Maintenance

If you tow a trailer with your vehicle, the engine may temporarily reach a higher temperature during severe operating conditions, for example ascending a long or steep grade in high ambient temperatures. At this time, you may notice the coolant temperature gauge moves toward the red zone and a message may appear in the information display. You may notice a reduction in vehicle speed caused by reduced engine power in order to manage the engine coolant temperature. Your vehicle may enter this mode if certain high-temperature and high-load conditions take place. The amount of speed reduction depends on vehicle loading, grade and ambient temperature. If this occurs, there is no need to pull off the road. You can continue to drive your vehicle. The air conditioning may automatically turn on and off during severe operating conditions to protect the engine from overheating. When the coolant temperature decreases to the normal operating temperature, the air conditioning turns on.

If the coolant temperature gauge moves fully into the red zone, or if the coolant temperature warning or service engine soon messages appear in your information display, do the following: 1. Pull off the road as soon as safely possible and shift the transmission into park (P) . 2. Leave the engine running until the coolant temperature gauge needle returns to the normal position. If the temperature does not drop after several minutes, follow the remaining steps. 3. Switch the engine off and wait for it to cool. Check the coolant level. 4. If the coolant level is at or below the minimum mark, add prediluted coolant immediately. 5. If the coolant level is normal, restart the engine and continue.

AUTOMATIC TRANSMISSION FLUID CHECK 6F35/HF35 transmission (If Equipped) Note: Transmission fluid should be checked by an authorized dealer. If required, fluid should be added by an authorized dealer. The automatic transmission does not have a transmission fluid dipstick. Refer to your scheduled maintenance information for scheduled intervals for fluid checks and changes. Your transmission does not consume fluid. However, the fluid level should be checked if the transmission is not working properly, (For example: if the transmission slips or shifts slowly) or if you notice some sign of fluid leakage. See Scheduled Maintenance (page 509). Do not use supplemental transmission fluid additives, treatments or cleaning agents. The use of these materials may affect transmission operation and result in damage to internal transmission components.
