ENGINE OIL CHECK

To check the engine oil level consistently
and accurately, do the following:

1. Make sure the parking brake is on. Make

sure the transmission is in park (P) or
neutral (N).

2. Run the engine until it reaches normal

operating temperature.

3. Make sure that your vehicle is on level

ground.

4. Switch the engine off and wait 15 minutes

for the oil to drain into the oil pan. 
Checking the engine oil level too soon
after you switch the engine off may result
in an inaccurate reading.

5. Open the hood.   See Opening and

Closing the Hood (page 286).

6. Remove the dipstick and wipe it with a

clean, lint-free cloth.   See Under Hood
Overview (page 288).

7. Replace the dipstick and remove it again

to check the oil level.   See Under Hood
Overview (page 288).

8. Make sure that the oil level is between

the maximum and minimum marks. If the
oil level is at the minimum mark, add oil
immediately.   See Capacities and
Specifications (page 359).

9. If the oil level is correct, replace the

dipstick and make sure it is fully seated.

Note: Do not remove the dipstick when the
engine is running.

Note:  If the oil level is between the
maximum and minimum marks, the oil level
is acceptable.  Do not add oil.

Note: The oil consumption of new engines
reaches its normal level after approximately
3,000 mi (5,000 km).

ENGINE COOLANT CHECK

WARNINGS

Do not remove the coolant reservoir
cap when the cooling system is hot.

Wait 10 minutes for the cooling system to
cool down. Cover the coolant reservoir cap
with a thick cloth to prevent the possibility
of scalding and slowly remove the cap.
Failure to follow this instruction could result
in personal injury.

Do not put coolant in the windshield
washer reservoir. If sprayed on the

windshield, coolant could make it difficult to
see through the windshield.

WARNINGS

To reduce the risk of personal injury,
make sure the engine is cool before

unscrewing the coolant pressure relief cap.
The cooling system is under pressure. Steam
and hot liquid can come out forcefully when
you loosen the cap slightly.

Do not add coolant further than the
MAX mark.

When the engine is cold, check the
concentration and level of the coolant at the
intervals listed in the scheduled maintenance
information.  See Scheduled Maintenance
(page 483).

Note: Make sure that the coolant level is
between the MIN and MAX marks on the
coolant reservoir.

Note:  Coolant expands when it is hot.  The
level may extend beyond the MAX mark.

Maintain coolant concentration within 48%
to 50%, which equates to a freeze point
between -29°F (-34°C) and -35°F (-37°C).
Coolant concentration should be checked
using a refractometer. We do not recommend
the use of hydrometers or coolant test strips
for measuring coolant concentration.

Adding Coolant

WARNINGS

Do not add engine coolant when the
engine is hot. Failure to follow this

instruction could result in personal injury.

Do not remove the coolant reservoir
cap when the cooling system is hot.

Wait 10 minutes for the cooling system to
cool down. Cover the coolant reservoir cap
with a thick cloth to prevent the possibility
of scalding and slowly remove the cap.
Failure to follow this instruction could result
in personal injury.

MKT (TP4) , enUSA, Edition date: 201803, First-Printing

Maintenance

Note:  Automotive fluids are not
interchangeable.  Take care not to put
engine coolant in the windshield washer fluid
reservoir or windshield washer fluid in the
engine coolant reservoir.

Note:  Do not use stop leak pellets, cooling
system sealants, or non-specified additives
as they can cause damage to the engine
cooling or heating systems.  Resulting
component damage may not be covered by
the vehicle Warranty.

It is very important to use prediluted coolant
approved to the correct specification in order
to avoid plugging the small passageways in
the engine cooling system.  See Capacities
and Specifications (page 347).  Do not mix
different colors or types of coolant in your
vehicle. Mixing of engine coolants or using
an incorrect coolant may harm the engine or
cooling system components and may not be
covered by the vehicle Warranty.

Note: If prediluted coolant is not available,
use the approved concentrated coolant
diluting it to 50/50 with distilled water.  See
Capacities and Specifications (page 347).
Using water that has not been deionised
may contribute to deposit formation,
corrosion and plugging of the small cooling
system passageways.

Note:  Coolants marketed for all makes and
models may not be approved to our
specifications and may cause damage to
the cooling system.  Resulting component
damage may not be covered by the vehicle
Warranty.

If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.

To top up the coolant level do the following:

1. Unscrew the cap slowly. Any pressure

escapes as you unscrew the cap.

2. Add prediluted coolant approved to the

correct specification.  See Capacities and
Specifications (page 347).

3. Add enough prediluted coolant to reach

the correct level.

4. Replace the coolant reservoir cap, turn

it clockwise until you feel a strong
resistance.

5. Check the coolant level in the coolant

reservoir the next few times you drive
your vehicle. If necessary, add enough
prediluted engine coolant to bring the
coolant level to the correct level.

If you have to add more than 1.1 qt (1 L) of
engine coolant per month, have your vehicle
checked as soon as possible. Operating an
engine with a low level of coolant can result
in engine overheating and possible engine
damage.

Note: During normal vehicle operation, the
coolant may change color from orange to
pink or light red. As long as the coolant is
clear and uncontaminated, this color change
does not indicate the coolant has degraded
nor does it require the coolant to be drained,
the system to be flushed, or the coolant to
be replaced.

In case of emergency, you can add a large
amount of water without engine coolant in
order to reach a vehicle service location. In
this instance, qualified personnel:

293

MKT (TP4) , enUSA, Edition date: 201803, First-Printing

Maintenance

1. Must drain the cooling system.

2. Chemically clean the coolant system.
3. Refill with engine coolant as soon as

possible.

Water alone, without engine coolant, can
cause engine damage from corrosion,
overheating or freezing.

Do not use the following as a coolant
substitute:
•

Alcohol.

•

Methanol.

•

Brine.

•

Any coolant mixed with alcohol or
methanol antifreeze.

Alcohol and other liquids can cause engine
damage from overheating or freezing.

Do not add extra inhibitors or additives to
the coolant. These can be harmful and
compromise the corrosion protection of the
coolant.

Recycled Coolant

We do not recommend the use of recycled
coolant as an approved recycling process is
not yet available.

Dispose of used engine coolant in an
appropriate manner.  Follow your
community's regulations and standards for
recycling and disposing of automotive fluids.

Severe Climates

If you drive in extremely cold climates:
•

It may be necessary to increase the
coolant concentration above 50%.

•

A coolant concentration of 60% provides
improved freeze point protection. 
Coolant concentrations above 60%
decrease the overheat protection
characteristics of the coolant and may
cause engine damage.

If you drive in extremely hot climates:
•

You can decrease the coolant
concentration to 40%.

•

Coolant concentrations below 40%
decrease the freeze and corrosion
protection characteristics of the coolant
and may cause engine damage.

Vehicles driven year-round in non-extreme
climates should use prediluted coolant for
optimum cooling system and engine
protection.

Coolant Change

At specific mileage intervals, as listed in the
scheduled maintenance information, the
coolant should be changed. Add prediluted
coolant approved to the correct specification.
See Capacities and Specifications (page
347).

Fail-Safe Cooling

Fail-safe cooling allows you to temporarily
drive your vehicle before any incremental
component damage occurs. The fail-safe
distance depends on ambient temperature,
vehicle load and terrain.
