Brake Assist System
The brake enhancing system, Brake Assist
System (BAS

), helps increase braking force and
thereby reduce braking distance.
The system monitors the driver's braking habits
and increases braking force when necessary.
Braking force can be increased up to the point at
which the ABS intervenes. The function is deacti-
vated when pressure on the brake pedal is
decreased.

Brakes (p. 439) Braking on wet roads
Prolonged driving in heavy rain without braking
may cause braking effect to be slightly delayed
the first time the brakes are applied.
This may also occur after washing the vehicle. It
will then be necessary to apply greater pressure
to the brake pedal. You should therefore maintain
a greater distance to the vehicle ahead.
Firmly apply the brakes after washing the vehicle
or driving on wet roads. This helps warm up the
brake discs, enabling them to dry more quickly
and protecting them against corrosion. Consider
the current traffic situation when braking.

Braking on salted roads (p. 441) Braking on salted roads
When driving on salted roads, a layer of salt may
form on the brake discs and brake pads.
This could increase stopping distance. Maintain
an extra large safety distance to the vehicle
ahead. Make sure to also:
Apply the brakes from time to time to help
remove salt. Make sure braking does not
pose a risk to any other road users.
Gently apply the brakes when you have fin-
ished driving and before driving again.

454 Starting and stopping the
combustion engine in Twin Engine
vehicles
An advanced control system determines the dis-
tance that the vehicle can be driven on the com-
bustion engine, electric motor, or both at the
same time. When driving on only the electric
motor, the vehicle may automatically start the
combustion engine due to outside circumstan-
ces, e.g. low ambient temperatures. This is com-
pletely normal. The combustion engine will also
always start when the hybrid battery is nearly
fully discharged.
Climate settings at low temperaturesAt low ambient temperatures, the combustion
engine will sometimes start automatically to help
achieve the desired passenger compartment
temperature and air quality. The amount of time
the combustion engine is running can be affec-
ted by:
lowering the temperature
reducing blower speed
activating Pure drive mode.
Using the electric motor in hot or cold
weather
At very low or high ambient temperatures, the
electric motor's driving range and power may be
reduced and affect how often the combustion
engine automatically starts.
Emission control systemTo help ensure that the emission control system
functions optimally, the combustion engine will
run for several minutes after it is started. The
amount of time the combustion engine needs to
be used varies depending on the temperature of
the three-way catalytic converter.
WARNING California Proposition 65
Operating, servicing and maintaining a pas-
senger vehicle can expose you to chemicals
including engine exhaust, carbon monoxide,
phthalates, and lead, which are known to the
State of California to cause cancer and birth
defects or other reproductive harm. To mini-
mize exposure, avoid breathing exhaust, do
not idle the engine except as necessary, serv-
ice your vehicle in a well ventilated area and
wear gloves or wash your hands frequently
when servicing your vehicle. For more infor-
mation go to www.P65Warnings.ca.gov/

plify the driving experience in certain types of sit-
uations.
Drive modes enable easy access to the vehicle's
many functions and settings in different driving
situations. The following systems are adapted to
help optimize driving characteristics in each drive
mode:

Leveling control* and suspension
The vehicle's leveling control system adjusts the
suspension and shock absorbers automatically
to help provide good comfort and control while
driving. Leveling can also be controlled manually
to facilitate loading or getting in and out of the
vehicle.
Pneumatic suspension and shock
absorbers
The system is adapted to the selected drive
mode and vehicle speed. The pneumatic suspen-
sion reduces the vehicle's ground clearance at
higher speeds to reduce air resistance and
increase stability. The shock absorbers are nor-
mally set to provide the best possible comfort
and are adjusted continuously according to the
road surface and the vehicle's acceleration, brak-
ing and cornering. The instrument panel indicates
when the suspension level is
being adjusted.The following apply if a door or the tailgate is
opened:
If a door is opened, the level can only be
adjusted upwards.
If the tailgate is open, the level can only be
adjusted downwards.
ParkingWhen parking, make sure that there is adequate
space above and below the vehicle since ground
clearance may vary depending on e.g. ambient temperature, how the vehicle is loaded, if loading
mode is used, which drive mode is selected after
the engine is started, etc.
The level may also be adjusted a period after the
vehicle is parked. This is to compensate for any
height changes that may occur due to tempera-
ture changes in the air springs when the vehicle
cools.
TransportingWhen transporting the vehicle on a ferry, train or
truck, only secure (lash) the vehicle around the
tires, not using any other parts of the chassis.
Changes in the pneumatic suspension may occur
during transport, which could adversely affect the
lashing and result in damage.

Recommended tire pressure
The tire pressure placard on the driver's side B
pillar (between the front and the rear door) indi-
cates tire pressure for different loads and speed
conditions. The decal specifies the designation for the fac-
tory-mounted tires on the vehicle, as well as load
limits and inflation pressures.
Related information

Checking tire pressure (p. 567)
Approved tire pressure (p. 675) Tire pressure monitoring system*
The tire pressure monitoring system 6
provides a
warning symbol in the instrument panel if pres-
sure is too low in one or more tires. Symbol
Explanation This symbol illuminates to indicate
low inflation pressure.
If there is a system malfunction, the
inflation pressure warning symbol
will flash for approximately one
minute and then glow steadily.
System descriptionThe tire pressure monitoring system measures
differences in rotational speed between the
wheels through the ABS system to determine if
the tires are properly inflated. If inflation pressure
in a tire is too low, its diameter (and consequently
its rotational speed) changes. By comparing the
tires with each other, the system can determine if
the pressure in one or more tires is too low.
General information about the tire pressure
monitoring system
In the following description, the tire monitoring
system is generally referred to as TPMS.
Each tire, including the spare (if provided)
7
should be checked monthly when cold and infla- ted to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure label,
you should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres-
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when the
low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible,
and inflate them to the proper pressure.
Driving on a significantly under-inflated tire cau-
ses the tire to overheat and can lead to tire fail-
ure. Under-inflation also reduces fuel efficiency
and tire tread life, and may affect the vehicle's
handling and stopping ability. Please note that
the TPMS is not a substitute for proper tire main-
tenance, and it is the driver's responsibility to
maintain correct tire pressure, even if under-infla-
tion has not reached the level to trigger illumina-
tion of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when the
system is not operating properly. The TPMS mal-
function indicator is combined with the low tire

Start battery
The vehicle has a single-pole electrical system
that uses the chassis and engine mount as con-
ductors.
The start battery is used to start the electrical
system and power electrical equipment in the
vehicle. The hybrid battery is used to start the
combustion engine.
The start battery should only be replaced by a
workshop 15
.
The start battery is a 12 V AGM (Absorbed Glass
Mat) battery, dimensioned for regenerative charg-
ing and to support the function of the vehicle's
various systems.
The service life and performance of the start bat-
tery are affected by factors such as driving style,
driving conditions, climate, battery discharges,
number of starts, etc.
Never disconnect the start battery while the
engine is running.
Make sure the cables to the start battery are
correctly connected and the clamps are
securely tightened.
