RUNNING OUT OF FUEL
Running out of fuel can cause damage not
covered by the vehicle Warranty.
If your vehicle runs out of fuel:
•
Add a minimum of 1.3 gal (5 L) of fuel to
restart the engine.
• You may need to switch the ignition from
off to on several times after refueling to
allow the fuel system to pump the fuel
from the tank to the engine. When
restarting, cranking time takes a few
seconds longer than normal.
Note: If your vehicle is on a steep slope,
more fuel may be required.
Filling a Portable Fuel Container WARNING:
Flow of fuel through a
fuel pump nozzle can produce static
electricity. This can cause a fire if you are
filling an ungrounded fuel container. Use the following guidelines to avoid
electrostatic charge build-up, which can
produce a spark, when filling an ungrounded
fuel container:
•
Only use an approved fuel container to
transfer fuel to your vehicle. Place the
container on the ground when filling it.
• Do not fill a fuel container when it is
inside your vehicle (including the cargo
area).
• Keep the fuel pump nozzle in contact
with the fuel container when filling it.
• Do not use a device that holds the fuel
pump nozzle lever in the fill position.
Adding Fuel From a Portable Fuel
Container WARNING: Do not insert the nozzle
of a fuel container or an aftermarket funnel
into the fuel filler neck. This may damage
the fuel system filler neck or its seal and
cause fuel to run onto the ground. WARNING:
Do not try to pry open or
push open the capless fuel system with
foreign objects. This could damage the fuel
system and its seal and cause injury to you
or others. WARNING: Do not dispose of fuel in
the household refuse or the public sewage
system. Use an authorized waste disposal
facility.
When refueling the vehicle fuel tank from a
fuel container, use the fuel filler funnel
included with your vehicle.
See Fuel Filler
Funnel Location (page 216).
Note: Do not use aftermarket funnels as they
may not work with the capless fuel system
and can damage it.
When refueling the vehicle fuel tank from a
fuel container, do the following:
1. Fully open the fuel filler door.
2. Fully insert the fuel filler funnel into the fuel filler inlet.
217

9. Fully close the fuel filler door.
Note:
The message may not immediately
reset. If the message continues to appear
and a warning lamp illuminates, have your
vehicle checked as soon as possible.
FUEL CONSUMPTION
Advertised Capacity
The advertised capacity is the maximum
amount of fuel that you can add to the fuel
tank when the fuel gauge indicates empty.
See Capacities and Specifications (page
440).
In addition, the fuel tank contains an empty
reserve. The empty reserve is an unspecified
amount of fuel that remains in the fuel tank
when the fuel gauge indicates empty.
Note: When refueling your vehicle after the
fuel gauge indicates empty, you might not
be able to refuel the full amount of the
advertised capacity due to the empty
reserve still present in the fuel tank. Filling the Fuel Tank
For consistent results when refueling:
•
Turn the ignition off before fueling; an
inaccurate reading results if the engine
is left running.
• Use the same fill rate (low-medium-high)
each time the tank is filled.
• Allow no more than one automatic
shut-off when refueling.
Results are most accurate when the filling
method is consistent.
Calculating Fuel Economy
Your vehicle calculates fuel economy figures
through the trip computer average fuel
function.
See Information Displays (page
134).
The first 1,000 mi (1,500 km) of driving is the
break-in period of the engine. A more
accurate measurement is obtained after
2,000 mi (3,000 km)
.
1. Completely fill the fuel tank and record the initial odometer reading. 2.
Each time you fill the fuel tank, record the
amount of fuel added.
3. After at least three fill ups, fill the fuel tank and record the current odometer
reading.
4. Subtract your initial odometer reading from the current odometer reading.
To calculate L/100 km (liters per 100
kilometers) fuel consumption, multiply the
liters used by 100, then divide by kilometers
traveled. To calculate MPG (miles per gallon)
fuel consumption, divide miles traveled by
gallons used.
Keep a record for at least one month and
record the type of driving, for example city
or highway. This provides an accurate
estimate of your vehicle ’s fuel economy
under current driving conditions. Keeping
records during summer and winter shows
how temperature impacts fuel economy.

•
An open or pinched sensor hose.
• Incorrect engine oil level.
• Incorrect fuel for climatic conditions.
• Incorrect engine oil viscosity for climactic
conditions.
Note: Some vehicles have a lifetime fuel filter
that is integrated with the fuel tank. Regular
maintenance or replacement is not needed.
Note: If these checks do not help you correct
the concern, have your vehicle checked as
soon as possible.
Noise Emissions Warranty, Prohibited
Tampering Acts and Maintenance
On January 1, 1978, Federal regulation
became effective governing the noise
emission on trucks over 10,000 lb (4,536 kg)
Gross Vehicle Weight Rating (GVWR). The
preceding statements concerning prohibited
tampering acts and maintenance, and the
noise warranty found in the Warranty Guide,
are applicable to complete chassis cabs over
10,000 lb (4,536 kg)
GVWR. CATALYTIC CONVERTER WARNING:
Do not park, idle or drive
your vehicle on dry grass or other dry
ground cover. The emission system heats
up the engine compartment and exhaust
system, creating the risk of fire. WARNING:
The normal operating
temperature of the exhaust system is very
high. Never work around or attempt to
repair any part of the exhaust system until
it has cooled. Use special care when
working around the catalytic converter.
The catalytic converter heats up to a very
high temperature after only a short period
of engine operation and stays hot after the
engine is switched off. WARNING: Exhaust leaks may result
in entry of harmful and potentially lethal
fumes into the passenger compartment. If
you smell exhaust fumes inside your
vehicle, have your vehicle inspected
immediately. Do not drive if you smell
exhaust fumes. Your vehicle has various emission control
components and a catalytic converter that
enables it to comply with applicable exhaust
emission standards.
To make sure that the catalytic converter and
other emission control components continue
to work properly:
•
Do not crank the engine for more than
10 seconds at a time.
• Do not run the engine with a spark plug
lead disconnected.
• Do not push-start or tow-start your
vehicle. Use booster cables.
See Jump
Starting the Vehicle (page 346).
• Use only the specified fuel listed.
• Do not switch the ignition off when your
vehicle is moving.
• Avoid running out of fuel.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
Note: Resulting component damage may
not be covered by the vehicle Warranty.

If the service engine soon indicator remains
on, have your vehicle serviced at the first
available opportunity. Although some
malfunctions detected by the OBD-II may not
have symptoms that are apparent, continued
driving with the service engine soon indicator
on can result in increased emissions, lower
fuel economy, reduced engine and
transmission smoothness and lead to more
costly repairs.
Readiness for Inspection and
Maintenance (I/M) Testing
Some state and provincial and local
governments may have
Inspection/Maintenance (I/M) programs to
inspect the emission control equipment on
your vehicle. Failure to pass this inspection
could prevent you from getting a vehicle
registration.
If the service engine soon indicator
is on or the bulb does not work,
your vehicle may need service.
See On-Board Diagnostics. Your vehicle may not pass the I/M test if the
service engine soon indicator is on or not
working properly (bulb is burned out), or if
the OBD-II system has determined that some
of the emission control systems have not
been properly checked. In this case, the
vehicle is not ready for I/M testing.
If the vehicle
’s engine or transmission has
just been serviced, or the battery has
recently run down or been replaced, the
OBD-II system may indicate that the vehicle
is not ready for I/M testing. To determine if
the vehicle is ready for I/M testing, turn the
ignition key to the on position for 15 seconds
without cranking the engine. If the service
engine soon indicator blinks eight times, it
means that the vehicle is not ready for I/M
testing; if the service engine soon indicator
stays on solid, it means that your vehicle is
ready for I/M testing.
The OBD-II system checks the emission
control system during normal driving. A
complete check may take several days.
If the vehicle is not ready for I/M testing, you
can perform the following driving cycle
consisting of mixed city and highway driving: 1. 15 minutes of steady driving on an
expressway or highway followed by 20
minutes of stop-and-go driving with at
least four 30-second idle periods.
2. Allow your vehicle to sit for at least eight
hours with the ignition off. Then, start the
vehicle and complete the above driving
cycle. The vehicle must warm up to its
normal operating temperature. Once
started, do not turn off the vehicle until
the above driving cycle is complete.
If the vehicle is still not ready for I/M testing,
you need to repeat the above driving cycle.

AUTOMATIC TRANSMISSION
WARNING: Always fully apply the
parking brake and make sure you shift into
park (P). Failure to follow this instruction
could result in personal injury or death. WARNING:
Do not use tow/haul
when the road surface is slippery. Failure
to follow this instruction could result in the
loss of control of your vehicle. WARNING:
When your vehicle is
stationary, keep the brake pedal fully
pressed when shifting gears. Failure to
follow this instruction could result in
personal injury, death or property damage.

your Automatic Transmission
Putting your vehicle in or out of gear:
1. Fully press down on the brake pedal.
2. Press the desired gear on the
transmission selector.
3. When you finish driving, come to a complete stop.
4. Press the park (P) button on the transmission selector.
The instrument cluster displays the current
gear. Park (P)
With the transmission in park (P), your vehicle
locks the transmission and prevents the
wheels from turning. Always come to a
complete stop before putting your vehicle
into and out of park (P). An audible tone
sounds once you select park (P).
When the ignition is off, your vehicle
automatically shifts into park (P). If the ignition
is off when the vehicle is moving, it first shifts
into neutral (N) until the vehicle stops, and
then shift into park (P) automatically.
The electric parking brake may apply when
you shift to park (P) without the brake pedal
fully pressed. The electric parking brake
applies when you shift to park (P) on large
slopes. The electric parking brake releases
with the drive away release function or
manually as described in the Releasing the
Electric Parking Brake section.
See Electric
Parking Brake (page 242).
Automatic Return to Park
Note: This feature does not operate when
your vehicle is in Stay in Neutral mode or
neutral tow.
227
Navigator (TB9) Canada/United States of America, enUSA, First-Printing TransmissionE247220

Your vehicle has a feature that automatically
shifts your vehicle into park (P) when any of
the following conditions occur:
•
You turn the vehicle off.
• You open the driver's door with your
seatbelt unlatched with the vehicle
stopped.
• You unlatch your seatbelt when the
driver's door is open with the vehicle
stopped.
If you turn your vehicle off when moving,
your vehicle first shifts into neutral (N) until
it stops and then shift into park (P)
automatically.
Note: If you have waited an extended period
of time, 2-15 minutes before starting your
vehicle, unlatching your seatbelt can cause
this feature to activate, even with the driver
door closed.
Note: This feature may not work properly if
the door ajar switch is malfunctioning. If your
door ajar indicator does not illuminate when
you open the driver’ s door or the indicator
illuminates with the driver’ s door closed, see
your authorized dealer. Reverse (R)
With the selector in reverse (R), your vehicle
moves backward. Always come to a
complete stop before shifting into and out
of reverse (R).
Neutral (N)
With the selector in neutral (N), you can start
your vehicle and is free to roll. Hold the
brake pedal down when in this position.
Stay in Neutral Mode
Stay in Neutral mode allows your vehicle to
stay in neutral when you exit your vehicle.
Your vehicle must be stationary to enter this
mode.
Note:
Stay in neutral mode is a temporary
vehicle state with the ignition off. Once in
this mode, sufficient battery voltage must be
maintained or your vehicle returns to park.
Extended usage of Stay in Neutral mode
may result in a battery voltage reduction to
a level where the vehicle may no longer
start. Do not tow your vehicle in this mode. Note:
Always put your vehicle in Stay in
Neutral mode when entering an automatic
car wash. Failure to do this could result in
vehicle damage not covered by warranty.
To enter Stay in Neutral mode:
• Press the neutral (N) button on the
transmission selector.
• Press the neutral (N) button again to
enter Stay in Neutral mode.
A message appears in your information
display screen when your vehicle has
entered Stay in Neutral mode.
To exit Stay in Neutral mode, apply the brake
and select a different gear.
Stay in Neutral Mode - No Start
Use this to move your transmission from the
park position in the event of a no start
situation. If your vehicle has a dead battery,
you require an external power source. Do
not tow your vehicle in this mode.

Mud and Water
If you must drive through high water, drive
slowly. Traction or brake capability could be
limited.
When driving through water, determine the
depth and avoid water higher than the
bottom of the hubs. If the ignition system
gets wet, your vehicle may stall.
Once through water, always try the brakes.
Wet brakes do not stop your vehicle as
effectively as dry brakes. Drying can be
improved by applying light pressure to the
brake pedal when slowly moving.
Be cautious of sudden changes in vehicle
speed or direction when you are driving in
mud. Even four-wheel drive 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, transfer case or front axle
are submerged in water, their fluids should
be checked and changed, if necessary.
If the front or rear axle is submerged in water,
the axle lubricant should be replaced.
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.
Note:
Driving through deep water could
damage the vehicle.
Driving on Hilly or Sloping Terrain
Although natural obstacles may make it
necessary to travel diagonally up or down a
hill or steep incline, you should always try to
drive straight up or straight down.
When climbing a steep slope or hill, start in
a lower gear rather than downshifting to a
lower gear from a higher gear once the
ascent has started. This reduces strain on
the engine and the possibility of stalling.
If your vehicle stalls, do not try to turn around
because this could cause vehicle roll over.
It is better to reverse back to a safe location. Apply just enough power to the wheels to
climb the hill. Too much power causes the
tires to slip, spin or lose traction, resulting in
loss of vehicle control.
Descend a hill in the same gear you would
use to climb up the hill to avoid excessive
brake application and brake overheating. Do
not descend in neutral. Disengage overdrive
or move the transmission selector lever to a
lower gear. When descending a steep hill,
avoid sudden hard braking as you could lose
control. The front wheels have to be turning
in order to steer your vehicle.
If your vehicle has anti-lock brakes, apply the
brakes steadily. Do not pump the brakes.

GENERAL INFORMATION
Note:
Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings could be worn-out, you should
have them checked. If the vehicle has
continuous vibration or shudder in the
steering wheel while braking, you should
have the system checked.
Note: Brake dust may accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise. See Cleaning the Wheels
(page 403). See
Warning Lamps and
Indicators (page 129).
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when driving from a car wash or
standing water to dry the brakes. Brake Over Accelerator
In the event the accelerator pedal becomes
stuck or entrapped, apply steady and firm
pressure to the brake pedal to slow the
vehicle and reduce engine power. If you
experience this condition, apply the brakes
and bring your vehicle to a safe stop. Switch
the engine off, move the transmission to park
(P) and apply the parking brake. Inspect the
accelerator pedal and the area around it for
any items or debris that may be obstructing
its movement. If none are found and the
condition persists, do not drive your vehicle.
Have your vehicle towed to the location you
are having it checked.
Emergency Brake Assist
Emergency brake assist detects when you
brake heavily by measuring the rate at which
you press the brake pedal. It provides
maximum braking efficiency as long as you
press the pedal. Emergency brake assist
can reduce stopping distances in critical
situations.Anti-lock Brake System
This system helps you maintain steering
control during emergency stops by keeping
the brakes from locking. This lamp momentarily illuminates
when you switch the ignition on.
If the light does not illuminate
during start up, remains on or flashes, the
anti-lock braking system may be disabled.
Have the system checked. If the anti-lock
brake system is disabled, normal braking is
still effective. If the brake warning lamp
illuminates with the parking brake
released, have your brake system
serviced immediately.
It also illuminates momentarily when you
switch the ignition on to confirm the lamp is
functional. If it does not illuminate when you
switch the ignition on, or begins to flash at
any time, have the system checked.

HINTS ON DRIVING WITH ANTI-
LOCK BRAKES
The anti-lock braking system does not
eliminate the risks when:
•
You drive too closely to the vehicle in
front of you.
• Your vehicle is hydroplaning.
• You take corners too fast.
• The road surface is poor.
Note: If the system activates, the brake
pedal may pulse and may travel further.
Maintain pressure on the brake pedal. You
may also hear a noise from the system. This
is normal.
ELECTRIC PARKING BRAKE WARNING: Always fully apply the
parking brake and make sure you shift into
