Rear Wiper Operation — If Equipped
Rear Windshield Wiper Operation
Rotate the windshield wiper lever center ring
upwards to operate the rear window wiper as
follows:
In intermittent mode when the front window
wiper is not operating
In synchronous mode (at half the speed of
the front window wiper) when the front
window wiper is operating
In continuous mode while vehicle is in
REVERSE
With the windshield wipers on, and REVERSE
gear engaged, rear window wiping will be
continuous in the same way.
Rear Windshield Washer Operation
Pushing the windshield wiper lever forward
activates the rear window washer. Keep the
windshield wiper lever pushed for more than
quarter of a second to activate the rear window
wiper as well. When the windshield wiper lever
is released, the wipers will return to normal
operation.
CLIMATE CONTROLS
The Climate Control system allows you to
regulate the temperature, air flow, and direction
of air circulating throughout the vehicle. The
controls are located on the instrument panel
below the radio.
Manual Climate Control Descriptions And
Functions

Manual Climate Controls

System Maintenance
In Winter, the Climate Control system must be
turned on at least once a month for about
10 minutes.
Have the system inspected at an authorized
dealer before the Summer.
A/C Button
Push the A/C button to engage the
Air Conditioning (A/C). A LED will
illuminate when the A/C system is
engaged. The A/C can be
deselected manually without
disturbing the mode control selection.
The Air Conditioning (A/C) button allows the
operator to manually activate or deactivate the
air conditioning system. When the air
conditioning system is turned on, cool
dehumidified air will flow through the outlets
into the cabin.
For Manual Climate Controls, if the system is
in Mix, Floor or Defrost Mode, the A/C can be
turned off, but the A/C system shall remain
active to prevent fogging of the windows.
If fog or mist appears on the windshield or
side glass, select Defrost mode, and increase
blower speed if needed.
If your air conditioning performance seems
lower than expected, check the front of the
A/C condenser (located in front of the radi -
ator), for an accumulation of dirt or insects.
Clean with a gentle water spray from the front
of the radiator and through the condenser.

Recirculation Button
Press and release this button to
change the system between
recirculation mode and outside air
mode. The Recirculation indicator and
the A/C indicator illuminate when the
Recirculation button is pressed. Recirculation
can be used when outside conditions such as
smoke, odors, dust, or high humidity are
present. Recirculation can be used in all modes.
Recirculation may be unavailable (button on the
touchscreen greyed out) if conditions exist that
could create fogging on the inside of the
windshield. The A/C can be deselected
manually without disturbing the mode control
selection. Continuous use of the Recirculation
mode may make the inside air stuffy and
window fogging may occur. Extended use of this
mode is not recommended.
In cold weather, use of Recirculation mode may
lead to excessive window fogging. The
Recirculation feature may be unavailable if
conditions exist that could create fogging on the
inside of the windshield.
Front Defrost Button
Use Defrost mode with maximum
temperature settings for best
windshield and side window
defrosting and defogging. Turn the
knob to the Front Defrost position. Air comes
from the windshield and side window demist
outlets.
Rear Defrost Button — If Equipped
Push and release the Rear Defrost
Control button to turn on the rear
window defroster and the heated
outside mirrors (if equipped). An
indicator will illuminate when the rear window
defroster is on. The rear window defroster
automatically turns OFF after 20 minutes.
Temperature Control
Use this control to regulate the
temperature of the air inside the
passenger compartment. Rotating
the knob counterclockwise, from top
center into the blue area of the scale, indicates
cooler temperatures. Rotating the knob
clockwise, into the red area, indicates warmer
temperatures.
Blower Control
There are four blower speeds. Use
this control to regulate the amount of
air forced through the system in any
mode you select. The blower speed
increases as you move the control clockwise
from the OFF position.
Mode Control
Rotate this control to change the
airflow distribution mode. The airflow
distribution mode can be adjusted so
air comes from the instrument panel
outlets, floor outlets, defrost outlets and demist
outlets. The Mode settings are as follows:
Panel Mode
Air comes from the outlets in the
instrument panel. Each of these
outlets can be individually adjusted to
direct the flow of air. The air vanes of
the center outlets and outboard outlets can be
moved up and down or side to side to regulate
airflow direction. There is a shut off wheel
located below the air vanes to shut off or adjust
the amount of airflow from these outlets.

21_VM_OM_EN_USC_t.book Page 32

GETTING TO KNOW YOUR VEHICLE33
Bi-Level Mode
Air comes from the instrument panel
outlets and floor outlets. A slight
amount of air is directed through the
defrost and side window demister
outlets.
NOTE:
Bi-Level mode is designed under comfort condi -
tions to provide cooler air out of the panel
outlets and warmer air from the floor outlets.
Floor Mode
Air comes from the floor outlets. A
slight amount of air is directed
through the defrost and side window
demister outlets.
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.
Operating Tips
NOTE:
Refer to the chart at the end of this section for
suggested control settings for various weather
conditions.
Summer Operation
The engine cooling system must be protected
with a high-quality antifreeze coolant to provide
proper corrosion protection and to protect
against engine overheating. OAT coolant
(conforming to MS.90032) is recommended
Ú page 259.
Winter Operation
To ensure the best possible heater and
defroster performance, make sure the engine
cooling system is functioning properly and the
proper amount, type, and concentration of
coolant is used Ú page 259. Use of the Air
Recirculation mode during Winter months is not
recommended because it may cause window
fogging.
Vacation/Storage
Any time you store your vehicle or keep it out of
service (i.e., vacation) for two weeks or more,
run the air conditioning system at idle for about
five minutes in fresh air with the blower setting
on high. This will ensure adequate system
lubrication to minimize the possibility of
compressor damage when the system is started
again.
Window Fogging
Vehicle windows tend to fog on the inside of the
glass in mild, rainy and/or humid weather. To
clear the windows, select Defrost or Mix mode
and increase the front blower speed. Do not use
the Recirculation mode without A/C for long
periods, as fogging may occur.

Outside Air Intake
Make sure the air intake, located directly in
front of the windshield, is free of obstructions,
such as leaves. Leaves collected in the air
intake may reduce airflow, and if they enter the
air distribution box, they could plug the water
drains. In Winter months, make sure the air
intake is clear of ice, slush, and snow.
Cabin Air Filter
The Climate Control system filters out dust and
pollen from the air. Contact an authorized
dealer to service your cabin air filter, and to
have it replaced when needed.
Operating Tips Chart
CAUTION!
Failure to follow these cautions can cause
damage to the heating elements:
Use care when washing the inside of the
rear window. Do not use abrasive window
cleaners on the interior surface of the
window. Use a soft cloth and a mild
washing solution, wiping parallel to the
heating elements. Labels can be peeled off
after soaking with warm water.
Do not use scrapers, sharp instruments, or
abrasive window cleaners on the interior
surface of the window.
Keep all objects a safe distance from the
window.

WARNING LIGHTS AND MESSAGES
The warning/indicator lights will illuminate in
the instrument panel together with a dedicated
message and/or acoustic signal when
applicable. These indications are indicative and
precautionary and as such must not be
considered as exhaustive and/or alternative to
the information contained in the Owner’s
Manual, which you are advised to read carefully
in all cases. Always refer to the information in
this chapter in the event of a failure indication.
All active telltales will display first if applicable.
The system check menu may appear different based upon equipment options and current
vehicle status. Some telltales are optional and
may not appear.
Red Warning Lights
Air Bag Warning Light
This light will turn on for four to eight
seconds as a bulb check when the
ignition is placed in the ON/RUN or
MAR/ON/RUN position. If the light is
either not on during startup, stays on, or turns
on while driving, have the system inspected by
an authorized dealer as soon as possible. This
light will illuminate with a single chime when a
fault with the Air Bag Warning Light has been
detected, it will stay on until the fault is cleared.
If the light comes on intermittently or remains
on while driving, have an authorized dealer
service the vehicle immediately.
Brake Warning Light
This warning light monitors various
brake functions, including brake fluid
level and parking brake application. If
the brake light turns on it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a
problem with the Anti-Lock Brake System
reservoir.
3

21_VM_OM_EN_USC_t.book Page 49

50GETTING TO KNOW YOUR INSTRUMENT PANEL
If the light remains on when the parking brake
has been disengaged, and the fluid level is at
the full mark on the master cylinder reservoir, it
indicates a possible brake hydraulic system
malfunction or that a problem with the Brake
Booster has been detected by the Anti-Lock
Brake System (ABS) / Electronic Stability
Control (ESC) system. In this case, the light will
remain on until the condition has been
corrected. If the problem is related to the brake
booster, the ABS pump will run when applying
the brake, and a brake pedal pulsation may be
felt during each stop.
The dual brake system provides a reserve
braking capacity in the event of a failure to a
portion of the hydraulic system. A leak in either
half of the dual brake system is indicated by the
Brake Warning Light, which will turn on when
the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is
corrected. NOTE:
The light may flash momentarily during sharp
cornering maneuvers, which change fluid level
conditions. The vehicle should have service
performed, and the brake fluid level checked.
If brake failure is indicated, immediate repair is
necessary.
Vehicles equipped with the Anti-Lock Brake
System (ABS) are also equipped with Electronic
Brake Force Distribution (EBD). In the event of
an EBD failure, the Brake Warning Light will turn
on along with the ABS Light. Immediate repair to
the ABS system is required.
Operation of the Brake Warning Light can be
checked by turning the ignition switch from the
OFF position to the ON/RUN position. The light
should illuminate for approximately two seconds. The light should then turn off unless
the parking brake is applied or a brake fault is
detected. If the light does not illuminate, have
the light inspected by an authorized dealer.
The light also will turn on when the parking
brake is applied with the ignition switch in the
ON/RUN position.
NOTE:
This light shows only that the parking brake is
applied. It does not show the degree of brake
application.
Battery Charge Warning Light
This warning light will illuminate when
the battery is not charging properly. If
it stays on while the engine is running,
there may be a malfunction with the
charging system. Contact an authorized dealer
as soon as possible. This indicates a possible
problem with the electrical system or a related
component.
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may
have failed. It will take longer to stop the
vehicle. You could have a collision. Have the
vehicle checked immediately.
