CHANGING THE ENGINE AIR
FILTER
WARNING: To reduce the risk of
vehicle damage and personal burn injuries,
do not start your engine with the air
cleaner removed and do not remove it
while the engine is running.
When changing the air filter element, use
only the air filter element listed.
See
Capacities and Specifications (page 400).
For turbocharged equipped vehicles: When
servicing the air cleaner, it is important that
no foreign material enter the air induction
system. The engine and turbocharger are
susceptible to damage from even small
particles.
Change the air filter element at the proper
interval. See Scheduled Maintenance (page
459
). Note:
Failure to use the correct air filter
element may result in severe engine
damage. The customer warranty may be
void for any damage to the engine if the
correct air filter element is not used. 1. Release the clamps that secure the air
filter housing cover.
2. Carefully lift the air filter housing cover.
3. Remove the air filter element from the air
filter housing.
4. Wipe any dirt or debris from the air filter housing and cover to make sure no dirt
gets in the engine and to make sure you
have a good seal. 5.
Install a new air filter element. Be careful
not to crimp the filter element edges
between the air filter housing and cover.
This could cause filter damage and allow
unfiltered air to enter the engine if not
properly seated.
6. Install the air filter housing cover.
7. Engage the clamps to secure the air filter
housing cover to the air filter housing.
CHANGING THE FUEL FILTER
Your vehicle has a lifetime fuel filter that
integrates with the fuel tank. It does not need
regular maintenance or replacement.

Cleaning Wheels
Only use a recommended wheel and tire
cleaner to clean the wheels weekly. For
additional information and assistance, we
recommend that you contact an authorized
dealer.
1.
Use a sponge to remove heavy deposits
of dirt and brake dust.
2. Rinse well after cleaning.
Note: Do not apply a cleaning chemical to
warm or hot wheel rims and covers.
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 parking your vehicle.
This reduces the risk of corrosion of the
brake discs, brake pads and linings.
Do not clean the wheels when they are hot.
Note: Some car washes could damage
wheel rims and covers.
Note: Using non-recommended cleaners,
harsh cleaning products, chrome wheel
cleaners or abrasive materials could
damage wheel rims and covers. Cleaning the Engine Compartment
Use a vacuum cleaner to remove debris from
the screen area below windshield.
Note:
If you are not familiar with the parts
around the engine do not wash the engine
compartment. Avoid frequent engine
washes.
When washing the engine compartment:
• Never wash or rinse the engine while it
is hot or running.
• Never wash or rinse any ignition coil,
spark plug wire or spark plug well.
• Cover the battery, power distribution box,
and air filter assembly to prevent water
damage.
Note: If your vehicle has an engine cover
remove the cover before application of
shampoo and degreaser.
• Spray an approved engine shampoo and
degreaser on all parts that require
cleaning and rinse with water. Cleaning Stripes or Graphics
It is recommended to wash your vehicle by
hand however, pressure washing may be
used under the following conditions:
•
Use a spray with a 40° wide spray angle
pattern.
• Keep the nozzle at a 12 in (305 mm)
distance and 90° angle to your vehicle's
surface.
• Do not use water pressure higher than
2,000 psi (14,000 kPa)
.
• Do not use water hotter than 179°F (82°C).
Note: Holding the pressure washer nozzle
at an angle to the vehicle's surface may
damage graphics and cause the edges to
peel away from the vehicle's surface.
Cleaning Camera Lenses and Sensors
We recommend that you only use lukewarm
or cold water and a soft cloth to clean the
camera lens and sensors.
Note: Do not pressure wash camera lens
and sensors.

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
The air filter restriction gauge. 1
The engine oil level.
Function of all interior and the exterior lights.

Safety warning lamps, brake, ABS, airbag and seatbelt for operation.
The washer spray and wiper operation. Clean or replace blades as necessa\
ry.
Multi-Point Inspection
It is important to have the systems on your
vehicle regularly checked. This can help
identify potential issues and prevent major
problems. We recommend having the
following multi-point inspection performed
at every scheduled maintenance interval to
help make sure your vehicle keeps running
great. Multi-Point Inspection
