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 a service center if your
vehicle overheats. If you decide to look under the
hood yourself, see Section 7 of this manual. Follow
the warnings under the Cooling System Pressure
Cap paragraph.
17. Washer Fluid Light
This light turns on when the washer fluid level
falls below approximately 1/4 filled. The light will
remain on until fluid is added.
18. Transmission Range Indicator
This display indicator shows the automatic transaxle gear
selection. NOTE: You must apply the brakes before shifting from
Park.
19. Oil Pressure Warning Light
This light shows low engine oil pressure. The light
should turn on momentarily when the engine is
started. If the light turns on while driving, stop the
vehicle and shut off the engine as soon as possible. A
chime will sound for 4 minutes when this light turns on.
Do not operate the vehicle until the cause is corrected.
This light does not show how much oil is in the engine.
The engine oil level must be checked under the hood.
20. High Beam Light
This light shows that the headlights are on high
beam. Pull the turn signal lever towards the
steering wheel to switch the headlights from high or low
beam. UNDERSTANDING YOUR INSTRUMENT PANEL 217

21. Malfunction Indicator Light
This light is part of an onboard diagnostic system
called OBD that monitors engine and automatic
transmission control systems. The light will illu-
minate when the key is in the ON position before engine
start. If the bulb does not come when turning the key
from OFF to ON, have the condition checked promptly.
Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc. may illuminate the light after
engine start. The vehicle should be serviced if the light
stays on through several of your typical driving cycles. In
most situations the vehicle will drive normally and will
not require towing.
The Malfunction Indicator Light flashes to alert to serious
conditions that could lead to immediate loss of power or
severe catalytic converter damage. The vehicle should be
serviced as soon as possible if this occurs. 22. Trac Off Indicator — If Equipped
This display indicator should illuminate for approxi-
mately four seconds as a bulb check when the ignition
switch is first turned ON.
The “TRAC OFF” Indicator will flash if the traction
control is in use.
The “TRAC OFF” Indicator will illuminate if:
• The Traction Control switch has been used to turn
the system OFF.
• There is a Traction Control System malfunction
• The system has been deactivated to prevent damage
to the brake system due to overheated brake tem-
peratures.
NOTE: Extended heavy use of Traction Control may
cause the system to deactivate and turn on the TRAC and
the OFF indicators located in the instrument cluster.218 UNDERSTANDING YOUR INSTRUMENT PANEL

Automatic Transmission
The gear selector must be in the NEUTRAL or PARK
position before you can start the engine. Depress the
brake pedal before shifting into any driving gear.
Normal Starting (Above 32°F / 0°C)
1. Do not depress the accelerator.
2. Turn and hold the ignition key in the START position
and release when engine starts.
3. If engine does not start after 3 seconds, depress the
accelerator lightly (while still cranking the engine).
4. If engine does not start after 15 seconds, turn the
ignition key off.
5. Wait 10 to 15 seconds, and repeat step s1—5.
NOTE: This vehicle is equipped with a transmission
shift interlocking system. The brake pedal must be
depressed to shift out of Park (P). Extremely Cold Weather Starting (Below
20°F /
–29°C)
Follow the same instructions in the “Normal Starting”
procedure.
To insure reliable starting at these temperatures, use of an
externally powered electric engine block heater (available
from your dealer) is recommended.
High Altitude Starting (Above 4,000 ft. / 1 219 m)
Follow the same instructions in the “Normal Starting”
procedure.
To insure reliable starting at these temperatures, use of an
externally powered electric engine block heater (available
from your dealer) is recommended.312 STARTING AND OPERATING

ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms engine coolant and
permits quicker starts in cold weather. Connect the cord
to a standard 110-115 volt AC electrical outlet with a
grounded, three-wire extension cord.
The engine block heater cord is routed under the hood on
the driver side of the vehicle. It has a removable cap that
is located on the driver side of the Integrated Power
Module.
WARNING!Remember to disconnect the cord before driving.
Damage to the 110-115 volt electrical cord could
cause electrocution. AUTOMATIC TRANSMISSION
CAUTION!Damage to the transmission may occur if the follow-
ing precautions are not observed:

WARNING!It is dangerous to shift the selector lever out of “P” or
“N” if the engine speed is higher than idle speed. If
your foot is not firmly on the brake pedal, the
vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when
the engine is idling normally and when your right
foot is firmly on the brake pedal.
Brake/Transmission Interlock System
This system prevents you from moving the gear shift out
of Park and into any gear unless the brake pedal is
pressed. This system is active only while the ignition
switch is in the ON position. Always depress the brake
pedal first, before moving the gear selector out of PARK. Automatic Transmission Ignition Interlock System
This system prevents the key from being removed unless
the shift lever is in PARK. It also prevents shifting out of
PARK unless the key is in the OFF or ON positions.
NOTE: If a malfunction occurs, the system will trap the
key in the ignition cylinder to warn you that this safety
feature is inoperable. The engine can be started and
stopped but the key cannot be removed until you obtain
service.
Four Speed Automatic Transmission
The electronically controlled transmission provides a
precise shift schedule. The transmission electronics are
self-calibrating; therefore, the first few shifts on a new
vehicle, may be somewhat abrupt. This is a normal
condition, and precision shifts will develop within a few
hundred miles.316 STARTING AND OPERATING

Reset Mode - Electronic Transmission
The transmission is monitored electronically for abnor-
mal conditions. If a condition is detected that could cause
damage, the transmission automatically shifts into sec-
ond gear. The transmission remains in second gear
despite the forward gear selected. Park (P), Reverse (R),
and Neutral (N) will continue to operate. This Reset
feature allows the vehicle to be driven to a dealer for
service without damaging the transmission.
In the event that the problem has been momentary, the
transmission can be reset to regain all forward gears.

WARNING!Never use Park position on an automatic transmis-
sion as a substitute for the parking brake. Always
apply parking brake fully when parked to guard
against vehicle movement and possible injury or
damage.
“R” Reverse
Shift into this range only after the vehicle has come to a
complete stop.
“N” Neutral
Engine may be started in this range.
“D” Overdrive
For most city and highway driving, it provides smoothest
upshifts and downshifts and best fuel economy. When
frequent transmission shifting occurs while using the
“D” Overdrive position, such as when operating the vehicle under heavy loading conditions, (i.e. in hilly
terrain, traveling into strong head winds or while towing
heavy trailers), using the “3” position will improve
performance and extend transmission life by reducing
excessive shifting and heat build-up.
“3” Drive
This range eliminates shifts into Overdrive. The transmis-
sion will operate normally in First, Second and Third
while in this range. The “3” position should also be used
when descending steep grades to prevent brake system
distress.
NOTE: Using the “3” range while operating the vehicle
under heavy operating conditions will improve perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat build up.
“L” Low
This range should be used for engine braking when
descending very steep grades. In this range, upshifts will318 STARTING AND OPERATING
