PRECAUTIONS
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 vehicle off. After at least 10
seconds, switch the vehicle 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.
Adapt your speed and driving behavior
according to reduced steering assist.
Extreme continuous steering may increase
the effort to steer. This occurs to prevent
internal overheating and damage to the
steering system. If this occurs, you will not
lose the ability to steer your vehicle
manually nor will it cause damage to the
system. Normal steering and driving allows
the system to cool down and steering
assist returns to normal.
Note: There is no fluid reservoir to check or
fill. ELECTRIC POWER STEERING
ADAPTIVE STEERING
(If Equipped)
The adaptive steering system changes the
steering ratio with changes to vehicle
speed, optimizing the steering response in
all conditions. The system also changes
when you switch on the transmission
tow/haul feature. When you select the
tow/haul button, the adaptive steering
system reduces vehicle sensitivity to
steering inputs at higher vehicle speeds,
while maintaining the ease of parking and
maneuverability at low speeds.
Note: The adaptive steering system
continuously monitors for faults. If the
system detects a fault, a message appears
in the information display. If a red warning
message displays, stop your vehicle as soon
as it is safe to do so. The message could
clear if the fault is no longer present. If an
adaptive steering system warning message
appears each time you start your vehicle,
have the system checked as soon as
possible.
Note: The system has a locking device. It
remains mechanically locked at a fixed
steering ratio with the lock engaged. You
may notice a click when you turn your
vehicle on or off.
Note: If your vehicle loses electrical power
or detects a fault when you are driving, the
system shuts down and you retain a normal
steering function with a fixed steering ratio.
During this time, it is possible that the
steering wheel could not be straight when
the vehicle is driving straight ahead. In
addition, you could notice that the steering
wheel angle required to steer your vehicle
could be different.

Water alone, without engine coolant, can
cause engine damage from corrosion,
overheating or freezing.
Do not use the following as a coolant
substitute, as they can cause engine
damage from overheating or freezing:
•
Alcohol.
• Methanol.
• Brine.
• Any coolant mixed with alcohol or
methanol antifreeze.
Do not add extra inhibitors or additives to
the coolant. These can be harmful and
compromise the corrosion protection of
the coolant.
Severe Climates
If you drive in extremely cold climates, you
may need to increase the coolant
concentration above 50%.
Note: A coolant concentration of 60%
provides improved freeze point protection.
Coolant concentrations above 60%
decrease the overheat protection
characteristics of the coolant and could
cause engine damage.
If you drive in extremely hot climates, you
may need to decrease the coolant
concentration to 40%.
Note: A coolant concentration of 40%
provides improved overheat protection.
Coolant concentrations below 40%
decrease the overheat and corrosion
protection characteristics of the coolant and
could cause engine damage.
Coolant Change WARNING: Do not dispose of
coolant in the household refuse or the
public sewage system. Use an authorized
waste disposal facility. Change the coolant at specific mileage
intervals. Refer to the scheduled
maintenance information. See
Normal
Scheduled Maintenance (page 667).
Note: Dispose of used coolant in the
appropriate manner.
Follow your community's regulations and
standards for recycling and disposing of
automotive fluids.
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.
