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.
To maintain correct operation of the
battery management system, if you add
any electrical devices to your vehicle, do
not connect the ground connection directly
to the negative battery terminal. A
connection at the negative battery terminal
can cause inaccurate measurements of
the battery condition and potential
incorrect system operation.
Note: If you add electrical accessories or
components to your vehicle this may
adversely affect battery performance,
durability and the performance of other
electrical systems on your vehicle.
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. 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.
Note: After cleaning or replacing the
battery, make sure you reinstall the battery
cover or shield.
If you disconnect or replace the vehicle
battery, you must reset the following
features:
• Window bounce-back. See Window
Bounce-Back (page 162).
• Clock Settings.
• Pre-set radio stations.
• Steering Angle Sensor.

pressure sensors are mounted into
each tire on your trailer. The
sensors send a message to your
vehicle indicating the current
trailer tire pressure and
temperature.
If the trailer tire pressure
monitoring system detects that a
tire is low, a warning message
appears in the information display.
The trailer tire information screen
in the information display
highlights the tire with a low
pressure.
If the trailer tire pressure
monitoring system detects that a
tire temperature is over temp, a
warning message appears in the
Information display. The trailer tire
information screen in the
information display highlights the
tire with a high temperature.
The main function of the trailer tire
pressure monitoring system is to
warn you when your trailer tires
need air or if the tires are
experiencing high temperatures.
It can also warn you in the event
the system is no longer capable
of functioning as intended. See
Tire Pressure Monitoring
System – Information
Messages
(page 565). When a Temporary Spare or
New Tire is Installed
If you have replaced a trailer tire
with a new or spare tire, a warning
message appears and pressure
readings are no longer displayed
for that tire.
To restore the full function of the
trailer tire pressure monitoring
system:
•
Have the damaged wheel and
tire assembly repaired and
remounted to your trailer.
• Install the trailer tire pressure
monitoring sensor into the new
wheel and tire assembly.
• Perform the trailer tire pressure
monitoring system reset
procedure.
Trailer Tire Pressure
Monitoring System Reset
Procedure
Note: You need to perform the tire
pressure monitoring system reset
procedure after each tire rotation,
or when a new trailer tire pressure
sensor is installed into a trailer tire.
The trailer tire pressure monitoring
system can be reset through the
menu in the information display.
See Tire Pressure Monitoring
System – Information
Messages (page 565). Performing
the trailer setup process also
resets the trailer tire pressure
monitoring system.

It is important to rely upon your dealership
to properly diagnose and repair your
vehicle.
We strongly recommend only using our
genuine or our authorized re-manufactured
replacement parts engineered for your
vehicle.
Additives and Chemicals
We do not recommend using chemicals or
additives not approved by us as part of
your vehicle
’s normal maintenance. Please
consult your warranty information.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a
normal operating characteristic and, by
itself, does not necessarily indicate a
concern or that the fluid needs to be
changed. Have discolored fluids that also
show signs of overheating or foreign
material contamination checked
immediately. Make sure to change the vehicle
’s oils and
fluids at the specified intervals or in
conjunction with a repair. Flushing is a
viable way to change fluid for many vehicle
sub-systems during scheduled
maintenance. It is critical that systems are
flushed only with new fluid that is the same
as that required to fill and operate the
system or using our approved flushing
chemical.
Owner Checks and Services
Make sure you perform the following basic
maintenance checks and inspections. Check Every Month
The air filter restriction gauge. 1
The engine oil level.
