AUTO-START-STOP – FREQUENTLYASKED QUESTIONS
Why does the engine not always stopwhen I expect it to?
The system is designed to work in a way thatcomplements other vehicle systems, allowingthem to operate at optimum performance.
The system does not stop the engine if:
•The driver door is open.
•Your vehicle is at high altitude.
•The heated windshield is on.
•The engine is warming up.
•The outside temperature is too low ortoo high.
•The battery charge is low.
•The battery temperature is outside theoptimal operating range.
•The engine is required to run to maintaininterior climate and reduce fogging.
Why does the engine sometimesrestart when I do not expect it to?
The system is designed to work in a way thatcomplements other vehicle systems, allowingthem to operate at optimum performance.
The system restarts the engine if:
•You switch the heated windshield on.
•You switch maximum defrost on.
•Your vehicle starts to roll downhill inneutral.
•The engine is required to run to maintainadequate brake system assistance.
•The engine is required to run to maintaininterior climate and reduce fogging.
Can I permanently switch the systemoff?
No. The system plays an important role inreducing the fuel consumption and the CO2emissions.
Will the frequent engine starts causeparts to wear out?
Your vehicle has an enhanced battery andstarter motor that are designed for theincreased number of engine starts.

ROOF RACK
ROOF RACK PRECAUTIONS
WARNING: Read and follow themanufacturer's instructions when you arefitting a roof rack.
WARNING: When loading the roofracks, we recommend you evenly distributethe load, as well as maintain a low centerof gravity. Loaded vehicles, with highercenters of gravity, may handle differentlythan unloaded vehicles. Take extraprecautions, such as slower speeds andincreased stopping distance, when drivinga heavily loaded vehicle.
Note:If you use a roof rack, the fuelconsumption of your vehicle will be higherand you may experience different drivingcharacteristics.
You must place loads directly on thecrossbars fitted to the roof rack side rails.
Make sure that you securely fasten the load. Check the tightness of the load beforedriving and at each fuel stop.
ROOF RACK LOAD CAPACITIES
Maximum Recommended LoadDescription
100 lb (45 kg)Vehicles with a moonroof.
175 lb (79 kg)Vehicles without a moonroof.
Note:The maximum roof load is based onevenly distributing the load on the crossbars.
Note:When using a roof rack system, youmust subtract the weight of the roof racksystem from the maximum recommendedload to determine your actual maximumcargo load. See the roof rack systemmanufacturer for more information.

COLD WEATHER PRECAUTIONS
The functional operation of somecomponents and systems can be affected attemperatures below approximately -13°F(-25°C).
DRIVING ON SNOW AND ICE
WARNING: If you are driving inslippery conditions that require tire chainsor cables, then it is critical that you drivecautiously. Keep speeds down, allow forlonger stopping distances and avoidaggressive steering to reduce the chancesof a loss of vehicle control which can leadto serious injury or death. If the rear endof your vehicle slides while cornering, steerin the direction of the slide until you regaincontrol of your vehicle.
On ice and snow, you should drive moreslowly than usual. Your vehicle has a fourwheel anti-lock brake system, do not pumpthe brake pedal. See Anti-Lock BrakingSystem Limitations (page 232).
BREAKING-IN
Your vehicle requires a break-in period. Forthe first 1,000 mi (1,600 km), avoid driving athigh speeds, heavy braking, aggressiveshifting or using your vehicle to tow. Duringthis time, your vehicle may exhibit someunusual driving characteristics.
DRIVING ECONOMICALLY
The following helps to improve fuelconsumption:
•Drive smoothly, accelerate gently andanticipate the road ahead to avoid heavybraking.
•Regularly check your tire pressures andmake sure that they are inflated to thecorrect pressure.
•Follow the recommended maintenanceschedule and carry out therecommended checks.
•Plan your journey and check the trafficbefore you set off. It is more efficient tocombine errands into a single tripwhenever possible.
•Avoid idling the engine in cold weatheror for extended periods. Start the engineonly when you are ready to set off.
•Do not carry unnecessary weight in yourvehicle as extra weight wastes fuel.
•Do not add unnecessary accessories tothe exterior of your vehicle, for examplerunning boards. If you use a roof rack,remember to fold it down or remove itwhen not in use.
•Do not shift into neutral when you arebraking or when your vehicle is slowingdown.
•Shut all windows when driving at highspeeds.
•Switch off all electric systems when notin use, for example air conditioning. Makesure that you unplug any accessoriesfrom the auxiliary power points when notin use.

If your instrument cluster display resetsprematurely or becomes inoperative, youshould perform the oil change interval at sixmonths or 5,000 mi (8,000 km) from yourlast oil change. Never exceed one year or10,000 mi (16,000 km) between oil changeintervals.
You can drive your vehicle in such a way thatmay lead to higher oil consumption includingextended time at high engine speeds, highloads, engine braking, hard corneringmaneuvers, track and off-road usage. Underthese conditions, oil consumption ofapproximately 1 quart per 500 miles (1 literper 800 km) is possible. Check the engineoil level at every refueling and adjust tomaintain proper levels to avoid enginedamage.
You can also drive your vehicle in such a waythat dilutes and increases the level of oil byfrequent short trips that do not allow theengine to get to operating temperature,extended idling and low speed driving forlong periods of time.
It is important to rely upon your dealershipto properly diagnose and repair your vehicle.
We strongly recommend only using ourgenuine or our authorized re-manufacturedreplacement parts engineered for yourvehicle.
Additives and Chemicals
We do not recommend using chemicals oradditives not approved by us as part of yourvehicle’s normal maintenance. Please consultyour warranty information.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a normaloperating characteristic and, by itself, doesnot necessarily indicate a concern or that thefluid needs to be changed. Have discoloredfluids that also show signs of overheating orforeign material contamination checkedimmediately.
Make sure to change the vehicle’s oils andfluids at the specified intervals or inconjunction with a repair. Flushing is a viableway to change fluid for many vehiclesub-systems during scheduled maintenance.It is critical that systems are flushed only withnew fluid that is the same as that requiredto fill and operate the system or using ourapproved flushing chemical.

Tampering With a Noise ControlSystem
Federal laws prohibit the following acts:
•Removal or rendering inoperative by anyperson other than for purposes ofmaintenance.
•Repair or replacement of any device orelement of the design incorporated intoa new vehicle for the purpose of noisecontrol prior to its sale or delivery to theultimate purchaser or while it is in use.
•The use of the vehicle after any personremoves or renders inoperative anydevice or element of the design.
The U.S. Environmental Protection Agencymay presume to constitute tampering asfollows:
•Removal of hood blanket, fender apronabsorbers, fender apron barriers,underbody noise shields or acousticallyabsorptive material.
•Tampering or rendering inoperative theengine speed governor, to allow enginespeed to exceed manufacturerspecifications.
If the engine does not start, runs rough,experiences a decrease in engineperformance, experiences excess fuelconsumption or produces excessive exhaustsmoke, check for the following:
•A plugged or disconnected air inletsystem hose.
•A plugged engine air filter element.
•Water in the fuel filter and waterseparator.
•A clogged fuel filter.
•Contaminated fuel.
•Air in the fuel system, due to looseconnections.
•An open or pinched sensor hose.
•Incorrect engine oil level.
•Incorrect fuel for climatic conditions.
•Incorrect engine oil viscosity for climacticconditions.
Note:Some vehicles have a lifetime fuel filterthat is integrated with the fuel tank. Regularmaintenance or replacement is not needed.
Note:If these checks do not help you correctthe concern, have your vehicle checked assoon as possible.
