electrical equipment such as exterior lights
will switch off as well when that happens.
Switching engine off
Applies to veh icles: w ith Conven ience key
~ Bring your vehicle to a complete stop.
~ Move the selector lever to the P or N position.
~ Press the I START ENGIN E STOPI button
¢page 87, fig. 10 2.
Steering lock
The steering locks when you turn the engine off
using the
!START ENGINE STOP ! button and
open the driver 's door. The locked steering helps
prevent vehicle theft.
Emergency off
If necessary, the engine can be switched off with
the s ele ctor lever in the R or D/S position. The
engine stops if you press and hold the
!START ENGINE STOP! button at speeds below
6 mph (10 km/h) and press the brake pedal.
A WARNING
- Never turn off the engine before the vehicle
has come to a complete stop. The full func­
t ion of the brake booster and the power
steering is not guaranteed. You must use
more force to turn or brake if necessary. Be­
cause you cannot steer and brake as you
usually would, this could lead to crashes
and serious injuries.
- For safety reasons, you should always park
your vehicle with the selector lever in P.
Otherwise, the vehicle could inadvertently
roll away .
- The radiator fan can continue to run for up
to 10 minutes even after you have turned
off the engine and removed the ignition key.
The radiator fan can also turn on again if the
engine coolant heats up because of intense
sunlight or heat build-up in the engine com­
partment.
- Always take the key with you whenever you
leave your vehicle. Otherwise, the engine
could be started or electrical equipment
88
such as the power windows could be operat­
ed. This can lead to serious injury.
- Never leave children or persons requiring as ­
sistance unattended in the vehicle. The
doors can be locked using the remote trans­
mitter, preventing people from escaping
from the vehicle on their own in the event of
an emergency. Depending on the time of
year, people inside the vehicle can be ex­
posed to very high or very low tempera­
tures.
0 Note
If the engine has been under heavy load for
an extended period, heat builds up in the en­
gine compartment after the engine is switch­
ed off -there is a risk of damaging the engine.
Allow the engine to run at idle for about two
minutes before switching it off.

A WARNING
If a drive range is engaged with the vehicle
stationary and the engine running, you must
in no instance accelerate care lessly. Other­
w ise the vehicle will start to move immediate­
ly -risk of an accident.
(D Tips
- If the parking brake is app lied with the igni­
tion switched off, the indicator lights in the
switch and. (USA models)/ . (Cana-
da models) in the instrument cluster will go
out after a ce rtain per iod of t ime.
- Occasiona l noises whe n the parking b rake is
applied and released are normal and are not

When stopp ing at a t raffic sig na l or s topping in
c ity traff ic on vehicles with an automat ic t rans ­
mission, the pa rking brake can be applied . The
vehicle does not have to be held with the foot­ brake. The parking brake eliminates the tendency
to c reep w ith a dr ive range engaged . As soon as
you drive off as usual, the parking brake is re­
leased automat ica lly and the vehicle starts to
move.
Starting on slope s
When starting on incl ines, the starting assist pre­
vents the vehicle from un intent iona lly rolling
back. The braking force of the parking brake is
not re leased u nti l sufficient dr iv ing fo rce has
been built up at the wheels.
@ Tips
For safety reasons, the park ing brake is re­
l eased automatically on ly when the d river's
safety be lt is engaged in the b uckle.
Starting off with a trailer
To prevent rolling bock unintentionally on on in­
cline, do the following:
" Keep the switch pu lled and depress the acceler­

that you are developing enough driving force at
the wheels by depressing the accelerator .
Depending on the weight of the r ig (vehi cle and
tra iler) and the severity of the incline, you may
ro ll backwards as you start . You can prevent roll ­
ing backwards by holding the parking brake
switch pulled out and accelerating -just as you
wou ld when starting on a hill with a conventiona l
h and brake .
Emergency braking
In the event that the conven tional brake system
fails or locks .
~ In an emergency, pull the sw itch and cont inue
to pull it to slow your veh icle down with the
parking b rake.
~ As soon as you release the switch or accelerate,
the b raking process stops .
If you pull the sw itch and hold it above a speed of
about 5 mph (8 km/h) , the eme rgency braking
function is in it iated . The vehicle is braked at all
four wheels by activating the hydraulic brake sys­
te m. T he b rake perfo rman ce is sim ila r t o making
an em ergen cy sto p ~ ,& .
In o rder not to activate the emergency brak ing by
mista ke, an audib le wa rn ing tone (buzze r)
sounds w hen the sw itch is p ulled. As soon as t he
sw itch is rele ased, or the acce le ra to r p edal is de­
p ressed, eme rgency bra king stops.
A WARNING
Emergency bra king should only be use d in an
emergency, w hen the normal foot brake has
fai led or the bra ke pedal is obstructed . Using
the par king b rake to perfo rm emergency
brak ing will slow your vehicle down as if you
had made a full bra ke ap plication . The laws of
physics cannot be suspended even wi th ESC
a n d its associated components (A BS, ASR,
E DS). In c orn ers and when road or weath er
c ondi tions are bad, a full brake ap plication
c an ca use the vehicle to sk id or the rear end to
break away· r isking an accident .

Driving
-For reasons of safety, cruise control should
not be used in the city, in stop-and-go traf­
fic, on twisting roads and when road condi­
tions are poor (such as ice, fog, gravel, heavy rain and hydroplaning) -you could
have an accident.
- Switch the cruise control off temporarily when driving in turning lanes, highway exits
or in construction zones.
- Please note that unconsciously "resting"
your foot on the accelerator pedal causes cruise control not to brake . This is due to
the control system being overridden by the
driver's acceleration.
- Never use the cruise control when driving
off-road or on unpaved roads. The cruise
control is intended for use only when the ve­
hicle is being operated on paved roads, and
is not suitable for use off-road or on un­
paved roads.
- If a brake system malfunction such as over­
heating occurs when the cruise control sys­
tem is switched on, the braking function in
the system may be switched off. The other
cruise control functions remain active as
long as the indicator light
tii;(O~i4 (US mod­
el)/lil (Canadian model) is on .

"'To turn on EV mode, press the 1.,,.,, 1 button. The
indicator light in the button will turn on. The
• indicator light also turns on in the instru­
ment cluster disp lay.
The functions and operating modes described be­ low are selected automat ically by the vehicle con­
trol system, depending on the vehicle operating
status. This ensu res that the vehicle is always in
the correct operating mode. One exception is the
enhanced elect ric driving mode
(EV mode), wh ich
is activated by the driver ¢
page 100.
Driving with the combustion engine
The vehicle is powered by the combustion eng ine.
The high voltage battery is charged simultane­
ously, if needed .
Full acceleration (boost)
In full acceleration, the vehicle is powered by both the combustion eng ine and the electric mo­
tor . This operating mode is called
Boost and is
only available for a short amount of time because
it uses so much energy. Ava ilability depends on
the high voltage battery charge level.
The boost operating mode is act ivated by press­
ing the accelerator pedal all the way down.
Electric driving
The vehicle can be driven completely electrically
depending on the high voltage battery charge
level and the driving resistance. The combust io n
engine tu rns off at that time.
100
The combustion engine starts when accelerating
or when the high voltage battery charge level
drops below a certain threshold. The vehicle re­
sumes electric driving once the acceleration and
the high voltage battery charge leve l permit .
Enhanced electric driving mode (EV mode)
Pressing the
i"*'I button ¢ fig. 111 can extend the
usual limits on e lectric driving so that you can a l­
ways dr ive in electric mode, if the condition of
the electrical system permits. The operating mode is then set to maximum electr ic drive @,
@ ¢page 98, fig. 110. It can be driven com­
pletely electrically for up to 1.8 miles (3 km) at a
constant
37 mph (60 km/h).
The following conditions must be met to activate
the enhanced electric drive:
- The high voltage battery must be sufficiently
charged.
- Th e temperature of the
12 volt batteries and
the high voltage battery must be sufficient.
- The vehicle speed must not be higher than
62 mph (100 km/h).
- The transmission must not be in tiptronic
mode .
- Offroad mode and hi ll descent assist must not
be turned on
r::!> page 191.
The combustion engine turns on and interrupts
the enhanced elect ric drive mode when the vehi­
cle is acce lerated. The gray indicator light
II al­
so turns on in the disp lay. The enhanced electric
drive mode resumes automatically once acce lera­
tion stops.
The enhanced electric drive mode is deactivated
if at least one of the following conditions is met:
- Th e ig nition is turned off.
- T he
l~ ·I button is pressed again .
- The high voltage battery charge level is low .
- The vehicle speed is higher than approximately
62 mph (100 km/h).
- The
S selector lever position or tiptronic mode
is selected.
- Offroad mode or hill descent assist is switched
on.
The
i oa!• I button must be pressed to reactivate it. ..,.
