Calm and smooth driving
Consistency is more important than speed. The more smoothly you drive, the less fuel the vehicle
consumes.
When driving on the highway or freeway, a constant, moderate speed is more efficient and economical
than constantly accelerating and braking. Usually you can reach your destination just as quickly by
driving at a moderate, but steady speed.
The cruise control system can assist in maintaining a uniform driving style.
Moderate use of extra electrical loads
Comfort inside the vehicle is nice and important, but it is important to use them in an environmentally
conscious manner.
Some devices can increase fuel consumption when activated (examples):
x Climate control system (air conditioner): If the air conditioner has to produce starkly contrasting
temperatures, it requires a large amount of energy, which is generated by the engine. The temperature
in the vehicle should therefore not be extremely different from that of the outside temperature. It may
be helpful to ventilate the vehicle before driving and then to drive a short distance with the windows
open. After that, switch on the air conditioner with the windows closed. Keep the windows closed when
driving at high speeds. Open windows increase fuel consumption.
x Switch off seat heating once it has served its purpose.
x Switch off the rear window defroster as soon as the windows are free of fog and ice.
Additional factors that increase fuel consumption (examples):
x Malfunctioning engine control.
x Driving in the mountains.
NOTICE
Never let the vehicle coast or roll down a hill in Neutral (N), especially when the engine is not
running. The transmission will not be lubricated and will be damaged.

Special considerations
When it is very hot and humid outside, water condensation can drip from the air conditioner
evaporator and form a puddle under the vehicle. This is normal and does not indicate a leak.
The climate control system adjusts the passenger compartment temperature as fast as possible
considering the outside temperature.
Due to residual moisture in the air conditioner, the windshield may fog up after the engine is
started. Switch on the windshield defroster to help evaporate the condensation as quickly as possible.
The air coming out of the vents flows through the passenger compartment and out through the
vents under the rear window. Do not cover these slots with clothing or other things.

Before removing the jumper cables
x Switch off the headlights (if they are on).
x In the vehicle with the dead battery, switch on the heater fan and the rear window defroster. This
helps to minimize voltage spikes when the cables are disconnected.
Removing jumper cables
With the engine running, remove the jumper cables in reverse order to the way they were connected.
1. Disconnect the black (-) cable from the vehicle with the dead battery.
2. Disconnect the black (-) cable from the other vehicle (vehicle with the good battery).
3. Disconnect the red (+) cable from the other vehicle (vehicle with the good battery).
4. Disconnect the red (+) cable from the vehicle with the dead battery.
5. Close the battery cover.
6. If necessary, unscrew the towing eye on the front of the vehicle..
WARNING
Improper use of jumper cables when jump-starting a vehicle with a dead battery can cause
the battery to explode, leading to serious personal injury. To help reduce the risk of battery
explosion:
x All work on the batteries or the electrical system in your vehicle can cause serious acid
burns, fires, or electrical shocks. Always read and heed the following WARNINGS and safety
precautions before working on the batteries or the electrical system., Vehicle battery.
x Always wear proper eye protection. Never lean over the vehicle battery.
x Attach the jumper cables in the correct order: first the positive cable, then the negative
cable.
x Never connect the negative cable from the vehicle providing starting assistance to parts
of the fuel system or to the brake hoses or brake lines.
x Never allow the non-insulated parts of the battery clamps to touch.
x Never allow the jumper cable attached to the positive battery terminal to contact metal
parts of the vehicle.
x Check the battery acid level indicator window on the vehicle battery. Use a flashlight,
never a match, cigarette lighter, or other open flame. If you cannot see the color of the
window clearly, or if it is light yellow or colorless, do not jump-start the vehicle. Get expert
assistance.
x Avoid electrostatic discharge in the vicinity of the vehicle battery. Sparks may cause the
hydrogen gas escaping from the vehicle battery to ignite.
x Never jump-start a vehicle with a battery that is damaged or frozen or that was frozen and
has thawed. The battery can explode. Replace the battery instead.
x Always follow the instructions of the jumper cable manufacturer.
x Always make sure that the battery providing starting assistance has the same voltage as
the dead battery (12 V) and about the same capacity (see battery label).
x Batteries give off explosive hydrogen gas. Always keep fire, sparks, open flame and
sm/+ing materials away from batteries.
x Never connect the negative cable from the other vehicle directly to the negative terminal
of the dead battery. The hydrogen gas from the battery is explosive.
x Never short out the battery terminals by connecting the positive (+) and negative (-)
terminals with each other.
