istics indicated
Ú
page 252.
Special Additives
Do not use any type of additive with the
automatic transmission oil. The automatic
transmission oil is a product designed especially
for this vehicle and its performance may be
compromised through the use of further
additives. Frequency of Oil Changes
In normal vehicle operating conditions, it is not
necessary to change the transmission oil.
REPLACING THE BATTERY
If necessary, replace the battery with another
battery with the same specifications. It is advised
to contact an authorized dealer for replacement.

NOTE:
Each time the 12 Volt battery is reconnected,
cycle the steering wheel all the way to the left.
Then cycle the steering wheel all the way to the
right to allow the steering angle sensor to learn
the steering angle thresholds.
Follow the battery manufacturer's instructions for
maintenance.

NOTE:
It will not be possible to open the liftgate with a
key or by pushing the button in the passenger
compartment when the battery is disconnected. Always position the manual liftgate opening strap
on the liftgate lock before disconnecting the
battery. The procedure is described in the
“Liftgate Emergency Opening”

FUSES
General Information
The fuses protect electrical systems against
excessive current.
When a device does not work, you must check the
electrical circuit inside of the fuse for a break/
melt.
Also, please be aware that using power outlets for
extended periods of time with the engine off may
result in vehicle battery discharge.
Blade Fuses
To avoid contamination from foreign matter
or moisture, use only new brake fluid or fluid
that has been in a tightly closed container.
Keep the master cylinder reservoir cap
secured at all times. Brake fluid in an open
container absorbs moisture from the air
resulting in a lower boiling point. This may
cause it to boil unexpectedly during hard or
prolonged braking, resulting in sudden brake
failure. This could result in a collision.
Overfilling the brake fluid reservoir can result
in spilling brake fluid on hot engine parts,
causing the brake fluid to catch fire. Brake
fluid can also damage painted and vinyl
surfaces, care should be taken to avoid its
contact with these surfaces.
Do not allow petroleum-based fluid to
contaminate the brake fluid. Brake seal
components could be damaged, causing
partial or complete brake failure. This could
result in a collision.
WARNING! CAUTION!

Do not use chemical flushes in your
transmission as the chemicals can damage your
transmission components. Such damage is not
covered by the New Vehicle Limited Warranty.

CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe
transmission damage may occur. An
authorized dealer has the proper tools to
adjust the fluid level accurately.
