to obtain additional support in the lumbar
region.
The upper hips and spinal column receive sup-
plementary support to help you maintain a
relaxed, upright sitting position.
>Increase or decrease curvature: press the
switch at the front or rear, respectively.>Shift curvature up or down: press the switch
at the top or bottom, respectively.
Backrest width*
You can change the width of the backrest to suit
your individual preferences by adjusting the lat-
eral-support pads.
Press the front or rear end of the switch.
Backrest width decreases or increases accord-
ingly.
Head restraints
Correctly adjusted head restraint
A correctly adjusted head restraint reduces the
risk of neck injury in the event of an accident.
Adjust the head restraint in such a way
that its center is at approx. ear level. Oth-
erwise, there is an increased risk of injury in the
event of an accident. Only remove a head
restraint if no one will be sitting on the seat in
question. Reinstall the head restraint before
transporting anyone on that seat. Otherwise,
the passenger will be without protection from
the head restraint.<
Height
Adjust the head restraint so that its center is
approximately at ear level.
Distance
Adjust the distance so that the head restraint is
as close as possible to the back of the head.

you on the basis of what you see in the mirror;
otherwise, there is an increased risk of an acci-
dent.<1Adjustments

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 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 vehi-
cle represents a potential safety hazard.
Before leaving the car with the engine running,
place the transmission in neutral or move the
selector lever to position P and forcefully apply
the parking brake to prevent the car from mov-
ing.<
Avoid frequent starting in quick succes-
sion as well as repeated 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.

All washer nozzles are supplied with washer
fluid by the same reservoir.
Fill with water and, if required, with a washer
antifreeze, according to manufacturer's recom-
mendations.
Mix the water and antifreeze before filling
the washer fluid reservoir to make sure
the correct concentration is maintained.<
Capacity
Approx. 6.3 US quarts/6 liters.
Cruise control*
The concept
Cruise control is available for use at speeds of
approx. 20 mph or 30 km/h. The car then stores
and maintains the speed that you specify using
the lever on the steering column. In order to
maintain the specified speed, the system
brakes the vehicle when the engine braking
effect is insufficient on downhill gradients.
Do not use cruise control when driving at
constant speed is prevented by adverse
conditions, e.g. winding roads, dense traffic or
poor road conditions due to, e.g., snow, rain, ice
or loose surfaces. Otherwise, you could lose
control of the vehicle and cause an accident as a
result.<
Manual transmission
You can shift gears while cruise control is acti-
vated. The system is deactivated when you
drive at very low engine speeds for an extended
period.

4Resuming a speed stored beforehand
Maintaining current speed
Tap the lever, arrow 1, or pull it briefly, arrow 2.
The car's current speed is stored and main-
tained. It is displayed on the speedometer and
briefly in the instrument cluster.
On uphill gradients, it may prove impossible to
maintain the set speed if current engine power
output is insufficient. If the engine braking
effect is insufficient on downhill slopes, the sys-
tem will brake the vehicle slightly.
Increasing desired speed
Repeatedly press the lever to the resistance
point or beyond, arrow1, until the desired
speed is reached.
>Each time the lever is pressed to the resis-
tance point, the desired speed is increased
by approx. 1 mph or 1 km/h.
>Each time the lever is pressed beyond the
resistance point, the desired speed is
increased by up to 5 mph or 10 km/h.
The system stores and maintains the speed.
Accelerating using the lever
Accelerating slightly:
Press the lever to the resistance point, arrow 1,
until the desired speed is reached.
Accelerating significantly:
