uuWhen Driving uTire Pressure Monitoring System (TPMS) - Required Federal Explanation
Driving
Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver ’s responsibility to maintain
correct tire pressure, even if un der-inflation has not reached the
level to trigger illumination of th e TPMS low tire pressure telltale.
Your vehicle has also been equi pped with a TPMS malfunction
indicator to indicate when the system is not operating properly.
The TPMS malfunction indicator is combined with the low tire
pressure telltale. When the syst em detects a malfunction, the
telltale will flash fo r approximately one minute and then remain
continuously illumina ted. This sequence will continue upon
subsequent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the system may
not be able to detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of reasons, including
the installation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow the TPMS to
continue to function properly.

Driving
Fuel Economy
Improving Fuel Economy
Achieving fuel economy is dependent on several factors, including driving
conditions, load weight, standby time, driving habits, and vehicle condition.
Depending on these and other factors, you may not achieve the rated fuel economy
of this vehicle.
You can optimize your fuel economy with proper maintenance of your vehicle.
Always maintain your vehicle in accordance with the messages displayed on the
driver information interface.
• Maintain the specified tire pressure.
• Do not load the vehicl e with excess cargo.
• Keep your vehicle clean. A buildup of snow or mud on your vehicle’s underside
adds weight and increases wind resistance.

Safety When Performing Maintenance
Some of the most important safe ty precautions are given here.
However, we cannot warn you of every conceivable hazard that can arise in
performing maintenance. Only you can decide whether you should perform a given
task.
• To reduce the possibility of fire or explos ion, keep cigarettes, sparks, and flames
away from the 12-volt battery, all High Volt age system, and all fuel related parts.
• Never leave rags, towels, or other flammable objects under the hood.
u Heat from the motor or the surrounding parts can ignite them, causing a fire.
• To clean parts, use a co mmercially available degreaser or parts cleaner, not
gasoline.
• Wear eye protection and pr otective clothing when working with the 12-volt
battery or compressed air.
• The vehicle must be in a stationary condition.
u Make sure your vehicle is parked on le vel ground, the parking brake is set, and
the power system is turned off.
• Be aware that hot parts can burn you.
u Make sure to let the power system cool thoroughly before touching vehicle
parts.
• Be aware that moving parts can injure you.
u Do not activate the power system unless instructed to do so.
Keep your hands and limbs away from moving parts.

from diesel-powered vehicles, replace the dust and pollen filter every 15,000 miles.
*2: Driving in mountainous areas at very low vehicle speeds results in higher transmission temperatures. This requires transmission fluid changes more frequently than recommended by the Maintenance
Minder. If you regularly drive your vehicle under these conditions, have the transmission fluid changed
every 31,250 miles.
