Applies to vehicles: with mult it ron ic® Contin uously Variable Transm iss io n (CVT )
Dynamic shift program (DSP)
The multitronic® transmission is electronically
controlled .
The transmission selects the appropriate gear ratio (upshifts and
downshiftsl automatically based on preset driving programs .
The transmission will select one of the
economy programs when
you drive at a steady speed or a gradually changing speeds without heavy acceleration. This gives best fuel efficiency, with early
upshifting and delayed downshifting .
The transmission will automatically select th e
sporty shift programs
when you drive at higher speeds, or with heavy acceleration and
fr equ ently changing speeds. Upshifts are d elay ed to make full use
of engine power. Downshifting takes place at higher engine speeds
than in the economy programs .
The selection of the most suitable shift program is a continuous,
automatic process . The driver can also make the transmission
switch to a sporty program by
quickly pressing down the gas pedal.
This causes the transmission to shift down into a lower gear ratio
a n d makes quick acceleration possible (to pass another vehicle) You
do not need to press the gas pedal into the kickdown range. After
the transmission has upshifted, the original prog ram is selected
according to your driving style .
An additional shift program allows the automatic transmission to select the prop er gear for uphill and downhill gradients .
This prevents the transmission from shifting up and down unneces ­
sarily on hills. The transmission
will shift down to a lower gear ratio
when the driver presses the brake pedal on a downhill gradient . This
makes use of the braking effect of the engine without the need to
shift down manually.
If you are driving in hills and mountains, the transmission will
continuously adjust the g ear ratio to the road grade . If you press the brake pedal when driving downhill, the transmission will downshift
automatically. This increases the braking effect
of the engine.
If the cruise control is on when you are trave.ling downhill, the trans­
mission will automatically select a lower gear ratio in order to main ­
tain the set vehicle speed. This will cause the engine speed to
increase. •

tiptronic ® manual shift program
Using the manual shift program (tiptronic®) you can
manually shift between seven pre -programmed gear
ratios (transmission positions).

To d ownshift
- Pu sh the lever to the mi nus positio n Q.
When accelerating, the transmission wi II a utomatica I ly shift into the
next higher gear before the engine reaches the maximum RPM .
When accelerating, if you apply a light throttle, the tiptronic® wil l
automatically shift into the next higher gear to save fuel. If you app ly
a heavy throttle, the transmission will stay in gear engaged until
near maximum RPM are reached, or until the driver manually shifts
into a higher gear .
If you take your foot off the accelerator peda l when driving down a
steep incline, the tiptronic ® wi ll downshift from the selected gear
into the next lower gear based on road speed and engine RPM . The
automatic downshifting is interrupted as soon as you apply throttle
again .
[ i ] Tips
• When you shift into the next lower gear, the engine will down ­
shift only when there is no possibility of over-revving.
• When the kick -down comes on, the transmission wi ll sh ift down
to a lower gear depending on vehicle and engine speeds.
• The tiptronic® is inoperative when the transmission is in the fai l­
safe mode .•

What impairs driving safety?
Safe driving is directly related to the condition of the
vehicle, the driver as well as the driver's ability to concen­
trate on the road without being distracted.
The driver is responsible for the safety of the vehicle and all
of its occupants. If your ability to drive is impaired, safety
risks for everybody in the vehicle increase and you also
Controls and equip­
ment Safety first Vehicle operation
become a
hazard to everyone else on the road ~& .There ­
fore:
- Do not let yourself be distracted by passengers or by
using a cellular telephone.
- NEVER drive when your driving ability is impaired (by
medications, alcohol, drugs, etc.I.
- Observe all traffic laws, rules of the road and speed limits
and plain common sense.
- ALWAYS adjust your speed to road, traffic and weather
conditions.
- Take frequent breaks on long trips. Do not drive for more
than two hours at a stretch.
- Do NOT drive when you are tired, under pressure or when
you are stressed.
& WARNING
Impaired driving safety increases the risk of serious personal
injury and death whenever a vehicle is being used. •

Safety belts
General notes
Always wear safety belts!
Wearing safety belts correctly saves lives!
This chapter explains why safety belts are necessary, how
they work and how to adjust and wear them correctly.
- Read all the information that follows and heed all of the
instructions and WARNINGS.
& WARNING
Not wearing safety belts or wearing them improperly increases
the risk of serious personal injury and death.
• Safety belts are the single most effective means available to
reduce the risk of serious injury and death in automobile acci­
dents. For your protection and that of your passengers, always
correctly wear safety belts when the vehicle is moving.
• Pregnant women, injured, or physically impaired persons must
also use safety belts . Like all vehicle occupants, they are more
likely to be seriously injured if they do not wear safety belts. The
best way to protect a fetus is to protect the mother -throughout
the entire pregnancy. •
Number of seats
Your vehicle has a total of four seating positions : two in the front
and two in the rear. Each seating posi tion has a safety belt .
Controls and equip­ ment Safety first
Vehicle operation
& WARNING
Not wearing safety belts or wearing them improperly increases
the risk of serious personal injury and death.
• Never strap more than one person, including small children,
into any belt. It is especially dangerous to place a safety belt over
a child sitting on your lap.
• Never let more people ride in the vehicle than there are safety
belts available.
• Be sure everyone riding in the vehicle is properly restrained
with a separate safety belt or child restraint. •
Safety belt warning light ~
Your vehicle has a warning system to remind you about
the importance of buckling-up.
Before driving off, always:

The warning light~ in the instrument cluster lights up when the
ignition is switched on as a reminder to fasten the safety belts. In
addition, you will hear a warning sound.
After the ignition is switched on, the warning tone will come on for about 6 seconds a long w ith a-~ warning light in the instru ment
cluster if the driver has not fastened his safety belt . As soon as the
driver has fastened his safety belt, the warning tone will stop and
the warning light will go out .
I f the driver has not buckled -up within about 24 seconds after the
warn ing tone has stopped, the warn ing tone will sound again for
about 6 seconds. The warning tone will sound repeated ly for about
6 seconds at 24 second intervals unti l the driver has buckled-up . The
safety belt warning system is active for about 5 minutes and during
this time the wa rning light in the instrument c luster will stay on.

Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create ve ry strong forces for pe ople ri ding
in vehicles.

The physica l principles are simple. Both the vehicle and the passen­
gers possess energy which varies with vehicle speed and body
we ight . Engineers call this energy "kinetic energy ."
The higher the speed of the vehicle and the greater the vehicle's
we ight, the mo re energy that has to be "absorbed" in the crash .
Vehicle speed is the most significant factor. If the speed doub les
from 15 to 30 mph (25 to 50 km/h), the energy increases 4 times!

-Safety belts ___ .:,__ _____________________________________ _
Automatic safety belt retractors
Every safety belt is equipped with an automatic belt retractor on the
shoulder bel t. This featu re locks the bel t when the belt is pulled out
fast, during hard braking and in an accident. The belt may also lock
when you drive up or down a steep hill or through a sharp curve. During normal driving the bel t lets you move freely.
Safety belt pretensioners
The safety belts are equipped with a belt pretension er that helps to
tighten the safety belt and remove slack when the pretensioner is
activated. The function of the pretensioner is monitored by a
warning light:::::, page
20, "Airbag system @;".
Switchable locking feature
Every safe ty belt except the one on the driver seat is equipped with
a switchable locking feature that must be used when the safety belt
is used to attach a child seat . Be sure to read the important informa­
tion about this feature:::::, page
200.
& WARNING
Improperly positioned safety belts can cause serious injury in an
accident :::::,
page 164, "Safety belt position" .
• Safety belts offer optimum protection only when the seat back
is upright and belts are properly positioned on the body.
• Never attach the safety belt to the buckle for another seat.
Attaching the belt to the wrong buckle will reduce safety belt
effectiveness and can cause serious personal injury.
• A passenger who is not properly restrained can be seriously
injured by the safety belt itself when it moves from the stronger
parts of the body into critical areas like the abdomen.
• Always lock the convertible locking retractor when you are
securing a child seat in the vehicle :::::,
page 202. •
Safety belt position
Correct belt position is the key to getting maximum
protection from safety belts.

in. WARNING
Improperly positioned safety belts can cause serious personal
injury in an accident .
• The shoulder belt portion of the safety belt must be positioned
over the middle of the occupant's shoulder and never across the
neck or throat.
• The safety belt must lie flat and snug on the occupant's upper
body
:::::> fig. 168. Pull on the belt to tighten if necessary.
• The lap belt portion of the safety belt must be positioned as
low as possible across pelvis and never over the abdomen. Make
sure the belt lies flat and snug :::::, fig. 168. Pull on the belt to
tighten if necessary.
• A loose-fitting safety belt can cause serious injuries by shifting
its position on your body from the strong bones to more vulner-
able, soft tissue and cause serious injury. ..,.
