SERVICING AND MAINTENANCE
Correct servicing permits the performance of
the vehicle to be maintained over time, as well
as limited running costs and safeguarding the
efficiency of the safety systems.
SCHEDULED SERVICING
Correct servicing is crucial for guaranteeing a
long life for the vehicle under the best condi-
tions.
For this reason, Alfa Romeo has planned a
series of checks and services for your vehicle
at fixed intervals based on distance and time,
as described in the Scheduled Servicing Plan.
Before each service, it is always necessary to
carefully follow the instructions in the Sched -
uled Servicing Plan (e.g. periodically check
level of fluids, tire pressure, etc.).
Scheduled Servicing is offered by an autho -
rized dealer according to a set time schedule.
If, during each operation, in addition to the
ones scheduled, the need arises for further
replacements or repairs, these may be carried
out with the owner’s explicit consent only.

NOTE:

Scheduled Servicing intervals are required by
the manufacturer. Failure to have them
carried out may invalidate the New Vehicle
Limited Warranty.
You are advised to inform an authorized
dealer of any small operating irregularities
without waiting for the next service.
Periodic Checks
Every month or every 620 miles (1,000 km) or
before long trips check and, if necessary, top
off:
Engine coolant level.
Brake fluid level (if insufficient, see an
authorized dealer as soon as possible).
Windshield washer fluid level.
Tire inflation pressure and condition.
Operation of lighting system (headlights,
direction indicators, hazard warning lights,
etc.).
Operation of windshield washing/wiping
system and positioning/wear of wiper
blades.
Inspect the CV/Universal joints.
Oil consumption of the engine depends on
conditions and driving style. For this reason,
the engine oil level must be checked every
1,860 miles (3,000 km), and top off if neces -
sary; for further information
Ú
page 215.
Heavy Usage Of The Vehicle
If the vehicle is used under one of the following
conditions:
Dusty roads.
Short, repeated journeys less than 4 miles
(7 km) at sub-zero outside temperatures.
Engine often idling or driving long distances
at low speeds or long periods of inactivity.
In the event of a long period of inactivity.
The following checks must be carried out more
often than indicated in the Scheduled
Servicing Plan:
Check cleanliness of hood and liftgate
locks, cleanliness and lubrication of
linkage.
Visually inspect conditions of: engine, trans -
mission, pipes and hoses (exhaust/fuel
system/brakes) and rubber elements
(sleeves/bushes, etc.).
Check battery charge and battery fluid level
(electrolyte).
Visually inspect conditions of the accessory
drive belts.
Check and, if necessary, change engine oil
and replace oil filter.
Check and, if necessary, replace cabin air
filter.
Check and, if necessary, replace air cleaner.
Severe Duty All Models
Change engine oil at 4,000 miles (6,500 km)
if the vehicle is operated in a dusty and
off-road environment or is operated predomi -
nately at idle or only very low engine RPM. This
type of vehicle use is considered Severe Duty.

Both underinflation and overinflation affect
the stability of the vehicle and can produce a
feeling of sluggish response or over respon-
siveness in the steering.

NOTE:

Unequal tire pressures from side to side
may cause erratic and unpredictable
steering response.
Unequal tire pressure from side to side may
cause the vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling
resistance resulting in higher fuel consump -
tion.
Tread Wear
Improper cold tire inflation pressures can
cause abnormal wear patterns and reduced
tread life, resulting in the need for earlier tire
replacement. Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfort
-
able ride. Overinflation produces a jarring and
uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed
on the driver's side B-pillar or rear edge of the
driver's side door.
At least once a month:
Check and adjust tire pressure with a good
quality pocket-type pressure gauge. Do not
make a visual judgement when determining
proper inflation. Tires may look properly
inflated even when they are underinflated.
Inspect tires for signs of tire wear or visible
damage.
Inflation pressures specified on the placard
are always “cold tire inflation pressure”. Cold
tire inflation pressure is defined as the tire
pressure after the vehicle has not been driven
for at least three hours, or driven less than
1 mile (1.6 km) after sitting for a minimum of
three hours. The cold tire inflation pressure must not exceed the maximum inflation pres
-
sure molded into the tire sidewall.
Check tire pressures more often if subject to a
wide range of outdoor temperatures, as tire
pressures vary with temperature changes.
Tire pressures change by approximately 1 psi
(7 kPa) per 12°F (7°C) of air temperature
change. Keep this in mind when checking tire
pressure inside a garage, especially in the
Winter.
Example: If garage temperature = 68°F
(20°C) and the outside temperature = 32°F
(0°C) then the cold tire inflation pressure
should be increased by 3 psi (21 kPa), which
equals 1 psi (7 kPa) for every 12°F (7°C) for
this outside temperature condition.
Tire pressure may increase from 2 to 6 psi
(13 to 40 kPa) during operation. DO NOT
reduce this normal pressure build up or your
tire pressure will be too low.
Tire Pressures For High Speed Operation
The manufacturer advocates driving at safe
speeds and within posted speed limits. Where
speed limits or conditions are such that the
vehicle can be driven at high speeds, main -
taining correct tire inflation pressure is very
important. Increased tire pressure and
reduced vehicle loading may be required for
high-speed vehicle operation. Refer to an
authorized tire dealer or original equipment
vehicle dealer for recommended safe oper -
ating speeds, loading and cold tire inflation
pressures.
Unequal tire pressures from one side of
the vehicle to the other can cause the
vehicle to drift to the right or left.
Always drive with each tire inflated to the
recommended cold tire inflation pressure.
WARNING! (Continued)
CAUTION!
After inspecting or adjusting the tire
pressure, always reinstall the valve stem
cap. This will prevent moisture and dirt from
entering the valve stem, which could
damage the valve stem.

Recommended Cold Tire Inflation Pressures

For vehicle speeds below 100 mph (160 km/h),
recommended cold tire inflation pressures are
listed on the Tire And Loading Information
Placard located on driver’s side B-pillar or the
rear edge of the driver's side door.

When driving at speeds 100 mph (160 km/h)
and above, increased tire pressures and
reduced vehicle loading are required for
high-speed vehicle operation.For driving speeds above 100 mph (160 km/h)
recommended cold tire inflation pressures are
listed below under "High Speed Tire Inflation
Pressure". Vehicle loading condition must not
exceed 688 lbs. (312 kg) (driver + three
passengers + 88 lbs. (40kg) luggage).
2.0L Engine

NOTE:

Using tires of a different size, type, brand or design on the front and rear may adversely affect vehicle drive-ability. We recommend using only tires
approved by the manufacturer. The manufacturer cannot determine if unapproved tires are suitable for use and therefore cannot guarantee vehicle
safety in those conditions.
WARNING!
High speed driving with your vehicle under
maximum load is dangerous. The added
strain on your tires could cause them to fail.
You could have a serious collision. Do not
drive a vehicle loaded to the maximum
capacity at continuous speeds above
75 mph (120 km/h).

the wheel’s protective coating that helps keep
them from corroding and tarnishing.
When cleaning extremely dirty wheels
including excessive brake dust, care must be
taken in the selection of tire and wheel
cleaning chemicals and equipment to prevent
damage to the wheels. Select a non-abrasive,
non-acidic cleaner for aluminum or chrome
wheels.
NOTE:

If you intend parking or storing your vehicle for
an extended period after cleaning the wheels
with wheel cleaner, drive your vehicle and
apply the brakes to remove the water droplets
from the brake components. This activity will
remove the red rust on the brake rotors and
prevent vehicle vibration when braking.
Dark Or Low Gloss Wheels
Tire Types
All Season Tires — If Equipped
All Season tires provide traction for all seasons
(Spring, Summer, Autumn, and Winter). Trac
-
tion levels may vary between different all
season tires. All season tires can be identified
by the M+S, M&S, M/S or MS designation on
the tire sidewall. Use all season tires only in
sets of four; failure to do so may adversely
affect the safety and handling of your vehicle.
Summer Or Three Season Tires — If
Equipped
Summer tires provide traction in both wet and
dry conditions, and are not intended to be
driven in snow or on ice. If your vehicle is
equipped with Summer tires, be aware these
tires are not designed for Winter or cold driving
conditions. Install Winter tires on your vehicle
when ambient temperatures are less than
40°F (5°C) or if roads are covered with ice or
snow. For more information, contact an autho -
rized dealer.
Summer tires do not contain the all season
designation or mountain/snowflake symbol on
the tire sidewall. Use Summer tires only in sets
of four; failure to do so may adversely affect
the safety and handling of your vehicle.
Snow Tires
Some areas of the country require the use of
snow tires during the Winter. Snow tires can
be identified by a “mountain/snowflake”
symbol on the tire sidewall.
If you need snow tires, select tires
equivalent in size and type to the
original equipment tires. Use snow
CAUTION!
Avoid products or automatic car washes
that use acidic solutions or strong alkaline
additives or harsh brushes. Many
aftermarket wheel cleaners and automatic
car washes may damage the wheel's
protective finish. Such damage is not
covered by the New Vehicle Limited
Warranty. Only car wash soap is
recommended.
CAUTION!
Do not use scouring pads, steel wool, a
bristle brush, metal polishes or oven
cleaner. These products may damage the
wheel's protective finish. Such damage is
not covered by the New Vehicle Limited
Warranty. Only car wash soap is
recommended.
CAUTION!
If your vehicle is equipped with these
specialty wheels, DO NOT USE wheel
cleaners, abrasives, or polishing
compounds. They will permanently damage
this finish and such damage is not covered
by the New Vehicle Limited Warranty. HAND
WASH ONLY USING MILD SOAP AND WATER
WITH A SOFT CLOTH. Used on a regular
basis; this is all that is required to maintain
this finish.
WARNING!
Do not use Summer tires in snow/ice
conditions. You could lose vehicle control,
resulting in severe injury or death. Driving
too fast for conditions also creates the
possibility of loss of vehicle control.

tires only in sets of four; failure to do so may
adversely affect the safety and handling of
your vehicle.
Snow tires generally have lower speed ratings
than what was originally equipped with your
vehicle and should not be operated at
sustained speeds over 75 mph (120 km/h).
For speeds above 75 mph (120 km/h) refer to
original equipment or an authorized tire dealer
for recommended safe operating speeds,
loading and cold tire inflation pressures.
While studded tires improve performance on
ice, skid and traction capability on wet or dry
surfaces may be poorer than that of
non-studded tires. Some states prohibit
studded tires; therefore, local laws should be
checked before using these tire types.
Tire Chains and Traction Devices
It is possible to fit 13 mm chains on all the
tires except for R20.
Use of traction devices require sufficient
tire-to-body clearance. Follow these recom-
mendations to guard against damage.

NOTE:

Traction device must be of proper size for
the tire, as recommended by the traction
device manufacturer.
Use on rear tires only.
Check the tension of the snow chains after
the first few meters have been driven.
Using snow chains with tires with non-orig -
inal dimensions may damage the vehicle.
Using different tires sizes or types (M+S,
snow, etc.) between the front and rear axles
may adversely affect vehicle driveability,
with the risk of losing control of the vehicle
and resulting accidents.
Tire Rotation Recommendations
Tires on the front and rear axles of vehicles
operate at different loads and perform
different steering, driving, and braking func -
tions. For these reasons, they wear at unequal
rates. These effects can be reduced by timely
rotation of tires. Rotation will increase tread
life, maintain traction levels and contribute to
a smooth, quiet ride.
To resolve this problem, tires should be
rotated at each service interval (approximately
every 10,000 miles [16,000 km]). More
frequent rotation is permissible if desired. The
reasons for any rapid or unusual wear should
be corrected prior to rotation being performed.
Tire Rotations Not Recommended — If
Equipped
Due to different size tires and wheels on front
and rear axles tire rotation is not possible for:
2.0T GME Engine equipped with a different
front and rear tire size.
CAUTION!
To avoid damage to your vehicle or tires,
observe the following precautions:
Because of restricted traction device
clearance between tires and other
suspension components, it is important
that only traction devices in good condi -
tion are used. Broken devices can cause
serious damage. Stop the vehicle immedi -
ately if noise occurs that could indicate
device breakage. Remove the damaged
parts of the device before further use.
Install device as tightly as possible and
then retighten after driving about ½ mile
(0.8 km).
Do not exceed 30 mph (48 km/h).
Drive cautiously and avoid severe turns
and large bumps, especially with a loaded
vehicle.
Do not drive for a prolonged period on dry
pavement.
Observe the traction device manufac -
turer’s instructions on the method of
installation, operating speed, and condi -
tions for use. Always use the suggested
operating speed of the device manufac -
turer’s if it is less than 30 mph (48 km/h).
Do not use traction devices on a compact
spare tire.
CAUTION! (Continued)
