Possible Cause
Symptom
An irregular curb along the parking space prevents the system from corre\
ctly aligning
your vehicle.
Vehicles or objects bordering the space may not be correctly parked.
Your vehicle stopped too far past the parking space.
The tires may not be correctly installed or maintained. For example, not inflated correctly,
improper size, or of different sizes.
A repair or alteration changes the detection capabilities.
A parked vehicle has a high attachment. For example, a salt sprayer, snowplow or moving
truck bed.
The parking space length or position of parked objects changes after your vehicle passes
the space.
The temperature around your vehicle quickly changes. For example, driving from a
heated garage into the cold, or after leaving a car wash.

The system may apply the brakes to slow
the vehicle to the new set speed. The set
speed displays continuously in the
information display when the system is
active.
Canceling the Set Speed
Press and release the button or tap
the brake pedal.
The set speed does not erase.
Resuming the Set Speed Press and release the button.
Your vehicle speed returns to the previously
set speed and gap setting. The set speed
displays continuously in the information
display when the system is active.
Note: Only use resume if you are aware of
the set speed and intend to return to it.
Automatic Cancellation
Automatic cancellation can also occur when: •
The tires lose traction.
• You apply the parking brake.
Park Brake Application
Automatic parking brake application and
cancellation occurs if:
• You unbuckle the seatbelt and open the
door after you stop the vehicle.
• You hold the vehicle at a stop
continuously for more than three minutes.
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. Switching Adaptive Cruise Control Off Press and release the button when
the system is in standby mode, or
switch the ignition off.
Note: You erase the set speed and gap
setting when you switch the system off.
Detection Issues WARNING: On rare occasions,
detection issues can occur due to the road
infrastructures, for example bridges,
tunnels and safety barriers. In these cases,
the system may brake late or
unexpectedly. At all times, you are
responsible for controlling your vehicle,
supervising the system and intervening, if
required. WARNING:
If the system
malfunctions, have your vehicle checked
as soon as possible.

operation at Gross Vehicle Weight
Rating, not at Gross Combined Weight
Rating.) Separate functional brakes
should be used for safe control of towed
vehicles and for trailers where the Gross
Combined Weight of the towing vehicle
plus the trailer exceed the Gross Vehicle
Weight Rating of the towing vehicle.
The gross combined weight must never
exceed the Gross Combined Weight
Rating.
Note:
For trailer towing information
refer to the RV and Trailer Towing Guide
available at an authorized dealer. WARNING: Do not exceed the
GVWR or the GAWR specified on the
certification label. WARNING:
Do not use
replacement tires with lower load
carrying capacities than the original
tires because they may lower your
vehicle's GVWR and GAWR limitations.
Replacement tires with a higher limit
than the original tires do not increase
the GVWR and GAWR limitations. WARNING:
Exceeding any
vehicle weight rating can adversely
affect the performance and handling
of your vehicle, cause vehicle damage
and can result in the loss of control of
your vehicle, serious personal injury
or death.
Steps for determining the correct load
limit:
1. Locate the statement "The combined
weight of occupants and cargo
should never exceed XXX kg or XXX
lb." on your vehicle ’s placard. 2.
Determine the combined weight of
the driver and passengers that will
be riding in your vehicle.
3. Subtract the combined weight of the
driver and passengers from XXX kg
or XXX lb.
4. The resulting figure equals the available amount of cargo and
luggage load capacity. For example,
if the “XXX” amount equals 1,400 lb.
and there will be five 150 lb.
passengers in your vehicle, the
amount of available cargo and
luggage load capacity is 650 lb.
(1400-750 (5 x 150) = 650 lb.)
5. Determine the combined weight of
luggage and cargo being loaded on
the vehicle. That weight may not
safely exceed the available cargo
and luggage load capacity calculated
in Step 4.

TOWING A TRAILER
WARNING: Towing trailers
beyond the maximum recommended
gross trailer weight exceeds the limit
of your vehicle and could result in
engine damage, transmission damage,
structural damage, loss of vehicle
control, vehicle rollover and personal
injury. WARNING:
Do not exceed the
GVWR or the GAWR specified on the
certification label.
Note: See
Recommended Towing
Weights (page 327).
Your vehicle may have electrical items,
such as fuses or relays, related to
towing.
See Fuses (page 360). Your vehicle's load capacity designation
is by weight, not by volume, so you
cannot necessarily use all available
space when loading a vehicle or trailer.
Towing a trailer places an extra load on
your vehicle's engine, transmission, axle,
brakes, tires and suspension. Inspect
these components periodically during,
and after, any towing operation.
Load Placement
To help minimize how trailer movement
affects your vehicle when driving:
•
Load the heaviest items closest to
the trailer floor.
• Load the heaviest items centered
between the left and right side trailer
tires. •
Load the heaviest items above the
trailer axles or just slightly forward
toward the trailer tongue. Do not
allow the final trailer tongue weight
to go above or below 10-15% of the
loaded trailer weight.
• Select a ball mount with the correct
rise or drop and load capacity. When
both the loaded vehicle and trailer
are connected, the trailer frame
should be level, or slightly angled
down toward your vehicle, when
viewed from the side.
When driving with a trailer or payload, a
slight takeoff vibration or shudder may
be present due to the increased payload
weight. Additional information regarding
proper trailer loading and setting your
vehicle up for towing is located in
another chapter of this manual.
See
Load Limit (page 309).
You can also find information in the
RV
& Trailer Towing Guide available at your
authorized dealer, or online.

The gain setting sets the trailer brake
controller for the specific towing condition.
You should change the setting as towing
conditions change. Changes to towing
conditions include trailer load, vehicle load,
road conditions and weather.
The gain should be set to provide the
maximum trailer braking assistance while
making sure the trailer wheels do not lock
when using the brakes. Locked trailer wheels
may lead to trailer instability.
1.
Make sure the trailer brakes are in good
working condition, functioning normally
and properly adjusted. See your trailer
dealer if necessary.
2. Hook up the trailer and make the electrical connections according to the
trailer manufacturer's instructions.
3. When you plug in a trailer with electric or
electric-over-hydraulic brakes, a message
confirming connection appears in the
information display. 4.
Use the gain adjustment (+ and -) buttons
to increase or decrease the gain setting
to the desired starting point. A gain
setting of 6.0 is a good starting point for
heavier loads.
5. In a traffic-free environment, tow the trailer on a dry, level surface at a speed
of 20–25 mph (32–40 km/h) and
squeeze the manual control lever
completely.
6. If the trailer wheels lock up, indicated by
squealing tires, reduce the gain setting.
If the trailer wheels turn freely, increase
the gain setting. Repeat Steps 5 and 6
until the gain setting is at a point just
below trailer wheel lock-up. If towing a
heavier trailer, trailer wheel lock-up may
not be attainable even with the maximum
gain setting of 10.

Messages
Note: An authorized dealer can diagnose
the trailer brake controller to determine
exactly which trailer fault has occurred.
However, your warranty does not cover this
diagnosis if the fault is with the trailer. A message indicating a trailer brake module
fault may display in response to faults sensed
by the trailer brake controller, accompanied
by a single tone. If this message appears,
contact an authorized dealer as soon as
possible for diagnosis and repair. The
controller may still function, but performance
may be degraded.
A message indicating a trailer wiring fault
may display when there is a short circuit on
the electric brake output wire. If this message
displays, accompanied by a single tone, with
no trailer connected, the problem is with your
vehicle wiring between the trailer brake
controller and the 7-pin connector at the
bumper. If the message only displays with a
trailer connected, the problem is with the
trailer wiring. Consult your trailer dealer for
assistance. This can be a short to ground
(such as a chaffed wire), short to voltage
(such as a pulled pin on trailer emergency
breakaway battery) or the trailer brakes may
be drawing too much current.

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
transmission in park (P) to aid engine and
transmission cooling and to help A/C
performance.
• Turn off the speed control when carrying
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 has 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.
• If your vehicle has AdvanceTrac with
RSC, this system may turn on during
typical cornering maneuvers with a
heavily loaded trailer. This is normal.
Turning the corner at a slower speed
while towing may reduce this tendency.
• If your vehicle has Adaptive suspension,
you can select NORMAL or SPORT drive
control modes for better experience
when towing a trailer.
See Information
Displays (page 134). •
If you are towing a trailer frequently in
hot weather, hilly conditions, at the gross
combined weight rating (or any
combination of these factors), consider
refilling your rear axle with synthetic gear
lubricant (if the axle is not already filled
with it).
See Capacities and
Specifications (page 438).
• 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 transmission in park (P).
4. Place wheel chocks in the front and back
of the trailer wheels.
Note: Chocks are not included with your
vehicle.

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 166).
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.

REDUCED ENGINE PERFORMANCE
WARNING: If you continue to drive
your vehicle when the engine is
overheating, the engine could stop without
warning. Failure to follow this instruction
could result in the loss of control of your
vehicle.
If the engine coolant temperature gauge
needle moves to the upper limit position, the
engine is overheating.
See Gauges (page
127).
You must only drive your vehicle for a short
distance if the engine overheats. The
distance you can travel depends on ambient
temperature, vehicle load and terrain. The
engine continues to operate with limited
power for a short period of time.
If the engine temperature continues to rise,
the fuel supply to the engine reduces. The
air conditioning switches off and the engine
cooling fan operates continually. 1. Gradually reduce your speed and stop
your vehicle as soon as it is safe to do
so.
2. Immediately switch the engine off to prevent severe engine damage.
3. Wait for the engine to cool down.
4. Check the coolant level.
See Engine
Coolant Check (page 383).
5. Have your vehicle checked as soon as possible.
ECONOMICAL DRIVING
Fuel economy is affected by several things
such as how you drive, the conditions you
drive under and how you maintain your
vehicle.
There are some things to keep in mind that
may improve your fuel economy:
• Accelerate and slow down in a smooth,
moderate fashion.
• Drive at steady speeds.
• Anticipate stops; slowing down may
eliminate the need to stop. •
Combine errands and minimize
stop-and-go driving (When running
errands, go to the furthest destination
first and then work your way back home).
• Close the windows for high-speed
driving.
• Drive at reasonable speeds.
• Keep the tires properly inflated and use
only the recommended size.
• Use the recommended engine oil.
• Perform all regularly scheduled
maintenance.
There are also some things you may want to
avoid doing because they reduce your fuel
economy:
• Avoid sudden or hard accelerations.
• Avoid revving the engine before turning
off the car.
• Avoid long idle periods.
• Do not warm up your vehicle on cold
mornings.
• Reduce the use of air conditioning and
heat.
• Avoid using speed control in hilly terrain.

Navigator (TB9) Canada/United States of America, enUSA, First-Printing Driving Hints

•
Do not rest your foot on the brake pedal
while driving.
• Avoid carrying unnecessary weight.
• Avoid adding particular accessories to
your vehicle (e.g. bug deflectors,
rollbars/light bars, running boards, ski
racks).
• Avoid driving with the wheels out of
alignment.
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 wheel hubs. When driving through standing water, drive
very slowly and do not stop your vehicle.
Your brake performance and traction may
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.
