• Keep the vehicle st ationary using the bra kin g
peda l, for examp le a t traffic ligh ts.
• Do not press the acce le rato r pedal when doing
this.
• To prevent the vehicle from rolling when you start driving, set the pa rking brake when stop­
ping on steep
hills ¢.&. and ¢(Q).
• The parking brake will release a utomat ica lly
and the vehicle will start moving once yo u press
the acce le rato r pedal. Requirement: the d riv­
er's doo r mus t be closed.
Stopping/parking
If the selector lever is not in the "P" pos ition
whe n you open the d river's door, the vehicle
could roll. In vehicles with a conven ience key *,
the message :
Shift to P, otherwise vehicle can
roll away. Door s do not lock if lever is not in P
appe ars . A wa rning tone wi ll also sound.
• Press and hold the brake peda l¢ ,&. .
• Set t he par king brake.
• Select the "P" se lector lever posi tion .
Un der certai n circumstances, (such as dr iving in
the mo unta ins or towi ng a trailer), it may be use­
ful to switch temporar ily to the m an ual shift pro­
gr am in or der to ad ju st t he gears to the driv ing
cond it ions by hand ¢
page 88.
When parking on a level surface, s imp ly place the
se le ct or lever i n the "P" pos ition. On inclines, a c­
tivate the par king b rake first and then move the
se lector lever to the "P " posit ion ¢
page 81. Thi s
prevents the locking mechanism from being
l oaded too heavily and will make it easier to
move the selector lever out of the "P" position.
A WARNING
- The vehicle can roll even whe n the engi ne is
sw itched off .
- Unintended vehicle movement can lead to
serio us injuries.
- Never leave your veh icle with the engine
r u nning while in gear. If you must leave
your veh icle when the eng ine is r unning, set
t he par king brake and move the se lecto r lev ­
er to the "P " posi tion .

u. 00 .-< N l'­ N .-< 0 N > 00
-Power is still transferred to the wheels
when the engine is running at idle. To pre­
vent the vehicle from "creeping", you must keep your foot on the brake when the en­
gine is running and the selector lever is in
the "D", "S" or "R" position or "tiptronic"
mode is selected.
- Do not inadvertently press the accelerator
peda l when the vehicle is stopped if a gear is
engaged. Otherwise the risk of an accident
increases because the vehicle will start to
move immediately, even if the parking brake
is set.
- To reduce the risk of an accident, do not
press the acce lerator pedal when changing
the selector lever position while the vehicle is stationary and the engine is running.
- Never engage the "R" or "P" selector leve l
positions while driving. It could cause a
crash.
- Before driving down a steep slope, reduce
your speed and shift into a lower gear with
"ti ptron i c".
- Do not ride the brakes or press the brake
pedal too often or too long when driving
downhill. Constant braking causes the
brakes to overheat and substantially re­
duces braking performance, increases brak­
ing distance or causes complete failure of
the brake system.
- If you must stop on an incline, always hold
the vehicle in p lace with the foot brake or
park ing brake to prevent it from rolling
back.
- Never hold the veh icle on an incline with a
sl ip ping clutch. The clutch opens automati­
cally when it becomes too hot from the
overload. The
ml indicator light turns on
and a message appears
¢ page 89 when
the clutch is over loaded .
{LlJ) Note
- When stopping on an incline, do not try to
ho ld the vehicle in place by pressing the ac­
ce lerator pedal while a driving gear is se ­
l ected. This can cause the automatic trans ­
mission to overheat and can damage it. Set
Driving
the parking brake or press the brake pedal
to prevent the vehicle from rolling.
- Allowing the vehicle to roll when the engine
is stopped while the selector lever is in the
"N" position will damage the automatic
transmission, because it is not lubricated
under those circumstances
¢ page 3 78,
Towing with a tow truck.
- The transmission can overheat and be dam­
aged under certain driving and traffic condi­
tions such as frequent starts, creeping for a
long time, or stop-and-go traffic. When the
ml or. indicator light turns on, stop the
vehicle at the next opportunity and let the
transmission cool¢
page 89.
(D Tips
For safety reasons, the park ing brake only re­
l eases automatically when the driver's door is
closed.
Hill descent control
App lies to : vehicles wi th automatic transmiss ions
The hill descent control system assists the driver
when driving down hills.
Hill descent control is act ivated when the selec­
tor lever is in the "D" or "S" posit ion and you
press the b rake pedal. The transmission auto ­
matically se lects a gear that is suitab le for the
hill. Hill descent contro l tries to ma inta in the
speed achieved at the time of braking, within
physical and technica l limitations. If may still be
necessary to adjust the speed with the brakes.
Because hill descent control cannot shift down
farther than 3rd gear, it may be necessary to
shift into tiptronic mode in very steep areas . In
th is case, shift into 2nd or 1st gear in t iptronic
mode to use the engine's braking force to rel ieve
the brakes.
Hill descent control switches
off once the hill lev­
els out or you press the accelerator pedal.
On vehicles with a cruise control system*
¢ page 120, hill descent control is also activated
when the speed is set .
.,,.
87

Driving
& WARNING
Hill descent control cannot overcome phys ical
limitations, so it may not be able to maintain
a constant speed under all condit ions. Always
be ready to apply the brakes .
Manual shifting (tiptronic mode)
Applies to: vehicles with automatic transmissions
The tiptronic mode allows the driver to shift the
gears manually.

sition into the tiptronic shift gate .
The tra nsmission a utomatically sh ifts up or dow n
before cr itical engine speed is reac hed.
Applies to: RS models: when accelerating, the
transm iss ion does
not au tomatically shift to the
next gear short ly before the maxim um permitted
engine RP M is re ached. Shift to the next highest
gear at the right time.
The tra nsmission on ly allows manual shifting
whe n the engine speed is w ith in the perm itted
r a nge.
Kick-down
Applies to: vehicles with automatic transmissions
Kick-down enables maximum acceleration.
When you p ress the accelerator pedal down be­
yo nd the res istance point (called kick-down), the
automat ic transmission downshifts into a lower
gear, depending on vehicle s peed and engine
RPM .
It shifts up into the next higher gear once
t h e maximum specified engine RPM is reached .
Applies to: RS models: in tipt ronic mode, the
transm iss ion does
not automa tic ally shift down
i nto a lower ge ar. If yo u m ust accelera te, for ex ­
ample to pass a vehi cle, you mus t sh ift manually .

page 95, fig. 98. By doing this, a large amount
of the kinetic energy is recovered and may be
stored as electric energy in the high-voltage bat­
tery . The conventional brakes are also activated
when the brakes are pressed very hard.
The strength of recuperation can depend on the
following factors:
