Residual heat mode
The system uses the warmth
stored in the engine to heat the
interior when the ignition is off,
for instance, while the vehicle
is stopped at a school to pick
up a child.
You can adjust the automatic climate con-
trol's settings when the ignition lock is in
the radio mode. The system blows heated
air into the interior in accordance with the
selected distribution pattern while the igni-
tion is off.
Provided that the engine has warmed
to its normal operating temperature
and the battery is charged, you can use this
function for up to 15 minutes after switch-
ing off the ignition. The LED within the but-
ton lights up to confirm compliance with
both of these conditions.<
Front ventilation
You can adjust the vent outlets for the
upper body to suit your personal require-
ments.
You can use the serrated dials 1 to open
and close the outlets through an infinitely-
variable range, while the serrated dials 2
allow you to adjust the airflow direction.
Ventilation for cooling
Adjust the vents to direct the flow of cool
air in your direction, for instance, if the inte-
rior has become too warm, etc.
Draft-free ventilation
Set the vent outlets so that the air flows
past you and is not directed straight at you. You can also individually adjust the air
temperature of the air vents for the
upper body area in the Control Center,
refer to page 107.
If the ventilation grill is completely closed,
the vehicle interior is ventilated indirectly
by air vents on the upper side of the cock-
pit.<
Ventilation for storage compartment
in front armrest
You can use the serrated dial in the storage
compartment to open and close the vent.
Depending upon the temperatures
selected at the rear dials, high tem-
peratures may occur in the storage com-
partment. Close the vent as required.<
Ventilation in the rear
The serrated dials 1 allow you to open and
close the ventilation outlets through an infi-
nitely-variable range.
You can adjust the airflow direction using
the levers 2.
The serrated dials 3
* control the amount of
cooled air in the flow from the vent outlets:
Turn towards blue: colder
Turn towards red: warmer.

to as hydroplaning, and is characterized
by a partial or complete loss of contact
between tires and road surface, ultimately
undermining your ability to steer and brake
the vehicle.<
Driving through water
Do not drive through water on the
road if it is deeper than 1 ft/30 cm,
and then only at walking speed at the most.
Otherwise, the vehicle's engine, the electri-
cal systems and the transmission may be
damaged.<
Brake system
Braking with ABS
The best way to achieve the best response
from the ABS is to apply maximum pres-
sure to the brake pedal Ð panic stop. Since
the vehicle maintains steering responsive-
ness, you can nevertheless avoid possible
obstacles with a minimum of steering
effort.
Pulsation at the brake pedal combines with
sounds from the hydraulic circuits to indi-
cate to the driver that ABS is in its active
mode.
Do not drive with your foot resting on
the brake pedal. Otherwise, even light
but consistent pedal pressure can lead to
high temperatures, brake wear and possi-
bly even brake failure.<
Disc brakes
Driving in wet conditions
While driving in wet conditions and in
heavy rain, it is a good idea to apply light
pressure to the brake pedal every few
miles. Monitor traffic conditions to ensure
that this maneuver does not endanger
other road users. The heat generated in this
process helps dry the pads and rotors to
ensure that full braking efficiency will then
be available when you need it.
Hills
You can retain full and unimpaired braking
efficiency by downshifting to a gear in
which only minimal brake applications are
needed when descending long or steep
downhill stretches.
You can further enhance the engine's
braking effect by selecting a lower gear
in the automatic transmission's manual
mode, downshifting as far as first gear
on extremely steep stretches, refer to
page 67. This strategy helps you avoid
placing excessive loads on the brake sys-
tem.
Never allow the vehicle to coast with
the transmission in Neutral Ð or with
the engine switched off Ð as there is no
engine braking when the transmission is in
Neutral, and no power-assist for brakes
and steering when the engine is not run-
ning.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
accelerator and brake pedals and obstruct
their movement.<
Corrosion
When the vehicle is driven only occasion-
ally, during extended periods when the
vehicle is not used at all, and in operating
conditions where brake applications are
less frequent, there is an increased ten-
dency for corrosion to form on rotors, while
contaminants accumulate on the brake
pads. This occurs because the minimal
pressure which must be exerted by the
pads during brake applications to clean the
rotors is not reached.
Should corrosion form on the brake rotors,
the brakes will tend to respond with a pul-
sating effect that even extended applica-
tion will fail to cure.
Brake pads
If the brake pad wear warning lamp
appears in the Check Control,
accompanied by a text. Please take
careful note of the additional information on
the Control Display.

Checking oil level
1.Park the vehicle on a level surface
2.Switch the engine off after it has
reached normal operating temperature 3.After approx. 5 minutes, pull the dip-
stick out and wipe it off with a clean lint-
free cloth, paper towel, or similar mate-
rial
4.Carefully push the dipstick all the way
into the guide tube and pull it out again
5.The oil should extend to between the
two marks on the dipstick.
As is the case with fuel economy, the rate
at which the engine uses oil is strongly
influenced by driving style and operating
conditions.
