Shifting to or from 4L - 4X4 LOW
Note:
4L mode is not intended for use on dry
pavement.
1. Bring the vehicle to a rolling speed of 3 mph (5 km/h) or less.
2. Place the gearshift in neutral (N).
3. Rotate the drive mode knob to desired mode.
The information display shows a message
indicating a 4X4 shift is in progress. The
information display shows the system mode
selected. If any of the previous shift
conditions are not present, the shift does not
occur and the information display shows the
information guiding the driver through the
proper shifting procedures. If the previous
conditions are not satisfied in 30 seconds,
the system reverts back to the previous 4WD
mode or drive mode. If
Shift Delayed Pull Forward displays in the
information display, transfer case gear tooth
blockage is present. To alleviate this
condition, place the transmission in a forward
gear, move the vehicle forward
approximately
5 ft (2 m), and shift the
transmission back to neutral (N) to allow the
transfer case to complete the range shift.
Operating 4WD Vehicles with Spare or
Mismatched Tires
On four-wheel drive vehicles, the size of the
spare tire can affect the 4X4 system. If there
is a significant difference between the size
of the spare tire and the remaining tires, you
may have limited four-wheel drive
functionality.
When driving with the full-size dissimilar
spare wheel and tire assembly, it is
recommended that you do not:
• Exceed
50 mph (80 km/h) with a 4WD
mode turned on.
• Turn on a 4WD mode unless the vehicle
is stationary.
• Use a 4WD mode on dry pavement. Use of a dissimilar spare wheel and tire
assembly may lead to impairment of the
following:
•
Comfort and noise.
• Winter weather driving capability.
• Wet driving capability.
• Four-wheel drive capability.
How Your Vehicle Differs from Other
Vehicles WARNING:
Vehicles with a higher
center of gravity (utility and four-wheel
drive vehicles) handle differently than
vehicles with a lower center of gravity
(passenger cars). Avoid sharp turns,
excessive speed and abrupt steering in
these vehicles. Failure to drive cautiously
increases the risk of losing control of your
vehicle, vehicle rollover, personal injury
and death.

PRINCIPLE OF OPERATION
WARNING: Vehicle modifications
involving braking system, aftermarket roof
racks, suspension, steering system, tire
construction and wheel and tire size may
change the handling characteristics of your
vehicle and may adversely affect the
performance of the electronic stability
control system. In addition, installing any
stereo loudspeakers may interfere with
and adversely affect the electronic stability
control system. Install any aftermarket
stereo loudspeaker as far as possible from
the front center console, the tunnel, and
the front seats in order to minimize the risk
of interfering with the electronic stability
control sensors. Reducing the
effectiveness of the electronic stability
control system could lead to an increased
risk of loss of vehicle control, vehicle
rollover, personal injury and death. WARNING:
Remember that even
advanced technology cannot defy the laws
of physics. It’ s always possible to lose
control of a vehicle due to inappropriate
driver input for the conditions. Aggressive
driving on any road condition can cause
you to lose control of your vehicle
increasing the risk of personal injury or
property damage. Activation of the
electronic stability control system is an
indication that at least some of the tires
have exceeded their ability to grip the
road; this could reduce the operator’ s
ability to control the vehicle potentially
resulting in a loss of vehicle control, vehicle
rollover, personal injury and death. If your
electronic stability control system activates,
SLOW DOWN.
The system automatically turns on each time
you switch the ignition on.
If a fault occurs in either the stability control
or the traction control system, you may
experience the following conditions: •
The stability and traction control light
illuminates steadily.
• The stability control and traction control
systems do not enhance your vehicle's
ability to maintain traction of the wheels.
If a driving condition activates either the
stability control or the traction control system
you may experience the following conditions:
• The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced engine power.
• A vibration in the brake pedal.
• The brake pedal is stiffer than usual.
• If the driving condition is severe and your
foot is not on the brake, the brake pedal
may move as the system applies higher
brake force.
The stability control system has several
features built into it to help you maintain
control of your vehicle:

WARNING: Active park assist does
not apply the brakes under any
circumstances. WARNING:
You are responsible for
controlling your vehicle at all times. The
system is designed to be an aid and does
not relieve you of your responsibility to
drive with due care and attention. Failure
to follow this instruction could result in the
loss of control of your vehicle, personal
injury or death.
Active park assist is a multi-step process and
may require you to shift the transmission
multiple times. Follow the onscreen
instructions until the parking maneuver is
complete.
If you are uncomfortable with the proximity
to any vehicle or object, you may choose to
override the system by grabbing the steering
wheel, or by taking full control of your vehicle
after pressing the active park assist button.
Keep your hands, hair, clothing and any
loose items clear of the steering wheel when
using active park assist. The sensors are on the front and rear
bumpers.
Note:
Keep the sensors free from snow, ice
and large accumulations of dirt.
Note: Do not cover up the sensors.
Note: Do not clean the sensors with sharp
objects.
Note: The sensors may not detect objects
with surfaces that absorb ultrasonic waves.
The sensors may falsely detect objects due
to ultrasonic interference caused by
motorcycle exhausts, truck air brakes or
horns, for example.
Note: If you change any tires, the system
must recalibrate and may not correctly
operate for a short time.
The system may not correctly operate in any
of the following conditions:
• You use a spare tire or a tire that is
significantly worn more than the other
tires.
• One or more tires are incorrectly inflated.
• You try to park on a tight curve. •
Something passes between the front
bumper and the parking space. For
example, a pedestrian or cyclist.
• The edge of the neighboring parked
vehicle is high off the ground. For
example, a bus, tow truck or flatbed
truck.
• The weather conditions are poor. For
example, during heavy rain, snow, fog,
high humidity and high temperatures.
Do not use the system if:
• You have attached an add-on accessory
close to the sensors on the front or rear
of your vehicle. For example, a bike rack
or trailer.
• You have attached an overhanging
object to the roof. For example, a
surfboard.
• The front bumper, rear bumper or the
side sensors are damaged.
• The correct tire size is not in use on your
vehicle. For example, a mini-spare tire.

Your vehicle may be equipped with a
temporary or conventional spare tire. A
temporary spare tire is different in size
(diameter or width), tread-type (All-Season
or All-Terrain) or is from a different
manufacturer than the road tires on your
vehicle. Consult information on the tire label
or Safety Compliance label for limitations
when using.
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note:
Disconnect the wiring to the trailer
before backing the trailer into the water.
Note: Reconnect the wiring to the trailer
after
removing the trailer from the water.
When backing down a ramp during boat
launching or retrieval:
• Do not allow the static water level to rise
above the bottom edge of the rear
bumper.
• Do not allow waves to break higher than
6 in (15 cm)
above the bottom edge of
the rear bumper. Exceeding these limits may allow water to
enter vehicle components:
•
Causing internal damage to the
components.
• Affecting driveability, emissions, and
reliability.
Replace the rear axle lubricant anytime the
rear axle has been submerged in water.
Water may have contaminated the rear axle
lubricant, which is not normally checked or
changed unless a leak is suspected or other
axle repair is required.
TOWING THE VEHICLE ON FOUR
WHEELS WARNING:
If your vehicle has a
steering wheel lock make sure the ignition
is in the accessory or on position when
being towed. Recreational Towing
Note:
Put your climate control system in
recirculated air mode to prevent exhaust
fumes from entering your vehicle.
See
Climate Control (page 165).
Follow these guidelines if you have a need
for recreational towing, such as towing your
vehicle behind a motorhome. These
guidelines are designed to prevent damage
to your transmission.
Two-wheel Drive Vehicles
You cannot tow a two-wheel drive vehicle
with any wheels on the ground as vehicle or
transmission damage may occur. You must
tow your vehicle with all four wheels off the
ground, for example when using a
car-hauling trailer.
Four-wheel Drive Vehicles Without
SLOW
CLIMB Mode
You cannot tow your vehicle with any wheels
on the ground or vehicle damage may occur.
You must tow your vehicle with all four
wheels off the ground, for example when
using a car-hauling trailer.

GENERAL INFORMATION
Use only approved wheel and tire sizes,
using other sizes could damage your vehicle.
If you change the diameter of the tires from
that fitted at the factory, the speedometer
may not display the correct speed. If you
intend to change the size of the wheels from
that fitted by the manufacturer, you can
check the suitability with an authorized
dealer.
Additional information related to the
functionality and maintenance of your tires
can be found later in this chapter. See Tire
Care (page 406).
You can find the recommended tire inflation
pressures can on the Tire Label, which is on
the B-pillar or the edge of the driver door.
You can also find this information on the
Safety Compliance Certification Label, affixed
to either the door hinge pillar, door-latch
post, or the door edge that meets the door
latch post; next to the driver seating position. We strongly recommend maintaining these
tire pressures at all times. Failure to follow
the tire pressure recommendations can
cause uneven treadwear patterns, reduced
fuel economy, and adversely affect the way
your vehicle handles.
Note:
Check and set the tire pressure at the
ambient temperature in which you are
intending to drive your vehicle and when the
tires are cold.
Note: Check your tire pressures at least once
per month.
If your vehicle has a spare tire, set the
pressure to the highest value given for your
vehicle and tire size combination.
Notice to utility vehicle and truck
owners WARNING:
Utility vehicles have a
significantly higher rollover rate than other
types of vehicles. WARNING:
Vehicles with a higher
center of gravity (utility and four-wheel
drive vehicles) handle differently than
vehicles with a lower center of gravity
(passenger cars). Avoid sharp turns,
excessive speed and abrupt steering in
these vehicles. Failure to drive cautiously
increases the risk of losing control of your
vehicle, vehicle rollover, personal injury
and death. WARNING:
In a rollover crash, an
unbelted person is significantly more likely
to die than a person wearing a seatbelt. WARNING:
Do not become
overconfident in the ability of four-wheel
drive vehicles. Although a four-wheel drive
vehicle may accelerate better than a
two-wheel drive vehicle in low traction
situations, it won't stop any faster than
two-wheel drive vehicles. Always drive at
a safe speed.
404
Navigator (TB9) Canada/United States of America, enUSA, Edition date: 201907, Second-Printing Wheels and Tires

Utility vehicles and trucks handle differently
than passenger cars in the various driving
conditions that are encountered on streets,
highways and off-road. Utility vehicles and
trucks 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.
Study your owner's manual and any
supplements for specific information about
equipment features, instructions for safe
driving and additional precautions to reduce
the risk of an accident or serious injury.
Four-wheel drive system (If Equipped)
WARNING:
Do not become
overconfident in the ability of four-wheel
drive vehicles. Although a four-wheel drive
vehicle may accelerate better than a
two-wheel drive vehicle in low traction
situations, it won't stop any faster than
two-wheel drive vehicles. Always drive at
a safe speed. A vehicle equipped with four-wheel drive,
when selected, has the ability to use all four
wheels to power itself. This increases traction
which may enable you to safely drive over
terrain and road conditions that a
conventional two-wheel drive vehicle cannot.
Power is supplied to all four wheels through
a transfer case or power transfer unit.
Four-wheel drive vehicles allow you to select
different modes as necessary. For
information on transfer case operation and
shifting procedures, See Four-Wheel Drive
(page 228). For information on transfer case
maintenance,
See Maintenance (page 373).
You should become thoroughly familiar with
this information before you operate your
vehicle.
On some four-wheel drive vehicles, the initial
shift from two-wheel to four-wheel drive
when the vehicle is moving can cause a
momentary clunk and ratcheting sound.
These sounds are normal and are not cause
for concern. In four-wheel drive vehicles, the size of the
spare tire relative to the remaining tires can
have an effect on the 4x4 system. If there is
a significant difference between the size of
a spare and the remaining tires, four-wheel
drive functionality may be limited. See Using
Four-Wheel Drive
(page 228).
How your vehicle differs from other
vehicles
Sport utility vehicles and trucks can differ
from some other vehicles in a few noticeable
ways. Your vehicle may be:

Treadwear
The treadwear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled conditions
on a specified government test course.
For example, a tire graded 150 would
wear one and one-half (1 ½) times as well
on the government course as a tire
graded 100. The relative performance
of tires depends upon the actual
conditions of their use, however, and
may depart significantly from the norm
due to variations in driving habits,
service practices, and differences in
road characteristics and climate.
Traction AA A B C
WARNING: The traction grade
assigned to this tire is based on
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning or peak
traction characteristics. The traction grades, from highest to
lowest are AA, A, B, and C. The grades
represent the tire
’s ability to stop on wet
pavement as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction
performance.
Temperature A B C WARNING:
The temperature
grade for this tire is established for a
tire that is properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive loading,
either separately or in combination,
can cause heat buildup and possible
tire failure.
The temperature grades are A (the
highest), B and C, representing the tire ’s
resistance to the generation of heat and
its ability to dissipate heat when tested
under controlled conditions on a
specified indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate
and reduce tire life, and excessive
temperature can lead to sudden tire
failure. The grade C corresponds to a
level of performance which all
passenger car tires must meet under the
Federal Motor Vehicle Safety Standard
No. 139. Grades B and A represent
higher levels of performance on the
laboratory test wheel than the minimum
required by law.
Glossary of Tire Terminology

Information on P Type Tires
P215/65R15 95H is an example of a tire
size, load index and speed rating. The
definitions of these items are listed
below. (Note that the tire size, load index
and speed rating for your vehicle may
be different from this example.) A. P: Indicates a tire, designated by the
Tire and Rim Association, that may be
used for service on cars, sport utility
vehicles, minivans and light trucks.
Note:
If your tire size does not begin with a
letter this may mean it is designated by
either the European Tire and Rim
Technical Organization or the Japan Tire
Manufacturing Association.
B.
215: Indicates the nominal width of
the tire in millimeters from sidewall edge
to sidewall edge. In general, the larger
the number, the wider the tire.
C.
65: Indicates the aspect ratio which
gives the tire's ratio of height to width.
D.
R: Indicates a radial type tire.
E.
15: Indicates the wheel or rim
diameter in inches. If you change your
wheel size, you will have to purchase
new tires to match the new wheel
diameter. F.
95: Indicates the tire's load index. It
is an index that relates to how much
weight a tire can carry. You may find this
information in your owner’ s manual. If
not, contact a local tire dealer.
Note: You may not find this information
on all tires because it is not required by
federal law.
G.
H: Indicates the tire's speed rating.
The speed rating denotes the speed at
which a tire is designed to be driven for
extended periods of time under a
standard condition of load and inflation
pressure. The tires on your vehicle may
operate at different conditions for load
and inflation pressure. These speed
ratings may need to be adjusted for the
difference in conditions. The ratings
range from
81 mph (130 km/h) to
186 mph (299 km/h). These ratings are
listed in the following chart.
Note: You may not find this information
on all tires because it is not required by
federal law.
