Power front seats*
The power front seats can be adjusted in a num-
ber of different ways for optimal comfort and
ergonomics. The power seats can be moved for-
ward/backward and up/down. The height and
length* of the seat cushion and the tilt of the
backrest can be adjusted. Lumbar support can
be adjusted up, down, forward and backward.
The power seats have an overload protector that
is triggered if a seat is blocked by any object. If
this occurs, remove the object and attempt to
adjust the seat again.
The power seats can be adjusted for a certain
period of time after the door is unlocked without
the engine running. The seats can always be
adjusted while the engine is running. They can
also be adjusted for a short period after the
engine is turned off.

The climate in the passenger compartment can
be maintained when the vehicle is parked, e.g. if
the engine is turned off but the driver or passen-
gers remain in the vehicle. This function can only be direct-started.
The function utilizes several of the vehicle's sys-
tems:
• Residual heat from the engine is used to
help heat the passenger compartment to a
comfortable temperature.
• In warm weather, the ventilation system cools
the passenger compartment by blowing air in
from outside.
NOTE Climate comfort maintenance will be deacti-
vated if the vehicle is locked from the outside
in order to avoid using residual engine heat
unnecessarily. This function is intended to be
used to maintain climate comfort when the
driver or a passenger remains in the vehicle
after the engine is turned off.

DRIVER SUPPORT
288Managing Cruise Control speed
Cruise Control (CC 29
) 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 to
the 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 to
the set speed when the accelerator pedal is
released.
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 to
the 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 to
the set speed when the accelerator pedal is
released.
Using engine braking instead of
applying the brakes
Cruise Control regulates speed by lightly applying
the brakes. On downgrades, it can sometimes be
desirable to roll a bit faster and let speed be
reduced instead by engine braking alone. The
driver 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 the
engine braking function.
How drive mode affects cruise controlThe way the cruise control maintains the vehicle's
speed can vary depending on the selected drive
mode 30

at the same time.
The higher speed is the set
speed for your vehicle and the
lower speed is the speed of the
vehicle ahead (target vehicle).
