Selector lever positions
BPark position
This prevents the vehicle from rolling
away when stopped. Only move the
selector lever toPif the vehicle is
stationary.
You can only remove the key when
the selector lever is in this position.
The selector lever is locked in posi-
tion Pif the key is removed.
The parking lock should not be used
as a brake when parking. Always
apply the parking brake as well once
you have parked the vehicle.
CReverse gear
Only move the selector lever to R
when the vehicle is stationary.
ANeutral
No power is transmitted from the
engine to the drive wheels. Releasing
the brakes will allow you to move the
vehicle freely, e.g. by pushing.
Do not move the selector lever to N
while driving. The automatic trans-
mission could otherwise be dam-
aged.
If ASR is deactivated or ESP
®has
malfunctioned: only move the selec-
tor lever to Nif the vehicle is in dan-
ger of skidding, e.g. on icy roads.
7Drive
The automatic transmission changes
gear itself. All forward gears are avail-
able.
You can influence the gearshifts and
shift gears yourself or limit the shift
range.
Changing gear
The 5-speed automatic transmission adapts to
your individual driving style by continuously
adjusting its shift points. These shift point
adjustments take into account the current oper-
ating and driving conditions. If the operating or
driving conditions change, the automatic trans-
mission reacts by adjusting the gearshift pro-
gram.
When the selector lever is in position D, the
automatic transmission selects the individual
gears automatically. This depends on:
Rany restriction in the shift range
(Ypage 123)
Rthe position of the accelerator pedal
Rthe road speed
Touchshift
When the selector lever is in position D, you can
perform gearshifts yourself.
XTo shift down: press the selector lever to the
left towards D–.
The automatic transmission shifts to the next gear down, depending on the gear currently
engaged. The shift range is also restricted.
iThe automatic transmission does not shift
down if you press the selector lever towards
D– while traveling at too high a speed. This
protects the engine from overrevving.
XTo shift up: briefly press the selector lever to
the right towards D+.
The automatic transmission shifts to the next
gear up, depending on the current gearshift
program. This also extends the shift range.
XTo derestrict the shift range: press and hold
the selector lever towards D+until D
appears
in the display again.
The automatic transmission shifts from the
current shift range directly to D.
XTo select the optimum shift range: press
and hold the selector lever to the left towards
D–.
The automatic transmission will shift to a
range which allows easy acceleration and
deceleration. To do this, the automatic trans-
mission will shift down one or more gears.

Shift ranges
When the selector lever is in positionDyou can
restrict or derestrict the shift range for the auto- matic transmission.
XTo extend and restrict the shift range:
press the selector lever briefly to the right
towards D+or left towards D–.
The display shows the selected shift range.
The automatic transmission shifts only as far
as the relevant gear.
iIf the maximum engine speed for the restric-
ted shift range is reached and you depress the
accelerator pedal, the automatic transmis-
sion will not shift up.
Driving situations
5Use the braking effect of the engine
on steep downhill gradients and for
driving:
Ron steep mountain roads
Rin mountainous terrain
Rin arduous conditions
4Use the braking effect of the engine
on extremely steep downhill gradi-
ents and long downhill stretches.
Driving tips
Accelerator pedal position
Your style of driving influences how the auto-
matic transmission shifts gear:
Rlittle throttle: early upshifts
Rlots of throttle: later upshifts
Kickdown
Use kickdown for maximum acceleration:
XDepress the accelerator pedal beyond the
pressure point.
The automatic transmission shifts to the next
gear down, depending on the engine speed.
XEase off on the accelerator pedal once the
desired speed is reached.
The automatic transmission shifts up again.
Maneuvering
Maneuvering in a tight space:
XControl the vehicle's speed by braking care-
fully.
XDepress the accelerator pedal slightly and
evenly.
iYou can shift back and forth between drive
position Dand reverse gear Rat low speeds
without applying the brakes. This can help
you, for example when rapidly maneuvering
the vehicle or rocking it out of snow or slush.
Towing a trailer
XDrive at moderate engine speeds on steep
uphill gradients.
XDepending on the uphill or downhill gradient,
shift down to a shift range adapted to the
driving situation (

Important safety notes
GWARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with
hot parts of the exhaust system or exhaust
gas flow. There is a risk of fire.
Park the vehicle so that no flammable mate-
rials come into contact with parts of the vehi-
cle which are hot. Take particular care not to
park on dry grassland or harvested grain
fields.
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
GWARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example:
Rrelease the parking brake.
Rshift the automatic transmission out of the
parking position P.
Rstart the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
!A moving vehicle can lead to damage to the
vehicle or damage to the drive train.
!When the vehicle is parked, always remove
the key to prevent the battery from becoming
discharged.
On vehicles with a battery isolating switch,
switch off the power supply if the vehicle is to
be out of use for a longer period of time.

Always park your vehicle safely and according to
legal requirements and secure it against rolling
away.
To ensure that the vehicle is properly secured
against rolling away unintentionally:
Rthe parking brake must be firmly applied
Rthe selector lever must be in positionPand
the key must be removed from the ignition
lock
Ron steep uphill or downhill gradients, the front
wheels must be turned towards the curb
Rthe rear axle must be secured, e.g. with a
wheel chock, on steep uphill or downhill gra-
dients
Use the wheel chock (
Ypage 129) to do so.
If you leave the vehicle parked for more than
three weeks:
Rconnect the batteries to a trickle charger or
Rdisconnect the vehicle's starter battery or
Rswitch off the electrical system using the bat-
tery main switch (Ypage 116) and
Rdisconnect the vehicle's auxiliary battery
Otherwise, you need to check the battery's con-
dition of charge every three weeks, since
standby power consumption can drain the bat-
tery. If the battery voltage is lower than 12.2 V,
the battery must be charged. Otherwise, the
battery may be damaged by exhaustive dis-
charging.
Be sure to observe the notes on disconnecting
and chargi ng th
e batteries under "Bat-
tery“ (Ypage 223). You can obtain information
about trickle chargers from a qualified specialist

There is a risk of an accident.
Alwa ys pay careful attention to the traff icsit-
uation and donot rely solely on the distance
warning function.
Operation
The distance warning function can help you to
minimize the risk of a front-end collision with a
vehicle ahead or reduce the effects of such a
collision. Ifthe distance warning function
detects that there isa risk of a collision, you will
be warned visually and acoustically. Without
your intervention, the distance warning function
cannot prevent a collision.
The distance warning function willissue a warn-
ing at speeds of around 20 mph (30 km/h)or
more if:
Ryou approach a vehicle ahead of you very
quickly. You will then hear an intermittent
warning tone and the red ·warning lamp
