Changing rear window wiper blade
The rear wiper arm is designed without a service position. This reduces
the risk of damage to the blade in an automatic car wash.
To replace the wiper blade:
1. Grab the wiper arm with one
hand close to the arm/blade joint
and pull it as far away from the
glass as possible. Do not use
excessive force because it can break
the wiper arm at the heel. Hold it
there until the next step.
2. Grab the primary structure of the
blade with the other hand close to
the arm/blade joint.
3. Grip tightly and push on the arm/blade joint from beneath and
separate the blade from the arm.
4. Attach the new wiper to the
wiper arm and press it into place
until a click is heard.
If you find this procedure too
difficult, please see your dealer.

5. Locate and carefully remove the engine oil level dipstick.
6. Wipe the dipstick clean. Insert the dipstick fully, then remove it again.
•If the oil level is within the lower and upper holes/lines, the oil level is
acceptable.DO NOT ADD OIL.
•If the oil level is below the lower hole/line, engineoil must be added
to raise the level within the normal operating range.
•If required, add engine oil to the engine. Refer toAdding engine oil
in this chapter.
•Do not overfill the engine with oil. Oil levels above the upper
hole/line may cause engine damage.If the engine is overfilled,
some oil must be removed from the engine by an authorized dealer.
7. Put the dipstick back in and ensure it is fully seated.
Adding engine oil
1. Check the engine oil. For instructions, refer toChecking the engine
oilin this chapter.
2. If the engine oil level is not within the normal range, add only certified

Checking motor/electronics (M/E) coolant
The M/E coolant reservoir is located
behind the engine coolant reservoir.
Refer to the following engine
coolant sections for all information,
instructions and warnings related to
cooling systems. The two systems
use the same coolant and operate
similarly, with the Motor and
Electronics system generally
operating at a lower temperature
and pressure. The fluid levels in
both reservoirs need to be
maintained. When the engine is
cold, check the level of M/E coolant
in the reservoir.
Factory fill and coolant specifications
Your vehicle was factory-filled with a 50/50 engine coolant and water
concentration. If the concentration of coolant falls below 40% or above
60%, the engine parts could become damaged or not work properly.A
50–50 mixture of coolant and water provides the following:
•Freeze protection down to -34°F (-36°C).
•Boiling protection up to 265°F (129°C).
•Protection against rust and other forms of corrosion.
•Enables calibrated gauges to work properly.
Common instructions for cooling systems
•The engine coolant should be at the “FULL COLD” level or within the
“COLD FILL RANGE” as listed on the engine coolant reservoir
(depending upon application).
•Refer to thescheduled maintenance informationfor service interval
schedules.
•Be sure to read and understandPrecautions when servicing your
vehiclein this chapter.
