Get Wheels and tires -> Winter operation Guide for Mercedes GLA SUV First Generation (2013-2019)

Treadwear indicators (TWI) are required by

law. Six indicators are positioned on the tire

tread. They are visible once the tread depth is

approximately á in (1.6 mm). If this is the

case, the tire is so worn that it must be

replaced.

Selecting, mounting and replacing

tires

Only mount tires and wheels of the same

type and make.

Exception: it is permissible to install a dif-

ferent type or make in the event of a flat

tire. Observe the "MOExtended tires (tires

with run-flat characteristics" section

(Y page 307).

Only mount tires of the correct size onto

the wheels.

After mounting new tires, break them in at

moderate speeds for the first 60 miles

(100 km), as they only reach their full per-

formance after this distance.

Do not drive with tires which have too little

tread depth, as this significantly reduces

the traction on wet roads (hydroplaning).

Replace the tires after six years at the lat-

est, regardless of wear.

MOExtended tires (tires with run-flat

properties)

With MOExtended tires (tires with run flat

characteristics), you can continue to drive

your vehicle even if there is a total loss of

pressure in one or more tires.

MOExtended tires may only be used in con-

junction with an active tire pressure loss

warning system or with an active tire pressure

monitor and on wheels specifically tested by

Mercedes-Benz.

Notes on driving with MOExtended tires with

a flat tire (Y page 307).

Vehicles equipped with MOExtended tires

are not equipped with a TIREFIT kit at the

factory. It is therefore recommended that

you additionally equip your vehicle with a

TIREFIT kit if you mount tires that do not

feature run-flat properties, e.g. winter tires.

A TIREFIT kit can be obtained from a quali-

fied specialist workshop.

Winter operation

General notes

Have your vehicle winterproofed at a qualified

specialist workshop at the onset of winter.

Observe the notes in the "Changing a wheel"

section (Y page 348).

Driving with summer tires

At temperatures below 45 ‡(+7 †), summer

tires lose elasticity and therefore traction and

braking power. Change the tires on your vehi-

cle to M+S tires. Using summer tires at very

cold temperatures could cause cracks to

form, thereby damaging the tires perma-

nently. Mercedes-Benz cannot accept

responsibility for this type of damage.

WARNING

Damaged tires can cause tire inflation pres-

sure loss. As a result, you could lose control of

your vehicle. There is a risk of accident.

Check the tires regularly for signs of damage

and replace any damaged tires immediately.

M+S tires

WARNING

M+S tires with a tire tread depth of less than

ã in (4 mm) are not suitable for use in winter

and do not provide sufficient traction. There is

a risk of an accident.

M+S tires with a tread depth of less than ã in

(4 mm) must be replaced immediately.

Winter operation

Wheels and tires

At temperatures below 45 ‡(+7 †), use win-

ter tires or all-season tires. Both types of tire

are identified by the M+S marking.

Only winter tires bearing the i snowflake

symbol in addition to the M+S marking pro-

vide the best possible grip in wintry road con-

ditions. Only these tires will allow driving

safety systems such as ABS and ESP

function optimally in winter. These tires have

been developed specifically for driving in

snow.

Use M+S tires of the same make and tread on

all wheels to maintain safe handling charac-

teristics.

Always observe the maximum permissible

speed specified for the M+S tires you have

mounted.

Once the winter tires are mounted:

Check the tire pressures (Y page 331).

Restart the tire pressure loss warning sys-

tem

(Y page 331) or restart the tire pres-

sure monitor

(Y page 334).

Snow chains

WARNING

If snow chains are mounted on the rear

wheels, the snow chains could cause abrasion

to the vehicle body or to chassis components.

This could cause damage to the vehicle or the

tires. There is a risk of an accident.

To avoid hazardous situations:

never mount snow chains on the rear

wheels

only mount snow chains in pairs on the

front wheels.

On some tire sizes there is not enough

space for snow chains. To avoid damage to

the vehicle or tires, observe the "Wheel and

tire combinations" section under "Tires and

wheels".

For safety reasons, Mercedes-Benz recom-

mends that you only use snow chains that

have been specially approved for your vehicle

by Mercedes-Benz, or are of a corresponding

standard of quality.

If you intend to mount snow chains, please

bear the following points in mind:

Snow chains may not be mounted on all

wheel/tire combinations. Permissible

wheel-tire combinations (Y page 352).

Only use snow chains when driving on

roads completely covered by snow.

Remove the snow chains as soon as possi-

ble when you come to a road that is not

snow-covered.

Local regulations may restrict the use of

snow chains. Observe the appropriate reg-

ulations if you wish to mount snow chains.

Do not exceed the maximum permissible

speed of 30 mph (50 km/h).

When snow chains are installed, never use

Active Parking Assist (Y page 189).

You may wish to deactivate ESP

(Y page 69) when pulling away with snow

chains installed. You can thereby allow the

wheels to spin in a controlled manner, ach-

ieving an increased driving force (cutting

action).

Tire pressure

Tire pressure specifications

WARNING

Underinflated or overinflated tires pose the

following risks:

the tires may burst, especially as the load

and vehicle speed increase.

the tires may wear excessively and/or

unevenly, which may greatly impair tire

traction.

the driving characteristics, as well as steer-

ing and braking, may be greatly impaired.

There is a risk of an accident.

Follow recommended tire inflation pressures

and check the pressure of all the tires includ-

ing the spare wheel:

monthly, at least

if the load changes

before beginning a long journey

under different operating conditions, e.g.

off-road driving

If necessary, correct the tire pressure.

Use a suitable pressure gauge to check the

tire pressure. The outer appearance of a tire

does not permit any reliable conclusion about

the tire pressure. On vehicles equipped with

the electronic tire pressure monitor, the tire

pressure can be checked in the on-board

computer.

The recommended tire pressures for the tires

mounted at the factory can be found on the

labels described here.

1.) Tire and Loading Information placard

on the B-pillar on the driver's side of the vehi-

cle (Y page 335).

The Tire and Loading Information placard con-

tains the recommended tire pressures for

cold tires. The recommended tire pressures

are valid for the maximum permissible load

and up to the maximum permissible vehicle

speed.

Recommended tire pressures

Option 2) Tire pressure table on the inside of

the fuel filler flap.

The tire pressure table contains the recom-

mended pressures for cold tires for various

operating conditions, i.e. differing load and

speed conditions.

Specifications shown in the examples of

tire pressure tables are for illustration pur-

poses only. Tire pressure specifications are

vehicle-specific and may deviate from the

data shown here. Tire pressure specifica-

tions applicable to your vehicle are located

in your vehicle's tire pressure table.

Example: tire pressure table for all tires permitted

for this vehicle by the factory

If a tire size precedes a tire pressure, the tire

pressure information following is only valid

for that tire size. The load conditions "partially

laden" and "fully laden" are defined in the

table for different numbers of occupants and

amounts of luggage. The actual number of

seats may differ.
