When Fail-Safe Mode Is Activated
WARNING: Fail-safe mode is for use
during emergencies only. Operate your
vehicle in fail-safe mode only as long as
necessary to bring your vehicle to rest in
a safe location and seek immediate repairs.
When in fail-safe mode, your vehicle will
have limited power, will not be able to
maintain high-speed operation, and may
completely shut down without warning,
potentially losing engine power, power
steering assist, and power brake assist,
which may increase the possibility of a
crash resulting in serious injury. WARNING: Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap with
a thick cloth to prevent the possibility of
scalding and slowly remove the cap.
Failure to follow this instruction could result
in personal injury. Your vehicle has limited engine power when
in the fail-safe mode, drive your vehicle with
caution. Your vehicle does not maintain
high-speed operation and the engine may
operate poorly.
Remember that the engine is capable of
automatically shutting down to prevent
engine damage. In this situation:
1. Pull off the road as soon as safely
possible and switch the engine off.
2. If you are a member of a roadside assistance program, we recommend that
you contact your roadside assistance
service provider.
3. If this is not possible, wait for a short period of time for the engine to cool.
4. Check the coolant level. If the coolant level is at or below the minimum mark,
add prediluted coolant immediately.
5. When the engine temperature cools, you
can re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage.
Note: Driving your vehicle without repair
increases the chance of engine damage. Engine Coolant Temperature
Management
(If Equipped) WARNING:
To reduce the risk of
crash and injury, be prepared that the
vehicle speed may reduce and the vehicle
may not be able to accelerate with full
power until the coolant temperature
reduces.
If you tow a trailer with your vehicle, the
engine may temporarily reach a higher
temperature during severe operating
conditions, for example ascending a long or
steep grade in high ambient temperatures.
At this time, you may notice the coolant
temperature gauge moves toward the red
zone and a message may appear in the
information display.

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

You may notice a reduction in vehicle speed
caused by reduced engine power in order
to manage the engine coolant temperature.
Your vehicle may enter this mode if certain
high-temperature and high-load conditions
take place. The amount of speed reduction
depends on vehicle loading, grade and
ambient temperature. If this occurs, there is
no need to stop your vehicle. You can
continue to drive.
The air conditioning may automatically turn
on and off during severe operating
conditions to protect the engine from
overheating. When the coolant temperature
decreases to the normal operating
temperature, the air conditioning turns on.
If the coolant temperature gauge moves fully
into the red zone, or if the coolant
temperature warning or service engine soon
messages appear in your information display,
do the following:
1.
Stop your vehicle as soon as it is safe to
do so. Fully apply the parking brake, shift
into park (P) or neutral (N). 2. Leave the engine running until the
coolant temperature gauge needle
returns to the normal position. If the
temperature does not drop after several
minutes, follow the remaining steps.
3. Switch the engine off and wait for it to cool. Check the coolant level.
4. If the coolant level is at or below the minimum mark, add prediluted coolant
immediately.
5. If the coolant level is normal, restart the engine and continue.
AUTOMATIC TRANSMISSION
FLUID CHECK
If required, have an authorized dealer check
and change the transmission fluid at the
correct service interval. See Scheduled
Maintenance (page 564).
The automatic transmission does not have
a transmission fluid dipstick. Refer to your scheduled maintenance
information for scheduled intervals for fluid
checks and changes. Your transmission does
not consume fluid. However, if the
transmission slips, shifts slowly or if you
notice a sign of leaking fluid, contact an
authorized dealer.
Do not use supplemental transmission fluid
additives, treatments or cleaning agents. The
use of these materials may affect
transmission operation and result in damage
to internal transmission components.
BRAKE FLUID CHECK
WARNING: Do not use any fluid other
than the recommended brake fluid as this
will reduce brake efficiency. Use of
incorrect fluid could result in the loss of
vehicle control, serious personal injury or
death.

Electrical Accessory Installation
To make sure the battery management
system works correctly, do not connect an
electrical device ground connection directly
to the battery negative post. This can cause
inaccurate measurements of the battery
condition and potential incorrect system
operation.
Note:
If you add electrical accessories or
components to the vehicle, it may adversely
affect battery performance and durability.
This may also affect the performance of
other electrical systems in the vehicle.
Remove and Reinstall the Battery
To disconnect or remove the battery, do the
following:
1. Apply the parking brake and switch the ignition off.
2. Switch all electrical equipment off, for example lights and radio.
3. Wait a minimum of two minutes before disconnecting the battery. Note:
The engine management system has
a power hold function and remains powered
for a period of time after you switch the
ignition off. This is to allow diagnostic and
adaptive tables to be stored. Disconnecting
the battery without waiting can cause
damage not covered by the vehicle
Warranty.
4. Disconnect the negative battery cable terminal.
5. Disconnect the positive battery cable terminal.
6. Remove the battery securing clamp.
7. Remove the battery.
8. To install, reverse the removal procedure.
Note: Before reconnecting the battery, make
sure the ignition remains switched off.
Note: Make sure the battery cable terminals
are fully tightened. If you disconnect or replace the vehicle
battery, you must reset the following
features:
•
Window bounce-back. See Power
Windows (page 119).
• Clock Settings.
• Pre-set radio stations.
Battery Disposal Make sure that you dispose of old
batteries in an environmentally
friendly way. Seek advice from
your local authority about recycling old
batteries.

GENERAL INFORMATION
The recommended tire inflation pressures
are found on the Tire Label which is located
on the B-pillar or the edge of the driver door.
This information can also be found 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’
s 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. Use only approved wheels and tire sizes,
using other sizes could damage your vehicle.
The tires installed on your vehicle from us
as original equipment are certified for
Greenhouse Gas and Fuel Efficiency
regulations. Replacement tires must be of
equal or lower rolling resistance level (TRRL
or CRR). Consult with your tire supplier for
appropriate replacement tires.
If you change the diameter of the factory
installed tires, the speedometer may not
display the correct speed. This could effect
the functionality of the All Wheel Drive (AWD)
system, if equipped. Take your vehicle to an
authorized dealer and have the engine
management system reprogrammed.
If you intend to change the size of the factory
installed tires, check the suitability with an
authorized dealer.
Additional information related to the
functionality and maintenance of your tires
can be found in the Wheels and Tire section.
See Tire Care (page 415).
Notice to utility vehicle and truck
owners 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.
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.

Tire Change Procedure WARNING: The jack supplied with
this vehicle is only intended for changing
wheels. Do not use the vehicle jack other
than when you are changing a wheel in an
emergency. WARNING:
Check that the vehicle
jack is not damaged or deformed and the
thread is lubricated and clean. WARNING:
When one of the front
wheels is off the ground, the transmission
alone will not prevent the vehicle from
moving or slipping off the jack, even if the
transmission is in park (P). WARNING:
To help prevent your
vehicle from moving when changing a
wheel, shift the transmission into park (P),
set the parking brake and use an
appropriate block or wheel chock to
secure the wheel diagonally opposite to
the wheel being changed. For example,
when changing the front left wheel, place
an appropriate block or wheel chock on
the right rear wheel. WARNING:
Always use the jack
provided as original equipment with your
vehicle. If using a jack other than the one
provided, make sure the jack capacity is
adequate for the vehicle weight, including
any vehicle cargo or modifications. If you
are unsure if the jack capacity is adequate,
contact the authorized dealer. WARNING:
Failure to follow these
guidelines could result in an increased risk
of loss of vehicle control, injury or death. WARNING:
Use only the specified
jacking points. If you use other positions,
you may damage the body, steering,
suspension, engine, braking system or the
fuel lines. WARNING:
Do not work on your
vehicle when the jack is the only support.
If the vehicle slips off the jack, you or
someone else could be seriously injured. WARNING:
Never place anything
between the vehicle jack and your vehicle.
