Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause expensive repairs. A warning light may
illuminate when a problem exists with one of your vehicle’s functions.
Many lights will illuminate when you start your vehicle to make sure the
bulb works. If any light remains on after starting the vehicle, have the
respective system inspected immediately.
Check engine:TheCheck Engine
indicator light illuminates when the
ignition is first turned to the ON
position to check the bulb. Solid
illumination after the engine is started indicates the On Board
Diagnostics System (OBD-II) has detected a malfunction. Refer to
OBD-IIin theMaintenance and Specificationschapter. If the light is
blinking, engine misfire is occurring which could damage your catalytic
converter. Drive in a moderate fashion (avoid heavy acceleration and
deceleration) and have your vehicle serviced immediately.
Under engine misfire conditions, excessive exhaust temperatures
could damage the catalytic converter, the fuel system, interior
floor coverings or other vehicle components, possibly causing a fire.
Check fuel cap:Illuminates when
the fuel cap may not be properly
installed. Continued driving with
this light on may cause the Check
engine warning light to come on,
refer toFuel filler capin theMaintenance and Specificationchapter.
Brake system warning light:To
confirm the brake system warning
light is functional, it will
momentarily illuminate when the
ignition is turned to the ON position when the engine is not running, or
in a position between ON and START, or by applying the parking brake
when the ignition is turned to the ON position. If the brake system
warning light does not illuminate at this time, seek service immediately
from your dealership. Illumination after releasing the parking brake
indicates low brake fluid level and the brake system should be inspected
immediately by your servicing dealership.

Driving a vehicle with the brake system warning light on is
dangerous. A significant decrease in braking performance may
occur. It will take you longer to stop the vehicle. Have the vehicle
checked by your dealer immediately.
Anti-lock brake system:If the
ABS light stays illuminated or
continues to flash, a malfunction has
been detected, have the system
serviced immediately. Normal
braking is still functional unless the brake warning light also is
illuminated.
Air bag readiness:If this light fails
to illuminate when ignition is turned
to ON, continues to flash or remains
on, have the system serviced
immediately. A chime will also sound when a malfunction in the
supplemental restraint system has been detected.
Safety belt:Reminds you to fasten
your safety belt. A chime will also
sound to remind you to fasten your
safety belt.
Charging system:Illuminates when
the battery is not charging properly.
Engine oil pressure:Illuminates
when the oil pressure falls below the
normal range, refer toEngine oilin
theMaintenance and
specificationschapter.
Multi-function: Automatic
transaxle/cooling system (On
SPI, Zetec E or automatic
transaxle vehicles only):
Momentarily illuminates when the
ignition is turned to the ON position and the engine is off. If the light
illuminates while driving, have your vehicle serviced.

If you smell exhaust fumes inside your vehicle, have your dealer
inspect your vehicle immediately. Do not drive if you smell
exhaust fumes.
Make sure the corresponding lights illuminate or illuminate briefly. If a
light fails to illuminate, have the vehicle serviced.
•If the driver’s safety belt is fastened, the
light may not illuminate.
Important safety precautions
When the engine starts, the idle RPM runs faster to warm the engine. If
the engine idle speed does not slow down automatically, have the vehicle
checked.
Before starting the vehicle:
1. Make sure all occupants buckle their safety belts. For more
information on safety belts and their proper usage, refer to theSeating
and safety restraintschapter.
2. Make sure the headlamps and electrical accessories are off.
If starting a vehicle with an automatic transaxle:
•Make sure the parking brake is
set.
•Make sure the gearshift is in P
(Park).
Driving

•Hitting a patch of ice
•Changing lanes on a snow-rutted road
•Entering a snow-free road from a snow-covered side street, or vice
versa
•Entering a paved road from a gravel road, or vice versa
•Hitting a curb while turning
•Cornering at excessive speeds while towing a heavily loaded trailer
(refer toTrailer Towingin this chapter)
The AdvanceTrac
system automatically turns on when the engine is
started. However, the system does not function when the vehicle is
traveling in R (Reverse).
The AdvanceTrac
button allows
the driver to control the availability
of the AdvanceTrac
system.
AdvanceTrac
system status is
indicated by a“sliding car”icon
indicator light in the instrument
cluster when the system is active.
If a failure is detected in the AdvanceTrac
system, the“sliding car”
icon indicator light in the instrument cluster will stay on.
If the vehicle is stuck in snow or mud or when driving in deep sand,
switching off the AdvanceTrac
system may be beneficial so the wheels
are allowed to spin. If your vehicle seems to lose engine power while
driving in deep sand or very deep snow, switching off the AdvanceTrac

stability enhancement feature will restore full engine power and will
enhance momentum through the obstacle.
Some drivers may notice a slight movement of the brake pedal when the
AdvanceTrac
performs a system self-check. During AdvanceTrac

operation you may experience the following:
•A rumble or grinding noise
•A slight deceleration of the vehicle
•The TRAC ACTIVE indicator light will illuminate
•If your foot is on the brake pedal, you will feel a vibration in the
pedal.
•If the driving condition is severe and your foot is not on the brake, the
brake pedal will move to apply higher brake forces. You may also hear
a whoosh of air from under the instrument panel during this severe
condition.
Driving
114

All these conditions are normal during AdvanceTrac
operation.
Do not alter or modify your vehicle’s suspension or steering; the
resulting changes to the vehicle’s handling can adversely affect
the AdvanceTrac
system. Also, do not install a stereo
loudspeaker near the front center console or under either front
seat. The speaker vibrations can adversely affect the
AdvanceTrac
sensors located in this area.
Aggressive driving in any road conditions can cause you to lose
control of your vehicle increasing the risk of severe personal
injury or property damage. The occurrence of an AdvanceTrac
event
is an indication that at least some of the tires have exceeded their
ability to grip the road; this may lead to an increased risk of loss of
vehicle control, vehicle rollover, personal injury and death. If you
experience a severe road event, SLOW DOWN.
STEERING
To prevent damage to the power steering system:
•Never hold the steering wheel at its furthest turning points (until it
stops) for more than a few seconds when the engine is running.
•Do not operate the vehicle with a low power steering pump fluid level
(below the MIN mark on the reservoir).
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
If the steering wanders or pulls, check for:
•an improperly inflated tire
•uneven tire wear
•loose or worn suspension components
•loose or worn steering components
•improper steering alignment
AUTOMATIC TRANSMISSION OPERATION (IF EQUIPPED)
Brake-shift interlock
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift lever from being moved from P (Park) when the ignition is
in the ON position unless the brake pedal is depressed.
Driving

•Allow more distance for stopping with a trailer attached.
•If you are driving down a long or steep hill, shift to a lower gear. Do
not apply the brakes continuously, as they may overheat and become
less effective.
•The trailer tongue weight should be 10–15% of the loaded trailer
weight.
•After you have traveled 80 km (50 miles), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
•To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park).
•Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer’s wheels.
RECREATIONAL TOWING
Follow these guidelines for your specific powertrain combination to tow
your vehicle with all four wheels on the ground (such as behind a
recreational vehicle).
These guidelines are designed to ensure that your transmission is not
damaged due to insufficient lubrication.
All Front Wheel Drive (FWD) vehicles:
If your vehicle is equipped with an automatic transaxle, you cannot tow
the vehicle with the front drive wheels on the ground. It is recommended
to tow your vehicle with the drive wheels on a dolly or two wheel car
hauling trailer.
In case of a roadside emergency with a disabled vehicle (without access
to wheel dollies, car hauling trailer or flatbed transport vehicle) your
vehicle can be flat towed (all wheels on the ground) under the following
conditions:
•Place the transmission in N (Neutral).
•Maximum speed is 56 km/h (35 mph).
•Maximum distance is 80 km (50 miles).
If your vehicle is equipped with a manual transaxle, and in the case of a
roadside emergency with a disabled vehicle (without access to wheel
dollies, car hauling trailer or flatbed transport vehicle) your vehicle can
be flat towed (all wheels on the ground) under the following conditions:
•Place the transmission in N (Neutral).
•Maximum distance is unlimited.

Do not attempt to push-start your vehicle. Automatic
transmissions do not have push-start capability; also, the
catalytic converter may become damaged.
Preparing your vehicle
When the battery is disconnected or a new battery is installed, the
transmission must relearn its shift strategy. As a result, the transmission
may have firm and/or soft shifts. This operation is considered normal and
will not affect function or durability of the transmission. Over time, the
adaptive learning process will fully update transmission operation.
1.Use only a 12–volt supply to start your vehicle.
2. Do not disconnect the battery of the disabled vehicle as this could
damage the vehicle’s electrical system.
3. Park the booster vehicle close to the hood of the disabled vehicle
making sure the two vehiclesdo nottouch. Set the parking brake on
both vehicles and stay clear of the engine cooling fan and other moving
parts.
4. Check all battery terminals and remove any excessive corrosion before
you attach the battery cables. Ensure that vent caps are tight and level.
5. Turn the heater fan on in both vehicles to protect any electrical
surges. Turn all other accessories off.
Connecting the jumper cables
1. Connect the positive (+) jumper cable to the positive (+) terminal of
the discharged battery.
Note:In the illustrations,lightning boltsare used to designate the
assisting (boosting) battery.
