WARNING
● When the engine is running, the vehicle will start to move as soon as
a gear is engaged and the clutch released.
● Never select the reverse gear when the vehicle is in motion. Risk of
accident.
Note
● Do not rest your hand on the gear lever while driving. The pressure of
your hand could cause premature wear on the selector forks in the gearbox.
● When changing gear, you should always depress the clutch fully to
avoid unnecessary wear and damage.
● Do not hold the vehicle “on the clutch” on hills. This causes premature
wear and damage to the clutch.
● Do not leave your foot on the clutch pedal; although the pressure may
seem insignificant, it can cause the premature wear of the clutch plate. Use
the foot rest when you do not need to change gear. 
Automatic gearbox* Introduction
multitronic ®
, tiptronic (7-speed gearbox)
Vehicles with multitronic ®
gearbox
The vehicle is equipped with an electronically controlled continuously varia-
ble transmission (multitronic ®
). Unlike conventional automatics, the gear
ratios are not shifted in fixed steps but continuously variable. This gives
smoother transmission and makes for better fuel economy. The gearbox selects the gear ratio and shifts up or down automatically ac-
cording to the gear change programmes stored in the control unit
⇒ page 192.
If desired, you can also select the gears
manually (tiptronic mode)
⇒ page 193.
Please note that in vehicles with a multitronic® gearbox, torque is transmit-
ted via a multi-plate clutch, and not via a torque converter as on convention-
al automatics. This means that the vehicle will not “creep” as much as con-
ventional automatics when the engine is idling if you stop temporarily with
the selector lever in position D, S or R.
Vehicles with tiptronic gearbox
The vehicle is equipped with an electronically controlled 7-speed automatic
gearbox. The gearbox changes up and down automatically.
If desired, you can also select the gears manually (tiptronic mode)

lector lever with lock but-
ton
Starting the vehicle
– Press and hold the brake pedal.
– Press and hold the interlock button (the button on the selector
lever handle), move the selector lever to the required position,
for instance D, and release the interlock button.
– Wait for the gearbox to engage the gear (a slight movement can
be felt).
– Release the brake and press the accelerator ⇒ 
.
Stopping briefly
– Apply the foot brake to hold the vehicle when stationary (for in-
stance at traffic lights). –
To prevent the vehicle from rolling away, apply the parking
brake before moving off on steep gradients ⇒ 
.
Parking
– Press and hold the brake pedal ⇒ 
.
– Apply the parking brake.
– Press and hold the interlock button, move the selector lever to P
and release the interlock button.
The engine can only be started when the selector lever is at P or N.
On level ground it is sufficient to move the selector lever to position P. On
slopes, first engage the parking brake and then put the selection lever into
the P position. This avoids overloading the locking mechanism and it will be
easier to move the selector lever from position P.
Vehicles with multitronic® gearbox: Your vehicle is equipped with the hill
hold assist function which makes it easier to start off on a slope. The sys-
tem is activated when you press and hold the brake pedal for a few sec-
onds. When you release the brake pedal the braking force will be main-
tained for a short moment in order to prevent the vehicle rolling back when
you drive away.
WARNING
● While you are selecting a gear and the vehicle is stopped with the en-
gine running, do not accelerate. Failure to do so could result in an acci-
dent.
● Please note that some power will still be transmitted when you stop
temporarily with the selector lever in position D, S or R. Therefore, when
stopping you will need to press the brake with the force required to hold
the vehicle still. Failure to do so could result in an accident.
● Never move the selector lever to R or P when driving, as this could
cause an accident.

Selector lever positions
This section covers all the selector lever positions.
Fig. 159 Display: Selec-
tor lever positions
The current selector lever position is shown on the instrument panel dis-
play.
P - parking lock
This locks the driving wheels mechanically. The parking brake should only
be used when the vehicle is already stopped
⇒ 
.
The interlock button (the button on the selector lever handle) must be
pressed in and the brake pedal must be depressed before moving the selec-
tor lever either in or out of position P. This is only possible when the ignition
is on.
R - Reverse gear
When reverse gear is engaged the gearbox automatically selects the lowest
gear ratio.
The reverse gear may be engaged only when the vehicle is stationary and
the engine is idling ⇒ 
. To move the selector lever to position R, press in the interlock button
and at
the same time press the brake pedal. Depending on the model, one or two
reverse lights will come on in selector lever position R (when ignition is
switched on).
N - Neutral (idling)
In this position the gearbox is in neutral ⇒ 
.
D - Drive (forward)
In this position, the gearbox selects the optimal transmission ratio depend-
ing on the engine load, speed and the dynamic gear regulation programme
(DRP).
Press the brake pedal when moving the selector lever from N to D if the ve-
hicle is stationary or at speeds below 5 km/h ⇒ 
.
Under certain circumstances (e.g. when driving in mountains or towing a
trailer or caravan) it can be advantageous to switch temporarily to tiptronic
mode ⇒ page 193, so that the gear ratios can be selected manually to suit
the driving conditions.
S - Sport position
To drive in sports mode, select the position S. The engine power reserve is
used to its maximum. When accelerating the gear shifts will be noticeable.
Press the brake pedal when moving the selector lever from N to S if the vehi-
cle is stationary or at speeds below 5 km/h ⇒ 
.
WARNING
● Never move the selector lever to R or P when driving. Failure to do so
could result in an accident.
● In selector position D or S the vehicle must always be held with the
foot brake when the engine is running. This is because an automatic
gearbox still transmits power even at idling speed, and the vehicle tends 

Driving
WARNING (Continued)
to “creep”. The throttle must on no account be opened inadvertently (for
instance by hand from the engine compartment) when a gear is engaged
with the vehicle stationary. The vehicle could otherwise start moving im-
mediately (in some cases even if the parking brake is engaged) and pos-
sibly cause an accident.
● To avoid accidents, apply the parking brake and put the selector lever
in position P before opening the bonnet and working on the vehicle with
the engine running. Please always observe the important safety warn-
ings ⇒ page 235, Work in the engine compartment.
Note
● Applies to vehicles with tiptronic gearbox:
● If the lever is moved accidentally to N when driving, release the accelera-
tor and let the engine speed drop to idling before selecting D or S again.
● For the sake of fuel economy (and the environment), the gearbox ratios
on some models are designed so that maximum speed is only obtained
when the gear lever is in position S. Selector lever lock
The selector lever lock prevents gears from being engaged
inadvertently, so that the vehicle is not set in motion unin-
tentionally.
Fig. 160 Selector lever
lock
The selector lever lock is released as follows:
– Switch the ignition on.
– Press the brake pedal and at the same time press in the inter-
lock button.
Automatic selector lever lock
With the ignition turned on, the selector lever is locked in the positions P
and N. To remove it from these positions, press on the brake. The following
message appears in the instrument panel as a reminder for the driver when
the selector lever is in position P or N: WHEN STATIONARY APPLY FOOTBRAKE WHILE SELECTING GEAR 
Safety FirstOperating instructionsPractical TipsTechnical Specifications

192Driving
The selector lever lock only works if the vehicle is stationary or driving at
speeds up to 5 km/h (3 mph). At higher speeds the selector lever lock in
the N position is disengaged automatically.
The selector lever lock is not engaged if the selector lever is moved quickly
through position N (e.g. when shifting from R to D). This makes it possible,
for instance, to “rock” the vehicle backwards and forwards if it is stuck in
snow or mud. The selector lever lock engages automatically if the brake
pedal is not depressed and the lever is in position N for more than about a
second.
Interlock button
The interlock button on the selector lever handle prevents the driver from
inadvertently engaging certain gears. Press the button in to disengage the
selector lever lock. The selector lever positions in which the interlock button
has to be pressed are shown in the illustration, highlighted in colour
⇒  Fig. 160.
Safety interlock for ignition key
Once the ignition has been turned off, the key may be removed only if the
gear selector is in position P. While the key is not in the ignition, the selec-
tor lever is locked in position P. 
Kick-down feature
This feature allows maximum acceleration. Vehicles with multitronic ®
gearbox
When the accelerator pedal is pressed right down past the point of resist-
ance at full throttle, the gearbox will select a lower gear ratio, depending on
road speed and engine speed. While you keep the accelerator depressed
the engine speed is automatically controlled to give your vehicle maximum
acceleration. Vehicles with tiptronic gearbox
When the accelerator pedal is pressed right down past the point of resist-
ance at full throttle, the gearbox will shift down to a lower gear, depending
on road speed and engine speed. The upshift to the next higher gear is de-
layed until the engine reaches maximum rpm.
WARNING
Please note that if the road surface is slippery or wet, the kick-down fea-
ture could cause the driving wheels to spin, which could result in skid-
ding.

Dynamic gear control programme (DCP)
The automatic gearbox is controlled electronically.
The vehicle is equipped with an electronically controlled gearbox. The gear
ratios are selected automatically according to preset gearshift programmes.
When you drive at moderate speeds the gearbox will select the most eco-
nomical shift programme. It will then change up early and delay the down-
shifts to give better fuel economy.
If you drive at higher speeds with heavy acceleration, if you open the throt-
tle quickly, or if you use the kick-down or the vehicle's maximum speed, the
gearbox will automatically select the sport programme.
The gearbox is self-adapting, and continuously selects the most suitable
shift programme. At the same time, the driver can also make the gearbox
switch to the sport programme by pressing the accelerator quickly. This
makes the gearbox shift down into a lower gear ratio, allowing a more rapid
acceleration (for instance to pass another vehicle), without having to press
the accelerator all the way down into the kick-down position. After the gear-
box has shifted back up it returns to the original programme, depending on
your style of driving. 

193
Driving
Vehicles with multitronic® gearbox: the gearbox continuously adapts the
gear ratios to gradients. If the brake pedal is pressed on a downhill gradient
the gearbox automatically shifts to a lower gear ratio. This increases the en-
gine braking effect.
Vehicles with tiptronic gearbox: in mountainous areas, the gearbox adapts
the gears for uphill and downhill gradients. This helps to avoid constant
gear changes on uphill gradients. 
Manual gear selection (tiptronic mode)
With the manual shift programme (tiptronic) the driver can
manually select pre-programmed gears.

(tiptronic mode)
Fig. 162 Display: Man-
ual gear selection (tip-
tronic mode)
Switching over to the manual programme
– Move the selector lever from the position D to the right-hand
side. As soon as the selector lever has entered the tiptronic rail,
the gear engaged is displayed on the screen.
Shifting up a gear
– Briefly push the selector lever forwards (in the tiptronic gate)
⇒ Fig. 161 +
.
Shifting down a gear
– Briefly pull the selector lever backwards (in the tiptronic gate)
-
.
With the tiptronic system, the driver can manually choose between eight (in
vehicles with multitronic) or seven (in vehicles with tiptronic) different gear
programmes. The manual programme can be selected either with the vehi-
cle stationary or on the move.
When accelerating, the gearbox automatically shifts up into the next gear
shortly before the maximum engine speed is reached. 
Safety FirstOperating instructionsPractical TipsTechnical Specifications

194Driving
If you select a gear which is lower than the gear shown on the instrument
panel display ⇒ Fig. 162, the gearbox will only shift down when there is no
longer a risk of over-revving the engine.
When the vehicle slows down (for instance when braking), the gearbox au-
tomatically shifts down into the next gear when the minimum engine speed
is reached.
Changing down to a lower gear increases the engine braking effect on
downhill gradients.
When the accelerator pedal is pressed right down past the point of resist-
ance at full throttle, the gearbox will select a lower gear ratio, depending on
road speed and engine speed. 
Back-up programme
A backup programme is in place if a fault should occur in the
control system.
The automatic gearbox switches to the back-up programme if a fault should
occur in the control system. This is indicated by a gear pinion symbol which
lights up on the instrument panel display.
It is still possible to move the selector lever to all positions. The manual
shift programme (tiptronic) is not available when the back-up programme is
active.
Vehicles with tiptronic gearbox: When the selector lever is in position D or S
or in the manual shift programme, the gearbox will remain in 3rd gear if 1st,
2nd or 3rd gears were engaged when the fault occurred. The gearbox will
remain in 5th gear if 4th, 5th or 6th gears were engaged. The gearbox will
then engage 3rd gear when you drive away from a standstill or after the en-
gine is restarted. It will still be possible to use reverse gear in the normal way. However, the
electronic lock for reverse gear will be switched off.
CAUTION
Should the gearbox ever switch into the back-up programme, you should
take the vehicle to a technical service or specialised workshop as soon as
possible. 

Electronic Stability Control (ESC)
General Observations
The Electronic Stability Control increases the vehicle's stabil-
ity on the road.
Fig. 164 Centre console
with ESC switch
The ESC is designed to increase the degree of control in situations where
the vehicle approaches the limits of adhesion, especially when accelerating
and cornering. It reduces the risk of skidding and improves stability in all
road conditions. The system is active across the entire speed range. The anti-lock brake system (ABS), the electronic differential lock (EDL) and
the traction control system (ASR) are all integrated into the Electronic Stabil-
ity Control.
How it works
The ESC control unit processes data from the three integrated systems. It al-
so processes additional inputs provided by other high-precision sensors.
These register the vehicle's rotation about the vertical axis (yaw rate), later-
al acceleration, brake pressure and steering wheel angle.
The system uses the steering wheel angle and road speed to calculate the
changes of direction desired by the driver, and constantly compares them
with the actual behaviour of the vehicle. If the desired course is not being
maintained (for instance, if the vehicle is starting to skid), then the ESC
compensates automatically by braking the appropriate wheel.
The forces acting on the braked wheel bring the vehicle back to a stable
condition. If the vehicle
over swerves (tendency of the rear to leave the
road), the brakes will act on the front wheel facing the outside of the bend.
If the vehicle under swerves (tendency to leave the bend), the braking force
is applied to the rear wheel facing the inside of the bend.
The ESC works in conjunction with the ABS ⇒ page 197. If a malfunction
should occur in the ABS, the ESC will also stop working.
Deactivating
The ESC is activated automatically when the engine is started and performs
a self-test routine.
The ESC cannot be deactivated. 

199
Intelligent technology
The traction control system (ASR) helps the car to start moving, accelerate
and climb a gradient in slippery conditions where this may otherwise be dif-
ficult or even impossible.
How it works
The ASR works automatically, i.e. without the driver's involvement. With the
aid of the ABS sensors , the ASR monitors the speed of the driven wheels
⇒  page 197. If the wheels start to spin, the engine speed is reduced auto-
matically to match the amount of grip available. The system is active across
the entire speed range.
The ASR works in conjunction with the ABS. If a failure occurs in the ABS,
the ASR will also stop working.
In general, the ASR should be left switched on at all times. It should only be
switched off manually in particular circumstances where a certain amount of
wheel slip may be desirable. Examples:
● when driving with snow chains
● when driving in deep snow or on loose surfaces
● when rocking the vehicle backwards and forwards to free it.
The ASR should be switched on again afterwards as soon as possible.
Note
To ensure that the ASR works properly, all four wheels must be fitted with
identical tyres. The difference in size of the wheels may lead to an unde-
sired reduction in engine power. Also see ⇒  page 257.Brakes
General notes
New brake pads
New brake pads do not provide optimal performance during the first 200 km
(250 miles); first they must be “run in”. However, the reduced braking ca-
pacity may be compensated by pressing on the brake pedal a little harder.
Avoid overloading the brakes during run-in.
Wear
The rate of wear on the brake pads depends a great deal on how you drive
and the conditions in which the vehicle is operated. Negative factors are, for
instance, city traffic, frequent short trips or hard driving with abrupt starts
and stops.
Wet roads or road salt
In certain conditions, such as in heavy rain, or after washing the vehicle or
driving through water, the full braking effect can be delayed by moisture (or
in winter by ice) on the discs and brake pads. In this case the brakes should
be dried by pressing the brake pedal several times.
The effectiveness of the brakes can also be temporarily reduced if the vehi-
cle is driven for some distance without using the brakes when there is a lot
of salt on the road in winter. In this case, the layer of salt on the brake discs
and pads has to wear off before braking.
Corrosion
There may be a tendency for corrosion to form on the discs and dirt to build
up on the brake pads if the vehicle is used infrequently or the brakes are
not used very often.
If the brakes are not used frequently, or if rust has formed on the disks, it is
advisable to clean off the pads and disks by braking firmly a few times at a
moderately high speed ⇒
