amount of air is directed through the
defrost and side window demister
outlets. This setting heats the
passenger compartment the quickest.
Mix Mode
Air is directed through the floor, defrost,
and side window demister outlets. This
setting works best in cold or snowy
conditions that require extra heat to the
windshield. This setting is good for maintaining
comfort while reducing moisture on the
windshield.
Front Defrost And Panel Mode
Air flow is distributed between the
windshield demisting/defrosting vents
and side/central dashboard vents. This
setting allows air to flow to the
windshield on sunny days.
Front Defrost And Bi-Level Mode
Air flow is distributed to all vents.

Tire Pressure Low Warning Light
The indicator light will illuminate to
indicate that the tire pressure is lower
than the recommended value and/or
that slow pressure loss is occurring. In
these cases, optimal tire duration and fuel
consumption may not be guaranteed.
In any situation in which the message on the
display is “See Manual”

Ú
page 142.
Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a
message is displayed to indicate that
the tire pressure is lower than the
recommended value and/or that slow
pressure loss is occurring. In these cases, optimal
tire duration and fuel consumption may not be
guaranteed.
Should one or more tires be in the condition
mentioned previously, the display will show the
indications corresponding to each tire.
Each tire, including the spare (if provided), should
be checked monthly when cold and inflated 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 TPMS that illuminates a low tire
pressure telltale when one or more of your tires is
significantly underinflated. 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 underinflated tire causes the
tire to overheat and can lead to tire failure.
Underinflation 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 maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if underinflation has not reached the level to
trigger illumination 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
malfunction indicator is combined with the low
tire pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi
-
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the
malfunction exists. When the malfunction
indicator is illuminated, the system may not be
able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a
variety of reasons, including the installation of
replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or more tires or wheels
on your vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to
continue to function properly.
Rear Fog Lights
The indicator illuminates when the rear
fog light is activated.
Engine Check/Malfunction Indicator Light
(MIL)
In normal conditions, when the ignition
is cycled to ON, the indicator light
illuminates, but it should turn off as
soon as the engine is started.
CAUTION!
Do not continue driving with one or more flat
tires as handling may be compromised. Stop
the vehicle, avoiding sharp braking and
steering. If a tire puncture occurs, repair
immediately using the dedicated tire repair kit
and contact an authorized dealer as soon as
possible.
WARNING!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures
and warning have been established for the tire
size equipped on your vehicle. Undesirable
system operation or sensor damage may
result when using replacement equipment
that is not of the same size, type, and/or style.
Aftermarket wheels can cause sensor
damage. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System
(TPMS) sensor to become inoperable. After
using an aftermarket tire sealant it is
recommended that you take your vehicle to an
authorized dealership to have your sensor
function checked.

NOTE:
Do not use the vehicle until the failure has been
solved. The turning on of the telltale does not indi-
cate the amount of oil in the engine. The oil level
can be checked on the display upon entering the
vehicle and also by activating the “Oil level” func -
tion on the Information and Entertainment
System.
Contact an authorized dealer as soon as
possible.
Trunk Lid Not Properly Shut
The telltale turns on when the trunk lid
is not properly closed, along with the
icon, an image of the vehicle with an
open trunk lid appears on the display.

If Equipped
The telltale is illuminated only for a
limited time.

NOTE:
After the first indication, each time the engine is
started the symbol will continue to illuminate as
described previously until the oil is changed. If the telltale flashes, this does not mean that
there is a fault on the vehicle, rather it simply
reports that it is now necessary to change the oil
as a result of regular use of the vehicle. The
deterioration of engine oil is accelerated by using
the vehicle for short drives, preventing the engine
from reaching operating temperature.
Contact an authorized dealer as soon as
possible.

CAUTION!
Deteriorated engine oil should be replaced as
soon as possible after the symbol is switched
on, and never more than 500 miles (805 km)
after it first switches on. Failure to observe the
above may result in severe damage to the
engine and invalidate the New Vehicle Limited
Warranty. When this symbol comes on, it does
not mean that the level of engine oil is low, so
if it flashes you do not need to top up the
engine oil.
