Checking Oil Level — Gasoline Engine
To assure proper lubrication of your vehicle’s engine, the
engine oil must be maintained at the correct level. Check
the oil level at regular intervals, such as every fuel stop.
The best time to check the engine oil level is about five
minutes after a fully warmed up engine is shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Always
maintain the oil level within the SAFE zone on the dipstick.
Adding one quart of oil when the reading is at the bottom
of the SAFE zone will result in a reading at the top of the
safe zone on these engines.
CAUTION!
Overfilling or underfilling the crankcase will cause
aeration or loss of oil pressure. This could damage your
engine.
Adding Washer Fluid
The instrument cluster display will indicate when the
washer fluid level is low. When the sensor detects a low
fluid level, the windshield will light on the vehicle graphic
outline and the “WASHER FLUID LOW” message will be
displayed.The fluid reservoir for the windshield washers and the rear
window washer is shared. The fluid reservoir is located in
the engine compartment, be sure to check the fluid level at
regular intervals. Fill the reservoir with windshield washer
solvent only (not radiator antifreeze). When refilling the
washer fluid reservoir, take some washer fluid and apply it
to a cloth or towel and wipe clean the wiper blades, this
will help blade performance. To prevent freeze-up of your
windshield washer system in cold weather, select a solu-
tion or mixture that meets or exceeds the temperature
range of your climate. This rating information can be found
on most washer fluid containers.
WARNING!
Commercially available windshield washer solvents
are flammable. They could ignite and burn you. Care
must be exercised when filling or working around the
washer solution.
Maintenance-Free Battery
Your vehicle is equipped with a maintenance-free battery.
You will never have to add water, nor is periodic mainte-
nance required.

NOTE:
Press “Compass Calibration” on the touchscreen to enter calibration. To start calibration of the compass, press the
“Yes” button on the touchscreen and complete one or more 360-degree turns (in an area free from large metal or me-
tallic objects). A message will appear on the touchscreen when the compass has been successfully calibrated.
Keep magnetic materials away from the rear view mirror, such as Mobile Phones, Laptops and Radar Detectors. This
is where the compass module is located, and it can cause interference with the compass sensor, and it may give false
readings.
