Torque Lock (Automatic Transmission)
If you are parking on a hill and you do not shift your
transmission into P (Park) properly, the weight of
the vehicle may put too much force on the parking pawl
in the transmission. You may nd it difficult to pull the
shift lever out of P (Park). This is called “torque lock.”
To prevent torque lock, set the parking brake and
then shift into P (Park) properly before you leave the
driver seat. To nd out how, seeShifting Into Park
(Automatic Transmission) on page 2-29.
When you are ready to drive, move the shift lever out
of P (Park) before you release the parking brake.
If torque lock does occur, you may need to have
another vehicle push yours a little uphill to take
some of the pressure from the parking pawl in the
transmission, so you can pull the shift lever out
of P (Park).
Shifting Out of Park
Vehicles with an automatic transmission have a shift
interlock system. You have to apply the brake pedal
before you can shift from P (Park) when the ignition is
in the ON/RUN position. SeeAutomatic Transmission
Operation on page 2-22.
If you cannot shift out of P (Park) while holding the
brake pedal down, try this:
1. Set the parking brake.
2. Turn the ignition off and remove the key.
3. Remove the hole cover from the shift lock slot by
prying it off using a small, at object. The shift
lock release slot is located at the top of the
shift lever.

4. Insert the key into the shift lock slot and press and
hold the key.
5. Shift to N (Neutral).
6. Remove the key from the slot, insert the key into
the ignition and start the engine.
7. Replace the shift-lock release slot cover.
8. Apply and hold the brake pedal fully and release
the parking brake.
9. Shift to the gear you want.
10. Have the vehicle xed as soon as you can.
Parking the Vehicle
(Manual Transmission)
Before leaving the vehicle, do the following:
1. Hold the brake pedal down and rmly apply the
parking brake.
2. Fully press in the clutch pedal and place the
shift lever into the gear position as stated below:
When parking on level ground, place the
shift lever into N (Neutral).
When parking downhill, place the shift lever
in R (Reverse).
When parking uphill, place the shift lever in
1 (First).
3. After shifting, turn the ignition to LOCK/OFF,
remove the key and release the clutch.

Running the Vehicle While Parked
It is better not to park with the engine running. But if you
ever have to, here are some things to know.
{CAUTION:
Idling a vehicle in an enclosed area with poor
ventilation is dangerous. Engine exhaust may
enter the vehicle. Engine exhaust contains Carbon
Monoxide (CO) which cannot be seen or smelled.
It can cause unconsciousness and even death.
Never run the engine in an enclosed area that has
no fresh air ventilation. For more information,
seeEngine Exhaust on page 2-32.
{CAUTION:
It can be dangerous to get out of the vehicle if
the automatic transmission shift lever is not fully
in P (Park) with the parking brake rmly set.
The vehicle can roll. Do not leave the vehicle
when the engine is running unless you have to.
If you have left the engine running, the vehicle can
move suddenly. You or others could be injured.
To be sure the vehicle will not move, even when it
is on fairly level ground, always set the parking
brake and move the automatic transmission shift
lever to P (Park), or the manual transmission shift
lever to Neutral.
Follow the proper steps to be sure the vehicle will not
move. If the vehicle has an automatic transmission,
seeShifting Into Park (Automatic Transmission)
on page 2-29.

Rear Window Wiper/Washer
{CAUTION:
In freezing weather, do not use your washer until
the windshield is warmed. Otherwise the washer
uid can form ice on the windshield, blocking your
vision.
The vehicle may have a rear window wiper/washer.
Turn the rear wiper/washer band to operate the
rear window wiper/washer.
OFF:Turns the rear window wiper/washer off.
Z:Turns the rear wiper on for intermittent wipes.
Y:Sprays washer uid onto the rear window and the
wiper operates continuously.
The windshield washer reservoir is used for the
windshield and rear window. Check the uid level if
either washer is not working. SeeWindshield Washer
Fluid on page 5-33.
Cruise Control
For vehicles with cruise control, a speed of about
24 mph (39 km/h) or more can be maintained without
keeping your foot on the accelerator. Cruise control does
not work at speeds below 24 mph (39 km/h).
When the brakes are applied, or the clutch pedal if you
have a manual transmission, the cruise control turns off.
{CAUTION:
Cruise control can be dangerous where you cannot
drive safely at a steady speed. So, do not use the
cruise control on winding roads or in heavy traffic.
Cruise control can be dangerous on slippery roads.
On such roads, fast changes in tire traction can
cause excessive wheel slip, and you could lose
control. Do not use cruise control on slippery roads.
3-10

Resuming a Set Speed
If the cruise control is set to a desired speed and then
the brakes are applied, or the clutch pedal if you have
a manual transmission, the cruise control shuts off.
But it does not need to be reset.
Once the vehicle is going about 24 mph (39 km/h) or
more, briey press the RES+ button. The vehicle returns
to the previously set speed and stays there.
If the RES+ button is held, the vehicle speed will
continue to increase until the button is released or the
brake pedal is applied. Do not hold in the RES+ button,
unless you want the vehicle to go faster.
Increasing Speed While Using Cruise
Control
There are two ways to go to a higher speed.
Use the accelerator pedal to get to a higher speed.
Press the SET−button, then release the button and
the accelerator pedal.
Press the RES+ button. Hold it there until the
desired speed is reached, and then release it.
To increase the vehicle speed in small amounts,
briey press the RES+ button and then release it.
Each time this is done, the vehicle goes about
1 mph (1.6 km/h) faster.The accelerate feature only works after the cruise
control is turned on by pressing the SET−button.
Reducing Speed While Using Cruise
Control
There are two ways to reduce the vehicle speed while
using cruise control:
Press the SET−button until the lower speed
desired is reached, then release it.
To slow down in small amounts, briey press the
SET−button. Each time this is done, the vehicle
goes about 1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase the vehicle speed.
When you take your foot off the pedal, the vehicle
slows down to the cruise control speed set earlier.
3-12

Using Cruise Control on Hills
How well the cruise control works on hills depends upon
the vehicle speed, load, and the steepness of the
hills. When going up steep hills, you might have to step
on the accelerator pedal to maintain the vehicle’s
speed. When going downhill, you might have to brake
or shift to a lower gear to keep the vehicle’s speed
down. When the brakes are applied the cruise control
turns off.
Ending Cruise Control
There are two ways to turn off the cruise control:
Step lightly on the brake pedal, or press the clutch
pedal, if you have a manual transmission.
PressI/Oon the cruise control pad.
Erasing Speed Memory
The cruise control set speed memory is erased when
the cruise control or the ignition is turned off.
Exterior Lamps
The lever on the left side of the steering column
operates the exterior lamps.
The exterior lamp band has three positions:

Charging System Light
This light will come on briey when the ignition is turned
on, and the engine is not running, as a check to show
it is working.
It should go out when the engine is started. If it stays
on, or comes on while driving, there may have a problem
with the electrical charging system. Have it checked
by your dealer/retailer. Driving while this light is on could
drain the battery. If a short distance must be driven
with the light on, turn off all accessories, such as
the radio and air conditioner to help reduce the drain
on the battery.
Up-Shift Light
The vehicle may have an
up-shift light.
When this light comes on, shift to the next higher gear if
weather, road, and traffic conditions allow.
SeeManual Transmission Operation on page 2-26for
more information.
Brake System Warning Light
The vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part can
still work and stop the vehicle. For good braking,
both parts need to work.

Antilock Brake System (ABS)
Warning Light
For vehicles with the
Antilock Brake System
(ABS), this light comes on
briey when the engine
is started.
If the light stays on, turn the ignition to LOCK/OFF or if
the light comes on, stop as soon as possible and
turn the ignition off. Then start the engine again to reset
the system. If the light still stays on, or comes on
again while driving, the vehicle needs service. See your
dealer/retailer. If the regular brake system warning
light is not on, the brakes will still work, but the antilock
brakes will not work. If the regular brake system
warning light is also on, the antilock brakes will not
work and there is a problem with the regular brakes.
SeeBrake System Warning Light on page 3-28.The ABS warning light will come on briey when the
ignition is turned to ON/RUN. This is normal. If the light
does not come on then, have it xed so it will be
ready to warn if there is a problem.
Hold Mode Light
If the vehicle has this
feature, this light comes on
when the hold mode is
active.
If the HOLD mode light ashes, have the vehicle
checked. See “Hold Mode” underAutomatic
Transmission Operation on page 2-22for more
information.

Malfunction Indicator Lamp
Check Engine Light
A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation of
the fuel, ignition, and emission control systems. It makes
sure that emissions are at acceptable levels for the life of
the vehicle, helping to produce a cleaner environment.
This light comes on when
the ignition is on, but the
engine is not running, as a
check to show it is
working. If it does not,
have the vehicle serviced
by your dealer/retailer.
If the check engine light comes on and stays on, while
the engine is running, this indicates that there is an
OBD II problem and service is required.
Malfunctions often are indicated by the system before
any problem is apparent. Heeding the light can prevent
more serious damage to the vehicle. This system
assists the service technician in correctly diagnosing
any malfunction.Notice:If the vehicle is continually driven with
this light on, after a while, the emission controls
might not work as well, the vehicle’s fuel economy
might not be as good, and the engine might not
run as smoothly. This could lead to costly repairs
that might not be covered by the vehicle warranty.
Notice:Modications made to the engine,
transmission, exhaust, intake, or fuel system of the
vehicle or the replacement of the original tires
with other than those of the same Tire Performance
Criteria (TPC) can affect the vehicle’s emission
controls and can cause this light to come on.
Modications to these systems could lead to
costly repairs not covered by the vehicle warranty.
This could also result in a failure to pass a
required Emission Inspection/Maintenance test.
SeeAccessories and Modifications on page 5-3.
This light comes on during a malfunction in one of
two ways:
Light Flashing:A misre condition has been detected.
A misre increases vehicle emissions and could
damage the emission control system on the vehicle.
Diagnosis and service might be required.
