system. See Capacities and

Specifications (page 391). Do not mix

different colors or types of coolant in your

vehicle. Mixing of engine coolants or using

an incorrect coolant may harm the engine

or cooling system components and may

not be covered by the vehicle Warranty.

Note: If prediluted coolant is not available,

use the approved concentrated coolant

diluting it to 50/50 with distilled water. See

Capacities and Specifications (page 391).

Using water that has not been deionised

may contribute to deposit formation,

corrosion and plugging of the small cooling

system passageways.

Note: Coolants marketed for all makes and

models may not be approved to our

specifications and may cause damage to

the cooling system. Resulting component

damage may not be covered by the vehicle

Warranty.

In case of emergency, you can add a large

amount of water without engine coolant

in order to reach a vehicle service location.

In this instance, qualified personnel:

1. Must drain the cooling system.

2. Chemically clean the coolant system.

3. Refill with engine coolant as soon as

possible.

Water alone, without engine coolant, can

cause engine damage from corrosion,

overheating or freezing.

substances to come near the battery.

When working near the battery, always

shield your face and protect your eyes.

Always provide correct ventilation.

1. Park your vehicle on a level surface.

2. Look at the brake fluid reservoir to see

where the brake fluid level is relative

to the MIN and the MAX marks on the

reservoir.

Note: If the brake fluid level is between the

MIN and the MAX marks on the reservoir, it

is acceptable.

Note: If the brake fluid level is below the

MIN mark or above the MAX mark, have

your vehicle checked as soon as possible.

Note: To avoid fluid contamination, the

reservoir cap must remain in place and fully

tight, unless you are adding fluid.

WARNING: When lifting a

plastic-cased battery, excessive pressure

on the end walls could cause acid to flow

through the vent caps, resulting in

personal injury and damage to the

vehicle or battery. Lift the battery with a

battery carrier or with your hands on

opposite corners.

WARNING: Keep batteries out of

reach of children. Batteries contain

sulfuric acid. Avoid contact with skin,

eyes or clothing. Shield your eyes when

working near the battery to protect

against possible splashing of acid

solution. In case of acid contact with skin

or eyes, flush immediately with water for

a minimum of 15 minutes and get prompt

medical attention. If acid is swallowed,

call a physician immediately.

Only use fluid that meets our

specifications. See Capacities and

Specifications (page 385).

Brake Fluid Service Interval

Brake fluid absorbs water over time which

degrades the effectiveness of the brake

fluid. Change the brake fluid at the

specified intervals to prevent degraded

braking performance.

battery cables from only one battery

does not disconnect your vehicle

electrical system. Make sure you

disconnect the battery cables from all

batteries when disconnecting power.

Failure to do so may cause serious

personal injury or property damage.

Battery Management System ^(If

Equipped)

WARNING: For vehicles with

Auto-Start-Stop the battery requirement

is different. You must replace the battery

with one of exactly the same

specification.

The battery management system monitors

battery conditions and takes actions to

extend battery life. If excessive battery

drain is detected, the system temporarily

disables some electrical systems to

protect the battery.

The battery is in the engine compartment.

See Under Hood Overview (page 323).

Systems included are:

Your vehicle has a maintenance-free

battery. It does not require additional

water during service.

If the vehicle battery has a cover and vent

hose, make sure you correctly install it after

cleaning or replacing the battery.

For longer, trouble-free operation, keep the

top of the battery clean and dry and the

battery cables tightly fastened to the

battery terminals. If any corrosion is

present on the battery or terminals, remove

the cables from the terminals and clean

with a wire brush. You can neutralize the

acid with a solution of baking soda and

water.

make sure the ignition remains switched off.

Electrical Accessory Installation

Note: Make sure the battery cable terminals

are fully tightened.

To make sure the battery management

system works correctly, do not connect an

electrical device ground connection

directly to the battery negative post. This

can cause inaccurate measurements of

the battery condition and potential

incorrect system operation.

Note: If you add electrical accessories or

components to the vehicle, it may adversely

affect battery performance and durability.

This may also affect the performance of

other electrical systems in the vehicle.

If you disconnect or replace the vehicle

battery, you must reset the following

features:

•

Window bounce-back. See Power

Windows (page 96).

•

Clock Settings.
