Maintenance

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.
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.

Maintenance

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.
WARNING: Only use brake fluid from
a sealed container. Contamination with dirt,
water, petroleum products or other
materials may result in brake system
damage or failure. Failure to adhere to this
warning could result in the loss of vehicle
control, serious personal injury or death.
WARNING: Do not allow the fluid to
touch your skin or eyes. If this happens,
rinse the affected areas immediately with
plenty of water and contact your physician.
WARNING: The brake system could
be affected if the brake fluid level is below
the MIN mark or above the MAX mark on
the brake fluid reservoir.
E170684
1. Park your vehicle on a level surface.
2. Look at the brake fluid reservoir to see
where the brake fluid level is relative to
the MIN and the MAX marks on the
reservoir.
Note:If the brake fluid level is between the
MIN and the MAX marks on the reservoir, it
is acceptable.Note:If the brake fluid level is below the MIN
mark or above the MAX mark, have your
vehicle checked as soon as possible.
Note:To avoid fluid contamination, the
reservoir cap must remain in place and fully
tight, unless you are adding fluid.
Only use fluid that meets our specifications.
See Capacities and Specifications (page
460).
Brake Fluid Service Interval
Brake fluid absorbs water over time which
degrades the effectiveness of the brake fluid.
Change the brake fluid at the specified
intervals to prevent degraded braking
performance.
For detailed interval information, see
Scheduled Maintenance in your Owner's
Manual or your local maintenance guide.
POWER STEERING FLUID CHECK
Your vehicle is equipped with an electric
power steering (EPS) system. There is no
fluid reservoir to check or fill.

Maintenance

For longer, trouble-free operation, keep the
top of the battery clean and dry and the
battery cables tightly fastened to the battery
terminals. If any corrosion is present on the
battery or terminals, remove the cables from
the terminals and clean with a wire brush.
You can neutralize the acid with a solution
of baking soda and water.
We recommend that you disconnect the
negative battery cable terminal from the
battery if you plan to store your vehicle for
an extended period.
Note:If you only disconnect the negative
battery cable terminal, make sure it is
isolated or placed away from the battery
terminal to avoid unintended connection or
arcing.
If you replace the battery make sure it
matches the electrical requirements of your
vehicle.If you disconnect or replace the battery and
your vehicle has an automatic transmission,
it must relearn its adaptive strategy. Because
of this, the transmission may shift firmly when
first driven. This is normal operation while
the transmission fully updates its operation
to optimum shift feel.
Battery Sensor Reset
When you install a new battery, reset the
battery sensor by doing the following:
1. Switch the ignition on, and leave the
engine off.
Note:Complete Steps 2 and 3 within 10
seconds.
2. Flash the high beam headlamps five
times, ending with the high beams off.
3. Press and release the brake pedal three
times.
The battery warning lamp flashes three times
to confirm that the reset is successful.
Battery Management System (If Equipped)
The system monitors battery conditions and
takes actions to extend battery life. If
excessive battery drain is detected, the
system temporarily disables some electrical
systems to protect the battery.
Systems included are:
• Heated rear window.
• Heated seats.
• Climate control.
• Heated steering wheel.
• Audio unit.
• Navigation system.
A message may appear in the information
display to alert you that battery protection
actions are active. This message is only for
notification that an action is taking place, and
not intended to indicate an electrical problem
or that the battery requires replacement.

notification that an action is taking place, and
not intended to indicate an electrical problem
or that the battery requires replacement.After battery replacement, or in some cases
after charging the battery with an external
charger, the battery management system
requires eight hours of vehicle sleep time to
relearn the battery state of charge. During
this time, your vehicle must remain fully
locked with the ignition switched off.
Note:Prior to relearning the battery state of
charge, the battery management system
may temporarily disable some electrical
systems.
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
Install a battery approved for use by our
specifications. See Capacities and
Specifications (page 460).
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 the system to
store diagnostic and adaptive tables.
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.
