Intermittent Wiper System
Use the intermittent wiper when weather
conditions make a single wiping cycle with a
variable pause between cycles desirable.
Rotate the end of the multifunction lever to the
first detent position, and then turn the end of
the lever to select the desired delay interval.
There are five delay settings, which allow you to
regulate the wipe interval from a minimum of
one cycle every second to a maximum of
approximately 36 seconds between cycles. The
delay intervals will double in duration when the
vehicle speed is 10 mph (16 km/h) or less.
Windshield Washers
To use the windshield washer, push on the end
of the lever to the second detent and hold while
spray is desired. If the lever is pushed while on
the intermittent setting, the wipers will turn on
and operate for several wipe cycles after the
lever is released, and then resume the
intermittent interval previously selected. If the
lever is pushed while the wipers are in the off
position, the wipers will operate several wipe
cycles, then turn off.
Mist Feature
Push the end of the multifunction lever inward
(toward the steering column) to the first detent
and release for a single wiping cycle.
NOTE:
The mist feature does not activate the washer
pump; therefore, no washer fluid will be sprayed
on the windshield. The wash function must be
used in order to spray the windshield with
washer fluid.
Rear Wiper And Washer
Rotating the center ring of the wiper lever to the
first detent activates the rear intermittent
wipers. To activate the washers, rotate the
center ring fully forward and the washers will
spray until the ring is released, and then
resume the intermittent interval.
NOTE:
Rear window wipers function in the intermittent
wiper speed only.

ATC display will be turned off when the system
is being used in the manual mode.
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.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for proper coolant selection.
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. Refer to “Fluids And
Lubricants” in “Technical Specifications” for
proper coolant selection. Use of the air Recircu -
lation mode during Winter months is not
recommended, because it may cause window
fogging.
Vacation/Storage
Before 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.

190STARTING AND OPERATING
Automatic Transmission
The DRIVE range can be selected when towing.
However, if frequent shifting occurs while in
DRIVE, use the Electronic Range Select (ERS)
shift control to manually select a lower gear
range.
NOTE:
Using a lower gear range while operating the
vehicle under heavy loading conditions, will
improve performance and extend transmission
life by reducing excessive shifting and heat
buildup. This action will also provide better
engine braking.
If you REGULARLY tow a trailer for more than
45 minutes of continuous operation, then
change the transmission fluid and filter as
specified for "police, taxi, fleet, or frequent
trailer towing." Refer to the “Maintenance Plan”
for the proper maintenance intervals. Electronic Range Select (ERS)When using the ERS shift control, select the
highest gear that allows for adequate perfor
-
mance and avoids frequent downshifts. For
example, choose “4” if the desired speed can
be maintained. Choose “3” or “2” if needed
to maintain the desired speed.
To prevent excess heat generation, avoid
continuous driving at high RPM. Reduce
vehicle speed as necessary to avoid
extended driving at high RPM. Return to a
higher gear range or vehicle speed when
grade and road conditions allow.
Speed Control — If Equipped
Do not use on hilly terrain or with heavy
loads.
When using the Speed Control, if you experi -
ence speed drops greater than 10 mph
(16 km/h), disengage until you can get back
to cruising speed.
Use Speed Control in flat terrain and with
light loads to maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission
overheating, take the following actions:
City Driving
In city traffic — while stopped, place the trans -
mission in NEUTRAL, but do not increase
engine idle speed.
Highway Driving
Reduce speed.
Temporarily turn off air conditioning.

242SERVICING AND MAINTENANCE
Disposal Of Used Coolant
Used ethylene glycol-based coolant (antifreeze)
is a regulated substance requiring proper
disposal. Check with your local authorities to
determine the disposal rules for your
community. To prevent ingestion by animals or
children, do not store ethylene glycol-based
coolant in open containers or allow it to remain
in puddles on the ground. If ingested by a child
or pet, seek emergency assistance
immediately. Clean up any ground spills
immediately.
Points To Remember
NOTE:
When the vehicle is stopped after a few miles/
kilometers of operation, you may observe vapor
coming from the front of the engine
compartment. This is normally a result of
moisture from rain, snow, or high humidity
accumulating on the radiator and being
vaporized when the thermostat opens, allowing
hot engine coolant (antifreeze) to enter the
radiator. If an examination of your engine compartment
shows no evidence of radiator or hose leaks,
the vehicle may be safely driven. The vapor will
soon dissipate.
Do not overfill the coolant expansion bottle.
Check the coolant freeze point in the radiator
and in the coolant expansion bottle. If engine
coolant (antifreeze) needs to be added, the
contents of the coolant expansion bottle
must also be protected against freezing.
If frequent engine coolant (antifreeze) addi-
tions are required, the cooling system should
be pressure tested for leaks.
Maintain engine coolant (antifreeze) concen
-
tration at a minimum of 50% OAT coolant
(conforming to MS.90032) and distilled
water for proper corrosion protection of your
engine which contains aluminum
components.
Make sure that the coolant expansion bottle
overflow hoses are not kinked or obstructed.
Keep the front of the radiator clean. If your
vehicle is equipped with air conditioning,
keep the front of the condenser clean.
Do not change the thermostat for Summer or
Winter operation. If replacement is ever
necessary, install ONLY the correct type ther -
mostat. Other designs may result in unsatis -
factory engine coolant (antifreeze)
performance, poor gas mileage, and
increased emissions.
Brake System
In order to ensure brake system performance,
all brake system components should be
inspected periodically. Refer to the
“Maintenance Plan” in this section for the
proper maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure
and possibly a collision. Driving with your foot
resting or riding on the brake pedal can result
in abnormally high brake temperatures,
excessive lining wear, and possible brake
damage. You would not have your full braking
capacity in an emergency.
