Maintenance  
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.  
CHANGING THE 12V BATTERY  
WARNING: Batteries normally  
produce explosive gases which can  
cause personal injury. Therefore, do not  
allow flames, sparks or lighted  
E170684  
substances to come near the battery.  
When working near the battery, always  
shield your face and protect your eyes.  
Always provide correct ventilation.  
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.  
WARNING: When lifting a  
plastic-cased battery, excessive pressure  
on the end walls could cause acid to flow  
through the vent caps, resulting in  
personal injury and damage to the  
vehicle or battery. Lift the battery with a  
battery carrier or with your hands on  
opposite corners.  
WARNING: Keep batteries out of  
reach of children. Batteries contain  
sulfuric acid. Avoid contact with skin,  
eyes or clothing. Shield your eyes when  
working near the battery to protect  
against possible splashing of acid  
solution. In case of acid contact with skin  
or eyes, flush immediately with water for  
a minimum of 15 minutes and get prompt  
medical attention. If acid is swallowed,  
call a physician immediately.  
Only use fluid that meets our  
specifications. See Capacities and  
Specifications (page 385).  
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.

Maintenance  
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.  
WARNING: Battery posts,  
terminals and related accessories  
contain lead and lead compounds,  
chemicals known to the State of  
California to cause cancer and  
reproductive harm. Wash your hands  
after handling.  
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.  
WARNING: This vehicle may have  
more than one battery. Removing the  
battery cables from only one battery  
does not disconnect your vehicle  
electrical system. Make sure you  
disconnect the battery cables from all  
batteries when disconnecting power.  
Failure to do so may cause serious  
personal injury or property damage.  
Battery Management System (If  
Equipped)  
WARNING: For vehicles with  
Auto-Start-Stop the battery requirement  
is different. You must replace the battery  
with one of exactly the same  
specification.  
The battery management 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.  
The battery is in the engine compartment.  
See Under Hood Overview (page 323).  
Systems included are:  
Your vehicle has a maintenance-free  
battery. It does not require additional  
water during service.  
If the vehicle battery has a cover and vent  
hose, make sure you correctly install it after  
cleaning or replacing the battery.  
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.  
Heated rear window.  
Heated seats.  
Climate control.

Audio unit.  
Navigation system.  
A message may appear in the information  
displays to alert you that battery  
protection actions are active. These  
messages are only for notification that an  
action is taking place, and not intended to  
indicate an electrical problem or that the  
battery requires replacement.  
We recommend that you disconnect the  
negative battery cable terminal from the  
battery if you plan to store your vehicle for  
an extended period.

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.  
5. Disconnect the positive battery cable  
terminal.  
6. Remove the battery securing clamp.  
7. Remove the battery.  
Note: Prior to relearning the battery state  
of charge, the battery management system  
may temporarily disable some electrical  
systems.  
8. To install, reverse the removal  
procedure.  
Note: Before reconnecting the battery,  
make sure the ignition remains switched off.  
Electrical Accessory Installation  
Note: Make sure the battery cable terminals  
are fully tightened.  
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.  
If you disconnect or replace the vehicle  
battery, you must reset the following  
features:  
Window bounce-back. See Power  
Windows (page 96).
