Checking the Engine Oil Level
1. Make sure that your vehicle is on level ground.
2. Check the oil level before starting the engine, or switch the engine off after
warming up and wait 10 minutes for the
oil to drain into the oil pan. 3. Remove the dipstick and wipe it with a
clean, lint-free cloth.
4. Reinstall the dipstick and make sure it is
fully seated.
5. Remove the dipstick again to check the oil level.
Note: If the oil level is between the maximum
and minimum marks, the oil level is
acceptable. Do not add oil.
6. If the oil level is at the minimum mark, immediately add oil.
7. Reinstall the dipstick. Make sure it is fully
seated.
Note: The oil consumption of new engines
reaches its normal level after approximately
3,000 mi (5,000 km).
Adding Engine Oil WARNING:
Do not remove the filler
cap when the engine is running.

Hybrid Battery Systems
We recommend the following actions for your
vehicle:
•
When storing your vehicle for greater
than 30 days the state of charge should
be approximately 50%. Additionally we
recommend disconnecting the 12V
battery which will reduce system loads
on the HV battery.
12 Volt Battery
• Check and recharge as necessary. Keep
connections clean.
Note: It is necessary to reset memory
features if you disconnect the battery cables.
Brakes
Make sure the brakes and parking brake
release fully.
Note: If you intend on parking your vehicle
for an extended period after cleaning the
wheels with a wheel cleaner, drive your
vehicle for a few minutes before doing so to
reduce the risk of increased corrosion of the
brake discs, brake pads and linings. Tires
•
Maintain recommended air pressure.
Note: If you intend on parking your vehicle
for an extended period after cleaning the
wheels with a wheel cleaner, drive your
vehicle for a few minutes before doing so.
This reduces the risk of corrosion of the
brake discs, brake pads and linings.
REMOVING YOUR VEHICLE FROM
STORAGE
When your vehicle is ready to come out of
storage, do the following:
• We recommend that you change the
engine oil before you use your vehicle
again.
• Wash your vehicle to remove any dirt or
grease film build-up on window surfaces.
• Check windshield wipers for any
deterioration.
• Check under the hood for any foreign
material that may have collected during
storage such as mice or squirrel nests. •
Check the exhaust for any foreign
material that may have collected during
storage.
• Check tire pressures and set tire inflation
per the Tire Label.
• Check brake pedal operation. Drive your
vehicle 15 ft (4.5 m) back and forth to
remove rust build-up.
• Check fluid levels (including coolant, oil
and gas) to make sure there are no leaks,
and fluids are at recommended levels.
• If you remove the battery, clean the
battery cable ends and check for
damage.
Contact an authorized dealer if you have any
concerns or issues.

If your information display resets prematurely
or becomes inoperative, you should perform
the oil change interval at six months or
5,000 mi (8,000 km) from your last oil
change. Never exceed one year or 10,000 mi
(16,000 km)
between oil change intervals.
You can drive high performance vehicles in
such a way that may lead to higher oil
consumption including extended time at high
engine speeds, high loads, engine braking,
hard cornering maneuvers, track and off-road
usage. Under these conditions, oil
consumption of approximately 1 quart per
500 miles (1 liter per 800 km) is possible.
Check the engine oil level at every refueling
and adjust to maintain proper levels to avoid
engine damage.
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

Be sure to ask your dealership service
advisor or technician about the multi-point
vehicle inspection. It is a comprehensive way
to perform a thorough inspection of your
vehicle. Your checklist gives you immediate
feedback on the overall condition of your
vehicle. NORMAL SCHEDULED
MAINTENANCE
Oil Change Reminder
Your vehicle comes with an oil change
reminder that determines when you should
change the engine oil based on how you use
your vehicle.Your vehicle lets you know when an oil
change is due by displaying a message in
the information display.
The following table provides examples of
vehicle use and its impact on oil change
intervals. It is a guideline only. Actual oil
change intervals depend on several factors
and generally decrease with severity of use.
