If you smell exhaust fumes inside your vehicle, have your dealer
inspect your vehicle immediately. Do not drive if you smell
exhaust fumes.
Important ventilating information
If the engine is idling while the vehicle is stopped for a long period of
time, open the windows at least 2.5 cm (one inch) or adjust the heating
or air conditioning to bring in fresh air.
BRAKES
Your service brakes are self-adjusting. Refer to the scheduled
maintenance guide for scheduled maintenance.
Occasional brake noise is normal and often does not indicate a
performance concern with the vehicle ’ s brake system. In normal
operation, automotive brake systems may emit occasional or intermittent
squeal or groan noises when the brakes are applied. Such noises are
usually heard during the first few brake applications in the morning;
however, they may be heard at any time while braking and can be
aggravated by environmental conditions such as cold, heat, moisture,
road dust, salt or mud. If a “ metal-to-metal, ”“ continuous grinding ” or
“ continuous squeal ” sound is present while braking, the brake linings
may be worn-out and should be inspected by a qualified service
technician.
If you are driving down a long or steep hill, shift to a lower gear.
Do not apply your brakes continuously, as they may overheat
and become less effective.
Anti-lock brake system (ABS)
On ABS-equipped vehicles, a noise from the hydraulic pump motor and
pulsation in the pedal may be observed during ABS braking events. Pedal
pulsation coupled with noise while braking under panic conditions or on
loose gravel, bumps, wet or snowy roads is normal and indicates proper
functioning of the vehicle ’ s anti-lock brake system. The ABS performs a
self-check after you start the engine and begin to drive away. A brief
mechanical noise may be heard during this test. This is normal. If a
malfunction is found, the ABS warning light will come on. If the vehicle
has continuous vibration or shudder in the steering wheel while braking,
the vehicle should be inspected by a qualified service technician.

The ABS operates by detecting the onset of wheel lockup during brake
applications and compensates for this tendency. The wheels are
prevented from locking even when the brakes are firmly applied.
Using ABS
• In an emergency or when maximum efficiency from the four-wheel
ABS is required, apply continuous force on the brake. The four wheel
ABS will be activated immediately, thus allowing you to retain steering
control of your vehicle and, providing there is sufficient space, will
enable you to avoid obstacles and bring the vehicle to a controlled
stop.
• The anti-lock system does not always reduce stopping distance.
Always leave enough room between your vehicle and the vehicle in
front of you to stop.
• We recommend that you familiarize yourself with this braking
technique. However, avoid taking any unnecessary risks.
ABS warning lamp ABS
The ABS
warning lamp in the instrument cluster momentarily illuminates
when the ignition is turned to the ON position. If the light does not
illuminate momentarily at start up, remains on or continues to flash, the
ABS needs to be serviced.
With the ABS light on, the anti-lock
brake system is disabled and normal
braking is still effective unless the
brake warning light also remains
illuminated with parking brake
released. (If your brake warning lamp illuminates, have your vehicle
serviced immediately.)
Brake Assist (if equipped)
The Brake Assist system provides full braking force during panic braking
situations. It detects a rapid application of the brake pedal and
maximizes the amount of brake booster assist, helping the driver to
achieve maximum braking pressure. Once a panic brake application is
detected, the system will remain activated as long as the brake pedal is
depressed. The system is deactivated by releasing the brake pedal.
When the system activates, the brake pedal will travel with very little
effort; this is normal. P!BRAKE

If the parking brake fails to release
after completing this procedure, use
the manual parking brake release
lever.
Pull the release lever to release the
brake. Driving with the parking
brake on will cause the brakes to
wear out quickly and reduce fuel
economy.
STEERING
Your vehicle is equipped with power steering. Power steering uses energy
from the engine to decrease the driver ’ s effort in steering the vehicle.
To prevent damage to the power steering pump:
• Never hold the steering wheel to the extreme right or the extreme left
for more than a few seconds when the engine is running.
• Do not operate the vehicle with the power steering pump fluid level
below the MIN mark on the reservoir.
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
If the steering wanders or pulls, check for:
• Underinflated tire(s) on any wheel(s)
• Uneven vehicle loading
• High crown in center of road
• High crosswinds
• Wheels out of alignment
• Loose or worn suspension components
Speed sensitive steering
Your vehicle is equipped with speed sensitive, variable assist power
steering (VAPS). At low speeds, steering assist will adjust to reduce
efforts and improve low speed maneuverability and at high speeds, the
assist will adjust to improve steering feel.
If the amount of effort required to steer your vehicle changes while
driving at a constant vehicle speed, have the power steering system
checked by your dealer or a qualified service technician.

AIR SUSPENSION SYSTEM
The air suspension system is designed to improve ride comfort, vehicle
handling and general vehicle performance by adjusting the vehicle ’ s ride
height according to vehicle speed, weight added to or removed from the
vehicle and four-wheel drive (if equipped) operation. Normal vehicle
operation does not require any action by the driver.
When you enter the vehicle and the ignition is off, the air suspension will
have automatically lowered the vehicle to its lowest height to provide
easier entry. When a door or the liftgate is opened, the system
memorizes and maintains that height until either all doors are closed or
the vehicle ’ s speed exceeds 24 km/h (15 mph). The air suspension
system will then raise the vehicle ’ s height to its normal position when the
ignition is turned on, all doors are closed and the transmission is shifted
from P (Park).
When the vehicle is in motion, the air suspension will adjust the vehicle
ride height to normal operating position to maximize your ride comfort.
If your vehicle is equipped with four-wheel drive and you shift into 4WD
LOW, the air suspension will not move to it ’ s lowest position; instead, the
ride height is raised above the normal ride height position (at speeds
below 40 km/h [25 mph]) to improve ground clearance.
If a load is added to, or removed from the vehicle, the load leveling
feature of the air suspension system will adjust the suspension to keep
the vehicle at a constant level.
When exiting the vehicle, the air suspension will automatically lower the
vehicle to its lowest height to provide easier exit. You may hear a buzz or
click from the air suspension system when the ignition is turned off. The
air suspension system will stay active for 40 minutes after the ignition is
turned off to accommodate any load changes. (The air compressor may
run when the vehicle is off; this is normal.)
The air suspension shut-off switch is
located behind two access panels on
the left rear quarter trim panel, near
the liftgate. To remove the first
panel, turn the control
counterclockwise and remove the
panel.

Press the bottom portion of the
switch to turn off the air
suspension.
LIMITED-SLIP AXLE (IF EQUIPPED)
This axle provides added traction on slippery surfaces, particularly when
one wheel is on a poor traction surface. Under normal conditions, the
limited slip axle functions like a standard rear axle.
Extended use of other than the manufacturer ’ s specified size tires on a
limited slip rear axle could result in a permanent reduction in
effectiveness. This loss of effectiveness does not affect normal driving
and should not be noticeable to the driver.
PREPARING TO DRIVE YOUR VEHICLE
Utility vehicles have a significantly higher rollover rate than
other types of vehicles.
In a rollover crash, an unbelted person is significantly more likely
to die than a person wearing a seat belt.
Your vehicle has special design and equipment features to make it
capable of performing in a wide variety of circumstances. These special
design features, such as larger tires and increased ground clearance, give
the vehicle a higher center of gravity than a passenger car.
2004 Navigator (nav)
Owners Guide (post-2002-fmt)
USA English (fus) Driving
227

Vehicles with a higher center of gravity such as utility and
four-wheel drive vehicles handle differently than vehicles with a
lower center of gravity. Utility and four-wheel drive vehicles are not
designed for cornering at speeds as high as passenger cars any more
than low-slung sports cars are designed to perform satisfactorily under
off-road conditions. Avoid sharp turns, excessive speed and abrupt
maneuvers in these vehicles. Failure to drive cautiously could result in
an increased risk of loss of vehicle control, vehicle rollover, personal
injury and death.
Loaded vehicles, with a higher center of gravity, may handle
differently than unloaded vehicles. Extra precautions, such as
slower speeds and increased stopping distance, should be taken when
driving a heavily loaded vehicle.
Your vehicle has the capability to haul more cargo and people than most
passenger cars. Depending upon the type and placement of the load,
hauling people and cargo may raise the center of gravity of the vehicle.
Use extra caution while becoming familiar with your vehicle. Know the
capabilities and limitations of both you as a driver and your vehicle.
ROLL STABILITY CONTROL STABILITY ENHANCEMENT SYSTEM
(IF EQUIPPED)
The Roll Stability Control system provides a stability enhancement
feature as well as a traction enhancement feature. It helps your vehicle
maintain traction, when driving on slippery and/or hilly road surfaces, by
detecting and controlling wheel spin. Excessive wheel spin is controlled
by momentarily reducing engine power and rapidly applying the anti-lock
brakes. The system is a driver aid which makes your vehicle easier to
handle primarily on snow and ice-covered roads.
If your vehicle should become stuck in deep snow or mud, try switching
the Roll Stability Control system off by pressing the Roll Stability Control
button. This will allow your tires to “ dig ” for traction.
If the Roll Stability Control system is activated and deactivated
excessively in a short period of time, the brake portion of the system will
shut down to allow the brakes to cool down. A limited Roll Stability
Control function using only engine power reduction will still help control
the wheels from over-spinning. When the brakes have cooled down, the
system will again function normally. Anti-lock braking is not affected by
this condition and will function normally during the cool-down period.

Roll Stability Control enhances your vehicle ’ s stability during maneuvers
that require all available tire traction, like in wet/snowy/icy road
conditions and/or when performing emergency maneuvers. In an
emergency lane-change, the driver will experience better overall vehicle
traction, and have better control of the vehicle.
The Roll Stability Control system helps the driver maintain steering
control if the vehicle begins to slide excessively left or right or spin out.
Roll Stability Control will attempt to correct the sliding motion by
applying brake force at individual tires and, if necessary, by reducing
engine power.
Driving conditions which may activate Roll Stability Control include:
• Taking a turn too fast
• Maneuvering quickly to avoid an accident, pedestrian or obstacle
• Hitting a patch of ice
• Changing lanes on a snow-rutted road
• Entering a snow-free road from a snow-covered side street, or vice
versa
• Entering a paved road from a gravel road, or vice versa
• Hitting a curb while turning
• Driving on slick surfaces
• Cornering while towing a heavily loaded trailer (refer to Trailer
Towing in this chapter)
The Roll Stability Control (RSC) system works in to further enhance the
vehicle ’ s overall stability during aggressive maneuvers. The system helps
maintain roll stability of the vehicle during aggressive maneuvers by
applying brake force to one or more wheels.
Driving conditions that may activate Roll Stability Control include:
• Emergency lane-change
• Taking a turn too fast
• Quick maneuvering to avoid an accident, pedestrian or obstacle
• Hitting a curb while turning
The Roll Stability Control system automatically turns on when the engine
is started. However, the system does not function when the vehicle is
traveling in R (Reverse) or, if equipped with four-wheel drive, in 4L (4X4
LOW). In R (Reverse) or in 4L (4X4 LOW), ABS and the traction
enhancement feature will continue to function.

The Roll Stability Control button
allows the driver to control the
availability of the Roll Stability
Control system. The Roll Stability
Control system status is indicated
by a warning indicator light with a
“ sliding car ” icon in the instrument cluster that will flash when the
system is activated and an indicator light in the control button that will
illuminate when the system is turned off. In vehicles with a message
center, the message “ Roll Stability Control OFF ” will be displayed.
If a failure is detected in the Roll Stability Control system, the warning
indicator light in the instrument cluster will stay on. If the warning
indicator light in the instrument cluster remains on while the engine is
running, have the system serviced immediately.
Pressing the button once will disable the Roll Stability Control stability
enhancement and the engine power reduction portion of the traction
enhancement feature; the brake portion of the traction enhancement
feature will still function normally. Pressing and holding the button for
more than five seconds will disable the Roll Stability Control stability
enhancement and traction enhancement feature. If the vehicle is stuck
in snow or mud or when driving in deep sand, switching off the Roll
Stability Control system may be beneficial so the wheels are allowed to
spin. If your vehicle seems to lose engine power while driving in deep
sand or very deep snow, switching off the Roll Stability Control stability
enhancement feature will restore full engine power and will enhance
momentum through the obstacle.
Some drivers may notice a slight movement of the brake pedal when the
Roll Stability Control performs a system self-check. During Roll Stability
Control operation you may experience the following:
• A rumble or grinding noise
• A slight deceleration of the vehicle
• The Roll Stability Control indicator light will flash
• If your foot is on the brake pedal, you will feel a vibration in the
pedal.
• If the driving condition is severe and your foot is not on the brake, the
brake pedal will move to apply higher brake forces. You may also hear
a whoosh of air from under the instrument panel during this severe
condition.
All these conditions are normal during Roll Stability Control operation. O

be slightly delayed. Once the engine coolant temperature reaches 71 ° C
(160 ° F) the normal shift strategy will resume. This is normal operation
and will not affect the function or the durability of the transmission.
If the normal shift strategy does not resume once the engine
coolant temperature reaches the normal operating temperature,
or if the downshifts and other throttle conditions do not function
normally, see your dealer or a qualified service technician as soon
as possible.
Understanding gearshift positions
To put your vehicle in gear, start the engine, depress the brake pedal,
then move gearshift lever out of P (Park).
Hold the brake pedal down while you move the gearshift lever
from P (Park) to another position. If you do not hold the brake
pedal down, your vehicle may move unexpectedly and injure someone.
P (Park)
Always come to a complete stop
before shifting into P (Park). Make
sure the gearshift lever is securely
latched in P (Park). This position
locks the transmission and prevents
the rear wheels from turning.
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. P

throttle conditions do not function normally, see your dealer or a
qualified service technician as soon as possible.
If your vehicle gets stuck in mud or snow
If your vehicle gets stuck in mud or snow, it may be rocked out by
shifting from forward and reverse gears, stopping between shifts in a
steady pattern. Press lightly on the accelerator in each gear.
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 minute or damage to the
transmission and tires may occur, or the engine may overheat.
If your vehicle is equipped with AdvanceTrac
, it may be beneficial to
turn the system off so the wheels are allowed to spin.
EXTENDED REAR PARK ASSIST
The extended rear park assist system sounds a tone to warn the driver
of obstacles near the rear bumper when R (Reverse) gear is selected.
To help avoid personal injury, please read and understand the
limitations of the extended rear park assist system as contained
in this section. The park assist is only an aid for some (generally large
and fixed) objects when moving in reverse on a flat surface at “ parking
speeds ” . Inclement weather may also affect the function of the system;
this may include reduced performance or a false activation.
To help avoid personal injury, always use caution when in R
(Reverse) and when using the extended rear park assist.
This system is not designed to prevent contact with small or
moving objects. The system is designed to provide a warning to
assist the driver in detecting objects to avoid damaging the vehicle.
The system may not detect smaller objects, particularly those close to
the ground.
Certain add-on devices such as large trailer hitches, bike or
surfboard racks and any device that may block the normal
detection zone of the RSS system may create false beeps.
The system will assist the driver in detecting certain objects while the
vehicle slowly moves in reverse at speeds less than 10 km/h (6 mph).
