PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE 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 immediately.
EXHAUST GAS
The best protection against carbon monoxide
entry into the vehicle body is a properly
maintained engine exhaust system.
Whenever a change is noticed in the sound of the
exhaust system, when exhaust fumes can be
detected inside the vehicle, or when the
underside or rear of the vehicle is damaged, have
a competent mechanic inspect the complete
exhaust system and adjacent body areas for
broken, damaged, deteriorated, or mispositioned parts. Open seams or loose connections could
permit exhaust fumes to seep into the passenger
compartment. In addition, inspect the exhaust
system each time the vehicle is raised for
lubrication or oil change. Replace as required.
CARBON MONOXIDE WARNINGS
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/
liftgate/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.
If it is necessary to sit in a parked vehicle with
the engine running, adjust your heating or
cooling controls to force outside air into the
vehicle. Set the blower at high speed.
WARNING!
Carbon monoxide (CO) in exhaust gases is
deadly. Follow the precautions below to
prevent carbon monoxide poisoning:
Do not inhale exhaust gases. They contain
carbon monoxide, a colorless and odorless
gas, which can kill. Never run the engine in a
closed area, such as a garage, and never sit
in a parked vehicle with the engine running
for an extended period. If the vehicle is
stopped in an open area with the engine
running for more than a short period, adjust
the ventilation system to force fresh, outside
air into the vehicle.
Guard against carbon monoxide with proper
maintenance. Have the exhaust system
inspected every time the vehicle is raised.
Have any abnormal conditions repaired
promptly. Until repaired, drive with all side
windows fully open.
When exiting the vehicle, always make sure
the ignition is in the off position, remove the
key fob from the vehicle, and lock your
vehicle.

Cable Disconnection
1. Disconnect the negative (-) end of the jumper
cable from the remote negative (-) post of the
vehicle with the discharged battery.
2. Disconnect the opposite end of the negative (-) jumper cable from the negative (-) post of
the booster battery.
3. Disconnect the positive (+) end of the jumper
cable from the positive (+) post of the booster
battery.

4. Disconnect the opposite end of the positive (+)
jumper cable from the remote positive (+) post
of the vehicle with the discharged battery, and
reinstall the protective cap.

If frequent jump starting is required to start your
vehicle, you should have the battery and charging
system inspected at an authorized dealer.
BUMP STARTING
Never jump start the engine by pushing, towing or
coasting downhill.

NOTE:
You cannot start a vehicle with an automatic
transmission by pushing it.
ENGINE OVERHEATING
If your vehicle is overheating, it will need to be
serviced at an authorized dealer.
Engine overheating may occur in situations such
as (but not limited to) extreme environmental
temperatures or frequent engine stops/starts.
If the engine becomes overheated, the Engine
Temperature Warning Light in the instrument
cluster will illuminate along with a dedicated
message

Ú
page 80.
In any of the following situations, you can reduce
the potential for overheating by taking the
appropriate action.
On the highways — slow down.
In city traffic — while stopped, place the
transmission in NEUTRAL, but do not increase
engine idle speed.

NOTE:
There are steps that you can take to slow down an
impending overheat condition:
If your Air Conditioner (A/C) is on, turn it off.
The A/C system adds heat to the engine
cooling system and turning the A/C off can
help remove this heat.
You can also turn the temperature control to
maximum heat, the mode control to floor and
the blower control to high. This allows the
heater core to act as a supplement to the
radiator and aids in removing heat from the
engine cooling system.

NOTE:

If the cooling fan does not operate while the
engine is running, the engine temperature will
increase. Stop the engine and contact an
authorized dealer.
If the engine continues to overheat or
frequently overheats, have the cooling system
inspected. The engine could be seriously
damaged unless repairs are made. Contact an
authorized dealer.
CAUTION!
Accessories plugged into the vehicle power
outlets draw power from the vehicle’s battery,
even when not in use (i.e., cellular phones,
etc.). Eventually, if plugged in long enough
without engine operation, the vehicle’s battery
will discharge sufficiently to degrade battery
life and/or prevent the engine from starting.
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 try to
open a cooling system pressure cap when the
radiator or coolant bottle is hot.
CAUTION!
Driving with a hot cooling system could
damage your vehicle. If temperature gauge
reads “H”, pull over and stop the vehicle. Idle
the vehicle with the air conditioner turned off
until the pointer drops back into the normal
range. If the pointer remains on the “H”, turn
the engine off immediately, and call for
service.

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 conditions.
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 Scheduled
Servicing Plan (e.g. periodically check level of
fluids, tire pressure, etc.).
Scheduled Servicing is offered by an authorized
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 necessary;
