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.
