We recommend the use of a wheel lift anddollies or flatbed equipment to tow yourvehicle. Vehicle damage could occur iftowed incorrectly, or by any other means.
Front-wheel and rear-wheel drive vehiclesmust have their designated drive wheelsoff the ground regardless of towingdirection. Use tow dollies to preventdamage to the transmission.
All-wheel or four-wheel drive vehiclesrequire that all wheels be off the groundusing a wheel lift and dollies or flatbedequipment. This prevents damage to thetransmission and drive system.
Note:You need to switch on the ignition tounlock the steering.
Note:Make sure you check the steeringcolumn before towing. It could lock if thebattery is dead.
FAIL-SAFE COOLING
WHAT IS FAIL-SAFE COOLING
Fail-safe cooling allows you to temporarilydrive your vehicle before any incrementalcomponent damage occurs due tooverheating.
The fail-safe distance depends on outsidetemperature, vehicle load and terrain.
HOW DOES FAIL-SAFE COOLINGWORK
If the engine reaches a presetover-temperature condition, the engineautomatically switches to alternatingcylinder operation. Each disabled cylinderacts as an air pump and cools the engine.
When this occurs, your vehicle stilloperates, however:
•Engine power is limited.
•The air conditioning system turns off.
Continued operation increases the enginetemperature, causing the engine tocompletely shut down. Your steering andbraking effort increases in this situation.
When the engine temperature cools, youcan re-start the engine.
Note:Have your vehicle checked as soonas possible to minimize engine damage.
DRIVING WHEN FAIL-SAFE MODEIS ACTIVATED
WARNING: Fail-safe mode is foruse during emergencies only. Operateyour vehicle in fail-safe mode only aslong as necessary to bring your vehicleto rest in a safe location and seekimmediate repairs. When in fail-safemode, your vehicle will have limitedpower, will not be able to maintainhigh-speed operation, and maycompletely shut down without warning,potentially losing engine power, powersteering assist, and power brake assist,which may increase the possibility of acrash resulting in serious injury.
WARNING: Do not remove thecoolant reservoir cap when the engine ison or the cooling system is hot. Wait 10minutes for the cooling system to cooldown. Cover the coolant reservoir capwith a thick cloth to prevent thepossibility of scalding and slowly removethe cap. Failure to follow this instructioncould result in personal injury.
Continued operation increases the enginetemperature, causing the engine tocompletely shut down. Your steering andbraking effort increases in this situation.
When the engine temperature cools, youcan re-start the engine. Have your vehiclechecked as soon as possible to minimizeengine damage.

Remember that the engine is capable ofautomatically shutting down to preventengine damage. In this situation:
1.Pull off the road as soon as safelypossible and switch the engine off.
2.If you are a member of a roadsideassistance program, we recommendthat you contact your roadsideassistance service provider.
3.If this is not possible, wait for a shortperiod of time for the engine to cool.
4.Check the coolant level. If the coolantlevel is at or below the minimum mark,add prediluted coolant immediately.
5.When the engine temperature cools,you can re-start the engine. Have yourvehicle checked as soon as possible tominimize engine damage.
Note:Driving your vehicle without repairincreases the chance of engine damage.

It is very important to use predilutedcoolant approved to the correctspecification in order to avoid plugging thesmall passageways in the engine coolingsystem. See Capacities andSpecifications (page 520). Do not mixdifferent colors or types of coolant in yourvehicle. Mixing of engine coolants or usingan incorrect coolant may harm the engineor cooling system components and maynot be covered by the vehicle Warranty.
Note:If prediluted coolant is not available,use the approved concentrated coolantdiluting it to 50/50 with deionised ordistilled water. See Capacities andSpecifications (page 520). Using water thathas not been deionised may contribute todeposit formation, corrosion and pluggingof the small cooling system passageways.
Note: Coolants marketed for all makes andmodels may not be approved to ourspecifications and may cause damage tothe cooling system. Resulting componentdamage may not be covered by the vehicleWarranty.
If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
To top up the coolant level do thefollowing:
1.Unscrew the cap slowly. Any pressureescapes as you unscrew the cap.
2.Add prediluted coolant approved tothe correct specification. SeeCapacities and Specifications (page520).
3.Add enough prediluted coolant toreach the correct level.
4.Replace the coolant reservoir cap. Turnthe cap clockwise until it contacts thehard stop.
5.Check the coolant level in the coolantreservoir the next few times you driveyour vehicle. If necessary, add enoughprediluted engine coolant to bring thecoolant level to the correct level.
If you have to add more than 1.1 qt (1 L) ofengine coolant per month, have yourvehicle checked as soon as possible.Operating an engine with a low level ofcoolant can result in engine overheatingand possible engine damage.
In case of emergency, you can add a largeamount of water without engine coolantin order to reach a vehicle service location.
Water alone, without engine coolant, cancause engine damage from corrosion,overheating or freezing.
Do not use the following as a coolantsubstitute:
•Alcohol.
•Methanol.
•Brine.
•Any coolant mixed with alcohol ormethanol antifreeze.
Alcohol and other liquids can cause enginedamage from overheating or freezing.
Do not add extra inhibitors or additives tothe coolant. These can be harmful andcompromise the corrosion protection ofthe coolant.
CHANGING THE COOLANT
For coolant change, see your authorizeddealer.
Changing the coolant is necessary atspecific mileage intervals listed in thescheduled maintenance information. SeeScheduled Maintenance (page 591).
