Speedometer:Indicates the
current vehicle speed.
Engine coolant temperature
gauge:Indicates engine coolant
temperature. At normal operating
temperature, the needle will be in
the normal range.If it enters the
red section, the engine is
overheating. Stop the vehicle as
soon as safely possible, switch
off the engine and let the engine cool.If it enters the red section
and theservice engine soonindicator light illuminates, refer toHow
fail safe cooling worksin theMaintenance and Specificationschapter.
WARNING:Never remove the coolant reservoir cap while the
engine is running or hot.

Passenger heated seat control (if equipped):Press to
activate/deactivate the passenger heated seat. SeeHeated seatsin the

11.
Recirculated air:Press to activate/deactivate air recirculation
in the vehicle. Recirculated air may reduce the amount of time needed to
cool down the interior of the vehicle and may also help reduce undesired
odors from reaching the interior of the vehicle. Recirculated air engages
automatically when MAX A/C is selected or can be engaged manually in
any airflow mode except
(defrost). When the ignition switch is
turned off and back on, the climate system will return to the recirculated
air mode only if the A/C button LED is illuminated and the air
distribution selection is either
(panel) or(panel/floor).
12.MAX A/C:Distributes recirculated air through the instrument panel
vents to cool the vehicle. This re-cooling of the interior air is more
economical and efficient. Recirculated air may also help reduce
undesirable odors from entering the vehicle. Press the MAX A/C button
again for normal A/C operation.
13.A/C:Press to activate/deactivate air conditioning. Use with
recirculated air to improve cooling performance and efficiency. A/C
engages automatically in MAX A/C,
(defrost) and
(floor/defrost).

Operating tips
•To reduce fog build-up on the windshield during humid weather,
select
(defrost) or(floor/defrost).
•To reduce humidity build-up inside the vehicle, do not drive with the
system off or with
(recirculated air) engaged and A/C off.
•Do not put objects under the front seats that will interfere with the
airflow to the back seats.
•Remove any snow, ice or leaves from the air intake area at the base of
the windshield.
•To improve the time to reach comfort in hot weather, drive with the
windows slightly open for 2-3 minutes after start up or until the
vehicle has been “aired out.”
•A small amount of air may be felt from the floor vent regardless of the
air distribution setting that is selected.
During extreme high ambient temperatures when idling stationary for
extended periods of time in gear, it is recommended to run the A/C in
the MAX A/C position, reduce blower fan speed from the highest setting
and put the vehicle’s transmission into the P (Park) gear position
(automatic transmission only) to continue to receive cool air from your
A/C system.
For maximum cooling performance in MAX A/C mode:
1. Select MAX A/C.
2. Select the coolest temperature setting.
3. Set the fan to the highest speed initially. As the interior starts to cool
down, adjust the fan speed to maintain comfort.
To aid in side window defogging/demisting in cold weather:
1. Select
.
2. Select A/C.
3. Adjust the temperature control to maintain comfort.
4. Set the fan speed to the highest setting.
5. Direct the outer instrument panel vents towards the side windows.
To increase airflow to the outer instrument panel vents, close the vents
located in the middle of the instrument panel.

JUMP STARTING
WARNING:The gases around the battery can explode if
exposed to flames, sparks, or lit cigarettes. An explosion could
result in injury or vehicle damage.
WARNING:Batteries contain sulfuric acid which can burn skin,
eyes and clothing, if contacted.
Do not attempt to push-start your automatic transmission
vehicle. Automatic transmissions do not have push-start
capability. Attempting to push-start a vehicle with an automatic
transmission may cause transmission damage.
Preparing your vehicle
When the battery is disconnected or a new battery is installed, the
automatic transmission must relearn its shift strategy. As a result, the
transmission may have firm and/or soft shifts. This operation is
considered normal and will not affect function or durability of the
transmission. Over time, the adaptive learning process will fully update
transmission operation.
1.Use only a 12–volt supply to start your vehicle.
2. Do not disconnect the battery of the disabled vehicle as this could
damage the vehicle’s electrical system.
3. Park the booster vehicle close to the hood of the disabled vehicle
making sure the two vehiclesdo nottouch. Set the parking brake on
both vehicles and stay clear of the engine cooling fan and other moving
parts.
4. Check all battery terminals and remove any excessive corrosion before
you attach the battery cables. Ensure that vent caps are tight and level.
5. Turn the heater fan on in both vehicles to protect from any electrical
surges. Turn all other accessories off.

When the engine is cold, check the
level of the engine coolant in the
reservoir.
•The engine coolant should be at the FULL COLD level, or within the
COLD FILL or MIN / MAX range as listed on the engine coolant
reservoir (depending upon application).
•Refer toscheduled maintenance informationfor service interval
schedules.
If the engine coolant has not been checked at the recommended interval,
the engine coolant reservoir may become low or empty. If the reservoir is
low or empty, add engine coolant to the reservoir. Refer toAdding
engine coolantin this chapter.
Note:Automotive fluids are not interchangeable; do not use engine
coolant/antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
Adding engine coolant
When adding coolant, make sure it is a 50/50 mixture of engine coolant
and distilled water. Add the mixture to the coolant reservoir,when the
engine is cool,until the appropriate fill level is obtained. If coolant is
filled to the COLD FILL RANGE or FULL COLD level when the engine is
not cool, the system will remain underfilled.
WARNING:Do not add engine coolant when the engine is hot.
Steam and scalding liquids released from a hot cooling system
can burn you badly. Also, you can be burned if you spill coolant on hot
engine parts.
WARNING:Do not put engine coolant in the windshield washer
fluid container. If sprayed on the windshield, engine coolant
could make it difficult to see through the windshield.
•DO NOT MIXdifferent colors or types of coolant in your vehicle.
Make sure the correct coolant is used.DO NOT MIXrecycled coolant

and new (unused) coolant together in the vehicle. Mixing of engine
coolants may harm your engine’s cooling system. The use of an
improper coolant may harm engine and cooling system components
and may void the warranty. Refer toMaintenance product
specifications and capacitiesin this chapter.
•A large amount of water without engine coolant may be added, in case
of emergency, to reach a vehicle service location. In this instance, the
cooling system must be drained and refilled with a 50/50 mixture of
engine coolant and distilled water as soon as possible. Water alone
(without engine coolant) can cause engine damage from corrosion,
overheating or freezing.
•Do not use alcohol, methanol, brine or any engine coolants
mixed with alcohol or methanol antifreeze (coolant).Alcohol
and other liquids can cause engine damage from overheating or
freezing.
•Do not add extra inhibitors or additives to the coolant.These
can be harmful and compromise the corrosion protection of the engine
coolant.
For vehicles with overflow coolant systems with a non-pressurized cap
on the coolant recovery system, add coolant to the coolant recovery
reservoir when the engine is cool. Add the proper mixture of coolant and
distilled water to the FULL COLD level. For all other vehicles which have
a coolant degas system with a pressurized cap, or if it is necessary to
remove the coolant pressure relief cap on the radiator of a vehicle with
an overflow system, follow these steps to add engine coolant.
WARNING:To reduce the risk of personal injury, make sure the
engine is cool before unscrewing the coolant pressure relief cap.
The cooling system is under pressure; steam and hot liquid can come
out forcefully when the cap is loosened slightly.
Add the proper mixture of coolant and water to the cooling system by
following these steps:
1. Before you begin, turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the coolant
pressure relief cap on the coolant reservoir (a translucent plastic bottle).
Slowly turn cap counterclockwise (left) until pressure begins to release.
3. Step back while the pressure releases.
4. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.
