Checking Engine Oil
It is a good idea to check the engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 5-12for
the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If you do not do this,
the oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towel
or cloth, then push it back in all the way. Remove it
again, keeping the tip down, and check the level.
When to Add Engine Oil
If the oil is below the MIN (minimum) mark, add
at least one quart/liter of the recommended oil.
5-15

If you have to add coolant more than four times a year,
have your dealer/retailer check your cooling system.
Notice:If you use extra inhibitors and/or additives
in your vehicle’s cooling system, you could
damage your vehicle. Use only the proper mixture
of the engine coolant listed in this manual for
the cooling system. SeeRecommended Fluids and
Lubricants on page 6-12for more information.
Checking Coolant
The coolant recovery tank
cap has this symbol on it.
The tank is located in
the engine compartment
toward the front of the
engine on the passenger’s
side of the vehicle.
SeeEngine Compartment Overview on page 5-12for
more information on location.
The vehicle must be on a level surface when checking
the coolant level.When the engine is cold, the coolant level should be at
the COLD FILL (A) line or a little higher. The COLD
FILL line is near the bottom of the tank and sticks out
from the rear of the tank.
5-25

{CAUTION:
An electric engine cooling fan under the hood
can start up even when the engine is not
running and can injure you. Keep hands,
clothing, and tools away from any underhood
electric fan.
If the coolant inside the coolant recovery tank is
boiling, do not do anything else until it cools down.
The vehicle should be parked on a level surface.
When the engine is cold, the coolant level should be at
or above the COLD FILL line. If it is not, you may
have a leak at the pressure cap or in the radiator hoses,
heater hoses, radiator, water pump, or somewhere in
the cooling system.
{CAUTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Do not touch them.
If you do, you can be burned.
Do not run the engine if there is a leak. If you
run the engine, it could lose all coolant.
That could cause an engine re, and you could
be burned. Get any leak xed before you drive
the vehicle.
If there seems to be no leak, with the engine on, check
to see if the electric engine cooling fan is running.
If the engine is overheating, the fan should be running.
If it is not, than the vehicle needs service.
Notice:Engine damage from running the engine
without coolant is not covered by the warranty.
Notice:Using coolant other than DEX-COOL
®may
cause premature engine, heater core, or radiator
corrosion. In addition, the engine coolant could
require changing sooner, at 30,000 miles (50 000 km)
or 24 months, whichever occurs rst. Any repairs
would not be covered by the warranty. Always use
DEX-COOL
®(silicate-free) coolant in the vehicle.
5-29

How to Add Coolant to the
Cooling System
Notice:The engine has a specic cooling system
drain and ll procedure. Failure to follow this
procedure could cause the engine to overheat and
be severely damaged. If the engine’s cooling system
needs to be drained and re-lled, please see the
dealer/retailer.
If no problem is found, but the coolant level in the
coolant recovery tank is below the COLD FILL line,
add a 50/50 mixture of clean, drinkable water and
DEX-COOL
®engine coolant at the coolant recovery
tank. SeeEngine Coolant on page 5-24for more
information.If no coolant is visible in the coolant recovery tank, add
coolant at the pressure cap as follows:
{CAUTION:
Steam and scalding liquids from a hot cooling
system can blow out and burn you badly.
They are under pressure, and if you turn the
pressure cap — even a little — they can come
out at high speed. Never turn the cap when the
cooling system, including the pressure cap, is
hot. Wait for the cooling system and pressure
cap to cool if you ever have to turn the
pressure cap.
5-30

3. Add the proper DEX-COOL®coolant mixture to
the coolant ll port, up to the base of the port.
SeeEngine Coolant on page 5-24for more
information about the proper coolant mixture.
4. Rinse or wipe any spilled coolant from the engine
and the compartment.
5. Then ll the coolant recovery tank to the COLD
FILL (A) line.6. Put the cap back on the coolant recovery tank, but
leave the pressure cap off.
7. Start the engine and let it run until you can feel the
upper radiator hose getting hot. Watch out for the
engine cooling fan.
8. By this time, the coolant level inside the radiator
ller port may be lower. If the level is lower, add
more of the proper DEX-COOL
®coolant mixture
through the ll port until the level reaches the base
of the ll port.
9. Then replace the pressure cap. At any time during
this procedure, if coolant begins to ow out of the
ll port, reinstall the pressure cap. Be sure the
pressure cap is hand-tight and fully seated.
10. When the engine has cooled, check the coolant in
the coolant recovery tank. The level in the coolant
recovery tank should be at the COLD FILL line
when the engine is cold.

checks and services.
Be sure any necessary repairs are completed at once.
Whenever any uids or lubricants are added to your
vehicle, make sure they are the proper ones, as shown
inRecommended Fluids and Lubricants on page 6-12.
At Each Fuel Fill
It is important to perform these underhood checks at
each fuel fill.

regularly and keep it at the proper level. Failure to
keep the engine oil at the proper level can cause
damage to the engine not covered by your warranty.
Check the engine oil level and add the proper oil if
necessary. SeeEngine Oil on page 5-15.

2. Firmly apply both the parking brake and the regular
brake. SeeParking Brake on page 2-33.
Do not use the accelerator pedal, and be ready to
turn off the engine immediately if it starts.
3. On automatic transmission vehicles, try to start the
engine in each gear. The vehicle should start only
in PARK (P) or NEUTRAL (N). If the vehicle
starts in any other position, contact your
dealer/retailer for service.
