the
HomeLink module at the radiator grille depends on the system you
want to train. It may re quire several attempts.
The turn signals will flash once if the time limit for the programming
mode has been exceeded. In this case the programming procedure
needs to be performed again. Repeat the sequence at the operating
unit starting with step 3.
The programming instructions above also apply to th e other control
buttons. Start with step 3 if yo u wish to proceed and program the
other two buttons.
If the garage door or other devices st ill fail to be activated with the
HomeLink control buttons after programming is completed, it is
possible that these systems might be working with a rolling code
instead of the normal fixed security code. If this is the case, a rolling
code programming is required in addition to the steps described
above. ⇒page 155Applies to vehicles: with HomeLinkRolling code programming
Some devices require rolling code programming of the
HomeLink universal transmitter.Identifying a rolling code
– Press the already programmed HomeLink button again
and hold it down.
–Watch HomeLink diode ⇒ page 154, fig. 171. If the
diode starts flashing rapidly and turns into a constant
light after about 2 seconds, this indicates that the device
you wish to operate (e.g. a garage door opener) is
equipped with a rolling code.
– Program the rolling code as follows:

vary depending on the type of garage door opener.
– Press the programming button on the door drive unit (this will normally cause a “programming mode indicator
lamp” on the unit to light up). You now have about 30
seconds to start and complete the programming of the
HomeLink control button on the operating unit.
Programming at the operating unit in the
headliner
– Press and release the already programmed HomeLink button.
– Press the HomeLink button again to complete rolling code programming.After programming at the operating unit in the headliner, the
garage door opener should recognize the HomeLink signal and
respond when the HomeLink button is pressed. Now the other
control buttons can be programmed as required.
Note
•
Having a second person assist you makes programming of the
rolling code easier and faster. For some makes of garage door
openers the HomeLink button may have to be pressed a third time
to complete the training sequence.
•
If you encounter problems programming the rolling code you
may find helpful information in the operating instructions of the
garage door opener or other device you wish to operate.

– Fasten your seat belt correctly. Make sure that your passengers do the same ⇒page 170.What affects driving safety?
Safety on the road is directly related to how you drive, and
can also be affected by the passengers in the vehicle.The driver is responsible for th e safety of the vehicle and all
its occupants. If your ability to drive is impaired in any way,
you endanger yourself and other road users ⇒. There-
fore:
– Do not let yourself be distracted by passengers or by using a mobile phone, etc. – Never drive when your driving ability is impaired (by
medication, alcohol, drugs, etc.).
– Obey all traffic regulations and speed limits and always maintain a safe distance to the vehicle in front.
– Always adjust your speed to suit the road, traffic and weather conditions.
– Take frequent breaks on long trips. Do not drive for more than two hours without a stop.
– If possible, avoid driving when you are tired or stressed.
WARNING
•
Distractions while driving or any kind of impairment to your
driving ability increase the risk of accident and injury.
•
Do not store loose objects on the dashboard. These objects
could fly around the interior when the vehicle is moving (under
acceleration or whilst cornering) and distract the driver – this
could lead to an accident.

Driving tips

Technical data
•
The airbag system can only be acti vated once; if the airbag has
been triggered, the system must be replaced. Should the airbag
system or airbag modules have to be replaced, the qualified work-
shop carrying out the replacement will document all details in the
appropriate section of the Service Schedule.
•
If you sell the vehi cle, please remember to pass on the
complete Service Wallet to the ne w owner. If any of the airbags
have been deactivated, it is impo rtant that the new owner is also
given the relevant documents.
•
The relevant safety requiremen ts must be observed when the
vehicle or components of the airbag or belt tensioner systems are
scrapped.
•
In an accident in which one or more airbags are triggered the
alternator and the starter are - for safety reasons - both discon-
nected from the battery via a pyrotechnic circuit breaker.
−Any repairs to the pyrotechnic circuit breaker must always
be performed by a qualified workshop (accident risk).
− The relevant safety requirements must be observed when
the vehicle or the circuit breaker are scrapped.
When are the airbags triggered?
The airbag system is triggered in collisions with a severe
impact.The airbag system is designed so that the airbags for the driver and
front passenger are triggered in a severe frontal collision .
In severe side collisions the side airbags on th e impact side of the
vehicle are triggered together with the head-protection airbag.
The front airbags, side airbags and one of the head-protection
airbags may be triggered together in certain types of accident. The airbag system is
not triggered in minor frontal or side collisions,
or in rear collisions or if the ca r overturns. In these situations the
occupants are protected by wearing the seat belts.
Factors determining the triggering response
It is not possible to define the exact triggering response of the
airbag system in all possible situations, since the circumstances in
different types of accident will vary considerably. Important factors
include, for example, the nature (hard or soft) of the object which
the car hits, the angle of impact, vehicle speed and so on.
Whether the airbags are triggered depends primarily on the vehicle
deceleration rate resulting from the collision. By processing the
signals from the sensors located in the vehicle, the electronic
control unit is immediately able to evaluate the severity of the colli-
sion and activate the restraint syst ems accordingly. If the decelera-
tion rate is below the predefined reference value in the control unit
the airbags will not be triggered, even though the accident may
cause extensive damage to the car.
Note
The airbag releases a fine dust when it inflates. This is quite normal
and does not mean there is a fire in the vehicle.

terminal must not touch metal parts of the vehicle: this can cause
short circuiting.
•
Do not bend over the batteries – risk of acid burns.
•
The screw plugs on the battery ce
lls must be screwed in firmly.
•
Keep sparks, flame and lighted cigarettes away from batteries:
the gases given off can cause an explosion.
•
If jump-starting another vehicle, position the jump leads in
such a way that they cannot come into contact with any moving
parts in the engine compart ment of the other vehicle.Caution
Please note that the above method of connecting the leads is meant
for jump-starting your vehicle. If jump-starting another vehicle, you
should not connect the negative lead (–) to the negative terminal of
the discharged battery, but directly to the engine block or a solid
metal part bolted to the engine bl ock. If the battery of the other
vehicle does not have a gas vent, there is a risk that a mixture of
oxygen and hydrogen gas can accumulate and cause an
explosion.Tow-starting and towing awayGeneral notes
Points to observe when tow-starting or towing awayIf you use a towrope:
Notes for the driver of the towing vehicle
– The towrope must be taut before driving off. – Engage the clutch very gently when starting to move; on
vehicles with automatic gearbox press the accelerator
slowly.
Notes for the driver of the towed vehicle
– The ignition should be switched on so that the turn signals, horn, windscreen wipers and washers can be
used. Please ensure that the steering wheel is unlocked
when you switch on the ignition, and that it moves freely.
–Put gear lever in neutral (manual gearbox) or move
selector lever to position N (automatic gearbox).
– The brake servo and power steering only work when the engine is running. Considerably more effort is required
on the brake pedal and steering wheel when the engine
is switched off.
– Ensure that the towrope remains taut at all times when towing.
Towrope or towbar
It is easier and safer to tow a vehicle with a tow bar. You should only
use a tow rope if you do not have a towbar.
A towrope should be slightly elasti c to reduce the loading on both
vehicles. It is advisable to use a towrope made of synthetic fibre or
similar material.
Attach the tow-rope or tow-bar only to the towing anchorages
intended for this purpose ⇒page 268 or ⇒page 269 .
Driving technique
Towing requires some experience – especially when using a
tow rope . Both drivers should be familiar with the technique required
for towing. Inexperienced drivers sh ould not attempt to tow-start or
tow away another vehicle.
