Lifting the Vehicle
{Warning
Lifting a vehicle can cause an
injury. The vehicle can slip off the
jack and roll over you or other
people. You and they could be
badly injured. Find a level place
to lift your vehicle. To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put the transmission inP (Park).
3. Turn off the engine.
To be even more certain the
vehicle will not move, put blocks
in front of and behind the wheels.
{Warning
Getting under a vehicle when it is
lifted on a jack is dangerous.
If the vehicle slips off the jack, (Continued)

Warning (Continued)
you could be badly injured or
killed. Never get under a vehicle
when it is supported only by
a jack.
{Warning
Raising the vehicle with the jack
improperly positioned can
damage the vehicle or the vehicle
may fall and cause injury to you
or others.
If a jack is used to lift the vehicle,
follow the instructions that came
with the jack, and be sure to use the
correct lifting points to avoid
damaging the vehicle.
Caution
Lifting the vehicle improperly can
damage it and result in costly
repairs not covered by the vehicle
warranty. To lift the vehicle
properly and prevent vehicle
damage: . Be sure to place a block or
pad between the jack and
the vehicle.
. Lift only in the areas shown
in the following illustrations.
For additional information, see
your dealer and the service
manual.
Caution
The front jack pads must not
contact the rocker panels, the
front fenders, or the floor pan.
If they do, damage may occur. Lifting from the Front
–Frame
Use only a service jack with a lifting
pad diameter of 64 mm (2.5 in) or
smaller, and thick enough to make
sure the jack does not contact the
vehicle body.
Position the service jack and lifting
pad under the frame rail shipping
slot reinforcement.

Engine Oil
To ensure proper engine
performance and long life, pay
careful attention to engine oil.
Follow these important steps:
.
Use engine oil approved to the
proper specification and of the
proper viscosity grade. See
“Selecting the Right Engine Oil”
later in this section. .
Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” later in this section.
. Change the engine oil at the
appropriate time. See Engine Oil
Life System 0221.
. Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking the Engine Oil
1. Engine Oil Dipstick
2. Engine Oil Fill Cap
Check the engine oil level regularly,
every 650 km (400 mi), especially
prior to a long trip. To get an
accurate reading, the vehicle must
be parked on a level ground.
The engine oil dipstick handle is a
loop. See Engine Compartment
Overview 0215 for the location.
The vehicle has a racetrack-ready
dry sump engine lubrication system.
This high performance system
operates differently than a standard
engine lubrication system and
requires a special procedure when
checking the engine oil level. Follow
this procedure closely.
The engine oil level must be
checked when the engine is warm.
Cold oil level in the dry sump tank
may not indicate the actual amount
of oil in the system. Engine oil is
contained in an external tank,
separate from the engine. Under
normal operating conditions, the oil
pan under the engine does not store
any oil. If the vehicle has been
parked for an extended period
without the engine being started,
some oil will seep back into the oil

12470550) - 2020 - CRC - 4/23/20
Vehicle Care 219
pan. This will reduce the amount of
oil held in the dry sump tank and
there could be no engine oil on the
dipstick. This is normal since the
dipstick is designed to read the
engine oil level only after the engine
has run long enough to reach
normal operating temperature. Do
not add engine oil based on cold
engine dipstick readings. The
engine oil level on the dipstick must
be checked while the engine is
running at idle.
To check the engine oil:1. Turn the engine on and let it warm up to at least 80 °C (175
°F).
2. Once the engine is warm, check the oil while the engine
is running at idle.
{Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle. 3. Remove the dipstick and wipe
it with a clean lint-free paper
towel or a cloth. Re-insert the
dipstick and push it all the way
in until it stops.
4. Remove the dipstick again and read the level on the
cross-hatched area.
5. Turn the engine off.
When to Add Engine Oil
If the oil is below the cross-hatched
area at the tip of the dipstick, add
1 L (1 qt) of the recommended oil
through the oil fill cap opening in the
oil tank fill tube and then recheck
the level. See “Selecting the Right
Engine Oil” later in this section for
the type of oil to use. For engine oil
crankcase capacity, see Capacities
and Specifications 0299.
Caution
Do not add too much oil. Oil
levels above or below the
acceptable operating range
shown on the dipstick are harmful
to the engine. If the oil level is
above the operating range (i.e.,
the engine has so much oil that
the oil level gets above the
cross-hatched area that shows
the proper operating range), the
engine could be damaged. Drain
the excess oil or limit driving of
the vehicle, and seek a service
professional to remove the
excess oil.
See Engine Compartment Overview
0 215 for the location of the external
engine oil tank dipstick and fill cap.
Add enough oil to put the level
somewhere in the proper operating
range. Push the dipstick all the way
back into the oil tank tube when
finished.
