feature. Refer to the “Customer Programmable Fea-
tures — Uconnect System Settings” in this section of
the manual.
To provide you with maximum comfort in the Automatic
mode during cold start-ups, the blower fan will remain
on low until the engine warms up. The blower will
increase in speed and transition into Auto mode.
Recirculation Control
When outside air contains smoke, odors, or high humid-
ity, or if rapid cooling is desired, you may wish to
recirculate interior air by pressing the RECIRCULATION
control button. Recirculation mode should only be used
temporarily. The recirculation LED will illuminate on the
blower control knob when this button is selected. Push
the button a second time to turn off the Recirculation
mode LED and allow outside air into the vehicle. NOTE:
In cold weather, use of Recirculation mode may
lead to excessive window fogging. The Recirculation
mode is not allowed in Defrost mode to improve window
clearing operation. Recirculation will be disabled auto-
matically if these modes are selected.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corro-
sion protection and to protect against engine overheating.
OAT coolant (conforming to MS.90032) is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is function-
ing properly and the proper amount, type, and concen-
tration of coolant is used. Refer to “Maintenance
Procedures” in “Maintaining Your Vehicle” for proper
212 UNDERSTANDING YOUR INSTRUMENT PANEL

coolant selection. 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 in high. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.
Window Fogging and Frosting
Vehicle windows tend to fog on the inside of the glass in
mild, rainy and/or humid weather. Windows may frost
on the inside of the glass in very cold 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.NOTE:
Automatic Temperature Controls (ATC) will au-
tomatically adjust the climate control settings to reduce
or eliminate window fogging on the front windshield.
When this occurs, recirculation will be unavailable.
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, can cause
odor, and if they enter the plenum they could plug the
water drains. In winter months, ensure the air intake is
clear of ice, slush and snow.4

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust the
inside and outside mirrors, fasten your seat belt, and if
present, instruct any other occupant to buckle their seat
belt.
WARNING!
Never leave children alone in a vehicle. Leaving
unattended children in a vehicle is dangerous for a
number of reasons. A child or others could be seri-
ously or fatally injured. Do not leave the Key Fob in
or near the vehicle (or in a location accessible to
children), and do not leave the ignition of a vehicle
equipped with Keyless Enter-N-Go in the ACC or
ON/RUN mode. A child could operate power win-
dows, other controls, or move the vehicle.
CAUTION!
•Long periods of engine idling, especially at higher
than normal engine idle speeds, can cause exces-
sive exhaust temperatures, which can damage your
vehicle. Do not leave your vehicle unattended with
the engine running.
• Running an engine with a low oil level can cause
severe damage. Check the engine oil level at every
fuel fill-up.
Normal Starting
CAUTION!
The engine in your vehicle is designed for operation
down to 0°F (-18°C). Starting the engine below 0°F
(-18°C) coolant temperature creates a potential for
(Continued)
238 STARTING AND OPERATING

coolant is higher than 107°F (42°C), and vehicle speed is
greater than 16 mph (26 km/h) but less than 18 mph
(29 km/h), and engine speed is less than 1,550 RPM, and
the transmission is in first gear, and the accelerator is at
20% throttle or less. The “Skip Shift Indicator Light”
located in the tachometer will illuminate during these
times.
When the “Skip Shift Indicator Light” illuminates, the
shift mechanism will only allow shifts from first gear to
fourth gear. After you shift the transmission into fourth
gear, you can press the clutch in and shift to another
forward gear.
Downshifting - Proper downshifting will improve fuel
economy and prolong engine life.
To maintain a safe speed and prolong brake life, down-
shift to maintain a safe speed when descending a steep
grade.CAUTION!
If you skip more than one gear while downshifting
or downshift at too high a vehicle speed, you could
damage the engine, transmission, or clutch.
WARNING!
Skipping more than one gear while downshifting,
could cause you to lose control of your vehicle. You
could have a collision.
STREET/RACE MODE — IF EQUIPPED
This vehicle is equipped with a two mode electronic
controlled damping system. This system allows for a
compliant street suspension damping setting or a firmer
race suspension damping setting. When in street mode

•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.
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.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure
that the wheel is properly mounted to the vehicle. Any
time a wheel has been removed and reinstalled on the
vehicle the lug nuts/bolts should be torqued using a
properly calibrated torque wrench.

NOTE:Life expectancy of wiper blades varies depending
on geographical area and frequency of use. Poor perfor-
mance of blades may be present with chattering, marks,
water lines or wet spots. If any of these conditions are
present, clean the wiper blades or replace as necessary.
Adding Washer Fluid
The windshield washer fluid reservoir is located in the
front of the engine compartment on the passenger side of
the vehicle. Be sure to check the fluid level in the
reservoir at regular intervals. Fill the reservoir with
windshield washer solvent (not engine coolant (anti-
freeze) and operate the system for a few seconds to flush
out the residual water.
WARNING!
Commercially available windshield washer solvents
are flammable. They could ignite and burn you. Care
must be exercised when filling or working around
the washer solution.
Exhaust System
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
If you notice a change in the sound of the exhaust system;
or if the exhaust fumes can be detected inside the vehicle;
or when the underside or rear of the vehicle is damaged;
have an authorized technician inspect the complete ex-
haust system and adjacent body areas for broken, dam-
aged, deteriorated, or mispositioned parts. Open seams
or loose connections could permit exhaust fumes to seep
into the passenger compartment. In addition, have the

Cooling System
WARNING!
•When working near the radiator cooling fan, dis-
connect the fan motor lead or cycle the ignition
switch to the LOCK position. The fan is tempera-
ture controlled and can start at any time the igni-
tion switch is in the ON position.
• 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 is hot.
Coolant Checks
Check engine coolant (antifreeze) protection every 12
months (before the onset of freezing weather, where applicable). If the engine coolant (antifreeze) is dirty, the
system should be drained, flushed, and refilled with
fresh OAT coolant (conforming to MS.90032) by an
authorized dealer. Check the front of the A/C
condenser/radiator for any accumulation of bugs, leaves,
etc. If dirty, clean by gently spraying water from a garden
hose vertically down the face of the condenser/radiator.
Check the coolant recovery bottle tubing for brittle rub-
ber, cracking, tears, cuts, and tightness of the connection
at the bottle and radiator. Inspect the entire system for
leaks.
With the engine at normal operating temperature (but
not running), check the cooling system pressure cap for
proper vacuum sealing by draining a small amount of
engine coolant (antifreeze) from the radiator drain cock.
If the cap is sealing properly, the engine coolant (anti-
freeze) will begin to drain from the coolant recovery
