Controls
Ignition on
All electrical consumers can operate. The
odometer and trip odometer are displayed in
the instrument cluster.
When the engine is off, please switch
off the ignition and any unnecessary
electrical consumers in order to preserve the
battery. <
Radio readiness and ignition off
All indicator and warning lamps as well as
displays in the instrument cluster go out.
Starting the engine
Do not run the engine in enclosed areas;
otherwise, the inhalation of toxic exhaust
gases can cause loss of consciousness and
death. The exhaust gases contain carbon mon-
oxide, an odorless and colorless, but highly
toxic gas. Never leave an unattended vehicle
with the engine running; otherwise, such a
vehicle represents a po tential safety hazard.
Before leaving the car with the engine running,
place the transmission in neutral or move the
selector lever to positi on P and forcefully apply
the parking brake to prevent the car from
moving. <
Avoid frequent starting in quick succes-
sion as well as repeat ed start attempts in
which the engine does not start. Otherwise, the
fuel is not burned or incompletely burned and
there is a danger of overheating and damaging
the catalytic converter. <
Do not wait for the engine to warm up while the
vehicle remains stationary. Start driving right
away, but at moderate engine speeds.
Manual transmission
Remote control in the ignition lock or, with
Comfort Access, inside the vehicle, refer to
page 40.
1. Depress the brake.
2. Depress the clutch and shift into neutral.
3. Press the Start/Stop button.
The starter operates automatically for a certain
time, and stops automati cally as soon as the
engine has started.
Automatic transmission
Remote control in the ignition lock or, with
Comfort Access, inside the vehicle, refer to
page 40.
1. Depress the brake.
2. Move the selector lever to position P.
3. Press the Start/Stop button.
The starter operates automatically for a certain
time, and stops automati cally as soon as the
engine has started.
Sport automatic transmission with
double clutch
Remote control in the ignition lock or, with
Comfort Access, inside the vehicle, refer to
page 40.
1. Depress the brake.
2. Press the Start/Stop button.
The engine starts independent of the current
transmission position.

System limitations
The 7-gear Sport automa tic transmission with
double clutch has an overheating protection
that protects the clutch from extreme loads.
The indicator lamp lights up in yellow if
the transmission becomes too warm.
Avoid high engine loads and frequent
accelerations from zero. If the transmission is
overheated, the indicator lamp lights up in red
and the power flow to the motor is interrupted. It
is only possible to continue driving once the
transmission has cooled down.
Avoid frequent powerful accelerations from
zero and do not hold the vehicle on inclines by
pressing lightly on the accelerator while letting
the clutch slip, as this may cause the transmis-
sion to overheat.
Selector lever positions
P R N D M/S + –
Displays in the instrument cluster
The selector lever posi tion and the engaged
gear are displayed, e.g. M4.
Engaging selector lever positions
> The selector lever can be moved out of
position P only with the engine running:
interlock.
> Before moving the lever away from P or N
with the vehicle stationary, first depress the
brake; otherwise, the desired shift will not
be executed: shiftlock.
Shifting into N, D, R
Briefly push the selector lever in the desired
direction, overcoming a resistance point if
necessary. When shifting out of P or into R,
simultaneously press the button 1.
The engaged selector le ver position is also
displayed on the selector lever.
When you release the sele ctor lever, it returns
to its center position.
Shifting into P
Press the button P.
P Park
Select this only when th e vehicle is stationary.
The rear wheels are locked.
The transmission is shifted into P if, with
the engine running, you open the driver's
door, do not have your safety belt fastened, and
subsequently actuate neither the brake pedal
nor the accelerator. Befo re leaving the vehicle,
make sure that the automatic transmission
selector lever is in the park position. Otherwise,
the vehicle may begin to move. <

Things to remember when driving
Driving tips
Hills
To prevent overheating and the resulting
reduced efficiency of the brake system,
drive long or steep downhill gradients in the
gear in which the least br aking is required. Even
light but consistent brak e pressure can lead to
high temperatures, brake wear and possibly
even brake failure. <
You can increase the engine's braking effect by
shifting down, all the way to first gear if neces-
sary. This strategy he lps you avoid placing
excessive loads on the brake system. Down-
shifting in manual mo de of the automatic
transmission, refer to page 66.
Sport automatic transm ission with double
clutch: never drive with the transmission
in neutral or with the en gine switched off; other-
wise, there will be no en gine braking action and
no power assistance to the brakes and steering.
Manual transmission: never drive with the
clutch held down, with the transmission in neu-
tral or with the engine switched off; otherwise,
there will be no engine braking action and no
power assistance to the brakes and steering. <
Corrosion on brake rotors
When the vehicle is driven only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications are le ss frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminan ts accumulate on the
brake pads. This occurs because the minimum
pressure which must be exerted by the pads
during brake applications to clean the rotors is
not reached.
Should corrosion form on the brake rotors, the
brakes will tend to respond with a pulsating
effect that even extended application will fail to
cure.
When the vehicle is parked
Condensation forms while the automatic
climate control is in operation, and then exits
under the vehicle. Traces of condensed water
under the vehicle are therefore normal.
Cargo loading
To avoid loading the tires beyond their
approved carrying ca pacity, never over-
load the vehicle. Overlo ading can lead to over-
heating and increases the rate at which damage
develops inside the tires. In some situations,
this can result in sudden loss of tire pressure. <
Make sure that no liquids are spilled or
leak from their containers in the trunk, as
this could result in damage to the vehicle.<
Determining loading limit
1. Locate the following statement on your
vehicle's placard:
The combined weight of occupants
and cargo should never exceed
XXX kg or YYY lbs. Otherwise damage to
the vehicle may occur and unstable driving
conditions may result.<
2. Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.
3. Subtract the combined weight of the driver
and passengers from XXX kilograms or YYY
pounds.
4. The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the YYY amount equals
