STARTING
Positions of the ignition
1. LOCK, locks the automatic
transaxle gearshift lever and allows
key removal. This position also shuts
the engine and all electrical
accessories off without locking the
steering wheel. To lock the steering
wheel, remove the key then turn the
steering wheel.
2. ACC, allows the electrical accessories such as the radio to operate
while the engine is not running. This position also unlocks the steering
wheel.
3. RUN, all electrical circuits operational. Warning lights illuminated. Key
position when driving.
4. START, cranks the engine. Release the key as soon as the engine
starts.
Starting your vehicle
Engine starting is controlled by the powertrain control system. This
system meets all Canadian Interference-Causing Equipment standard
requirements regulating the impulse electrical field strength of radio
noise.
When starting a fuel-injected engine, don’t press the accelerator before
or during starting. Only use the accelerator when you have difficulty
starting the engine. For more information on starting the vehicle, refer to
Starting the enginein this chapter.
To avoid potential transmission damage at extremely cold temperatures
(below -20°F [-30°C]), it is recommended that the vehicle be warmed up
to normal operating temperature before driving at highway speeds above
50 mph (80 km/h). Normal operating temperature is normally reached
after 10 minutes of moderate driving or idling.
Extended idling at high engine speeds can produce very high
temperatures in the engine and exhaust system, creating the risk
of fire or other damage.

BRAKES
Occasional brake noise is normal. If a metal-to-metal, continuous grinding
or continuous squeal sound is present, the brake linings may be worn-out
and should be inspected by a qualified service technician. If the vehicle
has continuous vibration or shudder in the steering wheel while braking,
the vehicle should be inspected by a qualified service technician.
Refer toBrake system warning
lightin theInstrument Cluster
chapter for information on the brake
system warning light.
Four-wheel anti-lock brake system (ABS)
Your vehicle is equipped with an Anti-lock Braking System (ABS). This
system helps you maintain steering control during emergency stops by
keeping the brakes from locking. Noise from the ABS pump motor and
brake pedal pulsation may be observed during ABS braking and the
brake pedal may suddenly travel a little farther as soon as ABS braking is
done and normal brake operation resumes. These are normal
characteristics of the ABS and should be no reason for concern.
Using ABS
When hard braking is required, apply continuous force on the brake
pedal; do not pump the brake pedal since this will reduce the
effectiveness of the ABS and will increase your vehicle’s stopping
distance. The ABS will be activated immediately, allowing you to retain
full steering control during hard braking and on slippery surfaces.
However, the ABS does not decrease stopping distance.
ABS warning lamp
The ABS lamp in the instrument
cluster momentarily illuminates
when the ignition is turned on. If
the light does not illuminate during
start up, remains on or flashes, the
ABS is disabled due to a malfunction and needs to be serviced.
Even when the ABS is disabled,
normal braking is still effective. (If
your BRAKE warning lamp
illuminates with the parking brake
released, have your brake system
serviced immediately.)

is especially useful on slippery road surfaces. The system operates by
detecting and controlling wheel spin. The system borrows many of the
electronic elements already present in the anti-lock braking system
(ABS).
Wheel-speed sensors allow excess wheel spin to be detected by the
Traction Control
portion of the ABS computer. Excess wheel spin is
controlled through engine torque reduction. This is realized via the fully
electronic engine control system. This process is very sensitive to driving
conditions and very fast acting. The wheels “search” for optimum
traction several times a second and adjustments are made accordingly.
The Traction Control
system will allow your vehicle to make better use
of available traction on slippery surfaces. The system is a driver aid
which makes your vehicle easier to handle primarily on snow and ice
covered roads.
During Traction Control
operation the engine will not “rev-up” when
you push further on the accelerator. This is normal system behavior.
If you should become stuck in deep
snow or on a very slippery road
surface, try switching the Traction
Control
system off. This may allow
excess wheel spin to “dig” the
vehicle out or enable a successful
“rocking” maneuver.
Aggressive driving in any road conditions can cause you to lose
control of your vehicle increasing the risk of severe personal
injury or property damage. The occurrence of a Traction Control

event is an indication that at least some of the tires have exceeded
their ability to grip the road; this may lead to an increased risk of loss
of vehicle control, vehicle rollover, personal injury and death. If you
experience a severe road event, SLOW DOWN.
STEERING
To prevent damage to the power steering system, never hold the steering
wheel at its furthest turning points (until it stops) for more than a few
seconds when the engine is running.
It is also important to maintain a proper power steering fluid level in the
power steering fluid reservoir:
•Do not operate the vehicle with a low power steering pump fluid level
(below the MIN mark on the reservoir).

3. Locate the white plastic cover at
the front driver side of the gearshift
lever. Locate the screw which
attaches this cover and remove
using a screwdriver. Remove the
cover by tilting forward while
pulling up and out of the gearshift
assembly.
4. Locate the silver button in the driver side front area of the gearshift
assembly. Press and hold the silver button while moving the gearshift
lever out of P (Park) into N (Neutral).
5. Start the vehicle and release the parking brake.
If it is necessary to use the above procedure to move the gearshift lever,
it is possible that a fuse has blown or the vehicle’s brakelamps are not
operating properly. Refer toFuses and relaysin theRoadside
Emergencieschapter.
Do not drive your vehicle until you verify that the brakelamps
are working.
Always set the parking brake fully and make sure the gearshift is
latched in P (Park). Turn the ignition to the LOCK position and
remove the key whenever you leave your vehicle.
If the parking brake is fully released, but the brake warning lamp
remains illuminated, the brakes may not be working properly.
See your dealer or a qualified service technician.
Understanding the gearshift positions of the Continuously Variable
Transaxle (CVT) (if equipped)
The CVT is a fully automatic transaxle that electronically monitors
vehicle system inputs and outputs and driver demands to select the
desired drive ratio. Unlike traditional automatic transmissions/transaxles,
the CVT continually adjusts the optimum overall drive ratio between
engine and drive wheels for all operating conditions.
As traditional automatic transmissions/transaxles shift up or down in
gears, this shifting in gear ratios is noticeable by increasing and
2005 Montego(mgo)
Owners Guide (post-2002-fmt)
USA_English(fus)
Driving
170

decreasing engine RPM which causes a slight energy loss as the gears
change. The gear changes can be felt by the driver.
With the CVT, there is no energy transfer loss from shifting because
there is no gear shifting up or down. Acceleration up to vehicle operating
speed is smooth and continuous; uninterrupted by gear shifting. The
same holds true for coasting down to idle; smooth and continuous.
Unlike traditional automatic transmissions/transaxles, the CVT offers
more responsive performance and increased fuel economy.
P (Park)
This position locks the transaxle and prevents the front wheels from
turning.
To put your vehicle in gear:
•Depress the brake pedal
•Move the gearshift lever into the desired gear
To put your vehicle in P (Park):
•Come to a complete stop
•Move the gearshift lever and securely latch it in P (Park)
Always set the parking brake fully and make sure the gearshift is
latched in P (Park). Turn the ignition to the LOCK position and
remove the key whenever you leave your vehicle.

R (Reverse)
With the gearshift lever in R (Reverse), the vehicle will move backward.
Always come to a complete stop before shifting into and out of R
(Reverse).
N (Neutral)
With the gearshift lever in N (Neutral), the vehicle can be started and is
free to roll. Hold the brake pedal down while in this position.
D (Drive)
The normal driving position for the best fuel economy.
L (Low)
Provides more engine braking when the accelerator pedal is released
than D (Drive).

indicator light on the control will illuminate when the system is turned
off. If the indicator light illuminates when the RSS is not turned off, it
may indicate a failure in the RSS.
Keep the RSS sensors (located on the rear bumper/fascia) free
from snow, ice and large accumulations of dirt (do not clean the
sensors with sharp objects). If the sensors are covered, it will
affect the accuracy of the RSS.
If your vehicle sustains damage to the rear bumper/fascia, leaving
it misaligned or bent, the sensing zone may be altered causing
inaccurate measurement of obstacles or false alarms.
ALL WHEEL DRIVE (AWD) SYSTEM (IF EQUIPPED)
Your vehicle may be equipped with a full-time All Wheel Drive (AWD)
system. With the AWD option, power will be delivered to the front
wheels and distributed to the rear wheels as needed. The AWD system is
active all the time and requires no input from the operator.
All components of the AWD system are sealed for life and require no
maintenance.
If your vehicle is equipped with AWD, a spare tire of a different size
other than the tire provided should never be used. A dissimilar spare tire
size (other than the spare tire provided) or major dissimilar tire sizes
between the front and rear axles could cause the AWD system to stop
functioning and default to front wheel drive.
Note:Your AWD vehicle is not intended for off-road use. The AWD
feature gives your vehicle some limited off-road capabilities in which
driving surfaces are relatively level, obstruction-free and otherwise
similar to normal on-road driving conditions. Operating your vehicle
under other than those conditions could subject the vehicle to excessive
stress which might result in damage which is not covered under your
warranty.
Driving off-highway with AWD vehicles
AWD vehicles are specially equipped for driving on sand, snow, mud and
rough roads and have operating characteristics that are somewhat
different from conventional vehicles, both on and off the highway.
When driving at slow speeds off-highway under high outside
temperatures, use L (Low) gear when possible. L (Low) gear operation
will maximize the engine and transmission cooling capability.
Under severe operating conditions, the A/C may cycle on and off to
protect overheating of the engine.

Basic operating principles
•Drive slower in strong crosswinds which can affect the normal steering
characteristics of your vehicle.
•Be extremely careful when driving on pavement made slippery by
loose sand, water, gravel, snow or ice.
If your vehicle goes off the edge of the pavement
•If your vehicle goes off the edge of the pavement, slow down, but
avoid severe brake application, ease the vehicle back onto the
pavement only after reducing your speed. Do not turn the steering
wheel too sharply while returning to the road surface.
•It may be safer to stay on the apron or shoulder of the road and slow
down gradually before returning to the pavement. You may lose
control if you do not slow down or if you turn the steering wheel too
sharply or abruptly.
•It often may be less risky to strike small objects, such as highway
reflectors, with minor damage to your vehicle rather than attempt a
sudden return to the pavement which could cause the vehicle to slide
sideways out of control or rollover. Remember, your safety and the
safety of others should be your primary concern.
If your vehicle gets stuck
If your vehicle gets stuck in mud or snow it may be rocked out by
shifting between forward and reverse gears, stopping between shifts, in a
steady pattern. Press lightly on the accelerator in each gear.
If your vehicle is equipped with Traction Control
, it may be beneficial
to disengage the Traction Control
system while attempting to rock the
vehicle.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a few minutes or damage
to the transmission and tires may occur or the engine may
overheat.
Always set the parking brake fully and make sure the gearshift is
latched in P (Park). Turn the ignition to the LOCK position and
remove the key whenever you leave your vehicle.

If the parking brake is fully released, but the brake warning lamp
remains illuminated, the brakes may not be working properly.
See your dealer or a qualified service technician.
Do not spin the wheels at over 35 mph (56 km/h). The tires may
fail and injure a passenger or bystander.
Emergency maneuvers
•In an unavoidable emergency situation where a sudden sharp turn
must be made, remember to avoid “over-driving” your vehicle (i.e.,
turn the steering wheel only as rapidly and as far as required to avoid
the emergency). Excessive steering will result in less vehicle control,
not more. Additionally, smooth variations of the accelerator and/or
brake pedal pressure should be utilized if changes in vehicle speed are
called for. Avoid abrupt steering, acceleration or braking which could
result in an increased risk of loss of vehicle control, vehicle rollover
and/or personal injury. Use all available road surface to return the
vehicle to a safe direction of travel.
•In the event of an emergency stop, avoid skidding the tires and do not
attempt any sharp steering wheel movements.
•If the vehicle goes from one type of surface to another (i.e., from
concrete to gravel) there will be a change in the way the vehicle
responds to a maneuver (steering, acceleration or braking). Again,
avoid these abrupt inputs.
AWD Systems (if equipped)
AWD uses all four wheels to power
the vehicle. This increases traction,
enabling you to drive over terrain
and road conditions that a
conventional two-wheel drive vehicle
cannot.
Sand
When driving over sand, try to keep all four wheels on the most solid
area of the trail. Avoid reducing the tire pressures but shift to a lower

gear and drive steadily through the terrain. Apply the accelerator slowly
and avoid spinning the wheels.
If your vehicle is equipped with a 6–speed transmission:When
driving at slow speeds in deep sand under high outside temperatures,
use L (Low) gear when possible. L (Low) gear operation will maximize
the engine and transmission cooling capability.Do not perform this
operation if your vehicle is equipped with an
electronically-controlled CVT.
Under severe operating conditions, the A/C may cycle on and off to
protect overheating of the engine.
Avoid excessive speed because vehicle momentum can work against you
and cause the vehicle to become stuck to the point that assistance may
be required from another vehicle. Remember, you may be able to back
out the way you came if you proceed with caution.
Mud and water
If you must drive through high water, drive slowly. Traction or brake
capability may be limited.
When driving through water, determine the depth; avoid water higher
than the bottom of the hubs (if possible) and proceed slowly. If the
ignition system gets wet, the vehicle may stall.
Once through water, always try the brakes. Wet brakes do not stop the
vehicle as effectively as dry brakes. Drying can be improved by moving
your vehicle slowly while applying light pressure on the brake pedal.
Be cautious of sudden changes in vehicle speed or direction when you
are driving in mud. Even AWD vehicles can lose traction in slick mud. As
when you are driving over sand, apply the accelerator slowly and avoid
spinning your wheels. If the vehicle does slide, steer in the direction of
the slide until you regain control of the vehicle.
If the transmission, AWD system components or axles are submerged in
water, their fluids should be checked and changed, if necessary.
Driving through deep water may damage the transmission.
If the front or rear axle is submerged in water, the axle lubricant and
PTU (Power Transfer Unit) lubricant should be checked and changed if
necessary.
After driving through mud, clean off residue stuck to rotating driveshafts
and tires. Excess mud stuck on tires and rotating driveshafts causes an
imbalance that could damage drive components.
