SAFETY AND ENVIRONMENT PROTECTION
Warning symbols in this guide
How can you reduce the risk of personal injury and prevent possible
damage to others, your vehicle and its equipment? In this guide, answers
to such questions are contained in comments highlighted by the warning
triangle symbol. These comments should be read and observed.
Warning symbols on your vehicle
When you see this symbol, it is
imperative that you consult the
relevant section of this guide before
touching or attempting adjustment
of any kind.
Protecting the environment
We must all play our part in
protecting the environment. Correct
vehicle usage and the authorized
disposal of waste cleaning and
lubrication materials are significant
steps towards this aim. Information in this respect is highlighted in this
guide with the tree symbol.
BREAKING-IN YOUR VEHICLE
Your vehicle does not need an extensive break-in. Try not to drive
continuously at the same speed for the first 1,600 km (1,000 miles) of
new vehicle operation. Vary your speed to allow parts to adjust
themselves to other parts.
Drive your new vehicle at least 800 km (500 miles) before towing a
trailer.
Do not add friction modifier compounds or special break-in oils during
the first few thousand kilometers (miles) of operation, since these
additives may prevent piston ring seating. SeeEngine oilin the
Maintenance and specificationschapter for more information on oil
usage.

WARNING LIGHTS AND CHIMES
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 toOn
board diagnostics (OBD-II)in theMaintenance and Specifications
chapter. 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 (if equipped):
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
Specificationschapter.

MULTI-FUNCTION LEVER
Windshield wiper:Rotate the end
of the control away from you to
increase the speed of the wipers;
rotate towards you to decrease the
speed of the wipers.
Windshield washer:Push the end
of the stalk:
•Quickly pressing the end of the
stalk switch causes a single wipe
without washer fluid.
•Push and hold the end of the
stalk to activate the washer. The
wash cycle will continue for up to
ten seconds or until released. After release, there will be three
clearing wipes.
Note:The windshield wiper will not automatically cycle if the washer
fluid is low, refer toWindshield washer fluidin theMaintenance and
Specificationschapter.
Moisture sensitive wipers (if equipped)
The moisture sensitive wipers will automatically activate when moisture
is present on the windshield and the multifunction switch is set to one of
five Auto sensitivity settings. The five Auto sensitivity settings determine
how often the wipers will wipe based upon the moisture on the
windshield. Rotating the knob from the Auto position towards the
windshield selects a higher sensitivity and more wipes will occur. For
fewer wipes, select a lower setting.
The wipers will continue to wipe as
long as the presence of moisture is
detected on the windshield. The
number of wipes that occur will vary
based on the amount of moisture
detected on the windshield and the
Auto setting. The sensitivity to
moisture is automatically increased
at night. When the ignition is turned ON, the wipers will perform one
wipe if one of the five Auto settings is selected.
