Automatic transmission
1.Depress the brake.
2.Start the engine.
Special starting conditions
In the following situations, press the accelerator
pedal halfway down when starting the engine:
>If the engine does not start on the first
attempt, for instance when it is extremely
hot or cold.
>If the engine is started at very low tempera-
tures, below approx. +57/–156, at high
altitudes above approx. 3,300 ft/1,000 m.
Avoid frequent starting attempts in quick
succession or repeated starting attempts
during which the engine does not start. Other-
wise, the fuel is not burned or inadequately
burned; there is a danger of overheating and
damaging the catalytic converter.<
Switching off the engine
Do not remove the key while the vehicle is
still moving. Otherwise, the steering lock
would engage when the steering wheel is
turned.
When you leave the vehicle, always remove the
key and engage the steering lock.
Apply the parking brake when parking on steep
gradients, otherwise the vehicle could start to
roll.<
You can have an acoustic signal set as a
reminder that the key is still in the ignition
switch after the driver's door has been
opened.<
Manual transmission
1.Turn the key to position 1 or 0.
2.Engage first gear or reverse gear.
3.Apply the handbrake.
Automatic transmission
1.With the car at a standstill, move the selec-
tor lever to position P.
2.Turn the key to position 1 or 0.
Parking brake
The parking brake is designed primarily to pre-
vent the vehicle from rolling when parked. It
operates against the rear wheels.
Indicator lamp
The indicator lamp is lit, and when you
drive off a signal sounds in addition.
The handbrake is still applied.
Indicator lamp for Canadian models.
Applying
The lever locks in position automatically.
Releasing
Pull slightly upwards, press the button and
lower the lever.
If, in exceptional circumstances, it should
be necessary to engage the parking brake
while the vehicle is in motion, do not pull it with
excessive pressure. In doing so, continuously
press the button of the handbrake lever. Other-
wise, too violent an application of the hand-
brake can overbrake the rear axle and cause the
rear of the car to swerve.<
To prevent corrosion and one-sided brak-
ing action, occasionally apply the hand-
brake lightly when the vehicle is slowly coming
to a stop if the traffic conditions are suitable.
The brake lamps do not light up when the hand-
brake is applied.<

Rotary dial 5 is used to set the wipe interval to
one of four levels.
In addition, the wipe interval is varied automati-
cally depending on road speed.
Rain sensor*
On vehicles with a rain sensor, the wipe interval
is automatically controlled according to rain
intensity. The sensor is mounted on the wind-
shield, directly in front of the interior rearview
mirror.
Deactivate the rain sensor before enter-
ing an automatic car wash. Failure to do
so could result in damage caused by undesired
wiper activation.<
Activating
With the ignition key in position 1 or higher,
move the lever to position 1.
In any case, the wipers will move once across
the windshield.
You can leave the lever continuously in
position1. Then, as long as the ignition key is in position 1 or higher, you only need to activate
the rain sensor.
To do so:
>Turn rotary dial 5 briefly or
>Clean the windshield, refer to Cleaning
windshield and headlamps* below
Adjusting sensitivity
Turn the rotary wheel 5.
Deactivating
Flip the lever to position 0.

*
Do not use the washers if there is any
danger that the fluid will freeze on the
windshield, otherwise vision could be
obscured. Antifreeze should therefore be
added to the fluid, refer to Washer fluid on
page44.
Do not operate washing mechanisms when the
washer fluid reservoir is empty, otherwise you
will damage the washer pump.<

Cleaning windshield
The system sprays washer fluid against the
windshield and activates the wipers for a brief
period.
The windshield washer nozzles are automati-
cally heated
* when the engine is running or the
ignition is on.
Cleaning headlamps*
When the vehicle lighting system is switched
on, the headlamps are cleaned at regular and
appropriate intervals.
Washer fluid
Washer fluid antifreeze is flammable. For
this reason, keep it away from sources of
flame and store it only in its original container.
Store it so that it is inaccessible to children.
Comply with the instructions on the con-
tainer.<
Washer fluid reservoir
Fill with water and, if required, with antifreeze
according to its manufacturer's recommenda-
tions.
Mix the water and antifreeze before filling
the washer fluid reservoir to make sure
the correct concentration is maintained.<
Capacity
Approx. 5.3 US quarts/5 liters.
Cruise control*
The concept
Cruise control is available at speeds of at least
approx. 20 mph/30 km/h. The car stores and
maintains the speed that you specify with the
lever on the steering column.
Do not use cruise control if conditions are
unfavorable for driving at a constant
speed, e.g. due to winding roads, dense traffic,
or poor road conditions such as snow, rain, ice,
loose surface, etc. Otherwise, you could lose
control of the vehicle and cause an accident.<

To maintain current speed
Tap the lever, arrow 1, or pull it briefly, arrow 2.
The car's current speed is stored and main-
tained.
If, on downhill grades, the engine braking effect
is not sufficient, the controlled speed can be
exceeded. Speed can drop on uphill grades if
the engine output is insufficient.
To increase speed
Tap the lever repeatedly, arrow 1, until the
desired speed is reached.
Every time you tap the lever, the speed
increases by approx. 1 mph/1 km/h.

Parking lamps
In switch position1, the front, rear and side
vehicle lighting is switched on. You can use the
parking lamps to signal the position of the vehi-
cle when it is parked. For the additional option
of roadside parking lamps on one side of the
vehicle only, refer to page56.
The parking lamps will discharge the bat-
tery. Therefore, do not leave them on for
unduly long periods of time, otherwise the bat-
tery might not have enough power to start the
engine.<
Low beams
The low beams light up when the light switch is
in position 2 and the ignition is on.
When you switch off the ignition with the low
beam headlamps on, only the parking lamps will
remain on.
Defective bulb
The indicator lamp lights up:
At least one bulb of the vehicle's exte-
rior lighting has failed.
For replacing bulbs refer to page93.
Automatic headlamp control*
When the switch is in position3, the low beams
are switched on and off automatically depend-
ing on ambient light conditions, e.g. in a tunnel,
in twilight, or if there is precipitation.
When driving into tunnels with bright overhead
lights, there may be a delay before the head-
lamps come on.
The headlamps may also come on when the
sun is sitting low on a blue sky.
The low beams remain switched on inde-
pendent of the ambient lighting condi-
tions when you switch on the fog lamps
*.
When daytime running light is activated, refer to
page55, the low-beam headlamps are always
switched on when the switch is in position 3 and
the ignition is on.<
If desired, the light switch can remain in
position3. The exterior lamps are automatically
switched off after the vehicle is parked.
The automatic headlamp control cannot
serve as a substitute for your personal
judgment in determining when the lamps
should be switched on in response to ambient
lighting conditions. For example, the system
cannot detect fog or hazy weather. To avoid
safety risks, you should always switch on the
lamps manually under these conditions.<
You can have the sensitivity of your vehi-
cle's automatic headlamp control
adjusted.<
Daytime running light*
If desired, the light switch can remain in the
automatic headlamp control position. The exte-
rior lamps are automatically switched off after
the vehicle is parked.
In the Parking lamps position, the parking lamps
come on after the ignition is switched off.
If necessary, switch on the parking lamps as
described in the section about parking lamps.
