Sport program and manual operation
Press the S/M/D button on the steering
wheel:
The sport program is activated, and S
appears in the program indicator of the Info
Display. This program is recommended for
a performance-oriented driving style.
Pressing the S/M/D button again switches
into the manual mode.
When the buttons on the back of the steer-
ing wheel are touched, the transmission
upshifts. When the buttons on the front of
the steering wheel are touched, the trans-
mission downshifts. The Info Display shows
the manual ranges M1 through M6.
Upshifts and downshifts are executed only
when they will result in a plausible combi-
nation of engine and vehicle speed; thus,
for example, a downshift that would cause
the engine to overrev will not be executed
by the system. The selected gear appears
briefly in the Info Display, followed by the
current gear.
Pressing the S/M/D button again switches
into the Automatic program again, and D
appears in the program indicator of the Info
Display.
Malfunction
A message appears in the Check Control
and in the Control Display. The directional
arrows also start to flash in the Info Display.
A malfunction has occurred in the transmis-
sion system. Avoid heavy loads.
While it will remain still possible to move
the selector lever to any desired position,
the transmission will revert to operation in
its default mode with only a limited number
of forward gears.
Have the system checked as soon as pos-
sible.
Jump-starting and towing, refer to
pages209 and210.
Manual release of transmission
lockout
You can respond to any interruptions in the
supply of electrical power, for instance, if
the battery is discharged or disconnected,
by releasing the transmission lockout man-
ually.
To prevent the drive wheels from
locking up and sliding, the transmis-
sion lockout must always be released man-
ually before the vehicle is towed.<
Press the brake pedal before releas-
ing the transmission lockout manu-
ally. If the brakes are not applied, the vehi-
cle could start to roll if parked on a steep
slope.
The transmission lockout should only be
released for towing. Remember to engage
the transmission lockout when you repark
the vehicle after moving it.
Should it also be necessary to release the
parking brake manually, owing to a dis-
charged battery, etc., always adhere to the
following sequence:
1.Start by manually releasing the parking
brake, refer to page66
2.Then proceed to manually release the
transmission lockout.<
Jump-starting and towing, refer to
pages209 and210.

tion.<
Selecting wiper fold-out position
Important for changing wiper blades, when
folding away from windshield to prevent
blades from sticking when ice forms, etc.
1.Switch off the engine and remove the
remote control from the ignition lock
2.Press the wiper lever up and maintain
pressure for about 3 seconds until the
wipers are roughly vertical: this is the
fold-out position.
After folding the wipers back against the
windshield you will need to reactivate the
wiper system:
1.Insert the remote control to activate the
radio mode in the ignition lock
2.Apply brief upward pressure to the
wiper lever. The wipers return to their
retracted position and are ready for nor-
mal operation.
To prevent damage to the wipers,
always fold them back against the
windshield before switching on either the
radio mode or the ignition.<
Washer fluid
Washer fluid antifreeze is flammable.
Always keep it well away from sparks
and open flames, and store it in tightly
closed containers well out of the reach of
children. Always observe the instructions
for use provided on the containers.<
We recommend that you mix the
washer fluid before adding it to the
reservoir.<

Capacity: 6.3USquarts/6liters.
Fill with water and – if required – with a
washer antifreeze, according to manufac-
turer's recommendations.
Programmable cruise
control
The concept
The programmable cruise control is avail-
able for use at speeds of approx. 20 mph/
30 km/h and higher. The vehicle maintains
and stores the speed that you set using the
lever mounted on the steering column.
You can also use the multilevel preset
mode to store 6 desired speeds for later
selection with the same lever, refer to
page74.
This feature assists you in quickly adapting
the vehicle speed to specific road condi-
tions, e.g. changes in speeds limits.
Do not use the programmable cruise
control when driving on winding
roads, in heavy traffic or in poor road con-
ditions, e.g. snow, rain, ice, loose road sur-
face, that do not permit a constant speed.<

One lever for all functions
1 Maintaining and storing speed,
accelerating
Press the lever up to the resistance point:
The system maintains and stores the cur-
rent vehicle speed. Every time you briefly
press the lever, the vehicle's speed
increases by roughly 1 mph/1 km/h.
Press the lever longer:
The vehicle accelerates without pressure
on the accelerator pedal. The system main-
tains and stores your current speed as
soon as you release the lever.
The vehicle may accelerate beyond
the preset speed on steep downhill
stretches where the engine's braking effect
alone may not be sufficient to slow the
vehicle. Speed can drop on uphill grades if
the engine output is insufficient.<

This distance is always set
when the system is used for the
first time after starting the
engine.
Use good judgment to select the
appropriate following distance given
road conditions, traffic, applicable laws and
driving recommendations for safe following
distance.<
Things to know about active cruise control
As with conventional cruise control
systems, active cruise control in no
way diminishes or substitutes for the
driver's own personal responsibility, alert-
ness and awareness in adjusting speed,
braking or otherwise controlling the vehi-cle. The driver should decide when to use
the system on the basis of road, traffic, vis-
ibility, and weather conditions. Active
cruise control is intended for use on high-
way-type roadways where traffic is moving
relatively smoothly. Do not use this system

in city driving; heavy traffic such as during
rush hour; on curvy, winding roads, slip-
pery roads or roads with sharp curves such
as highway off-ramps; during inclement
weather such as snow, strong rain or fog;
or when entering interchanges, service/
parking areas or toll booths. It is also
important to regulate your vehicle's speed
and distance setting within applicable legal
limits. Always be ready to take action or
apply the brakes if necessary, especially
when the system is actively following a
vehicle in front of you.<
Always remember that the range and
ability of the system does have physi-
cal limitations. It will not apply the brakes or
decelerate your vehicle when there is a
slow-moving vehicle, stopped vehicle or
stationary object ahead of you, as for
example, at a traffic light or a parked vehi-
cle. Also, the system does not react to
oncoming traffic, pedestrians or other type
of potential traffic such as a rider on horse-
back. It is also possible that the system
may not detect smaller moving objects
such as motorcycles or bicycles. Be espe-
cially alert when encountering any of these
situations as the system will neither auto-
matically brake, nor provide a warning to
you. Also, be aware that every decrease in
the distance setting allows your vehicle to
come closer to a vehicle in front of you and
requires a heightened amount of alert-
ness.<
If while your vehicle is actively following a
vehicle in front of you and the vehicle
ahead speeds up or the lane ahead
becomes clear, then your vehicle will
accelerate to the speed you have selected.
Be aware that changing to a clear, unob-
st r uc ted lan e w il l als o r esu lt in y ou r v eh icle
accelerating.
Be certain to deactivate the system
when you pull into an exit lane for a
highway off-ramp.<
Also, vehicles traveling in a staggered man-
ner on a highway may cause a delay in the
system's reaction to a vehicle in front of you
or may cause the system to react to a vehi-
cle actually in the lane next to you. Always be ready to take action or apply the brakes
if necessary.
Active cruise control can only decelerate
the vehicle to approx. 20 mph/30 km/h. If
the system reduces vehicle speed below
20 mph/30 km/h or if DSC/ABS is engaged
while driving, the system will automatically
deactivate.
Remember, the system cannot stop
your vehicle. In addition, the system is
deactivated whenever the driver applies
the vehicle brakes, shifts the transmission
from drive/D to neutral/N, or deactivates
DSC. After any deactivation, the system will
no longer automatically activate the vehicle
brakes, which means the driver must inter-
vene and resume manual braking. You
should then reactivate the system only
when you are fully aware of the prior speed
and distance settings.<
Active cruise control may brake when you
reduce the stored desired speed; however,
the driver must constantly monitor traffic
and intervene if necessary.
When you switch off the engine or ignition,
active cruise control is fully switched off,
too, and any settings you have selected are
canceled.
Behavior in curves
Because of the limited range of the system,
it is possible that in curves or on the peaks
and valleys of hilly roads, a vehicle ahead
may be recognized late, or not at all. There-
fore, it is up to the driver to select a speed
that is prudent in view of the curves and
terrain of the roadway.

"Fuel reserve" appear. The tank still con-
tains approx. 2.6 gallons/10 liters of fuel.
If the tilt of the vehicle varies, when you are
driving in mountainous areas, for example,
the indicator may fluctuate slightly.
It will not be possible to cancel the
computer display once the fuel level
drops into the reserve range. However, you
can still request a display of the travel
range. Computer, refer to page85.<
Fuel tank capacity: approx. 23.2 gallons/
88 liters. You can find information on refu-
eling on page186.
Refuel well before the tank is empty,
as otherwise engine functions will not
be ensured and damage can occur if you
drive down to the last drop.<
Cruising range
Displays the estimated cruising range avail-
able with the remaining fuel. The fuel level
is measured and the range is calculated
taking the driving style over the last
20 miles/30 km into account.
Always refuel as soon as possible
once your range falls to below
30 miles/50 km, as otherwise engine func-tions are not ensured and damage can
occur.<
Refueling is only registered by the com-
puter for fuel amounts above approx.
1.3 gallons/5 liters.
Remaining distance
When you enter a destination in the naviga-
tion system or manually enter a distance in
the computer prior to departure, the system
can also display the distance remaining to
your destination, refer to page132 or87.
The system automatically applies the dis-
tance to your destination using the route
recommended by the navigation system.

EBV Electronic brake-force
distribution
EBV controls the brake system's applica-
tion pressure at the rear wheels to ensure
stable deceleration.
DSC Dynamic Stability Control
The system optimizes vehicle stability dur-
ing acceleration and when starting from a
full stop, as well as optimizing traction.
The system recognizes any tendency for
the vehicle to assume an unstable attitude
such as oversteer or understeer; it then
counteracts this tendency with a combina-
tion of graduated reductions in engine
torque and selective braking intervention at
individual wheels. DSC provides optimized
stability within the limits defined by the
laws of physics.
The DSC is operational every time you start
the engine. DSC contains the functions
DTC Dynamic Traction Control and DBC
Dynamic Brake Control.
Indicator lamp
The indicator lamp goes out shortly
after the engine starts.
The indicator lamp flashes:
DSC controls the drive and braking forces.
The indicator lamp stays lit:
DSC has been switched off using the Con-
trol Center.
Activating DTC Dynamic Traction
Control
In particular driving situations, in deep
snow, for example, DTC ensures the maxi-
mum forward momentum. The gain in for-
ward momentum in these situations
involves a reduction in vehicle stability.
DTC is active up to 45 mph/70 km/h.You may find it useful to briefly activate
DTC under the following special circum-
stances:
>When rocking the vehicle and starting
off in deep snow or on loose road sur-
faces
>When ascending snow-covered hills,
and when driving in deep or on hard-
packed snow
>When driving with snow chains.
Select "Settings". Select "DTC" and con-
firm your selection. DTC is now activated.
The DTC indicator lamp in the Info Display
lights up permanently.
When DTC is active, DSC provides
only limited system response up to a
speed of approximately 45 mph/70 km/h.
Intervention for stability enhancement is
reduced.<
Deactivating DTC again
Select "Settings". Select "DTC" and con-
firm your selection. DTC is now deacti-
vated. The DTC indicator lamp in the Info
Display goes out. DSC is once again avail-
able without restriction.
