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 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 systems applies higher
brake forces.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
The system enhances your vehicle ’s ability
to prevent skids or lateral slides by applying
brakes to one or more of the wheels
individually and, if necessary, reducing
engine power.

STEERING
Electric Power Steering WARNING:
The electric power
steering system has diagnostic checks that
continuously monitor the system. If a fault
is detected, a message displays in the
information display. Stop your vehicle as
soon as it is safe to do so. Switch the ignition off. After at least 10 seconds,
switch the ignition on and watch the
information display for a steering system
warning message. If a steering system
warning message returns, have the system
checked as soon as possible.
WARNING: If the system detects an
error, you may not feel a difference in the
steering, however a serious condition may
exist. Have your vehicle checked as soon
as possible. Failure to do so may result in
loss of steering control. Your vehicle has an electric power steering
system. There is no fluid reservoir and
therefore requires no maintenance.
If your vehicle loses electrical power when
you are driving, electric power steering
assistance is lost. The steering system still
operates and you can manually steer your
vehicle. Manually steering your vehicle
requires more effort.
322
Aviator (CTV) Canada/United States of America, enUSA, Edition date: 202007, Second-Printing Driving Aids

Extreme continuous steering could increase
the effort you need to steer your vehicle. This
increased effort prevents overheating and
permanent damage to the steering system.
You do not lose the ability to manually steer
your vehicle. Typical steering and driving
maneuvers allow the system to cool and
operate as normal.
Steering Tips
If the steering wanders or pulls, check for:
•
Correct tire pressures.
• Uneven tire wear.
• Loose or worn suspension components.
• Loose or worn steering components.
• Improper vehicle alignment.
Note: A high crown in the road or high
crosswinds could also make the steering
seem to wander or pull. Adaptive Learning
The electronic power steering system
adaptive learning improves overall handling
and steering on roads with irregularities. It
communicates with the brake system to help
operate advanced stability control and
accident avoidance systems. When you
install a new battery or disconnect the
battery, you need to drive your vehicle a
short distance so it can relearn and reactivate
all systems.
PRE-COLLISION ASSIST
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. WARNING:
The system does not
detect vehicles that are driving in a
different direction, cyclists or animals.
Apply the brakes when necessary. Failure
to follow this instruction could result in the
loss of control of your vehicle, personal
injury or death. WARNING:
The system does not
operate during hard acceleration or
steering. Failure to take care may lead to
a crash or personal injury. WARNING:
The system may fail or
operate with reduced function during cold
and severe weather conditions. Snow, ice,
rain, spray and fog can adversely affect the
system. Keep the front camera and radar
free of snow and ice. Failure to take care
may result in the loss of control of your
vehicle, serious personal injury or death.

WHAT IS DRIVE MODE CONTROL
The system delivers a driving experience
through a suite of sophisticated electronic
vehicle systems. These systems optimize
steering, handling and powertrain response.
This provides a single location to control
multiple systems performance settings.
Changing the drive mode automatically
changes the functionality of the following
systems:
•
Electronically power-assisted steering
system adjusts steering effort and feel
based on the mode you select. See
Steering (page 322).
• Electronic stability control and traction
control maintains your vehicle control in
adverse conditions or high performance
driving. See Stability Control (page 268).
• Electronic throttle control enhances the
powertrain response to your driving
inputs.
• Transmission controls optimize with shift
schedules tuned to each mode.
• AWD settings become optimized and
tuned to each mode. The system automatically tailors your vehicle
configuration for each mode you select.
Note:
Not all settings, or modes, may be
available.
Note: The system has diagnostic checks that
continuously monitor the system for proper
operation. If a mode is unavailable due to a
system fault, the mode defaults to Normal.
SELECTING A DRIVE MODE
Note: Drive mode changes may not be
available when the ignition is off. Rotate the drive mode dial on the center
console to change the drive mode.
DRIVE MODES
Conserve
Enables efficient driving. It helps to deliver
maximum fuel efficiency and helps to
increase driving range.
Deep Conditions
(If Equipped)
For crossing terrain that has deformable
deep, rutted surfaces such as mud, deep
sand or deep snow. Do not use on dry, hard
surfaced roads.
If your vehicle has air suspension, it raises
approximately
1.2 in (30 mm) at low speeds
for improved ground clearance.
Note: Using deep conditions mode on dry
hard surfaces could produce some vibration,
driveline bind up, and potential excessive
tire wear. This mode is for slippery and loose
surfaces.
329
Aviator (CTV) Canada/United States of America, enUSA, Edition date: 202007, Second-Printing Drive Mode ControlE297680

Deep Sand (If Equipped)
For crossing deep soft and dry sand.
Note: Using deep sand mode on dry hard
surfaces could produce some vibration,
driveline bind up, and potential excessive
tire wear. This mode is for slippery and loose
surfaces.
Excite
For sporty on-road driving. This mode
increases throttle response, provides a more
dynamic powertrain sound and steering feel,
along with a more sporty shifting experience.
If your vehicle has continuously controlled
damping suspension it adjusts to a stiffer
suspension setting, with an emphasis on
handling and control. The transmission also
holds gears longer, helping your vehicle
accelerate faster when shifting gears.
If your vehicle has air suspension, it lowers
approximately
0.6 in (15 mm) to improve
aerodynamics. Normal
For everyday driving. This mode is a perfect
balance of excitement, comfort and
convenience. This is the default mode after
each ignition cycle.
Preserve EV
Your vehicle runs the engine as needed to
save electric driving range for later use in
another drive mode. For example, you first
drive at high speeds on open roads where
engine operation is appropriate. Later, you
drive at low speeds in an urban area where
electric only is most efficient.
See Plug-In
Hybrid Vehicle Operation (page 222).
Pure EV
This mode provides an electric only driving
experience. Your vehicle could accelerate
more slowly, and the top speed could
reduce. For more power, you can temporarily
enable your engine at any time by using one
of the following methods: •
Press and hold the folder button on the
steering wheel when viewing the pure
EV information screen. Your vehicle
enables the engine as needed, and
returns to pure EV after several seconds,
or when the vehicle no longer needs the
engine.
• Press the accelerator pedal fully. A
pop-up message appears. Press OK on
the steering wheel to activate as needed.
Your vehicle could enable the engine if
system conditions require it. An engine
enabled message displays if this occurs. See
Information Messages
(page 140).
Your engine could enable if the climate
control is in a defrost mode and the outside
temperature is cold. If the vehicle does not
need defrost, select a different climate
control mode to permit pure EV.
Your vehicle changes from pure EV mode to
normal mode when the vehicle electric range
is zero.
Note: When in pure EV mode, your vehicle
stays in this mode if there is all electric
driving range available and the system does
not fault.

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
Emergency Towing WARNING:
If your vehicle has a
steering wheel lock make sure the ignition
is in the accessory or on position when
being towed.
If your vehicle becomes inoperable without
access to wheel dollies or a vehicle transport
trailer, it can be flat-towed with all wheels on
the ground, regardless of the powertrain and
transmission configuration, under the
following conditions:
• Your vehicle is facing forward for towing
in a forward direction.
• Refer to the Manual Park Release
procedure. See Automatic Transmission
(page 245). Failing to do so could result
in damage to the transmission.
• Maximum speed is
35 mph (56 km/h).
• Maximum distance is
50 mi (80 km). Note:
If you are unsure of the vehicle ’s
configuration, contact an authorized dealer.

be limited. After driving through water and
as soon as it is safe to do so:
•
Lightly press the brake pedal to dry the
brakes and to check that they work.
• Check that the horn works.
• Check that the exterior lights work.
• Turn the steering wheel to check that the
steering power assist works. FLOOR MATS WARNING: Use a floor mat designed
to fit the footwell of your vehicle that does
not obstruct the pedal area. Failure to
follow this instruction could result in the
loss of control of your vehicle, personal
injury or death. WARNING:
Pedals that cannot move
freely can cause loss of vehicle control and
increase the risk of serious personal injury. WARNING:
Secure the floor mat to
both retention devices so that it cannot slip
out of position and interfere with the
pedals. Failure to follow this instruction
could result in the loss of control of your
vehicle, personal injury or death. WARNING:
Do not place additional
floor mats or any other covering on top of
the original floor mats. This could result in
the floor mat interfering with the operation
of the pedals. Failure to follow this
instruction could result in the loss of
control of your vehicle, personal injury or
death. WARNING:
Always make sure that
objects cannot fall into the driver foot well
while your vehicle is moving. Objects that
are loose can become trapped under the
pedals causing a loss of vehicle control. 349

Severe Climates
If you drive in extremely cold climates:
•
It may be necessary to increase the
coolant concentration above 50%.
• A coolant concentration of 60% provides
improved freeze point protection.
Coolant concentrations above 60%
decrease the overheat protection
characteristics of the coolant and may
cause engine damage.
If you drive in extremely hot climates:
• You can decrease the coolant
concentration to 40%.
• Coolant concentrations below 40%
decrease the freeze and corrosion
protection characteristics of the coolant
and may cause engine damage.
Vehicles driven year-round in non-extreme
climates should use prediluted coolant for
optimum cooling system and engine
protection. Coolant Change
At specific mileage intervals, as listed in the
scheduled maintenance information, the
coolant should be changed. Add prediluted
coolant approved to the correct specification.
See Capacities and Specifications (page
450).
Fail-Safe Cooling
Fail-safe cooling allows you to temporarily
drive your vehicle before any incremental
component damage occurs. The fail-safe
distance depends on ambient temperature,
vehicle load and terrain.
How Fail-Safe Cooling Works If the engine begins to overheat,
the coolant temperature gauge
moves toward the red zone:
A warning lamp illuminates and a
message may appear in the
information display.If the engine reaches a preset
over-temperature condition, the engine
automatically switches to alternating cylinder
operation. Each disabled cylinder acts as an
air pump and cools the engine.
When this occurs, your vehicle still operates,
however:
•
Engine power is limited.
• The air conditioning system turns off.
Continued operation increases the engine
temperature, causing the engine to
completely shut down. Your steering and
braking effort increases in this situation.
When the engine temperature cools, you can
re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage.
