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.

Instrument Cluster Descriptions

1. Speedometer

Indicates vehicle speed.
2. Fuel Gauge
The pointer shows the level of fuel in the
fuel tank when the ignition switch is in
the ON/RUN position.
 The fuel pump arrow symbol points
to the side of the vehicle where the
fuel door is located.
3. Temperature Gauge
The temperature gauge shows engine
coolant temperature. Any reading within
the normal range indicates that the
engine cooling system is operating satis -
factorily.
The pointer will likely indicate a higher
temperature when driving in hot weather
or up mountain grades. It should not be
allowed to exceed the upper limits of the
normal operating range. 4. Tachometer
Indicates the engine speed in revolutions
per minute (RPM x 1000).
5. Instrument Cluster Display
When the appropriate conditions exist,
this display shows the instrument cluster
display messages Ú page 44.
Instrument Cluster Display Location

INSTRUMENT CLUSTER DISPLAY
Your vehicle will be equipped with an
instrument cluster display, which offers useful
information to the driver. With the ignition in the
OFF mode, opening/closing of a door will
activate the display for viewing, and display the
total miles, or kilometers, in the odometer. The
steering wheel mounted controls allow you to
scroll through the main menus and submenus.
You can access the specific information you
want and make selections and adjustments.
WARNING!
A hot engine cooling system is dangerous.
You or others could be badly burned by steam
or boiling coolant. You may want to call an
authorized dealer for service if your vehicle
overheats Ú
page 229.
CAUTION!
Driving with a hot engine cooling system
could damage your vehicle. If the
temperature gauge reads “H,” pull over and
stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops
back into the normal range. If the pointer
remains on the “H,” turn the engine off
immediately and call an authorized dealer for
service.

Door Open Warning Light
This indicator will illuminate when one
or more door(s) are not fully closed.
NOTE:
If the vehicle is moving and a door is opened,
there will also be a single chime.
Electronic Throttle Control (ETC) Warning
Light
This warning light will illuminate to
inform of a problem with the ETC
system. If a problem is detected while
the vehicle is running, the light will
either stay on or flash depending on the nature
of the problem. Cycle the ignition when the
vehicle is safely and completely stopped and
the transmission is placed in the PARK (P)
position. The light should turn off. If the light
remains on with the vehicle running, your
vehicle will usually be drivable; however, see an
authorized dealer for service as soon as
possible. If the light continues to flash when the vehicle is
running, immediate service is required and you
may experience reduced performance, an
elevated/rough idle, or engine stall and your
vehicle may require towing. The light will come
on when the ignition is placed in the ON/RUN or
MAR/ON/RUN position and remain on briefly as
a bulb check. If the light does not come on
during starting, have the system checked by an
authorized dealer.Engine Coolant Temperature Warning Light
This warning light warns of an
overheated engine condition. If the
engine coolant temperature is too
high, this indicator will illuminate and
a single chime will sound. If the temperature
reaches the upper limit, a continuous chime will
sound for four minutes or until the engine is
able to cool, whichever comes first.
If the light turns on while driving, safely pull over
and stop the vehicle. If the Air Conditioning
(A/C) system is on, turn it off. Also, shift the
transmission into NEUTRAL (N) and idle the
vehicle. If the temperature reading does not
return to normal, turn the engine off
immediately and call for service Ú page 207.
Oil Pressure Warning Light
This warning light will illuminate to
indicate low engine oil pressure. If the
light turns on while driving, stop the
vehicle, shut off the engine as soon as
possible, and contact an authorized dealer. A
chime will sound when this light turns on.
Do not operate the vehicle until the cause is
corrected. This light does not indicate how
much oil is in the engine. The engine oil level
must be checked under the hood.
Transmission Temperature Warning Light — If
Equipped
This warning light will illuminate to
warn of a high transmission fluid
temperature. This may occur with
strenuous usage such as trailer
towing. If this light turns on, stop the vehicle and
run the engine at idle or slightly faster, with the
transmission in PARK (P) or NEUTRAL (N), until
the light turns off. Once the light turns off, you
may continue to drive normally.

66STARTING AND OPERATING
DRIVE (D)
This range should be used for most city and
highway driving. It provides the smoothest
upshifts and downshifts, and the best fuel
economy. The transmission automatically
upshifts through all forward gears.
When frequent transmission shifting occurs
(such as when operating the vehicle under
heavy loading conditions, in hilly terrain,
traveling into strong head winds, or while towing
a heavy trailer), use the Electronic Range Select
(ERS) shift control to select a lower gear range
Úpage 67. Under these conditions, using a
lower gear range will improve performance and
extend transmission life by reducing excessive
shifting and heat buildup.
If the transmission temperature exceeds
normal operating limits, the transmission
controller may modify the transmission shift
schedule, reduce engine torque, and/or expand
the range of torque converter clutch
engagement. This is done to prevent
transmission damage due to overheating.
If the transmission becomes extremely hot, the
“Transmission Temperature Warning Light” may
illuminate and the transmission may operate
differently until the transmission cools down. During cold temperatures, transmission
operation may be modified depending on
engine and transmission temperature as well
as vehicle speed. This feature improves warm
up time of the engine and transmission to
achieve maximum efficiency. Engagement of
the torque converter clutch, and shifts into
8th or 9th gear, are inhibited until the
transmission fluid is warm Ú
page 67. Normal
operation will resume once the transmission
temperature has risen to a suitable level.
Transmission Limp Home Mode
Transmission function is monitored
electronically for abnormal conditions. If a
condition is detected that could result in
transmission damage, Transmission Limp
Home Mode is activated. In this mode, the
transmission may operate only in a fixed gear,
or may remain in NEUTRAL. The Malfunction
Indicator Light (MIL) may be illuminated. Limp
Home Mode may allow the vehicle to be driven
to an authorized dealer for service without
damaging the transmission. In the event of a momentary problem, the
transmission can be reset to regain all forward
gears by performing the following steps:

1. Stop the vehicle.

2. Shift the transmission into PARK.
3. Turn the ignition OFF.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the
problem is no longer detected, the
transmission will return to normal
operation.
NOTE:
Even if the transmission can be reset, we
recommend that you visit an authorized dealer
at your earliest possible convenience. An autho -
rized dealer has diagnostic equipment to
assess the condition of your transmission. If the
transmission cannot be reset, authorized dealer
service is required.

21_VM_OM_EN_USC_t.book Page 66

IN CASE OF EMERGENCY207
Disconnecting The Jumper Cables

1. Disconnect the negative
(-)
end of the
jumper cable from the engine ground of
the vehicle with the discharged battery.
2. Disconnect the opposite end of the negative (-) jumper cable from the
negative (-) post of the booster battery.

3. Disconnect the positive (+) end of the
jumper cable from the positive (+) post of
the booster battery.

4. Disconnect the opposite end of the positive (+) jumper cable from the
positive (+) post of the vehicle with the
discharged battery.

If frequent jump starting is required to start your
vehicle you should have the battery and
charging system inspected at an authorized
dealer.
IF YOUR ENGINE OVERHEATS
If the vehicle is overheating, it will need to be
serviced by an authorized dealer.
In any of the following situations, you can
reduce the potential for overheating by taking
the appropriate action.
On the highways — slow down.
In city traffic — while stopped, place the trans -
mission in NEUTRAL (N), but do not increase
the engine idle speed while preventing
vehicle motion with the brakes. NOTE:
There are steps that you can take to slow down
an impending overheat condition:
If your Air Conditioner (A/C) is on, turn it off.
The A/C system adds heat to the engine
cooling system and turning the A/C off can
help remove this heat.
You can also turn the temperature control to
maximum heat, the mode control to floor and
the blower control to high. This allows the
heater core to act as a supplement to the
radiator and aids in removing heat from the
engine cooling system.
CAUTION!
Accessories plugged into the vehicle power
outlets draw power from the vehicle’s battery,
even when not in use (i.e., cellular devices,
etc.). Eventually, if plugged in long enough
without engine operation, the vehicle’s
battery will discharge sufficiently to degrade
battery life and/or prevent the engine from
starting.
WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam coming
from under the hood, do not open the hood
until the radiator has had time to cool. Never
try to open a cooling system pressure cap
when the radiator or coolant bottle is hot.7

21_VM_OM_EN_USC_t.book Page 207

210IN CASE OF EMERGENCY
NOTE:
Push the ESC OFF switch, to place the Electronic
Stability Control (ESC) system in Partial Off
mode, before rocking the vehicle Ú page 146.
Once the vehicle has been freed, push the ESC
OFF switch again to restore ESC On mode.
WARNING!
Fast spinning tires can be dangerous. Forces
generated by excessive wheel speeds may
cause damage, or even failure, of the axle
and tires. A tire could explode and injure
someone. Do not spin your vehicle's wheels
faster than 30 mph (48 km/h) or for longer than 30 seconds continuously without
stopping when you are stuck and do not let
anyone near a spinning wheel, no matter
what the speed.
CAUTION!
Racing the engine or spinning the wheels may
lead to transmission overheating and failure.
Allow the engine to idle with the transmission
in NEUTRAL for at least one minute after
every five rocking-motion cycles. This will
minimize overheating and reduce the risk of
transmission failure during prolonged efforts
to free a stuck vehicle.
CAUTION!
When “rocking” a stuck vehicle by shifting
between DRIVE and REVERSE, do not spin
the wheels faster than 15 mph (24 km/h), or drivetrain damage may result.
Revving the engine or spinning the wheels
too fast may lead to transmission over -
heating and failure. It can also damage the
tires. Do not spin the wheels above 30 mph
(48 km/h) while in gear (no transmission
shifting occurring).

SERVICING AND MAINTENANCE227
Under normal operating conditions, the
catalytic converter will not require
maintenance. However, it is important to keep
the engine properly tuned to ensure proper
catalyst operation and prevent possible catalyst
damage. NOTE:
Intentional tampering with emissions control
systems can result in civil penalties being
assessed against you.
In unusual situations involving grossly
malfunctioning engine operation, a scorching
odor may suggest severe and abnormal catalyst
overheating. If this occurs, stop the vehicle, turn
off the engine and allow it to cool. Service,
including a tune-up to manufacturer's
specifications, should be obtained immediately.
To minimize the possibility of catalytic converter
damage:
Do not interrupt the ignition when the trans
-
mission is in gear and the vehicle is in
motion.
Do not try to start the vehicle by pushing or
towing the vehicle.
Do not idle the engine with any ignition
components disconnected or removed, such
as when diagnostic testing, or for prolonged
periods during very rough idle or malfunc -
tioning operating conditions.
Cooling System CAUTION!
The catalytic converter requires the use of
unleaded fuel only. Leaded gasoline will
destroy the effectiveness of the catalyst as
an emissions control device and may seri -
ously reduce engine performance and
cause serious damage to the engine.
Damage to the catalytic converter can
result if your vehicle is not kept in proper
operating condition. In the event of engine
malfunction, particularly involving engine
misfire or other apparent loss of perfor -
mance, have your vehicle serviced
promptly. Continued operation of your
vehicle with a severe malfunction could
cause the converter to overheat, resulting
in possible damage to the converter and
vehicle.
WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam
coming from under the hood, do not open
the hood until the radiator has had time to
cool. Never open a cooling system pressure
cap when the radiator or coolant bottle is
hot.
Keep hands, tools, clothing, and jewelry
away from the radiator cooling fan when
the hood is raised. The fan starts automati -
cally and may start at any time, whether the
engine is running or not.
When working near the radiator cooling fan,
disconnect the fan motor lead or turn the
ignition to the OFF mode. The fan is
temperature controlled and can start at any
time the ignition is in the ON mode.
