4WD LINCOLN NAVIGATOR 2012 Navigation Manual

VEHICLE CHARACTERISTICS
Four-wheel drive (4WD) system (if equipped)
A vehicle equipped with 4WD (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. 4WD vehicles allow you to select different drive modes as
necessary. Information on transfer case operation and shifting procedures
can be found in theDrivingchapter. Information on transfer case
maintenance can be found in theMaintenance and Specifications
chapter. You should become thoroughly familiar with this information
before you operate your vehicle.
On some 4WD models, the initial shift from two-wheel drive to 4WD
while the vehicle is moving can cause a momentary clunk and ratcheting
sound. These sounds are normal as the front drivetrain comes up to
speed and is not cause for concern.
WARNING:Do not become overconfident in the ability of 4WD
vehicles. Although a 4WD vehicle may accelerate better than
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.

Tire and wheel alignment
A bad jolt from hitting a curb or pothole can cause the front end of your
vehicle to become misaligned or cause damage to your tires. If your
vehicle seems to pull to one side when you’re driving, the wheels may be
out of alignment. Have an authorized dealer check the wheel alignment
periodically.
Wheel misalignment in the front or the rear can cause uneven and rapid
treadwear of your tires and should be corrected by an authorized dealer.
Front-wheel drive (FWD) vehicles and those with an independent rear
suspension (if equipped) may require alignment of all four wheels.
The tires should also be balanced periodically. An unbalanced tire and
wheel assembly may result in irregular tire wear.
Tire rotation
Rotating your tires at the recommended interval (as indicated in your
scheduled maintenance) will help your tires wear more evenly, providing
better tire performance and longer tire life.
•Rear-wheel drive (RWD)
vehicles/Four-wheel drive (4WD)
vehicles (front tires at top of
diagram)
Sometimes irregular tire wear can be corrected by rotating the tires.
Note:If your tires show uneven wear ask an authorized dealer to check
for and correct any wheel misalignment, tire imbalance or mechanical
problem involved before tire rotation.
Note:Your vehicle may be equipped with a dissimilar spare tire/wheel. A
dissimilar spare tire/wheel is defined as a spare tire and/or wheel that is
different in brand, size or appearance from the road tires and wheels. If
you have a dissimilar spare tire/wheel it is intended for temporary use
only and should not be used in a tire rotation.
Note:After having your tires rotated, inflation pressure must be checked
and adjusted to the vehicle requirements.

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 any time the axle has been submerged in
water. Rear axle lubricant quantities are not to be checked or changed
unless a leak is suspected or repair required.
RECREATIONAL TOWING
Follow these guidelines if you have a need for recreational towing. An
example of recreational towing would be towing your vehicle behind a
motorhome. These guidelines are designed to ensure that your
transmission is not damaged.
Note:Put your climate control system in recirculated air mode to
prevent exhaust fumes from entering the vehicle. Refer to theClimate
Controlschapter for more information.
2WD and 4WD vehicles:Do not tow your vehicle with any wheels on
the ground, as vehicle or transmission damage may occur. It is
recommended to tow your vehicle with all four (4) wheels off the ground
such as when using a car-hauling trailer. Otherwise, no recreational
towing is permitted. See your authorized dealer if you must flat-tow a
vehicle equipped with the Control Trac4WD system.
In case of a roadside emergency with a disabled vehicle, seeWrecker
towingin theRoadside Emergencieschapter.

CONTROL TRACFOUR-WHEEL DRIVE (4X4) OPERATION
(IF EQUIPPED)
WARNING:For important information regarding safe operation
of this type of vehicle, seePreparing to drive your vehiclein
this chapter.
Do not use 4X4 mode on dry, hard surfaced roads. Doing so will produce
excessive noise, increase tire wear and may damage drive components.
4X4 mode is only intended for consistently slippery or loose surfaces.
Use of 4X4 mode on these surfaces may produce some noise (such as
occasional clunks) but will not damage drive components.
Your 4x4 features the heavy-duty Control Trac system which includes a
computer-operated transfer case. This unique system is interactive with
the road, continually monitoring and adjusting torque delivery to the
front and rear wheels to optimize vehicle control.
4WD indicator lights
The indicator lights illuminate in the message center in the
reconfigurable telltale (RTT) location under the following conditions.
Refer toWarning lights and chimesin theInstrument Clusterchapter.
•4X2- Momentarily illuminates
when 2H is selected.
•4X4 AUTO– Illuminates when
4X4 AUTO is selected.
•4X4– Illuminates when 4X4 is
selected.
•CHECK 4X4 (if equipped)-
Displays when a 4X4 fault is
present.
Note:When a 4x4 system fault is present, the system will typically
remain in whichever 4X4 mode was selected prior to the fault condition
occurring. It will not default to 4X2 mode in all circumstances. When this
warning is displayed, have your vehicle serviced by an authorized dealer.
