Periodic Safety Checks You Should Make
Outside The Vehicle
Tires
Examine tires for excessive tread wear and
uneven wear patterns. Check for stones, nails,
glass, or other objects lodged in the tread or
sidewall. Inspect the tread for cuts and cracks.
Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the
tires (including spare) for proper cold inflation
pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid
leaks. Also, if gasoline fumes are detected or if
fuel, or brake fluid leaks are suspected, the
cause should be located and corrected imme
-
diately.
Exhaust Gas
ONLY use the driver’s side floor mat on the
driver’s side floor area. To check for inter -
ference, with the vehicle properly parked
with the engine off, fully depress the
accelerator, the brake, and the clutch
pedal (if present) to check for interfer -
ence. If your floor mat interferes with the
operation of any pedal, or is not secure to
the floor, remove the floor mat from the
vehicle and place the floor mat in your
trunk.
ONLY use the passenger’s side floor mat
on the passenger’s side floor area.
ALWAYS make sure objects cannot fall or
slide into the driver’s side floor area when
the vehicle is moving. Objects can become
trapped under accelerator, brake, or
clutch pedals and could cause a loss of
vehicle control.
NEVER place any objects under the floor
mat (e.g., towels, keys, etc.). These
objects could change the position of the
floor mat and may cause interference with
the accelerator, brake, or clutch pedals.
WARNING! (Continued)
If the vehicle carpet has been removed
and re-installed, always properly attach
carpet to the floor and check the floor mat
fasteners are secure to the vehicle carpet.
Fully depress each pedal to check for
interference with the accelerator, brake,
or clutch pedals then re-install the floor
mats.
It is recommended to only use mild soap
and water to clean your floor mats. After
cleaning, always check your floor mat has
been properly installed and is secured to
your vehicle using the floor mat fasteners
by lightly pulling mat.
WARNING! (Continued)
WARNING!
Exhaust gases can injure or kill. They
contain carbon monoxide (CO), which is
colorless and odorless. Breathing it can
make you unconscious and can eventually
poison you. To avoid breathing (CO), follow
these safety tips:
Do not run the engine in a closed garage
or in confined areas any longer than
needed to move your vehicle in or out of
the area.

If you are required to drive with the trunk/lift -
gate/rear doors open, make sure that all
windows are closed and the climate control
BLOWER switch is set at high speed. DO NOT
use the recirculation mode.

11. Apply the adhesive label from the sealantbottle where it can be easily seen by the
driver as a reminder that the tire has been
treated with a Tire Service Kit, as well as
not to exceed the speed restriction for the
treated tire.
NOTE:

Only use original sealant cartridges, which can
be purchased at an authorized dealer.
Checking And Restoring Tire Pressure
The compressor can also be used to check
and, if necessary, restore the tire pressure.
Proceed as follows:
1. Make sure that the power switch is in the
O (off) position.
2. Connect the hose directly to the valve on the tire to be inflated.
3. Insert the plug into the socket in the passenger compartment or in the cargo
area and start the engine.
4. Start the compressor by putting the power switch to I (on). As soon as the correct
pressure is reached, put the power switch
to O (off). Air Compressor And Components
If the tire is overinflated, reduce the pressure
by pushing the PSI/BAR button and releasing
it when the correct pressure is reached.
JUMP STARTING
If your vehicle has a discharged battery, it can
be jump started using a set of jumper cables
and a battery in another vehicle, or by using a
portable battery booster pack. Jump starting
can be dangerous if done improperly, so
please follow the procedures in this section
carefully.

NOTE:

When using a portable battery booster pack,
follow the manufacturer's operating instruc -
tions and precautions.
WARNING!
Tire Service Kit is not a permanent flat tire
repair. Have the tire inspected and repaired
or replaced after using Tire Service Kit. Do
not exceed 50 mph (80 km/h) until the tire
is repaired or replaced. Failure to follow this
warning can result in injuries that are
serious or fatal to you, your passengers,
and others around you. Have the tire
checked as soon as possible at an
authorized dealer.
WARNING!
Do not adhere the speed restriction sticker
to the padded area on the steering wheel.
Adhering the speed restriction sticker to the
padded area on the steering wheel is
dangerous because the air bag may not
operate (deploy) normally resulting in
serious injury. In addition, do not adhere
the sticker to areas where warning lights or
the speedometer cannot be viewed.

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

Washer Fluid For Windshield/Headlights
The windshield and headlight (if equipped)
washer fluid reservoir is equipped with a tele-
scopic filler neck.
If the level is too low, remove reservoir cap and
lift the filler neck. Then, add the fluid
described
Ú
page 263. After filling the reser -
voir, lower the filler neck and install the reser -
voir cap until you hear it click.

NOTE:

The headlight washers are activated every 10
activations of the windshield washer.
note:
The headlight washing system will not work if
the liquid level is low (situation indicated by
the symbol on the instrument cluster display

Ú
page 69). The windshield washer will keep
working.
On vehicles equipped with headlight washers,
there is a reference notch on the dipstick:
ONLY the windshield/rear window washer
operates with the level below this reference.
Brake Fluid
Check that the fluid is at the maximum level. If
the fluid level in the tank is low, contact an
authorized dealer to have the system checked.
Automatic Transmission Activation System
Oil
The transmission control oil level should only
be checked at an authorized dealer.
Useful Advice For Extending The Life Of
Your Battery
To avoid draining your battery and make it last
longer, observe the following instructions:
When you park the vehicle, ensure that the
doors and liftgate are closed properly to
prevent any lights from remaining on inside
the passenger's compartment.
Do not keep accessories (e.g. radio, hazard
warning lights, etc.) switched on for a long
time when the engine is not running.
Before performing any operation on the
electrical system, disconnect the negative
battery cable.
If you wish to install electrical accessories
after purchasing the vehicle that require
permanent electrical supply (e.g. alarm, etc.),
or accessories which influence the electrical
supply requirements, contact an authorized
dealer, who’s qualified staff will evaluate the
overall electrical consumption.
NOTE:

After the battery is disconnected, the steering
must be initialized. The warning light on the
instrument cluster display switches on to indi
-
cate this. To carry out this procedure, simply
turn the steering wheel all the way from one
end to the other, and then turn it back to the
central position.Battery
The battery does not require the electrolyte to
be topped up with distilled water. A periodic
check carried out at an authorized dealer,
however, is necessary to check efficiency.
Follow the battery manufacturer's instructions
for maintenance.
CAUTION!
If the charge level remains under 50% for a
long time, the battery may be damaged by
sulfation, reducing its capacity and
efficiency during the vehicle start. The
battery is also more prone to the risk of
freezing (at temperatures as high as 14°F
(-10°C).
