Ignition Modes
The keyless starting system has three
modes:
Off: Turns the ignition off.
• Without applying the brake pedal, press
and release the button once when the
ignition is in the on mode, or when your
vehicle is running but is not moving.
On:
All electrical circuits are operational and
the warning lamps and indicators illuminate.
• Without applying the brake pedal, press
and release the button once. Start:
Starts your vehicle. The engine may
not start when your vehicle starts.
• Press the brake pedal, and then press
the button for any length of time. An
indicator light on the button illuminates
when the ignition is on and when your
vehicle starts.
STARTING A GASOLINE ENGINE
When you start the engine, the idle speed
increases. This helps to warm up the
engine. If the engine idle speed does not
slow down, have your vehicle checked as
soon as possible. Note:
You can crank the engine for a total
of 60 seconds without the engine starting
before the starting system temporarily
disables. The 60 seconds does not have to
be all at once. For example, if you crank the
engine three times for 20 seconds each time,
without the engine starting, you reached the
60-second time limit. A message appears in
the information display alerting you that you
exceeded the cranking time. You cannot
attempt to start the engine for at least 15
minutes. After 15 minutes, you are limited to
a 15-second engine cranking time. You need
to wait 60 minutes before you can crank the
engine for 60 seconds again.
Before starting your vehicle, check the
following:
• Make sure all occupants have fastened
their seatbelts.
• Make sure the headlamps and electrical
accessories are off.
• Make sure the parking brake is on.
• Make sure the transmission is in park (P).
• Switch the ignition on.
Note: Do not touch the accelerator pedal.

EMISSION LAW
WARNING: Do not remove or alter
the original equipment floor covering or
insulation between it and the metal floor
of the vehicle. The floor covering and
insulation protect occupants of the vehicle
from the engine and exhaust system heat
and noise. On vehicles with no original
equipment floor covering insulation, do not
carry passengers in a manner that permits
prolonged skin contact with the metal floor.
Failure to follow these instructions may
result in fire or personal injury.
U.S. federal laws and certain state laws
prohibit removing or rendering inoperative
emission control system components. Similar
federal or provincial laws may apply in
Canada. We do not approve of any vehicle
modification without first determining
applicable laws. Tampering with emissions control
systems including related sensors
or the Diesel Exhaust Fluid system
can result in reduced engine power and the
illumination of the service engine soon light.
Tampering With a Noise Control
System
Federal laws prohibit the following acts:
• Removal or rendering inoperative by any
person other than for purposes of
maintenance.
• Repair or replacement of any device or
element of the design incorporated into
a new vehicle for the purpose of noise
control prior to its sale or delivery to the
ultimate purchaser or while it is in use.
• The use of the vehicle after any person
removes or renders inoperative any
device or element of the design. The U.S. Environmental Protection Agency
may presume to constitute tampering as
follows:
•
Removal of hood blanket, fender apron
absorbers, fender apron barriers,
underbody noise shields or acoustically
absorptive material.
• Tampering or rendering inoperative the
engine speed governor, to allow engine
speed to exceed manufacturer
specifications.
If the engine does not start, runs rough,
experiences a decrease in engine
performance, experiences excess fuel
consumption or produces excessive exhaust
smoke, check for the following:
• A plugged or disconnected air inlet
system hose.
• A plugged engine air filter element.
• Water in the fuel filter and water
separator.
• A clogged fuel filter.
• Contaminated fuel.
• Air in the fuel system, due to loose
connections.

GENERAL INFORMATION
Note:
Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out and an
authorized dealer should check them. If the
vehicle has continuous vibration or shudder
in the steering wheel while braking, an
authorized dealer should check your vehicle.
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. 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.
See Cleaning the Wheels (page 410). 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, have your vehicle towed
to the nearest authorized dealer.
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. If the light does not momentarily
illuminate, continues to flash or
remains on when you switch the
ignition on or apply the parking brake, the
anti-lock braking system could be disabled.
Have the system checked by an authorized
dealer. If the anti-lock brake system is
disabled, normal braking is still effective.
See
Warning Lamps and Indicators (page
129).
Note: Indicators vary depending on region. If the light does not momentarily
illuminate, continues to flash or
remains on when you switch the
ignition on or apply the parking
brake, have the system checked
by an authorized dealer. If the
brake warning lamp illuminates with the
parking brake released, have the system
checked immediately.

Hilly Condition Usage
You should select a lower gear when the
system is active in situations such as
prolonged downhill driving on steep grades,
for example in mountainous areas. The
system needs additional engine braking in
these situations to reduce the load on the
vehicle
’s regular brake system to prevent it
from overheating.
Note: An audible alarm sounds and the
system shuts down if it applies brakes for an
extended period of time. This allows the
brakes to cool. The system functions
normally again after the brakes cool.
ADAPTIVE CRUISE CONTROL
LIMITATIONS - VEHICLES WITH:
ADAPTIVE CRUISE CONTROL
WITH LANE CENTERING
Adaptive cruise control limitations apply to
lane centering unless stated otherwise or
contradicted by a lane centering limitation.
See Adaptive Cruise Control Limitations
(page 293). The system may not correctly operate in any
of the following conditions:
•
Your vehicle is not centered in the lane.
• The lane is too narrow or wide.
• The system does not detect at least one
lane marking or when lanes merge or
split.
• You switch the direction indicator on.
• Limited steering torque input is applied.
• Areas under construction or new
infrastructure.
• When modifications to the steering
system have been made.
• When using a spare tire.
Note: The driving assistance torque is limited
and may not be sufficient for all driving
situations such as driving through tight
curves or driving through curves at high
speeds.
Note: In exceptional conditions, the system
may deviate from the center line. ADAPTIVE CRUISE CONTROL

Trailer Lamps
WARNING: Never connect any trailer
lamp wiring to the vehicle's tail lamp wiring;
this may damage the electrical system
resulting in fire. Contact your authorized
dealer as soon as possible for assistance
in proper trailer tow wiring installation.
Additional electrical equipment may be
required.
Most towed vehicles require trailer lamps.
Make sure all running lights, brake lights,
direction indicators and hazard flashers are
working.
Before Towing a Trailer
Practice turning, stopping and backing up to
get the feel of your vehicle-trailer
combination before starting on a trip. When
turning, make wider turns so the trailer
wheels clear curbs and other obstacles. When Towing a Trailer
•
Do not drive faster than 70 mph
(113 km/h) during the first 500 mi
(800 km).
• Do not make full-throttle starts.
• Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly after
you have traveled
50 mi (80 km).
• When stopped in congested or heavy
traffic during hot weather, place the
gearshift in park (P) to aid engine and
transmission cooling and to help A/C
performance.
• Turn off the speed control with heavy
loads or in hilly terrain. The speed control
may turn off automatically when you are
towing on long, steep grades.
• Shift to a lower gear when driving down
a long or steep hill. Do not apply the
brakes continuously, as they may
overheat and become less effective. •
If your transmission is equipped with a
Grade Assist or Tow/Haul feature, use
this feature when towing. This provides
engine braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and transmission
cooling.
• Allow more distance for stopping with a
trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a grade. However, if
you must park on a grade:
1. Turn the steering wheel to point your vehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the automatic transmission in park
(P).
4. Place wheel chocks in front and back of the trailer wheels. (Chocks not included
with vehicle.)
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer
before
backing the trailer into the water.

Aviator (CTV) Canada/United States of America, enUSA, Edition date: 202007, Second-Printing Towing

•
Drive a heavily loaded vehicle or tow a
trailer.
• Carry unnecessary weight (approximately
1 mpg [0.4 km/L] is lost for every 400 lb
[180 kilogram] of weight carried).
• Driving with the wheels out of alignment.
Conditions
• Heavily loading a vehicle or towing a
trailer may reduce fuel economy at any
speed.
• Adding certain accessories to your
vehicle (for example bug deflectors,
rollbars, light bars, running boards, ski
racks or luggage racks) may reduce fuel
economy.
• To maximize the fuel economy, drive with
the tonneau cover installed (if equipped).
• Using fuel blended with alcohol may
lower fuel economy.
• Fuel economy may decrease with lower
temperatures during the first 5–10 mi
(12–16 km) of driving.
• Driving on flat terrain offers improved fuel
economy as compared to driving on hilly
terrain. •
Transmissions give their best fuel
economy when operated in the top cruise
gear and with steady pressure on the gas
pedal.
• Four-wheel-drive operation (if equipped)
is less fuel efficient than two-wheel-drive
operation.
COLD WEATHER PRECAUTIONS
The functional operation of some
components and systems can be affected at
temperatures below approximately
-13°F
(-25°C).
BREAKING-IN
You need to break in new tires for
approximately
300 mi (480 km). During this
time, your vehicle may exhibit some unusual
driving characteristics. DRIVING THROUGH WATER WARNING:
Do not drive through
flowing or deep water as you may lose
control of your vehicle.
Note: Driving through standing water can
cause vehicle damage.
Note: Engine damage can occur if water
enters the air filter.
Before driving through standing water, check
the depth. Never drive through water that is
higher than the bottom of the front rocker
area of your vehicle.
