Driver support systems
The vehicle is equipped with a number of driver support systems that can provide the driver withactive or passive assistance in various situations.
The system can, for example, help the driver maintain a set speed or a set time interval to thevehicle ahead, help prevent a collision by warningthe driver and applying the brakes, or assist thedriver while parking. Some of the systems are standard and others are options. This also varies from market to market.

Speed-dependent steering wheelresistance
Speed-dependent power steering increases the steering wheel resistance in pace with the vehi-cle's speed to give the driver an enhanced feel-ing of control and stability.
Steering may feel stiffer on highways. When parking and at low speeds, it will be easier tomove the steering wheel.
NOTE
In some situations, the power steering may become too hot and require temporary cool-ing – during such time the power steering willwork at reduced output and the steeringwheel may feel more difficult to move. In parallel with the temporarily reduced steer- ing assistance, the driver display shows amessage as well as a STEERING WHEELsymbol.

Electronic Stability Control Sportmode
The ESC 5
system is always activated and can-
not be switched off. However, the driver can select
ESC Sport Mode, which offers more
active driving characteristics.
With the ESC Sport Mode sub-function
selected, intervention from ESC is reduced and more lateral movement is permitted, giving thedriver more control of the vehicle than usual. When
ESC Sport Mode is selected, ESC may
seem to be disabled even though it is often assisting the driver.
ESC Sport Mode also helps provide maximum
traction if the vehicle gets stuck or is driving on a loose surface such as deep snow or loose sand.

Cruise Control limitations
On steep downgrades, the Speed limiter's brak- ing capacity may not be sufficient and the setmaximum speed may be exceeded. If this hap- pens,
Speed limit exceeded will be displayed in
the instrument panel to alert the driver.
NOTE
A text message on exceeded max. speed is activated if the speed is exceeded by at least3 km/h (ca 2 mph).

Automatic Speed Limiter
The Automatic Speed Limiter (ASL 15
) function
helps the driver adapt the vehicle's maximum speed to the posted speed limits.
The Speed Limiter (SL 16
) function can be
switched to Automatic Speed Limiter (ASL). The Automatic Speed Limiter function uses speed information from the Road Sign Informa- tion function 17
to automatically adapt the vehi-
cle's maximum speed.

Managing Cruise Control speedCruise Control (CC 26
) can be set to various
speeds.
Setting/changing set speed
Note: This illustration is general and details may vary depending on model.
For vehicles with only CC
–Change a set speed by pressing the (1)
or
(3) buttons briefly or by pressing and
holding them:
• Press briefly
: Press briefly: each press
changes the speed in +/- 1 mph (+/- 1 km/h) increments.
• Press
and hold: Release the button when
the set speed indicator (4) has moved tothe desired speed. •
The most recently set speed will be stored.
If speed is increased by depressing the accelera- tor pedal while pressing the
(1) button on
the steering wheel, the vehicle's speed when the button is pressed will be stored as the set speed. Temporarily increasing speed using the accelera- tor pedal, e.g. when passing another vehicle, willnot affect the setting. The vehicle will return tothe set speed when the accelerator pedal isreleased.
For vehicles with both CC and ACC
–Change a set speed by pressing the (1)
or
(3) buttons briefly or by pressing and
holding them:
• Press briefly
: Press briefly: each press
changes the speed in +/- 5 mph (+/- 5 km/h) increments.
• Press
and hold: Release the button when
the set speed indicator (4) has moved tothe desired speed.
• The most recently set speed will be stored.
If speed is increased by depressing the accelera- tor pedal while pressing the
(1) button on
the steering wheel, the vehicle's speed when the button is pressed will be stored as the set speed. Temporarily increasing speed using the accelera- tor pedal, e.g. when passing another vehicle, will not affect the setting. The vehicle will return tothe set speed when the accelerator pedal isreleased.
Using engine braking instead of
applying the brakes
Cruise Control regulates speed by lightly applyingthe brakes. On downgrades, it can sometimes bedesirable to roll a bit faster and let speed bereduced instead by engine braking alone. Thedriver can temporarily disengage the Cruise Con-trol braking function. To disengage CC:
–Press the accelerator pedal about halfway down and then release it.
> Cruise Control will automatically disen- gage the automatic brake function and speed will only be reduced using theengine braking function.
How drive mode affects cruise controlThe way the cruise control maintains the vehicle'sspeed can vary depending on the selected drive mode 27
