RThe vehicle starts out more gentle, both
forward and reverse, except when driving
off with full throttle.
RTraction and driving stability are improved
on icy roads.
RUpshifts occur earlier even when you give
more gas. The engine then operates at
lower revolutions and the wheels are less
likely to spin.
Selecting program mode S means that
upshifts occur later.
One-touch gearshifting
With the transmission in drive position D and
driving in automatic program mode C, S, or
S+, you can limit or extend the gear range
using the gear selector lever or the steering
wheel gearshift control.
For information on using the gear selector
lever or the steering wheel gearshift control
in manual program mode M, see “Manual shift
program” (Y page 268).

Limiting gear range GWarning!
On slippery road surfaces, never downshift in
order to obtain braking action. This could
result in drive wheel slip and reduced vehicle
control. Your vehicle’s ABS will not prevent
this type of loss of control.

downshifting, the transmission will not shift
into a lower gear if the engine’s maximum
speed would be exceeded.

the transmission will upshift beyond any
gear range limit selected.

Control system
Introduction
The control system is activated as soon as the
starter switch is in position 2.
The control system enables you to call up
information about your vehicle and to change
vehicle settings.
For example, you can use the control system
to find out when your vehicle is next due for
maintenance service, to call up statistical
data on your vehicle, and much more.
GWarning!
A driver’s attention to the road and traffic
conditions must always be his/her primary
focus when driving.
For your safety and the safety of others,
selecting features through the multifunction
steering wheel should only be done by the
driver when traffic and road conditions permit
it to be done safely.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximately
14 m) every second.
The control system relays information to the
multifunction display.
Multifunction steering wheel
The displays in the multifunction display and
the settings in the control system are
controlled by using the buttons on the
multifunction steering wheel.

Driving systems
Introduction
This section describes the following driving
systems of your vehicle:
R Cruise control
R RACE START
R Hill-start assist system
R Parktronic system
R Rear view camera
The driving safety systems ABS, Adaptive
Brake, BAS, EBP, ESC and Trunk Wing are
described in the “Safety and security” section
( Y page 61).
Cruise control
The cruise control maintains the speed you
set for your vehicle automatically.
The use of the cruise control is recommended
for driving at a constant speed for extended
periods of time.
The currently set speed or last set speed
(“Resume” function) appears in the
multifunction display for approximately
5 seconds.
GWarning!
The cruise control is a convenience system
designed to assist the driver during vehicle
operation. The driver is and must always
remain responsible for the vehicle’s speed
and for safe brake operation.
Only use the cruise control if the road, traffic,
and weather conditions make it advisable to
travel at a constant speed.
R The use of the cruise control can be
dangerous on winding roads or in heavy
traffic because conditions do not allow safe
driving at a constant speed.
R The use of the cruise control can be
dangerous on slippery roads. Rapid
changes in tire traction can result in wheel
spin and loss of control.
R Deactivate the cruise control when driving
in fog.
The “Resume” function should only be
operated if the driver is fully aware of the
previously set speed and wishes to resume
this particular preset speed.GWarning!
The cruise control brakes automatically so
that the set speed is not exceeded.

than 1
/ 8 in (3 mm).
R When replacing individual tires, you should
mount new tires on the front wheels first
(on vehicles with same-sized wheels all
around).
Recommended tire inflation pressure
GWarning!
Follow recommended tire inflation pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly, adversely
affect handling and fuel economy, and are
more likely to fail from being overheated.
Do not overinflate tires. Overinflated tires can
adversely affect handling and ride comfort,
wear unevenly, increase stopping distance,
and result in sudden deflation (blowout)
because they are more likely to become
punctured or damaged by road debris,
potholes etc.
Do not overload the tires by exceeding the
specified load limit as indicated on the Tire
and Loading Information placard on the
driver’s door B-pillar. Overloading the tires
can overheat them, possibly causing a
blowout. Overloading the tires can also result
in handling or steering problems, or brake
failure.
Your vehicle is equipped with the Tire and
Loading Information placard located on the
driver’s door B-pillar ( Y page 334).
The tire inflation pressure should be checked
regularly. Only adjust the tire inflation
pressure on cold tires. The tires can be
considered cold if the vehicle has been
parked for at least 3 hours or driven less than
1 mile (1.6 km). Depending on the ambient
temperature, the driving speed and the tire
load, the tire temperature changes. When the
tire temperature changes by 18 ‡ (10†), the
tire inflation pressure will change by
approximately 10 kPa (0.1 bar, 1.5 psi). Keep
this in mind when checking tire inflation
pressure on warm tires and adjust the tire
pressure only if the tire inflation pressure is
too low for the current operating conditions.
If you check the tire inflation pressure when
the tires are warm, the reading will be higher
than the cold reading. This is normal. Do not
let air out to match the specified cold tire
inflation pressure. Otherwise, the tire will be
underinflated.
Follow recommended cold tire inflation
pressures listed on Tire and Loading
Information placard on the driver’s door
B-pillar.
Keeping the tires properly inflated provides
the best handling, tread life and riding
comfort.
In addition to the Tire and Loading
Information placard on the driver’s door
B-pillar, also consult the tire inflation
pressure label on the inside of the filler flap
for any additional information pertaining to
special driving situations. For more
information, see “Important notes on tire
inflation pressure” ( Y page 328).
i Data shown on Tire and Loading
Information placard example are for
illustration purposes only. Tire data are
specific to each vehicle and may vary from
data shown in the following illustration.
