Checking Oil Level
To assure proper engine lubrication, 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.
There are three possible dipstick types,
Crosshatched zone.
Crosshatched zone marked SAFE.
Crosshatched zone marked with MIN at
the low end of the range and MAX at the
high end of the range.
Crosshatched zone marked with dimples
at the MIN and the MAX ends of the range.
NOTE:
Always maintain the oil level within the
crosshatch markings on the dipstick.
Adding 1 quart (1.0 liters) of oil when the
reading is at the low end of the dipstick
range will raise the oil level to the high end
of the range marking.
Adding Washer Fluid
The fluid reservoir is located in the front of
the engine compartment. Be sure to check
the fluid level in the reservoir at regular inter -
vals. Fill the reservoir with windshield washer
solvent (not radiator antifreeze) and operate
the system for a few seconds to flush out the
residual washer fluid.
When refilling the washer fluid reservoir,
take some washer fluid, apply it to a cloth or
towel, and wipe clean the wiper blades; this
will help blade performance.
WARNING!
Never smoke while working in the engine
compartment: gas and inflammable
vapors may be present, with the risk of
fire.
Be very careful when working in the
engine compartment when the engine is
hot: you may get burned. Do not get too
close to the radiator cooling fan: the
electric fan may start; danger of injury.
Scarves, ties and other loose clothing
might be pulled by moving parts.
CAUTION!
Be careful not to confuse the various
types of fluids while topping up: they are
not compatible with each other! Topping
up with an unsuitable fluid could
severely damage your car.
The oil level must never exceed the MAX
mark.
Always top up using engine oil of the
same specifications as that already in
the engine.
If the engine oil is being topped up, wait
for the engine to cool down before loos-
ening the filler cap, particularly for vehi -
cles with aluminium cap (if equipped).
WARNING: risk of burns!
Overfilling or underfilling the crankcase
will cause aeration or loss of oil pressure.
This could damage your engine.

Under normal operating conditions, the cata-
lytic converter will not require maintenance.
However, it is important to keep the engine
properly tuned to assure proper catalyst
operation and prevent possible catalyst
damage.
NOTE:
Intentional tampering with emissions control
systems can result in civil penalties being
assessed against you.
In unusual situations involving grossly
malfunctioning engine operation, a
scorching odor may suggest severe and
abnormal catalyst overheating. If this occurs,
stop the vehicle, turn off the engine and allow it to cool. Service, including a tune-up
to manufacturer's specifications, should be
obtained immediately.
To minimize the possibility of catalytic
converter damage:
Do not interrupt the ignition when the
transmission is in gear and the vehicle is
in motion.
Do not try to start the vehicle by pushing
or towing the vehicle.
Do not idle the engine with any ignition
components disconnected or removed,
such as when diagnostic testing, or for
prolonged periods during very rough idle or
malfunctioning operating conditions.
Cooling System
Coolant Checks
Check engine coolant (antifreeze) protec
-
tion every 12 months (before the onset of
freezing weather, where applicable). If the
engine coolant (antifreeze) is dirty or rusty
in appearance, the system should be
drained, flushed and refilled with fresh
engine coolant (antifreeze). Check the front
of the A/C condenser for any accumulation
of bugs, leaves, etc. If dirty, clean by gently
spraying water from a garden hose vertically
down the face of the condenser.
Damage to the catalytic converter can
result if your vehicle is not kept in proper
operating condition. In the event of
engine malfunction, particularly
involving engine misfire or other
apparent loss of performance, have your
vehicle serviced promptly. Continued
operation of your vehicle with a severe
malfunction could cause the converter to
overheat, resulting in possible damage to
the converter and vehicle.
CAUTION! (Continued)
WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam
from your radiator. If you see or hear
steam coming from under the hood, do
not open the hood until the radiator has
had time to cool. Never open a cooling
system pressure cap when the radiator or
coolant bottle is hot.
Keep hands, tools, clothing, and jewelry
away from the radiator cooling fan when
the hood is raised. The fan starts auto-
matically and may start at any time,
whether the engine is running or not.
When working near the radiator cooling
fan, turn the ignition to the OFF mode.
The fan is temperature controlled and
can start at any time the ignition is in the
ON mode.

Cooling System Pressure Cap
The cap must be fully tightened to prevent
loss of engine coolant (antifreeze), and to
ensure that engine coolant (antifreeze) will
return to the radiator from the coolant expan-
sion bottle/recovery tank if so equipped.
The cap should be inspected and cleaned if
there is any accumulation of foreign material
on the sealing surfaces.
Brake System
In order to assure brake system performance,
all brake system components should be
inspected periodically. Refer to the “Mainte -nance Plan” in this section for the proper
maintenance intervals.
Brake Master Cylinder
The fluid in the master cylinder should be
checked when performing under hood
services or immediately if the “Brake
Warning Light” is illuminated.
Be sure to clean the top of the master
cylinder area before removing the cap. If
necessary, add fluid to bring the fluid level
up to the requirements described on the
brake fluid reservoir. With disc brakes, fluid
level can be expected to fall as the brake
pads wear. Brake fluid level should be
checked when pads are replaced. However,
low fluid level may be caused by a leak and
a checkup may be needed.
Use only manufacturer's recommended
brake fluid. Refer to “Fluids And Lubricants”
in “Technical Specifications” for further
information.
WARNING!
Do not open hot engine cooling system.
Never add engine coolant (antifreeze)
when the engine is overheated. Do not
loosen or remove the cap to cool an over
-
heated engine. Heat causes pressure to
build up in the cooling system. To
prevent scalding or injury, do not remove
the pressure cap while the system is hot
or under pressure.
Do not use a pressure cap other than the
one specified for your vehicle. Personal
injury or engine damage may result.
WARNING!
Riding the brakes can lead to brake failure
and possibly a collision. Driving with your
foot resting or riding on the brake pedal
can result in abnormally high brake
temperatures, excessive lining wear, and
possible brake damage. You would not
have your full braking capacity in an
emergency. WARNING!
Use only manufacturer's recommended
brake fluid. Refer to “Fluids And Lubri -
cants” in “Technical Specifications” for
further information. Using the wrong
type of brake fluid can severely damage
your brake system and/or impair its
performance. The proper type of brake
fluid for your vehicle is also identified on
the original factory installed hydraulic
master cylinder reservoir.
To avoid contamination from foreign
matter or moisture, use only new brake
fluid or fluid that has been in a tightly
closed container. Keep the master
cylinder reservoir cap secured at all
times. Brake fluid in a open container
absorbs moisture from the air resulting
in a lower boiling point. This may cause
it to boil unexpectedly during hard or
prolonged braking, resulting in sudden
brake failure. This could result in a colli -
sion.

The suggested Front Wheel Drive (FWD) Tire
rotation method is the “forward cross” shown
in the following diagram. This rotation
pattern does not apply to some directional
tires that must not be reversed.Tire Rotation (Forward Cross)
The suggested Four Wheel Drive (4WD) Tire
rotation method is the “rearward cross”
shown in the following diagram.
Tire Rotation (Rearward Cross)
STORING THE VEHICLE
If the vehicle should remain stationary for
more than a month, observe the following
precautions:
Park your vehicle in a covered, dry and
possibly airy location the windows open
slightly.
Check that the Electric Park Brake is not
engaged.
Disconnect the negative (-) terminal from
the battery post and be sure that the
battery is fully charged. During storage
check battery charge quarterly.
If you do not disconnect the battery from
the electrical system, check the battery
charge every 30 days.
Clean and protect the painted parts by
applying protective waxes.
Clean and protect polished metal parts by
applying protective waxes.
Apply talcum powder to the front and rear
wiper blades and leave raised from the
glass.
Cover the vehicle with an appropriate
cover taking care not to damage the
painted surface by dragging across dirty
surfaces. Do not use plastic sheeting
which will not allow the evaporation of
moisture present on the surface of the
vehicle.
Inflate the tires at a pressure of +7.25 psi
(+0.5 bar) higher than recommended on
the tire placard and check it periodically.
Do not drain the engine cooling system.
Whenever you leave the vehicle stationary
for two weeks or more, idle the engine for
approximately five minutes, with the air
conditioning system on and high fan
speed. This will ensure proper lubrication
of the system, thus minimizing the possi -
bility of damage to the compressor when
the vehicle is put back into operation.
CAUTION!
Proper operation of four-wheel drive
vehicles depends on tires of equal size,
type and circumference on each wheel.
Any difference in tire size can cause
damage to the power transfer unit. Tire
rotation schedule should be followed to
balance tire wear.

CAUTION!
Mixing of engine coolant (antifreeze)
other than specified Organic Additive
Technology (OAT) engine coolant (anti -
freeze), may result in engine damage
and may decrease corrosion protection.
Organic Additive Technology (OAT)
engine coolant is different and should
not be mixed with Hybrid Organic Addi -
tive Technology (HOAT) engine coolant
(antifreeze) or any “globally compatible”
coolant (antifreeze). If a non-OAT engine
coolant (antifreeze) is introduced into
the cooling system in an emergency, the
cooling system will need to be drained,
flushed, and refilled with fresh OAT
coolant (conforming to MS.90032), by
an authorized dealer as soon as possible.Do not use water alone or alcohol-based
engine coolant (antifreeze) products. Do
not use additional rust inhibitors or anti -
rust products, as they may not be
compatible with the radiator engine
coolant and may plug the radiator.
This vehicle has not been designed for
use with propylene glycol-based engine
coolant (antifreeze). Use of propylene
glycol-based engine coolant (antifreeze)
is not recommended.
The use of products with different spec-
ifications than those indicated above
could cause damage to the engine that is
not covered by the warranty.
CAUTION! (Continued)
Use AdBlue® only according to DIN 70
070 and ISO 22241-1. Other fluids may
cause damage to the system: also
exhaust emissions would no longer
comply with the law.
The distribution companies are respon -
sible for the compliance of their product.
Observe the precautions of storage and
servicing, in order to preserve the initial
qualities. The manufacturer of the
vehicle does not recognize any guarantee
in case of malfunctions and damage
caused to the vehicle due to the use of
AdBlue® not in accordance with regula-
tions.
