ControlsDriving
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 electri-
cal consumers in order to preserve the bat-
tery.<
Radio readiness and ignition off
All indicator and warning lamps as well as dis-
plays in the instrument cluster go out.
Starting the engine
Do not run the engine in enclosed areas;
otherwise, the inhalati on 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 vehi-
cle represents a pote ntial safety hazard.
Before leaving the vehicl e with the engine run-
ning, always shift into ne utral or selector lever/
transmission position P and apply the parking
brake forcefully to prevent the vehicle from roll-
ing. <
Avoid frequent starting in quick succes-
sion as well as repeated start attempts in
which the engine does no t 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 38.
1. Depress the brake.
2. Depress the clutch an d shift into neutral.
3. Press the Start/Stop button.
The starter operates automatically for a certain
time, and stops automatically 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 38.
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 automatically 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 38.
1. Depress the brake.
2. Press the Start/Stop button.
The engine starts independent of the current
transmission position.

ControlsDriving
Upshifts and downshifts are executed only
when they will result in a plausible combination
of engine and vehicle speed; thus, for example,
a downshift that would cause the engine to
overrev will not be exec uted by the system.
The gear selected is briefly displayed in the
instrument cluster, followed again by the gear
actually in use.
Overriding selector lever lock
Should the selector lever refuse to move out of
position P even though the ignition is switched
on, the brake is depressed and the button on
the selector lever is pre ssed, the selector lever
lock can be overridden:
1. Switch off ignition.
2. Unclip the sleeve of the selector lever.
3. Pull the sleeve up over the selector lever
until the sleeve is inside out.
4. Using the screwdriver from the onboard
vehicle tool kit, refer to page 270, press the
red lever and with the button pressed,
simultaneously move th e selector lever to
the desired position.
7-gear Spor t automatic
transmission with double
clutch
The concept
The 7-gear Sport automa tic transmission with
double clutch is an automated manual trans-
mission with two clutches and secondary gear sets in which the clutch
ing and shifting is han-
dled by an electrohydraulic system.
With the 7-gear Sport automatic transmission
with double clutch, the gears are shifted without
an interruption in driving power.
You operate the 7-gear Sport automatic trans-
mission with double clutch using the selector
lever and two shift paddles on the steering
wheel.
It offers you the following functions:
> Either manual or au tomatic mode: sequen-
tial mode or drive mode
> Automatic downshifting and protection
against incorrect gear selection, even in
sequential mode
> Acceleration assistan t, Launch Control,
refer to page 70
> Automatic intermediate throttle application
System limitations
The 7-gear Sport automatic 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.

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 mode of the automatic trans-
mission, refer to page 65.
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.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
pedals; otherwise, pedal function could be
impaired. <
Corrosion on brake rotors
When the vehicle is driv en 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 wh ile the automatic cli-
mate 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 cargo
area, as this could result in damage to the vehi-
cle. <
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 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.
